Abstract

A position detection unit is provided with a rotation member which rotates by the rotational driving force of an output shaft; an operation lever which is not engaged with the rotation member when the open or closed position of a window pane is at a location that does not belong to a dead zone region, which is engaged with the rotation member when the open or closed position of the window pane is at a location that belongs to a dead zone region, and which, when thus engaged, performs rotational operation by the rotational driving force of the output shaft, this force being transmitted via the rotation member; and a dead zone region detection switch which performs changeover operation on the basis of the rotational operation of the operation lever. The detection accuracy improves because the dead zone region is detected on the basis of rotational operation of the operation lever.

Description

technical field

[0001] The present invention relates to a window lifter for automatically opening and closing a window glass of a vehicle by power generated by a power source such as a motor. In particular, the present invention relates to a window lifter including an opening / closing position detection unit that detects whether the opening / closing position of a window glass falls within a predetermined specific position area. Background technique

[0002] The window glass attached to the side window, roof window, etc. of the vehicle has been opened and closed manually in the past, but until now, the window glass of most vehicles has been automatically opened and closed by power generated by a power source such as an electric motor. In the case of automatically closing the window glass, there is a concern that a foreign object may be caught between the window glass and the window frame. At present, a window lift device has been developed that has the following functions. Whe...
