ABSTRACT:
Lumbar support and control device of a lumbar support and method for controlling a lumbar support of a motor vehicle. An electric control device is provided for a lumbar support which has a drive coupled mechanically to an adjusting mechanism for setting the seat contour of the lumbar support. The control device has at least one computer unit which controls a massaging movement of the lumbar support whereby the massaging movement is characterized through several predefinable ideal speeds. Several ideal speeds for one or more adjusting directions of the lumbar support are controllable through the computer unit. For control by the ideal speeds a drive moment of the drive is adapted to an actual load of the drive so that the massaging movement can be controlled substantially independent of the actual time-changeable or locally variable load. The drive moment is consequently changeable through the control device.
