Abstract

The occupant protection system includes a catching body that is housed in a housing located between a near-by seat and a distant seat for upward deployment and a support body that supports the catching body. The catching body covers the impact side of a distant-side occupant to catch the occupant moving toward the impacted lateral and includes a distal end acting as a free end swingable in a left and right direction. The support body is located on a side of the near-by seat close to the impacted lateral for deployment to support the catching body when the catching body swings toward the impacted lateral after receiving the distant-side occupant.

Claims

1. An occupant protection system mountable on a vehicle having a row of seats arranged along a left and right direction and operable when the vehicle is impacted on a lateral, the system comprising:

a catching body for catching a distant-side occupant seated on a distant seat that is located away from the lateral which has been impacted, the catching body being housed in a housing located between the distant seat and a near-by seat that is located close to the impacted lateral for deployment on a side of the distant seat close to the impacted lateral, the catching body including a fixed end fixed to the housing and a distal end acting as a free end swingable in a left and right direction; and

a support body located on a side of the near-by seat close to the impacted lateral, the support body being configured to support the catching body when the catching body swings toward the impacted lateral upon receiving the distant-side occupant.

2. The occupant protection system of claim 1 wherein the catching body is comprised of an airbag inflatable with inflation gas.

3. The occupant protection system of claim 2 wherein the support body is comprised of a support airbag that is housed in a housing and inflatable with inflation gas for deployment on the side of the near-by seat close to the impacted lateral.

4. The occupant protection system of claim 2 wherein the catching body includes a head restraining region that is capable of restraining a head of the distant-side occupant.

5. The occupant protection system of claim 3 wherein the system is configured such that a deployment direction of the support body from the housing intersects with that of the catching body from the housing as viewed from a lateral of the vehicle.

6. The occupant protection system of claim 1 wherein the housing of the catching body is located at a low position between the near-by seat and the distant seat such that the catching body is deployable upward from the housing.

7. The occupant protection system of claim 6 wherein:

the catching body is comprised of an airbag inflatable with inflation gas; and

the support body is comprised of a support airbag that is housed in a housing and inflatable with inflation gas for deployment on the side of the near-by seat close to the impacted lateral.

8. The occupant protection system of claim 7 wherein the system is configured such that a deployment direction of the support body from the housing intersects with that of the catching body from the housing as viewed from a lateral of the vehicle.

9. The occupant protection system of claim 8 wherein the support body includes two of the support airbags;

a first support airbag and a second support airbag.

10. The occupant protection system of claim 9 wherein:

the first support airbag is configured to deploy downward from the housing and support the catching body at a lower end region thereof;

the second support airbag is configured to deploy forward or rearward from the housing between the first support airbag and the catching body and support the catching body at an upper end region thereof; and

the lower end region of the first support airbag and the upper end region of the second support airbag overlap with each other in an inboard and outboard direction at deployment.
