Abstract

Present invention relates to a device for protecting a passenger of a vehicle which includes curtain air bag (CAB) modules disposed at left and right sides of a roof panel inside the vehicle, a driver air bag (DAB) module disposed at a steering wheel inside the vehicle, and an eccentric impact preventing air bag module disposed to be unfolded toward an A-pillar disposed so as to divide a windshield glass disposed at a front side of the vehicle and side doors disposed at lateral sides of the vehicle, thereby effectively protects a driver seat passenger even when an unexpected front collision accident of a vehicle occurs.

Claims

1. A device for protecting a passenger of a vehicle, comprising:

curtain air bag (CAB) modules disposed at left and right sides of a roof panel inside the vehicle;

a driver air bag (DAB) module disposed at a steering wheel inside the vehicle; and

an eccentric impact preventing air bag module disposed to be unfolded toward an A-pillar disposed so as to divide a windshield glass disposed at a front side of the vehicle and side doors disposed at lateral sides of the vehicle,

wherein the eccentric impact preventing air bag module is disposed between the DAB module and the windshield glass,

wherein the eccentric impact preventing air bag module includes;

an air bag cushion filled with gas, and unfolded between the DAB module and the windshield glass; and

an air bag housing in which the air bag cushion is accommodated, and

the air bag housing is fixed to an upper side of a cluster housing, in which an indicator dial of the vehicle is installed, and then is hidden by a dashboard panel covering the cluster housing.

2. The device of claim 1, wherein a cowl cross bar is horizontally elongated and disposed at the front side of the driver seat in the vehicle so as to support the cluster housing and the dashboard panel, and

the eccentric impact preventing air bag module is coupled to a front upper portion of the cluster housing through a first bracket fixed to the cowl cross bar and a second bracket supported by the first bracket.

3. The device of claim 2, wherein one end of the first bracket is fixed to the cowl cross bar, and the other end of the first bracket is extended so as to surround a part of a front portion of the cluster housing to be fixed to the dashboard panel.

4. The device of claim 3, wherein one end of the second bracket is supported by the first bracket, and the other end of the second bracket is bolt-coupled with the air bag housing.

5. The device of claim 4, wherein a tear line torn by unfolding force of the air bag cushion to induce unfolding of the air bag cushion is formed in the dashboard panel.

6. The device of claim 5, wherein the tear line is formed so that the air bag cushion is unfolded in a direction in which the side door adjacent to a driver seat based on the cluster housing is provided.

7. The device of claim 5, wherein the tear line is formed in the dashboard panel in a shape of “

”

opened in a direction opposite to an unfolding direction of the air bag cushion.

8. The device of claim 1, wherein the air bag cushion is unfolded so as to cover a part of the A-pillar when filled with gas.

9. The device of claim 1, wherein the air bag cushion is unfolded so as to cover a lower part of the A-pillar when filled with gas.

10. A device for protecting a passenger of a vehicle, comprising:

curtain air bag (CAB) modules disposed at left and right sides of a roof panel inside the vehicle;

a driver air bag (DAB) module disposed at a steering wheel inside the vehicle; and

an eccentric impact preventing air bag module disposed to be unfolded toward an A-pillar disposed so as to divide a windshield glass disposed at a front side of the vehicle and side doors disposed at lateral sides of the vehicle,

wherein the eccentric impact preventing air bag module is disposed between the DAB module and the windshield glass,

wherein the air bag cushion has;

a front part configuring a front portion so as to be in direct contact with the A-pillar after the unfolding; and

a rear part configuring a rear portion so as to be in direct contact with a head of a driver after the unfolding, and

border portions of the front part and the rear part are sewn and coupled with each other.

11. The device of claim 10, wherein the air bag cushion is formed to have a longest length of the front part larger than a longest length of the rear part.
