Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting a belt anchor on a rear panel of an automobile.

[0002]

[Prior art]

 In automobiles, a belt anchor (child belt anchor) is attached to the rear panel that forms a substantially horizontal portion that extends from the upper end of the rear bulkhead that rises almost along the back of the backrest of the rear seat toward the rear (for example, actual opening). See Japanese Patent Publication No. 60-149476 and Japanese Utility Model Publication No. 1-279090).

A conventional belt anchor attachment portion generally has a structure as shown in FIG. That is, a reinforcement b is formed by bulging a seat surface portion c for attaching a belt anchor, which has a substantially hat-shaped cross-section and is joined to the lower surface of the rear panel on a part of the bottom surface of the rear panel a. A belt anchor mounting nut e is fixed to the lower surface of the surface portion c via a reinforcing nut plate d, and a belt anchor f is mounted on the upper surface of the rear panel a by tightening a bolt g and a nut e.

[0004]

[Problems to be solved by the device]

 A torsion bar i for urging the trunk lid in the opening direction passes through in the lower part of the rear panel a in the vehicle width direction. The bottom of the reinforcement b is used for hooking the torsion bar in addition to the belt anchor. Although the bracket h is fixed by welding, conventionally, as shown in FIG. 3, the nut anchor d and the nut e for attaching the belt anchor and the bracket h for hooking the torsion bar are independently located at relatively close positions. Since it is fixed to the reinforcement b, there is a problem that the number of mounting steps increases. Also, since the bracket h cannot be made extremely small in the height direction due to press molding, the position where the torsion bar i passes is considerably lower than the rear panel a, which not only greatly affects the capacity of the trunk room but also the trunk lid. There is also a problem that the appearance in the trunk room is not very good when opened.

The present invention aims to solve the above conventional problems.

[0006]

[Means for Solving the Problems]

 According to the present invention, in the belt anchor mounting portion of the rear panel as described above, a seat surface portion for mounting the belt anchor and a longitudinal bead continuous with the seat surface portion are provided on the bottom surface of the reinforcement joined and fixed to the lower surface of the rear panel. A bolt insertion hole is provided on the upper mounting surface of the bracket for hooking the torsion bar, and a nut is fixed to the lower surface of the mounting surface so that its center coincides with the center of the bolt insertion hole. It is characterized in that it is joined and fixed to the lower surface of the bearing surface portion of the reinforcement, and the belt anchor is attached by screwing and tightening a bolt into the nut.

[0007]

[Action]

 By adopting the above configuration, the mounting surface of the hooking bracket of the torsion bar that urges the trunk lid in the opening direction also functions as the nut plate for reinforcing the belt anchor mounting part, and the number of parts is reduced. It is possible to reduce the number of installations and the number of installation steps, and the belt anchor load and the reaction force of the torsion bar are all effective on the front and rear closed cross-sections formed at the front and rear ends of the rear panel through the beads of the reinforcement. Are dispersed, and strength and rigidity can be improved. Furthermore, the groove for hooking the torsion bar of the bracket is positioned higher than the conventional one by the height of the seating surface upward bulging with respect to the bottom surface of the reinforcement, so that the torsion bar can be passed closer to the rear panel than before. Therefore, it is possible to increase the capacity of the luggage compartment and improve the appearance of the luggage compartment when the luggage compartment lid is opened.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a rear panel, and front and rear portions of the rear panel 1 have front and rear closed cross-section portions 2 and 3 formed by a front reinforcement 11 and a rear reinforcement 12 in a left-right direction. The left and right ends are connected to the side structure of the vehicle body. A trapezoidal bulging portion 4 is formed to bulge upward at a position slightly rearward of a substantially central portion of the rear panel 1 in the vehicle width direction, and a mounting hole 4a for a belt anchor to be described later is formed in the trapezoidal bulging portion 4. It is provided. Reference numeral 4b is a through hole of the rear wiper shaft provided in the trapezoidal bulge portion 4.

Reference numeral 5 is a reinforcement having a substantially hat-shaped cross section, which is composed of a bottom surface 5a, vertical surfaces 5b on both sides, and a flange portion 5c at the upper end of the vertical surface 5b. The portion 5c is bonded and fixed to the lower surface of the rear panel 1, and the front and rear ends of the reinforcement 5 are joined to the front and rear closed cross-section portions 2 and 3, respectively.

