Description

[Detailed Description of the Invention] The present invention relates to a bonding structure between a wire and a plate member, and more particularly to an anchor suitable for a seat belt.

Conventional products of this type have both sides folded back to face each other, a wire inserted into the shaped insertion hole, and swaged to integrate. It has the disadvantage that it loosens, so it is limited to low tension applications.

In addition, in order to prevent the expansion of both side pieces, it was proposed to cover the outer circumference of the pipe with a crimped pipe, and this improved the ability to withstand high tension. It is necessary to prepare a pipe of the same material, and it also requires a large press device including the additional pipe.

The present invention solves the above-mentioned deficiencies, and an example of its implementation will be described in detail below with reference to the drawings.

The drawing shows an example of a seat belt anchor, in which the plate 1 is made of metal, one half 1a has a hole 7 for the mounting shaft, the other half 1b has side pieces 2, 2, and both side pieces 2, 2. edge 2a of
In this case, the latching holes 5, 5 are formed into a suitable anchor base body A by casting or punching using a press machine.

The hooking holes 5, 5 on both end edges 2a, 2a are connected to the wire 4, respectively.
In the direction perpendicular to the X-axis of the insertion direction, that is, both side pieces 2,
2, and the depth 5b of each latching opening 5 is wider than the entrance 5a, so that a connecting piece 6, which will be described later and fits therein, can be pulled out in the Y-axis direction. There is.

The metal connecting piece 6 has a similar shape that can be fitted over both the opposing locking openings 5, 5, and specifically has a constricted part 6a facing the entrance 5a and an enlarged head facing the back 5b. 6b.

The anchor base A is formed by folding the two side pieces 2, 2 in the Y-axis direction so that the hooking openings 5, 5 are connected to each other so as to surround the insertion hole 3, and the wire 4 is inserted into the insertion hole 3. At the same time, the connecting pieces 6 are fitted over the respective latching holes 5, 5 connected in the Y-axis direction, and then swaged into a round cross-section or a hexagonal cross-section as shown in the drawings, and the side pieces 2, 2. Integrate the wire 4 and the connecting pieces 6, 6 into one.

As a result, the connecting piece 6 connects the side pieces 2, 2 so as not to expand in the Y-axis direction, and the wire 4 is tightened in the insertion hole 3 of the side pieces 2, 2, and the wire 4 and It is integrated with the anchor base A.

Further, in the above embodiment, the width of the connecting piece 6 is equal to the width of the inlet 5a.
Similarly to the width, it is also optional to roll the inner part 5b when it is crimped to fill the inner part 5b and to join the two side pieces 2, 2 together.

In this case, it is desirable to select a material for the connecting piece 6 that has lower hardness than that of the plate 1.

As described above, the present invention provides latching openings that are wider than the entrances at the adjacent edges of both pieces holding the wire, and fitting the connecting piece over these opposing latching openings. Since it is caulked to form an integral structure, even if the tensile force applied to the wire tries to pull up the both sides of the wire, the connecting piece joins the both sides of the wire and completely prevents the expansion. Therefore, the fastening force set between the wire and both side pieces at the time of caulking is maintained, and it has the characteristic of permanently enduring high tension.

In addition, the plates and the connecting pieces can be easily manufactured by pressing or molding means, etc., and are economically useful as they can be provided at low cost.
