Description

[Detailed Description of the Invention] The present invention relates to a three-point support type seat belt locking device for a seat whose seat back can be folded forward.

For example, in a three-point support seat belt device for the front seat installed in a vehicle, the retracting device is located near the center pillar, which is the window side of the vehicle body behind the front seat.
When the seat belt is not worn, the belt is wound up by the winding device and is positioned near the center pillar behind the front seat.

In this way, since the belt is located behind the front seat when the seat belt is not worn, it is difficult to reach the belt when the seat belt is worn, which improves the ease of wearing the seat belt.

In order to compensate for this drawback, for example, Japanese Patent Laid-Open No. 49-3316 proposes a seat back with a guide provided at the top and a belt inserted through the guide.

However, if the above-mentioned precedent is applied to a vehicle such as the front seat of a two-door car in which the seat back can be folded forward for getting in and out of the rear seat, the seat belt when the seat back is folded forward will also move forward along with the seat back. Because it is displaced to
There is a problem in that the seat obstructs getting on and off the rear seat belt.

In this type of seatbelt device, the retractor is disposed near the center pillar of the vehicle, so when the seatbelt is not worn, the seatbelt is wound up by the retractor and positioned near the center pillar.

Therefore, it is difficult to reach the belt when fastening the seat belt.
<, which impairs the ease of wearing the seat belt.

In order to compensate for this drawback, a guide is provided at the top of the seatback and a belt is inserted through the guide. However, in two-door cars, the seatbelt of the front seat does not extend to the seatbelt of the rear seat. There was a problem with getting on and off the train.

This invention was made to solve the above problems.
The following description will be made based on the illustrated embodiment.

FIG. 1 shows a two-door vehicle in which the present invention has been applied. In the figure, reference numeral 1 denotes a front seat, and its seat back 1a is configured to be able to be folded forward as shown by the two-dot chain line.

2 is a rear seat arranged behind the front seat 1; 3 is a surrounding device for a three-point support type seat belt device for the front seat; installed.

A seat belt 4 has one end connected to the winding device, and the other end is fixed to the floor on the window side of the seat by an anchor 6 through a through anchor 5 attached to the upper part of the center pillar.

7 is a through tongue slidably fitted to the seat belt 4; 8 is a buckle that engages the through tongue 7; attached to the end.

The above is a commonly used seat belt device, and the present invention has a hook 11 formed of a flexible material such as rubber on the window side side portion of the seat back 1a of the front seat 1 so as to protrude laterally toward the window side. This is what was placed.

Hereinafter, an example of the hook 11 will be explained based on FIGS. 2 and 3.

In the case shown in FIG. 2, only the hook portion 11a is formed of a flexible material such as rubber, and the hook portion 11a is fixed to the bracket 11b by baking or the like.

What is shown in Fig. 3 is the hook part 11a and the mounting part 1.
1C are both integrally formed from a flexible material.

The present invention is constructed as described above, and even if the middle part of the seat belt 4 is wound up by the winding device 3 when the seat belt is not worn, the belt 4 is hooked up as shown by the solid line in FIG. 11 and is located within easy reach of the occupant, making it easy to wear the seat belt.

Furthermore, since the hook 11 is made of a flexible material, when the seatback 1a is folded forward as shown by the two-dot chain line in FIG. Since the hook portion 11a is bent and the seat belt 4 comes off, the belt 4 is attached to the winding device 3.
is wound up and positioned as shown by the two-dot chain line.

Therefore, when the seatback of the front seat is folded forward to get on and off the rear seat 2 in a two-door car, the seat belt does not interfere with getting on and off.

Furthermore, when the seat belt 4 is pulled forward when putting on the seat belt after it has come off the hook 11, the belt contacts the hook 11, but the hook 11 bends forward and prevents the belt from moving. There are no seat belts, so you can wear your seat belt without any problems.

Further, according to the present invention, since the hook 11 is made of a flexible material such as rubber, the hook 11 is made of a flexible material such as rubber.
It has the effect that it will not damage the body or clothes even if it comes into contact with 1.

In the above embodiment, the hook is provided on the side of the seat back, but the hook may be attached to the shoulder of the seat back or the headrest.
