Abstract
Abstract A multi-passenger seat is supported by a lower cantilever frame which comprises a horizontal seat frame and an inclined arcuate truss support frame. The horizontal seat frame includes two elongated horizontal stretcher members attached at one end to the wall of a vehicle and at least two cross frame members interconnecting the stretcher members at laterally spaced locations. The inclined arcuate truss support frame is located beneath the horizontal seat frame; and it includes fore and aft inclined arcuate frame members rigidly attached at their upper ends to the stretcher tubes respectively at locations preferably on the aisle side of the transverse center of the horizontal seat frame. The inclined arcuate support frame members extend downwardly from the seat frame and preferably they converge toward each other. They are connected to the wall at locations above the floor of the vehicle. Preferably, the attachment means for attaching the seat to the vehicle wall are adjustable to achieve proper horizontal alignment of the seat. A housing surrounds the inclined arcuate support frame members and the area between the inclined members and the horizontal seat frame to house a heater and air conditioner blower and a radioannouncement speaker.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
163 words
In a multi-passenger seat for a vehicle, the combination comprising: a horizontal seat frame having two elongated horizontal stretcher members and cross frame means interconnecting said stretcher members at laterally spaced locations to form a rigid structure; an inclined arcuate truss frame located beneath said horizontal stretcher members and including forward and rear inclined arcuate truss frame members rigidly attached at their upper ends adjacent said stretcher members respectively and inclined downwardly from said attachments the curvature of said truss frame members being upwardly toward said horizontal seat frame thereby providing by said arcuate shape less underseat obstruction from the inclined truss member and a resultant greater leg and foot room; and means for mounting the wall ends of said stretcher members and the lower ends of said inclined arcuate truss frame members to the wall of said vehicle at a location above the floor, said seat being characterized in there being no connection between said seat and the floor of the vehicle.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
14 words
The combination of claim 3 wherein said housing houses a heater-air conditioner blower motor.
Claim 6
Dependent Claim
13 words
The combination of claim 4 wherein said housing further houses an audio speaker.
Claim 7
Dependent Claim
24 words
The combination according to claim 3 wherein the lower portion of said housing conforms to the contour of said inclined arcuate truss frame members.
Claim 8
Dependent Claim
41 words
The seat of claim 1 in which brace members are connected to each of said arcuate truss frame members intermediate the ends thereof; said brace members extending from said truss frame members to said horizontal seat frame and being connected thereto.
Claim 9
Dependent Claim
37 words
The combination according to claim 1 wherein said means for mounting the wall ends of said stretcher members and the lower ends of said inclined arcuate truss frame members to the wall of said vehicle are adjustable.
Claim 10
Dependent Claim
89 words
The combination according to claim 8 wherein each of said adjustable mounting means includes an attachment means comprising a firsT portion adapted to be attached to said wall and having an internally threaded barrel projection extending away from said wall; an externally threaded shoulder bolt threadably received within said internally threaded barrel projection, said shoulder bolt including a stepped-down diameter externally threaded portion being adapted to be received within a mounting hole on the wall side of said seat and rigidly connected through said hole by said nut means.
Claim 11
Dependent Claim
43 words
