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

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, wherein 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, wherein the spindle end is displaceably held on the first compensating element and the first compensating element together with the spindle end is displaceably held on the second compensating element.

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 rotatable spindle extending along a spindle axis and a spindle nut meshing with the spindle, wherein the spindle nut is fixed to an adjusting part adjustable by means of the spindle drive via a bearing point, wherein at the bearing point at least one elastic compensating element is provided, via which the spindle nut is held on the adjusting part such the spindle nut along with a portion of the spindle meshing with the spindle nut is displaceable at least along a spatial direction extending perpendicularly to the spindle axis by elastically deforming the compensating element.
