ABSTRACT:
The improved assembly includes a jump seat with a raised back portion and a seat portion hinged thereto and spring raised automatic movement from a horizontal operative position to a raised stored position. The seat back portion holds such spring and is hinged to the vertical arm of an L-shaped wall bracket, which may contain a second spring so that when the seat portion is in the stored position, the seat can be controllably swung into a flat stored position against the wall bracket, which bracket is adapted to be secured to an airplane galley wall or the like. The horizontal portion of the bracket includes a raised post and recess with sloped walls easily releasably seating with and disengaging from the underside of the seat portion. The seat includes a fully adjustable safety belt array, having a pair of parallel vertical shoulder belts releasably separately hooked to a pair of transverse belts. The latter are each adjustable in length. The shoulder belts pass through openings in the seat back and spaced guideways, over a roller and down into a recessed take-up reel which winds them in side-by-side non-overlapping relation for minimal belt bulge. The assembly and array are inexpensive, durable and effective.
