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.

First claim

What is claimed is:

1. A side vehicle-body structure of a vehicle, comprising:
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 of the hinge pillar;
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,
wherein said hinge bracket has a lower strength than a portion of said hinge pillar reinforcement where the hinge bracket is provided,
said hinge bracket including a front wall portion, and the front wall portion being configured to slant downward and rearward in a side view to assist in deflection of the front wheel during a front impact collision.

2. The side vehicle-body structure of the vehicle of claim 1 , wherein said hinge bracket is integrally formed at said hinge pillar reinforcement, and configured to deform when receiving a collision load from the front wheel.

3. The side vehicle-body structure of the vehicle of claim 1 , wherein said hinge bracket includes a pair of upper-and-lower lateral wall portions, the pair of upper-and-lower lateral wall portions are configured to slant rearward and downward in a side view.

4. The side vehicle-body structure of the vehicle of claim 2 , wherein said hinge bracket includes a pair of upper-and-lower lateral wall portions, the pair of upper-and-lower lateral wall portions are configured to slant rearward and downward in a side view.

5. The side vehicle-body structure of the vehicle of claim 1 , wherein said hinge bracket is formed as a separate member from said hinge pillar reinforcement and attached to the hinge pillar reinforcement, and the hinge bracket is configured to deform or be detached from the hinge pillar reinforcement when receiving a collision load from the front wheel.

6. The side vehicle-body structure of the vehicle of claim 5 , wherein said hinge bracket includes a pair of upper-and-lower lateral wall portions, the pair of upper-and-lower lateral wall portions are configured to slant rearward and downward in a side view.

7. The side vehicle-body structure of the vehicle of claim 1 , wherein said front wall portion is located above a horizontally extending center line of the front wheel.
