Abstract:
1. A brake actuation assembly for a vehicle, the brake actuation assembly being actuatable to apply and release tension to one or more elements that connect to a brake system of the vehicle, the brake actuation assembly comprising: an electrically powered brake actuator including a reversible motor with a driveshaft for driving connection with the one or more elements, the reversible motor being actuatable to rotate the driveshaft in a brake-applying direction to apply tension to the one or more elements and in a brake-releasing direction opposite the brake-applying direction to release tension to the one or more elements; a manually operable control for transmitting a signal to the motor to selectively operate the motor; and a manual brake actuator including a rotatable input member and a flexible cable, the manual brake actuator being movable between (a) an operative position wherein the cable connects the input member to the driveshaft to enable rotation of the input member to rotate the driveshaft in the brake-applying and brake-releasing directions via the cable, and (b) an inoperative position wherein the input member is disconnected from the driveshaft; wherein the driveshaft of the motor includes a first cooperating interlocking structure and the cable has a second cooperating interlocking structure, the manual brake actuator being movable between the operative position wherein the second cooperating structure of the cable is engaged in rotational interlocking relationship with the first cooperating interlocking structure of the reversible motor to enable the rotation of the driveshaft by the input member and the inoperative position wherein the second cooperating interlocking structure is disengaged from the first cooperating interlocking structure.
