    专利说明:

    [0001] The invention belongs to the field of seats for transport vehicles. It relates more particularly to a seat for a cabin of a transport vehicle by land, sea or air. Such a seat is for example installed in a cabin of an aircraft.
    [0002] In general, the seats used in the transport vehicles are faced with congestion problems of the seat structure which must be compatible with the other structures of the vehicle, with space restrictions such as for example access to emergency exits, or the installation of equipment that can be temporarily mounted, while providing a desired level of comfort for the occupant of the seat. Often, the seat has adjustable elements accessible to the occupant of the seat that allow the latter to adapt the ergonomics of the seat to its anatomy or to specific conditions. Thus it is common for a seat to be adjustable, with a certain amplitude, in longitudinal position, seat height, inclination of the backrest ... For example the seat described in the patent application EP 2305561 comprises a rigid tub which the height is adjustable on legs of the leg that are tilted backwards. As a result of this arrangement, the rearmost part of the seat recoils when the bucket is raised and therefore risks interfering with a structure located behind the seat. In general, the mobile parts of the seat must avoid interference with other structures of the vehicle which leads to additional constraints that may limit the possibility of adjustment and may lead to the implementation of complex and cumbersome solutions that are all sources loss of reliability of the seat and increased manufacturing and maintenance costs. For these various reasons, a seat adapted to the environment of a location in a given vehicle is not necessarily adapted to the environment of another vehicle or other location in the same vehicle. In these situations, it is then necessary either to have a different seat to respond to particular situations, or to degrade the possibilities of adjusting the seat. For example, it is known in passenger transport aircraft that the possibility of tilting the back of a seat is suppressed or condemned when the seat is installed in the cabin with the back of the backrest very close to a partition. The present invention provides a seat whose structure is adapted to change the longitudinal position of a rearmost point of a seat without substantially affecting the seat adjustment possibilities. The invention relates to a vehicle seat comprising a tub, said tub having a seat and a backrest, integral with the seat or rigidly fixed to the seat, comprising a supporting structure on which is fixed the bucket and having fasteners for attaching the carrier structure to a vehicle structure, for example a vehicle floor or vehicle structure beams, a height of the bucket on the supporting structure being adjustable. In addition, the supporting structure: comprises a low subassembly forming a base of the seat and of which at least one tub support is mounted movable in height, in a substantially vertical direction determined by one or more fixed lower guide rails. in a benchmark seat, the lower structure; has a high subset assembled to the lower subset, mobile in rotation with respect to said low subset about a tilting axis, substantially perpendicular to an overall symmetry plane XZ of the seat, located on the low subset in an area near a lower end of the lower guide rail (s) and located on the top subset in an area near a lower end of the high subset; the upper subassembly comprises one or more substantially vertical upper guide rails situated above the lower guide rail or rails; and the tub is integral with the at least one tub support articulately at the seat around an axis perpendicular to the overall plane of symmetry of the seat and comprises guide elements, fixed to the backrest, sliding in the upper guide rails.
    [0003] The seat can be for example a seat for a passenger or a technical operator or for a driver or driver of the vehicle and the vehicle can be for example a rolling vehicle or a surface vessel or an aircraft. There is thus obtained a seat with a tub, whose seat and back are rigidly connected, the horizontal movement back and forth of an innermost point of the seat can be limited by a structure adjustment carrier, limiting the effects on the longitudinal inclination of the bucket height adjustments of the tub. To meet the needs of different inclinations for example due to a different environment of the seat, the high subset comprises at least two stable angular positions around the axis of tilting: a position inclined towards the rear and a rectified position. It is thus modified the space occupied by the seat in a rear part of the seat, especially when the tub is placed in a high position.
