Abstract: A locking web retractor includes a spool mounted between side walls of a frame and rotatable in web take-up and pay out directions, and a locking apparatus including a toothed wheel rotatable with the spool, a movable component and a lock pawl. The movable component moves between a locking position in which it forces an engagement end of the lock pawl into engagement with the toothed wheel to prevent the spool from rotating in the web pay out direction, and an unlocking position in which the movable component does not force the engagement end of the lock pawl toward the toothed wheel. The lock pawl defines a counterweight at an opposite end and configured, in the unlocking position of the movable component, to cause the lock pawl to move in a direction which draws the engagement end of the lock pawl away from the toothed wheel.

Abstract: A seatbelt retractor assembly includes a disk having a cam surface and a cam follower surface. A lever that engages the cam surface when the lever is in a disengaged position and engages the cam follower surface when the lever is in an engaged position. The lever moves from the disengaged position to the engaged position in accordance with rotation of the disc. A Hall effect switch detects whether the lever is in the disengaged position or the engaged position.

Abstract: A seat belt system for motor vehicle applications incorporating a dual retractor restraint system with a portion of the seat belt webbing having a locally thick segment such as an inflatable seat belt portion. The dual retractors include electrically controlled actuating clutching mechanisms which operate to maintain the inflatable belt portion in a desired position relative to the upper torso of the seat occupant without requiring the inflatable belt portion to pass through the system D-ring or latch tongue or a high mounted retractor. When the occupant is donning the belt, the shoulder retractor is locked and the webbing is extracted from the lap retractor. Once the tongue is latched into the latch plate, the lap retractor is locked and movement of the occupant is permitted by allowing extraction of webbing from the shoulder retractor.

Abstract: Method for actuating a reversible belt pretensioner for pretensioning a belt webbing, the belt pretensioner having a drive which acts on the belt reel, and the seat belt having, as a belt extraction lock, a locking device which acts on the belt reel in the unwinding direction and whose locking can be released only if the belt reel is rotated through a specific angle of rotation in the winding-on direction. After the triggering of the belt pretensioner, the drive of the belt pretensioner for opening the locking device is actuated in an opening mode such that firstly, in a winding-on phase, the belt reel rotates through the specific angle of rotation in the winding-on direction. In a subsequent holding phase, the drive of the belt pretensioner is actuated for a predefinable holding time TH such that the belt reel is held in its angular position.

Abstract: The belt retractor for an occupant restraint system has a frame, a belt spool having a pair of flanges and rotatably mounted in the frame and a locking mechanism for selective blocking of the belt spool. A wheel member provided with an external toothing is mounted on one flange of the belt spool. A locking pawl is biased by a spring that engages with the wheel member. During the normal operating state of the belt retractor, the locking pawl is held by means of a solenoid so that it is disengaged from the wheel member.

Abstract: A load management system and method for controlling the activation sequence and times of activation of motor vehicle occupant restraints when a high g event, such as a crash, occurs. The system includes a microprocessor that processes inputs from a number of devices including seat weight sensor, an occupant spatial position detector, a buckle status detector, a belt sensor. The microprocessor is driven by a load management procedure that includes a high g event routine that controls the activation sequence of restraints so that the automatic locking restraint is first activated, followed by the pre-tensioner and then by the air bag. The load management procedure also includes an enable/disable procedure that controls the enabling and disabling of the restraints according to a number of variables including occupant weight, seat buckle status and belt extension status.

Abstract: A vehicle occupant protection system (30) comprises first and second lap belts (32 and 34) and first and second shoulder belts (36 and 38). A buckle assembly (90) is provided for interconnecting the first and second shoulder belts (36 and 38) and the first and second lap belts (32 and 34). At least one lap belt retractor (50) is operatively connected to the first and second lap belts (32 and 34) and is electrically actuatable, in response to receiving a first electrical locking signal, for locking the at least one lap belt retractor (50) to prevent withdrawal of the first and second lap belts (32 and 34). An occupant actuatable mechanism (160) is operatively connected to the at least one lap belt retractor (50) and is responsive to actuation by the vehicle occupant for providing the first electrical locking signal to the at least one lap belt retractor (50).

Abstract: In a seat belt retractor, when a collision predicting signal is generated from a collision predicting device, a motor rotates counterclockwise, and a pawl is thereby raised via a lever so as to move to a position contacting saw-blade teeth of a ratchet gear. In this state, when a rotational force is applied in the seatbelt-extraction direction, the rotation is prevented. On the other hand, the rotation in the seatbelt-retraction direction can be performed by pushing down the pawl with a diagonal portion of the saw-blade tooth of the ratchet gear.
