A multi-way adjustment device, in particular a two-way adjustment device, is proposed for a seat component, which is suitable in particular for the seat-back width adjustment of a seat. The multi-way adjustment device comprises an adjustment part () adjustably mounted relative to a mounting plate a (), which when moved in a first adjustment direction (A) requires less energy expenditure than when moved in a second adjustment direction (B). In order to compensate this, there are provided mechanical energy accumulation means (), which takes up mechanical energy when the movement is in the first adjustment direction (A), in order to release this when the movement is in the second adjustment direction (B) and thus to assist the movement of the adjustment part () in the second adjustment direction (B). Moreover, the invention relates to a corresponding adjustment device for a cable, in particular a Bowden cable, in order, for example, to adjust a lumbar support for a seat with respect to curvature or height position.

Multi-way adjustment device for a seat component and/or a cable

An adjuster is proposed for the vertical adjustment of a head restraint () of a seat (), said head restraint being equipped with adjustment means () movable in an adjustment direction (A) which are formed in such a manner that it can engage with a head restraint (), that can be inserted into the head restraint holder, whereby drive means () for producing an adjustment movement of the adjustment means () are additionally provided. The drive means () in this case form a unit spatially separate from the head restraint holder. The adjustment movement of the drive means () in this case is transferred to the adjustment means () by flexible transmission means (), such as, for example, a flexible shaft or a Bowden cable. As a result, the drive unit () can be placed independently of the head restraint holder.
