Abstract
Abstract This invention relates to bicycle and tricycle seat posts and more particularly to shock-absorbing seat posts. This unique device, which fits in place of the conventional rigid seat post, supports the rider and absorbs all shock produced from traversing over small bumps, holes, etc., in the road. Another unique feature is that the seat is allowed to swing slightly from side to side, which not only produces a comforting effect, but also increases peddling efficiency.

Claim 1
Independent Claim
299 words
A shock absorbing seat assembly for use on a bicycle or the like, said assembly comprising an upright cylinder, a seat unit mounted on said cylinder and comprising a seat member and a rod secured to and extending downwardly from said seat member, said rod being telescoped within said cylinder for up and down movement therein, spring means in said cylinder engaged with said rod and urging said rod and said seat in an upward direction, bearing means supporting said rod in said cylinder during up and down movement of said rod in said cylinder, and position stabilizing means for said seat connected to and extending between said seat unit and said cylinder to prevent rotation of said seat unit relative to said cylinder wherein said position stabilizing means comprises a flat band member connected to and extending between said seat unit and said cylinder, said band member preventing rotation of said seat unit relative to said cylinder and offering minimal resistance to said up and down movement of said rod in said cylinder, and wherein said bearing means comprises a bearing unit having a sleeve with a plurality of holes formed therein, ball being rotatably mounted in each of said holes, said balls extending from said sleeve, said sleeve encircling said rod so that said balls engage said rod and said cylinder during up and down movement of said rod in said cylinder, and wherein said flat band member is flexed between said connections to provide said minimal resistance to the up and down movement of said rod in said cylinder and wherein said spring means is fixedly secured at its distal ends to said rod and to said cylinder, coacting with said flat band member to yieldably prevent rotation of said seat unit relative to said cylinder.

A shock absorbing seat assembly for use on a bicycle or the like, said assembly comprising an upright cylinder, a seat unit mounted on said cylinder and comprising a seat member and a rod secured to and extending downwardly from said seat member, said rod being telescoped within said cylinder for up and down movement therein, spring means in said cylinder engaged with said rod and urging said rod and said seat in an upward direction, bearing means supporting said rod in said cylinder during up and down movement of said rod in said cylinder, and position stabilizing means for said seat connected to and extending between said seat unit and said cylinder to prevent rotation of said seat unit relative to said cylinder wherein said position stabilizing means comprises a flat band member connected to and extending between said seat unit and said cylinder, said band member preventing rotation of said seat unit relative to said cylinder and offering minimal resistance to said up and down movement of said rod in said cylinder, and wherein said bearing means comprises a bearing unit having a sleeve with a plurality of holes formed therein, ball being rotatably mounted in each of said holes, said balls extending from said sleeve, said sleeve encircling said rod so that said balls engage said rod and said cylinder during up and down movement of said rod in said cylinder, and wherein said flat band member is flexed between said connections to provide said minimal resistance to the up and down movement of said rod in said cylinder and wherein said spring means is fixedly secured at its distal ends to said rod and to said cylinder, coacting with said flat band member to yieldably prevent rotation of said seat unit relative to said cylinder.
Claim 3
Dependent Claim
259 words
A shock absorbing seat assembly for use on a vehicle having a tubular seatpost frame such as a bicycle, said assembly comprising an upright cylinder adapted to be secured in said tubular seatpost frame, a seat unit mounted on said cylinder and comprising a seat member and a rod secured to and extending from said seat member, said rod being telescoped in said cylinder for up and down movement therein, spring means in said cylinder and urging said rod in an upward direction, bearing means supporting said rod in said cylinder during up and down movement of said rod in said cylinder, and position stabilizing means for said seat connected to and extending between said seat unit and said vehicle to prevent rotation of said seat unit relative to said vehicle wherein said spring means comprises a spring member having one end engaged with said seatpost frame and the other end engaged with said rod, and wherein said bearing means comprises a bearing unit encircling said rod, and wherein said seat positioning means comprises a flat band member connected to and extendng between said seat unit and said vehicle, said band member being flexed to offer minimal resistance to said up and down movement of said seat unit and further including means for fixedly securing one end of said spring member to seat post and fixedly securing the other end of said spring member to said rod so that said spring member coacts with said flat band member to prevent rotation of said seat unit relative to said vehicle.
Claim 4
