DOOR TRIM ASSEMBLY WITH CLUTCH MECHANISM

摘要

A door trim assembly comprises a handle coupler, spindle driver, clutch, motor, and clutch driver assembly. The clutch is configured to selectively engage and disengage the handle coupler to the spindle driver. When engaged, the spindle driver rotates with the handle. When disengaged, the handle rotates freely of the spindle driver. The clutch driver assembly includes an escapement spring positioned coaxially with the motor shaft and held between first and second spring seats. A motor is operable to rotate the first spring seat. The second spring seat carries a pin or cam to operate the clutch and is biased by legs of the escapement spring to rotate with the motor. If the second spring seat is blocked from rotating, then rotation of the first spring seat winds the escapement spring.
