';a A FRAME AND A METHOD OF ASSEMBLING THE 5 FRAME FOR A VEHICLE SEAT Field of the Invention The present invention relates to a frame and method of assembling this frame for a seat used in a vehicle such as an automobile and, in particular, to a frame comprising a large number of frame forming members, each formed of a wire or the like, which are superposed on one another in a vertical direction. The superposed portions of the frame forming members are spot welded to one another in the vertical direction to form a sub-assembly, and the welded portions, in the sub-assembly are then spot welded to the vertical wall o 7' 1 1 1- 12 I ~Yc I-U c119--~ 3 o ooo 0 o 0 aOan o 0 00D 0 08 000 surface of a further frame forming member formed of a metal, a board or the like so as to assemble the seat frame.
Description of the Prior Art A conventional seat of this kind is shown in Figs. 1 through 4. In this conventional seat, the forwardly inclinable portions of a rear seat back are allowed to fall forwardly down onto a rear seat cushion so as to bring a trunk room into communication with the inside of a car, which is called a "trunk-through" structure. Therefore, there is formed an opening (11) in a wainscot (10) provided on the rear side of the forwardly inclinable portions (a) of the forwardly inclined rear seat back 15 In such rear seat back a frame is structured as shown in Figs. 3 and 4. As seen in these Figs., in the portion of the frame to be supported by the wainscot (10) of a vehicle body partitioning the above-mentioned car inside and trunk room a 20 great strength is not required. Therefore, a large number of wire rods (23) (27) each having a diameter of the order of a 4 mm are folded into predetermined shapes and are then spot welded to provide a sub-assembly Subsequently, the sub-assembly (2) 25 is spot welded to the two vertical wall surfaces (31) (31) of a frame forming member of a metal plate to which the forwardly inclinable portions are mounted, so that the frame for the rear seat back is produced.
It is noted that the spot welding of the sub-assembly to the vertical wall surfaces of the frame forming member is different in direction from the spot welding of the sub-assembly itself. In particular, when forming the sub-assembly uhe sub-assembly is k~ 'i I a 'i i P I iL ,i ^n ~ci 3Clll Ri3iS: 6r 9

It should be also noted here that, because the wire rods (27) which are to be welded to the frame forming member are so long they cannot be welded to the frame forming member before folding. Thus, after the sub-assembly is formed by folding and spot welding the wire rods (22) the sub-assembly must then be welded to the frame forming member Summary of the Invention The present invention aims at eliminating the drawbacks found in the above-mentioned prior art vehicle seat frame and method of assembling a seat frame in which a large number of wires are folded and welded in the 20 vertical direction to form the sub-assembly and the thus formed sub-assembly is horizontally welded to the vertical walls of another frame forming member.
According to one aspect of the present invention there is provided a method of assembling a frame for vehicle seat which comprises forming a sub-assembly with a plurality of forming members superposed in part on one another in a vertical direction, and welding together the superposed portions of said sub-assembly i-n vortcn.l dairoc n, and welding said sub-assembly to 4he- vertical wall surfaces of a frame forming member, characterized in that an L-shaped mounting member including a horizontal portion and a vertical portion has said vertical portion welded to said vertical wall surfaces of said frame forming member, and the forming members of said sub-assembly having ends Si i 5 which are arranged on said horizontal portion of said mounting member and are welded to said mounting member.
Therefore, since the L-shaped mounting member is previously welded to the vertical wall surfaces of the frame forming member, the sub-assembly can be welded to the mounting member in the same direction as the sub-assembly itself is welded.
BRIEF DESCRIPTION OF THE DRAWINGS Objects and, novel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawings, in which: SFig. 1 is a perspective view of an example of a seat O constructed in accordance with the prior art; Fig. 2 is a section view taken on line II II in Fig. 1; Fig..1 Fig. 3 is a perspective view of a seat frame according to a prior art; r i, *t./1 i 9 o 0 o 4 o ooo 4 444044 0 4 .4 40t 4 444t 00c *s 4 I 4 6 Fig. 4 is a partially enlarged perspective view if the above prior art seat frame; Fig. 5 is a partially enlarged perspective view of an example of a first embodiment of the invention; Fig. 6 is a partially enlarged perspective view of a second embodiment of the invention, illustrating a state before a sub-assembly is welded; and, Fig. 7 is a partially enlarged perspective view of the second embodiment of Fig. 6, illustrating a state after the sub-assembly is welded.
