FIG. 1 is a perspective view showing a vehicle seat and seat belt fixing structure. FIG. 2 is a perspective view showing the seat belt fixing structure. FIG. 3 is a perspective view showing a state in which the second buckle has been moved relative to the first buckle.

The seat belt fixing structure S100 of this embodiment is for fixing a seat belt. The seat belt fixing structure S100 is arranged between the center seat 92 and the rear right seat 91, for example. Note that the seat belt fixing structure according to one embodiment of the present invention may be arranged between the center seat 92 and the rear left seat.

As shown in FIG. 2, the seat belt fixing structure S100 includes a first buckle 10, a second buckle 20, a band member 30, and an attachment member 50.

A tongue plate 81a of a first seat belt 81, which is a seat belt for the rear right seat 91, is connected to the first buckle 10. The first buckle 10 includes a buckle body 11 and a support plate 12. Hereinafter, the buckle body 11 will be referred to as a first buckle body 11 to distinguish it from the buckle body of the second buckle 20. The first buckle 10 is a self-supporting buckle that is provided to be self-supporting.

As shown in FIGS. 2 and 3, the first buckle main body 11 has a slightly elongated rectangular parallelepiped outer shape. As shown in FIG. 3, the first buckle body 11 is provided with a recess 17 into which the tongue plate 81a is inserted, and a lock release button 19. The first buckle main body 11 is made of resin, for example.

The support plate 12 is provided at the bottom of the first buckle body 11, as shown in FIG. The support plate 12 is, for example, a metal plate-like member. The support plate 12 is rotatably fixed to a part of the mounting member 50. Since the first buckle main body 11 is supported by the support plate 12, the first buckle 10 can stand on its own.

The mounting member 50 has a fixed portion 51, a rising portion 52, and a rising portion 53. The mounting member 50 is, for example, a member made by bending a sheet metal member.

The fixing part 51 is a flat plate-shaped part, and is fixed to the floor surface of the vehicle, for example. The rising portion 52 extends upward from one end of the fixed portion 51. The rising portion 53 extends upward from the other end of the fixed portion 51 . An opening 53h is formed in the rising portion 53.

The second buckle 20 includes a buckle body 21 and webbing 22. Hereinafter, the buckle main body 21 will be referred to as a second buckle main body 21. The second buckle 20 is a non-self-supporting buckle that cannot stand on its own.

The second buckle main body 21, like the first buckle main body 11, is a resin member having a slightly elongated rectangular parallelepiped outer shape. The second buckle main body 21 is provided with a recess 27 into which the tongue plate 82a of the second seat belt 82 is inserted, and a lock release button 29 (see FIG. 3).

The webbing 22 is a band-shaped member that is flexible and has sufficient strength. The webbing 22 connects the second buckle main body 21 and the rising portion 53. In this embodiment, the webbing 22 is specifically passed through the opening 53h of the rising portion 53.

In the case of a configuration in which the first buckle 10 and the second buckle 20 are arranged side by side as in this embodiment, it is also possible to provide both buckles in a self-supporting manner. However, since the second buckle 20 is arranged adjacent to the center seat 92 as illustrated in FIG. 1, the second buckle 20 is A non-self-supporting configuration with webbing 22 is preferred.

(Band member 30)
The band member 30 is a stretchable band-shaped member. The band member 30 is made of plain weave rubber, for example. As the plain weave rubber, it is preferable that a material such as cloth is present in the portion in contact with the first buckle main body 11 and the second buckle main body 21, and the material has higher sliding properties than a member such as a rubber sheet. The band member 30 binds the first buckle body 11 and the second buckle body 21 together. With such a band member 30, the non-self-supporting second buckle 20 is fixed to the self-supporting first buckle 10, and the second buckle main body 21 is positioned at a predetermined position.

FIG. 4 is a schematic diagram of the first buckle main body and the second buckle main body viewed from the tip side. As shown in FIG. 4, the band member 30 includes a partition portion 31 and an outer peripheral portion 32 in this embodiment.

The band member 30 fixes the first buckle body 11 and the second buckle body 21 in such a direction that the long side 11a of the first buckle body 11 and the long side 21a of the second buckle body 21 face each other. The partition portion 31 is interposed between the first buckle main body 11 and the second buckle main body 21. The outer peripheral portion 32 surrounds the first buckle body 11 and the second buckle body 21 on the outside.

Note that in FIG. 4, for convenience of explanation, the band member 30 is not in contact with the first buckle main body 11 and the second buckle main body 21, but in reality, the band member 30 is not in contact with the first buckle main body 11 and the second buckle main body 21. It borders on 21.

As shown in FIG. 2, the band member 30 is arranged on the base end side of the first buckle body 11 and the second buckle body 21.

