摘要:
A system (10) for controlling a vehicle occupant protection device (52) associated with a vehicle seat (12) includes a weight sensor (40) operative to sense a weight condition of an occupant (26) of the vehicle seat (12) and provide a weight sensor signal. A second sensor (50) is operative to sense a second condition of the occupant (26) and provide a second sensor signal. A controller (34) receives the weight sensor signal and the second sensor signal. The controller (34) analyzes the weight sensor signal and the second sensor signal to determine inconsistencies between the weight sensor signal and the second sensor signal and enables actuation of the occupant protection device (52) if the weight sensor signal and the second sensor signal are inconsistent.

摘要:
A tongue assembly (10) is movable along seat belt webbing (16) and includes a latch plate sub-assembly (74) for engaging a buckle (26). A cinch bar (130) is carried by the latch plate sub-assembly (74) for pivotal movement relative to the latch plate sub-assembly between a disengaged position enabling the seat belt webbing and the latch plate sub-assembly to move relative to one another and an engaged position clamping the seat belt webbing against the latch plate sub-assembly. A method of assembling the tongue assembly (10) comprises the step of inserting a first end (138) of the cinch bar (130) into a first opening (128) in the latch plate sub-assembly (74) by movement of the cinch bar in a first direction (C). A second end (139) of the cinch bar (130) is inserted into a second opening (129) spaced away from the first opening (128) in the latch plate sub-assembly (74) by movement of the cinch bar in a second direction (E) opposite the first direction (C). The first end (138) of the cinch bar (130) is maintained in the first opening (128) while the second end (139) of the cinch bar is inserted in the second opening (129).
摘要:
An apparatus for restraining movement of a vehicle occupant in the event of a side impact to the vehicle includes an air bag module (10) in the vehicle door (12). The air bag module includes front (60) and rear (50) air bags, a source (70) of inflation fluid, and a flow control apparatus (94). The flow control apparatus (94) is actuatable into either a first condition for directing inflation fluid from the source into the front air bag (60) or a second condition for directing inflation fluid into the rear air bag (50). A sensor (26) senses the position of the vehicle occupant and provides a position signal indicative of the vehicle occupant's position. An actuator (80) is responsive to the position signal for actuating the flow control apparatus (94) into either the first or conditions. When the vehicle occupant's seat (20) is disposed forward of a predetermined position in the vehicle, the actuator (80) places the flow control apparatus (94) in the first condition to direct fluid from the inflation fluid source into only the front air bag (60). When the seat (20) is disposed rearward of the predetermined position in the vehicle, the actuator (80) places the flow control apparatus (94) in the second condition to direct fluid flow from the inflation fluid source only into the rear air bag (50).

A vehicle occupant protection apparatus (10) includes an inflatable vehicle occupant protection device (14) which is folded so as to be deployed from a reaction structure (24) in a first direction to restrain movement of a vehicle occupant in a second, opposite direction. The folded protection device (14) has a cross-section with a configuration defined by pleats (110). Each pleat (110) has an open end (112) and a closed end (114) spaced from the open end (112) in a direction substantially parallel to the first and second directions. An inflator (12) is received within one of the pleats (110′) and has inflation fluid outlet openings (124) adjacent to the closed end (114) of the pleat (110′). A retainer ring (56) engages and supports a peripheral edge portion (72) of the folded protection device (14) in an open configuration. The bag retainer ring (56) and the edge portion (72) of the folded protection device (14) are spaced fully from the inflator (12) on opposite sides of the pleated cross-section of the folded protection device (14).
