Description

The invention relates to a bench seat for a motor vehicle. A bench for a motor vehicle known to the applicant comprises a frame intended to be mounted on a floor of the vehicle, and a plurality of seats and backs mounted on said frame. The seats and backrests are movable between a position of use authorizing the occupancy of the seat by a passenger and a position of non-use prohibiting the occupancy of the seat by said passenger. The frame generally delimits under the seats a storage space for extending objects between the trunk of the vehicle and 10 space for the feet of passengers. In this context, if a passenger sits on the seat while objects extend between the boot and the space provided for his feet, said objects can strike the feet of the passenger during a braking of the vehicle, risking to hurt the passenger. The invention aims to mitigate this risk. The invention thus relates to a bench seat for a motor vehicle comprising: a support frame intended to be mounted on a floor of the vehicle; A first seat and a first backrest mounted on said frame, the first seat and / or the first backrest being movable between a use position and a non-use position; the frame defining a storage space under the first seat; 25 remarkable in that it comprises: - a movable door mounted on the frame between a closed position in which the storage volume is closed by said hatch, and an open position in which the storage volume is released by said trap; and a safety device designed to allow movement of the hatch from its closed position to its open position only when the first seat or backrest is positioned in the non-use position. The bench according to the invention has two configurations. In a first configuration, the first seat and the first seat are in the position of use, that is to say a position allowing the occupation of the seat by a passenger. Under these conditions, the safety device prohibits the movement of the hatch from its closed position to its open position. It is then impossible to extend an object between the trunk and the space provided for the feet of the passenger.

In a second configuration, the first file or the first seat is in the non-use position, that is to say a position no longer allowing the occupation of the seat by the passenger. Under these conditions, the safety device allows the movement of the hatch from its closed position to its open position. It is then possible to extend an object between the trunk and the space provided for the feet of the passenger. Thus, the seat according to the invention does not allow a passenger to sit on the seat while an object extends between the boot and space for the feet. The risk of injury mentioned above is therefore mitigated.

The bench seat may include one or more of the following features. It is envisaged that the bench comprises a second seat and a second backrest mounted on said frame, the second seat and / or the second backrest being movable between a position of use and a non-use position, and that the safety device is designed to allow the door to move from its closed position to its open position only when the second seat or backrest is positioned in the non-use position. In its preferred embodiment, the safety device is designed to allow movement of the hatch from its closed position to its open position only when the first file is positioned in the non-use position and when the second seat is positioned in position. non-use position. Preferably, the hatch is pivotally mounted on the frame.

It is envisaged that the second seat is pivotally mounted on the frame, and that the safety device comprises an abutment member mounted under the second seat and turned towards the hatch, this stop member being adapted so that: - when the second seat is in the use position, the abutment member bears against the hatch prohibiting its pivoting from its closed position to its open position; and when the second seat is in the non-use position, the stop member releases the hatch allowing its pivoting from its closed position to its open position. It is also envisaged that the safety device comprises: a connecting rod pivotally mounted on the armature between a first position and a second position; - A transmission rod pivotally mounted on the hatch on the one hand and on the connecting rod on the other hand; and in that the first backrest is pivotally mounted on the frame, and is shaped so that when the first backrest is positioned in the use position, the latter prohibits the pivoting of the connecting rod from its first position to its position. second position, and when the first folder is positioned in non-use position it allows the pivoting of the connecting rod from its first position to its second position.

With such an arrangement, when the backrest is in the position of use, it prohibits the pivoting of the connecting rod from its first position to its second position, and by the same prohibits the pivoting of the door from its closed position to its open position, through the transmission rod.

When the folder is in the non-use position, it allows the pivoting of the connecting rod from its first position to its second position, and by the same allows the pivoting of the hatch from its closed position to its open position, through the transmission rod.

Advantageously, the seat comprises a locking device of the hatch in the closed position and / or in the open position. Under these conditions, the locking device makes it possible to prevent the hatch from undesirably pivoting, for example during the running of the vehicle.

In one embodiment, the locking device is motorized. The locking device may be mechanically assisted by bistable springs. In its preferred embodiment, when the first and / or the second backrest is in the use position it extends substantially vertically, and when the first and / Or the second folder is in the non-use position it extends substantially horizontally. Finally, in its preferred embodiment, when the first and / or second seat is in the use position it extends substantially horizontally, and when the first and / or second seat is in the non-use position it extends substantially vertically. The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and with reference to the drawings, in which: FIG. 1 is a three-quarter front view of a bench seat according to the invention on which two seats and two folders are in use position; - Figure 2 is a three quarter front view of the bench of Figure 1 on which a folder is in the non-use position; - Figure 3 is a three quarter front view of the bench of Figure 1 on which a folder and a seat are in the non-use position; - Figure 4 is a low-angle view of the seat of Figure 1; - Figure 5 is a side view of the bench of Figure 1 on which a hatch is in the closed position; and - Figure 6 is a side view of the bench of Figure 1 on which the door is in the open position; Figure 7 is a partial view of three quarter front of the bench of Figure 1; - Figure 8 is an enlarged view of three quarter rear of a connecting rod of the seat of Figure 1; FIG. 9 is a three-quarter front view of an armature belonging to the bench of FIG. 1. FIGS. 1 to 9 are oriented in the same orthogonal reference frame connected to the armature and formed by x, y directions. and z. In the remainder of this description, the term "vertical" is used with reference to the direction z. The term "horizontal" is used with reference to the x and y directions.

