Abstract
A window actuating system, especially in a motor vehicle, including a guide rail, an entrainment device for a window glass plate supported at the guide rail, a force transmission member engaging at the entrainment device, a drive member for the force transmission member attached to the guide rail and selectably with a manual drive unit arranged to be remote from the guide rail or a motorized drive unit coupled with the drive member, the drive member being provided with a reverse brake, especially a wrap around spring brake, and the motorized drive unit being attached directly at the drive member or at the drive rail in the region of the drive member.
Claims16
A window actuation system, especially in a motor vehicle, comprising:
- a first guide rail (20;
- 320);
- a first entrainment member (26;
- 326) for a window glass plate (30;
- 330) supported at the guide rail (20;
- 320) so as to be movable in its longitudinal direction (A);
- a force transmission member (22) engageable at the first entrainment member (26;
- 326) and guided so as to be mobile parallel to the longitudinal direction (A) of the first guide rail;
- a drive member (18) for the force transmission member (22) attached to the first guide rail (20;
- 320);
- and
- drive means for driving the drive member (18), said drive means selectively including a manual drive unit (12) arranged remotely from the guide rail (20) and connected with the drive member (18) by a torque transmission member (14;
- 52), and a motorized drive unit (46;
- 346) coupled with the drive member (18) so as to be able to transmit force, the drive member (18) having a wrap around spring brake (42;
- 342), and the motorized drive unit (46;
- 346) being directly attachable to one of the drive member (18) and the guide rail (20;
- 320) in the region of the drive member.
