ADJUSTING DEVICE OF A LUMBAR SUPPORT OR OF A SIDE-BOLSTER ADJUSTER HAVING A SPINDLE DRIVE FOR A SEAT ELEMENT OF A VEHICLE SEAT

摘要

The invention relates to an adjusting device of a lumbar support or of a side-bolster adjuster for changing the contour or position of a seat element (S) of a vehicle seat, which seat element supports a body part of a seat user, comprising at least one drive apparatus (4a, 4b), which comprises a spindle drive, and comprising at least one adjustable support element (20, 21) for changing the contour or position of the seat element (S), the spindle drive comprising a spindle (5), which extends along a spindle axis (SA) and which, at a fastening part (B) of the lumbar support or of the side-bolster adjuster, which fastening part is intended for mounting in the vehicle seat, is mounted in a floating manner at a spindle end (50) by means of a spindle holder (7, 7') in such a way that the spindle (5) can be moved at said spindle end (50) in at least one spatial direction (x, y) extending transversely to the spindle axis (SA). According to the invention, the spindle end (50) is retained at the fastening part (B) of the lumbar support or of the side-bolster adjuster by means of the spindle holder (7, 7') for movement with respect to two spatial directions, a first and a second spatial direction (x, y), which extend approximately perpendicularly to each other and perpendicularly to the spindle axis (SA).
