Drive unit for movable parts of a vehicle roof assembly

摘要

A drive unit for closures for selectively opening and closing at least one roof opening in a roof assembly comprises an electric motor (14) having a drive shaft (16) and transmission means (15). The transmission means is a planetary gear mechanism and has at least two output shafts (12,13) and a switch mechanism including a locking member (23) in order to selectively allow one output shaft to be driven by the electric motor and to lock the other output shaft. <??>The invention provides a drive unit which is very functional but nonetheless comprises only one drive motor and is therefore compact and cost effective. <IMAGE>
