Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure for mounting a seat belt for a vehicle, and more specifically, a three-point type of a rear seat in a rear body having a rear shelf like a notch back type. The present invention relates to a seat belt mounting structure.

[Conventional technology]

Conventionally, as a structure for attaching a seat belt for a rear seat of this kind, as shown in FIGS. 4 and 5, a rear shelf 2 fixed to a root portion of a rear pillar 1 of a rear body is provided with a rear shelf 2 of the rear shelf 2. Chevron groove 3 formed at the rear
(It forms part of the rear windshield window frame)
And a rear portion of the under panel 4 arranged on the rear surface of the rear shelf 2 form a square tubular portion 5, and the three-point seat belt 6 of the rear seat has a retractor 7 attached to a quarter inner panel (not shown). Rear shelf 2
It is inserted through the anchor 8 attached to the rear pillar 1 through the hole 2a provided in the rear pillar 1.

Further, as another conventional example, as shown in FIGS. 6 and 7, a cross member 11 is provided horizontally between both side wall portions 10 of the vehicle body behind the rear seat 9 and the seat belt is attached to the cross member 11. There is a structure with 12 attached (see Japanese Utility Model Laid-Open No. 62-10160).

[Problems to be solved by the invention]

However, in the first conventional example shown in FIG. 4 and FIG. 5, the closed cross section of the square tubular portion 5 becomes an open cross section at the hole 2a through which the seat belt 6 provided in the rear shelf 2 is inserted, and the rear pillar The strength of the connection between 1 and the rear shelf 2 is weakened, and the rigidity of the entire body is reduced. Then, in order to provide the mounting portion of the retractor 7 and the mounting portion of the anchor 8 on the rear body whose rigidity has been reduced, reinforcing members 7a and 8a are added to each mounting portion to give strength to the input of the seat belt 6. Therefore, there is a drawback that the number of assembling steps, weight and cost are increased.

Further, in the second conventional example shown in FIG. 6 and FIG. 7, since the mounting strength of the seat belt 12 is maintained only by the bending strength of the cross member 11, the safety of the occupant is surely guaranteed. There is a problem that you cannot do it.

[Means for solving problems]

The present invention has been made to solve the above-mentioned conventional problems, and by attaching a seat belt to the closed cross section of the rear shelf that also serves as the window frame of the rear window glass, the closed cross section is The purpose of the present invention is to provide a product in which the binding strength of the rear window glass is added to the bending strength of the above, and the strength against the input of the seat belt is improved, and the gist thereof is the rear window fixed to the rear pillar. Forming a square tubular section with a closed cross section that doubles as a window frame of glass, and fix the end of the seat belt to the upper surface of the bracket fixed between the square tubular section and the upper surface of the strut housing provided on the inner panel of the wheel housing. According to another aspect of the invention, there is provided a vehicle seat belt mounting structure.

〔Example〕

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the embodiment shown in FIGS. 1 to 3, in which 21 is a rear shelf,
The over panel 22, the under panel 23 arranged on the back surface of the over panel 22 and having the slit 23a formed on the front surface thereof, and the patch 24 arranged on the front side between the both panels 22, 23.
The outer ends of the members 22, 23, and 24 are fixed to the root portion of the rear pillar 25.

Then, at the rear end of the rear shelf 21, a mountain-shaped groove 22a formed at the rear end of the over panel 22, a valley groove 23b formed at the rear end of the under panel 23, and the periphery of the patch 24 are formed. When the parts are welded together, the under panel 23 and the patch 24 are fixed to each other with bolts 26 to form a square tube part 27 having a closed cross section. The mountain-shaped groove 22a of the rear shelf 21 constitutes a part of the window frame of the rear window glass 28, and the rear window glass 2 is formed on the outer surface of the mountain-shaped groove 22a.
The peripheral portion of 8 is fixed with an adhesive 29. Reference numeral 30 denotes a strut housing bracket whose upper surface provided in the center of the wheel housing inner panel 31 has a rectangular planar shape, and two female screws 30a are formed separately on the upper surface. The front side of the rear shelf 21 is fixed to the rear and side surfaces of the strut housing bracket 30.

32 is a bracket, and the seat belt 33 is on the front side of the bracket.
The retractor 34 for winding is fixed. The front portion of the bracket 32 is fixed to the upper surface of the strut housing bracket 30 via two legs by a male screw 35 screwed to the female screw 30a. The rear end of the bracket 32 has a slit 23a in the under panel 23.
And is fixed by the bolts 26 of the square tube portion 27.
In the figure, 36 is a rear body quarter outer panel, 37 is a quarter inner panel, and 38 is a seat back side panel.

Therefore, since the square tubular portion 27 having a completely closed cross section is formed at the rear portion of the rear shelf 21 and is connected to the rear pillar 25, a large joint rigidity is obtained and the rigidity of the rear body is improved. Then, the input to the seat belt 33 is stopped by the bending strength of the rectangular tube portion 27 having the closed cross section and the adhesive strength of the rear window glass 28.

[Effect of device]

In the vehicle seat belt mounting structure according to the present invention, as described above, the rear shelf fixed to the rear pillar is formed with the closed cross-section rectangular tube portion that also serves as the window frame of the rear window glass. Since the end portion of the seat belt is fixed to the upper surface of the bracket fixed to the upper surface of the strut housing bracket provided on the wheel housing inner panel, the bending strength of the square tube portion and the square tube portion The adhesive strength of the bonded rear wind glass is added, the strength against the input of the seat belt is improved, and the safety of the occupant can be surely guaranteed. Further, there are various effects that the reinforcing member is not necessary and the assembling process, weight and cost can be significantly reduced.