    [0004] In one embodiment, the bottom subassembly comprises at least two brackets, each bracket comprising a vertical leg, substantially vertical, comprising at least one lower guide rail extending over all or part of a length of the vertical branch. concerned. The vertical leg, and in particular a longitudinal axis of the at least one lower guide rail, is in practice an angle close to the vertical chosen to correspond to a desired forward or backward movement of the tub according to its height, for example an angle between 0 and 20 degrees. In one embodiment, the upper subassembly comprises at least two lateral uprights secured by at least one crossmember, each lateral upright comprising at least one upper guide rail. It is thus obtained a relatively light structure and rigid enough to take up the efforts transmitted by the back of the tub and which allows to change the inclination of the top subassembly. The locking means are for example arranged on the upper subassembly to immobilize in rotation about the tilting axis the high subassembly relative to the low subassembly and or are arranged on the low subassembly to immobilize. in rotation about the tilting axis the high subset with respect to said low subset. It is thus possible to release the rotation of the upper subassembly by an action on the locking means and to block this rotation to a desired angular position authorized by the locking means. In one embodiment, the tub support (s) each include at least one front arm facing the front of the seat and a front end of which is hinged under the seat. According to this arrangement, the efforts related to the weight of the tub and in particular to the weight of its occupant can be subjected to vertical accelerations are taken in an advanced longitudinal position under the seat to be transmitted to the base of the chair and allowing a tilting longitudinal of the package during changes in the angle of which is inclined the top subassembly or when moving up the bucket. In one embodiment, the front arm is without substantial permanent deformation when the seat is subjected to limit accelerations in use and deformable when the seat is subjected to accelerations of a crash case so as to absorb energy. Thus the arm undergoes, without any appreciable residual deformation, the acceleration that can be encountered under normal conditions of use, the deformations remaining in the elastic range of the front arm, and by irreversible deformations that absorb energy in the event of crash acceleration. limits the acceleration experienced by the occupant of the seat. In another embodiment, combinable with the preceding form, the front arm comprises dynamic energy absorption means in case of crash, for example rods absorbing energy by friction or by deformation. It is thus simplified the design of the arm, at least part of the energy related to accelerations in case of crash being absorbed the dynamic absorption means. According to one embodiment, the high subassembly comprises an angular position around the tilting axis, in which said high subassembly is lockable with respect to the low subassembly such that during vertical movements of the tub a part of the further back of the seat is, in the locked position of the upper subassembly, substantially fixed in a longitudinal direction of the seat, towards the front or rear of the seat, in a fixed seat reference relative to the lower subset. The seat thus has a stable position of the upper subassembly for which a rear limit of the seat is substantially fixed during changes in the height of the tub. Due to the slight tilting of the bucket to the rear during its descent in case of a crash, the passenger is also more inclined towards the rear which limits the risk of its sliding forward on the tub under the effect of acceleration due to the crash, a phenomenon known as submarining. The description and the drawings of a particular embodiment of the invention will make it possible to better understand the aims and advantages of the invention. It is clear that this description is given by way of example, and is not limiting in nature. In the drawings: FIG. 1 is a perspective view from the rear of an example of a seat according to the invention; FIG. 2 is a perspective view from the front of the carrying structure of the tub, without the tub, of the seat of FIG. 1; - Figure 3a shows a side view of the seat of Figure 1 in a low position and inclined rearward of the bucket; FIG. 3b illustrates in a side view the seat of FIG. 1 in the same lower position as in FIG. 3a with a slight inclination towards the rear of the tub and shows the difference in the position of the rear of the seat ; FIGS. 4a and 4b illustrate in profile view the seat of FIG. 1 in a position inclined towards the rear of the tub, as in FIG. 3a, in the low positions, FIG. 4a, and FIG. 4b, and shows the deviation on the position of the rear of the seat; FIGS. 5a and 5b illustrate, in profile view, the seat of FIG. 1 in a rectified position of the tub, as in FIG. 3b, in the low positions, FIG. 5a, and FIG. 5b, and shows the alignment of FIG. rear seat positions. Figure 1 shows, seen in perspective from the rear and against-10 dive, a seat 100 according to the invention. In the rest of the description will be used a seat mark X, Y, Z for the respectively longitudinal, transverse and vertical axes of the seat. Along the longitudinal axis X, terms such as "forward", "backward", "anterior", "posterior" ... will be used, and along the vertical axis Z, terms such as "high", "Down", "above", "below" ... referring to the common sense that would be given to them by an occupier of the seat. The seat has a vertical symmetry plane XZ. The seat 100 mainly comprises a bearing structure 10 holding a tub 20 for receiving an occupant in a seated position. The tub 20 comprises mainly a shell whose rigid structure forms a seat 21 and a backrest 22. This type of tub is known. It can be made for example of 25 composite materials which allows to obtain ergonomic shapes of the seat and back with a high rigidity and a relatively small mass. The rigid hull is also fixed various accessories, generally associated with seats such as aircraft seats, in particular cushions 30 of seat and backrest, armrests 23, a headrest 24, a safety harness 25, in the example shown with a retractor 26 of shoulder harness, means for locking / unlocking movement of the seat or bucket 20 relative to the supporting structure 10.
