Abstract

1377311 Cushions UNIVERSAL OIL PRODUCTS CO 28 Feb 1972 9069/72 Heading A4M [Also in Division F2] A cushion 3, Fig. 1 comprises open cell foam material 5 within an airtight envelope 4 fitted with or communicating with a manually operated valve 7 having a push-button 11 operation of which puts the envelope interior in communication with atmosphere, the valve including at least one bleedin orifice 18 and a closure member 15 therefor which operates to close the orifice 18 when the pressure in the envelope 4 is above ambient and opens it when the cushion pressure is below ambient. In one embodiment, Fig. 2, the valve 7 includes a housing 8 for a cylindrical member 12 displaceable by the button 11 to align an annular recess 13 with ports 9, 10. The closure member 15 is biased by a spring 19 to close the orifice 18. When the orifice 18 is open air-flows into the envelope through a recess 17 and a bore 20. In another form, Fig. 4, a push-button displaces a shaft 28 carrying a valve 29 normally closing the open end of the valve body. The valve 29 includes bleed-in orifices 34 and carries a flexible closure washer 33. The washer 33 flexes outwardly to close the orifices 34 when the envelope pressure exceeds ambient and inwardly to permit in-flow of air when the pressure is sub-ambient. In a further form of valve, Fig. 8, the envelope of the cushion 35 is fitted with an annular seat 40 which receives a push-button 42 carrying a flexible diaphragm 41 held over the end of the seat 40 by elastic straps 43 and by super-ambient pressure in the cushion. In this condition notches (44), Fig. 10 (not shown) in the ends of the seat 40 are filled by a soft surface (41<SP>1</SP>) of the diaphragm 41. When the cushion pressure is sub-ambient the notches (44) are opened to allow bleed-in of air.
