Window bracket for a window lift mechanism
View Patent ↗A dual rack and pinion system for a window lift mechanism includes window brackets for simple mounting to a window. The system includes a modular frame design to improve assembly of the window lift mechanism into the door of a vehicle. An assembly method is provided for the dual rack and pinion system. The system is also provided with a smart motor and incorporates resilient shock absorbers in the dual rack and pinion gear train to allow more time for the smart motor to detect and react to an obstruction in the window.
1. A closure assembly comprising:
a closure member;
a window bracket coupled to said closure member, said window bracket including a channel for receiving said closure member therein; and
a pair of metal plates disposed on opposite sides of said window bracket and including a clamping mechanism engaging each of said pair of metal plates for drawing said metal plates toward one another, wherein each of said pair of metal plates includes a bend generally bisecting the metal plate so as to be generally V-shaped and applies a clamping force to said window bracket on a respective side of said channel.
2. The closure assembly of claim 1 , further comprising a support member coupled to said window bracket and adapted to be driven for raising and lowering said closure member; and
an interface between said window bracket and said support member permitting axial and pivotal movement of said closure member with respect to said support member.
3. The closure assembly of claim 2 , wherein said interface includes a head portion on said support member which is slidably and rotatably received in a guide portion of said window bracket.
4. The closure assembly of claim 3 , wherein said head portion is semi-cylindrical and said guide portion is semi-cylindrical.
5. The closure assembly of claim 1 , wherein said window bracket includes a pair of recessed groove portions on each said side thereof for receiving opposite edges of a respective one of said pair of metal plates, said opposite edges of said pair of metal plates extending parallel to said bends.
6. The closure assembly of claim 1 , wherein said clamping mechanism includes a threaded screw extending through each of said metal plates.
