A lead screw nut support arrangement includes a wall having a width and a through hole that passes through the wall. A support bushing passes through the through hole in the axial direction, leaving an amount of play, and having a length greater than the thickness of the wall. The support bushing is supported in the through hole movably in the axial direction. A lead screw nut is also included whose end face adjoins a first end face of the support bushing on the inner side of the wall. The support arrangement also includes a mount that braces a second end face of the support bushing against the lead screw nut such that the lead screw nut is elastically loaded in the direction away from the wall.

Lead screw nut support arrangement

The invention relates to a drive for adjusting motor vehicle seats comprising a spindle () fixed to a first () of two rails () which are adjustable with respect to each other with the aid of holding devices () arranged on the end of the spindle (). A transmission () actuated by a motor () is placed on the second rail (), According to id invention, the holding devices () comprise an external bowl-shaped supporting surface () in which each end of the spindle () is fixedly mounted, respectively. Said solution is more advantageous in comparison with conventional holding devices which are embodied in the form of flexible stamped parts, in particular the inventive holding devices exhibit a high resistance in the case of crash.
