Abstract

A side safety barrier device to protect occupants of a vehicle includes a crash sensor to generate at least one actuator signal when a crash having predetermined properties is sensed. A safety barrier is normally stored in the headliner of the vehicle in a first or stored position and selectively deployable to a second or deployed position by the safety barrier deployment assembly when signaled by the crash sensor to separate or isolate the side of the vehicle on which the side safety device is disposed from the interior of the vehicle.

Claims

1. A side safety barrier device to protect an occupant of a vehicle during a crash wherein the vehicle has a vehicle side wall having a window area formed in part between a first pillar and a roof rail, said side safety barrier device comprising:

a means for detecting and signaling the occurrence of a crash with predetermined properties;

a safety barrier coupled to the roof rail and selectively movable between a normally stored configuration and a deployed position, said safety barrier being stored in a headliner near the roof rail with perforations extending through said headliner such that the headliner breaks open to release the safety barrier when the side safety barrier device is deployed;

a barrier deployment assembly attached to the first pillar to move said safety barrier from said normally stored position to said deployed position to separate the side of the vehicle on which the side safety barrier device is disposed from the interior of the vehicle when a crash has been detected and signaled, said barrier deployment assembly comprising a barrier positioning element that is a member coupled to said safety barrier by a flexible positioning element having a centrally disposed channel formed therethrough to operatively receive the guide element and means coupled to said means for detecting and signaling to move said barrier positioning element from said first position to said second position when a side impact has been detected and signaled coupled to said safety barrier and slidably mounted on a positioning guide means that is a guide element with a tapered surface formed on the front portion thereof mounted to the first pillar for guiding said barrier positioning element from a first position to a second position to move said safety barrier from said normally stored position to said deployed position; and

,

a safety barrier securing means that is a ring affixed to the first pillar by a mounting member extending outwardly from said ring for securing a portion of the safety barrier in said second position, the inside diameter of said ring being be slightly less than the outside diameter of said member such that said tapered surface will direct or guide the barrier positioning element through the ring under the force of the propellant.

2. The side safety barrier device of claim 1, wherein said safety barrier comprises a flexible shield.

3. The side safety barrier device of claim 2, wherein said safety barrier further comprises a cushion.

4. The side safety barrier device of claim 3, wherein said cushion is an inflatable bladder operatively coupled to a means to inflate said inflatable bladder, and wherein said means to inflate is operatively coupled to said means to detect and signal a side impact.

5. The side safety barrier device of claim 4, wherein said cushion comprises a center section that when said side safety barrier device is deployed is positioned between the occupant and the central portion of the window.

6. The side safety barrier device of claim 5, wherein said center section is inclined upwardly from the front to the back of the vehicle.

7. The side safety barrier device of claim 5, wherein said cushion further comprises a generally diagonally disposed section that when said side safety barrier device is deployed is positioned between the occupant and the first pillar.

8. The side safety barrier device of claim 5, wherein the vehicle side wall further includes a central pillar and wherein said cushion further comprises a generally vertically disposed section that when said side safety barrier device is deployed is positioned between the passenger and the central pillar.

9. The side safety barrier device of claim 1, wherein the means to move said barrier positioning element comprises a chamber formed in the rear position thereof and a propellant stored within said chamber.

10. The side safety barrier device of claim 1, wherein said side safety barrier device further comprises a safety barrier securing means for securing a portion of the safety barrier in said second position.

11. The side safety barrier device of claim 1 wherein said barrier positioning element comprises a malleable metal.

12. The side safety barrier device of claim 1 wherein said barrier positioning element comprises hard rubber.
