Catch hook for a backrest adjustment armature in the seats of motor vehicles

A catch hook for a backrest adjustment armature in seats of motor vehicles, which hook is mountable rotatably on a part (13) of the armature to lock and release it, the armature part (13) being designed to pivot forward together with a part of the seat and to rest, when in a locked position, against a stop (15) on a base frame of the seat, force being exerted on the catch hook by a single stored-energy device in the locking direction via a tension latch (22, 22′), the opening (20) of the catch hook gripping behind the stop (15) when in the locked position, where the tension latch (22, 22′), which also grips behind the stop (15) when in the locked position, is arranged next to the catch hook (18), the latch itself being pivotably supported on the catch hook (18) so that it can, as needed, be released from the locked position by an actuating element (28), and where the tension latch (22, 22′) is connected to the catch hook (18) by way of support elements (24, 26;

• 36, 37) in such a way that it can move in advance of the catch hook in a direction of travel, wherein
• force in the locking direction is exerted only on the tension latch (22, 22′) by the single stored-energy device (31);
• the catch hook (18) is held in the locked position only by the working connection established by way of the support elements (24, 26;
• 36, 37);
• and
• by means of a projection (33) on the catch hook (18), which is in working connection with a stop bump (34) on the armature part (13), the pivoting movement of the catch hook (18) is limited in the clockwise direction, and the catch hook (18) is thus held in a position in which it is ready to travel past the stop (15).
