Abstract
A shock-absorbing and height-adjusting assembly for mounting a seat onto the seat-supporting framework tubing of a bicycle frame. A standard, commercially available, adjustable-length gas spring (hydropneumatic spring), of the type used for the control column of adjustable height chairs, is slideably contained within a hollow receiver attached alongside or within a lower portion of the bicycle seat supporting framework to which the gas spring piston rod is affixed with the upper end of the gas spring in underlying contact with the lower end of a vertically extending elongated cylindrical seat supporting guide tube supported in alignment with the gas spring for axial and non-rotational movement within a bushing assembly affixed to the uppermost portion of the bicycle seat supporting framework. A push rod slideably contained within a longitudinally extending bore within the guide tube for vertical movement between a raised position with the push rod lower end overlying a top mounted gas spring actuator and a lowered position in operational contact with the gas spring actuator. The push rod being operable through flexible shafting connected to a hand-operated control mounted on the bicycle handlebars in which movement of the hand control raises and lowers the push rod into and out of actuating contact with a gas spring actuator as establishes the gas spring into various length and locking modes commensurate with the weight loading applied on the bicycle seat.
