Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improved technique for a seat fixing belt used for fixing a foldable seat, such as a rear seat of a one-box automobile, in a folded state.

(Conventional technology) The rear seats installed in one-box automobiles, etc.
It is designed to be foldable in order to make effective use of the luggage compartment.
Accordingly, a seat fixing belt for fixing the seat in the folded state is attached to the seat bag (see Japanese Utility Model Application Publication No. 124543/1983).

Conventional seat fixing belts like this include:
The one shown in FIG. 6 is known.

This conventional seat fixing belt B is attached to a rear seat with a luggage compartment structure, and is attached to the back of a foldable seat back 11 of the rear seat.

This seat fixing belt B has a seat attachment 3 for the seat bag 11 provided at one end of the belt member 2, and a hook member that engages with a receiving metal fitting (not shown) provided on the vehicle body or the seat at the other end of the belt member 2. 4 is provided.

The seat fixture 3 has a belt insertion hole 32. Then, one end of the belt member 2 is passed through this belt insertion hole 32 and folded back at the position of the fitting side folded part 28, and the fitting side folded extension part 21 on the distal end side of this fitting side folded part 28 is connected to the belt intermediate part. The seat mounting tool 3 is attached by sewing the portion 23 with the mounting tool side sewing section 27.

The hook member 4 also has a belt insertion hole 42. Then, the other end of the belt member 2 is inserted into the belt insertion hole 42 and folded back at the hook-side folded portion 29, and the hook-side folded extension portion 24 on the tip side of the hook-side folded portion 29 and the belt intermediate portion 23
The hook member 4 is attached by sewing the two together with the hook-side seam portion 26.

A hook ring 5 for hooking the hook member 4 is inserted into and attached to the folded extension portion 21 on the mounting tool side.

Furthermore, one end and the other end of the rubber band 6 are sewn together with the belt member 2 to both the sewn portions 26 and 27, respectively. The length between the seamed parts 26 and 27 when the rubber band 6 is in its natural length is set to be shorter than the length of the belt member 2 between the seamed parts 26 and 27 by a predetermined amount.

Note that the hook ring 5 is attached to the seventh seat when the seat fixing belt B is attached to the seat bag 11.
As shown in the figure, the seat fixing belt B is folded in two by hooking the hook member 4 on this hook ring 5; If the hook member 4 is attached to the seat back 11 with the hook member 4, it will shake greatly due to vibrations when the vehicle is running, and the hook member 4 will hit the seat back 11, making a banging noise or damaging it, or even interfering with folding or assembling the seat. This is to prevent this from happening.

Furthermore, by attaching the rubber band 6 to the belt member 2, the tension of the rubber band 6 is used to eliminate slack in the belt member 2. If the length of the belt member 2 is fixed to a certain length when the member 4 is engaged with a receiving metal fitting (not shown) provided on the vehicle body, errors in the mounting position of the seat or the receiving metal fitting may occur. If there is variation in the distance between the hook and the receiving metal fitting, if the length of the belt member 2 is short, the hook member 4 may not be able to reach the receiving metal fitting.
On the other hand, if the belt member 2 becomes slack when the hook member 4 is engaged with a receiving metal fitting provided on the vehicle body, and the hook member 4 comes off from the receiving metal fitting, problems such as irritation may occur. If the band 6 is provided and engaged with the receiving metal fitting of the vehicle body by the tension of the rubber band 6, variations in the distance to the receiving metal fitting can be absorbed by the expansion and contraction of the rubber band 6.

In addition, regarding this rubber band 6, the length (effective length) between both the suture parts 26 and 27 in the contracted state
The longer the belt member 2 is, the longer the hanging margin of the belt member 2 can be, and the more the elastic band 6 can expand and contract.

(Problems to be Solved by the Invention) However, in the conventional seat fixing belt B described above, both ends of the rubber band 6 are sewn to the respective seams 26 and 27 of the belt member 2, and in this case, The hook-side seam 26 can be provided at a position close to the hook member 4, but the fixture-side seam 27 is provided with a hook ring for locking the hook member 4 to the fixture-side extension 21. 5 needs to be installed. Therefore, in order to avoid this hooking ring 5, the seat mounting tool 3
It is located far away from the Therefore,
The effective length of the rubber band 6 is shortened by the amount that the hooking ring 5 is attached, which causes the belt member 2
There was a problem in that the elastic band 6 could not be stretched to a large extent due to the short hanging allowance.

(Means for Solving the Problems) The present invention has the following configuration in order to solve the above-mentioned conventional problems.

