ABSTRACT:
A support for a bicycle type seat provides a pair of brackets depending from the seat structure and clamped to opposite sides of a rigid block having a post receiving hole therethrough for freely receiving a seat supporting post. A sidewall of the post receiving hole is recessed to provide a pair of impact ridges extending parallel to the axis of the hole. Post clamping bolts are provided to screw through the block against a seat supporting post in the hole to force the post against the ridges and embed the same into the post, whereby a post within a wide range of diameters can be positively secured against rotation within the hole. A tubular reinforcement having an axially extending expansion slit may be forced axially into a tubular seat supporting post to prevent a collapse of the latter when forced against the impact ridges. Also preferably the block is provided with bolt receiving holes forwardly and rearwardly of the post receiving hole for passage of bolts that clamp the depending brackets to the block. One of the bolt receiving holes curves about the axis of the bolt within the other bolt receiving hole to enable pivotal adjustment of the brackets and seat about the latter axis.
