Abstract

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 (7) adjustably mounted relative to a mounting plate a (1), 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 (5), 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 (7) 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.

Dependent claims

Multi-way adjustment device for adjusting a rest width of a seat, the multi-way adjustment device comprising

a mounting plate,
an adjusting part which is mounted so as to be displaceable relative to the mounting plate and is to be coupled with a rest portion of the seat, whereby the adjusting part is of an elongate design with a middle portion disposed between a first end portion and a second end portion with the first end portion having a bigger width than the middle portion, the adjusting part being mounted so as to be displaceable on the mounting plate by means of the middle portion, and
an adjusting unit for displacing the adjusting part relative to the mounting plate in a first adjustment direction and a second adjustment direction, whereby one of the first and second adjustment directions is for reducing the rest width and the other of the first and second adjustment directions is for increasing the rest width,
whereby the adjusting part is coupled with mechanical energy storage means in such a way that, when the adjusting part is displaced in the first adjustment direction relative to the mounting plate, mechanical energy is absorbed by the mechanical energy storage means, whereas a displacement of the adjusting part in the second adjustment direction relative to the mounting plate is assisted by the release of the mechanical energy previously absorbed by the mechanical energy storage means.
