Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a webbing cover structure used in a seat belt device for protecting an occupant in a vehicle emergency.

[Background technology]

In a seat belt device, when an occupant wears a webbing, the webbing restrains the occupant in the event of a vehicle emergency to ensure safety.

However, the shoulder webbing, which restrains the occupant's upper body diagonally, often moves relative to the occupant's upper body when the occupant changes his or her driving position during normal vehicle driving, causing wear on the occupant's clothing and wearing ornaments such as brooches. This interferes with the material and causes them to fall off. Furthermore, if the occupant wears a sleeveless jacket with his shoulders exposed, the webbing may come into contact with the occupant's bare skin, causing discomfort.

For this reason, conventional measures have been taken to prevent the webbing from coming into direct contact with the occupant by providing a flexible cover in the middle of the webbing. However, this type of webbing cover is often partially turned over and turned inside out due to the movement of the occupant. Because the tensile force from the take-up device is acting on the webbing,
It is necessary to manually correct any curled parts of the webbing cover each time.

[Purpose of invention]

The present invention has been developed in view of the above circumstances, and its purpose is to provide a webbing cover structure that does not turn over even when an occupant is moving.

[Structure of the idea]

In order to achieve the above object, the invention described in claim (1) of the utility model registration provides at least one of The webbing cover structure includes a flexible webbing cover that can be inserted through and covers the webbing from the vicinity of the slip joint to the vicinity of the tongue plate, the webbing cover covering approximately the entire longitudinal length of the webbing cover along the longitudinal direction of the webbing. It is characterized by having a high-rigidity portion throughout.

In the invention described in utility model registration claim (2), the high rigidity portion is located near both ends of the webbing cover in the width direction and is substantially parallel to both ends of the webbing in the width direction. It is characterized by being constructed by continuous suturing along the .

The invention described in claim (3) of the utility model registration is such that the high-rigidity portion includes a plurality of plate-shaped parts arranged at predetermined intervals along the longitudinal direction of the webbing and on the surface of the webbing cover facing the webbing. It is characterized by being composed of pieces.

Therefore, when the middle part of the webbing passes through the webbing cover due to movement of the occupant, the middle part of the webbing does not turn over.

[Example of idea]

FIG. 1 shows a webbing cover 1 according to this embodiment.
0 is applied, and this seatbelt device uses a webbing 12 to hold the occupant 1 seated on the seat 14 in the event of a vehicle emergency.
6 is set to be in a restrained state.

That is, one type of webbing 12 is anchored to a side wall 20 of the vehicle body via an anchor plate 18, and the middle portion of this webbing 12 passes through a tongue plate 22, a webbing cover 10, and a slip joint 24, and then is transferred to a take-up device 26. It is wound up. This winding device 26 is attached above the anchor plate 18 on the side wall 20 of the vehicle body, and winds up the webbing 12 with a biasing force, and in the event of a vehicle emergency, instantly stops pulling out the webbing 12 to restrain the occupant. It's becoming like that.

The tongue plate 22 has a webbing 12 inserted through an elongated hole 28, and can be engaged with a buckle device 32 erected from a vehicle body floor 30 on the opposite side of the anchor plate 18 via a seat 14. . Further, the slip joint 24 is fixed to the upper part of the vehicle body side wall 20 with an anchor bolt 34, and the middle part of the webbing 12 is folded back through a long hole 36.

Therefore, when the occupant 16 seats the seat 14 and engages the tongue plate 22 with the buckle device 32, the webbing 12 in the take-up device 26 will pass through the slip joint 24 and move toward the tongue plate 22. (in the direction of arrow A) so that the occupant is fastened with a three-point seat belt. When this webbing is attached, the area between the anchor plate 18 and the tongue plate 22 is used as a lap webbing, and the area between the tongue plate 22 and the slip joint 24 is attached to the occupant as a shoulder webbing.

The webbing cover 10 is made of a flexible material and covers the webbing 12 between the slip joint 24 and the tongue plate 22 so that it can be inserted, so even when the occupant 16 moves relative to the seat 14, the webbing 12 itself The clothing and the like of the occupant 16 will not rub against each other and wear out the clothing and the like.

The webbing cover 10 in this embodiment is
As shown in FIGS. 3 and 4, both edges in the width direction are sewn to form a sewn portion 38. This seam portion 38 is provided continuously along the longitudinal direction of the webbing cover 10 and over almost the entire length of the webbing cover 10 in the longitudinal direction, and provides a predetermined rigidity to the webbing cover 10. . Therefore, the attached webbing 12 will not be turned over or turned inside out due to the relative movement of the occupant. However, the flexibility of the webbing cover 10 itself is not impaired.

FIG. 5 shows another embodiment of the present invention.
A plurality of plate-like pieces 39 are fixed to the inner surface of this webbing cover 10. The plate-like pieces 39 have a thin rectangular shape and are attached at predetermined intervals along the longitudinal direction of the webbing cover 10 over substantially the entire length of the webbing cover 10. The webbing cover 10 configured in this manner is given rigidity and becomes difficult to turn over, and the flexibility of the cover itself is maintained. Furthermore, the plate-like piece 39 is attached to the webbing cover 1.
If it is made from a material with a coefficient of friction smaller than 0,
The webbing 12 can be drawn out and rolled in smoothly.

As shown in FIG. 2, holders 40 and 42 are connected to both ends of the webbing cover 10, respectively. The holder 40 is a shaped member that is snap-fitted into the slip joint 24, and is provided with a long hole 44 for inserting the webbing 12. The holder 42 also has a long hole 48 for the webbing 12 so that it can be snapped onto the tongue plate 22.

Adhesive may be used to connect the webbing cover 10 and each holder 40, 42, but both ends of the webbing cover 10 are connected between the holder 40 and the slip joint 24, and between the holder 42 and the tongue plate 2.
It is convenient to make it removable by attaching it between the two.

Webbing cover 10 configured as above
works as follows. When the seat belt device is not in use, the webbing 12 is
Since the webbing cover 10 is wound up to a predetermined length, the webbing cover 10 is contracted into a bellows shape. Next, crew member 16
When the operator pulls out the webbing 12 by holding the tongue plate 22 and engages the buckle device 32, the webbing cover 10 also extends as shown in FIG. Since the webbing cover 10 makes soft contact with the upper body of the occupant 16, it prevents wear of clothing and the like, and does not cause discomfort even when it comes into contact with bare skin.

When attaching the webbing cover 10 to a newly installed seat belt device, the webbing cover 12 is inserted from one end of the webbing 12. Moreover, when attaching to an existing seat belt device, the webbing cover 10 may be formed into a split mold and covered from the outside.

In each of the above embodiments, the webbing cover 10 is attached to the shoulder portion of the webbing 12, but it is also possible to cover the entire length of the webbing 10 if necessary.

[Effect of idea]

As mentioned above, in the present invention, the high rigidity portion is provided along the longitudinal direction of the webbing cover and over almost the entire longitudinal length of the webbing cover, so that the webbing cover is easily moved by the movement of the occupant. It has an excellent effect of preventing the paper from turning over.
