Description

  The present invention relates to a retractor bracket structure in which a belt retractor is disposed between a door opening and a rear quarter phosphorus hose.

In a two-door type vehicle, in the rear quarter portion, the rear wheel and the door opening are separated from each other, and there is almost no portion for gathering between the outer panel and the inner panel of the rear quarter portion. Therefore, the strength in the vicinity of the rear wheel must be ensured only by the peripheral panels such as the wheel apron and the wheel arch that are the floor parts near the rear wheel and the side members that are the side parts. Moreover, in the two-door type vehicle, the rear quarter portion has an opening for the rear quarter window, and the strength tends to be insufficient. In view of this, there has been proposed one that reinforces the rear quarter portion in a two-door type vehicle (see Patent Document 1 below).

And Further, the present invention is characterized in that an additional phosphorus hose is joined to the retractor bracket. Further, according to the present invention , the front portion of the additional phosphorus hose is joined between the wheel apron and the phosphorus hose side sill together with the retractor bracket, and the rear portion is joined to the rear quarter phosphorus hose and the quarter inner. It is characterized by that. The present invention is characterized in that the setting position of the retractor bracket and the front of the rear quarter phosphorus hose is for a means for these issues resolved.

According to the present invention, in the retractor bracket structure in which the belt retractor is disposed between the door opening and the rear quarter phosphorus hose, the retractor bracket for attaching the belt retractor is disposed between the side sill inner and the phosphorus hose side sill. By sandwiching and joining, by attaching and joining between the phosphorus hose side sill and the wheel apron, by attaching the retractor bracket as a stiffening member spanning from the side sill inner to the wheel apron , By using the retractor bracket itself as a stiffening member, the rear quarter part of a two-door vehicle, which tends to be insufficient in strength, is effectively reinforced with a minimum of light weight parts without installing a special stiffening member. It becomes possible. In addition, the load at the time of seat belt tension can be efficiently distributed to the wheel apron that is the floor part, the side sill that is the side part, etc., and the tensile load of the seat belt can be increased, and the assembly composed of these parts Buckling can be suppressed, and the impact resistance load can be increased. In addition, the movement of the retractor bracket with respect to the tensile load during belt tension can be effectively suppressed at the peripheral panel.
