Dependent Claim
64 words
A cantilevered seat for a transit vehicle as recited in claim 6 further comprising a bottom seat bracket having an elongated shape with a pair of spaced mounting bolt apertures therein, said bottom seat bracket being J-shaped with its long dimension mounted in the horizontal portion of the seat shell and its short foot portion mounted in the upright portion of the seat shell.
Claim 9
Dependent Claim
54 words
A cantilevered seat for a transit vehicle as recited in claim 6 further comprising top seat bracket slot means molded into said seat shell along its back surface adjacent each end of said seat shell whereby the top end of said seat can be mounted to a vehicle wall from either of its ends.
Claim 10
Dependent Claim
32 words
A cantilevered seat for a transit vehicle as recited in claim 8 wherein said top seat bracket means comprises a pair of laterally spaced slots for receiving a U-shaped top seat bracket.
Claim 11
Dependent Claim
