Multiple adjustment devices drive unit with electromotor - has inner drive shaft selectively connectable to different adjustment device coupling elements

摘要

The drive unit has an electromotor (2) and actuates several different adjustment devices and axially movable coupling elements, especially for two adjustment devices of a vehicle seat. The electromotor (2) has a motor shaft (20). This has a hollow outer shaft (21) and a removable, non-rotatable inner shaft (22) connected inside it. The latter is selectively, non-rotatably connected to appropriate coupling elements (41, 42) of the selected adjustment device by means of coupling elements (23', 24') on the motor side. USE/ADVANTAGE - For vehicle seats. A compact, light and simple device with high power and high precision.
