ABSTRACT:
A fitting for vehicle seats, particularly motor vehicle seats, includes an adjustable fitting component connected to the back rest of the seat and a stationary fitting component at the seat portion, wherein the stationary fitting component is mounted at its front end so as to be pivotable about an axle pin rigidly connected to the seat portion, and wherein the rear end portion of the stationary fitting component rests on a stop pin rigidly attached to the seat portion. In the locked position of the stationary fitting component, the stop pin is surrounded by the jaw of a catch hook mounted on the stationary fitting component, wherein the locked position is releasably secured by a locking device. The locking device includes an eccentric tensioning member which supports the catch hook in the locked position and is supported on a pin of the stationary fitting component, and a gear plate which is mounted on the eccentric tensioning member and surrounds the pin with an oblong hole. The gear plate has a control cam which over portions thereof interacts with a support pin of the stationary fitting component and to which is hinged a pull member which acts in a releasing direction against the force of a retaining spring. The eccentric tensioning member has a locking projection which faces the catch hook. In the open position of the catch hook, the locking projection engages in a recess provided on the catch hook and, in this position, the locking projection is held by a retaining spring extending between the gear plate acting on the eccentric tensioning member and the catch hook. The catch hook has an actuating projection protruding beyond the jaw of the catch hook for releasing the open position when making contact with the stop pin rigidly connected to the seat portion during the backward swinging movement of the back rest.