    [0005] The carrying structure 10 is shown in Figure 2 in perspective view without the tub and its accessory elements. The supporting structure 10 mainly comprises a low subset 5 11 and a high subset 12. The bottom subset 11 is a rigid structure with two side brackets 111, the two brackets being arranged substantially symmetrically with respect to a XZ vertical plane of symmetry of the seat near lateral edges of the seat. Each bracket 111 has a horizontal leg 114, substantially horizontal in the seat mark, and a vertical leg 112, substantially vertical or slightly inclined in the seat mark generally between 0 ° and 20 °. The two shafts 111 are fixed together by connecting bars 113 which are arranged to provide the lower subset 11 a rigidity adapted to the forces that may be experienced during the use of the seat. The lower subset 11 forms seat legs having fasteners 113 arranged on the horizontal branches 114 of the brackets 111 so as to fix the seat by said fasteners to a structure of the vehicle, in the illustrated example represented by rails of floor 90. Each vertical leg 112 has a lower guide rail 115 having a longitudinal axis oriented in a substantially vertical direction. A tub support 30 is movably arranged on the bracket 111 to which it is attached so as to be movable in height along the vertical leg 112 of the bracket considered. Each tub support 30 has an anterior arm 31 facing forward so as to extend under the seat 21 of the tub 20. Advantageously, the arm is designed not to undergo substantial permanent deformation under normal conditions. use of the seat, that is to say, in particular under the limiting conditions of accelerations undergone in use, and to absorb the energy by deforming in the case of acceleration of crash to limit the acceleration experienced by a occupying the seat. In one embodiment, not shown, the arm has sufficient rigidity not to be substantially deformed during accelerations related to a crash and to transmit forces to specific energy absorbers mounted on the seat or supporting the seat. In another embodiment, not illustrated, the arm incorporates dynamic energy absorption means in the event of a crash, for example rods absorbing energy by friction or by deformation.
    [0006] The bucket support 30 is movable in the direction determined by the lower guide rail 115 of the vertical leg 112 of the corresponding bracket 111, the displacement in the substantially vertical direction determined by the lower guide rail 115 being the only degree of movement of the bucket support in the seat mark.
    [0007] In the exemplary embodiment illustrated, each tub support 30 comprises two rollers or pads, not visible in FIG. 2, offset in the longitudinal direction of the lower guide rail 115 which fitly slide in a groove of said lower guide rail to allow said bucket support to be movable in a longitudinal direction of the lower, substantially vertical guide rail, by securing the bucket support in the other directions of movement and in rotation. Each front arm 31 is secured to the tub 20 by an articulated connection with the seat 21 about an axis 33 parallel to the transverse axis Y of the seat mark.
    [0008] The upper subassembly 12 comprises two lateral uprights 21 rigidly connected by at least one cross member 122 and arranged substantially vertically. The upper subassembly 12 is assembled to the lower subset 11 mobile in rotation about a tilting axis 32 oriented along the transverse Y axis of the seat mark.
    [0009] The tilting axis 32 is located on the bottom subassembly 11 in an area of each bracket 111 close to the connection between the horizontal branch 114 and the vertical branch 112 of the bracket considered, in practice in an area close to a lower end of the lower guide rails (115), and also close to the vehicle floor on which the seat is fixed, and adapted to take up the forces introduced into the seat at the tilt axis 32.; The tilting axis 32 is also located on the upper subassembly 12 in an area near a lower end 123 of each of the lateral uprights 21. It follows from this configuration of the low and high subsets that the subassembly 12 is articulated by a lower end of said subassembly high distance from the upper guide rails.
    [0010] A spacing between outer blanks of the lateral uprights 121 of the upper subset 12 corresponds to a functional clearance near and at least on a height common to the low and high subsets, to a spacing between inner blanks of the vertical branches 112 of the brackets 111 of the bottom subset.
    [0011] According to this arrangement, the lateral uprights 121 in a substantially vertical position are able to move in rotation about the tilt axis 32 between the brackets 111 and take positions, more or less inclined relative to the strict vertical determined by the orientation of the Y axis, substantially parallel to the vertical branches 112 of said brackets. A locking device 124 is arranged to release, in the unlocked position, and immobilize, in the locked position, in rotation about the tilting axis 32, the upper subassembly 12 with respect to the subassembly 20. locking 124 ensures immobilization of the upper subset 12 in at least two different angular positions around the tilting axis, the lateral uprights 121 of said high subset thus determining at least two inclinations of said high subset. Each lateral upright 121 further comprises in an upper portion of said upright at least one upper guide rail 125. As will be understood later, the lengths of the lower guide rails 115 and the upper guide rails 125 are such as carriages, rollers or sliding pads running in said lower and upper rails have substantially the same strokes. According to the arrangement just described of the structure 10 and its main components, the upper guide rails 125 can be inclined by a rotation about the tilting axis 32 with respect to the lower guide rails 115. which has the consequence, due to the position of said tilt axis, to move in the longitudinal direction X the upper guide rails 125, the lower guide rails 115 being stationary in the seat mark.
