DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning pad for a webbing guide, and more particularly to a cleaning pad for a webbing guide that can recover and maintain the retractability of a retractor.

[0002]

2. Description of the Related Art In general, a three-point seat belt device using continuous webbing is used as a seat belt device for restraining the body of an occupant sitting on a seat of an automobile or an aircraft by webbing.

In this type of seat belt device, one end of a webbing 21 is engaged with a retractor (winding device) 23 attached to the lower end of a center pillar 22, as in an automobile seat belt device shown in FIG. The other end is fixed to an anchor plate 25 which is supported at the lower part of the vehicle body through a through anchor 24 attached to the upper end of the center pillar 22. And the anchor plate 25
An occupant is restrained by a seat 28 by engaging a slut tongue 26 provided at an intermediate portion of the webbing between the vehicle and the through anchor 24 with a buckle 27 erected at the center of the vehicle body.

[0004] In view of the body mounting relationship of the vehicle such as the retractor 23, the three-point seat belt device includes not only the through anchor 24 and the sluting 26 but also a belt guide or through belt (not shown) or a retractor outlet. Webbing 21 like a webbing guide
Many webbing guides for changing the direction of the webbing 21 for guiding the webbing to a predetermined position are provided.

[0005] Such a webbing guide is provided with a long hole for guiding the webbing 21, and the webbing 21 inserted into the long hole slides in direct contact. Therefore, in order to improve the winding characteristics when the webbing is wound and the operational feeling when the webbing is pulled out, it is necessary to suppress the frictional resistance between the webbing guide and the webbing as low as possible.

In view of this, the surface shape of at least the portion of the webbing guide that contacts the webbing is smoothed by resin coating. Further, the webbing is subjected to a surface treatment with a surface oil agent after weaving to improve slipperiness and abrasion resistance.

[0007]

However, in the above-described seat belt device, when used for a long period of time, dirt adheres to the surface of the webbing, and the surface oil is also consumed. The webbing guide is mixed with surface oil of the webbing, dirt of hands, lint, dust in the air, and the like, and gradually accumulates on the sliding surface of the webbing guide, and the amount thereof gradually increases. This stain is generally called gum, and this gum gradually accumulates (hereinafter, gum accumulation is referred to as gum up). As described above, when used for a long period of time, the frictional resistance between the webbing guide and the webbing increases due to gum up, and the retractability of the retractor decreases.

Conventionally, the only means for cleaning this type of webbing guide or the like is a cloth containing a solvent such as a cleaning agent, and there is no suitable cleaning means. It was necessary, and cleaning work was not easy for ordinary drivers. Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to remove gum up of a webbing guide after long-term use and reduce frictional resistance between the webbing guide and the webbing. Another object of the present invention is to provide a cleaning pad for a webbing guide that can recover and maintain the winding property of a retractor.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of implanting a large number of short and highly rigid monofilaments on the surface of a base fabric, and impregnating the base fabric with a liquid for preventing contamination. This is achieved by a cleaning pad for the webbing guide.

It is desirable to laminate a synthetic resin film on the back surface of the base cloth. The thickness of the monofilament is preferably 0.3 to 0.6 mm in diameter, the length protruding from the base fabric is preferably 1 to 2 mm, and the rigidity is 5000 to 3 in elastic modulus.
0000 kg / cm ² is preferred. The material of the monofilament is preferably a polyamide monofilament, but may be a monofilament such as polyethylene terephthalate or polypropylene. Base cloth thickness is 1-2m
m is preferred. The thickness of the webbing guide cleaning pad is preferably 3 mm or less, and the length is preferably 15 to 25 cm, and particularly preferably about 20 cm. As the contamination preventing liquid, a fluororesin paint is preferable.

According to the above configuration, the cleaning pad for the webbing guide is passed through the elongated hole of the webbing guide, and the surface from which the monofilament is projected is brought into contact with the sliding surface of the webbing guide, so that the gum-up is performed by the monofilament. Can be scraped off.
Further, by applying a new anti-contamination liquid impregnated in the base cloth to the cleaned sliding surface of the webbing guide to form a film, it is possible to prevent dirt from adhering after cleaning.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of an embodiment of the present invention, and FIG. 2 is a perspective view of a state in which the embodiment is housed in a packaging bag.

