- the backrest and the seat each comprise a reception face adapted to receive a seat occupant in the nominal position, and said reception faces face each other in the folded position;
- the vehicle seat further comprises an anchoring mechanism adapted to take alternately an active state in which it secures the folder to the foot in the folded position, and an inactive state in which it releases it; and
- FIG. 1 is a schematic side view of a seat in nominal position
- FIG. 2 is a sectional view of an example of a fixing mechanism
- FIGS. 3a and 3b are views corresponding to FIG. 1 of the seat of Figure 1 in positions respectively inclined and folded seat.
- Figure 1 shows a vehicle seat 1 automobile adapted to receive one or more occupants, and mounted on a chassis 2 of a motor vehicle.
- a seat can be mounted in various orientations in the vehicle, the terms “front”, “rear”, “left”, “right” and other orientation terms relating to the seat in the description referring only to the orientation of the seat. seat itself, irrespective of the orientation of the seat in the vehicle, unless explicitly stated otherwise.
- such a seat may be a so-called "last row” seat, that is to say the row located farthest from the driver's seat, for example a third-row seat.
- the seat 1 in its nominal position in which an occupant classically occupies the seat, the seat 1 comprises a backrest 6, presenting a front face 6a intended to receive the back of the occupant and an opposite rear face 6b.
- the backrest is mounted on a foot 7 secured to the frame 2 by means of a folder linkage.
- the seat is shown attached to the chassis of a vehicle having a loading line 12.
- This linkage backrest comprises a pair of rods before 8 parallel (a single front link 8 visible in Figure 1) extending between a first end 8a pivotally mounted on the foot 7 and a second end 8b pivotally mounted on the backrest 6.
- This back linkage also comprises a pair of parallel rear connecting rods 9 (only one rear connecting rod 9 visible in FIG. 1) extending between a first end 9a pivotally mounted on the foot 7 and a second end 9b pivotally mounted on the backrest 6. .
- a deformable quadrilateral is thus produced by the connecting points between the elements 8a, 8b, 9b, 9a. In the nominal position shown, it will be noted that this quadrilateral is crossed, that is to say that its sides made by the connecting rods before 8 and rear 9 intersect.
- the seat also comprises a seat 10 adapted to receive the pelvis and legs of the occupant.
- the seat 10 extends from a rear end to a front end and has an upper face 10a for receiving the pelvis and legs of the occupant and an opposite lower face 10b.
- the seat is mounted on the foot 7 by means of a seat crank.
- This seat linkage comprises a pair of front rods 11 parallel (a single front link 11 visible in Figure 1) extending between a first end 11 pivotally mounted on the foot 7 and a second end 11b pivotally mounted on the seat 10.
- the forward connecting rods 11 extend for example upwards and backwards, in the axis of the backrest, in the nominal position of the seat.
- the selected orientation of the rods 11 and 9 allows better retention of the occupant in the seat in the event of a vehicle shock in the seat axis.
- This seat linkage also includes a pair of rear connecting rods which, in the example shown, are common with the back 9 rear connecting rods presented above.
- the rear seat rod 9 is considered to extend between a foot connection end 7 which, in the example presented, is common with the connecting end 9a presented. above, and a connecting point 9c pivotally mounted on the seat 10.
- connection point 9c extends substantially between the first 9a and second 9b ends of the rear connecting rod 9 back, and the rear of an imaginary line joining these two ends 9a, 9b.
- a deformable quadrilateral is thus produced by the connection points between the elements 11a, 11b, 9c, 9a.
- this quadrilateral is substantially a trapezium.
- the length of the front link 11 between its two ends 11a and 11b is substantially equal (within 15%) to the length of the rear link 9 between its first end 9a and its connection point 9c.
- the rear connecting rods 9 extend for example upwards and forwards in the nominal position of the seat.
- the seat 1 of this example has a folding control member 14 such as, for example, a handle located on the rear face of the backrest, and adapted so that the user can, by actuating it, bring the seat into a position folded in which the folder extends substantially parallel to the seat, for example under the loading line.
- This tilt control member 14 is part of a tilt control system, for example a cable system, for transmitting the tilt control of the occupant to a locking mechanism of the seat.
- locking mechanism 21 is described below in connection with Figure 2.
- a pin 15 extending from the front rod 8 along an axis perpendicular to the plane of the drawing.
- a hook 16 comprises a connecting portion 17 at which it is mounted so that pivoting on a frame of the backrest 6, and a locking portion 18 having a shape complementary to the pin 15.
- the hook 16 is connected to the folding control 14 by means of a cable 19 and can thus be moved, by rotation around the pivot axis 17, by one actuation of the folding control member 14 by a user, between: an active position, shown in Figure 2, in which its locking portion 18 cooperates with the pin 15 to prohibit relative movement of the backrest 6 and the front rod 8, and an inactive position in which its locking portion 18 is released from the pin 15, which allows a relative movement of the backrest 6 and the front rod 8.
- the folding is assisted by a spring, not shown, for example a spiral spring at one of the pivots such as the pivot 11a.
- a spring not shown, for example a spiral spring at one of the pivots such as the pivot 11a.
- the front face 6a of the backrest 6 extends substantially horizontally and / or parallel to the seat 10 facing the upper face 10a thereof.
- the seat thus holds in a reduced height in this position, in which it can be retracted under the floor line 12.
- the rear face 6b of the backrest then realizes a flat loading floor.
- the seat can be fixed to the foot 7 by any suitable mechanism.
- a belt 22 extending, normally on the rear face 6b of the backrest and having a first end 22a fixed, for example sewn, to the backrest, and a second end 22b integral with the chassis of the vehicle, for example at the level of the loading line 12, or for example to a seat located in front of the seat considered and also retracted into the floor, or other.
- the end 22b of the belt 22 is provided with a self-gripping strip cooperating with a self-gripping strip complementary to the frame / other seat.