In this embodiment, the amount of protrusion of the first buckle body 11 from the band member 30 and the amount of protrusion of the second buckle body 21 are, for example, the same. There may be a slight difference in the amount of protrusion between the two. For example, the difference between the amount of protrusion of the first buckle body 11 and the amount of protrusion of the second buckle body 21 is the difference between the first buckle body 11 and the second buckle body 21. The protrusion amount may be less than 20% of the protrusion amount of one of the protrusions. If the amount of protrusion of the first buckle body 11 is much larger than the amount of protrusion of the second buckle body 21, it is assumed that it will be difficult for the occupant to grasp and move the second buckle body 21. In this regard, according to the above configuration, the operability of the second buckle main body 21 does not deteriorate, and the passenger can easily connect the tongue plate 82a.

The band member 30 may cover the first buckle body 11 and the second buckle body 21 entirely, but in this configuration, it becomes difficult to move the second buckle body 21 with respect to the first buckle body 11.

Therefore, in this embodiment, the band member 30 is provided so that the front end sides of the first buckle body 11 and the second buckle body 21 are exposed. As an example, the band member 30 covers a region of 30% or more and 80% or less of the entire length d1 along the longitudinal direction of the second buckle main body 21 (region corresponding to the length d2). When the length d2, which is the width of the band member 30, is longer than 80% of the total length d1, the movability of the second buckle body 21 is reduced. On the other hand, when the length d2 is less than 30% of the total length d1, the band member 30 In one form, the above range is preferable because the stability of fixation is lowered.

(How to use and effects)
The use of the seat belt fixing structure S100 configured as described above will be described below. For example, when an occupant sitting on the center seat 92 needs to move the second buckle body 21 depending on the position of the second seat belt, the occupant can rotate the second buckle body 21 with respect to the first buckle body 11. The second buckle body 21 can be moved in this direction. Specifically, the second buckle main body 21 moves forward, for example, as shown by arrow A in FIG. 3, with the base end side restrained by the band member 30 as the center of rotation.

According to such a configuration, it is possible to easily move the non-self-supporting second buckle 20, and therefore it is possible to easily connect the tongue plate 82a of the second seat belt to the second buckle 20. In particular, in the configuration of this embodiment, since the partition part 31 exists between the first buckle main body 11 and the second buckle main body 21, the part where the partition part 31 exists is connected to the second buckle main body 21. There is no contact with the first buckle main body 11. According to such a configuration, the movability of the second buckle body 21 is improved by making the partition portion 31 of a material with good sliding properties, and compared to a configuration in which hard buckle bodies slide together. , the operational feeling when moving the second buckle main body 21 is improved.

(Modified example)
FIG. 5 is a schematic diagram showing a first modification. As shown in FIG. 5, the first buckle main body 11 and the second buckle main body 21 are bound by the band member 30, and the second buckle main body 21 and the second buckle main body 21 mutually move toward the distal end side. They may be provided separately. Specifically, in this example, the surface 11s of the first buckle main body 11 and the surface 21s of the second buckle main body 21 are separated from each other in the tip side portion A1.

In this way, the configuration in which the second buckle body 21 and the second buckle body 21 are separated from each other is preferable in that the occupant sitting on the center seat 92 can easily grasp and move the second buckle body 21. . In order to reduce the contact area, at least one of the surfaces 11s and 21s may be formed in a curved shape and provided in point or line contact with each other. Although illustration of the partition part is omitted in FIG. 5, the band member 30 has the partition part as in the above embodiment.

FIG. 6 is a schematic diagram showing a second modification. This band member 130 is formed of a single elastic member. Specifically, the band member 130 includes a partition portion 131 and an outer peripheral portion 132. The partition portion 131 extends between the first buckle main body 11 and the second buckle main body 21 from a lower end 131a to an upper end 131b in the drawing. The end portion 131a is fixed to a part of the outer peripheral portion 132, for example.

The outer peripheral portion 132 extends from the end portion 131b, which is a bent portion, as a starting point and surrounds the outside of the second buckle body 21 and the first buckle body 11. As an example, the end 132a of the outer peripheral portion 132 is fixed to the end 131b by, for example, sewing. Note that although the end portion 131b in FIG. 6 is depicted with a shape assuming that the end portion 132a of the outer peripheral portion 132 is fixed, the shape of the end portion 131b bent from the partition portion 131 is limited to such a shape. Not done.

FIG. 7 is a schematic diagram showing a third modification. In the seat belt fixing structure S101 of FIG. 7, the first buckle main body 11 of the first buckle 10 and the second buckle main body 21 of the second buckle 20 are bound together by an elastic band member 230. The band member 230 is formed so that the width of the peripheral portion of the second buckle body 21 is longer than that of the above embodiment. Specifically, the band member 230 has an extension portion 233 that extends from the base end side of the second buckle body 21 toward the attachment member 50 side. Since the extension portion 233 partially covers the webbing 22, such a configuration can prevent dust and the like from adhering to the webbing 22.

Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes can be made within the scope of the gist. be. For example, all or part of the device can be functionally or physically distributed and integrated into arbitrary units. In addition, new embodiments created by arbitrary combinations of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiment resulting from the combination have the effects of the original embodiment.
