Abstract: A window winder drive functions with a freewheeling coupling, which has an outer coupling part and an inner coupling part, which is concentric thereto, and comprises clamping bodies arranged between a clamping face of the outer coupling part and a clamping face of the inner coupling part, wherein the clamping bodies are arranged in pairs in the annular space formed between the clamping faces, and the first clamping body of a pair of clamping bodies demonstrates a clamping effect exclusively in a specific direction of rotation of the outer coupling part in relation to the inner coupling part, while the second clamping body of the pair of clamping bodies exclusively has a clamping effect in the opposite direction of rotation.

Abstract: A compact door check of modular design for a vehicle door is described that can be integrated in the door hinge and mated with many types of hinges and door assemblies. The door check according to the invention is includes a housing affixed to a first half of the door hinge, a shaft extending through the housing and connecting the other half of the door hinge to the first half to allow the first half to rotate about the shaft, and a detent mechanisms defining a plurality of detent positions of the door hinge. The detent mechanism is enclosed in the housing so as to be sealed against the environment to prevent contaminants and debris from affecting the operation of the door check.
