This seat belt anchor 1 is used for a left seat 5 (passenger seat) and a right seat 6 (driver's seat) of a car.
The mounting structure is such that the mounting base 11 is connected to the mounting hole 11.
It is fixed to the floor panel 73 with bolts 71 and nuts 72 at two locations 0 and 110.

The inner belt 2 has a mounting bracket 21 at its lower end.
The waving 23 is provided with a buckle 22 at the upper end and is formed into a boot type assembly assembled inside a flat boot 24 made of synthetic resin such as vinyl chloride. and is protected using the boot 24 as a cover, and the boot 24 itself is also reinforced with piano wire (not shown) inserted inside.

The lower outer circumferential edge 240 of the boot 24 is formed in a semicircular shape, and the inner surface 241 of the boot is formed with a bulge 242 that allows the folded portion 230 of the waving 23 to escape from the mounting fitting 21. This is because when passing the waving 23 through the belt insertion hole 210 formed in the mounting bracket 21,
Since both side edges of the waving 23 are folded inward, the folded portion 230 bulges due to the folded portions 231, 231, and the folded portion 230 having this bulge is easily stored in the inner surface of the boot 24. and the lower edge 24 of the bulge 242
3 is formed in a straight line along the folded edge.

The inner belts 2, 2 are attached to the vertical wall portion 4 of the console box 4 provided on the vehicle body floor 7.
Gap 74, 7 between 1, 41 and both sheets 5, 6
4, and its lower end extends upward through the seatbelt anchor 1 at the belt attachment portion 12,
12, and the mounting structure in this case is that a different diameter hole 120 as a belt mounting hole has an arcuate part and a straight part, and a circular part and a straight part correspond to the different diameter hole 120. A different diameter pin 45 having a partially flat surface is inserted into the belt attachment part 12 in a state protruding from the outside, and the different diameter pin 45 has a flat surface.
, a collar 3 made of hard and smooth synthetic resin such as polyacetal or nylon, a mounting bracket 21 for the waving 23, a wave spring washer 29, and a stopper 2.
7 are fitted in order. The collar 3 and the mounting bracket 21 have circular holes 31 and 211, respectively, and an insertion collar 28 having a circular hole and a stepped circular outer circumference is inserted into the circular holes 31 and 211. It is rotatably fitted to the different diameter pin 45 via the insertion collar 28. The stopper 27 is fixed to the different diameter pin 45 through a different diameter hole 270 formed to match the outer shape of the different diameter pin 45, and a locking piece 271 protruding toward the belt attachment portion 12 is attached to the attachment piece 271. It has a structure in which it is inserted into a locking groove 212 formed on the outer periphery of the metal fitting 21. In addition, insert collar 2
8 has its inner surface 281 abutted against the outer surface 122 of the belt attachment portion 12, and the wave spring washer 29 is interposed between the attachment fitting 21 and the stopper 27 to press the attachment fitting 21 toward the belt attachment portion 12. This gives a sense of moderation when rotating the inner belt.

Therefore, in this attachment structure, the different diameter pin 45 is fixed to the belt attachment part 12 via the different diameter hole 120 as a belt attachment hole, and the different diameter pin 45
Since the stopper 27 is fixed through the hole 270 of different diameter, the inner belt 2 can rotate within the range in which both ends of the locking groove 212 formed in the mounting bracket 21 are locked by the locking pieces 271 of the stopper 27. It's becoming possible.

Next, the collar 3 is interposed between the outer surface 122 of the belt attachment portion of the seat belt anchor 1 and the inner surface 241 of the boot of the inner belt 2.
An assembly space 42 for the console box 4 is secured between the inner surface 241 of the boot and the inner surface 241 of the boot.

Further, the collar 3 is formed with a flange 32 that faces the inner surface 241 of the boot.
The lower outer peripheral edge 320 is the lower outer peripheral edge 2 of the boot 24.
40 in a semi-circular shape, and the upper edge 3
21 is a bulge 24 formed on the inner surface 241 of the boot.
The collar 3 and the boot 24 are rotated together by the upper edge 321 and the lower edge 243 of the bulge 242. It is locked in the rotational direction so that the

In the figure, 51 and 61 are device covers for seat reclining, respectively, and seat cushions 52 and 62 of the left and right seats 5 and 6, respectively.
and the seat backs 53, 63. Further, 54 and 64 are sheet sliders.

