Description

[Detailed Description of the Invention] The present invention relates to a so-called three-point seat belt device for fastening the shoulders and waist of a passenger seated in an automobile.

As a three-point seat belt device, as shown in Figure 1,
One end of the seat belt 1 is fixed in the trim 8 at the lower side of the vehicle body (for example, the lower part of the center pillar) via the retractor 2, and the other end is inserted through the through hole 3 provided at the upper part of the center pillar, and then the seat belt 1 is inserted downward. For example, the tongue 5 is inserted into the seat belt 1 between the through hole 3 and the anchor 4 so that the tongue 5 can be slid on the seat belt 1.
By engaging and locking the buckle 6 attached to a vehicle body member (for example, the floor or a member fixed to the floor) at the lower center side of the seat 7, the seat belt 1 is attached to the shoulder and waist of the occupant as shown by the chain line. Conventionally, seatbelts 1 are of a type in which, when the tongue 5 is removed from the buckle 6, the seatbelt 1 is automatically retracted by the retractor 2 and released as shown by the solid line.

However, in the conventional seatbelt shown in the first diagram, when the seatbelt is released, the seatbelt 1 between the through hole 3 and the anchor 4 is pulled by the retractor 2, so it becomes straight and protrudes considerably into the vehicle interior. This poses a problem, especially in two-door cars, as it obstructs getting in and out of the rear seats.

Also, since the tongue 5 is inserted through the seat belt 1 so that it can freely slide, when the belt is released, it may have slipped down to almost the lowest part of the anchor 4, so it is recommended to fasten the seat belt after seating. When doing so, it is necessary to search for the location of the tongue 5, which has the disadvantage that the seat belt fastening operation becomes troublesome.

The present invention is aimed at addressing the above-mentioned conventional problems, and will be described below with reference to the embodiments shown in FIGS. 2 and 3.

In the present invention, the tongue 5 inserted into the seat belt 1 is
The structure is as shown in the figure.

That is, the tongue 5 generally has a sleeve portion 5 through which the belt 1 is inserted.
Normally, the locking portion 5b, which is inserted and locked into the buckle 6, protrudes from one end of the buckle 6, but in the present invention, as shown in FIG. It has a structure in which an insertion part 5c integrally projects from the end opposite to the part 5b.

Then, in the seatbelt release state, the insertion part 5c of the tongue 5 inserted through the seatbelt 1 is inserted into the seatbelt outlet part 8a of the trim 8 as shown in the third figure.

Then, the seat belt 1 is attached to the side wall of the vehicle body (
The seatbelt is supported almost along the pillar inner wall) 9, and the space inside the vehicle is increased compared to the conventional seatbelt that is stretched out against the side wall of the vehicle body like a bowstring, as shown by the chain line. In addition, problems such as hindering rear seat occupants from getting in and out of two-door cars can be completely prevented.

Furthermore, according to the present invention, the seatbelt is not twisted at all, whether in the used state in which the tongue is locked to the buckle or in the seatbelt retracted state in which the insertion part of the tongue is inserted into the seatbelt exit part of the trim. To maintain an accurate occupant protection function without impairing the feeling of wearing a seatbelt in a used state or the interior aesthetics in a stored state.

Furthermore, in the present invention, the tongue 5 is secured to the seatbelt exit portion 8a of the trim 8 without slipping downward, so the problem of having to search for the tongue when fastening the seatbelt is completely eliminated. This also makes it possible to simplify the belt fastening operation.
