Abstract

A manual adjustment of a back support on a vehicle seat includes a cable pulley which is selectively rotatable in a drive direction or in a driven direction oriented counter to the drive direction, and a tensile device associated with the cable pulley, which may be rolled up onto the cable pulley by rotating the cable pulley in the drive direction. The tensile device is able to be coupled to a back support of a vehicle seat such that the rotation of the cable pulley in the drive direction and/or driven direction affects an adjustment of the back support. A pretensioning acts on the cable pulley -which produces a torque of the cable pulley in the driven direction.
