It is attached to the edge continuously.

  Such a scuff plate is an automobile such as a wagon car, for example, because a floor mat (floor cover member) arranged above the floor panel is positioned higher than the side sill, and a step part that puts a foot on getting on and off, It consists of a rising part that rises from this step part.

  Here, the anchor plate is usually arranged so that at least a part thereof is positioned below the height position of the scuff plate or the floor mat. However, the following problems occur when arranged in this way. In other words, when the occupant is restrained by the seat belt device and the frontal collision of the vehicle (vehicle collision), the occupant moves to the front of the vehicle, but the occupant is restrained by the webbing on the seat, so the webbing is moved to the front of the vehicle. There is a risk of being pulled and coming into contact with the scuff plate or the floor mat.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a seat belt device for restraining an occupant seated on a seat, including a floor panel disposed below the floor cover member. In the seatbelt mounting structure of a vehicle that is mounted on a vehicle body, the webbing is prevented from being damaged at the time of a vehicle collision when the passenger is restrained by the seatbelt device.

  Note that the seat belt mounting structure on the right independent seat 20a side is substantially the same as the above-described seat belt mounting structure on the left independent seat 21b side (the same applies to other embodiments).

-Operation of vehicle seat belt mounting structure-
Hereinafter, with reference to FIG. 4 and the like, the operation of the seat belt mounting structure when the seat belt device 30 is restrained by the occupant and at the time of a vehicle front collision will be described.

  When the vehicle 1 collides frontward, the occupant seated on the left independent seat 21b moves forward of the vehicle with inertial force. However, since the occupant is restrained by the webbing 31 on the left independent seat 21b, the webbing 31 is pulled forward of the vehicle. The end on the anchor plate 34 side is inclined obliquely inward and forward. Depending on the magnitude of the impact, the vertical plate portion 34b of the anchor plate 34 bends obliquely inward and forward from the bottom plate portion 34a (see the two-dot chain line). When the anchor plate 34 is tilted in this way, the end of the webbing 31 on the anchor plate 34 side comes into contact with the notch 13e of the scuff plate 13 from the rear side of the vehicle, and moves obliquely inward and forward while destroying the top plate 13d. (See the two-dot chain line).

  Here, in the present embodiment, the protective portion 31e is overlapped and sewn on the scuff plate 13 side surface of the lower end portion of the second webbing portion 31c of the webbing main body 31a, so that this portion has a double structure, as described above. When the anchor plate 34 is bent, the protective portion 31e is in contact with the scuff plate 13 (see the two-dot chain line), and therefore, the lower end portion of the second webbing portion 31c of the webbing body 31a that moves obliquely inward and forward (lap belt) The left end) does not directly contact the scuff plate 13.

  The operation of the seat belt mounting structure on the right independent seat 20a side is substantially the same as the above-described seat belt mounting structure on the left independent seat 21b side (the same applies to other embodiments).

-Effect-
As described above, according to the present embodiment, the webbing 31 has a webbing main body 31a for restraining an occupant, and extends downward from the webbing main body 31a and then inserted into the insertion hole 34c of the anchor plate 34. 13 is folded back to the side 13 and extends upward, and extends upward from the folded portion 31 d and is overlaid and stitched on the webbing main body 31 a so that the entire height of the scuff plate 13 is restrained by the seat belt device 30 when the passenger is restrained. The protection portion 31e is located above the position, and this protection portion 31e constitutes a webbing protection means. When the occupant is restrained by the seat belt device 30 and when the vehicle crashes, the scuff plate 13 Because it comes in contact with the seat belt with a simple structure The vehicle front collision a when restraint by location 30, the webbing 31, in particular can webbing body 31a can be inhibited from being damaged.

  By the way, in general, the anchor plate 34 is short. However, when the anchor plate 34 is short as described above, the amount of movement of the webbing 31 becomes large when the occupant is restrained by the seat belt device 30, and it is necessary to take a large space for moving the webbing. .

  Here, according to the present embodiment, since the upper end of the anchor plate 34 is positioned in the vicinity of the height position of the back surface of the scuff plate 13, the amount of movement of the webbing 31 is reduced when the seat belt device 30 restrains the occupant. The space for moving the webbing can be reduced.

  Further, since the upper end of the anchor plate 34 is positioned in the vicinity of the height position of the back surface of the scuff plate 13, the anchor plate 34 hardly appears on the surface side of the scuff plate 13, and the appearance inside the vehicle can be maintained.