That is, a seat attachment 3 for attaching to the front seat is attached to one end of the belt member 2 in the form of a belt, while a hook member for hooking to the rear seat or the vehicle body is attached to the other end of the belt member 2. 4 is attached to the seat fixing belt, one end of the belt member 2 is inserted into a belt insertion hole 32 formed in the seat fixture 3, and a folded part on the fixture side located at this insertion part is inserted. Part 2

The other end of the belt member 2 is inserted into the belt insertion hole 42 formed in the hook member 4, and is located in this insertion part. Hook side folded part 2
9, the tip of the hook side folded extension part 24 from this hook side folded part 29 to the other end of the belt member 2, and the other end of the belt intermediate part 23 from the hook side folded part 29 to the center side of the belt member. The other end of the rubber band 6 is sewn to the hook side seam 26 together with the belt member 2, and one end of the rubber band 6 is sewn to the hook side seam 26 in an overlapping state. At a position between the implement side seam part 27 and the fixture side folded part 28, one end of the belt intermediate part 23 and the fixture side folded extension part 21 are sewn by the third seam part 60, and the rubber band 6 is formed such that the length between the hook side seam portion 26 and the third seam portion 60 in the natural length state without applying external force is shorter than the length of the belt intermediate portion 23 between both seam portions 26 and 60. and a hook ring 5 formed in a ring shape so as to be able to engage the hook member 4,
The fitting side folded extension part 21 and the rubber band 6 are inserted between the fitting side stitched part 27 and the third stitched part 60 to be attached.

(Function) In the present invention, the third stitched portion in which the rubber band is sewn is provided between the attachment side stitched portion and the attachment side folded portion, and the rubber band is inserted through the hook ring. The effective length of the band can be made longer, and the rubber band does not cover the hook ring and interfere with its use.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. In the configuration of this embodiment, the same parts as in the configuration of the conventional seat fixing belt B mentioned above are given the same reference numerals in the drawings for convenience.

As shown in FIG. 2, the seat fixing belt A of this embodiment is attached to a seat back 201 of a front seat 200 as a fixing member for folding the rear seat 1 provided in a one-box automobile. To,
Belt member 2, seat fixture 3, hook member 4,
The main components are a hook ring 5 and a rubber band 6.

The seat mounting tool 3 has a mounting hole 31 formed at its distal end for fixing the seat mounting tool 3 to the seat bag 201, and a belt insertion hole 32 formed at its proximal end. It is bent at a slight angle at the intermediate portion between it and the insertion hole 32.

Further, the hook member 4 has a hook portion 41 bent on the distal end side, and a belt insertion hole 42 on the proximal end side.
is formed.

Further, the belt member 2 is formed into a belt shape using a non-stretchable woven fabric. And this belt member 2
A seat fixture 3 and a hook member 4 are attached to both ends of the seat, respectively, and their attachment structures will be described below.

First, to explain the mounting structure of the seat fixture 3, as shown in FIG. folded back,
The attachment side folded extension portion 21 is a portion from this attachment side folded portion 28 to one end of the belt member 2.
and one end of the belt intermediate portion 23, which is the portion from the attachment side folded portion 28 to the belt center side, are overlapped and sewn together at the attachment side stitching portion 27. The belt member 2 inserted into the belt insertion hole 32 in this way
A seat fixture 3 is attached to one end portion of which is formed into a ring shape.

Next, the mounting structure of the hook member 4 will be explained.
Similarly, the other end of the belt member 2 is inserted into the belt insertion hole 42 of the hook member 4, and is folded back at the hook-side folded portion 29, which is the insertion portion. 2
Hook side folded extension part 2 which is the part to the other end
4 and the other end of the belt intermediate portion 23, which is the portion from the hook side folded portion 29 to the belt center side, are overlapped and sewn together at the hook side seam portion 26. The belt member 2 inserted into the belt insertion hole 42 in this way
The other end is formed into a ring shape and a hook member 4 is attached thereto.

Next, the rubber band 6 is formed into a belt shape having approximately the same width as the belt member 2.
The other end is the attachment side seam part 27 of the belt member 2.
The third seat provided at a position closer to the seat fixture 3 than the
At the seam portion 60, the belt is sewn to one end of the belt intermediate portion 23 and the folded extension portion 21 on the attachment side. On the other hand, one end portion of the rubber band 6 is sewn to the belt intermediate portion 23 and the hook side folded extension portion 24 at the hook side seam portion 26 .
Further, the rubber band 6 is formed to be shorter than the length between the third seam portion 60 of the belt intermediate portion 23 and the hook side seam portion 26 in the natural length state where the rubber band 6 is not subjected to any external force. The length of the belt intermediate portion 23 can be extended to the length of the belt intermediate portion 23 between the two belts.

The ring 5 is for hooking the hook member 4 and is formed in a ring shape, between the attachment side seam part 27 and the third seam part 60.
It is provided with the fixture side folded extension part 21 and the rubber band 6 inserted inside.

