摘要： A catch hook for the releasable locking of the backrest connected with the seat part of a vehicle seat such that the backrest can swivel forward. The catch hook is supported in a swivelably articulated manner at the articulated part of an articulated fitting which possibly comprises an adjusting and locking arrangement for adjusting the inclination of the backrest, this articulated part being connected with the seat part so as to be swivelable. The hook jaw of the catch hook engages around a stop for the articulated part in the locking position, this stop being fixed to the seat part. The locking position is secured in a releasable manner by a retaining lever which acts on the catch hook and is supported at the articulated part so as to be swivelable. In order to minimize the structural component parts required for the catch hook arrangement, the catch hook has a control cam forming the upper side of the hook jaw and projecting beyond the hook finger. The catch hook is connected with the retaining lever by a force accumulator which acts on the latter so as to press them against one another. An operable releasing member is articulated at the retaining lever.
