Patent attributes
A resistance mechanism used in motor vehicle accelerator pedals for generating an opposing mechanical force. The resistance mechanism includes a piston adapted for movement in a housing between a first detent or stop position and a second compressed position. The piston includes an exterior surface defining at least one recess. A spring, located in the housing, biases the piston in the first position. A pin in the housing is seated in the recess of the piston in the first position of the piston. A retainer is adapted to retain the pin in the piston recess in the first position of the piston. The piston is adapted for movement between the first position and a second compressed position in which the pin is forced out of the recess and into the housing.
