Abstract: A rear seat for a motor vehicle includes a seat part and a back rest pivo to the seat part. The seat is mounted so that it can be moved between an inoperative position, in which the seat part and back rest are folded together and positioned approximately parallel to the back rest of the vehicle's front seat, and several operative positions. The seat part is mounted to the floor of the vehicle by a first link. A second link is pivotally mounted at one end to the back rest and has a journal at the other end. A locking member is movable between a locking position in which it holds the journal pivotably to an adjacent part of the vehicle and an unlocked position in which the journal is released to allow the seat to be moved to its inoperative position.
