Center side airbag
The present invention relates to a center side airbag capable of supporting the airbag cushion without relying on the center console to protect the occupants. The present invention introduces a center side airbag including an airbag cushion arranged between a first seat and a second seat and configured to deploy upward and downward, a lower region configured to deploy in a shape protruding toward the second seat from a lower portion of the airbag cushion, and an upper region configured to deploy in a shape protruding toward an occupant seated on the first seat from an upper portion of the airbag cushion.
1. An airbag configured, when deployed, to be positioned between first and second seats disposed side by side in a vehicle, the airbag having an airbag cushion comprising:
an intermediate region configured to expand between the first and second seats when the airbag cushion is inflated and deployed;
a lower region connected to a lower end portion of the intermediate region and configured to protrude from the lower end portion of the intermediate region toward the second seat when the airbag cushion is inflated and deployed; and
an upper region connected to an upper end portion of the intermediate region and configured, when deployed, to protrude from the upper end portion of the intermediate region toward an occupant seated on the first seat when the airbag cushion is inflated and deployed,
wherein, when the airbag cushion is inflated and deployed between the first and second seats, the intermediate region has a first length in a vertical direction of the vehicle that is greater than a second length of the lower region in the vertical direction of the vehicle and a third length of the upper region in the vertical direction of the vehicle.
2. The airbag of claim 1 , wherein the lower region is configured to be bent to protrude toward the second seat when the airbag cushion is inflated and deployed.
3. The airbag of claim 2 , further comprising a connecting member connected to and extending between the lower region and the intermediate region and configured to create a tension causing the lower region to be bent.
4. The airbag of claim 3 , wherein:
the intermediate region includes an inactive zone configured not to be filled with gas when the airbag cushion is inflated, and
the connecting member is connected to the inactive zone.
5. The airbag of claim 3 , wherein the connecting member comprises upper and lower inactive zones respectively extending from the upper and lower regions.
6. The airbag of claim 1 , wherein the upper region is configured to be bent to protrude toward the first seat when the airbag cushion is inflated and deployed.
7. The airbag of claim 6 , further comprising a connecting member extending between the upper region and the intermediate region and configured to create a tension causing the upper region to be bent.
8. The airbag of claim 1 , wherein the lower region is configured to deploy before the upper region deploys when the airbag cushion is inflated and deployed.
