In this type of seat belt anchor plate anti-rotation device, as conventionally shown in FIGS. 4 and 5, the vehicle body side plate a is embossed on both sides of the anchor plate b clamped to the vehicle body side plate a. c to form the embossed c
Therefore, it is known that the anchor plate b is prevented from running around when the anchor plate b is finally tightened.

[Problems to be solved by the device]

In the conventional seat belt anchor plate anti-rotation device, the embossments formed on the vehicle body side plates on both sides of the anchor plate clamped to the vehicle body side plate are formed in a spherical shape as a whole, and the flat surface of the vehicle body side plate is formed. Since the embossing base from the to the spherical surface is formed into a concave curved surface, when the anchor plate is tightened to the vehicle body side plate by bolting, the contact of the anchor plate with the embossing at the time of final tightening becomes point contact, and Since the contact part becomes the concave curved surface part of the embossing base, stress concentration occurs at the point contacting part of the embossing base, and at the point contacting part, the anchor plate is tightened while riding on the concave curved surface of the embossing base. This not only causes loosening of the anchor plate tightening part over time, but also during sudden braking of the vehicle. The stress concentration embossed portion is occurring by the impact force applied to the fastening portion of the anchor plate at the time of collision, which also in the time there is a problem that causes deformation of the embossed portion.

The present invention solves the above-mentioned problems of the prior art.The present invention straddles the vehicle body side plate and the vehicle body lower side component plate as a means for preventing the anchor plate from running around when the seat belt anchor plate is finally tightened to the vehicle body side plate. By using the trim cover mounting bracket that is firmly fixed, it is not necessary to specially provide anchor plate anti-rotation means, and the straight wall of the bracket can ensure the anchor plate anti-rotation. At the same time, it is an object of the present invention to provide a seat belt anchor plate anti-rotation device capable of increasing the rigidity of the anchor plate tightening portion.

[Means for Solving the Problems]

In order to achieve the above object, in the seat belt anchor plate anti-rotation device of the present invention, the vehicle body side plate and the vehicle body lower side component plate are coupled by a fastening metal together with the anchor plate located inside the vehicle body side plate. The trim cover mounting bracket is fixed to the right side portion of the anchor plate across the vehicle body side plate and the vehicle body lower side component plate.

[Action]

The anti-rotation device for the seat belt anchor plate configured as described above, as a means for preventing the anchor plate from whirling at the time of final tightening of the seat belt anchor plate with respect to the vehicle body side plate,
Since the trim cover mounting bracket fixed across the vehicle body side plate and the vehicle body lower side component plate is provided in the vicinity of the right side portion of the anchor plate, the trim cover mounting bracket is used as a rotation stop means for the anchor plate. By using it, it is not necessary to specially provide a means exclusively for preventing the anchor plate from rotating, and since it is not necessary to process the vehicle body side plate near the tightening portion of the anchor plate, it is possible to perform sudden braking or collision of the vehicle. Since stress concentration due to the impact force applied to the tightened portion of the anchor plate is not caused, local deformation in the vicinity of the tightened portion of the anchor plate does not occur.

Also, since the straight wall end face of the trim cover mounting bracket can be used as a rotation stop means for the anchor plate, the side end face of the anchor plate should make surface contact with the straight wall end face of the bracket when the anchor plate is finally tightened. Therefore, the anchor plate can be surely prevented from rotating.

Further, the trim cover mounting bracket is fixed over the vehicle body side plate and the vehicle body lower side component plate, and further, the vehicle body side plate and the vehicle body lower side component plate are coupled at a position close to the fastening portion of the anchor plate. Since the fastening portion of the anchor plate is reinforced by the bracket, the rigidity of the fastening portion of the anchor plate can be improved.

〔Example〕

An embodiment will be described with reference to the drawings. The embodiment relates to a detent device for a seatbelt anchor plate of a rear seat, as is apparent from an adaptation point P in FIG.
An anchor plate 1 is connected to an end portion of a seat belt 2. The anchor plate 1 is a wheel house plate 4 composed of an inner plate and an outer plate, which are lower-body constituting plates of a vehicle body at a lower end portion inside a vehicle body side plate 3. Of the wheel house plate 4 is welded to the outer plate of the wheel house plate 4 from the upper part thereof to the flange 5 by welding. The lower part of the outer plate is welded to the lower end of the vehicle outer plate 8, and the lower part of the inner plate of the wheel house plate 4 is welded to the side part of the floor plate 9.

Then, on the right side of the anchor plate 1, there is provided a trim cover mounting bracket 10 whose cross section is formed in an inverted L shape and whose side end face is close to the side end face of the anchor plate 1 (see FIG. 2). Shows the positional relationship between the anchor plate 1 and the trim cover mounting bracket 10 on the right inner side of the vehicle body, and also shows the positional relationship of the trim cover mounting bracket 10 'on the left inner side of the vehicle by phantom lines. ), One end of the trim cover mounting bracket 10 is welded to the inner side surface of the vehicle body side plate 3, and the other end is welded to the upper side of the inner side plate of the wheel house plate 4, respectively, when the anchor plate 1 is finally tightened. Is the side edge of the anchor plate is the trim cover mounting bracket
By making surface contact with the end surface of the straight wall 10 of the anchor plate 1, the anchor plate 1 can be reliably prevented from rotating, and further, the trim cover mounting bracket 10 and the vehicle body side plate 3 and the wheel at the position close to the tightening portion of the anchor plate 1 can be used. By connecting the house plate 4 to the inner plate, the rigidity of the fastening portion of the anchor plate 1 can be improved.

Although the trim cover mounting bracket 10 is formed to have an inverted L-shaped cross section in the embodiment, this shape is not uniform, and effectively receives the side end surface of the anchor plate 1 and the trim cover. The trim cover mounting bracket 10 is welded to the inner side plate of the wheel house plate 4 in the embodiment, as long as 11 is attached by a connecting means such as a mounting screw 12. In some cases, it does not necessarily have to be welded to the wheel house plate 4 as long as it is welded to the vehicle-body lower side component plate that can increase the rigidity of the fastening portion of the anchor plate 1.

[Effect of device]

The present invention is configured as described above, and includes a vehicle body side plate and a vehicle body lower side component plate as means for preventing the anchor plate from rotating around when the seat belt anchor plate is finally tightened with respect to the vehicle body side plate. Since the trim cover mounting bracket fixed across the anchor plate is provided close to the right side of the anchor plate, it is possible to use the trim cover mounting bracket as a means to prevent the anchor plate from rotating. Since it is not necessary to provide a special means for stopping, simplification of production can be achieved, and it is possible to prevent the anchor plate from rotating by the surface contact with the side end surface of the anchor plate by the wall end surface of the trim cover mounting bracket. As a result, it is possible to ensure the rotation stop at the final tightening of the anchor plate.
