Abstract

There are provided a vehicle-body frame member forming an opening portion for entrance at a vehicle side part and a front side door provided so as to open and close the opening portion. The vehicle-body frame member comprises a side sill, the front side door comprises a door panel portion provided with an inner lower portion which overlaps with the side sill in a vehicle wide view and reinforcement portions provided at two side-portions of a peripheral part of the door panel portion which are continuous and include the inner lower portion such that the reinforcement portions overlap with the vehicle-body frame member in a vehicle side view.

First claim

What is claimed is:

1. A vehicle-body structure of a vehicle, comprising:
a vehicle-body frame member forming an opening portion for entrance at a vehicle side part; and
a side door provided so as to open and close the opening portion,
wherein said vehicle-body frame member comprises a side sill, said side door comprises a door panel portion and a reinforcement portion provided at a peripheral part of the door panel portion such that the reinforcement portion overlaps with said vehicle-body frame member in a vehicle side view, the peripheral part of said door panel portion comprises a lower-side overlapping portion which overlaps with said side sill in the vehicle side view, and said reinforcement portion is provided at two continuous side-portions of the peripheral part of the door panel portion which include said lower-side overlapping portion;
wherein said vehicle-body frame member comprises a center pillar, the peripheral part of said door panel portion comprises a center overlapping portion which overlaps with said center pillar in the vehicle side view, and said reinforcement portion is provided at said lower-side overlapping portion and said center overlapping portion of the peripheral part of the door panel portion;
wherein the reinforcement portion comprises a rear-side reinforcement portion disposed along an inner rear portion of the door panel portion which extends along a lower part of the center pillar, and a lower-side reinforcement portion disposed along an inner lower portion of the door panel portion which extends along the side sill;
wherein the rear-side reinforcement portion overlaps with a front-side center-pillar flange and a center-pillar-side wall portion of the center pillar in the vehicle side view,
wherein the lower-side reinforcement portion overlaps with an upper-side side-sill flange and a side-sill side wall portion of the side sill in the vehicle side view.

2. The vehicle-body structure of the vehicle of claim 1 , wherein said vehicle-body frame member comprises a floor cross member provided at a position which overlaps with said side sill in the vehicle side view and extending in a vehicle width direction, and said reinforcement portion is configured to overlap with said floor cross member in the vehicle side view.

3. The vehicle-body structure of the vehicle of claim 1 , wherein said center overlapping portion overlaps with a central part, in a vertical direction, of said center pillar, and said reinforcement portion provided at said center overlapping portion extends so as to include a position of the center overlapping portion which overlaps with said central part, in the vertical direction, of the center pillar.

4. The vehicle-body structure of the vehicle of claim 1 , wherein said vehicle-body frame member comprises a hinge pillar and an instrument-panel member provided at a position which overlaps with said hinge pillar in the vehicle side view and extending in the vehicle width direction, the peripheral part of said door panel portion comprises a front-side overlapping portion which overlaps with said hinge pillar and said instrument-panel member in the vehicle side view, and said reinforcement portion is provided at said lower-side overlapping portion and said front-side overlapping portion of the peripheral part of the door panel portion.

5. The vehicle-body structure of the vehicle of claim 1 , wherein said side door further comprises an impact bar attached to said door panel portion and extending in a vehicle longitudinal direction, and said reinforcement portion is configured to include an attachment portion of said impact bar to the door panel portion.

6. The vehicle-body structure of the vehicle of claim 2 , wherein said vehicle-body frame member comprises a center pillar, the peripheral part of said door panel portion comprises a center overlapping portion which overlaps with said center pillar in the vehicle side view, and said reinforcement portion is provided at said lower-side overlapping portion and said center overlapping portion of the peripheral part of the door panel portion.

7. The vehicle-body structure of the vehicle of claim 6 , wherein said center overlapping portion overlaps with a central part, in a vertical direction, of said center pillar, and said reinforcement portion provided at said center overlapping portion extends so as to include a position of the center overlapping portion which overlaps with said central part, in the vertical direction, of the center pillar.

8. The vehicle-body structure of the vehicle of claim 2 , wherein said vehicle-body frame member comprises a hinge pillar and an instrument-panel member provided at a position which overlaps with said hinge pillar in the vehicle side view and extending in the vehicle width direction, the peripheral part of said door panel portion comprises a front-side overlapping portion which overlaps with said hinge pillar and said instrument-panel member in the vehicle side view, and said reinforcement portion is provided at said lower-side overlapping portion and said front-side overlapping portion of the peripheral part of the door panel portion.

9. The vehicle-body structure of the vehicle of claim 7 , wherein said side door further comprises an impact bar attached to said door panel portion and extending in a vehicle longitudinal direction, and said reinforcement portion is configured to include an attachment portion of said impact bar to the door panel portion.

10. A vehicle-body structure of a vehicle, comprising:
a vehicle-body frame member forming an opening portion for entrance at a vehicle side part; and
a side door provided so as to open and close the opening portion,
wherein said vehicle-body frame member comprises a side sill, said side door comprises a door panel portion and a reinforcement portion provided at a peripheral part of the door panel portion such that the reinforcement portion overlaps with said vehicle-body frame member in a vehicle side view, the peripheral part of said door panel portion comprises a lower-side overlapping portion which overlaps with said side sill in the vehicle side view, and said reinforcement portion is provided at two continuous side-portions of the peripheral part of the door panel portion which include said lower-side overlapping portion;
wherein said vehicle-body frame member comprises a hinge pillar and an instrument-panel member provided at a position which overlaps with said hinge pillar in the vehicle side view and extending in the vehicle width direction, the peripheral part of said door panel portion comprises a front-side overlapping portion which overlaps with said hinge pillar and said instrument-panel member in the vehicle side view, and said reinforcement portion is provided at said lower-side overlapping portion and said front-side overlapping portion of the peripheral part of the door panel portion;
wherein the reinforcement portion comprises a front-side reinforcement portion disposed along an inner front portion of the door panel portion along the hinge pillar, and a lower-side reinforcement portion disposed along an inner lower portion of the door panel portion which extends along the side sill;
wherein the front-side reinforcement portion overlaps with a rear-side hinge-pillar flange and a hinge-pillar side wall portion of the hinge pillar in the vehicle side view; and
wherein the lower-side reinforcement portion overlaps with an upper-side side-sill flange and a side-sill side wall portion of the side sill in the vehicle side view.

11. The vehicle-body structure of the vehicle of claim 10 , wherein a surface of the front-side reinforcement portion extending along a front-side connection wall portion of the inner fr
