Abstract:
1. A fitting for a vehicle seat, in particular for a motor vehicle seat, with an adjustment fitting for the inclination adjustment of a backrest of the vehicle seat relative to a seat part of the vehicle seat, a free-pivoting unit for the central free-pivoting of the backrest from at least one use position into a freely pivoted position about an axis (A), a fitting lower part which is a fitting part to be connected to the seat part and which bears the adjustment fitting, a free-pivoting part which is a fitting part assigned to the free-pivoting unit and which is to be connected to the backrest and which is locked in the use position, and a catch arrangement which is arranged pivotably on one of the fitting parts and fixes the free-pivoting part in the freely pivoted position of the backrest by means of interaction with a mating element formed on the other fitting part, wherein the catch arrangement has a pivot axis (B), the catch arrangement furthermore has a catch and a lever, which are pivotable relative to each other about an axis spaced apart from the pivot axis (B), the catch is of contoured design in the manner of a hook in an end region and is in engagement in a punctiform or linear contact region (C) with a catch locking element in the freely pivoted position of the backrest for locking purposes, and the catch, in particular the other end of the catch, interacts with a spring, the lever, in the region of a first end, is mounted pivotably about the pivot axis (B) and, in the region of its opposite, second end, rotatably supports the catch, wherein, in the unloaded, freely pivoted position, a perpendicular plane in the contact region (C) is located along one side of the pivot axis (B) or through the pivot axis (B), as a result of which a torque closing the catch is produced or no torque is produced and, when a pivoting-back force is applied to the backrest in the freely pivoted position, the perpendicular plane in the contact region (C) is located along the opposite side or outside the pivot axis (B), as a result of which a torque opening the catch is produced.