Note that the seat fixing belt A of this embodiment has a second
As shown in the figure, the seat back 20 of the front seat 200
It has a mounting structure in which the seat mounting tool 3 is fixed in the mounting hole 31 with a screw 310, and the hook member 4 is usually hooked on as shown in Fig. 3. The hook member 4 is folded into a two-fold state hooked on a ring 5, and the hook member 4 may interfere with the outer surface of the seat back 201 due to shaking caused by vibrations when the vehicle is running, causing a knocking sound or scratches. This is to prevent it from getting in the way when folding or assembling.

Further, the rear seat 1 is composed of a seat cushion 10 and a seat bag 11 foldably provided on the seat cushion 10.

The seat cushion 10 is provided with brackets 101 on the left and right sides of the front part, and these brackets 10
1 is rotatably pivoted to the upper end of a stay 71 installed upright on the vehicle body floor 70, and a latch mechanism 102 is attached to the rear left and right sides to removably engage a striker 72 fixed to the vehicle body floor 70, In normal use, the latch mechanism 102 is fixed in a substantially horizontal position engaged with the striker 72, and
With the latch mechanism 102 released from the striker 72, it is folded forward about the pivot portion 103 into an inverted state.

The seat bag 11 is attached to the seat cushion 10 so as to be able to overlap around a pivot portion 113 by operating a device mechanism 111 whose lower left and right sides are provided on the seat cushion 10 side.

In order to fix the rear seat 1 in the folded state using the seat fixing belt A of this embodiment, first, as shown in FIG. 11 into the seat cushion 10 in an overlapping state (in the direction of arrow M), then remove the latch mechanism 102 of the seat cushion 10 from the striker 72, and move the seat cushion 10 forward with the seat bag 11 in a handstand state. (in the direction of arrow N), and then, in this state, attach the hook portion 41 of the hook member 4 provided on the seat fixing belt A pivotally connected to the seat back 201 of the front seat 200 to the seat cushion 10 of the rear seat 1. If it is fixed to the rear surface and engaged with the receiving metal fitting 75 erected toward the seat back 11,
The seat fixing belt A can fix the rear seat 1 in the folded state (solid line state in FIG. 4).

In this case, since the belt member 2 is provided with a sagging allowance due to the tension of the rubber band 6, the rubber band 6 expands and contracts within this sagging allowance, thereby increasing the distance T to the receiving metal fitting 75. Even if there is variation in the value, this can be absorbed by the elastic band 6's expansion and contraction.

Next, the operation of this embodiment will be explained.

When the seat fixing belt A of this embodiment is compared with the conventional seat fixing belt B described above, as shown in FIG. In this case, the hook side seam 26 is also sewn, but on the side of the seat attachment 3 where the hook ring 5 is provided, conventionally, the attachment side stitch is sewn at a position farther from the seat attachment 3 than the hook ring 5. The area 27 was sutured. On the other hand, in this embodiment, the third seam portion 60 is located closer to the seat attachment tool 3 than the hook ring 5.
is sutured to.

Therefore, in the seat fixing belt A of this embodiment, the third stitching portion 6 that stitches the rubber band 6
0 is closer to the seat fixture 3 than the hook ring 5, its effective length _L1 is longer than the conventional effective length _L2 by the length L, and the effective length becomes longer in this way. The hanging allowance of the belt member 2 can be increased accordingly, and as a result, the expansion and contraction dimension of the rubber band 6 is increased, so that it can be adjusted against the variation in the distance T to the receiving metal fitting 75 when fixing the rear seat 1 in the folded state. ,
This variation can be absorbed over a wider range.

Furthermore, since the rubber band 6 is passed through the inside of the hook ring 5, the hook ring 5 is not covered by the rubber band 6, and the hook member 4 is
I have never had a case where the rubber band 6 gets in the way when I hang it on the hook ring 5 as shown in the figure.

Also, attach the seat fixing belt A to the seat bag 20.
Since the seat fixing belt A does not protrude toward the rear seat 1, it does not get in the way when getting on and off from the rear seat 1.

The embodiments of the present invention have been described above with reference to the drawings, but
The specific configuration of the present invention is not limited to this embodiment, and any design changes that do not depart from the gist of the invention are included within the technical scope of the present invention.

In the embodiment, the explanation has been given on the seat attachment side, but it may be similarly attached on the hook member side.

(Effects of the Invention) As explained above, in the seat fixing belt of the present invention, the third seam, which is the seam on the seat attachment side of the rubber band, is connected to the attachment side seam or the hook ring. Since the rubber band is located closer to the seat fixture, the effective length of the rubber band becomes longer, and as a result, the length of the rubber band to be attached can be increased, making it possible to increase the elasticity of the rubber band. .

Further, since there is a margin in the expansion/contraction dimension of the rubber band, the durability of the rubber band can be improved.

Furthermore, since the effective length of the rubber band is increased, it is possible to absorb variations in the distance to the receiving metal fitting over a wide range when the sheet is folded.
