A multi-passenger, longitudinal, vehicle seat assembly comprising: a plurality of separate, discrete seats composed of rigid material, arranged in a side-by-side relation and comprising means for seating at least three occupants; each of said rigid seats comprising a substantially horizontally disposed seat portion integral with a substantially vertically disposed back portion having a seat top and a substantially continuous peripheral flange depending downwardly from the periphery of said seat portion and extending rearwardly from the periphery of said back portion; said peripheral flange comprising a flange portion on each side of said seat; a single, unitary supporting and seat frame for all of said seats; said frame comprising a pair of end members each having a substantially horizontally disposed portion terminating at a front end and a substantially vertically disposed portion terminating at a top end; a plurality of spaced-apart intermediate members located between said end members on said frame, each of said intermediate members having a substantially horizontally disposed portion terminating at a front end and a substantially vertically disposed portion terminating at a top end; a horizontally disposed front frame member attached to the front ends of said end members and intermediate members; a horizontally disposed upper frame member attached to the substantially vertically disposed portion of said end members and said intermediate members below the top ends of each and above said substantially horizontally disposed portion of each; a horizontally disposed rear frame member attached to said end members and said intermediate members adjacent the bottom of the substantially vertically disposed portion of each; said horizontally disposed upper frame member being located at about arm-rest height and substantially below said seat tops; there being no horizontally disposed frame member above said upper frame member or between said upper frame member and said rear frame member; means for mounting said unitary frame alongside a wall with said front, rear and upper frame members disposed substantially parallel to said wall; and means for mounting said plurality of rigid seats directly on said unitary frame.
Claim 2
Dependent Claim
335 words
A multi-passenger, longitudinal, vehicle seat assembly comprising: a plurality of separate, discrete seats composed of rigid material, arranged in a side-by-side relation and comprising means for seating at least three occupants; each of said rigid seats comprising a substantially horizontally disposed seat portion integral with a substantially vertically disposed back portion having a seat top and a substantially continuous peripheral flange depending downwardly from the periphery of said seat portion and extending rearwardly from the periphery of said back portion; said peripheral flange comprising a flange portion on each side of said seat; a single, unitary supporting and seat frame for all of said seats; said frame comprising a pair of end members each having a substantially horizontally disposed portion terminating at a front end and a substantially vertically disposed portion terminating at a top end; a plurality of spaced-apart intermediate members located between said end members on said frame, each of said intermediate members having a substantially horizontally disposed portion terminating at a front end and a substantially vertically disposed portion terminating at a top end; a horizontally disposed front frame member attached to the front ends of said end members and intermediate members; a horizontally disposed upper frame member attached to the substantially vertically disposed portion of said end members and said intermediate members below the top ends of each and above said substantially horizontally disposed portion of each; a horizontally disposed rear frame member attached to said end members and said intermediate members adjacent the bottom of the substantially vertically disposed portion of each; said horizontally disposed upper frame member being located at about arm-rest height and substantially below said seat tops; there being no horizontally disposed frame member above said upper frame member or between said upper frame member and said rear frame member; means for mounting said unitary frame alongside a wall with said front, rear and upper frame members disposed substantially parallel to said wall; and means for mounting said plurality of rigid seats directly on said unitary frame.
Claim 3
Dependent Claim
41 words
A seat assembly as recited in claim 1 wherein said plurality of rigid seats comprises: an inner seat; a pair of outer seats; and a pair of sides on said inner seat; each outer seat having an inside and an outside.
Claim 4
Dependent Claim
111 words
A seat assembly as recited in claim 2 wherein said mounting means for the rigid seats comprises: means attaching the peripheral flange portion on one side of said inner seat directly to one intermediate member and means attaching the peripheral flange portion on the other side of said inner seat directly to another intermediate member; means attaching the peripheral flange portion at the inside of one outer seat directly to said peripheral flange portion on said one side of the inner seat; and means attaching the peripheral flange portion at the inside of the other outer seat directly to the peripheral flange portion on said other side of the inner seat.
Claim 5
Dependent Claim
81 words
A seat assembly as recited in claim 3 wherein: said attaching means for the inner seat comprises means attaching the peripheral flange portion on each side of said inner seat to a respective intermediate member at both the horizontally and vertically disposed portion of said member; and said mounting means for the outer seats comprises means attaching the peripheral flange portion on the outside of each outer seat to both the horizontally and vertically disposed portions of a respective end member.
Claim 6
Dependent Claim
66 words
A seat assembly as recited in claim 3 wherein: said means attaching the peripheral flange portion on one side of the inner seat directly to one intermediate member comprises one fastener means; and said means attaching the peripheral flange portion at the inside of one outer seat to said peripheral flange portion on said one side of the inner seat comprises the same one fastener means.
Claim 7
Dependent Claim
50 words
A seat assembly as recited in claim 2 wherein said mounting means for the rigid seats comprises: means on each outer seat adjacent the outside of each for resting on a respective end member; and means adjacent each side of said inner seat for resting on a respective intermediate member;
Claim 8
Dependent Claim
66 words
A seat assembly as recited in claim 2 and comprising: a notch in the peripheral flange portion at the inside of each outer seat, to accommodate said front frame member; and a notch in the peripheral flange portion on each side of said inner seat, to accommodate said front frame member; said inner seat and said outer seats being fixed relative to said front frame member.
Claim 9
Dependent Claim
86 words
A seat assembly as recited in claim 1 wherein: each of said seats has a top located substantially above the top ends of said end and intermediate members; and said assembly comprises means, including that part of a seat's peripheral flange located above the top ends of said end and intermediate members, for imparting to the seat, when mounted on said frame, sufficient structural integrity to withstand normal operating forces on that part of the seat's back portion located above said top ends of said members.
Claim 10
Dependent Claim
78 words
A seat assembly as recited in claim 8 wherein said means for imparting said structural integrity comprises: an extension on the vertically disposed portion of each end member and intermediate member; said extensions being located above said horizontally disposed upper frame member and terminating at said top ends; said extensions providing reinforcement for that part of the seat's back portion located above said upper frame member; said extensions being of sufficient length to contribute to said structural integrity.
Claim 11
Dependent Claim
