Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in a seat belt device for protecting occupants in vehicle emergencies, and guides the middle portion of the webbing to ensure that the occupant is properly fitted with the webbing. The present invention relates to a webbing guide device that facilitates the webbing operation when wearing the webbing.

[Background Art and Issues to be Solved] Among seatbelt devices, many three-point seatbelt devices have a configuration in which one end of shoulder webbing is wound around a winding device attached to a side wall of a vehicle body.

In this seat belt device, when the occupant releases the webbing, the webbing is wound up by the winding force of the winding device, so that the tongue plate used when the webbing is worn moves toward the rear of the vehicle together with the webbing. Therefore, in order for the occupant to grasp the tongue plate and attach the webbing after seating, it is necessary to twist the upper body significantly toward the rear of the vehicle to grasp the tongue plate.

For this reason, conventionally, a long and thin ring supporting the middle part of the webbing has been attached to the seat to make it easier to attach the webbing. The frictional resistance generated at the webbing is large, and the resistance to winding the webbing after the webbing is released is large.

In consideration of the above-mentioned facts, the present invention aims to sell a webbing guide and mounting device that allows the occupant to easily put on the webbing and allows the occupant to wear the webbing in an appropriate state when wearing the webbing.

[Overview and operation of the invention] The webbing guide device is a webbing that guides and supports a continuous webbing that is fixed to a seat bag, one end is locked to the vehicle body, the other end is wound up by a take-up device, and a tongue plate is attached to the middle part. A guide device, which is formed in a vertical direction along a side surface of the seat back, and is wound around an intermediate portion of the webbing between the tongue plate and a take-up device to guide the webbing intermediate portion when an occupant wears the webbing. A first guide part, which is formed horizontally in communication with the lower end of the first guide part and faces outward in the seat width direction, and which is wound around and guided by the first guide part, is used by the occupant. The present invention is characterized by comprising a second guide part that is wrapped around and supported when the webbing is released.

As a result, when wearing the webbing, the first
The middle part of the webbing is guided by the guide part,
The webbing is attached closely to the passenger, further improving the fit and safety. When the occupant releases the webbing, the middle part of the webbing that has been wrapped around and guided by the first guide part slides under its own weight to the second guide part and is supported by the second guide part. Ru. Therefore, the intermediate portion of the webbing is located near the seat bag, making it easier for the occupant to grasp the webbing when reattaching the webbing.

In this way, not only is it easy to grip when the webbing is attached, but also the webbing is attached closely to the occupant, improving the fit and safety.

[Embodiment of the invention] FIG. 1 shows a webbing guide device 10 to which the invention is applied. An occupant sitting on the seat 12 is adapted to wear webbing 14. One end of the webbing 14 is supported to a side wall of the vehicle body (not shown) via an anchor plate 16, and the other end is supported to the side wall of the vehicle body via a winding device (not shown). In this case, the winding device winds up the webbing 14 with a biasing force, but in case of a vehicle emergency, the webbing 14
It has a built-in inertia lock mechanism that stops the drawer.

A tongue plate 20 attached to the middle portion of the webbing 14 is movable in the longitudinal direction of the webbing 14, and is adapted to be engaged with a buckle device 22 erected approximately at the center of the vehicle. As a result, the occupant seated on the seat 12 is fitted with a wrap webbing between the dang plate 20 and the anchor plate 16, and a shoulder webbing between the dang plate 20 and the winding device.

As shown in FIGS. 2 and 3, the webbing guide device 10 has a mounting hole 26 formed in a base plate 24, and is fixedly attached to the side surface of the seat 12 with screws 28 (see FIG. 1).

A U-shaped arm 30 is integrally connected at one end to the lower part of the base plate 24. This arm 30 has a guide section 32 serving as a second guide section on its inner side, and is designed to guide the intermediate portion of the webbing 14. This arm 30 has an extension 34 extending upwardly along the base plate 24 from the end opposite to the end fixed to the base plate 24, and a projection 36 protruding from the upper end of the base plate 24. A gap 38 is formed.

This extension part 34 forms a guide part 40 between it and the base plate 24, and this guide part 40 as a first guide part is continuous with the guide part 32 at one end and communicates with the outside through the gap 38. Therefore, the middle part of the webbing 14 passes through the guide part 4 through the gap 38.
0. Through this guide section 40, movement can be guided further to the guide section 32.

This webbing guide device 10 is preferably integrally molded from synthetic resin or the like to reduce the frictional force between it and the webbing 14.

Next, the operation of this embodiment will be explained.

A portion of the webbing 14 between the dangling plate 20 and a winding device (not shown) is inserted into the guide portion 32 or 40 through the gap 38.

Therefore, when the occupant sits on the seat 12 and engages the dangling plate 20 with the buckle device 22, the occupant is fitted with a three-point seat belt device.
In this state, the middle part of the shoulder webbing is placed into the guide part 40 due to the tension acting between the shoulder webbing part of the webbing 14, that is, the dang plate 20, and a winding device (not shown) (see FIG. (See webbing 14A). Therefore, the guide portion 40 is attached to the webbing 14 as shown in FIG.
A is guided substantially vertically in its cross-sectional state, and has the role of bringing the middle part of the webbing 14 attached to the passenger into close contact with the passenger, so that twisting or the like does not occur in the middle part of the webbing 14.

Therefore, when the vehicle is in an emergency situation, the webbing 14 can effectively restrain the occupant.

Furthermore, when the occupant releases the webbing 14, the dang plate 20 is attached to the buckle device 22.
All you have to do is extract it from In this case, the middle part of the webbing 14 extends from the guide part 40 to the guide part 32 as shown by the solid line in FIG. Since the dang plate 20 is in a substantially horizontal state as shown in FIG.
The webbing 14 is located close to 0, so that the webbing 14 can be easily attached even when the occupant reboards the vehicle. That is, the seated occupant can easily grasp the dang plate 20 without twisting his or her upper body significantly backwards, and the dang plate 20 can be attached to the buckling device 22.

Next, FIG. 4 shows a guide device according to a second embodiment of the present invention. In this embodiment, most of the extension part 34 and guide part 32 of the previous embodiment are removed. Therefore, the arm 30 is approximately J
It is shaped like a letter.

Although this embodiment is also provided with a guide section 32 and a guide section 40, these are different from the above embodiments.
It is in communication with the outside. However, the tension acting on the webbing 14
Alternatively, since a force acts in a direction that brings the webbing 14A or the webbing 14B into frictional contact with the arm 30, the webbing does not fall off from the guide portions 32 and 40.

[Effects of the invention] As explained above, the webbing guide device according to the invention is a continuous webbing that is fixed to the seat bag, one end is locked to the vehicle body, the other end is wound up by the winding device, and the tongue plate is attached to the middle part. A webbing guide device that guides and supports the webbing, and is formed vertically along the side surface of the seat back, and is wound around the intermediate portion of the webbing between the tongue plate and the take-up device, so that the webbing is guided and supported when the passenger wears the webbing. a first guide section that guides an intermediate portion of the webbing, and a first guide section that is connected to a lower end of the first guide section and is formed horizontally toward the outside in the sheet width direction, and that is wound around and guided by the first guide section. The present invention is characterized in that it includes a second guide part that wraps around and supports the webbing middle part when the webbing is removed from the occupant, so that when the webbing is worn, the webbing middle part is guided by the first guide part and comes into close contact with the passenger. The webbing has an excellent effect in that the webbing can be attached with improved fitting properties and safety, and when the webbing is being unattached, the webbing middle section is supported by the second guide section, making it easier to attach the webbing.
