Abstract: A supporting device for a seat, in particular a vehicle seat, has at least one planar supporting part and a plurality of fastening structures arranged on the supporting part. The supporting part has at least one region of extent for an extent in at least one direction in the surface plane of the supporting part. The supporting part is of planar design and has web-like surface sections. The at least one region of extent is designed as a predetermined separating point in at least one web-like surface region.

Abstract: A device for adjusting the position of a seat, in particular of a vehicle seat, has at least one fixing device for securing the position of the seat, which device has at least one locking element, each of which, in the locking position thereof locks at least two guide parts of the device to each other, which are held such that they can move in relation to each other, wherein at least one traction mechanism, with which the locking element can be moved out of the locking position thereof, is coupled to the locking element. A preloading element is associated with the traction mechanism, which preloading element acts directly on a section of the traction mechanism and preloads the traction mechanism without play.
