Abstract
Abstract A chair structure is supported upon a plurality of spaced support frames, each having a rear vertical leg, and a front leg extending from said rear leg forwardly and then upwardly and forwardly to a spaced distance from the top of the rear leg, the frame having horizontal rails connecting the front and rear legs and extending rearwardly therefrom, attachment means being provided for securing the rearwardly extending rails to a wall or other support. Longitudinal rails connect the spaced support frames, and chairs are mounted upon the support frame structure. Closure panels extend at an inclination from the bottom of the rear leg upwardly to enclose the front of the seat structure, while side panels close the ends of the seat structure. At the top of the seat structure, a plastic closure is provided for adjustably closing the space between the top of the seat structure and the wall.

Claim 1
Independent Claim
101 words
In a cantilever seat structure adapted to be supported upon a floor and adjacent wall, a plurality of spaced support frames parallel with said wall, each frame having a base for resting on said floor, a rear leg extending upwardly from said base, a front leg extending from the front of said base forwardly and upwardly to a spaced distance from the top of said vertical leg, said frame also including horizontal rails connecting said front and rear legs and extending rearwardly therefrom for connection to said wall, longitudinal rails connecting said support frames, and chairs mounted upon said support frames.
Claim 2
Dependent Claim
101 words
In a cantilever seat structure adapted to be supported upon a floor and adjacent wall, a plurality of spaced support frames parallel with said wall, each frame having a base for resting on said floor, a rear leg extending upwardly from said base, a front leg extending from the front of said base forwardly and upwardly to a spaced distance from the top of said vertical leg, said frame also including horizontal rails connecting said front and rear legs and extending rearwardly therefrom for connection to said wall, longitudinal rails connecting said support frames, and chairs mounted upon said support frames.
Claim 3
Dependent Claim
