Booster control rod coupling arrangement

摘要

An arrangement ( 10 ) for disconnectably coupling an axially orientated motor vehicle brake booster control rod ( 12 ) to a brake pedal ( 14 ). A first end ( 16 ) of the control rod ( 12 ) is coupled to an intermediate part ( 20 ) of a vertical actuating bar ( 22 ) of the brake pedal ( 14 ). The first end ( 16 ) has a head ( 32 ) with at least one spherical bearing surface ( 34 ) that is housed in a complementary boss ( 36 ) formed in a wall of the intermediate part ( 20 ). The head ( 32 ) is kept in contact with the boss ( 36 ) via elastically deformable axial retention means ( 38 ) interposed between the intermediate part ( 20 ) of the actuating bar and the control rod ( 12 ). The deformation is controlled by an unlocking arrangement ( 52 ) that accessible from outside of the intermediate part ( 20 ) of the actuating bar ( 22 ).