On the bottom surface 5a of the reinforcement 5, a seat surface portion 51 for attaching a belt anchor is formed so as to bulge upward, which is joined to the lower surface of the peripheral portion of the mounting hole 4a of the trapezoidal bulging portion 4 of the rear panel 1. At the same time, a bead 52 is formed in the longitudinal direction so as to bulge upward continuously from the seat surface portion 51. Then, the seat surface portion 51 is provided with a mounting hole 51a that matches the mounting hole 4a.

Reference numeral 6 denotes a bracket for hooking the torsion bar 7. The bracket 6 has a vertical wall in the front-rear direction in which a groove 61 for hooking a torsion bar is formed as usual, and an upper edge, a front edge and a front edge of the vertical wall. It is composed of a flange portion formed on the lower edge, and the upper edge flange portion is used as a mounting surface 62 for the reinforcement 5. In the present invention, the mounting surface 62 of the bracket 6 is used for the belt anchor mounting portion. The structure is also used as a reinforcing nut plate.

That is, the mounting surface 62 of the bracket 6 is provided with a bolt insertion hole 62a, and the nut 8 is welded and fixed to the lower surface of the mounting surface 62 so that the center of the bolt insertion hole 62a is aligned with the bolt insertion hole 62a. The bracket 6 is attached to the reinforcement 5 by welding the attachment surface 62 to the lower surface of the seat surface portion 51 so that the centers of the attachment holes 4a and 51a and the bolt insertion hole 62a coincide with each other. Then, the belt anchor 10 is applied from above the rear panel 1 and the bolt 9 is screwed into the nut 8 and tightened, whereby the belt anchor 10 is mounted on the trapezoidal bulge portion 4 of the rear panel 1.

With this configuration, the mounting surface 62 of the bracket 6 serves as a nut plate for reinforcing the belt anchor mounting portion, and the nut plate (indicated by d in FIG. 3) that was conventionally required as an independent component. Can be omitted, the number of parts can be reduced and the man-hours for welding can be reduced, and the belt anchor load and the torsion bar reaction force can be reinforced by the beads 52 in the longitudinal direction. It is effectively distributed to the front and rear closed cross-sections 2 and 3 of the rear panel through the stiffened reinforcement 5. Further, since the bracket 6 is attached to the seat surface portion 51 that is bulged and formed above the general surface of the bottom surface 5a of the reinforcement 5, even if the vertical dimension of the bracket 6 itself is the same as the conventional one, The amount of protrusion of the bracket 6 into the trunk room is reduced by the amount of upward bulging of the seat surface portion 51 compared to the conventional one, and the layout of the torsion bar 7 for urging the trunk lid in the opening direction is moved a lot larger than the conventional one. It is possible to increase the internal capacity and improve the appearance when the trunk lid is opened.

FIG. 2 shows another example of the bracket 6, which includes a vertical wall in the vehicle width direction in which two upper and lower groove portions 61 are provided, and a mounting surface 62 in which the upper end of the vertical wall is bent forward. An example of the substantially L-shaped bracket 6 is shown. Reinforcing ribs are formed by bending at the left and right ends of the vertical wall and the mounting surface 62.

Also in the bracket 6 shown in FIG. 2, as in the embodiment of FIG. 1, the mounting surface 62 is provided with a bolt insertion hole 62a, and the nut 8 is located at the center of the lower surface of the mounting surface 62. It is welded and fixed so as to coincide with the center of 62a. Then, the mounting surface 62 is attached to the lower surface of the seat surface portion 51 of the reinforcement 5 shown in FIG. 1 by joint welding so that the centers of the mounting holes 4a and 51a and the bolt insertion hole 62a are aligned with each other, and the bracket 6 is mounted to the reinforcement 5. As in the case of FIG. 1, the belt anchor 10 is attached by screwing and tightening the bolt 9 and the nut 8 so that the mounting surface 62 of the bracket 6 also serves as a nut plate for reinforcing the belt anchor mounting portion. It has exactly the same operation and effect as the case of 1.

The bracket 6 is not limited to the one shown in FIGS. 1 and 2, but any bracket having at least a groove for hooking the torch bar and having a mounting surface that can also serve as a nut plate is adopted. it can.
