A unitary, light-weight, and readily installable shock absorbing device for use in conjunction with the seat of a bicycle provides a pair of interacting, open-ended housings which are held together in variable linear relationship by a pair of bolt-like fasteners. A plurality of coil springs are disposed internally of the housing and serve to separatably urge the housings in the direction of their maximally extended positions and a plurality of coil springs are also disposed exteriorly of the lower of the housings and serve to retard the abrupt separation of the housings caused by the internally disposed springs when the latter springs are compressed by the weight of a rider. The interaction of the open ends of the housings permit the internally disposed springs to contract and expand without transmitting or permitting forward or sidewise sway or shift to the seat of the bicycle. Auxillary coil springs of shorter linear dimension are also disposed internally of the housings and coaxially arranged relative to the longer springs thereof to enhance the cushioning effect of the shock absorbing device when a rider of relatively heavy weight is seated on the seat of the bicycle.

A shock absorbing device for use in association with the seat of a bicycle or the like comprising: (a) a first housing adapted for receiving a saddle-like seat, said first housing being rectangularly cubical in configuration and presenting four sidewalls defining an open end and a closed end, (b) a second housing adapted for attachment to the frame of a bicycle, said second housing being rectangularly cubical in configuration and presenting four sidewalls defining an open end and a closed end, (c) resilient securing means effective for cushionably securing said first and said second housings in predetermined variable colinear and interacting relationship as the wheels of said bicycle are subjected to shock of varying intensity, said securing means comprising a first set of coil springs internally disposed of said housings and abutting against said closed ends thereof, a second set of coil springs exteriorly disposed of said second housing and abutting against the closed end thereof, and a third set of coil springs internally disposed of said housings and coaxially arranged relative to predetermined ones of said first set of coil springs, and (d) means associated with said sidewalls of said first and said second housings effective for preventing lateral and longitudinal motion of the seat relative to the bicycle as might otherwise be permitted by the resilient nature of said resilient securing means and caused by the normal forces experienced by a rider during his use of the bicycle.
