摘要:
An apparatus for controlling an actuatable restraint system (20) in response to a sensed position of an occupant (36) in an occupant compartment of a vehicle includes a variable capacitor (60) mounted relative to a known reference location (30) within the vehicle. The variable capacitor (60) is adapted so that its capacitance value is functionally related to the occupant's position relative to the reference location (30). A controller (50) is coupled to a capacitance sensing circuit (80) for controlling the actuatable restraint (22) in response to the sensed occupant position relative to the reference location.

An apparatus (20) for use in simulating vehicle side impacts includes a target sled (24) and a bullet sled (26). A door structure (46) is disposed on the target sled (24). A seat (44) is disposed on the target sled (24) adjacent to an inner side (58) of the door structure (46) to support a test dummy (22) in a desired relationship with the door structure. A safety apparatus (178) with an air bag (182) is supported adjacent to the door structure (46) and the seat (44). Upon impacting of the bullet sled (26) against an outer side (60) of the door structure (46), the air bag (182) is inflated and the door structure is moved relative to the seat (44). As this occurs, a connector assembly (238) interconnects the door structure (46) and the bullet sled. Continued movement of the bullet sled (26) and door structure (46) relative to the target sled (24) moves the seat (44) along tracks (154 and 156) disposed on the target sled (24). After the bullet sled (26) has moved the door structure (46) to a predetermined position relative to the target sled (24), the bullet sled engages the target sled and moves the target sled and the deceleration of the bullet sled and target sled are controlled.

A door assembly (10) for an inflatable vehicle occupant restraint module (14) includes two doors (80, 100) which are pivotally mounted for movement between a closed position and an open position. The doors (80, 100) cover an opening (28) through which an inflatable air bag (22) deploys. Each door (80, 100) has at least one finger portion (120, 140, 152, 154) which overlaps the other door when the doors are in the closed position. The overlapping finger portions (120, 140, 152, 154) prevent inward pivoting movement of the doors (80, 100). A retainer assembly (200) holds the doors (80, 100) in the closed position and releases the doors to pivot outward upon inflation of the air bag (22). The retainer assembly (200) includes a frangible member (224) which ruptures.
摘要:
An inflatable vehicle occupant restraint system comprises a source of inflation fluid (20) and an air bag reaction canister (24) having a vent opening (16) through which inflation fluid from the source of inflation fluid (20) may be vented away from the air bag canister (24). An air bag (12) is located in the air bag reaction canister (24) and is inflatable by inflation fluid from the source of inflation fluid (20). A valve member (30) is located on the air bag reaction canister (24). The valve member (30) is movable relative to the vent opening (16) in response to ambient temperature variations in the vicinity of the source of inflation fluid (20) to control venting of inflation fluid from the source of inflation fluid (20) through the vent opening (16). Inflation of the air bag (12) is thereby controlled in response to ambient temperature variations in the vicinity of the source of inflation fluid (20).
摘要:
A length of shoulder belt webbing is extensible around the torso of a vehicle occupant to restrain forward movement of the vehicle occupant in the vehicle. A webbing guide guides the belt webbing around the body of the vehicle occupant. In response to vehicle deceleration at a rate above a predetermined rate, a pyrotechnic charge directs gas under pressure into an expansible chamber to move the webbing guide upward on the vehicle to tension belt webbing extending through the webbing guide. A gas outlet enables controlled flow of gas out of the expansible chamber to allow controlled downward movement of the webbing guide under tension in the belt webbing resulting from forward movement of the vehicle occupant subsequent to upward movement of the webbing guide. The webbing guide may be height adjustable by the vehicle occupant. The pyrotechnic charge may be connected with the webbing guide for movement with the webbing guide.

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. A cushion carrier (350) is supported on the base frame (150) by a track assembly (440) that facilitates movement of the cushion carrier (350) relative to the base frame (150) along a deployment axis (18) from a non-deployed condition to a deployed condition. The track assembly (440) includes a fixed track member (182) that forms a portion of the base frame (150). The fixed track member (182) includes spaced axially extending beam portions (190) with opposing surfaces (200) that define a channel (184) between the beam portions (190). The track assembly (440) also includes a sliding track member (370) that forms a portion of the cushion carrier (350). The sliding track member (370) includes a sliding frame (372) positioned in the channel (184) and having portions (442) positioned in sliding contact with portions (444) on the opposing surfaces (200) defining the channel (184).
摘要:
An apparatus (8) includes a seat (10) for an occupant (12) of a vehicle (14). The seat (10) includes a cushion portion (16) and a backrest portion (18). The apparatus (8) also includes an occupant protection device (70) that, when actuated, resists rearward movement of the backrest portion (18) of the seat (10) relative to the cushion portion (16) of the seat (10). A deflection mechanism (72) of the apparatus (8) is located in the backrest portion (18) of the seat (10) and is movable from a first position to a second position for actuating the occupant protection device (70). The deflection mechanism (72) is adapted to move from the first position to the second position without the backrest portion (18) moving significantly relative to cushion portion (16).
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 air bag module (12) is mounted for rotation with a vehicle steering wheel (14) which has a steering axis (90). The module (12) includes an inflator (10) having separately actuatable first and second stages (40, 40a). The stages (40, 40a) include, respectively, first and second chambers (60, 60a) and an inflation fluid source (120, 120a) in each chamber for providing inflation fluid to inflate an air bag (16). An axis (58) of the first chamber (60) extends parallel to and is spaced apart from an axis (58a) of the second chamber (60a). The axes (58, 58a) of the chambers (60, 60a) extend transverse to the steering axis (90) on opposite sides of the steering axis.
摘要:
An apparatus for controlling an occupant restraint system, such as an air bag (102), includes sensors (30, 36, 60, 64, 70, 80, 84, 86, 88, 90, 502, 504, 506) for sensing at least two parameters that could affect an occupant restraining function of the restraint system. The sensors are connected to a controller (24). A regulating valve (120) is connected to a reaction can (103) of the air bag (102) and is controlled by a control signal from the controller (24). The controller (24) selects one of a plurality of discrete control zones dependant upon the at least two sensed parameters and provides the control signal based on the selected one of the discrete control zones.
