摘要:
An apparatus (10) helps protect an occupant (20) of a vehicle (12). The apparatus (10) includes an inflatable vehicle occupant protection device (14). The protection device (14) includes a first chamber (166) inflatable between a thorax (122) of the occupant (20) and a side structure (16) of the vehicle (12). The protection device (14) also includes a second chamber (162) inflatable between a head (100) of the occupant (20) and the side structure (16) of the vehicle (12). The apparatus (10) further includes an inflation fluid source (22) for inflating the first chamber (166) to a first pressure and for inflating the second chamber (162) to a second pressure that is greater than the first pressure.

Apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) includes an inflatable vehicle occupant protection device (14) that is inflatable into a position between the side structure of the vehicle and a vehicle occupant. An inflation fluid source (24) provides inflation fluid for inflating the protection device (14). The protection device (14), when inflated, has a perimeter (44) and front and rear portions (58 and 60) spaced apart horizontally along the protection device. The protection device (14) includes overlying panels (40 and 42) that define an inflatable volume and at least one connection (80) within the perimeter (44) at which the overlying panels are interconnected. The at least one connection (80) defines inflatable chambers (100) of the protection device (14) that extend between the front and rear portions (58 and 60) in a generally horizontal direction when the protection device is inflated. The front and rear portions (58 and 60) are inflated more rapidly away from the vehicle roof (18) than the chambers (100) are inflated when the protection device (14) is inflated.

Apparatus (10) for helping to protect an occupant of a vehicle (12) includes an inflatable windshield curtain (14). The windshield curtain (14) is inflatable away from a roof (40) of the vehicle to a position between a windshield (50) of the vehicle and a vehicle occupant. The windshield curtain (14) includes an inflatable upper portion (190) and an inflatable lower portion (192). The upper portion (190) is inflatable between the roof (40) and an instrument panel (64) of the vehicle (12) and between the windshield (50) and a vehicle occupant. The lower portion (192) is bifurcated and includes a first chamber (194) inflatable against a surface (222) of the instrument panel (64) presented generally toward the vehicle occupant. The lower portion (192) also includes a second chamber (196) inflatable against the windshield (50) and a surface (220) of the instrument panel (64) adjacent the windshield.
摘要:
Apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) comprises an inflatable vehicle occupant protection device (14). The inflatable device (14) is inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle (12) and a vehicle occupant (74). The inflatable device (14) includes overlying panels (40 and 42) that are interconnected along at least a portion of a perimeter (48) of the inflatable device to define an inflatable volume of the inflatable device. The inflatable device (14) when inflated has a predetermined thickness measured between overlying points on the overlying panels (40 and 42) at a location where the head of an occupant may contact the inflatable device. An inflation fluid source (24) provides inflation fluid to the inflatable device (14) for inflating the inflatable device. The inflation fluid in the inflatable device (14) is pressurized to a predetermined pressure when the inflatable device is inflated. The predetermined pressure is determined as a function of the predetermined thickness of the inflatable device (14).
摘要:
Apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) includes an inflatable curtain (14) that has an inflatable volume (34). A first fill tube (42) has a portion positioned in a first portion (50) of the inflatable volume (34). A second fill tube (44) has a portion positioned in a second portion (52) of the inflatable volume (34). An inflation fluid distribution manifold (70) is connectable with an inflator (40). The manifold (70) includes a first flow orifice (196) that directs inflation fluid to flow into the first fill tube (42) at a first flow rate. The manifold (70) includes a second flow orifice (198) that directs inflation to fluid flow into the second fill tube (44) at a second flow rate different than the first flow rate.
