Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adjuster for adjusting the webbing length of a seat belt, and more particularly to a structure for preventing the end of the webbing from coming out of the adjuster.

[0002]

[Prior Art]

 Conventionally, as a means for preventing the end of the webbing from slipping out of the length adjuster in the seat belt device, the one disclosed in Japanese Utility Model Application Laid-Open No. 2-125466 is known. That is, (a) an end portion of the webbing is bent and sewn, (b) a needle-like projection penetrating the end of the webbing is provided on the inner surface of the webbing insertion hole, and the protruding portion is crushed (plastic processing), (c) webbing The end of the webbing of the length adjuster is welded to the inner surface of the insertion hole (heat welding process), (d) the end of the webbing is made to be an enlarged part larger than the webbing end insertion hole (thermal deformation process), and so on. Are known.

[0003]

[Problems to be solved by the device]

 However, the method of bending and stitching the ends of the webbing is troublesome and troublesome. In addition, in methods such as plastic working, heat welding, and heat deformation working, it is necessary to strictly control the processing dimensions and temperature, which makes the work troublesome and requires an expensive processing machine. There is a problem. In view of the above-mentioned problems in the prior art, the present invention provides a seat belt webbing length adjuster that can reliably prevent the webbing terminal from being pulled out and that is easy to assemble. It is intended.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, the seat belt webbing length adjuster is composed of an adjuster main body having a webbing insertion hole formed therein and a sandwiching plate locked to the adjuster main body. The end of the drawn-out webbing is clamped and fixed between the adjuster body and the clamp plate.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an assembled state of a seat belt webbing length adjuster according to the present invention, FIG. 2 is an exploded perspective view of the webbing length adjuster, and FIG. 3 is a perspective view of a holding plate viewed from the back side. FIG. 4 is a perspective view showing another embodiment of the seat belt webbing length adjuster according to the present invention, and FIG. 5 is a sectional view showing its assembled state.

As shown in FIGS. 2 and 3, a webbing length adjusting tool (hereinafter referred to as “adjusting tool”) 1 includes an adjusting tool body 3 having a webbing insertion hole 2 and an adjusting tool body 3. The holding plate 4 is locked. The sandwiching plate 4 is provided with locking step portions 5 and 6 at both ends thereof, and the locking step portions 5 and 6 are locked to the locking claws 7 and 8 provided at both ends of the adjuster body 3. By doing so, the holding plate 4 can be assembled to the adjuster body 3. Further, a rising portion 9 is formed on one side of the adjuster body 3, and locking holes 10 and 11 are formed in the rising portion 9. On the other hand, the holding plate 4 is provided with locking pieces 12 and 13 on one side thereof, and by holding the locking pieces 12 and 13 in the locking holes 10 and 11, the holding plate 4 is held. The adjustment tool body 4 of FIG. 4 can be more securely attached to the adjustment tool body 3. A plurality of protrusions 14 are provided in a zigzag pattern on the back surface of the holding plate 4. On the other hand, the adjuster body 3 is provided with an escape groove 15 at a position facing the protrusion 14, and when the end 16a of the webbing 16 is sandwiched between the adjuster body 3 and the sandwiching plate 4, the protrusion 16 is projected. 14 penetrates the end 16a of the webbing 16 up and down, and its tip is located in the escape groove 5b (see FIG. 1).

As shown in FIG. 1, the webbing 16 having one end fixed inside the automobile is inserted into the webbing insertion hole 2 of the adjusting tool 1 and wound around the bar 18 in the tongue 17, and thereafter, The terminal 16a is fixed to the adjusting tool 1. Here, the method of fixing the terminal 16a of the webbing 16 to the adjuster 1 is as follows. First, the end 16a of the webbing 16 is placed on the upper surface of the adjuster body 3, and then the holding plate 4 is pressed from above the adjuster body 3. Then, the locking step portions 5 and 6 of the holding plate 4 are attached to the locking claws 7 and 8 of the adjusting tool body 3, and the locking pieces 12 and 13 of the holding plate 4 are attached to the locking holes 10 and 11 of the adjusting tool body 3. Each of them is locked and the holding plate 4 is assembled to the adjuster body 3. Then, when the holding plate 4 is assembled by pressing it from above the adjuster body 3, the plurality of protrusions 14 provided on the back surface of the holding plate 4 vertically penetrate the end 16a of the webbing 16 and the leading end thereof escapes. Located in the groove 15. As a result, the end 16a of the webbing 16 is securely clamped and fixed between the adjuster body 3 and the clamping plate 4, so that the end 16a of the webbing 16 can be reliably prevented from coming off. Further, since the end 16a of the webbing 16 can be clamped and fixed only by locking the clamp plate 4 to the controller main body 3 in this manner, the assembling work of the controller 1 becomes very easy.

In the above embodiment, the projection 14 is provided on the back surface of the sandwiching plate 4, but the projection is not limited to the projection 14 and may be a ridge. May only be applied with an adhesive. Further, in the above embodiment, the protrusion 14 is provided on the back surface of the holding plate 4, but the present invention is not limited to this configuration, and it may be provided on the front surface of the adjuster body 3. Further, in the above embodiment, the adjusting tool main body 3 and the sandwiching plate 4 are provided separately, but it is not always necessary to provide them separately, and as shown in FIGS. The holding plate 4 may be integrally formed of synthetic resin via the thin hinge portion 19.

[0009]

[Effect of the device]

 As described above, according to the present invention, the webbing length adjuster for the seat belt is configured by the adjuster body having the webbing insertion hole and the sandwiching plate locked to the adjuster body. Since the end of the webbing pulled out from the hole is clamped and fixed between the adjuster body and the clamp plate, the end of the webbing can be securely fixed to the webbing length adjuster, and as a result, There is an excellent effect that it is possible to reliably prevent the webbing terminal from being pulled out. Further, since the end of the webbing can be clamped and fixed only by locking the clamping plate to the adjuster body, there is an excellent effect that the assembling work of the webbing length adjuster becomes very easy.
