Claims13
A brake booster pushrod to pedal interface cage comprising:
- a plurality of side walls;
- a front face connecting to each of the plurality of side walls at a first side of the plurality of side walls, the front face comprising a recess for receiving an end of a booster pushrod;
- and
- at least one weakened portion configured to allow the booster pushrod to move through the front face at a predetermined force, wherein the at least one weakened portion comprises one or more slits in the front face and/or the recess.
A brake pedal booster pushrod to pedal interface assembly comprising:
- a pivotable brake pedal arm comprising a foot pad disposed at a distal end of the pedal arm, and a brake booster pushrod to pedal interface cage comprising:
- a plurality of side walls;
- a front face connecting to each of the plurality of side walls at a first side of the plurality of side walls, the front face comprising a recess for receiving an end of an elongate booster pushrod;
- and
- at least one weakened portion configured to allow the booster pushrod to move through the front face at a predetermined force;
- a brake clip connecting to the brake booster pushrod to pedal interface cage;
- wherein the booster pushrod comprises a first end adapted to pivotably engage the recess of the brake booster pushrod to pedal interface cage;
- and
- one or more stops connected to the pedal arm and configured to receive the booster pushrod and stop further forward and/or sliding movement of the booster pushrod with respect to the pedal arm after the booster pushrod has moved through the front face of the brake booster pushrod to pedal interface cage.
A method of forming a brake pedal booster pushrod to pedal interface assembly, the method comprising:
- forming or obtaining a brake booster pushrod to pedal interface cage comprising a plurality of side walls and a front face connecting to each of the plurality of side walls, the front face comprising a recess for receiving an end of a booster pushrod and at least one weakened portion configured to allow the booster pushrod to move through the front face at a predetermined force, wherein the at least one weakened portion comprises one or more slits in the front face and/or the recess;
- connecting the brake booster pushrod to pedal interface cage to a pivotable brake pedal arm;
- and
- connecting the end of the booster pushrod to pivotably engage the recess of the brake booster pushrod to pedal interface cage.
