Back-rest hinge for a vehicle seat with a seat support and a back-rest hinged to it

摘要

The back-rest hinge is intended for a vehicle seat with a seat support (20) and a back-rest, which is hinged to this support by means of a swivel joint (shaft 28), and a locking mechanism (44 to 58) for adjusting the angle of inclination of the back-rest (30) in relation to the seat support (20). A locking lever is hinged to the back-rest at a hinge point which is at a distance from the swivel joint along the lengthwise direction of the back-rest (30). The locking lever (38) has a locking area which extends in the direction of the seat support (20) and toward a front edge of this seat support. On the seat support (20) an interlock assembly is provided which interacts with the locking area, can be released, and is normally in mesh (locking lever 52), and with which an activating member is associated (activation lever 56).