    [0012] A forward tilting of the upper subassembly 12 has the effect of moving the guide rails forward, an upper end 126 of each of the lateral uprights 121 advancing, as a first approximation, in the seat mark of hx sin ( alpha) if h is the distance from the upper end 126 to the tilt axis 32 and alpha is the value of the angle from which the high subset is tilted. It should be understood here that the angle alpha considered is small enough so that its cosine can be, in a first approximation, considered substantially equal to 1. Due to the position shifted downward relative to the upper guide rails 125 of the tilting axis 32, said upper guide rails 15 are moved generally in the longitudinal direction X by the rotation of the upper subassembly 12. Referring again to Figure 1, the tub 20 is integral with the structure 10 of firstly by the front arms 31 of the tub supports 30 and 20 on the other hand by guiding elements 28. Each front arm 31 holds the tub 20 to the lower subset 11 by an articulated connection with the seat 21 around it. an axis 33 parallel to the transverse axis Y of the seat mark. The guide members 28 are attached to the back 22 and include rollers or pads arranged to move in grooves of the upper guide rails 125. According to this arrangement when the tub 20 is moved up, the tub supports 30 follow. a fixed trajectory in the seat mark determined by the lower guide rails 115 and guide elements 28 follow a path determined by the upper guide rails 125 and thus dependent on the angle at which the top subassembly 12 is inclined relative to the low subassembly 11. Except in the particular case where the paths determined by the lower guide rails and the upper guide rails are parallel, the height displacement of the seat leads to an angular movement of the seat in a plane longitudinal, determined by the relative position of the lower guide rails 115 and upper guide rails 125, which is without constraint due to the articulated connection of the seat 21 on the front arms 31 and because of a connection of the guide elements 28 fixed to the backrest 22 allowing a rotation of the backrest relative to the top subassembly 12. By for example, the guide elements 28 are rollers whose axes are aligned and parallel to the transverse axis Y. For example, the guide elements 28 are skates mounted rotating on aligned axes parallel to the transverse axis Y. Thus when the upper guide rails 125 are more inclined towards the rear than the lower guide rails 115, the backrest moves back more, at the connection with the guide elements 28, than the seat at the connection. with the front arms 31, when the bucket is mounted, which has the effect of tilting the bucket fully back when climbing. The seat in the upper position is in this case more inclined to the rear in low position. Conversely, when the upper guide rails 125 are less inclined towards the rear than the lower guide rails 115, for example vertical, the backrest is less displaced, at the level of the connection with the guide elements 28, than the seat at the level of the connection with the front arms 31, when the bucket is mounted, which has the effect of tilting the bucket fully forward when climbing. The seat in the high position is in this case less inclined backwards than in the low position. The seat comprises locking means, not shown in the drawings, to allow vertical movements of the tub 20 and to immobilize the tub in desired positions in height. Such locking means are known in the field of seats and the weight of the seat and its occupant is, if necessary, compensated, at least partially, by spring elements such as force compensation connecting rods 34. locking 124 of the rotation of the upper subset 12 relative to the lower subset 11 consist for example of sliders 126 of the high subset that are engaged in bores, adjusted to avoid unwanted play, for example a bore 116a and a front bore 116b, of the lower subset to block the rotation about the tilt axis 32. In the configurations of the seat 100 illustrated in Figures 3a and 3b, a bearing surface of an occupant of the seat on the backrest 22 is slightly inclined backwards for ergonomic reasons.
    [0013] In Figure 3a the upper subassembly 12 is in a position tilted backwards relative to its position in Figure 3b, the bucket being adjusted to the same position in height, in the low position in this case. In the illustrated case, the tilting is at an angle of about two degrees only.
