Airbag cushion with cinch tube for reduced out-of-position effects
First Claim
Patent Images
1. An airbag cushion, comprising:
- an inflatable airbag;
a cinch tube disposed on the inflatable airbag and circumventing an aperture disposed in the airbag; and
a cinch cord coupled to the cinch tube and extending around a majority of the perimeter of the cinch tube, the cinch cord further coupled to a surface of the airbag such that upon inflatable airbag deployment with obstruction, the cinch cord does not fully extend and the cinch tube remains open, and upon inflatable airbag deployment without obstruction, the cinch cord extends and at least partially closes the cinch tube.

Abstract
An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a tube that may be restricted to prevent gas venting. A cord is coupled to the tube and to a surface of the cushion. Upon airbag deployment, the cord extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the cord tightens the tube and restricts gas venting. If the cushion encounters an obstruction, the cord remains lax and the tube is able to vent gas.

11. An airbag cushion, comprising:
-
an inflatable airbag;
a first cinch tube disposed on the inflatable airbag and circumventing a first aperture disposed in the airbag;
a second cinch tube disposed on the inflatable airbag and circumventing a second aperture disposed in the airbag;
a cinch cord coupled to the first and second cinch tubes and extending around a majority of the perimeter of the cinch tubes; and
a cinch loop coupled to a surface of the airbag, the cinch cord passing through the cinch loop such that upon inflatable airbag deployment with obstruction, the cinch cord does not fully extend and the cinch tubes remain open, and upon inflatable airbag deployment without obstruction, the cinch cord extends and at least partially closes the cinch tubes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An airbag cushion, comprising:
-
an inflatable airbag;
means for venting gas out of the airbag and circumventing an aperture disposed in the airbag; and
means for restricting gas venting by cinching the venting means to reduce the circumference of the venting means upon inflatable airbag deployment without obstruction and enabling the venting means to remain open upon inflatable airbag deployment with obstruction.
