Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is, for example, a self-standing structure in which a seat belt base end portion provided in an intermediate portion of a bench seat type parallel seat of a vehicle is made to stand by a simple configuration. Regarding the mechanism.

(Prior Art) Conventionally, for example, a bench seat type parallel seat is provided in a rear seat of a vehicle of a passenger car, and a plurality of lap type seat belts dedicated to each seat are provided in the parallel seat in many cases. For this reason, one side of each of the two sets of seat belts extending toward the seats on both sides is gathered in the intermediate portion of each adjacent seat, and the seat belt base end portion is normally located at the contact portion between the seat portion and the backrest. It is attached to the attachment portion on the vehicle body side through the provided attachment portion or the contact gap.

However, in the seat belt in the middle of such a parallel seat, the metal fittings such as the buckle for fastening to the other pair of seat belts easily fall into the gap between the seat and the backrest, making it difficult to take out the seat belt. Since it is inconvenient to wear the seat, the belt at the contact part between the seat and the backrest may be provided with a self-supporting function.
Like the self-supporting buckle device of No. 6, the seat belt end is covered with a relatively rigid synthetic resin cover so that it does not bend easily and it has a self-supporting function, or it is self-supporting using a separate setting spring. It is known how to do it.

(Problems to be solved by the invention) However, the method of covering with a rigid synthetic resin cover or using a setting spring, as in the case of the conventional model No. 59-16654, has many components. Therefore, there are problems that the assembly procedure and the like become complicated and the cost becomes high.

(Means for Solving the Problem) In order to solve the problem, according to the present invention, one end of each of the two seat belts in the middle part of the seat is overlapped with the other end near the fixed end to the vehicle body and triple stitched. The seat belt is formed, and both seat belts are overlapped and sewn at a predetermined portion adjacent to the triple sewn portion.

(Function) By superposing and sewing the seat belt, the rigidity of the sewn overlapping portion of the belt itself is secured and the self-supporting function is exerted.

(Embodiment) An embodiment of the self-supporting mechanism of the seat belt end portion of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a seat belt mounting portion mounted on a seat, FIG. 2 is a perspective view showing a self-supporting mechanism of a seat belt of the present invention, and FIGS. 3 and 4 are overlapping and before sewing. It is the top view and side view which show a seat belt.

The seat belt according to the present invention is mounted on a bench seat type parallel seat provided as a rear seat of a vehicle, and is configured as a lap type belt for restraining the waist of each occupant.

That is, as shown in FIG. 1, this seat belt is a floor anchorage type in which the base end portion is attached to the floor side of the vehicle body below the seat 1, and the seat on one side supported by the mounting bracket 2 on the floor on the side of the vehicle body. The belt 3 and another seat belt 5 supported by a mounting bracket 4 in a middle portion of the vehicle body floor form a pair, and enter the seat 1a of the seat 1 and the backrest 1b through the contact gaps to restrain one occupant. Is configured to. For this reason each seat belt 3,
A binding metal fitting is provided at the tip of the seat belt 3
A tongue plate fitting (not shown) is provided on the side of the seat belt 5
A buckle fitting 6 is provided on the side.

Another seat belt 10 for restraining another occupant in the adjacent seat is also attached to the attachment fitting 4 in the middle portion.

The seat belt 10 is provided with a buckle metal fitting 11 at the front end thereof and is paired with a tongue plate metal fitting of another seat belt 8 on the right side of the seat 1 to restrain an occupant in an adjacent seat.

The seat belt self-supporting mechanism of the present invention is applied to the seat belts 5 and 10 of the mounting bracket 4 on the intermediate floor, and the two seat belts 5 mounted on the mounting bracket 4 as shown in FIG. , 10 are overlapped and sewn in a cross shape, and the self-supporting function is provided by the rigidity of the overlapped sewn portion and the rigidity of the overlapped sewn portions of the belts 5 and 10 at the base end portions.

That is, as shown in FIG. 3 and FIG. 4, one end of the belt 5 inserted into the attachment hole on the predetermined side of the attachment fitting 4 is folded back through the attachment hole of the buckle attachment 6, and near the attachment attachment 4, The belt 5 is overlapped with the other end side to form the triple sewn portion 5a, and the other belts 10 also have the triple sewn portion 10a formed in the vicinity of the fitting 4.

Further, the two belts 5 and 10 are bent in a direction intersecting with each other and overlapped and sewn, but the overlapped sewn portions 5b and 10b of the two belts 5 and 10 are respectively It is a double webbing portion adjacent to the vicinity of the triple sewn portions 5a and 10a of the belts 5 and 10.
As a result, the webbing at the same portion is quadruple stitched.
Therefore, in the vicinity of the fitting 4, the triple sewn portions 5a and 10a of the respective belts ensure rigidity, and the overlapped sewn portions 5b and 10b are quadruple stitched to ensure sufficient rigidity and provide a self-supporting function.

In this embodiment, the width of the mounting hole of the mounting member 4 is narrowed to narrow down the mounting portions of the belts 5 and 10 so that both sides of the belt are folded inward in the width direction to improve the tensile strength of the belt. At the same time, the mounting bracket 4 is downsized to save space and reduce cost. In addition, the mounting bracket 4 is provided with a positioning projection 4a so as to have a positioning function when bolted to the vehicle body side.

As described above, the self-supporting mechanism of the seat belt according to the present invention can be made inexpensive at a very simple structure, but of course the metal fitting at the end of the seat belt is not limited to the buckle metal fitting side, but may be the tongue plate metal fitting side. . Needless to say, the present invention can be applied not only to the two rows of seats as in the embodiment, but also to the seats with more seats.

(Effects of the Invention) The present invention having the above-mentioned configuration exhibits the following effects.

The rigidity of the triple sewn portion formed in the vicinity of the fixed end to the vehicle body and the rigidity of the overlapped sewn portion formed as a quadruple stitch adjacent to the triple sewn portion are sufficient for the seat belt base end portion. Independent function is given.

Since it is a very simple structure in which two adjacent seat belts are overlapped and sewn together, the structure can be constructed at low cost and the mounting work is simple.