The terms "front", "back", "on", and "under" are used with reference to a mounting position of the seat on a motor vehicle. Figure 1 illustrates a seat 1 according to the invention. The seat 5 1 comprises: - a frame 2 (hidden in FIG. 1) forming a support intended to be mounted on the floor of a motor vehicle; a plurality of lining elements 3 covering the armature 2; - seats 4 and 6; 10 - respective files 8 and 10; and - a hatch 12. The armature 2 (illustrated in FIG. 9) comprises a spar 14 extending parallel to the y direction. The spar 14 is mounted on rear legs 16a, 16b substantially vertical. At the ends of the spar 14 are attached two flanges 18a, 18b in the form of a stick extending in the plane xz. The armature 2 further comprises a bar 20. This bar 20 is bent so that it has portions 20a, 20b extending parallel to the direction x and a portion 20c extending parallel to the direction y connecting the portions 20a, 20b. The ends of the portions 20a, 20b are fixed, respectively, on the flanges 18a, 18b. The armature 2 further comprises a bar 22. This bar 22 is bent so that it has portions 22a, 22b extending parallel to the direction z forming front feet and a portion 22c 25 extending parallel to the direction y. The portion 22c is fixed along its length to the portion 20c. The spar 14, the bars 20, 22 and the rear legs 16a, 16b delimit a storage volume 23. The frame 2 further comprises: - crosspieces 24 connecting the portions 22a, 22b to the spar 14; - Hinge means 28 fixed on the portion 20c, adapted to allow pivoting of the seats 4, 6 on the frame 2 about a pivot axis parallel to the y direction; - Hinge means 30 fixed to the portion 22c adapted to allow pivoting of the hatch 12 on the armature 2 about a pivot axis parallel to the y direction; and a substantially vertical upright 32 fixed to the spar 14.

The hatch 12 is movable between a closed position (illustrated in Figures 1 to 5) in which the storage volume 23 is closed by the hatch 12, and an open position (illustrated in Figure 6) in which the storage volume 23 is not closed by the hatch 12. In the illustrated embodiment, when the hatch 12 is in the open position, it extends substantially horizontally inside the storage volume 23. When the hatch 12 is in the closed position, it extends substantially vertically. The bench 1 advantageously comprises a locking mechanism 40 of the hatch 12 in the closed position and in the open position.

The locking mechanism 40 (illustrated in Figures 4 and 7) comprises a roller 42 of oblong shape rotatably mounted on the hatch 12 about an axis of rotation parallel to the direction x. The roller 42 can be mounted on the face of the hatch 12 turned towards the inside of the storage volume 23. In this case, a handle for actuating the rotation of the roller 42 can be mounted on the face of the hatch 12 facing the 'outside. The locking mechanism 40 further comprises two rods 44 extending substantially parallel to the y direction. The rods 44 are pivotally mounted at two points of the roller 42 disposed on its largest diameter. The roller 42 and the rods 44 are designed so that a rotation of the roller 42 causes a translation of the rods 44 substantially parallel to the direction y. The locking mechanism 40 finally comprises indexing orifices (not shown) provided on the portions 20a, 20b, and 22a, 22b.

Under these conditions, when the roller 42 is oriented so that its largest diameter extends substantially parallel to the direction z, the rods 44 do not protrude from the edges of the hatch 12, and the latter can rotate freely between its closed position, and its open position. When the roller 42 is oriented so that its largest diameter extends substantially parallel to the y direction, the rods 44 project from the edges of the hatch 12 and are received: - inside the indexing holes arranged on the portions 20a, 20b to lock the hatch 12 in the open position; or - inside the indexing orifices formed on the portions 22a, 22b to lock the hatch 12 in the closed position.

The seats 4, 6 comprise a wire frame (visible in Figure 7), respectively, 50, 52 on which is fixed a lining. The seat 4 is pivotally mounted between a position of use in which it extends substantially horizontally (illustrated in Figures 1, 2, and 4), and a position of non-use (shown in Figures 3 , 5, and 6) in which it extends substantially vertically. Similarly, in the illustrated embodiment, the seat 6 is pivotally mounted between a use position and a non-use position. For this purpose, the frames 50, 52 are articulated on the hinge means 28 about a pivot axis extending parallel to the y direction.

