Abstract
A bottom cushion for use in a seat of the type used in situations where an occupant could be subjected to spine damaging injury resulting from rapid vertical acceleration or deceleration. The seat cushion includes a frame mounted above the rigid seat pan of the seat with an air-permeable, flexible membrane suspendingly carried in the frame. The seat cushion is provided with a membrane adjusting mechanism by which an occupant applies tension to the membrane to lift his or her posterior above the seat pan for comfort reasons, and has a vertical displacement limiting mechanism which for safety reasons prevents the occupant from lifting the membrane and his or her posterior an excessive distance above the set pan.