[0013] The cleaning pad 5 for the webbing guide comprises the base cloth 1.
Has a two-layer structure in which a synthetic resin film 2 is laminated on the back surface of the substrate. Then, a U-shaped monofilament 4 is embedded and implanted in the base fabric 1 with both ends protruding short. As the monofilament 4, a webbing guide that does not damage the webbing guide, protrudes in a short length to the extent that the gum up is scraped off, and has a suitable rigidity is used. As the structure up to this point, for example, a base cloth of a commercially available velvet type surface fastener (for example, a product name of Kuraray Co., Ltd., magic tape HL2-WB) can be used. Further, the back surface of the base cloth 1 and the base cloth 1 are impregnated with the pollution preventing liquid 3. As the pollution preventing liquid 3, for example, Nippon Paint Co., Ltd. product name, Duflon K300 is preferable.

The webbing guide cleaning pad 5 of the present embodiment thus constructed is passed through the oblong hole of the webbing guide so that the surface from which the monofilament 4 protrudes is brought into contact with the sliding surface, so that the movement of the webbing is the same as that of the webbing. By rubbing, dirt, lint, dust in the air, and the like are mixed, and the monofilament 4 scrapes the gum-up gradually deposited on the sliding surface of the webbing guide.

Further, by this rubbing and scraping operation, the pollution preventing liquid 3 oozes out from the base cloth 1, adheres to the surface of the webbing guide, is applied to the sliding surface of the webbing guide, and is applied to the sliding surface of the webbing guide. Since a fluororesin-based film is formed on the surface of the webbing, dirt which is a component of gum-up such as a surface oil agent of the webbing and hand oil is less likely to adhere to the sliding surface of the webbing guide, and the clean state is maintained.

As described above, the sliding surface of the webbing guide polished by the webbing guide cleaning pad 5 is surely removed from gumming up, and a coating of the contamination preventing liquid 3 is formed on the sliding surface. Therefore, it is difficult for dirt to adhere. Therefore, the frictional resistance between the webbing guide and the webbing is reduced, and the retractability of the retractor is satisfactorily recovered, and that state is maintained. That is, by removing the gum-up on the sliding surface of the webbing guide by the webbing guide cleaning pad 5, the winding property of the retractor can be easily recovered by a simple operation.

FIG. 2 shows a state in which the webbing guide cleaning pad 5 is housed in a packaging bag 6, and the opening of the packaging bag 6 houses the webbing guide cleaning pad 5. Later, sealing is performed by the heat seal 7. In addition, by providing a sealing means that can be opened and closed at this opening, the sealed state is maintained even after opening, and the cleaning state of the webbing guide cleaning pad 5 is maintained a plurality of times, and the good use state is maintained. It is assumed that.

Incidentally, the cleaning pad 5 for webbing guide of the present invention is not limited to the above-described embodiment, and it goes without saying that the cleaning pad 5 may have various configurations. If necessary, the base cloth 1
The structure which does not laminate | stack the synthetic resin film 2 on the back surface of may be sufficient. The contamination-preventing liquid 3 is also an appropriate contamination-preventing liquid, for example, silicone oil as a so-called release agent for preventing a molded article from adhering to a mold during resin molding, or Because the painted surface becomes hydrophilic,
Hydrophilic paint effective for preventing adhesion of oil-based dirt, such as Duflon K500 S (trade name, manufactured by Nippon Paint Co., Ltd.)
The C-clear or the static elimination paint may be used, and the substrate 1 may be made of another appropriate cloth material. Furthermore, the monofilament 4 may use fibers of other shapes and materials.

[0019]

As described above, according to the present invention, a large number of short and high-rigidity monofilaments are implanted on the surface of the base fabric, and the base fabric is impregnated with a pollution preventing liquid. The surface of the webbing is reliably scraped off the gum-up consisting of oils and hand oils, and the webbing guide is cleaned with a cleaning pad for the webbing guide. On the sliding surface of the webbing guide, a film of a liquid for preventing contamination is formed. Therefore, it is difficult for dirt to adhere.

Accordingly, the frictional resistance between the webbing guide and the webbing is reduced, and the retractability of the retractor is extremely restored, and the state is maintained. That is, by removing the gum-up on the sliding surface of the webbing guide by the cleaning pad for the webbing guide, the winding property of the retractor can be easily recovered by a simple operation.
