Problems solved by technology

[0009] However, even when the rear pillar reinforcement is provided and the vehicle body rigidity around the front door opening is enhanced as shown in the body side structure disclosed in the literature, the vehicle body rigidity around the rear door opening is still insufficient.
[0010] In particular, the upper edge of the rear door opening is connected to the roof plate, but the roof plate is a flat plate, so the initial rigidity is low, and when the vehicle body rigidity of the upper edge portion of the rear door opening is low, there will be such a problem that, For example, in a crash, the upper edge portion of the rear door opening tends to bend and deform along with the roof panel
In this case, it may make it difficult to open and close the rear doors

Embodiment Construction

[0019] Embodiments of the vehicle body side structure of the present invention will be described below with reference to the drawings.

[0020] First, a first embodiment will be described.

[0021] With reference to Fig. 1, there is shown among the figure the exploded structural view of a pair of right and left side body parts 1, 1 of the passenger car of sedan type with front door and rear car door (all not shown), the following will be based on this The views describe the body side structure of the first embodiment of the present invention. Incidentally, the vehicle body structure (not shown) of the left part and the vehicle body structure of the right part are symmetrical with respect to the center of the vehicle.

[0022] The body side 1 is provided in such a way that the body side inner part 20 is joined to the vehicle inner side of the body side outer part 10 as an exterior member and forms a closed sectional structure, and furthermore, the body side reinforcement 30 is...

Abstract

In a side body structure, a front reinforce is provided between a side body outer panel and a side body inner panel and also, a rear roof side reinforce is provided so as to couple the front reinforce to a rear pillar reinforce along the upper edge of an opening of a rear door, and vehicle body rigidity of the periphery of the opening of the rear door as well as the periphery of an opening of a front door is enhanced.

Description

[0001] Cross References to Related Applications [0002] This non-provisional application refers to the subject matter of Patent Application No. 2003-307457 filed in Japan on Aug. 29, 2003, from which this application claims priority. technical field [0003] The present invention relates to a vehicle body side structure, and more particularly, to a technique for enhancing rigidity of a vehicle body of a vehicle having a front door and a rear door opening periphery and a rear door opening periphery. Background technique [0004] Generally, the body side of a vehicle is constructed such that a body side inner panel is joined to an inner side of a vehicle body side outer panel as an outer panel, these body side outer panels and the body side inner panel form a closed sectional structure, and secure the vehicle. rigidity. [0005] However, in a vehicle such as a passenger car having front doors and rear doors like a four-door vehicle, the opening of the front door and the open...
