Claim:
1. A stop mechanism for a drive system having a motor, a drive shaft rotated by the motor, and an output element driven by rotation of the drive shaft, the stop mechanism comprising: a first one-way clutch for coupling with the drive shaft for rotation with the drive shaft when the drive shaft is rotating in a first drive direction but not when the drive shaft is rotating in a second drive direction opposite the first drive direction; a first brake connected to the drive shaft by way of the first one-way clutch, the first brake being operable to stop rotation of the drive shaft in the first drive direction; a first stop feature carried by the output element for movement with the output element; and a linkage for connecting the first stop feature to the first brake; wherein the first stop feature actuates the linkage to operate the first brake to stop rotation of the drive shaft in the first drive direction when the output element reaches a predetermined first limit position when moving in a first driven direction corresponding to the first drive direction of the drive shaft.
