Abstract: A motorcycle seat has a shape forming base on which a selectively deformable cushion is positioned and covered by an exterior covering, the cushion having a foam material encased within an airtight bladder. A valve member located externally of the covering has a conduit which extends through the bladder in sealed fashion and terminates within the foam material. The valve may be selectively opened, and when open while a compression force is applied on the foam, air is expelled from the foam, and if the valve is then closed the foam is formed into the shape of the force applicator. With the valve closed, movement upon the cushion redistributes the air within the foam accordingly. When the compression force is relieved and the valve is opened, the cushion takes on its original shape.

Abstract: A motorcycle seat has a shape forming base on which a selectively deformable cushion is positioned and covered by an exterior covering, the cushion having a foam material encased within an airtight bladder. A valve member located externally of the covering has a conduit which extends through the bladder in sealed fashion and terminates within the foam material. The valve may be selectively opened, and when open while a compressible force is applied on the foam, air is expelled from the foam, and if the valve is then closed the foam is formed into the shape of the force applicator. With the valve closed, movement upon the cushion redistributes the air within the foam accordingly. When the compression force is relieved and the valve is opened, the cushion takes on its original shape. A motorcycle rider sitting on the seat applies the compression force.
