ABSTRACT:
A bicycle saddle having an air-filled bladder. The bladder is a durable plastic film chamber having an easily accessible air pump and release valve that allows the bicyclist to adjust the air pressure to his/her comfort without dismounting and or seeking an air supply. The bladder is fitted into a contoured cavity located in a plastic shell base. The bicyclist's weight is supported by the bladder which maintains its shape due to material selection and thickness plus a supporting base. Additional dimensional stability is provided by spot welds of the bladder material to control expansion. Also, an optional skirt is provided on the bladder to further hold it in position when inflated. A simple push pump at the rear and a release valve button under the nose of the saddle enables the saddle to be adjusted for pressure. Metal rails provide generous fore and aft adjustment and a place to firmly clamp the saddle to the bicycle seat post. The saddle is covered with a soft flexible material and adhered to the plastic base. The few number of parts and the absence of mechanical gadgetry, allow the saddle to be manufactured, assembled, and offered at low cost.
