Abstract
Abstract Two tubular cross braces interconnect the arms of a chair frame, to support the load on the seat and to keep the arms from spreading apart. The braces are at opposed upwardly divergent 45* angles to get the upper mounting points of the braces to the frame, further apart to get maximum bearing area. The braces have a middle downward bend to provide clearance for a soft seat and to strengthen the braces. The cross braces support reclining chair linkage hardware. These linkages are provided with sequencing mechanism so arranged that the chair goes from closed upright position to an intermediate TV position before going to a fully reclined position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
129 words
Cross brace means to interconnect sidearms of a chair support, comprising a cross brace having a transverse portion to extend transversely of said chair support, and parallel aligned portions extending from the ends of said transverse portion and adapted to contact inner surfaces of said sidearms, said cross brace comprising a tube, the ends of said parallel portions comprising flattened tube portions closing the ends of said cross brace and having parallel surfaces substantially tangent to the outer sides of said parallel portions, said transverse portion having a central depressed portion extending in a direction opposite to said parallel portions, parts of the transverse portion on opposite sides of said central depressed portion, being formed with pairs of diametrically opposed openings located on axes inclined to said parallel portions.
Claim 2
Dependent Claim
129 words
Cross brace means to interconnect sidearms of a chair support, comprising a cross brace having a transverse portion to extend transversely of said chair support, and parallel aligned portions extending from the ends of said transverse portion and adapted to contact inner surfaces of said sidearms, said cross brace comprising a tube, the ends of said parallel portions comprising flattened tube portions closing the ends of said cross brace and having parallel surfaces substantially tangent to the outer sides of said parallel portions, said transverse portion having a central depressed portion extending in a direction opposite to said parallel portions, parts of the transverse portion on opposite sides of said central depressed portion, being formed with pairs of diametrically opposed openings located on axes inclined to said parallel portions.
Claim 3
Dependent Claim
25 words
The combination of claim 1, said flattened portions being formed with openings to receive fastening means for attaching said cross brace to said side arms.
Claim 4
Dependent Claim
77 words
A chair support comprising sidearms, a pair of spaced cross braces interconnecting said sidearms, each cross brace having a pair of parallel portions and a transverse portion interconnecting said parallel portions, similar symmetrically disposed right and left recliner chair linkages comprising arm-mounting members mounted on the ends of the transverse portions of said cross braces, said linkages being disposed between the parallel portions of said cross braces, and means to attach said parallel portions to said sidearms.
Claim 5
Dependent Claim
77 words
A chair support comprising sidearms, a pair of spaced cross braces interconnecting said sidearms, each cross brace having a pair of parallel portions and a transverse portion interconnecting said parallel portions, similar symmetrically disposed right and left recliner chair linkages comprising arm-mounting members mounted on the ends of the transverse portions of said cross braces, said linkages being disposed between the parallel portions of said cross braces, and means to attach said parallel portions to said sidearms.
Claim 6
Dependent Claim
14 words
The combination of claim 3, said cross braces being located in upwardly divergent angles.
Claim 7
Dependent Claim
13 words
The combination of claim 3, said cross braces being made of metal tubes.
Claim 8
Dependent Claim
27 words
The combination of claim 3, the transverse portion of each cross brace having a central depressed portion extending away from the parallel portions of said cross brace.
Claim 9
Dependent Claim
27 words
The cOmbination of claim 4, the transverse portion of each cross brace having a central depressed portion extending away from the parallel portions of said cross brace.
Claim 10
Dependent Claim
27 words
The combination of claim 7, the ends of said parallel portions being flattened to close said metal tubes, said flattened portions contacting inner surfaces of said sidearms.
Claim 11
Dependent Claim
58 words
The combination of claim 8, said linkages comprising seat-mounting links, seat members attached to said seat-mounting links, a leg-rest means, and link means interconnecting said seat-mounting links, leg-rest means, and arm-mounting members, to permit said seat means to move from closed upright sitting position with the leg-rest means retracted to open reclining position with the leg-rest means projected.
Claim 12
Dependent Claim
16 words
The combination of claim 3, and means to attach said cross braces to said arm-mounting members.
Claim 13
Dependent Claim
57 words
The combination of claim 5, said arm-mounting members having horizontal flanges, said transverse portions of said cross braces having vertically aligned holes, said flanges having holes aligned with said holes in said transverse portions, and means passing through the holes in said transverse portions and in said flanges for attaching said cross braces to said arm-mounting members.
Claim 14
Dependent Claim
27 words
The combination of claim 1, in combination with a chair support having sidearms, and means to attach said sidearms to said parallel, aligned portions of said brace.
Claim 15
Dependent Claim
27 words
The combination of claim 1, a chair seat, means to support said chair seat, and means to mount said chair seat support means on said cross brace.
Claim 16
Dependent Claim
24 words
The combination of claim 13, a chair support having sidearms, and means to attach said sidearms to said parallel aligned portions of said brace.
Claim 17
Dependent Claim
24 words
The combination of claim 14, said chair seat support means comprising recliner chair linkages disposed between said parallel portions and on said transverse portions.
Claim 18
Dependent Claim
81 words
The combination of claim 15, said linkages comprising an extensible and retractable leg-rest means, and said chair seat support means and said leg-rest means being movable from an upright sitting position of the chair rest support means, with the leg-rest means retracted, to a TV reclined position of said chair seat support means with said leg-rest means extended, and from said TV reclined position to a fully reclined position of said chair seat support means with said leg rest means extended.
