Abstract
Abstract A tray for a child's car seat, wherein tension coil springs are used to retain the tray in a position spanning the space between the car seat arm rests. Two laterally spaced leg structures depend from the tray to engage upper surfaces of the arm rests in such fashion as to prevent lateral dislocation of the tray from its installed position. The tray may be quickly removed from the car seat without special tools.

Claim 1
Independent Claim
253 words
In combination with a child' s car seat that comprises a seat section and two laterally-spaced arm rests outboard on either side of said seat section; each arm rest having a transversely curved upper surface that extends downwardly to form a downwardly facing outboard edge (43): the improvement comprising an add-on tray adapted to span the space between the two arm rests at the front end of the seat section, two laterally spaced leg structures depending from the tray for engagement on upper surfaces of the arm rests, and a tension spring means connected to each leg structure, each tension spring means having an upper end thereof anchored to the associated leg structure and a lower end thereof configured as a hook structure for engagement with a downwardly facing outboard edge of the adjacent arm rest; the length of the tension spring means being such that when the leg structures and hook structures are operatively engaged with the arm rests the spring means are stressed so as to hook the tray in a fixed position spanning the two arm rests; each leg structure having a curved undersurface adapted to engage an outboard surface area of the associated arm rest, such that the two leg structures exert an inward clamp force on the arm rests for preventing lateral dislocation of the tray; the outboard edge of each leg structure being located above the outboard edge of the associated arm rest to permit the associated hook structure to operatively engage the arm rest outboard edge.

Claim 3
Dependent Claim
30 words
The improvement of claim 1, and further comprising a resilient elastomeric sheet extending along the curved undersurface of each leg structure for frictional pressure engagement on the associated arm rest.
