Description

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

[Background Art] In a seat belt device, when an occupant wears an occupant restraining webbing, the webbing restrains the occupant in the event of a vehicle emergency, thereby improving the safety of the occupant.

However, when the vehicle is normally running, the occupant's body and webbing often move relative to each other as the occupant changes his or her driving position. For this reason, if a passenger's clothing wears out, if a brooch or other decoration falls off, or if a passenger wearing clothing that exposes bare skin in the shoulder area comes into contact with the passenger's bare skin, the passenger may feel uncomfortable. Causes cheating.

Therefore, 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, the mounting structure of the webbing cover is complicated, and since the mounting structure is simplified by directly fixing the webbing cover to a slip joint, etc., there are problems in that it is difficult to install and remove the webbing cover. Ta.

[Purpose of the invention] Taking the above facts into consideration, the object of the present invention is to obtain a webbing cover mounting structure that is simple in structure and easy to install and remove.

[Structure of the invention] In the webbing cover mounting structure according to the invention,
An end portion of the webbing cover is attached to the first holder, and a webbing supporter is interposed to fit the first holder and the second holder. Also,
The holder to which the webbing cover is attached is provided with an insertion means such as a notch, so that the webbing can be inserted into the webbing insertion hole.

Therefore, it is easy to install and remove the holder,
Therefore, it is possible to easily attach and detach the webbing cover.

[Embodiment of the invention] Fig. 1 shows an embodiment of a seat belt device to which the webbing cover mounting structure according to the invention is applied. webbing 1
2 is used to restrain the occupant 16 seated on the seat 14 in the event of a vehicle emergency.

That is, one end of the webbing 12 is anchored to a side wall 20 of the vehicle body via an anchor plate 18, and after passing through a tongue plate 22 and a slip joint 24, the webbing 12 is wound onto a winding device 26. 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 instantly rolls up the webbing 12 in case of a vehicle emergency.
The passenger is restrained by stopping the drawer of the vehicle.

The tongue plate 22 has a webbing 12 inserted through an elongated hole 28 (FIG. 3), and is engaged with a buckle device 32 that is installed upright from a floor 30 on the opposite side of the anchor plate 18 via a sheet 14. It's becoming possible. In addition, the slip joint 24 is fixed to the upper part of the side wall 20 of the vehicle body with an anchor bolt 34, and the webbing 12 is fixed to the upper part of the side wall 20 of the vehicle body with an elongated hole 36 (Fig. 2).
The middle part is folded back.

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 covers 6, 8, and 10 are located between the take-up device 26 and the slip joint 24, between the slip joint 24 and the tongue plate 22, and between the slip joint 24 and the tongue plate 22, respectively.
It covers the space between the tongue plate 22 and the anchor plate 18. The webbing covers 6 to 10 are cylindrical and made of a flexible material such as wool, silk, or linen, and prevent discomfort from the webbing 12 and abrasion of clothing when the occupant 16 moves relative to the seat 14. I'm starting to do that. however,
The webbing cover 6 is provided to improve the appearance and to prevent dust and the like from being drawn into the winding device 26.

The webbing cover 6, as shown in FIG.
Both longitudinal ends of a rectangular piece of cloth are cut into a square wave shape, and the peaks are folded back and sewn to form a tube 6.
A, 6B are formed, the peaks of one are fitted into the valleys of the other, and the strings 38 pass through the tubes 6A, 6B to cover the webbing 12. The webbings 8 and 10 also have the same structure. Therefore, it is possible to easily attach and detach the webbing cover to and from an existing seat belt device.

A plastic holder for supporting the webbing cover is attached to the end of each webbing cover. As shown in FIG. 2, holders 4 are attached to the slip joint side ends of the webbings 6 and 8, respectively.
0,42 is attached. A claw 40A is formed on the holder 40 and is adapted to engage with a small hole 42A formed in the holder 42. Holders 40, 4 with slip joint 24 interposed
The holders 40 and 42 are designed to cover the outer periphery of the slip joint 24 where the webbing 12 is inserted when the webbing 12 is inserted.
Cutouts 48 and 50 communicating with the outside are formed in the long holes 44 and 46 through which the webbing 12 is inserted.
By passing the webbing 12 through the notches 48, 50 serving as the insertion means, the holders 40, 42 can be easily attached to and removed from the webbing 12. Note that the end surfaces of the cutout portions may be in contact with each other. This is because the elasticity of plastic makes it possible to apply force to separate the two end faces. The slip joint 24 side end of the webbing covers 6 and 8 is
They are bonded to the outer periphery of the elongated holes 44 and 46 of the holders 40 and 42, respectively (the shaded area in FIG. 2). Here, the parts of the webbing covers 6 and 8 through which the strings are inserted are the notches 48 and 50 of the holders 40 and 44, respectively.
It corresponds to. In this state, the joint portions of the webbing covers 6 and 8 through which the strings 38 are inserted face the passenger side, so they are difficult to see when the seat belt is fastened or released, resulting in a good appearance.

