In a webbing take-up device, an angle from one end portion toward another end portion of a second clutch spring in a direction of winding of a coil portion from the one end portion toward the another end portion of the second clutch spring is 270°. Therefore, in a case in which the one end portion of the second clutch spring is rotated toward a side of the direction of the winding of the coil portion, one end side portion of the second clutch spring is displaced so as to bulge-out toward a side opposite to a side toward which another end side portion bulges-out.

System and method for obtaining and recording information about cargo includes a frame defining a cargo-receivable compartment, a position determining system at least partly on the frame and that allows for determination of position of the frame, an identification system on the frame that obtains information about cargo when present in the compartment, a memory component that receives and records information about position and movement of the frame, and the obtained information about cargo when present in the compartment in association with a unique identification of the frame, and a communications system on the frame to enable communication of information to and from the memory component.

In a webbing take-up device, in a state in which a stopper of a force limiter stopper mechanism has been brought into abutting contact with a stopper abutment portion resulting in rotation of a spool in a pull-out direction having become limited, the stopper is disposed on the inside of a flywheel hole portion of a flywheel body of a flywheel of a second force limiter mechanism. For this reason, deformation of the stopper outward in its radial direction can be suppressed by the flywheel body of the flywheel.

A webbing take-up device in which, when a pretensioner mechanism is activated and turning of a pinion relative to a spool is allowed, a lock pawl is turned by the pinion and a trigger wire is sheared by the lock pawl. Thereafter, the pinion turns more relative to the lock pawl and shears a lock pin of the lock pawl. Hence, the lock pawl turns and activates an activation mechanism. Therefore, the activation mechanism may be activated without a torsion shaft of a force limiter mechanism allowing turning of a lock base in the take-up direction relative to the spool.

A switching mechanism (100) in a force limiter mechanism of a seat belt retractor including: a locking mechanism including a locking element (68) that locks a torque tube (64) with respect to a spindle (61) so that the torque tube (64) rotates together with the spindle (61) and a spindle ring (70); a switch ring (120) rotatable to unlock the locking mechanism; and a switch housing (101) that stores the switch ring (120), a switch piston (115) adapted to activate the switch ring (120). A switching gas generator (116) generates gas for pushing out the switch piston (115) upon activation of the switching mechanism. The switch housing (101) of the switching mechanism (100) has a protrusion (110) that protrudes in an incoming direction of an operated part (122) at an abutment part hit by the switch ring (120) rotated by the switch piston (115) to control movement of the switch ring.

A vehicular belt tactile apparatus is provided. The apparatus includes a buckle, a belt configured to be fastened to the buckle and at least one air pouch disposed at a portion of the belt that contacts the body of an occupant when the belt is fastened to the buckle. An air controller generates a control signal when the belt is fastened to the buckle. The buckle includes an air supply unit that is configured to inject air into the at least one air pouch through the belt or to discharge air from the at least one air pouch in response to the control signal.

A vehicle occupant protection device includes a seat belt device having a variable force limiter mechanism that can change a force limiter load that an occupant who is sitting on a vehicle seat receives from a seat belt at a time of a frontal collision of a vehicle, an airbag device that deploys an airbag toward the front of the occupant at the time of the frontal collision, a seating position detection unit that detects a seating position at which the occupant is seated, and a control unit that reduces the force limiter load if, compared to a case in which the occupant is positioned within a standard seating region, the seating position of the occupant detected by the seating position detection unit is further toward a vehicle rear than the standard seating region and is within an airbag protection region in which the occupant is protected by the airbag.

A seat belt system for protecting an occupant of a vehicle, the system having seat belt webbing connected to a seat belt retractor that includes (a) a frame; (b) a spool with the seat belt webbing wound around, wherein the spool is rotatably mounted to the frame and configured to rotate in a webbing extraction direction and a webbing retraction direction; (c) an energy absorbing device for absorbing energy when the spool is rotated in the webbing extraction direction after an emergency event has occurred; and (d) a mechanism for selectively cancelling the operation of the energy absorbing device by preventing motion of the spool in the webbing extraction direction.

The invention relates to an active restraint system (1), comprising a seat belt retractor (3), having a frame (2) and a belt reel (4) with a belt webbing (10) wound thereon and rotatable supported by the frame (2) for allowing winding and unwinding the belt webbing (10). An electric disc motor (28) comprising a rotor (30) and a stator (32) is attached to the belt reel (4). The rotor (30) is directly attached by an attachment (31) to the belt reel (4). The restraint system further comprises a control unit (40) connected to the disc motor (28) and adapted to control the disc motor (28) to drive the belt reel (4) in accordance with a determined belt motion profile.

A belt retractor comprises a frame (10), a belt reel (12) rotatably arranged in the frame (10) and having a first end (16) and an opposite second end (17) as well as comprising a blocking mechanism (18) arranged at an end face of the belt reel (12) by which the belt reel (12) can be blocked within the frame (10). The belt retractor further comprises an axially extending first load limiter which is releasably coupled to the belt reel (12) by means of a disconnecting clutch (24), a second load limiter which is coupled to be rotationally fixed to the first load limiter or a hub, and a third load limiter which can be coupled to be rotationally fixed to the belt reel (12) by means of a connecting clutch (38). Moreover, a method for controlling such belt retractor is provided.
