Vehicle seat
First Claim
1. A vehicle seat comprising a seat back and a seat proper, the seat back having opposite first and second sides, and comprising, at least:
- a bottom portion mounted to pivot on a support framework about a first transverse horizontal pivot axis;
a top portion mounted to pivot on the bottom portion about a second transverse horizontal pivot axis, parallel to the first axis;
at least one first hinge mechanism adapted to make it possible to adjust the angular position of the seat back relative to the support framework, said hinge mechanism having a first cheek plate fastened to the support framework and a second cheek plate connected to the bottom portion of the seat back by a locking member that is movable between firstly a locking position in which said locking member secures the second cheek plate to the bottom portion of the seat back at least in a normal in-use angular position, and secondly an unlocking position in which said locking member makes it possible for the bottom portion of the seat back to pivot freely relative to the support framework, at least for the purpose of folding down said bottom portion from its normal in-use position to a tilted-forwards position;
a second hinge mechanism connecting the top portion of the seat back to the bottom portion and actuatable so as selectively either to secure the top portion of the seat back to the bottom portion, or to allow the top portion of the seat back to pivot relative to the bottom portion about the second axis, at least for the purpose of folding down said top portion from the normal in-use position to a folded-down forwards position;
wherein the first and second hinge mechanisms are disposed on respective ones of the first and the second sides of the seat back, the top portion of the seat back being connected to the bottom portion of said seat back via a freely pivoting mount on the first side of the seat back.

Abstract
A vehicle seat comprising a seat proper and a seat back comprising a bottom portion pivotally mounted on the seat proper via a first hinge mechanism situated on a first side of the seat back, and a top portion pivotally mounted on the bottom portion via a second hinge mechanism situated on the second side of the seat back, the top portion being mounted to pivot freely on the bottom portion on the first side of the seat back. On said second side, one of the cheek plates of the first hinge mechanism is connected to the bottom portion of the seat back by a locking member making it possible either to secure said cheek plate to the bottom portion of the seat back, or to allow said bottom portion of the seat back to pivot freely.