Next, the operation of this embodiment will be explained.

The console box 4 is installed by inserting the vertical wall portion 41 between the outer surface 122 of the belt attachment portion of the seat belt anchor 1 and the inner surface 241 of the boot of the inner belt 2, and the collar 3 is interposed between this. Therefore, the collar 3 makes it possible to secure a space 42 for assembling the console box 4 with a constant width between the outer surface 122 of the belt attachment part and the inner surface 241 of the boot.
Since the collar 3 supports the inner surface 241 of the boot, the standing state of the inner belt 2 is stabilized.

Further, this collar 3 is formed with a flange 32 that faces the inner surface 241 of the boot, and the lower outer peripheral edge 320 of this flange 32 is formed in a shape that follows the lower outer peripheral edge 240 of the boot 24. Therefore, both lower outer circumferential edges 320, 240 are aligned, and a good-looking mating state is obtained.Since both lower outer circumferential edges 320, 240 are aligned, the entire area of the lower end of the boot inner surface 241 is The inner belt 2 is supported by the flange 32, and the inner belt 2 has a wider support area.
In order to further stabilize the upright state of the boot and to prevent the lower outer circumferential edge 240 of the boot inner surface 241 from falling toward the vertical wall 41 of the console box 4, the lower outer peripheral edge 240 of the boot inner surface 241 is This prevents the side outer circumferential edges 240 from coming into contact with each other, and when the inner belt 2 rotates, no crackling noise is generated from this part, and it is possible to prevent the two from coming together and breaking.

Further, the upper edge 321 of the flange 32 extends parallel to and in contact with the bulge 242 formed on the boot 24, and is locked in the rotational direction so that the collar 3 and the boot 24 rotate together. Therefore, when the inner belt 2 rotates, the collar 3 also rotates, and the flange 32 and the boot 24 rotate at any rotational position of the inner belt 2.
This means that the lower outer circumferential edges 320 and 240 are positioned at the original meeting position where they are aligned, and there has never been a case where slippage occurs in the meeting state and misalignment occurs, and between the flange 32 and the boot 24. , no rattling noise is generated when the inner belt 2 rotates.

In this embodiment, since the installation guide portions 121, 121 of the console box 4 are formed at the upper ends of the belt attachment portions 12, 12 of the seat belt anchor 1, the installation guide portions 121, 1
The console box 4 can be assembled to the vehicle body floor 7 while being guided along the line 21, making the installation work of the console box 4 easy.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to these embodiments, and the present invention may be modified without departing from the gist of the invention. included in the technical scope of

For example, in the embodiment, the seat belt anchors have a left and right integrated structure with left and right belt attachment parts formed on both sides of the mounting base, but the left and right inner belts are attached to separate left and right seat belt anchors, respectively. However, as in the example, a seat belt anchor with an integral structure on the left and right sides is used, and this seat belt anchor is installed twice on the vehicle floor.
If the seat belt anchor is fixed at a certain point, the installation position of the seat belt anchor can be accurately determined, and there is an advantage that it can be firmly fixed at that position.

(Effects of the Invention) As explained above, in the present invention, the assembly of the console box is achieved by the collar interposed between the outer surface of the belt attachment part of the seat belt anchor and the inner surface of the boot of the inner belt. A space can be secured with a constant width, and the inner belt can be held in a stable upright state by the collar.

Further, the flange formed on the collar allows a large area for supporting the inner belt, so that the standing state of the inner belt is more stable, and the flange can be provided in an attractive manner.

Furthermore, since the collar follows the rotation of the inner belt, the flange can be positioned at a predetermined position no matter what rotational position the inner belt is in.

This effect prevents interference with the console box and seat due to the tilting (rotation) of the inner belt, and prevents damage to various parts and generation of friction noise due to this interference. Both lower outer circumferential edges are aligned with each other, which improves the appearance, and also prevents slippage between the flange and the boot, thereby preventing abrasion and friction noise between the two.