Tongue plate 2 of webbing cover 10, 8
As shown in FIG. 3, holders 52 and 54 similar to those described above are attached to the second side end portion, and in this case as well, the joint portion of the webbing cover 10 is made difficult to see.

Here, the anchor plate 18 of the webbing 12
For attachment to the webbing 1, as shown in Figure 4,
The end of the anchor plate 2 is inserted through the long hole 28 of the anchor plate 18, folded back, and sewn to the webbing 12 itself before being inserted. The outer peripheral surfaces of C-shaped holders 58 and 60 are adhered to the inner peripheral surface of the anchor plate 18 side end of the webbing cover 10 (fifth
(see figure). The cutouts 62, 64 of the holders 58, 60 are arranged opposite to each other. The folded portions of the webbing 12 are inserted into the holders 58 and 60, respectively. A cut 66 is formed in the webbing cover 10 near the joint of the holders 58 and 60, so that the holders 58 and 60 can be separated. Attachment and removal of the holders 58 and 60 to and from the webbing 12 are performed using the notches 62 and 6 of the holders 58 and 60.
This can be easily done by passing the folded portions of the webbing 12 through the respective parts of the webbing 12.

A holder 68 similar to the holder 52 is attached to the end of the webbing cover 6 on the take-up device 26 side, and a claw (not shown) of the holder 68 engages with a small hole (not shown) formed in the take-up device 26. It is becoming more and more common.

Next, the operation of the first embodiment configured as described above will be explained.

The webbing covers 6, 8, and 10 can be attached to the seat belt device without removing the existing seat belt device. That is, the webbing is inserted into each elongated hole from the notch of each holder, the holder 68 is fitted to the winding device 26, and the holders 40 and 42 and the holders 54 and 52 are inserted through the slip joint 24 and the tongue plate 22, respectively. to fit. Next, the string 38 is passed through the tubes 6A and 6B, and the webbing cover 6 covers the webbing middle part. The same applies to the other webbing covers 8 and 10. Both ends of the string are fixed to the anchor plate 18, the slip joint 24, the holder or cover end near the elongated hole 28, or the like. In this way, the webbing cover installation work is completed. When cleaning the webbing covers 6, 8, 10, etc., the webbing cover and holder can be removed by performing the operation in reverse to the above. In this way, the attachment of the webbing cover to the seat belt device,
It can be easily removed.

In addition, if the design of the webbing cover is changed as appropriate, it will also contribute to improving the webbing attachment rate, and since the webbing cover can be easily attached and removed, this design change can also be done easily as appropriate.

During webbing attachment and release operations, the webbing 12 slides within the webbing covers 6, 8, and 10. At this time, the webbing cover expands and contracts due to the formation of wrinkles. When the webbing is attached, the webbing covers 8 and 10, which are more flexible than the webbing 12, come into contact with the occupant.
As a result, wear and discomfort on clothes can be prevented.

Next, a second embodiment of the present invention will be described with reference to FIG.

In this embodiment, the fitting structure between the holders attached to the slip joint 24 is different from that in the first embodiment. That is, two sets of keys 74 and key grooves 76 are formed on the joint surfaces of the holders 70 and 72, respectively. The key 74 has a trapezoidal longitudinal cross section, and the tip is longer than the base. On the other hand, the key groove 76 is carved to fit with the key 74.

The holders 70 and 72 are fitted together by sliding their joint surfaces in the longitudinal direction of the key 74 and inserting the key 74 into the keyway 76.

The other points are the same as in the first embodiment. In addition, such a fitting structure is applicable to the tongue plate 2.
It may also be applied to a holder attached to 2.

Next, a third embodiment of the present invention will be described with reference to FIG.

FIG. 8 shows a holder corresponding to FIG. 2, in which the insertion means is not a cutout, but each holder 7.
8 and 80 are each divided into two parts. That is, in order to attach the holders 78 and 80 to the webbing 12, each of the holders divided from the width direction of the webbing 12 is fitted by fitting the claws 82 and 84 into the small holes 86 and 88, and at this time. The webbing 12 is inserted into the long holes 44 and 46 formed. Note that the webbing covers 6 and 8 have cuts (not shown) formed therein, so that the divided pieces of each holder can be separated from each other. However, it is not necessary to form this cut in the divided portion of the webbing cover shown in FIG.

The other points are the same as in the first embodiment.

Note that the webbing cover may be configured to include only the shoulder, that is, only the webbing cover 8.

Furthermore, the webbing cover may be attached to the holder by being clamped onto the holder without being bonded. In this case, it becomes easy to replace only the webbing cover while leaving the holder as is.
