It is provided an adjusting device for a seat element of a vehicle seat supporting a body part of a seat user, with at least one driving device comprising a spindle drive and at least one adjustable support element for changing the contour or position of the seat element, wherein the spindle drive comprises a spindle extending along a spindle axis, which is floatingly mounted at a spindle end via a spindle holder such that at this spindle end the spindle is displaceable along at least one spatial direction extending transversely to the spindle axis. The spindle holder comprises a first and a second compensating element for a displaceability of the spindle end with respect to two first and second spatial directions extending approximately perpendicularly to each other and each perpendicularly to the spindle axis.

Adjusting device having a spindle drive for a seat element of a vehicle seat

It is provided an adjusting device for a seat element of a vehicle seat, the strength structure of said seat element being connected to a guide device which substantially oriented in a first spatial direction and on which a support and a slide are arranged in a longitudinally adjustable manner relative to each other by means of a first drive device. A support lever which changes the contour of the seat element and which is hinged to the support and a toggle lever which is hinged to the slide and to the support lever via a connection joint are pivotable about axes which are oriented in a second spatial direction running perpendicularly to the first spatial direction and pivot on a plane defined by the first spatial direction and a third spatial direction running perpendicularly to the first and second spatial direction when the first drive device is actuated.

Adjusting device for a seat element of a vehicle seat

It is provided an adjusting device of a lumbar support or a side-bolster adjuster for changing the contour or position of a seat element of a vehicle seat supporting a body part of a seat user, with at least one driving device comprising a spindle drive and at least one adjustable support element for changing the contour or position of the seat element, wherein the spindle drive comprises a spindle extending along a spindle axis, which on a fastening part of the lumbar support or the side-bolster adjuster mounted in the vehicle seat is floatingly mounted at a spindle end via a spindle holder such that at this spindle end the spindle is displaceable along at least one spatial direction extending transversely to the spindle axis.
