Abstract

A passive restraint includes inflatable members inflatable to an inflated position. The inflatable members are elongated along a longitudinal axis and spaced from each other in a lateral direction in the inflated position. The passive restraint includes uninflatable panels arranged in an alternating arrangement with the inflatable members. Each panel is elongated in the lateral direction when the inflatable members are inflated and extends from one of the inflatable members to another one of the inflatable members.

Claims

1. A passive restraint comprising:

inflatable members inflatable to an inflated position, the inflatable members being spaced from each other in the inflated position; and

uninflatable panels arranged in an alternating arrangement with the inflatable members and extending from one of the inflatable members to another one of the inflatable members; and

a plurality of inflation pipes extending from a central junction and in fluid communication with the inflatable members.

2. The passive restraint of claim 1, wherein a cross section of at least one of the inflatable members is circular.

3. The passive restraint of claim 1, wherein the panels are aligned in a common plane.

4. The passive restraint of claim 1, wherein the inflatable members in the inflated position and the panels are elongated along a longitudinal axis.

5. The passive restraint of claim 1, wherein the uninflatable panels each include a plurality of segments extending from one of the inflatable members to another one of the inflatable members.

6. The passive restraint of claim 1, wherein one of the inflation pipes has a first port and a second port, the first port positioned to provide fluid to one of the inflatable members, and the second port positioned to provide fluid to another one of the inflatable members.

7. The passive restraint of claim 1, wherein one of the inflation pipes has a plurality of ports, each of the plurality of ports positioned to provide fluid to a separate inflatable member of the inflatable members.

8. The passive restraint of claim 1, wherein one of the plurality of inflation pipes is perpendicular to another of the plurality of inflation pipes.

9. The passive restraint of claim 1, wherein the central junction includes a buffer chamber.

10. The passive restraint of claim 9, further comprising an inflator disposed within the buffer chamber.

11. The passive restraint of claim 1, wherein the panels are formed of fabric.

12. The passive restraint of claim 1, wherein the panels and the inflatable members define a plurality of curtains extending outwardly from a center point.

13. The passive restraint of claim 12, wherein one of the plurality of curtains is perpendicular to another one of the plurality of curtains.

14. A vehicle comprising:

seats spaced from each other;

inflatable members inflatable to an inflated position, the inflatable members in the inflated position being disposed between the seats and spaced from each other; and

uninflatable panels arranged in an alternating arrangement with the inflatable members and extending from one of the inflatable members to another one of the inflatable members;

wherein the panels and the inflatable members define a plurality of curtains extending outwardly from a center point, one of the plurality of curtains extending in a vehicle front-to-rear direction and another one of the plurality of curtains extending in a vehicle side-to-side direction.

15. The vehicle of claim 14, further comprising a floor, the inflatable members supported by the floor.

16. The vehicle of claim 14, further comprising a roof, the inflatable members supported by the roof.

17. The vehicle of claim 14, wherein the panels and the inflatable members define a curtain extending in a vehicle front-to-rear direction.

18. The vehicle of claim 14, further comprising a floor, the seats rotatability supported by the floor.

19. A passive restraint comprising:

inflatable members inflatable to an inflated position, the inflatable members being spaced from each other in the inflated position; and

uninflatable panels arranged in an alternating arrangement with the inflatable members, each uninflatable panel including a plurality of segments extending from one of the inflatable members to another one of the inflatable members.

20. A vehicle comprising:

a floor;

seats spaced from each other;

inflatable members supported by the floor and inflatable to an inflated position, the inflatable members in the inflated position being disposed between the seats and spaced from each other; and

uninflatable panels arranged in an alternating arrangement with the inflatable members and extending from one of the inflatable members to another one of the inflatable members.
