PORTABLE AIR-PRESSURE APPLYING ASSEMBLY FOR SEATS

摘要

An air-pressure applying assembly for a seat, having an occupant holding portion, for selectively applying a desired pressure to the body of a seat occupant. This assembly includes an air-bag assembly, an air-pressure source, an inlet-conduit assembly, an exhaust valve assembly, and a control assembly. The air-bag assembly is removably mountable to the seat occupant holding portion. The inlet-conduit assembly is in fluid communication at one end to the air-pressure source and at another to the air-bag assembly. The exhaust valve assembly is in fluid communication at one end to the inlet conduit assembly and has an air-outlet at the other end. A control assembly is linked to the air pressure source and to the exhaust valve assembly. The control assembly is so configured as to selectively signal the air-pressure source to inflate the air bag assembly so as to apply the desired pressure to the body of the seat occupant and as to selectively signal the exhaust valve assembly to release air from the air-bag assembly.
