Abstract: There is disclosed a cushion for absorbing energy to dampen vibration, distribute pressure and absorb shock. The cushion has a deformable polyurethane bladder which defines a chamber adapted to contain a fluid, such as air. A piece of viscoelastic material, such as a highly plasticized PVC gel, may be located inside the bladder so that when air is introduced into the chamber, the cushion is capable of absorbing energy to dampen low amplitude vibration, distribute pressure and absorb high amplitude shock. The cushion has a valve in fluid communication with the chamber for selectively varying the amount of air so that the shock absorbing capability of the cushion may be varied.Various embodiments incorporating the cushion are disclosed, including a removable bicycle saddle pad, a bicycle saddle, a wheelchair seat pad and a cyclist's glove.

Abstract: A detachable jacket for a bike seat includes: a jacket having an upper cushioning portion formed with a plurality of cells filled with pressurized fluid in the cells for a comfortable cushioning purpose for a bike driver sitting on the bike seat, and a lower skirt portion connected with the upper cushioning portion and protruding downwardly from the upper cushioning portion for telescopically retaining the jacket on the bike seat, whereby upon releasing of the jacket from the bike seat, the jacket can be repeatedly washed or conveniently maintained.

Abstract: A cycle saddle which accommodates for the movement of a rider's ischial tuberosities. In one embodiment, portions of the saddle substantially coinciding with the rider's ischial tuberosities yield to the downward movement of the ischial tuberosities to reduce the magnitude of the localized pressure concentrations in these areas. In another embodiment, the saddle has a portion which pivots transversely about the central, longitudinal axis of the saddle during the pedalling motion to account not only for the downward movement of an ischial tuberosity, but also for the associated upward movement of the other ischial tuberosity.

Abstract: An adjustable and deformation-resistant cushioning saddle for a bicycle is provided. The saddle includes a saddle frame having an envelope to form a space for receiving a cushioning medium. A fluid bag in the space serves as the cushioning medium and a fluid feeding device communicating with the fluid bag feeds fluid into the bag.

Abstract: A air filled hollow seat has a relatively flexible top portion and a relatively rigid bottom support portion. The bottom support portion is integrally formed to the seat. An air inlet permits the injection of air, under pressure, into the interior of the hollow seat. The interior of the hollow seat has a plurality of partition members essentially separating the hollow interior of the seat into a plurality of individual chambers. The chambers are in air communication with one another.

Abstract: The invention relates to a bicycle, or other two-wheel vehicles, seat which utilizes a concave base to distribute the weight, and corresponding pressure, in a comfortable manner. The base, configured as a section of a hollow spheroid, provides for the distribution of pressure and minimizes the central pressure which would be transmitted to the perineal region of the rider. Further, the seat is cushioned by a spring bracket which serves as the site for attachment to the bicycle. The spring bracket includes a plurality of limbs which slideably bear upon and support the bicycle seat.

Abstract: A weight indicating seat for an exercise device having a pneumatic system associated therewith comprising a pneumatic bladder located in the seat which is connected to a gauge calibrated to indicate weight proportional to the pressure within the bladder. A pumping bulb is also connected to the pneumatic system to allow air to be added to or removed from the bladder.

Abstract: A molded, lightweight pneumatic bicycle saddle. The saddle is molded entirely of plastic and includes a relatively rigid lower wall providing structural support and strength to the saddle and a flexible upper wall providing comfort to the rider. The lower wall may also include a plurality of ridges angularly disposed with respect to one another to provide additional strength thereto. A valve is provided for inflation of the saddle. The bicycle of this invention is molded ina low pressure process such as rotocasting or reaction injection molding. In the rotocasting method, the same material is used for both walls but the upper wall is provided with a lesser thickness than the lower wall. In the reaction injection molding technique, the differences in rigidity are provided by forming each wall of a different material having the desired flexibility.

Abstract: The invention relates to bicycle seats, particularly for racing or long-range touring. Rider comfort and fit to the bicycle is a problem of long standing. A seat assembly (13) provides an elevated region (11c) and a sloping area (11b), contacted by the rider's ischial tuberosities and pubic symphysis respectively, which encourages proper posture and enhances rider comfort. Adjustable tube (52), inserts (55, 56, 61, 67), and sling (46) further fit the rider to the seat and bicycle.
