Upper vehicle-body structure of automotive vehicle provided with sun roof

Abstract

Provided is an automotive upper portion vehicle structure with a sun roof opening, which can effectively connect the upper portion of a center pillar and an end portion position of a roof reinforcement in a vehicle width direction deviate along front and rear directions, thereby realizing light weight, and great rigidity, and in particular improving the vehicle width direction rigidity as side collision resistance. A connecting reinforcement (35) interconnecting a fixing plate (33) which is a window-frame member to reinforce a sun roof opening (20) and a roof side rail (6) at a position corresponding to a center pillar is provided. The connecting reinforcement (35) is positioned forward of the roof reinforcement (21), has a specified second sectional shape, and extends in a vehicle width direction roughly horizontally. A rear edge portion of the connecting reinforcement (35) and a front edge portion of the roof reinforcement (21) are connected to each other, and an inboard edge portion of the connecting reinforcement (35) and a front edge portion of the roof reinforcement (21) are connected via the fixing plate (33).

Description

technical field [0001] The present invention relates to an upper body structure of an automobile with a sunroof. Specifically, it relates to an upper body structure of an automobile with a sunroof: There is a sunroof opening, the left and right side edges of the sunroof opening are separated from the roof sill, the center pillar extends downward from the roof sill, the rear edge of the sunroof opening is located on the rear side of the vehicle than the center pillar, and the sunroof opening A roof reinforcement member having a predetermined first cross-sectional shape extending in the vehicle width direction is provided at the immediately rear portion. Background technique [0002] Generally speaking, in a car with a sunroof, the sunroof opening is preferably opened to the upper part of the head of the front passenger. Corresponds directly to the side of the chair back, or slightly in front of it. [0003] In order to satisfy these conditions, it is difficult to connect th...

AI Technical Summary

Problems solved by technology

[0006] The proposals disclosed in this Patent Document 2 and the above-mentioned Patent Document 1 have the following advantages: it is possible to improve the connection rigidity between the upper end of the center pillar and the roof reinforcement whose position in the vehicle width direction deviates front and rear, but on the other hand, there are also the following problems: When the distance in the vehicle width direction between the roof side sill and the fixing plate as a sunroof frame member is large, deformation tends to occur starting from the above-mentioned curved portion

[0008] However, in the conventional structure disclosed in this patent document 3, the center pillar and the gusset deviate in the vehicle front-rear direction, so there is a problem that the transmission efficiency of the side impact load is poor.
