REAR BODY STRUCTURE FOR AUTOMOBILES

摘要

Each rear pillar (4) includes a rear pillar inner panel (33) and a rear pillar reinforcement (34). The rear pillar inner panel (33) and the rear pillar reinforcement (34) each include a substantially L-shaped corner portion (C1, C2) raised toward the rear pillar inner panel (33), and a ridge portion (X1, X2). The corner portions (C1, C2) are arranged next to each other in the direction toward a reinforcement (50), and an L-shaped closed cross section (40) is formed between the corner portions (C1, C2). The reinforcement (50) is, not via the closed cross section, directly connected to the corner portions (C1, C2). An upper portion of the L-shaped closed cross section (40) is connected to a closed rear header cross section (19).

主权项

1. A rear body structure for an automobile, comprising: at a rear body,
right and left damper supports; a frame member forming a closed cross-sectional shape; and a connection member connected in a direction intersecting the frame member to transmit a load from each damper support to the frame member, wherein the frame member includes an inner panel and an outer-vehicle panel connected to the inner panel from an outside of a vehicle, the inner panel and the outer-vehicle panel each include a substantially L-shaped corner portion raised toward the inner panel, and a ridge portion formed by the corner portion and extending along the frame member, the corner portion of the inner panel and the corner portion of the outer-vehicle panel are arranged in a direction toward the connection member to form a recessed closed cross section between the corner portions, the connection member is, not via the closed cross section, directly connected to the corner portion of the inner panel and the corner portion of the outer-vehicle panel, and an upper portion of the recessed closed cross section is connected to a cross-sectional portion having a higher modulus of section than that of the recessed closed cross section.
