Abstract: An occupant protection apparatus comprises an inflatable airbag with a panel, the panel including a first vent opening that permits inflation fluid to escape out of the airbag; and a valve sheet including a second vent opening movable relative to the first vent opening, the valve sheet having opposite ends that are each fixed to a surface of the airbag. One end of the valve sheet moves with the panel during inflation of the airbag to move the second vent opening relative to the first vent opening. The apparatus also includes a valve guide to guide movement of the valve sheet relative to the panel, the valve sheet is capable of sliding between the valve guide and the panel. Both ends of the valve sheet remain fixed to the panel during and after inflation of the airbag.

Abstract: A method of folding an airbag includes pre-folding an airbag in a generally geometric pattern and crush folding the airbag. The airbag is positioned flat on a first side with a first lobe lying over a second lobe. The lower corners of the lobes are tucked internally into their respective lobes or sides. The airbag is then folded twice to form a general Z shape along the side of the airbag. The airbag is then crush folded.

Abstract: An airbag assembly includes an airbag and a system provided in contact with at least a portion of the airbag that includes a first member and a second member. The second member at least partially overlaps the first member and is held in contact during initial deployment of the airbag with the first member by a frictional force between the first member and the second member. The system is configured to cause the airbag to inflate laterally with respect to a vehicle occupant until the frictional force is overcome by inflation of the airbag.

Abstract: A load-limiting device has a mechanical structure designed to dissipate forces applied by a vehicle occupant to a safety belt during a crash. The load limiting device comprises a housing and a deformable member, at least one of which is configured for connection to a vehicle safety belt and the other of which is configured for connection to a structural part of a vehicle. The housing and the deformable member are moveable relative to each other when force is applied to the one of those members. The housing supports a hardened member formed of a material which is harder than the deformable member and which is positioned to engage and deform the deformable member as the deformable member is being moved relative to the housing.

Abstract: An airbag device includes an airbag formed with at least one fabric panel and an inflator. The fabric panel includes at least one loop along a perimeter of the fabric panel. The inflator is a dual stage inflator configured to generate inflation gas during a first inflation stage and a second inflation stage to inflate the airbag. The airbag also includes a tether configured to help control the shape of the airbag when the airbag is inflating, the tether being positioned through the opening or loop when the airbag is in an uninflated state. The tether is severed by heat and/or pressure from inflation gases during the second stage inflation.

Abstract: First and second air bag cushion portions are joined to form a bi-lobular air bag cushion with an opening adapted to receive inflation gas from an air bag inflator. A first inner panel forms first and second chambers in the first cushion portion and provide for fluid communication therebetween proximate to a distal portion thereof. A second inner panel forms third and fourth chambers in the second cushion portion and provide for fluid communication therebetween proximate to a distal portion thereof. Relatively inboard first and third chambers are in fluid communication with one another. The second and fourth chambers are in fluid communication with the opening. In another embodiment, first and second distribution tubes provide for fluid communication between the opening and relatively distal portions of the first and second cushion portions. The inner panels and the distribution tubes provide for lateral inflation of the bi-lobular air bag.

Abstract: First and second tear seams separated by a central portion of a panel of an air bag module cover define opposing first and second lateral edges of an air bag door, and are adapted so as to provide for a first region of the first central portion. Upon actuation of the associated air bag inflator, the tear seams fracture allowing the air bag to first deploy laterally, after which the first region of the panel is fractured responsive to relatively higher stresses therein, thereby opening the air bag door. In one embodiment, the tear seams extend along portions of the upper and lower boundaries of the air bag door, and a third tear seam is provided between the portions of the first and second tear seams on one of the upper and lower boundaries, wherein the third tear seam is relatively stronger than the first and second tear seams.

Abstract: Disclosed is a safety restraint design controller for controlling the design of a safety restraint system so that a predetermined desired level of an occupant's response is produced. The controller has a database for storing a occupant restraint factor response model. The model interrelates at least one predetermined restraint factor with the occupant response; the restraint factors having a level which is indicative of setting values for controlling the safety restraint design. A database engine connected to the database determines a level for the occupant response based upon the model and upon a first level of the restraint factors.

Abstract: An energy management device has a plurality of electromagnets positioned between a shaft and a seatbelt spool. When energized, the electromagnets move radially outwardly to engage the inside surface of a hub of the seatbelt spool. By adjusting the amount of current supplied to the electromagnets, the amount of friction, and thus the amount of energy dissipated, can be controlled. A D-ring can be supported on the cable which goes to a spool so that during a crash the ring moves forward as cable is pulled out of the spool which in turn is braked by the energy management device.

Abstract: A rotatable spool has seat belt webbing wound around the spool. A motor, when actuated, rotates the spool in the belt withdrawal direction. A spring has a biasing force which rotates the spool to wind the belt webbing onto the spool. A worm gear mechanism is located between the motor and the spool and is selectively drivingly connectable with the spool. When drivingly connected with the spool, the worm gear mechanism prevents the biasing force of the spring from winding the belt webbing onto the spool. A clutch, when engaged, connects the spool and the worm gear mechanism. The clutch is disengaged and the motor is deactuated when a belt tension signal is below a lower predetermined threshold value. The clutch is engaged and the motor is actuated when the belt tension signal is above an upper predetermined threshold value which is greater than the lower predetermined threshold value.