The backs 8, 10 comprise a wire frame, respectively 58, 60 on which is fixed a lining. The backrest 10 is pivotally mounted between a position of use, in which the latter extends substantially vertically, and a non-use position in which it extends substantially horizontally. For this purpose, the frame 60 of the backrest 10 is articulated on the frame 2 about a pivot axis extending parallel to the direction y. The backrest 10 comprises a shell 59 on its rear face so that when the backrest 10 is in the non-use position, also called tablet position, the shell acts as a tablet.

The folder 8 is fixed. Also, the wired frame 58 is fixed without any degree of freedom on the frame 2. Here, the backrest 8 is shaped so that a removable headrest 66 can be secured, and alternately, disengaged therefrom. The seat 1 comprises a safety device 70 designed to allow the door 12 to move from its closed position to its open position only when the backrest 10 and the seat 4 are positioned in the non-use position, preventing any occupation of the seat. bench 1 by a passenger. The safety device 70 comprises an abutment member 72 mounted underneath the seat 4 and turned towards the hatch 12. In the embodiment illustrated, the abutment member 72 is an integral part of the frame 50 of the seat. sitting 4.

The stop member 72 is adapted so that: when the seat 4 is in the position of use, the stop member 72 bears against the hatch 12 preventing its pivoting from its closed position to its open position (such as illustrated in Figures 4 and 7); and when the seat 4 is in the non-use position, the stop member 72 does not bear against the hatch 12 allowing its pivoting from its closed position to its open position (as illustrated in FIGS. 6). Advantageously, the stop member 72 is pivotally mounted relative to the frame 50 about an axis extending parallel to the axis y so as to allow the disposition of luggage vertically in the storage volume 23. The device safety device 70 comprises a connecting rod 74 pivotally mounted on the upright 32 of the armature 2 between a first position (illustrated in FIGS. 5, 7 and 8) and a second position (illustrated in FIG. 6). The safety device 70 also comprises a transmission rod 76 pivotally mounted on the hatch 12 on the one hand and on the connecting rod 74 on the other hand. The hatch 12, the connecting rod 74, and the transmission rod 76 are arranged so that when the hatch 12 pivots from its closed position to its open position, the hatch 12 causes the pivoting of the connecting rod 74 of its first position to its second position, via the transmission rod 76. Conversely, when the hatch 12 pivots from its open position to its closed position, it causes the pivoting of the connecting rod 74 of its second position to its first position, through the transmission rod 76. The operation of the seat 1 will now be described. At first, the seats 4, 6 and the folders 8, 10 are in the position of use (as shown in Figure 1). Two passengers can then sit on the bench 1. Under these conditions, the frame 60 of the backrest 10 bears against the connecting rod 74 holding it in first position (as illustrated in FIGS. 7 and 8). Furthermore, the stop member 72 bears against the hatch 12 now the latter in the closed position. The pivoting of the hatch 12 from its closed position to its open position is thus prohibited. In a second step, one of the passengers rotates the backrest 10 in the tablet position (as illustrated in FIG. 2). A passenger can still sit on the seat 1. Under these conditions, the frame 60 of the backrest 10 no longer bears against the connecting rod 74, allowing the pivoting of this connecting rod 74 from its first position to its seat. second position. However, the seat 4 being in the position of use, the stop member 72 always bears against the hatch 12. Thus, the pivoting of the hatch 12 from its closed position to its open position remains prohibited. Third, one of the passengers rotates the seat 4 in the non-use position (as illustrated in Figures 3, 4 and 7). No more passengers can sit on the seat 1. In these conditions, the frame 60 of the backrest 10 does not bear against the connecting rod 74, allowing the pivoting of this connecting rod 74 from its first position to his second position. In addition, the stop member 72 no longer bears against the hatch 12. Also, the pivoting of the hatch 12 from its closed position to its open position is authorized. For example, the passenger manually rotates the hatch 12 in the open position. The pivoting of the hatch in the open position causes the retraction of the transmission rod 76 and consequently the pivoting of the connecting rod 74 until the latter bears against the frame 60 of the backrest 10 in the tablet position. Thus, the connecting rod 74 pivots from its first position to its second position. Then, the passenger locks the hatch 12 in its open position by means of the locking mechanism 40. In a fifth time, a passenger wishes to sit on the seat 1 while the hatch 12 is open. For this purpose, according to a first alternative the passenger tries to rotate the seat 4 from its non-use position to its position of use. Under these conditions, the abutment member 72 comes to bear against the hatch 12. The latter being locked in the open position, it prohibits the positioning of the seat 4 in the position of use, and the passenger can not s' 1. In a second alternative, the passenger tries to rotate the backrest 10 from its tablet position to its position of use. The backrest 10 then bears on the connecting rod 74 to rotate it from its second position to its first position. The hatch 12 is locked in the open position, it prohibits the pivoting of the connecting rod 74. Thus, the seat 1 according to the invention is advantageous in that it does not allow any passenger to sit if the hatch 12 is in the open position.

The invention is not limited to the sole embodiment of the bench described above by way of example, it encompasses all the variants. For example, it is envisaged that the bench includes a seat and a back for a single passenger.
