Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a buckle stalk that supports the buckle of a seat belt of an automobile or the like against the vehicle body. The buckle stalk main body 1 of the seat belt is generally installed on the side of the seat 2 as shown in FIG. A device that supports the buckle body 5 of the seat belt 4, holds the buckle body 5 in a position suitable for attaching and detaching the seat belt 4, and allows the operation of attaching and releasing the seat belt to be performed with one hand. It is.

This type of buckle stalk has the rigidity to stand on its own at all times and hold the buckle body in a predetermined position on the side of the seat, and when worn, it follows the movement of the wearer's body and moves to the seat. It is necessary to have appropriate flexibility so that the belt can be fitted. Furthermore, when a large load is applied to the seat belt due to an accident or the like, it must have enough strength to reliably support the load.

Conventional technology This type of buckle stalk was developed in the 1980s.
The one described in Publication No.-106861 is known. In this item, a stalk body is constructed by covering webbing with loops formed at both ends with a covering member, an anchor member is attached to the lower end of the stalk body, and a buckle body is attached to the upper end of the stalk body. An extension piece is formed on the base plate of the frame of the buckle body, and the stalk body is held between the extension piece and the cover.

The covering member has a bellows shape with a plurality of projections and recesses, and the upper end of the covering member is formed with a narrow part without the projections and recesses, and the extension part and the cover are connected to the narrow part and the inside thereof. A structure is shown in which the inserted webbing is sandwiched, and the webbing is reinforced with a reinforcing core member over its entire length.

Thus, the buckle stalk is made to stand up by the covering member and the reinforcing core member, and has appropriate flexibility, and when a large load is applied to the buckle, the load is supported by the webbing. .

Problems to be Solved by the Invention However, in the conventional example, when a large load is applied to the buckle, the webbing stretches due to the load, but the load does not act on the covering member, and the covering member There is a possibility that slippage may occur between the buckle and the webbing, and the end portion of the covering member may partially slip out from the buckle body. There would be no problem if the covering member that slipped out when the load was removed returned to its predetermined position within the buckle, but it would not completely return to its original position due to frictional resistance. Moreover, there is a possibility that this process is repeated and the covering member falls off from the buckle.

In addition, if the covering member slips against the webbing, the webbing loop cannot be held between the buckle frame extension and the cover, causing looseness in the attachment between the buckle body and the stalk body. The webbing gets damaged and loses its strength, and the buckle becomes loose, making it difficult to put on and take off the seatbelt.

The present invention was developed in view of the above circumstances, and when a load is applied to the buckle, part of the load is transmitted to the sheathing member, the sheathing member is also stretched together with the webbing, and there is a gap between the sheathing member and the webbing. The purpose is to prevent slippage.

Means for Solving the ProblemsThe buckle stalk of the seat belt of the present invention has a buckle stalk body which is formed by covering a webbing formed with loops at both ends with a cylindrical covering member, and one side of the webbing. In a buckle stalk in which one loop is attached to a buckle body and the other loop is attached to an anchor member, the frame of the buckle body forms an extension portion extending in the direction of the buckle stalk body, and the covering member is attached to the buckle stalk. At least a portion close to the buckle body is shaped like a bellows having a plurality of unevenness, and the extension portion is inserted from the end of the covering member along the webbing, so that a part of the cover of the buckle body is attached to the buckle stalk body. It is characterized in that it covers the terminal part and fits into a recess in the unevenness of the covering member, and the webbing and the extension part are sandwiched between the cover and the covering member.

The present invention will be explained below with reference to the drawings. FIG. 1 shows the buckle stalk of the present invention. 1
is a buckle stalk body, 6 is a webbing, and loops 7 and 8 are formed at each end of the webbing. An anchor member 3 is attached to one loop 7, and the anchor member 3
is fixed to the vehicle body 10 with bolts 9. The other loop 8 is attached to the buckle body 5.

The buckle main body 5 has a frame 11,
The frame 11 has a bottom plate 12 and side plates 13 erected on both sides of the bottom plate 12. Both ends of a retaining member 14 inserted through the loop 8 of the webbing 6 are supported by the side plate 13, and the webbing 6 The frame 11 supports the load in the tensile direction applied to the frame 11. Further, the end of the bottom plate 12 is extended in the direction of the buckle stalk body 1 to form an extension 15, and the extension 15 is slightly bent to fit along the webbing 6.

A cover 16 is composed of a front cover member 17 and a back cover member 18, and the frame 11 and the engagement mechanism are housed inside the cover members 17 and 18, which are combined. An insertion opening 19 into which the tongue plate is inserted is formed at the tip of the buckle body 5, and a slide button 20 is provided as an operating member for disengaging the engagement with the tongue plate.

21 is a covering member that covers the webbing 6. The covering member 21 is a flat cylindrical member made of plastic such as polyvinyl chloride,
It is formed into a bellows-like shape with a plurality of concavities and convexities. In the present invention, it is sufficient that at least the end of the covering member 21 on the side where the buckle body 5 is attached is formed into a bellows shape, but it is preferable to form it into a bellows shape over almost the entire length as shown in the figure. . An anchor cover portion 23 is formed at the end of the covering member 21 on the side where the anchor member 3 is attached via a bellows-shaped bent portion 22. After the anchor member 3 is fixed to the vehicle body 10, the anchor cover portion 23 The anchor member 3 and the bolt 9 are covered with the anchor member 3 and the bolt 9.

The tip of the covering member 21 is inserted into the cover main body 16 through the fastening opening 24 formed in the cover 16 of the buckle main body 5, and the cover 16
The extension portion 15 of the frame 11 is inserted from the end of the covering member 21 inside. Then, the locking portion 24 of the cover 16 and the locking portion 25 protruding from the inner surface of the front cover member 17 fit into the recess 26 of the unevenness of the covering member 21, and the extension portion 15 and the webbing are connected to each other through the covering member 21. 6 is held in between.

Effects of the Invention According to the present invention, a part of the cover 16 fits into the bellows-shaped unevenness formed on the covering member 21 and holds the webbing 6 and the extension portion 15 through the covering member 21. Even when a large load is applied to the seat belt 4 and a tensile force is applied to the webbing 6, causing it to stretch, the buckle main body 5 will not hold the cover 16.
Since the covering member 21 is stretched by applying a tensile force through the webbing 6 and the covering member 21, there is no slippage between the webbing 6 and the covering member 21, and the assembled state is always maintained. Therefore, the covering member 21 will not partially slip out of the buckle body 5 or fall off from the buckle body 5, and the attachment portion between the buckle stalk body 1 and the buckle body 5 will not be rattled.

In addition, the extension part 15 of the frame 11 is the webbing 6
Since the extension part 15 and the webbing 6 are inserted into the covering member 21 along the same direction, and the extension part 15 and the webbing 6 are integrally held together by the cover 16, there is no possibility that the buckle stalk main body 1 and the buckle main body 5 are attached to each other locally excessively. It is not bent, and since the bellows-like unevenness absorbs the bending that occurs in the part, excessive strain is not applied locally. Therefore, it is not necessary to extend the reinforcing core member along the entire length of the webbing 6 as in the previous embodiment, and the buckle body 5 can always be supported correctly.

Furthermore, by forming bellows-like unevenness on the covering member 21 over its entire length as shown in the figure, the flexibility of the buckle stalk body 1 is good, and the covering member 21 is prevented from being locally concentrated. The durability of the seat belt is improved, and even when the buckle stalk main body 1 is extended due to a load being applied to the seat belt, the covering member 21 can easily follow the extension.
