The invention concerns braking systems for vehicles. The invention provides one, or more, electrically actuated pressure generators, which provide hydraulic pressure for actuating hydraulic brakes. Electric actuation allows control by electronic signals, which are generated by a microprocessor-based controller. The pressure generators can be retro-fitted to existing hydraulic brake cylinders. The controller may be incorporated into, or operate in conjunction with, the on-board engine computer.

Vehicle brake

A reverse to park mechanism of the type in which a crank arm is eccentrically pivoted relative to a reversable drive shaft axis. The crank arm is held in a first position by a drive lug on one side of the crank arm that prevents it from pivoting in one direction, and a latching lever pivoted to the crank arm that engages a latching pin to prevent it from pivoting in the other direction. The orientation of a keeper surface of the latching lever relative to the cylindrical surface of the latching pin that it contacts is designed to provide a very strong resistance to slip off, while allowing a reversal activated torque means to easily move the keeper surface off of the latching pin to release the crank arm.

Reverse to park mechanism with secure latching

A power door lock actuator includes a one piece molded and centrifugally expandable brake ring that is held on a drive ring to a motor shaft within a lock lift arm driving cup that is freely pivoted to the shaft. A camming member on the drive ring fits within the brake ring so as to retain it to the shaft, to maintain it in a ready position spaced from the cup when stationary, and so as to jam it into the wall of the cup when turning.

Clutch for power door lock actuator

An automobile door latch has a fork-type latch bolt, a detent lever which automatically retains the bolt in a closed-latched position in a manual-closed operating mode of the latch when the door is manually swung to the closed position, a manually actuated release lever which moves the detent lever to a releasing position releasing the bolt in a manual-open operating mode of the latch, and a power operating means which power rotates the bolt from an ajar-latched position to the closed-latched position in a power-closed operating mode of the latch and which moves the detent lever to the releasing position in a power-open operating mode of the latch. The door latch further includes an electrical control which automatically actuates the latch in the power-closed operating mode when the latch bolt achieves the ajar-latched position and which permits random sequencing of the manual and the power operating modes of the latch.

Power operated door latch

An energy absorbing coupling for use with an electric motor-driven window regulator mechanism, including a torsion spring arrangement between an input gear and an output pinion which provides (1) a driving connection in either direction, and (2) a relative movement or lost-motion connection for absorbing the energy generated by the inertia of the electric motor armature when the window reaches its limit of movement in one direction of the other.
