Embodiment Construction

[0023] FIG. 2 shows the right backrest side part 2 (backrest structure, backrest beam) of a backrest 3 (not further shown) of a motor vehicle seat 1 . The backrest side part 2 or the entire backrest 3 is connected via an adjustment collar attachment 4 to a seat frame 6 , here indicated by its right-hand outline in dashed lines. The adjustment collar attachment 4 can, for example, adjust the backrest angle around the backrest axis A in a comfortable swing range, and after the backrest is unlocked, the backrest 3 can be folded forward into a functional position, which can be particularly easy. The entry position is used to make the rear seats more accessible.

[0024] The seat frame 6 is fixed on an upper rail 8 which is longitudinally adjustable relative to the lower rail 9 to be fixed on the vehicle body and can be locked in its longitudinal position by a longitudinal locking device 10 . The right and left seat longitudinal locking devices 10 are coupled to one another, for e...

Abstract

The invention relates to an unlocking mechanism for a vehicle seat longitudinal locking system, wherein the unlocking mechanism comprises: an unlocking lever for releasing the seat longitudinal locking system, a cable drive (14) for controlling the unlocking lever, and a synchronous driver system (18) which comprises an active synchronous driver means (30), which is provided on a backrest structural part (2), and a passive synchronous driven means (26) connected to the cable drive (14), wherein the passive driven means (26) cannot be driven along when the backrest structural part (2) is pivoted into the upright use position thereof within a first pivoting range, and can be driven along by the active driver means (30) when the backrest structural part (2) is folded forwards beyond the first pivoting range, thereby producing a pulling action to pivot the unlocking lever and thereby unlocking the seat longitudinal locking system.

Description

technical field [0001] The invention relates to an unlocking device for a seat longitudinal locking device of an automobile seat. Background technique [0002] For the longitudinally adjustable car seat, the seat frame is generally fixed on the upper guide rail, and the upper guide rail can be adjusted longitudinally relative to the lower guide rail on the side of the vehicle body. A suitable longitudinal position can be locked or secured by the seat longitudinal locking device, so that the seat longitudinal locking device can first be released for subsequent longitudinal adjustment. [0003] In addition to manual unlocking, automatic unlocking is also known, so that, for example, in an easy-access adjustment, longitudinal unlocking can be automatically achieved by folding the backrest forward. [0004] EP0 878 344 A2 describes a seat longitudinal adjustment device, wherein a pin is provided on the backrest, which pin rests on a lever mechanism arranged on the axis of the b...
