Abstract: 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.

Abstract: An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) includes an inflatable vehicle occupant protection device (14) comprising a panel (114) that at least partially defines an inflatable volume (54) of the protection device. A vent (100) includes a sidewall that extends through the panel (114) and defines a passage (134) for venting inflation fluid from the inflatable volume (54). The vent (100) includes a first portion (102) extendable inside the inflatable volume (54) and an opposite second portion (104) extendable outside the inflatable volume. The vent (100) has an open condition in which the first portion (102) is maintained inside the inflatable volume (54) and thereby permits venting of inflation fluid through the passage (134), and a closed condition in which the first portion (102) is inverted and positioned in the second portion (104) thereby blocking inflation fluid from venting through the passage (134).

Abstract: 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) includes a vent opening with a flow area that can be adjusted to throttle inflation fluid flow through the vent. 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) throttles the vent (160). The second connection of the tether is positioned on the protection device (14) such that deployment of the protection device throttles the vent (160) toward an actuated condition, and occupant (20) penetration into the protection device throttles the vent toward a non-actuated condition.

The central recess (200) and the first and second lobes (202 and 204) are defined at least partially by an elongated center panel (210) of the protection device (14). The center panel (210) includes first and second longitudinal edges (250 and 252) that are spaced apart from each other and that extend along the length of opposite edge portions of the center panel. The center panel (210) also includes first and second end portions (260 and 280) that are spaced apart and that are positioned opposite each other along the length of the center panel.

Abstract: An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) includes an inflatable vehicle occupant protection device (14) having a deflated condition and an inflated condition. The protection device (14) includes a panel (74) having a portion presented toward the occupant (20) when the protection device is in the inflated condition. A tether (60) has a first connection (78) to a first portion (80) of the panel (74) and a second connection (72) to a second portion (76) of the panel. The tether (60) is operative to limit deployment of the second portion (76) of the panel (74) in response to unrestricted deployment of the first portion (80) of the panel. The tether (60) is also operative to permit further deployment of the second portion (76) of the panel (74) in response to occupant penetration into the first portion (80) of the panel.
