<p>A valve (20) for use with an inflatable cushion (A) having individual inflation zones (r,s,t,u) including a casing (22) with an internal bore (24) and a plurality of openings (26, 28, 30 and 32) along the length of the casing connected to the individual inflation zones by air conduits and a movable slide (34) within the casing bore. The slide has a number of openings (38, 40, 42, and 44) along its length that communicate with an inner bore (36). The valve is opened by aligning the slide openings with the casing openings to allow the inflation zones to communicate through the valve slide bore and is closed by moving the slide openings out of alignment with the casing openings to seal off the inflation zones.</p> |
