Description

Fixing apparatus for tongue of rear center three point type seat-belt}

The present invention relates to a tongue fixing device of the rear center three-point seat belt, and the rear center three-point seat belt must fix the tongue of the seat belt to the roof lining when not in use. In addition, there is a problem that the plastic body is broken inadvertently, which eliminates the existing fixing device, and instead of attaching a holder to the seat belt webbing on the rear of the first tongue, the rear center 3-point type can effectively fix the second tongue. The tongue belt fixing device of the seat belt.

In general, a vehicle is provided with a front seat and a rear seat, and a multi-seater vehicle such as an RV vehicle is provided with more rows of seats.

These seats consist of a seat cushion, which is a part of the occupant's seat, and a seat back, which is a part of which the back is leaned. In some cases, the upper part of the seat back is provided with a headrest that can rest against the head.

In particular, the front seat is separated into a driver's seat and a passenger seat and independently configured to adjust the height and position according to the passenger's body, while the rear seat is made of a bench type as shown in FIG. 1. have.

As shown in Figure 1, the rear seat is provided with a rear center three-point seat belt for protecting a passenger sitting in the seat back.

In addition, as shown in Figure 5, the seat belt webbing 10 of the rear center three-point seat belt is provided with two tongues (11, 12), the roof lining 17 of the upper headrest the tongue The magnet 100 which can fix the 11 and 12 is attached.

Accordingly, when the seat belt is not worn, the seat belt webbing 10 is wound by the retractor mounted on the right rear side of the seat back, and the first tongue 11 is attached to the roof lining 17 with magnets 100. It is fixed to).

On the other hand, the second tongue 12 is fixed to the vertical extension portion 300 formed in the rear of the plastic body portion 200 of the first tongue (11).

In this case, the vertical extension part 300 of the second tongue 12 is formed to have a size that fits well with the webbing hole 12a of the second tongue 12.

However, in the conventional rear center three-point seat belt, the tongues 11 and 12 are exposed under the roof lining 17, thereby causing a problem in aesthetics, and when the careless body breaks the plastic body 200. There is a problem in that noise is generated because the restraint force of the plastic body 200 is reduced.

In addition, there is a problem that the magnetism of the magnet 100 is deteriorated and the tongues 11 and 12 cannot be fixed.

Accordingly, the present invention has been made in view of the above problems, and provides a fixing device capable of fixing the rear center three-point seat belt by the holders 13 and 14, which are removable and eliminate the conventional magnet 100. The purpose of the draft is to.

Hereinafter, the features of the present invention will be described.

The present invention is fixed to the roof lining 17, the D-ring 18, the webbing guide hole (18a) is formed; Seat belt webbing (10) guided by the D-ring (18); In the rear center three-point seat belt composed of a first tongue 11 and a second tongue 12 mounted on the seat belt webbing 10, a first holder 13 is mounted on the roof lining 17. In addition, the seat belt webbing 10 of the rear of the first tongue 11 is characterized in that the second holder 14 is mounted.

In particular, the holder (13, 14) is characterized in that the support portion 15 is formed with a tongue hole (15a) and the elastic portion 16 having an elastic force.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.

1 is a perspective view shown to show a rear center three-point seat belt installed in the rear seat.

In addition, Figure 2 is a perspective view showing a tongue fixing device of the rear center three-point seat belt according to the present invention, Figure 3 shows a rear center three-point seat belt fixed to the roof lining according to the present invention 4 is a perspective view for illustrating, and FIG. 4 is a sectional view taken along the line 'A-A' of FIG.

Here, reference numeral 10 denotes a seat belt webbing.

The seat belt webbing 10 is drawn or wound along the webbing guide hole 18a formed in the D-ring 18 by the action of the retractor.

In addition, a first tongue 11 and a second tongue 12 are fitted into the seat belt webbing 10, and a second holder 14 is attached to the seat belt webbing 10 behind the first tongue 11. The second tongue 12 is restrained by the second holder 14, which is mounted.

The first holder 13 on which the first tongue 11 is restrained is fixed to the roof lining 17.

In particular, the holder (13, 14) is composed of a support 15, the tongue hole (15a) is formed, and an elastic portion 16 having an elastic force.

Next, the operation principle of the present invention having such a configuration will be described.

When the seat belt is not used, the first tongue 11 is first restrained by the first holder 13 mounted on the roof lining 17, and the seat belt webbing 10 behind the first tongue 11 is attached. The second tongue 12 is restrained by the second holder 14 mounted on the second holder 14.

At this time, the seat belt webbing 10 is tensioned by the retractor and is tightened so that the second tongue 12 is also firmly constrained to the second holder 14 by tension.

As described above, the present invention has the effect of improving the aesthetics, improving the restraint force, and all parts are made of plastic to reduce the weight compared to the conventional tongue fixing device.
