Title:
AIR BAG IN AIR BAG UNIT
Document Type and Number:
WIPO Patent Application WO/1991/018763
Kind Code:
A1
Abstract:
An air bag of an air bag unit provided with an opening (9) through which an inflator actuated in an emergency penetrates and with exhaust ports (8) for discharging the internal pressure of the air bag around this opening (9), wherein the ports (8) are formed at those portions where warps (11) and wefts (10) of a woven fabric cross obliquely with respect to the line connecting the center of each of these ports (8) to the center of the opening (9). Accordingly, the stress occurring around the exhaust port (8) is supported by both the warps (11) and wefts (10) of the woven fabric of the air bag (3) and breakage around the periphery of the exhaust port (8) is less likely to occur than in the conventional air bags wherein this stress is supported by the warps or wefts alone. For this reason, breakage of the air bag (3) around the exhaust port (8) can be prevented without fail and the reliability of the air bag (3) can be improved drastically.
