Abstract

A catch hook for a backrest adjustment armature in seats of motor vehicles, which hook is mountable rotatably on a part of the armature to lock and release it. The armature part is designed to pivot forward together with a part of the seat and to rest, when in a locked position, against a stop on a base frame of the seat. Force is exerted on the catch hook by a stored-energy device in the locking direction. The opening of the catch hook gripping behind the stop when in the locked position, where a tension latch, which also grips behind the stop when in the locked position, is arranged next to the catch hook. The latch itself is pivotably supported on the catch hook so that it can, as needed, be released from the locked position by an actuating element. The tension latch is connected to the catch hook by way of support elements so that it can move in advance of the catch hook in a direction of travel. Force in the locking direction is exerted only on the tension latch by a single stored-energy device. The catch hook is held in the locked position only by the working connection established by way of the support elements. A projection on the catch hook, which is in working connection with a stop bump on the armature part, limits the pivoting movement of the catch hook in the clockwise direction, and the catch hook is thus held in a position in which it is ready to travel past the stop.
