Description

[Technical field]

[0001] The present disclosure relates to a device for preventing a tongue plate from slipping off, the device being provided in a seat belt device of a vehicle such as an automobile. [Background technology]

[0002] 2. Description of the Related Art Vehicles such as automobiles are equipped with seat belt devices for ensuring the safety of occupants. A seat belt device generally includes a webbing belt, which is a belt portion, a tongue plate that is movable in the longitudinal direction of the webbing belt, and a buckle that is fixed to the seat and allows the tongue plate to be attached and detached.

[0003] In a seatbelt device having such a configuration, a tongue stopper (a device for preventing the tongue plate from slipping off) made of plastic resin is provided on the webbing belt for the purpose of preventing the tongue plate from slipping off relative to the webbing belt (for example, Patent Document 1). The tongue stopper generally consists of a first button with a convex portion and a second button with a concave portion, and is fixed by inserting the convex portion into a small hole formed in the webbing and pinching the webbing between the first and second buttons.

[0004] [Patent Document 1] Patent No. 6284501 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the conventional techniques including Patent Document 1, a dedicated device is used to fix the tongue stopper to the webbing belt, which requires manufacturing costs and complicated installation work, resulting in high installation costs. Also, if the tongue stopper comes off the webbing belt for some reason, there is a problem that the repair work requires a certain amount of effort and cost.

[0006] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a tongue plate slippage prevention device that can prevent the tongue plate from slipping off the webbing belt with a simple structure. [Means for solving the problem]

[0007] The tongue plate slippage prevention device disclosed herein is a tongue plate slippage prevention device provided in a seat belt device installed in a vehicle, etc., and has at least one surface which is an adhesive surface, and has a predetermined thickness by being wound around a webbing belt provided in the seat belt device with the adhesive surface in contact with the webbing belt. Effect of the Invention

[0008] According to the tongue plate slippage prevention device of the present disclosure, slippage of the tongue plate relative to the webbing belt can be prevented with a simple configuration. [Brief description of the drawings]

[0009] [Figure 1] 1 is a structural explanatory diagram of a seat belt device including a device for preventing a tongue plate from slipping off according to an embodiment of the present disclosure; [Diagram 2] FIG. 2A is a cross-sectional view of a webbing belt wrapped with a tape member that is a device for preventing the tongue plate from slipping off in one embodiment of the present disclosure; FIG. 2B is a structural explanatory diagram of a tongue plate provided in a seat belt device in one embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A tongue plate slippage prevention device according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a partial view of a seat belt device equipped with a tongue plate slippage prevention device. In Figure 1, a seat belt device 1 installed in a vehicle such as a passenger car (not shown) includes a buckle 2 fixed to a seat (not shown), a tongue plate 3 that can be fixed to the buckle 2, and a webbing belt 4 to which the tongue plate 3 is attached so as to be movable along the longitudinal direction.

[0011] The buckle 2 includes a buckle body 5 having an opening 5a for inserting the tongue plate 3. The buckle 2 includes a built-in locking mechanism (not shown) that functions to reliably fix the tongue plate 3 when the tongue plate 3 is inserted. The tongue plate 3 can be fixed or released by operating a release button 6 attached to the buckle body 5.

[0012] The tongue plate 3 includes a tongue plate body 7 made of a metal such as an aluminum alloy, and a holder 8 that holds one end of the tongue plate body 7. The tongue plate body 7 is a portion that is directly inserted into the buckle 2. The holder 8 has an opening 8a into which the webbing belt 4 is inserted, and the tongue plate 3 is movable along the longitudinal direction of the webbing belt 4 through the opening 8a. The holder 8 is made of, for example, a plastic resin.

[0013] The webbing belt 4 is a strip-shaped woven fabric portion extending in one direction, and refers to a cloth belt generally recognized as a "seat belt."

[0014] A strip-shaped tape member 9 is wound and fixed to the webbing belt 4 at a position below the tongue plate 3. One surface of the tape member 9 is an adhesive surface 9a. As shown in FIG. 2(a), a user (not shown) winds (wraps) the tape member 9 around the webbing belt 4 multiple times with the adhesive surface 9a facing the webbing belt 4. As a result, the tape member 9 having a predetermined thickness is wound around the webbing belt 4 and is adhesively fixed thereto.

[0015] A combined thickness t1 of the webbing belt 4 and the tape member 9 after wrapping is set to be larger than a length dimension t2 (FIG. 2(b)) of the opening 8a of the holder 8. In other words, the tape member 9 can be wrapped around the webbing belt 4 so that the portion of the webbing belt 4 around which the tape member 9 is wrapped has a thickness such that it cannot pass through the opening 8a of the holder 8.

[0016] As a result, even if the tongue plate 3 falls along the longitudinal direction of the webbing belt 4, the holder 8 comes into contact (interferes with) the tape member 9 in the process, thereby preventing the tongue plate 3 from falling further. That is, the tape member 9 functions as a device (tongue stopper) for preventing the tongue plate 3 from slipping off.

[0017] In this way, by using the tape member 9 as a slip prevention device for the tongue plate 3, it is not necessary to fix a button-type tongue stopper consisting of a first button and a second button to the webbing belt 4 using a dedicated device as in the past. In addition, since the user can easily attach it, the manufacturing cost and the attachment cost can be kept low. Furthermore, even if the tape member 9 deteriorates over time, it can be easily replaced. In other words, the effort and cost of repair work can be reduced. In addition, since the tape member is thin and flexible, even if the tape member is sandwiched between the door and the frame of a vehicle, etc., it will not be damaged like a conventional button-type tongue stopper.

[0018] Various materials can be selected as the base material of the tape member 9, which is the portion that supports the adhesive surface 9a (adhesive). For example, plastic films such as polypropylene, polyester, and polyvinyl chloride, paper such as craft paper, and cloth such as cotton and polyester cloth can be used.

[0019] The slippage prevention device for the tongue plate 3 of the present invention is not limited to the embodiment described above, and the design can be appropriately modified within the scope of the invention. For example, the tape member 9 may have adhesive properties on both sides. In such a case, a part that interferes with the holder 8 is provided by adhering some kind of member to the side of the tape member 9 that does not face the webbing belt 4. [Industrial Applicability]

[0020] According to the present invention, it is possible to prevent the tongue plate from slipping off with a simple structure. [Explanation of symbols]
