Title: Airbag with non-circular vent hole
Inventor: NELSEN JAMES M
IPC: B60R21/239
Filed: 1997-06-25
Abstract: PURPOSE: An airbag with non circular vent holes which is both structurally efficient and provides a reasonable flow path is provided. CONSTITUTION: A flexible pressure vessel comprises an inflatable chamber having at least one wall and a non-circular vent hole in the wall. And the vent is a geometric discontinuity in the fabric membrane and presents a stress concentration as the airbag is pressurized.
