Abstract

To provide a vehicle body upper structure, the purpose of which is to reduce the weight of the vehicle body and improve the torsional rigidity and side impact performance of the vehicle body. The upper structure of the car body includes: a roof (2); a roof beam (3), which extends along the width direction of the vehicle; and roof rails (4) located on the left and right sides, which extend along the Extending in the front-to-rear direction, the roof cross member (3) and the roof rail (4) are connected to each other by first reinforcement members (8), each first reinforcement member (8) being arranged from the vehicle width of the roof cross member (3) to The middle part of the direction extends to a corresponding one of the roof rails (4) located on the left and right sides along the inclined direction, and each first reinforcement member (8) is arranged on the roof rail ( 3) in the vehicle front side region (R1) or the vehicle rear side region (R2).

Description

technical field [0001] The invention relates to the superstructure of a vehicle body. Background technique [0002] Conventionally, a technique for reducing the weight of a vehicle body by molding a roof at the upper portion of the vehicle body using a resin material is known. Generally, the roof of the upper part of the vehicle body greatly contributes to the torsional rigidity of the vehicle body and the performance of the vehicle body at the time of side collision. In addition, plates made of resin materials have poor mechanical properties compared to steel plates. Therefore, in a vehicle using a resin roof, the torsional rigidity of the vehicle body and the performance of the vehicle body at the time of a side collision deteriorate. [0003] Also, as means for reducing the weight of the vehicle body, a technique for reducing the weight of the vehicle body by reducing the thickness of the steel plate used for the roof of the upper portion of the vehicle body is known. ...