    [0014] A visible effect by comparing Figure 3a and Figure 3b is an advance in the seat mark by a distance dl of a rear limit of the seat. The displacement of the rearmost limit of the seat is indicated by a dashed line, depending on the angle at which the upper subassembly is immobilized, the seat on both FIGS. 3a and 3b being represented with the same position of the seats. X-axis fasteners. When the top subassembly 12 and its upper guide rails 125 are in a backward inclined position due to an inclination angle selected about the tilting axis, In the case of FIGS. 4a and 4b, the adjustment of the bucket 20 in a high position, FIG. 4b, with respect to a low position, FIG. 4a, has the consequence that the rear limit of the seat recedes, in the seat mark, a distance d2. This recoil occurs although the tub in the example shown rocking due to its change of position 30 in height of the order of two and a half degrees forward. When the upper subassembly 12 and its upper guide rails 125 are in an upright position due to a selected tilt angle, the case of FIGS. 5a and 5b, the rear limit of the seat when the tub 20 is in a high position, Figure 5b, relative to a low position, Figure 4a, will decline less than in the previous case, or even by a suitable choice of the angle of rotation, will not shrink significantly as in the example shown.
    [0015] It should be noted that, in the range of inclination angles considered for the upper subassembly 12 about the tilt axis 32, the desired displacement of the upper guide rails 125 is obtained with low angles of rotation, some degrees, generally less than ten degrees, which makes it possible to keep the lower and upper guide rails substantially parallel or with substantially the same relative angle and consequently the amplitude of the tilting of the tub when the tub is raised or lowered is that little affected. The seat which has just been described in detail is a non-limiting example of the invention. Those skilled in the art can make variants of the carrier structure in particular. Thus the exemplary embodiment of the carrier structure has a configuration where each of the up and down subsets have a symmetrical left / right structure of the working parts with two brackets, two uprights, two tub supports ... Although such a configuration has advantages in terms of symmetry for the transmission of efforts and in terms of safety in the event of failure of certain elements, the skilled person can take up the principles of the invention with unlined axial structures, by for example a seat with a base of the single-girder type, or conversely with subsets comprising more than two working elements, while the detailed description illustrates only two. The number and shape of the lower and upper guide rails 30 may also be different from those described or illustrated as long as the bucket support (s) and the backrest guide member (s) are each guided according to the desired trajectory during the movements. in height of the tub.
    [0016] There is thus obtained a seat 100, whose rigid tub 20 can be adjusted in height and adjusted in inclination towards the rear or towards the front, in which the main efforts of the tub are taken up at the level of the structure 10 on the under - Low set 11 which is rigid and directly attached to a vehicle structure. In addition, the positioning of the locking means 124 in an upper part of the lower subset 11 makes it possible not to introduce torsional forces at the level of the tilting axis 32 in the case of efforts towards or towards the rear.
    [0017] The seat 100 is therefore lighter and less expensive to produce and maintain and also has few moving parts. In particular the position in which the tub 20 is adjusted forward inclination allows to eliminate, or at least limit, the recoil of the rearmost part of the seat 100 when the seat is adjusted in height, without moving the bucket the seat which is maintained at the seat 21, and thus allows not to sacrifice the height adjustment, important to adapt the position of the seat according to the size of its occupant, when the rear limit of the seat should not back. This absence or limitation of the recoil is important when obstacles, for example a partition, are located behind the seat. It is thus possible to implement the same seat model 100 whether or not it is constrained by obstacles located behind the seat or that the seat model must be mounted on different vehicles is that the seat model must be mounted in different locations of the same vehicle. When a seat 100 is not constrained by a rear obstacle, the seat can be adjusted with an angle giving a tilt of the bucket to the rear. When a seat 100 is constrained by a rear obstacle, the seat is adjusted with an angle of the top subassembly 12 giving a reduced inclination 30 to the rear. Adjusting the angle of rotation forwards or backwards is achieved by unlocking the locking means 124 to release the rotation of the upper subset 12 relative to the lower subset 11 and to lock again. said locking means when the top subassembly has been brought to the desired position. Unlocking and locking locking means are for example implemented by operators in charge of the installation of seats or their maintenance. Unlocking and locking the locking means can also be implemented by the seat user, for example for technical reasons or personal choice if the seat does not risk mechanical interference with other elements of the vehicle. In a particular mode of implementation, the seat adjustment 100 is modified according to a variable environment of the vehicle in which the seat is installed. For example, the seat is installed close to a partition behind the seat with a separation distance which allows the seat to be used with a tilt of the subassembly top backwards in a first configuration of the partition, but which does not allow this inclination in a second configuration of the partition for example when the partition is thickened by a temporary shielding.
