摘要:
An inflatable vehicle occupant protection device (14) for being inflated between an instrument panel (36) and a seat (22) of the vehicle (12) is provided. The protection device (14) includes a front portion (70) that has a panel (72) presented towards the vehicle seat (22), a rear portion (76) adjacent the instrument panel (36), and top and bottom portions (90, 92) interconnecting the front portion (70) and the rear portion (76) to define an inflatable volume (54). A pocket (100) defines an uninflated volume (102) outside of the inflatable volume (54). The pocket (100) is defined by a single panel (160) of the protection device (14). The panel (100) extends along a centerline (162) and includes an extension (180) of material on each side of the centerline (162). The extensions (180) overly one another and are interconnected along a seam (106) to form the pocket (100).

An inflatable vehicle occupant protection device (14) includes at least one panel (212) of material that defines an inflatable volume (54) of the protection device. The at least one panel (212) has a portion presented toward the vehicle occupant when in an inflated and deployed condition. The protection device (14) includes at least one pleat (296, 316) formed in the at least one panel (212). The at least one pleat (296, 316) defines a cushioned portion (210) for receiving a portion of the occupant. The at least one pleat (296, 316) reduces fabric tension in the cushioned portion (210) to provide the cushioned portion with a degree of softness that is reduced over remaining areas of the protection device (14).

Tear stitching (100) for interconnecting portions (130, 140) of an inflatable vehicle occupant protection device (14) includes first and second end portions (102, 104) having curled configurations and a central portion (110) extending between the end portions. The central portion (110) includes leg portions (112, 114) that converge at an angle and intersect a break point (116). The tear stitching (100) exhibits a comparatively high rupture strength in response to tension forces applied to the interconnected portions (130, 140) that act on the end portions (102, 104) of the tear stitching (100). The tear stitching (100) exhibits a comparatively low rupture strength in response to tension forces applied to the interconnected portions (130, 140) that act on the break point (116) of the tear stitching (100).

An air bag module (30) includes an air bag (14) having a deflated condition and an inflated condition and a structure (34) for supporting the air bag. A first tether (106) has a first end connected to the structure via an actuatable fastener (122) and an opposite second end connected to the air bag (14). A second tether (104) having a first end secured to the first tether (106) by a releasable connection (132) at a location between the first and second ends of the first tether. The second tether has a second end connected to a deployable portion of the air bag (14).
摘要:
An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) comprises an inflatable vehicle occupant protection device (14) inflatable between a vehicle surface (36) and the vehicle occupant. A vent (160) releases inflation fluid from the protection device (14). The vent (160) has an actuated condition and a non-actuated condition. A tether (150) has a first connection with the vent (160) and a second connection with the protection device (14). Tension on the tether (150) actuates the vent (160). The vent (160) is initially in the non-actuated condition upon initial deployment of the protection device (14). Further deployment of the protection device (14) causes the tether (150) to place the vent (160) in the actuated condition. Occupant penetration into the protection device (14) causes the tether (150) to place the vent (160) in the non-actuated condition.
摘要:
An apparatus for helping to protect an occupant (15 or 16) of a vehicle (17) includes an inflatable vehicle occupant protection device (10) and an inflation fluid source. The inflatable vehicle occupant protection device (10) has a stored, deflated position and an inflated position. The inflation fluid source provides inflation fluid to inflate the inflatable vehicle occupant protection device (10). The inflatable vehicle occupant protection device (10) has a first panel portion (501) for, when the inflatable vehicle occupant protection device (10) is inflated, protecting an adult size vehicle occupant (15). The inflatable vehicle occupant protection device (10) has a second panel portion (502) for, when the inflatable vehicle occupant protection device (10) is inflated, defining a downwardly open pocket (520) for receiving a portion of a child size vehicle occupant (16).

An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) includes an inflatable vehicle occupant protection device (14) inflatable from a stored condition to a deployed condition in which the protection device is positioned between an instrument panel (36) of the vehicle and the vehicle occupant. The protection device (14) includes upper portion (142) and a lower portion (144), each of which is at least one of rolled and folded. The upper portion (142) and the lower portion (144) are positioned overlying each other when in the stored condition. A deployment flap (120) includes a sheet of material having a first end portion (130) secured to the vehicle. The deployment flap (120) has a central portion (134) that wraps around the lower portion (144) and a second end portion (132), opposite the first end portion (130), that is tucked under the lower portion while the protection device (14) is in the stored condition.
摘要:
A vehicle occupant protection apparatus (10) includes an inflatable occupant protection device (12) and a support member (40) having a vent opening (50) through which inflation fluid may flow. The apparatus (10) also includes a mechanism (58) for controlling a flow of inflation fluid through the vent opening (50). Inflation fluid pressure within the inflatable occupant protection device (12) tends to move the mechanism (58) for increasing a flow of inflation fluid through the vent opening (50). The mechanism (58) is responsive to inflation of the inflatable occupant protection device (12) beyond a predetermined distance for restricting the flow of inflation fluid through the vent opening (50). The apparatus (10) further includes a locking member (96) for blocking the mechanism (58) from increasing the flow of inflation fluid through the vent opening (50) after the inflatable occupant protection device (12) has inflated beyond the predetermined distance.
摘要:
An apparatus (10) includes an inflatable vehicle occupant protection device (12) and a vent opening (44) for directing flow of inflation fluid away from the protection device. A vent member (46) is movable between an open condition enabling flow of inflation fluid through the vent opening and a closed condition at least partially blocking flow of inflation fluid through the vent opening. A tether (50), when tensioned, moves the vent member (46) from the open condition to the closed condition. A latch (48) has a latched condition for maintaining the vent member (46) in the closed condition and an unlatched condition for enabling the vent member to move away from the closed condition. A controller (102) is operative to actuate the latch (48). selectively to the latched condition and the unlatched condition based on at least one sensed occupant condition.

A vehicle occupant protection apparatus (10) comprises a seat belt system (50) having a buckled condition and an unbuckled condition, and a sensor (56) for determining the buckled condition of the seat belt system. An inflatable occupant protection device (12) has a deflated condition and an inflated condition. An inflator (32) is actuatable to provide inflation fluid to inflate the inflatable device (12). The protection apparatus (10) includes an electrically energizable mechanism (44) for venting inflation fluid from the protection apparatus (10). Electric circuitry (40) is responsive to a determination of the buckled condition of the seat belt system (50) and the inflated condition of the inflatable device (12), for actuating the electrically energizable mechanism (44) to vent inflation fluid.
