Abstract: A patient support incorporates a patient retention device includes frame, a rotatable shaft, a torque-producing device, and a flexible restraint member. The shaft has a cantilevered portion that extends from the frame and windably receives the flexible restraint member at the cantilevered portion. Optionally, a winding member is releasably coupled to the cantilevered portion of the shaft for receiving the flexible restraint member. The winding member is non-rotatable relative to the shaft, and is readily removable and replaceable. The torque-producing device applies a torque to the shaft to wind the flexible restraint member onto the shaft or winding member.
