Abstract

1338624 Inflatable seats WESTLAND AIRCRAFT Ltd 26 Oct 1972 [25 Nov 1971] 54750/71 Headings A4H and A4M A seat, for fitment in aircraft or other vehicles, includes an inflatable base 14 which defines a plurality of seating sections 11, 12 disposed backto-back about a common backrest 13, the seat including inflation, deflation and pressure relief means. In one embodiment, Figs.1 and 2, the base 14 includes impervious interior diaphragms 17 which optionally include and orifice and inflation 20, deflation 21 and pressure relief 22 valves for the base 14 as a whole or for each compartment thereof. The backrest 13 may be inflated separately from, or simultaneously with the base 14. The base 14 carries flanges 18 for securing to the floor 19 and includes harness attachments 15 and bracing diaphragms therefor. In a modification, Fig.8, the base houses a spring 27 inter-connecting opposed pockets 25 in the base walls, whereby the spring draws the pockets 25 into the base to give a visual indication that the base is under-inflated. In another embodiment, Figs.3 and 4, the base 14 includes lower flanges 18 for securing to the floor and upper flanges 30 for securing to a flexible sheet 32 forming the backrest 13. The upper edge of the sheet 32 is secured by cards 33 to a tube 35 supported from the ceiling by brackets. Air is supplied through the tube 35 and a pipe 38 to a combined inflation/ deflation valve 20. Provision is made for fitting of safety harness. (For Figures see next page)
