Abstract: An 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) inflatable away from the roof adjacent the side structure of the vehicle. A pretensioner (150) connects the curtain (14) to the vehicle (12) and includes rotational element. The inflatable curtain (14) is connected to the rotational element and upon deployment applies a force to the rotational element that causes the rotational element to rotate. The rotational element is configured such that angular momentum causes the rotational element to continue to rotate and thereby tension the inflatable curtain (14).

Abstract: 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).

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 (12) includes a primary housing (20) constructed from sheet metal by stamping, a primary inflation fluid source (100), a secondary housing (70) constructed from sheet metal by stamping, and a secondary inflation fluid source (200).

The secondary housing (70) is disposed within the primary housing (20). The secondary inflation fluid source (200) is located in the secondary housing (70) and is actuatable to affect a secondary flow of inflation fluid to supplement the primary flow of inflation fluid. The secondary housing (70) has a first portion (77) that moves at least partially out of engagement with a second portion (74) of the secondary housing (70) when the secondary inflation fluid source is actuated.

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).

Abstract: A seat belt pretensioner for a belt retractor includes a member that rotates relative to a frame of the belt retractor in response to a vehicle condition to rotate a spool of the belt retractor relative to the frame. A drive device rotates the member in response to the vehicle condition. The drive device applies a first torque to the member during a first stage of rotation of the member and the spool and applies a second torque greater than the first torque during a second stage of rotation of the member and the spool. A flexible drive member rotates the member relative to the frame. The flexible drive member extends around an axis of the member more than 360° after activation of the pretensioner.

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. Tear stitching (200) interconnects portions (220 and 230) of the protection device (14) and is rupturable to permit the interconnected portions to move relative to each other. The tear stitching (200) includes a break point (210) and first and second segments (212) that extend away from the break point. The tear stitching (200) is arranged on the protection device (14) such that tension forces acting to rupture the tear stitching act primarily on the break point (210) so that the tear stitching ruptures first at the break point and then along the first and second segments (212) of the tear stitching.

Abstract: A head restraint (14) for helping to protect an occupant (60) of a vehicle seat (20) includes a base frame (150) connected to the vehicle seat.

Abstract: An apparatus (10b) includes an inflatable vehicle occupant protection device (14b). An inflation fluid source provides inflation fluid for inflating the protection device (14b). A structure (320) for supporting the protection device (14b) includes a vent opening (40b) for venting inflation fluid from the protection device. A vent member (300) is connectable to the structure (320) to block inflation fluid flow through the vent opening (40b). An actuatable device (120b) when actuated breaks the connection between the vent member (80b) and the structure (320) and moves the vent member away from the vent opening (40b) to permit inflation fluid venting. A flexible elongated member (350) has a first end (352) connected to the vent member (300) and a second end (354) connected to the structure (320). The member (350) secures the vent member (300) to the structure (320) after the connection between the vent member and the structure is broken.

Abstract: An apparatus (10) helps to protect a pedestrian from impacts with a vehicle (12) that has a windshield (24) and a hood (32) covering an engine compartment (30). The apparatus (10) includes an air bag (14) that is inflatable away from the engine compartment (30) through a space (342) between the hood (32) and the windshield (24) from a stored condition to a deployed condition positioned adjacent the windshield (24).

Abstract: 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.