Detailed Description of Preferred Embodiments of the Invention Referring now to Fig. 5, there is shown an example of a first embodiment of the invention. In this 15 figure, reference character designates a mounting member which is spot welded to a vertical wall surface (31) of the frame forming member formed of a metal plate. In the mounting member a wire is folded into a substantially U-shaped form to provide a horizontal 20 portion and the two ends of the horizontal portion (4b) are then folded upwardly and perpendicularly to provide two vertical portions (4a) The vertical portions (4a) (4a) are spot welded to the frame forming member before the sub-assembly comprised of a 25 plurality of wires (21a), (22a), corresponding to the prior art sub-assembly is welded to the horizontal portion (4b).
At each of the longitudinal ends of the frame forming member there is provided a support portion (3a) which is folded at substantially right angles, and the outside surface of the support portion (3a) provides the above-mentioned vertical wall surface (31).
After the frame forming member has the mounting member welded thereto. The sub-assembly (2) is formed of a plurality of wires (21a), (22a), i i 1 7 4 4 44 4 PO *4 4 (27a) which are folded into predetermined shapes and set onto a spot welding jig to weld the wires together.
Simultaneously, when the large number of wires (21a), (22a), (27a) are spot welded to form the sub-assembly, the welded portions of the wires (21a), (22a), forming the sub-assembly are superposed on the horizontal portion (4b) of the mounting member (4) and are spot welded thereto in the same direction as the sub-assembly is spot welded, so that a frame is produced.
In the wires (21a) (22a) (23a) forming a portion of the sub-assembly the portions thereof to be welded to the horizontal portion (4b) of the mounting member are formed of wires having ends which can be properly connectee to the mounting member By use of 15 the mounting member wires having long lengths such as the wire (22) used in the above-mentioned prior art seat frame are not employed.
A structure for mounting the mounting member to the frame forming member as well as other structures of the embodiment are similar to those of the above-mentioned prior art seat frame, except the shapes of the ends of the wires (21a) (22a) (23a) to be welded to the mounting member and, therefore, the description thereof will be omitted here.
In the drawings, reference character (32) designates a rotary hinge provided inside of each of the support portions (3a) (3a) at the ends of the metal plate frame forming member for mounting a forwardly inclinable portion provided in a rear seat back.
This hinge (32) is rotatably connected to the frames of inclinable portions of the rear seat back.
Referring now to Figs. 6 and 7, there is illustrated an example of a second embodiment of the invention employing a mounting member which is formed by folding a metal plate into an L-shaped form and also which is to be welded to the vertical wall surface

8 Specifically, in Fig. 6, there is shown a state of the second embodiment in which the sub-assembly is not yet welded to the mounting member In this state, the sub-assembly is formed of the wires (21a) (22a) (23a) (24a) that are respectively superposed on one another in jig. After this state, the respective wires (21a), (24a) are to be welded together integrally at the same time when the respective ends thereof are welded to the mounting member In Fig. 7, there is shown a state of the second embodiment of the invention, in which the respective o wires (21a), (24a) are integrally welded to one .o another to form the sub-assembly and the thus formed Seas sub-assembly is spot welded to the mounting member o0 15 previously welded to the further frame forming member simultaneously. As can be seen in this figure, the wires are arranged on the mounting member so their end portions extend towards the center of the member but do not touch one another. For this reason, the direction in which the respective wires (21a), (24a) are integrally spot welded to one another is identical with the direction in which the sub-assembly formed of these wires (21a), (24a) is spot welded to the frame forming member via mounting member As has been described hereinbefore, since the L-shaped mounting member having the horizontal and vertical portions has been previously welded to the vertical wall surfaces of the frame forming member It is now possible to superpose on one another the portions of the large number of wires forming the sub-assembly that are to be jointed to the mounting meimber, and to weld these portions in the same direction as the welding of the sub-assembly itself. Therefore, when compared with the prior ait seat frame, the present 14 07t I 9 embodiment is improved greacly in the welding operationability and structure thereof and will provide a seat frame stable in quality.
Further, since the large number of wires forming the sub-assembly are welded to the horizontal portion of the mounting member, the shapes of the wire members forming the sub-assembly can be simplified.
In addition, due to the fact that the sub-assembly can be assembled and welded to the frame forming member simultaneously, it is possible to reduce the time required for welding.
