Abstract
Abstract A two-passenger seat is supported by a lower cantilever frame which comprises a horizontal seat frame and an inclined truss support frame. The horizontal seat frame includes two elongated horizontal stretcher tubes attached at one end to the wall of a vehicle and at least two cross frame members interconnecting the stretcher tubes at laterally spaced locations. The inclined truss support frame is located beneath the horizontal seat frame; and it includes fore and aft inclined frame members rigidly attached a their upper ends to the stretcher tubes respectively at locations on the aisle side of the transverse center of the horizontal seat frame. The inclined support frame members extend downwardly from the seat frame and they converge toward each other. They are connected to the wall at locations above the floor of the vehicle.

The combination of claim 2 wherein the bolt holes of said end brackets of said stretcher tubes are located respectively forwardly and rearwardly of an associated stretcher tube to prevent twisting of said bracket relative to said wall.
Claim 5
Dependent Claim
44 words
The combination of claim 1 wherein said mounting means comprises an integral elongated bar interconnecting the lower, wall ends of said inclined truss frame members and providing bolt holes adapted to receive bolts for securing said elongated bar to the wall of said vehicle.
Claim 6
Dependent Claim
31 words
The combination of claim 1 wherein said cross frame means includes at least first and second tubular frame members interconnecting said stretcher tubes respectively at the aisle and rear ends thereof.
Claim 7
Dependent Claim
66 words
The system of claim 1 wherein said cross frame means comprises first and second tubular members interconnecting said stretcher tubes, at least one of said cross frame tube members being adjacent the aisle end of said seat, said seat further comprising an upper tubular frame adapted to be secured with bolts to at least one of said stretcher tubes and to said cross frame tubular members.
Claim 8
Dependent Claim
26 words
The system of claim 6 further comprising a single-piece seat shell defining a bucket contour, said cross frame members being depressed to accommodate said bucket shape.
Claim 9
Dependent Claim
59 words
The combination of claim 1 further comprising first and second channel members connected respectively to the wall ends of said horizontal stretcher tubes and extending respectively forwardly and rearwardly of the forward and rear stretcher tubes, each channel member including means providing apertures adapted to receive bolts and securing the respective channel members to a wall of said vehicle.
Claim 10
Dependent Claim
41 words
The combination of claim 1 wherein said cross frame means comprises an integral tube forming a back support for said seat and including forwardly projecting tubular portions interconnected between said horizontal stretcher tubes adjacent respectively the aisle and wall ends thereof.
Claim 11
Dependent Claim
44 words
The combination of claim 1 wherein said cross frame means comprises first and second individual tubular members each formed to provide a back cushion support and including forwardly projecting horizontal portions connected respectively to said rearward and forward stretcher tubes at laterally spaced locations.
Claim 12
Dependent Claim
44 words
The combination of claim 1 wherein said inclined truss frame members are connected to associated stretcher members at locations toward the aisle side of the transverse center thereof to enhance resistance of said seat frame to bending and to twisting about a vertical axis.
