An adjustable seat assembly for a motorcycle has a seat pan and an adjustment mechanism. The seat pan includes a base portion and two pivoting portions that are pivotally connected to the base portion and are arranged laterally adjacent to one another on the base portion. The base portion has a fastening portion for fastening the seat assembly on the motorcycle. The adjustment mechanism is designed to pivot each of the two pivoting portions in relation to the base portion to adjust a lateral width of the seat assembly. A motorcycle with an adjustable seat assembly is also provided.

A seat for a pedal-powered vehicle is described. The seat includes a support frame, a seat element and a nose. The seat element and the nose are implemented as separated components and are supported by the support frame. The seat element is configured to support at least part of a rider's weight. The seat element carries a pressure-relieving region that is configured to be located at a location corresponding to an ischial tuberosity (IT) of the rider, thereby relieving pressure exerted on the rider's IT's.

A motorcycle seat arrangement with a support structure, a seat cushion, arranged on the support structure, and a seat cushion cover spanning the seat cushion. The support structure has a first side facing the seat cushion and a second side facing away from the seat cushion. The second side of the support structure has an outer region with outer edge sections. Body sections of the seat cushion cover overlaps at least parts of the outer edge sections of the outer region; the seat cushion cover is a three-dimensional, elastic, molded body.

The invention includes apparatus and methods of use for an adjustable disarticulated seat, which in a preferred embodiment may include one, or a plurality of independently or synchronously adjustable disarticulated inserts positioned within insert interface apertures on the distal extended portion of a saddle. An actuator element may be responsive to the one or more disarticulated inserts through one or more cords configured to be retracted or release in response to the action of the actuator causing the extension upward or release downward movement of the one or more inserts within the insert interface aperture.

A bicycle seat cover for a bicycle seat with a rigid substrate and a cushion thereon, includes a stretchable polymeric layer forming a top surface, a seat horn cover, a seat conforming sidewall, and a partial seat bottom surface covering and integral honeycomb cells extending from an underside of the top surface, each cell closed at its top by the top surface and open at its bottom.

A seat that includes an upper surface, a lower surface, one or more pressure sensors communicatively coupled to a controller, and a plurality of artificial muscles disposed between the upper surface and the lower surface. Each of the plurality of artificial muscles is communicatively coupled to the controller. Each of the plurality of artificial muscles includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region.

A retractable cover system may include a cover adapted to cover an object, a holder, and a retraction cord arranged to pull the cover into the holder when the cover is not in use, wherein the cover, the holder and the retraction cord are arranged to cause the cover to collapse as it is pulled into the holder. The cover may include a retraction channel, and the holder may include a storage sleeve. The retraction channel may be arranged to collapse the cover in response to pulling the retraction cord by gathering the cover as the cover is pulled into the storage sleeve by the retraction cord.
