Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a seatbelt anchor device capable of supporting an intermediate portion of webbing in a position-adjustable manner.

《Prior art and its problems》 In general, seat belt devices use occupant restraint webbing to restrain the occupant so that the occupant does not collide with dangerous objects in the event of a vehicle emergency. The force creates a large tension. Therefore, it is necessary to reliably support this tension to the vehicle body using an anchor device.

Incidentally, the physiques of occupants vary widely, and it is desirable to change the position of the support part of the webbing depending on the physique of the occupant. Many models are designed to allow adjustment of the vertical position of the pointer (pointing).

4 to 7 show conventional examples of such anchor devices.

In the figure, an intermediate portion 1 a of the webbing 1 is attached to a boss portion 7 of an anchor plate 4 by an anchor bolt 3 passing through a support portion 2 .

The anchor plate 4 is configured to be able to move vertically with respect to the vehicle body, and the supporting portion 2 also moves vertically accordingly, so that the center pillar garnish 8 attached to the center pillar P of the vehicle body An adjustment slot 9 is provided in the.

In addition, for the purpose of shielding the adjustment slot 9, a flat slide plate 1 is provided on the upper surface of the anchor plate 4 and moves together with the anchor plate 4.
0 is provided, and is arranged on the back side of the center pillar garnish 8 so as to cover the adjustment slot 9 no matter where the support part 2 is located in the adjustment slot 9 of the center pillar garnish 8. .

When changing the support position of the support part 2, the lock release knob 6 is operated to make the anchor plate 4 movable relative to the vehicle body panel, and the lock release knob 6 is also operated to release the lock release knob 6. The anchor plate 4 is fixed at the proper position by performing the operation in the opposite direction.

By the way, in this type of anchor device, the center pillar garnish 8 is generally formed of synthetic resin, and therefore the periphery of the adjustment slot 9 opened in the center pillar garnish 8 is shaped like a flat plate. If the cutting process was performed as-is, there was a problem in that the peripheral edge portion of the adjustment slot 9 had poor rigidity and was easily deformed by external force.

For this reason, the upper and lower peripheral edges 9A of the normal adjustment slot 9,
9A and the left and right peripheral edges 9B, 9B are provided with flange portions 9a, 9 that protrude from the back surface of the center pillar garnish 8, as shown in FIGS.
a, 9b, 9b are formed, and the peripheral edge 9 of the adjustment slot 9
The structure was such that parts A to 9B were made rigid.

Therefore, the slide plate 10 is configured to be sandwiched between the flanges 9a to 9b and a guide plate 11 that is disposed on the lower surface of the slide plate 10 and holds the slide plate 10.

Further, guide pieces 10c, 10c are bent on both sides of the slide plate 10, and the guide pieces 10c, 10c are guided by the left and right flange parts 9b, 9b to move up and down. It is configured to sandwich the side surface of 9b.

Therefore, when adjusting the position of the support part 2, if the anchor plate 4 is slid in the vertical direction,
In the slide plate 10, the guide pieces 10c, 10c on both sides of the slide plate 10 slide using the left and right flange parts 9b, 9b of the adjustment slot 9 as guides, and each flange part 9a to 9b
will slide while in contact with the upper surface of the slide plate 10.

Therefore, on the left and right sides of the top surface of the slide plate 10, the left and right flanges 9b, 9b provide
The width of the flange portions 9b and the lower surface of the 9b is approximately the same, and the scratches are made in the vertical direction along the lower surface of the flange portions 9b and 9b.

Further, the upper and lower sides of the upper surface of the slide plate 10 are scratched by the upper and lower flange portions 9a, 9a, with the width of the lateral direction of the flange portions 9a, 9a, and the vertical movement length of the slide plate 10. It happens.

Therefore, when the slide plate 10 is displaced laterally, the scratches formed by the left and right flanges 9b, 9b are formed on the left and right peripheral edges 9a, 9b of the adjustment slot 9.
The upper and lower flange portions 9B and 9B are exposed by sliding the slide plate 10.
The scratches formed by the grooves 9a and 9a are exposed from the upper and lower peripheral edges 9A and 9A within the adjustment slot 9.

In the slide plate 10, the guide pieces 10c, 10c formed on both sides of the slide plate 10, as described above, are connected to the upper and lower flange parts 9.
Since it is configured to move up and down while being guided by b and 9b, the width of the deviation due to lateral deviation is small. , 9a will appear alternately and completely within the adjustment slot 9 from the upper and lower peripheral edges 9A, 9A as the slide plate 10 slides.

As described above, in the conventional seat belt anchor device, it is not possible to provide rigidity to the peripheral edges 9A to 9B of the adjustment slot 9 formed in the center pillar garnish 8 by using the respective flanges 9a to 9b. Although it is possible, each flange part 9a to 9b
Since the tip side of the slide plate 10 is in contact with the top surface of the slide plate 10, there is a drawback that the top surface of the slide plate 10 is scratched when sliding.Moreover, in this case, in particular, the scratches rubbed by the upper and lower flanges 9a, 9a are As the plate 10 slides, the upper and lower peripheral edges 9A, 9A are alternately exposed entirely within the adjustment slot 9, resulting in a problem in that the appearance is extremely poor.

《Purpose of the invention》 This invention was devised in view of the above circumstances, and its purpose is to adjust the upper surface of the slide plate by the flange of the adjustment slot formed in the center pillar garnish. To provide a seat belt anchor device that prevents the seat belt from being damaged and has a good appearance.
