摘要:
A vehicle (10) has an opening (14) for ingress to and egress from a passenger compartment (12) in the vehicle. A door (16) has a closed position blocking the opening (14) and an open position enabling ingress and egress through the opening. A structure (22, 60) assists in maintaining the door (16) in the closed position. An actuatable device (30, 74), when actuated, renders the structure unable to assist in maintaining the door in the closed position.

An apparatus (10) includes a member (14) that has a first slot (30) extending through the member within the periphery (32) of the member. The first slot (30) has opposed spaced surfaces (34) that define a gap (40) that has a width measured from one of the opposed surfaces to the other of the opposed surfaces. The member (14) includes first and second portions (42 and 44) positioned on opposite sides of the first slot (30). The apparatus (10) also includes a sensor (16) that has a first end (100) connected to the first portion (42) on one side of the first slot (30) and an opposite second end (102) connected to the second portion (44) on an opposite side of the first slot such that the sensor extends across the first slot. The apparatus (10) further includes a fastener (20) for fixedly connecting the second portion (44) to inhibit movement of the second portion of the member relative to the first portion (42). The first portion (42) moves relative to the second portion (44) when a force is applied to the first portion, which causes the width of the gap to change. The sensor (16) provides a signal in response to the change in the gap width.
摘要:
An apparatus (10) for helping to protect a vehicle occupant includes an actuatable vehicle occupant protection device (12), and a microelectromechanical (MEMS) device (20) energizable to cause actuation of the protection device. In one embodiment, the MEMS device (20) is an energizable fluid source for emitting a primary fluid for actuating an inflatable protection device (12). The apparatus (10) may comprise a plurality of MEMS devices (20) individually actuatable to control inflation of the protection device.

A pretensioner (50) tensions vehicle seat belt webbing (18). The pretensioner (50) has a member (52) movable by an actuating fluid to tension the seat belt webbing (18). The pretensioner (50) further has at least one microelectromechanical system (MEMS) device (120) energizable to supply actuating fluid to move the member (52).
摘要:
Apparatus (10) for helping to protect an occupant of a vehicle (12) comprises an inflatable vehicle occupant protection device (14) inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle and a vehicle occupant. The protection device (14), when inflated, has an upper edge (50) positioned adjacent the roof (18) and a lower edge (52) spaced from the roof. The protection device (14) also includes a guide (72, 74) and a flexible elongated member (70, 80) that extends through the guide and is slidable through the guide when the protection device is inflated. The member (70, 80) has two leg portions (110, 112) extending from the side structure (16) of the vehicle (12) to the protection device (14) when the protection device is inflated.
摘要:
An apparatus for inflating a vehicle occupant restraint includes containing means for receiving gases to provide a combustible mixture of the gases. An igniter is activated to effect ignition of the mixture of gases in response to sudden vehicle deceleration. A directing means directs a flow of gas from containing means into the inflatable occupant restraint. In the preferred embodiment the gases are an inert gas, a fuel gas, and an oxidizer gas. Also, a lean mixture of a fuel gas and oxidizer gas could be used. An improved igniter transmits energy through an imperforate portion of a wall of the containing means to ignite a charge in the containing means. The igniter may include an elongate core disposed in a frangible sheath which is shattered as the core is burned.

An apparatus (10) for inflating an inflatable device (8) includes a container (12) defining a chamber (14) containing gas. The container (12) includes a rupturable wall (24) which is rupturable when the pressure in the container reaches a predetermined level. An igniter (46) spaced from the rupturable wall (24) produces a shock wave in the gas which ruptures the rupturable wall (24) prior to the gas pressure in the container (12) reaching the predetermined level.
摘要:
An apparatus (10a) comprises an inflatable vehicle occupant protection device and a container (16a) which contains inflation fluid. A valve (30a) is located outside the container in an inflation fluid flow path extending from the container to the protection device. An initiator (20a) is actuatable to initiate a flow of the inflation fluid from the container (16a) to the valve (30a) along the flow path. The valve (30a) includes a metering member (70a) and a thermostatic metal element (72a) engaging the metering member to move the metering member in the flow path under the influence of changes in the ambient temperature prior to initiation of the flow. Preferably, the metering member (70a) normally has an initial position defining an initial outlet flow area. The valve (30a) preferably further includes pyrotechnic material (140a) which, when ignited, produces combustion products that develop a thrust that moves the metering member (70a) to a subsequent position defining a subsequent outlet flow area greater than the initial outlet flow area.
摘要:
An inflatable vehicle occupant protection device system (10, 110) for helping to protect a vehicle occupant in a crash event includes a module (12, 112), which may be mounted in a vehicle and includes an inflatable vehicle occupant protection device (24, 124). A mechanism controls flow of inflation fluid from an inflator (26, 126) to the protection device (24, 124). The mechanism also includes a first igniter (30, 130) and a second igniter (32, 132), which provide for inflation fluid flow from the inflator (26, 126) to the inflatable vehicle occupant protection device (24, 124). The system (10, 110) also includes a crash sensor (14, 114) for sensing a vehicle crash event and providing an activation signal. The igniters (30, 130 and 32, 132) are responsive to the crash sensor (14, 114) over a shared signal path (16, 116 and 18, 118) between the module (12, 112) and the crash sensor (14, 114). A delay device (46, 146) delays actuation of the second igniter (32, 132) for a predetermined time period after actuation of the first igniter (30, 130).
摘要:
An air bag module (10) includes a container (12) and an air bag (16) connected with the container. An inflator (14) is also connected with the container (12). Means, such as, mounting flanges (42, 46), support the container (12) on a vehicle portion (18) for movement relative to the vehicle portion in a first direction ("I") opposite the direction of the inflation of the air bag (16) in response to actuation of the inflator (14). Damping means (102) connected between the container (12) and the vehicle portion (18) damps movement of the container in the first direction ("I") relative to the vehicle portion.
