Description

  The present invention relates to the technical field of automobiles, and more particularly to a vehicle body reinforcing member and a racing harness (four-point harness, etc.) that are required when running a competition using a commercial vehicle.

  A so-called “three-point seat belt” is provided in advance in the front seats of automobiles that are generally marketed (see Patent Documents 1 and 2). FIG. 3 shows a schematic configuration of the three-point seat belt described in these patent documents.

There are various three-point seat belt mounting configurations.
1, one end passing through the shoulder side is connected to the B pillar side and one end passing through the waist side so as to pass through the attachment / detachment holder 32 installed on the vehicle body center side (floor tunnel 14 side) of the seat 10. Is directly fixed to the vehicle body floor 10 by bolts 16.

  However, when performing sports such as competitions, the three-point seat belt does not necessarily hold the body sufficiently, and various operations cannot be performed accurately, and safety such as a collision cannot be sufficiently secured. is there.

  Therefore, when performing a competitive running or the like, a racing harness (a four-point seat belt, a five-point seat belt, or the like) may be used instead of the three-point seat belt provided in advance in the vehicle. Generally, a commercially available vehicle is not provided with a fixing part (for example, an eyebolt or an L-shaped stay provided with a hole) for attaching the racing harness. It is necessary to provide a part.

  As the technique, for example, the racing harness is attached by replacing the bolt 18 fixing the seat 20 to the vehicle body floor 10 or the bolt 16 fixing the three-point seat belt 30 to the vehicle body floor 10 with an eyebolt or the like. Although it is theoretically possible to use a fixed portion for this purpose, in recent years, there is no room in the vehicle, and it is often difficult to replace existing bolts with eyebolts. In particular, it is difficult to replace the seat fixing bolt 18 with an eyebolt because of the location and orientation of the seat fixing bolt 18.

  In such a case, the present situation is that an eye bolt or the like is fixed while unavoidably making a hole in the floor and reinforcing it with an auxiliary plate to ensure sufficient strength.

  On the other hand, it is a well-known fact that a higher vehicle body rigidity is desirable from the viewpoint of ease of vehicle body control and the like when performing competitions and the like.

  However, for example, the act of making a hole in the floor of a vehicle that has just been purchased is not a little hesitant from the viewpoint of lowering the vehicle value. However, on the other hand, with appropriate attachment (for example, attachment using a thin bolt existing in the vehicle), sufficient attachment strength of the racing harness cannot be ensured in the unlikely event.

  Accordingly, the present invention has been made to solve the above-described problems, and can attach the racing harness without making a hole in the vehicle floor, and at the same time, improve the rigidity of the vehicle body. It is an object of the present invention to provide a vehicle body reinforcing member with a racing harness fixing portion that can be used.

  In order to solve the above-described problems, the present invention provides a first stay that can be fastened together with a seat fixing bolt portion located on the vehicle rear side and the vehicle center side of the bolts that fix the front seat of the vehicle to the floor. A second stay portion that can be fastened together with a three-point seat belt fixing bolt portion that fixes one end of a three-point seat belt provided in advance for a front seat of the vehicle to a vehicle body floor; A reinforcing portion that integrally connects the first stay portion and the second stay portion, and a screw hole for an eye bolt that is integrally formed on the first stay portion side.

  The present invention also includes a first stay portion that can be fastened to a seat fixing bolt portion located on the vehicle rear side and the vehicle center side of the bolts fixing the front seat of the vehicle to the floor, Of the bolts fixing the front seat to the floor, a second stay portion that can be fastened together with a seat fixing bolt portion located on the vehicle rear side and the vehicle outer side, the first stay portion and the second stay A reinforcing portion that integrally connects the portions, and a screw hole for an eyebolt integrally formed on the first stay portion side.

  By adopting such a configuration, the racing harness can be attached without making a hole in the vehicle body, and the rigidity of the vehicle body can be improved. Attachment portions of vehicle seats and three-point seat belts to the vehicle body floor are made with a considerable degree of strength. Therefore, high strength can be secured by fastening the stay portion together using these high strength portions.

  On the other hand, although the attachment part itself to the vehicle body floor of these vehicle seats and the three-point seat belt is secured to a considerable degree, the portion between them is not necessarily the same. For example, from the viewpoint of weight reduction, the thickness of a metal plate or the like constituting the chassis tends to be thin, and if there is a strong input from the suspension device side, twisting or the like often occurs in the vehicle body. Therefore, in the present invention, a portion where strength is secured to a considerable extent, such as a vehicle seat or a three-point seat belt mounting portion on the vehicle body floor, is actively connected by a reinforcing portion, so that a large input can be obtained. The vehicle body is prevented from being twisted, that is, the rigidity of the vehicle body is improved.

  Further, in the above, the eyebolt screw hole integrally formed may also be provided on the second stay portion side.

  With this configuration, even if the bolt on the second stay portion side cannot be simply replaced with an eyebolt or the like due to space problems, the fixing portion of the racing seat belt can be secured by screwing the eyebolt into the screw hole. Can do.

  By applying the present invention, the racing harness can be attached without making a hole in the vehicle floor, and at the same time, the rigidity of the vehicle can be improved.
