Abstract: A vehicle body upper structure includes a pair of first structures that constitute portions on both sides in a width direction of a vehicle body in an upper portion of the vehicle body; and a second structure that extends in the width direction and is joined at opposing ends to the first structures so as to define at least a part of a window opening, to which a windshield is attachable in cooperation with the first structures. The second structure includes a low-rigid portion that is joined to one of the pair of first structures in a first area of the one of the pair of first structures, and a high-rigid portion that is separated in distance in the width direction from the first area and that has higher rigidity than the low-rigid portion. The low-rigid portion being joined to one of the first structures via the damping material.

Abstract: There are provided a hinge pillar comprising an outer panel and an inner panel which form a closed cross section extending vertically, a hinge pillar reinforcement provided in the closed cross section, a front door attached to the hinge pillar via a pair of upper-and-lower door hinges, and a hinge bracket attaching the lower door hinge to the hinge pillar reinforcement, the hinge bracket being provided to face a front wheel in a longitudinal direction. Herein, the hinge bracket has a lower strength than a portion of the hinge pillar reinforcement where the hinge bracket is provided. Accordingly, when receiving a collision load from the front wheel, the hinge bracket changes a contact portion of the front wheel to the hinge pillar so as to guide the retreating front wheel outward in a vehicle width direction.
Abstract translation: 提供了一种铰链柱，其包括外板和内板，其形成垂直延伸的封闭横截面，设置在封闭横截面中的铰链柱加强件，通过一对上部和下部连接到铰链柱的前门， 下门铰链和铰链支架，其将下门铰链附接到铰链支柱加强件，铰链支架设置成在纵向方向上面对前轮。 这里，铰链支架的强度比铰链支柱加强件的设置有铰链支架的部分低。 因此，当从前轮接收到碰撞负载时，铰链支架将前轮的接触部分改变为铰链柱，以将后退前轮沿车宽方向向外引导。

Abstract: There are provided first and second loop-shaped structure sections which are provided to extend continuously along respective lower wall parts, respective right-and-left both side wall parts, and respective upper wall parts of a vehicle body so as to have a loop shape in a vehicle elevational view, respectively. The first and second loop-shaped structure sections are respectively positioned on an forward side and on a rearward side, in a vehicle longitudinal direction, of a damper support section. Each of these sections is formed by a closed-cross section portion where a closed-cross section is partitioned by plural members and/or a thick plate portion having a thicker plate thickness than a vehicle-body panel.
