摘要

The invention relates to an adjusting device, in particular a height or longitudinal adjusting device for motor vehicle seats, comprising a threaded spindle that is rotatably mounted in a gearbox housing at one end and in a receiving unit at the other end, said receiving unit having an inner thread that is adapted to the spindle thread. The adjusting device also comprises a motor unit that is operatively connected to the threaded spindle. The aim of the invention is to provide an adjusting device and a seat base frame for motor vehicle seats with an adjusting device that transmits forces that occur in the event of a crash to the required degree. This is achieved in that a reinforcing element is provided in the gearbox housing such that said element is suitable for receiving forces that act in the longitudinal axial direction of the threaded spindle in the event of a crash.
