Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a frame structure for a vehicle seat, and particularly to a mounting structure for a slide rail and a vehicle frame.

[Prior Art] Conventionally, as shown in FIG. 2, the attachment part of the slide rail of a vehicle seat has a stay 23 welded to the pipe frame 21 inside the pie frame 21 and above the slide rail 22. It can be installed using bolts and nuts 24 and 25, or as shown in FIGS. 3A and 3B, the pipe frame 31 is crushed at the location corresponding to the attachment part and the pipe frame 31 is attached to the outside of the slide rail 32 using bolts and nuts 34, 25. It was installed by 35. Note that code 2
6 is a zigzag spring, 27 is a retainer for attaching the zigzag spring, 37 is a cover material, and 38 is a spacer.

[Problems to be Solved by the Invention] According to the prior art shown in FIG. 2 above, the tip 24a of the mounting bolt 24 of the slide rail 22 interferes with the zigzag spring 26 when the slide rail 22 is loaded with weight due to seating or the like. I was worried.

In addition, in the case of the prior art shown in FIGS. 3A and 3B, when the lower surface of the frame pipe 31 and the upper part of the upper slide rail 32 are joined, the lower surface of the frame pipe 31 and the upper part of the upper slide rail 32 are connected. Since a space is required for the seat skin to fit in between, use a spacer 38, etc.
It is necessary to form a gap. For this reason, pipe 31
There is a problem in that the spacer 38 must be fixed to the lower surface or the upper surface of the upper slide rail 32 by welding or the like. In addition, in the conventional example shown in FIGS. 3A and 3B, the pipe frame was attached to the outside of the slide rail, so the pipe frame was located on the vehicle body side such as the door, and between it and the vehicle body side, There were layout constraints.

The purpose of this invention is to eliminate the possibility of mounting bolts interfering with zigzag springs, reduce the width of the frame, reduce constraints on the body side such as doors, and eliminate layout constraints. The objective is to provide a mounting structure for

[Means for Solving the Problems] The present invention has been made to solve the above problems, and the mounting structure of the vehicle seat frame of the present invention has the following features in the mounting structure of the vehicle seat frame and the upper slide rail. , a main frame constituting the frame of the seat frame is crushed to form a space on the side of the upper slide rail, and a concave bracket is fixed to the crushed part of the seat frame, and the bracket is attached to the upper slide. It is configured to be fixed to the top of the rail.

[Function] Therefore, the main frame was crushed to form a space on the upper slide rail side, and a concave bracket was fixed to the crushed part of the seat frame, so that the space between the main frame and the bracket was The tip of the mounting bolt can be accommodated. Therefore, the mounting bolt does not come into contact with or interfere with the zigzag spring. Since the bracket is fixed to the top of the upper slide rail, the seat frame is located at the top of the upper slide rail, which allows the width of the frame to be reduced and eliminates layout constraints. can.

[Embodiment] An embodiment of the present invention will be described above based on the drawings. Note that the members, arrangement, etc. described below do not limit the present invention, and can be variously modified within the scope of the spirit of the present invention.

FIG. 1B shows a plan view of the front cushion frame structure, and reference numeral 1 denotes a vehicle seat frame, and the vehicle seat frame 1 of this example is shown in FIG.
is main frame 2, side frame 3,
It is composed of a center plate 4, a trim wire 5, a retainer 6, a zip zag spring 7, and the like. The main frame 2 of this example has a shape in which a pipe-shaped member is bent to match the frame shape of the seat and surrounded by a rectangular shape. A side frame 3 is attached to the lower part of one side (right side in FIG. 1B) of the main frame 2, and a center plate 4 is attached to the other side. As shown in FIG. 1D, the side frame 3 has a cross section L.
It has a letter-like shape, and an engaging portion 3a is formed at the tip. In the front and back portions of the main frame 2 (upper and lower in FIG. 1B), the side frames 3 and the main frame 2 are separated from each other, as shown in FIG. 1C. This front and rear portion is fixed to the upper slide rail 11 and bolt nuts 13 and 14 inside the main frame 2. Note that the reference numeral 12 is a lower slide rail.

A desired number of retainers 6 are disposed at predetermined locations on the left side of the main frame 2 (FIG. 1B).
The engaging portion 3a of the side frame 3 is arranged in alignment with the arrangement position of the retainer 6. The retainer 6 fixes the main frame 2 and the zigzag spring 7, and as shown in FIG. 1D, on the center side (left side in FIG. 1B),
The base of the retainer 6 is attached to the upper surface of the main frame 2 by welding or the like, and the tip of the retainer 6 is formed with a U-shaped engagement part 6a toward the inside of the frame of the main frame 2. The spring 7 is engaged with the spring 7. Also, on the side side (right side in Fig. 1B), the engaging portion 3a at the tip of the side frame 3
and the end of the zigzag spring 7 are engaged.

The main frame 2 on the center side is crushed at two places, front and rear, and the crushed portion of the main frame 2 and the upper end side of the bracket 10, which has a concave cross section, are fixed by welding or the like. As shown in FIG. 1A, a space is formed on the upper slide rail 11 side. There is a mounting hole 1 at the bottom of the bracket 10.
A mounting hole 10a formed at the bottom of the bracket 10 and a mounting hole (not shown) formed at the upper slide rail 11 are aligned, and a mounting hole 10a is formed at the top of the upper slide rail 11. It is fixed using bolt nuts 13 and 14.

[Effects of the invention] As described above, in the present invention, the mounting bolts of the slide rail are located within the seat frame, so there is no interference between the zigzag spring and the mounting bolts. Also, since the width of the seat frame can be made as short as possible, it is possible to create more space between the seat frame and the body. Furthermore, the third A
Unlike the conventional example shown in FIGS. 3 and 3B, a spacer is not required.
