Abstract

A body structure for a vehicle includes an A-pillar and a side sill, wherein the A-pillar includes a vertical front pillar; a front roof pillar extending from an upper end of the vertical front pillar toward an upper rear side thereof; a first reinforcing plate provided in the vertical front pillar and extending in the same direction with the vertical front pillar; and a second reinforcing plate provided in the front roof pillar extending in the same direction with the front roof pillar. The side sill is connected to a lower end of the vertical front pillar and extending along a horizontal direction. The first reinforcing plate is formed to cover a front door hinge mounting portion in the A-pillar and a connection portion of the vertical front pillar and the side sill. An uncoupled portion is formed between the second reinforcing plate and the first reinforcing plate.

First claim

What is claimed is:

1. A body structure for a vehicle, comprising:
an A-pillar and a side sill,
wherein the A-pillar includes:
a vertical front pillar;
a front roof pillar extending from an upper end of the vertical front pillar toward an upper rear side thereof;
a first reinforcing plate provided in the vertical front pillar, the first reinforcing plate extending in the same direction with the extending direction of the vertical front pillar; and
a second reinforcing plate provided in the front roof pillar, the second reinforcing plate extending in the same direction with the extending direction of the front roof pillar,

the side sill is connected to a lower end of the vertical front pillar and the side sill extending along a horizontal direction,
the first reinforcing plate is formed to cover both of a front door hinge mounting portion in the A-pillar and a connection portion of the vertical front pillar and the side sill, and
an uncoupled portion is formed between a lower end of the second reinforcing plate and an upper end of the first reinforcing plate.

2. The body structure for a vehicle according to claim 1 ,
wherein the vertical front pillar includes a lower outer plate and a lower inner plate disposed to face each other,
the front roof pillar includes an upper outer plate and a lower outer plate disposed to face each other,
an upper end of the lower outer plate is joined with a lower end of the upper outer plate, and a first connection gap is formed in a joined portion of the lower outer plate and the upper outer plate,
an upper end of the lower inner plate is joined with a lower end of the upper inner plate, and a second connection gap is formed in a joined portion of the lower inner plate and the upper inner plate, and
a horizontal height of the uncoupled portion, a horizontal height of the first connection gap, and a horizontal height of the second connection gap are different from each other.

3. The body structure for a vehicle according to claim 2 , wherein the horizontal height of the uncoupled portion is higher than the horizontal height of the first connection gap and the horizontal height of the second connection gap.

4. The body structure for a vehicle according to claim 1 , further comprises a front rail extending in a horizontal direction and connected to the A-pillar,
wherein the horizontal height of the uncoupled portion is different from a horizontal height of the front rail.

5. The body structure for a vehicle according to claim 4 ,
wherein the vertical front pillar includes a lower outer plate and a lower inner plate disposed to face each other,
