ABSTRACT:
The lifting device for a vertically adjustable front cushion of a vehicle seat comprises a support structure with first and second vertically extending flanges on either side. The first flanges have a fixedly connected first pin and the second flanges have a fixedly connected bearing with a rotatable second pin. The support armature of the front cushion has on either side a third and a fourth pin. First connecting rods are pivotably connected with the first and third pins. Each first connecting rod has a fifth pin between the first and third pin. Second connecting rods are pivotably connected with the second and fourth pins. Curved plates with a cutout are pivotably connected to the fifth pins. A horizontal S-shaped lever is pivotably connected with its center to the support structure. A fork is connected with a lug to the rear end of the S-shaped lever. A stud is connected to the support structure. Arms are fixed to the second pins, and a transverse stay connects their free ends. A control handle is connected to one of the second pins. When the front cushion is lifted, the cutouts engage the second pins and one rear end of the curved plates pivots the lever and displaces the fork into locking engagement with the stud for latching the front cushion in the upper position. For releasing the front cushion, by turning the control handle the transverse stay is rotated upwardly to disengage the cutouts and release the fork.
