Abstract
An air bag control valve assembly is adapted to control the inflation of a plurality of air bags installed in a seat back rest of an automobile to fit the contour of the seated individual. The valve assembly comprises an integrally assembled body in which a pressure compartment is formed, an inlet for connecting the pressure compartment to a source of air pressure, a plurality of combined check and release valve units for connecting the pressure compartment to each of the air bags, said combined check and release valve units being attached to the interior of said body, and push-button mechanisms attached to said body to correspond to respective ones of said combined check and release valve units, the combined check and release valve units being opened by said push-button mechanisms so that air enclosed within the air bags is expelled backwardly into the pressure compartment and thence discharged into the atmosphere through gaps defined between the body and the push-button mechanisms.
