Abstract
A snowmobile seat suspension includes a seat support member pivotally connected at its front end to the chassis of a snowmobile, a yieldable support member supporting the rear of the seat support member and at least one air cylinder yieldable in a downward direction but damping in the upward direction. The air cylinder is connected to an inlet hose having a length of 1 to 6 inches, the hose containing a one-way valve which allows air to enter the cylinder without restriction but restricts outflow of air from the cylinder.
