Abstract: A pivoting suspension seat post comprising a tubular post which is adapted to be inserted into a bicycle frame tube for supporting a bicycle seat thereon. A lower body member is secured to the upper end of the post and has the lower ends of front and rear parallel arms pivotally secured thereto. An angular upper body member is pivotally secured to the upper ends of the front and rear parallel arms. A pin is pivotally secured at its upper end to the front parallel arm and has its lower end in engagement with a suspension guide which is slidably received in the upper end of the post. A spring or elastomer members are positioned in the post with the upper end of the spring or the elastomers being received by the suspension guide. A seat mount is provided at the upper end of the upper body member for mounting a bicycle seat thereon. The downward and rearward pivotal movement of the upper body member and the bicycle seat operatively secured thereto is resisted by the spring or elastomer members in the post.

Abstract: A suspension seat post for a bicycle comprising a tubular housing having a cylindrical bore formed therein which has upper and lower bushings positioned therein with the upper and lower bushings having hexagonal bores extending therethrough. A hexagonal slider extends downwardly through the hexagonal bores in the upper and lower bushings. A bolt extends upwardly through the lower end of the lower bushing and is secured to the lower end of the hexagonal slider for movement therewith. As the hexagonal slider moves downwardly, a plurality of elastomeric members, positioned below the lower bushing and the lower end of the lower housing, are compressed.
