The seat in which the back (12) may be tilted relative to the base (11) comprises a support (120) and a frame (20) with end plates (21, 22) between which is interposed a tilt-adjustment device (30) and a pivot mechanism (50) with a cheek (51) between support (120) and end plate (22), a lock (52) for holding back the back, a linkage piece (53) connecting this device (30) and this lock (52) and a safety device (54) preventing the back from folding down into a virtually horizontal shelf unless the back is placed in the upright position beforehand. Application to the seats of motor vehicles.

Seat with a tilting and folding back

A sitting-surface frame (10) and a backframe (1) are connected to one another, on each side of the seat, at two mutually spaced points, one comprising a tilting axle (34) and the other a folding-down axle (8). Each lateral branch (11) of the backframe has a serrated slot (4) engaged with a folding-down axle (8) fixed to the sitting surface and carries a tilting axle (34). The axle (34) is integral with a releasing lever (32) retained on the end of the sitting surface. The pivoting of the lever in one direction frees the tilting axle and allows the back to be folded down about the axle (8), while in the other direction it lifts the back, disengages the serrations (6) of the slot and makes it possible to change the inclination of the back.
