Abstract

A containment impact protection system having a deployable barrier panel substantially covers the side windows of the vehicle when the system is deployed. A longitudinally disposed inflatable tube member is attached to the barrier panel at a location approximately halfway between the top and bottom of the windows. A tensioning device responsive to the inflation of the inflatable tube member produces a force deploying the barrier panel from a stored state to a deployed state. A longitudinal inflatable cushion is provided between the inflatable tube member and the bottom of the barrier panel.

Claims

1. A containment impact protection system for use in an automotive vehicle comprising:

a barrier panel attachable to a roof rail of the vehicle and having an inflatable portion, the barrier panel deployable from a stored state to a deployed state, wherein the barrier panel substantially covers at least one side window of the vehicle when in the deployed state;

the inflatable portion of the barrier panel including an inflatable cushion without a tensioning device provided longitudinally along a bottom portion of the barrier panel;

an inflatable tube structure having an inflatable tube member and a tensioning device connectable to structural members of the vehicle on opposite sides of the at least one side window, the tensioning device producing a longitudinal tension in response to the inflation a of the inflatable tube member operative to deploy the barrier panel;

at least one sling attached to the barrier panel, the at least one sling supporting the inflatable tube structure above the inflatable cushion substantially parallel to the bottom of the barrier panel; and

an inflator for producing a gas rapidly inflating the inflatable cushion and the inflatable tube member in response to a transverse acceleration above a predetermined value.

2. The containment impact protection system of claim 1 wherein the vehicle has at least two side windows, the barrier panel in the deployed state substantially covers the at least two side windows and the tensioning device is connected to structural members of the vehicle on opposite sides of the at least two windows.

3. The containment impact protection system of claim 2 wherein the inflatable cushion is formed as an integral portion of the barrier panel.

4. The containment impact protection system of claim 2 wherein the at least one sling comprises two longitudinally spaced slings attached to the barrier panel.

5. The Containment impact protection system of claim 2 wherein the at least one sung is a sleeve attached to the barrier panel, the sleeve having a length substantially equal to the length of the inflatable tube member.

6. The containment impact protection system of claim 1 wherein the at least one inflator comprises a first inflator for inflating the inflatable cushion and a second inflator for inflating the inflatable tube structure.

7. A containment impact protection System for use in a vehicle having at least two side windows on each side of the vehicle, the protection system comprising:

a barrier panel attachable to structural members of the vehicle above the two windows and having an inflatable portion, the bailer panel having a stored state and a deployed state, in the deployed state the barrier panel substantially coven the at least two windows;

an inflatable tube member slidably attached to the barrier panel at a location approximately halfway between the top and bottom of the windows;

a tensioning device connectable to structural members of the vehicle on opposite sides of the two windows, the tensioning device responsive to the inflation of the inflatable tube member to produce a tensioning force deploying the bailer panel; and

said inflatable portion of the barrier panel including an inflatable cushion without a tensioning device provided longitudinally along the bottom portion of the barrier panel, the inflatable cushion covering the two windows in the region between the inflatable tube structure to the bottom of the barrier panel.

8. The protection system of claim 7 further including means for rapidly inflating the inflatable tube member and the inflatable cushion in response to an impact to the vehicle having a force greater than a predetermined force.

9. The containment impact protection system of claim 8 wherein the inflatable portion of the barrier panel is further including a gas passageway extending from the top of the barrier panel to the inflatable cushion, the means for rapidly inflating the inflatable tube member and the inflatable cushion being connected to the gas passageway to inflate the inflatable cushion.

10. The containment impact protection system of claim 8 having a first inflator providing inflation gas to the inflatable cushion and a second inflator providing inflation gas to the inflatable tube member.

11. The containment impact protection system of claim 7 wherein the inflatable cushion is formed as an integral portion of the barrier panel.

12. The containment impact protection system of claim 7 wherein the barrier panel has a pair of spatially separate slings slidably receiving the inflatable tube member and the tensioning device.

13. The containment impact protection system of claim 7 wherein the barrier panel has a sleeve slidably receiving the inflatable tube member and the tensioning device.

14. A containment impact protection system for USC in an automotive vehicle comprising:

a barrier panel attachable to a roof rail of the vehicle and having an inflatable portion, the barrier panel deployable from a stored state to a deployed state, wherein the barrier panel substantially covers at least one side window of the vehicle when in the deployed state;

the inflatable portion of the barrier panel including an inflatable cushion without a tensioning device provided longitudinally along a bottom portion of the barrier panel;

an inflatable tube structure having an inflatable tube member and a tensioning device connectable to structural members of the vehicle, the tensioning device producing a longitudinal tension in response to the inflation of the inflatable tube member operative to deploy the barrier panel; and

an inflator for producing a gas rapidly inflating the inflatable cushion and the inflatable tube member in response to a transverse acceleration above a predetermined value;

said barrier panel including an outer panel and an inboard panel, one of said outer and inboard panels being configured to the shape of said inflatable cushion and sufficiently sealingly attached to the other panel to form the inflatable cushion so that the inflating gas from said inflator remains in the inflatable cushion for an extended predetermined time.

15. The containment impact protection system of claim 14 including a gas feed passageway in communication with said inflatable cushion and wherein said one of said outer and inboard panels is configured to the shape of said gas feed passageway.

16. A containment impact protection system for use in an automotive

a barrier panel attachable to a roof rail of the vehicle and having an inflatable portion, the barrier panel deployable from a stored state to a deployed state, wherein the barrier panel substantially covers at least one side window of the vehicle when in the deployed state;

the inflatable portion of the barrier portion including an inflatable cushion longitudinally along a bottom portion of the barrier panel;

an inflatable structure having an inflatable tube member and a tensioning device response to the inflation of the inflatable tube member operative to deploy the barrier connectable to structural members of the vehicle, the tensioning device producing a longitudinal panel; and

an inflator for producing a gas rapidly inflating the inflatable cushion and the inflatable tube member in response to a transverse acceleration above a predetermined value;

said barrier panel including an outer panel and an inboard panel, one of said outer and inboard panels being configured to the shape of said inflatable cushion and sufficiently sealingly attached to the other panel to form the inflatable cushion so that the inflating gas from said inflator remains in the inflatable cushion for an extended predetermined time;

said containment impact protection system including a gas feed passageway in communication with said inflatable cushion and wherein said one of said outer and inboard panels is configured to the shape of said gas feed passageway.
