Patent ID: 8136882

Claim:
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.
