Provided is a retainer for assisting in installation of a parking brake actuator for use in a vehicle by limiting relative movement of an input lever and a mounting bracket. The retainer has a first part and a second part connected via frangible connection(s). The first part of the retainer is fixed relative to a mounting bracket and the second part is fixed relative to the input lever (via a pivot member). After installation, the lever is moved from its first, installation position to a second, in-use position. The application of force and movement of the lever rotates the pivot member, which rotates the second part of the retainer relative to the first part thereby breaking the frangible connection(s). The input lever of the brake actuator is then ready for use to apply or release brakes of the vehicle.

A brake actuating system in a motor vehicle having wheels and brakes for braking rotation of the wheels includes a cable system including a plurality of cables operatively connected to the brakes of the vehicle. An actuator is operatively connected to the cable system and is operable by an occupant of the vehicle for movement between applied and released positions to selectively increase and decrease the tension in the cables of the cable system to thereby activate and deactivate the brakes of the vehicle, respectively. A cable tensioner including a rotary input member is selectively and adjustably coupled to an input side cable of the cable system. The input member is rotatable in tensioning and releasing directions. The input side cable includes a retaining structure that prevents disengagement of the input member from the input side cable when the input member is rotated in the releasing direction.

Device and method for pre-stressing the cable system of a vehicle brake actuating system

A parking brake actuator for a vehicle includes a toothed stationary sector fixed to a mounting structure, a brake lever pivotably mounted to the sector, a pawl mounted to the brake lever for movement between engaged and disengaged positions relative to the teeth, an elongated, substantially rigid release member mounted to the brake lever for movement relative to the brake lever between normal and depressed positions, and a motion-absorbing member connecting the release member to the pawl. When the brake lever is operatively connected to the vehicle brake cable and in a braking position thereof with the pawl in the engaged position thereof, moving the release member to the depressed position thereof without also moving the brake lever in the brake applying direction compresses the motion-absorbing member without moving the pawl from the engaged position thereof.

Safety release feature

The present invention provides for a brake actuator for use in a motor vehicle. In a motor vehicle with one or more brakes activated by a cable system, there is a mounting bracket mounted in the motor vehicle. Movably mounted to the mounting bracket is a lever that can move in brake applying and brake releasing directions, and which is constructed to be connected to the brake cables. The lever applies tension to the brake cables when the lever is moved in the brake applying direction, and releases the tension when moved in the releasing direction. Mounted to either the lever or the mounting bracket is a retainer constructed to engage the other of the lever or the mounting bracket. The retainer acts to restrict the relative lateral movement of the lever and the mounting bracket.
