Abstract
Abstract A control system and method for operating an automobile window to provide anti-trap protection in an AUTO UP mode, wherein a switch assembly communicates switch signals representative of operator commands by disposition in distinct positions. A sensor that detects when an object is trapped between the window and the frame, and transmits an anti-trap signal representative thereof. A logic circuit receives the switch signals and the anti-trap signal and controls the drive assembly for the window in response thereto. The switch assembly includes a switch to override the anti-trap sensor for closing the window even when an obstruction is sensed during the closing operation.

Claim 4
Dependent Claim
61 words
The control system as defined in claim 1 wherein the first switch has detent positions corresponding to said distinct modes and wherein an AUTO UP detent for said AUTO UP mode with the anti-trap protection enabled is interposed between an OFF detent for said OFF mode and a MANUAL UP detent for said MANUAL UP mode with the anti-trap protection disabled.
Claim 5
Dependent Claim
28 words
The control system as defined in claim 3 wherein said MANUAL UP detent requires the operator to apply higher force to reach actuation than said AUTO UP detent.
Claim 6
Dependent Claim
32 words
The control system as defined in claim 4 wherein said first switch includes means for maintaining the first switch in the AUTO modes until returned to the OFF mode by the operator.
Claim 7
Dependent Claim
37 words
The control system as defined in claim 1 wherein the switch assembly includes an override switch for selectively disabling operation of the anti-trap protection when said first switch is disposed in said MANUAL or AUTO UP modes.
Claim 8
Dependent Claim
