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

摘要

A back-rest hinge for a vehicle seat that has a seat support and a back-rest. The back-rest hinge has a swivel joint operatively interconnecting the seat support and the back-rest for variable inclination of the back-rest relative to the seat support. A locking mechanism permits adjusting an angle of inclination of the back-rest in relation to the seat support. A locking lever is hinged to the back-rest at a hinge point spaced from the swivel joint along a lengthwise direction of the back-rest. The locking lever has a locking portion which extends from the hinge point in a direction of the seat support that intersects a front edge of this seat support. The locking mechanism includes an interlock mechanism on the seat support, which interacts with the locking portion, and an activation device. The interlock mechanism is positionable between one position in which it is cooperatively engaged with the locking portion and another position in which it is disengaged from the locking portion. The activation device can releasably retain the interlock mechanism in the one position. The back-rest hinge further has an adjustment device disposed between the swivel joint and one of the back-rest and the seat support. This adjustment device has a direction of adjustment that essentially extends in parallel to the previously-mentioned direction of the seat support.
