a seat removably mounted with the support frame;
follower means located on one of said support frame and said seat;
guide means located on the other one of said support frame and said seat and adapted for mating engagement with said follower means to support said seat in slidable relationship to said support frame such that said seat is movable between a substantially upright position and a reclining position;
a tray having a relatively flat major surface for supporting articles thereon, said tray having a slot therein;
attachment means for attaching said tray to said support frame such that said tray is moveable between a first position at which said tray is secured when not in use and a second position at which said tray is deployed for use, said seat being moveable relative to said support frame and relative to said tray when said seat is moved between said substantially upright position and said reclining position; and
securing means carried on said seat and being engageable with said slot to secure said tray in said first position, said securing means being disengageable from said slot to release said tray for movement to said second position, said securing means being moveable within said slot when said tray is in said first position and said seat is moved between said substantially upright position and said reclining position, said securing means including a latch assembly having a tubular member projecting from said seat and a swiveable latch member located at one end of said tubular member, said tubular member extending through said slot in said tray when said tray is in said first position, and latch member being adapted to be swiveled to a transverse position with respect to said slot to retain said tray in said first position and being adapted to be swiveled to a longitudinal position relative to said slot to release said tray to be moved from said first position to said second position.

Abstract
An improved adjustable seat having a supporting frame, a seat bucket type removable seat, and a connect-disconnect member disconnectably attaching the removable seat to the frame. The seat bucket and frame are provided with slides which permit relative change in attitude between the seat bucket and the frame in response to manipulation of seat reclining controls by the seat occupant. Included in the base frame are legs which are deformable under high acceleration-deceleration forces to absorb a portion of the energy resulting from the application of such excessive forces.
