Apparatus for monitoring the closing of a window by an electric motor, particularly a window of a motor vehicle

摘要

An apparatus for monitoring the closing of a window by an electric motor, particularly a window pane of a motor vehicle, has a sender and a receiver for electro-magnetic transmissions and at least one light-deflecting mechanism which guides electro-magnetic emissions, or waves, from the sender to the receiver. The apparatus can be used in conjunction with devices for stopping or reversing motion of the window pane if during the closing thereof the transmission intensity received at the receiver changes, the light-deflecting mechanism being arranged along at least portions of an upper edge of a window opening.
