Body supported tray table

Claim 1

A body supported tray table comprising a tray table having a table surface and a tray surface, said table surface being substantially flat and said tray surface having a raised rim; body support means comprising longitudinal adjustment means, transverse adjustment means, first and second shoulder hooks, and shoulder hook adjustment means; a joint comprising a cylinder rigidly affixed to said tray table and a coaxial sleeve frictionally coupled to said cylinder and rigidly affixed to said body support means such that said coaxial sleeve is frictionally rotatable relative to said cylinder through at least 270 degrees; said longitudinal adjustment means further comprising an inner coaxial longitudinal cylinder having a proximal end and an outer coaxial longitudinal cylinder having a distal end, said inner coaxial longitudinal cylinder and said outer coaxial cylinder being mutually slidably adjustable and lockably adjustable by means of a spring-loaded detent having a plurality of locking positions, and said proximal end of said inner coaxial longitudinal cylinder being rigidly affixed to said coaxial sleeve; said transverse adjustment means further comprising an outer coaxial transverse cylinder rigidly affixed perpendicular to said distal end of said outer coaxial longitudinal cylinder, first and second inner coaxial transverse cylinders each having an outer end, said first and second inner coaxial transverse cylinders being slidably adjustable within said outer coaxial transverse cylinder, and each of said inner coaxial transverse cylinders being lockably adjustable by means of a spring-loaded detent having a plurality of locking positions; and said shoulder hook adjustment means further comprising first and second ball-and-socket joints located on the respective outer ends of said first and second inner transverse coaxial cylinders and connecting said first and second shoulder hooks to said first and second inner coaxial transverse cylinders respectively.
