Abstract
A window lift mechanism for raising and lowering a window in a vehicle door includes a support bracket mounted to the window and a motor supported on the support bracket, wherein the support bracket permits the axial and rotational movement of the window relative to the support bracket. A pair of parallel, vertical racks are mounted to the door and are positioned immediately adjacent to the window. A worm gear is driven by a worm with a lead angle greater than seven degrees coupled to a motor. A clutch mechanism is utilized to prevent back drive of the worm/worm gear system. The worm gear is operatively coupled to a pinion gear with resilient shock absorbers that are provided with notched surfaces to accommodate for compression of the resilient material with an enclosed space.
Claims21
A window lift mechanism comprising:
- a support structure;
- a pinion gear supported by said support structure;
- a worm gear supported for rotation by said support structure and operatively joined with said pinion gear;
- a motor supported by said support structure and including an output shaft having a worm engaged with said worm gear;
- and
- a resilient shock absorber operatively engaged between said pinion gear and said worm gear and having surfaces with notched portions to allow for deformation of said resilient shock absorber.
A window lift mechanism comprising:
- a support structure;
- a pinion gear supported by said support structure;
- a first worm gear supported for rotation by said support structure and drivingly engaged with said pinion gear;
- a motor supported by said closure member and including an output shaft having a worm with a lead angle greater than seven degrees and engaged with said worm gear;
- and
- a clutch mechanism disposed between said worm gear and said pinion gear to prevent back-drive.
A window lift mechanism comprising:
- a support structure;
- a pinion gear supported by said support structure;
- a worm gear supported for rotation by said support structure meshingly engaged with said pinion gear;
- a motor supported by said support structure and including an output shaft having a worm engaged with said worm gear;
- and
- a clutch mechanism disposed between said worm gear and said pinion gear.
A closure assembly comprising:
- a closure member;
- a first support coupled to said closure member;
- a second support coupled to said first support and adapted to be driven for the raising and lowering of said closure member;
- and
- an interface between said first and second supports permitting axial and pivotal movement of said closure member with respect to said second support.
A closure assembly comprising:
- a closure member;
- a first support coupled to said closure member;
- a second support coupled to said first support and adapted to be driven for the raising and lowering of said closure member;
- and
- said first support having a slot in which said closure member is received and an interface between said first and second supports including a protrusion and a channel;
- wherein said interface permits axial and rotational movement of said first support with respect to said second support.