  In the present embodiment, the entire protection portion 31e is positioned above the height of the surface of the top plate portion 13d of the scuff plate 13 when the occupant is restrained by the seat belt device 30. However, the protection portion 31e is the seat belt. As long as the occupant is restrained by the device 30 and abuts against the scuff plate 13 at the time of frontal collision of the vehicle, at least a part thereof is above the height position of the top plate portion 13d surface of the scuff plate 13 when the occupant is restrained by the seat belt device 30. What is necessary is just to be located.

  Further, in the present embodiment, the vertical plate portion 34b is extended to the vicinity of the height position of the back surface of the top plate portion 13d of the scuff plate 13, but it is not necessary to extend to that extent. However, the former is preferable from the viewpoint of saving space for moving the webbing and maintaining the appearance in the vehicle.

(Embodiment 2)
In the present embodiment, as shown in FIG. 8, the vertical plate portion 34 b of the anchor plate 34 extends from the bottom plate portion 34 a to a position above the height position of the surface of the top plate portion 13 d of the scuff plate 13.

  The folded portion 31d of the webbing 31 extends downward from the lower end of the second webbing portion 31c of the webbing body 31a, and then is inserted into the insertion hole 34c of the anchor plate 34 (on the opposite side to the scuff plate 13). A conventional type that is folded back to the upper side and extends upward, and is overlapped and stitched to the lower end of the second webbing portion 31c. That is, the webbing 31 is not provided with the protection part 31e as in the first embodiment. Further, the folded portion 31d is positioned above the height position of the surface of the top plate portion 13d of the scuff plate 13 when the seat belt device 30 restrains the occupant.

  The anchor plate 34 constitutes a webbing protection means for preventing the webbing 31 from coming into contact with the scuff plate 13 and being damaged when the occupant is restrained by the seat belt device 30 and the vehicle is in front of the vehicle. That is, as will be described in detail later, the anchor plate 34 comes into contact with the scuff plate 13 when the seat belt device 30 is restrained by the occupant and when the vehicle collides.

  In other respects, the configuration is almost the same as that of the first embodiment.

-Operation of vehicle seat belt mounting structure-
Hereinafter, the operation of the seat belt mounting structure when the passenger is restrained by the seat belt device 30 and at the time of frontal collision of the vehicle will be described.

  When the vehicle 1 collides with the front, the webbing 31 is pulled forward of the vehicle as in the first embodiment, and the end on the anchor plate 34 side tilts obliquely inward and forward. Depending on the magnitude of the impact, the vertical plate portion 34b of the anchor plate 34 bends obliquely inward and forward from the bottom plate portion 34a.

  Here, in the present embodiment, the vertical plate portion 34b of the anchor plate 34 is extended to a position above the height position of the surface of the top plate portion 13d of the scuff plate 13, and the anchor plate 34 is bent as described above. In this case, since the vertical plate portion 34 b contacts the scuff plate 13, the webbing 31 extending upward from the upper end portion of the vertical plate portion 34 b does not directly contact the scuff plate 13.

-Effect-
As described above, according to the present embodiment, the upper end of the anchor plate 34 is positioned above the height position of the scuff plate 13, and this anchor plate 34 constitutes a webbing protection means, and the seat belt device 30. Since the webbing 31 comes into contact with the scuff plate 13 at the time of the vehicle occupant's frontal collision, the webbing 31 is not devised in the webbing 31 and the occupant is restrained by the seat belt device 30 and the vehicle collides. Can be prevented from being damaged.

(Embodiment 3)
In the present embodiment, as shown in FIG. 9, the seat belt device 30 is arranged above the floor panel 14 and below the rear end portion of the top plate portion 13d of the scuff plate 13, and predicts a vehicle front collision or a vehicle front collision prediction. A lap pretensioner mechanism 39 is also provided, which sometimes instantly eliminates the loosening of the lap belt of the second webbing portion 31c of the webbing body 31a and enhances the occupant's restraining effect.

  The wrap pretensioner mechanism 39 includes a triangular anchor plate 34 whose upper end is located in the vicinity of the height position of the back surface of the top plate portion 13d of the scuff plate 13, and a wire member 39a having one end portion (upper end portion) connected to the anchor plate 34. And an inflator 39c installed on the floor panel 14 via a pedestal 39b. When a frontal collision of the vehicle is detected or predicted by a sensor (not shown), gas is generated in the inflator 39c, and a cylinder (not shown) into which this gas flows and the other end of the wire member 39a are connected to each other. The lap belt of the second webbing portion 31c is pulled toward the inflator 39c via the wire member 39a and the anchor plate 34 by a piston (not shown) that moves with the gas that flows in, and the occupant seated on the left independent seat 21b moves forward of the vehicle. It is designed to be suppressed from moving to.

