## Abstract

A baffle structure of an open car that may be disposed in a traverse direction at a rear side of a seat of the open car to protect an occupant, may include a lower cross member that may be disposed along a lower floor panel of a vehicle body in the traverse direction and of which a cross-section thereof may be in a shape of pipe, an upper cross member that may be disposed in the traverse direction at a predetermined distance from the lower cross member and of which a cross-section thereof has quadrangle shape, and a column of which a lower end portion thereof may be connected to the lower cross member, an upper end thereof may be connected to the upper cross member, and a cross-section thereof has a quadrangle pipe shape.

## Claims

### Claim 1

A baffle structure of an open car that is disposed in a traverse direction at a rear side of a seat of the open car to protect an occupant, comprising:
a lower cross member that is disposed along a lower floor panel of a vehicle body in the traverse direction and of which a cross-section thereof is in a shape of pipe;
an upper cross member that is disposed in the traverse direction at a predetermined distance from the lower cross member and of which a cross-section thereof has quadrangle shape; and
a column of which a lower end portion thereof is connected to the lower cross member, an upper end thereof is connected to the upper cross member, and a cross-section thereof has a quadrangle pipe shape;
wherein the lower cross member includes:
a first lower cross element that is directly connected to an upper portion of the lower floor panel; and
a second lower cross element that is directly connected to a lower portion of the lower floor panel to form a quadrangle pipe shape with the first lower cross element;
wherein the upper cross member includes:
a first upper cross element of which a lower portion thereof is connected to the column; and
a second upper cross element that is mounted above the first upper cross element and is connected to an upper end portion of the first upper cross element to close the upper end portion of the first upper cross element and that forms the quadrangle shape
a reinforcing member that is disposed inside the first and second upper cross members and is connected to the first upper cross element and the second upper cross element, and where a hollow mounting space is formed therein; and
wherein a mounting hole is formed in the upper cross element to communicate with the hollow mounting space of the reinforcing member so as to install a roll over protect system therethrough.

### Claim 2 (depends on 1)

The baffle structure of the open car of claim 1, wherein the column includes:
side columns that are disposed adjacent to a side panel of the open car and connected to the side panel along a shape of the side panel; and
a central portion column that is disposed between the side columns.

### Claim 3 (depends on 2)

The baffle structure of the open car of claim 2, further comprising a column reinforcement element that is connected to an inner side of the side columns to reinforce rigidity of the side columns.

### Claim 4 (depends on 2)

The baffle structure of the open car of claim 2, wherein the central portion column includes:
a first column element of which a side thereof is opened in the traverse direction of the vehicle body; and
a second column element that is connected to the first column element to cover an opened part of the first column element.

### Claim 5 (depends on 1)

The baffle structure of the open car of claim 1, further comprising a member side element that is connected to both distal ends of the upper cross member, wherein the member side element is connected to a side panel of the vehicle body.

### Claim 6 (depends on 1)

The baffle structure of the open car of claim 1, further comprising a member reinforcing element that is connected along an inner side surface of the upper cross member.

### Claim 7 (depends on 1)

The baffle structure of the open car of claim 1, wherein the cross-sections of the lower cross member, the upper cross member, and the column have a quadrangle shape.
