Abstract

PURPOSE:To increase the strength around an opening of rear seat back support panel by overlapping the upper end section of rear seat back support panel and the front end section of parcel board thus forming a cross member having closed cross-section. CONSTITUTION:The front end section of parcel board 3 is folded downward to form a fixing flange 3a which is spot welded to the front face at the upper end section of rear seat back support panel 1. While the rear seat back support panel 1 is formed with an opening 2 for communicating between the cabin and the trunk room and the upper end section is folded in step to form a fixing flange 1a. Said flange 1a is spot welded to the underface of parcel board 3. Consequently, a cross member 5 having box type closed cross-section is formed at the upper end section of rear seat back support panel 1 while extending laterally thus to improve the strength around the opening 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to the structure of an automobile body, particularly to the rear part of the automobile body.
Concerning the coupling structure between the dopak support/zone and the parshell.

(Prior Art) Examples of the above-mentioned conventional vehicle body structures include those shown in FIGS. 3 to 5. That is, the rear seat pack support panel 103 is located inside the single compartment 101 and the trunk compartment 102.
In a vehicle in which the upper edge of the rear backpack support panel 103 and the downwardly bent front edge of the shell 105 are connected to each other through an opening 104, as shown in FIG. are polymerized and joined together by spot welding or the like. Further, as shown in FIG. 5, a striker 106 is attached to the inclined rear seat barracks hole 103 by a delt 107 and a nut 108, and the striker 106 has a lock built into the entire rear seat pack 109. By engaging and disengaging a mechanism (not shown), the rear seat pack 109 can be locked in the illustrated upright position, and the lock can be removed and laid down.

In addition, as a reference, the account service bulletin 1980 1
October No. 491 (BL-14) Bluebird Ul 1m
There is a structure shown on page 4 of m-motorcycle introduction ■-4. (Problems to be Solved by the Invention) However, in the conventional vehicle body structure described above, the rear seat unevenness is insufficient. -) /4'nel 103 and/
Since there is only one joint with the J-shell 105, the strength of the joint, the screw rigidity of the car body, and the strength around the opening 104 of the palm seat pack support panel 103 may vary depending on the structure and shape of the car body. Since it is not enough, the opening 10
4i cannot be made larger. In particular, if the opening 104t is made larger, rear seat parafusa vf! −) /,
? It is necessary to increase the area and plate thickness of the overlapping part between the flannel 103 and the parshell 105, so the opening 104
In order to improve only the strength around the rear seat banoksaat/arm panel 103, the thickness of the entire plate must be increased, resulting in a significant increase in weight as a whole.

In addition, it is difficult to install the striker 106t on the inclined chassis support panel 103.
When the No. 7 ascending palm seed pack 109 is locked, the load applied to the striker 106 acts on the gel) 107 in the tensile direction, so that the nut 108 is not a loose nut that is easy to loosen, but is attached to the rear seat parafusa hole knob 103. There was a problem in that the strength of the attachment part of the striker 106 had to be sufficiently increased.

This invention was made in view of these conventional problems, and its purpose is to improve the overall area and thickness of the overlapping portion of the rear seat parafuse mother panel and the pershell without increasing the overall area or thickness. The object of the present invention is to significantly increase the bonding strength of these flanges, the torsional rigidity of the vehicle body, and the strength around the rear back support/flannel opening.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, the upper end portion of the rear seat parafusachoto motherboard and the front end portion of the shell are overlapped and connected. A cross member having a closed cross-sectional shape extending from the upper edge of the opening of the rear seat parafusahoto nonel to the corner portion was formed.

(Example) Hereinafter, an example of an automobile body structure according to the present invention will be described with reference to the drawings.

In Figure 1, 1 is the rear seat pack support armpit at the rear of the vehicle. - Tohanel 1 has a single room (not shown) and a trunk room (not shown)
An opening 2 is formed for communication between the two, and the upper end thereof is bent in a step-like manner to integrally form a mounting 7 flange 1a.

In addition, the front end of the rear quad pack support/four-wall 1 has a central portion extending horizontally along the upper edge of the opening 2, and both sides thereof are bent in the direction F along the corners of the opening 2. .

A front end portion of a Tsuku shell 3 is integrally connected to an upper end portion of the rear seat parallel plate 1. That is, 4-both sides of the shell 3 are curved downward to form the recess 4;
is formed, and the front end of the shell 3 is bent in the F direction to integrally form a mounting 7 lunge 3a, which is connected to the rear seat pack sensor 1? - It is fixed to the front surface of the upper end of the tonneau arm panel 1 by spot welding, etc., while the rear seat barafsa $-) / # Attachment 7 flange 1a of the bent upper end of the panel 1 is attached to the 4- shell 30 side. They are fixed by spot welding or the like, thereby forming a cross member 5 having a cross-shaped closed cross section, extending in the transverse direction of the vehicle body, at the upper end of the rear seat panok support channel 1. Therefore, this cross member 5 can significantly improve the joint strength and the screw rigidity of the vehicle body, and since the cross member 5 extends over the upper edge of the opening 2 and the corners on both sides thereof, the periphery of the opening 2 is can significantly increase the strength of

A rear seat pack 6 (
A striker 7 (see Fig. 2) is attached to the mounting board 8 for locking the striker 7' in the upright position.
is fixed to the upper surface of the cross member 5 (ie, the upper surface of the armpit shell 3) with bolts 9 and nuts 10. A U-shaped locking member 11 is attached to the mounting board 8.
This system member 11 is locked by a locking member (not shown) built into the rear seat pack 6 when the rear seat pack 6 is in the upright position shown in the second figure. It is designed to be held in an upright position.

Like this, striker-7t-? Since the striker 5 is attached to the horizontal upper surface of the cross member 5 having a closed cross section, the attachment strength of the striker 5 can be increased, and the efficiency of the attachment work can also be improved.

Furthermore, the recesses 4 formed on both sides of the par shell 3 behind the rear seat pack 6 can be effectively used as a storage space for small luggage and the like.

(Effects of the Invention) The vehicle body structure of an automobile according to the present invention has the above-described configuration and operation, and is formed by the end portion of the rear seat back support panel and the 74-shell, and is formed by a cross member having a closed cross section in the shape of fc and Mx. It is possible to significantly improve the joint strength of these nine panels and the screw rigidity of the vehicle body, and at the same time, it is possible to significantly increase the strength around the opening of the rear seat puncture support and two panels.