  In other respects, the configuration is almost the same as that of the first embodiment. That is, the protection part 31e of the webbing 31 constitutes a webbing protection means. Specifically, the protective portion 31e is sewed on the scuff plate 13 side surface of the lower end portion of the second webbing portion 31c of the webbing main body 31a, and when the occupant is restrained by the seat belt device 30 and the vehicle is in front of the vehicle, The protective part 31e is brought into contact with the scuff plate 13.

-Effect-
As described above, according to the present embodiment, substantially the same effects as those of the first embodiment can be obtained.

  Further, since the wrap pretensioner mechanism 39 is provided between the floor panel 14 and the scuff plate 13, space can be used effectively.

  In addition, in this embodiment, although the protection part 31e comprises the webbing protection means, it is not restricted to this. For example, as in the second embodiment, the anchor plate 34 may constitute webbing protection means. In other words, the upper end of the anchor plate 34 is positioned above the height position of the surface of the top plate portion 13d of the scuff plate 13, and the anchor plate 34 is attached to the scuff plate when the occupant is restrained by the seat belt device 30 and the vehicle is in front of the vehicle. You may make it contact | abut.

It is fastened by fastening. FIG. 10 is a perspective view of the vehicle with the second row seat removed. In other respects, the configuration is almost the same as that of the first embodiment.

-Operation of vehicle seat belt mounting structure-
Hereinafter, the operation of the seat belt mounting structure when the passenger is restrained by the seat belt device 30 and at the time of frontal collision of the vehicle will be described.

  When the vehicle 1 collides with the front, the webbing 31 is pulled forward of the vehicle as in the first embodiment, and the end on the anchor plate 34 side tilts obliquely inward and forward. Even if the webbing 31 is pulled in this manner, the anchor plate 34 is prevented from being detached from the left center pillar 17.

  Here, in the present embodiment, the protective portion 31e is overlapped and sewn on the scuff plate 13 side surface of the lower end portion of the second webbing portion 31c of the webbing main body 31a, so that this portion has a double structure, as described above. When the vehicle 1 collides with the front, the protective portion 31e hits the scuff plate 13, so that the lower end portion (the left end portion of the lap belt) of the second webbing portion 31c of the webbing body 31a moves obliquely inward and forward. It is supposed not to hit directly.

-Effect-
As described above, according to the present embodiment, substantially the same effects as those of the first embodiment can be obtained.

  Further, since the anchor plate 34 is fixed to the vehicle inner side of the lower end portion of the left center pillar 17 in front of the left wheel house 18, the left independent seat 21b and the left center are secured when the seat belt device 30 is not restrained. A sufficient walk-through space for the occupant to move between the left door opening 12 and the third row seat can be secured between the pillar 17 and the pillar 17.

(Other embodiments)
In each said embodiment, although the scuff plate 13 comprises the floor cover member, it is not restricted to this. For example, the floor mat 11 may constitute a floor cover member. In this case, the anchor plate 34 is disposed so as to face the floor mat 11 so that at least a part of the anchor plate 34 is located below the height position of the floor mat 11.

  Moreover, in each said embodiment, although the protection part 31e and the anchor plate 34 of the webbing 31 comprise the webbing protection means, it is not restricted to this.

  For example, an anchor cover is provided on the anchor plate 34 so as to cover the scuff plate 13 side of the lower end portion of the second webbing portion 31c, and this anchor cover is used when the seat belt device 30 is restrained by an occupant and at the time of a vehicle front collision. You may comprise the webbing protection means which suppresses that the 2nd webbing part 31c lower end part (lap belt left-end part) of the webbing main body 31a contacts the scuff plate 13, and is damaged. In this way, when the passenger is restrained by the seat belt device 30 and when the vehicle collides, the anchor cover hits the scuff plate 13 and the lower end portion of the second webbing portion 31c is hardly damaged.

  Further, as shown in FIG. 12, a buffer member 19 made of an elastic body such as rubber extending in the horizontal direction is provided at the rear end edge of the top plate portion 13d of the scuff plate 13, and the buffer member 19 is provided with the seat belt device 30. The webbing protection means may be configured to prevent the lower end portion of the second webbing portion 31c of the webbing body 31a from coming into contact with the scuff plate 13 and being damaged when the vehicle is in front of the vehicle. In this way, when the passenger is restrained by the seat belt device 30 and the vehicle is in front of the vehicle, the lower end portion of the second webbing portion 31c hits the soft cushioning member 19 and is hardly damaged.
