Patent ID: 7172180

Claim:
A device for absorbing shocks and vibrations in a bicycle having a seat post, said device comprising: a rearwardly inclined elongated flexible front rod-shaped element of circularly segmental cross section with a rounded surface turned forwardly and a planar surface turned rearwardly, said front rod-shaped element having a lower end received in said post; a rearwardly inclined elongated flexible rear rod-shaped element of circularly segmental cross section with a rounded surface turned rearwardly and a planar surface turned forwardly, said rear rod-shaped element having a lower end received in said post; a front attachment member at an upper end of said front rod-shaped element; a rear attachment member at an upper end of said rear rod-shaped element, said rear rod-shaped element having a greater length between said post and said rear attachment member than the length of said front rod-shaped element between said post and said front attachment member, said front and rear rod-shaped elements being composed of composite material and having the same degree of flex; a bicycle seat pivotally connected to said attachment members so as to remain parallel to itself with back and forth flexing of said rod-shaped elements to absorb shocks and vibration by said flexing; and a plate received in said post between said planar surfaces of said rod-shaped elements and is formed with weight-reducing holes and side notches adapted to be positioned at corresponding notches on at least one of said rod-shaped elements, the notches indicating a degree of flexibility of the device according to a height and weight of a cyclist.
