817,264. Seats. BAYNES AIRCRAFT INTERIORS Ltd., and BAYNES, L. E. Oct. 14, 1957 [Oct. 15, 1956], No. 31352/56. Class 52(2) The back 17a, 24 of an aircraft seat is hinged at 100 to the seat chassis 13, 25 and is normally held in upright position by a latch 23 which, yields under strong impact on the rear of the back to allow it to fold forward. On the chassis is secured a spigot 26 having a shoulder 27 co-operating with a ring of balls 28 surrounded by an annulus 29 of @hard rubber in a housing 30 carried by the seat back. On impact on the seat back, the balls are pressed against the rubber by the spigot, which frees the latch. The arm-rest may be mounted on parallel links on the chassis and held in erected position by a resilient link which may include a releasable catch. The back may be angularly adjustable. The head rest, which is padded on front and rear, may be mounted on a sub-frame carried by the frame of the seat back. The back upholstery squab may be laced to the frame. The head-rest may be narrower than the seat back. Specification 817,263 is referred to. |
