Abstract: A seatbelt retractor integrated with an electronic control unit. A motor is disposed above both side walls of a frame and on the same side as a spool with respect to a back board. The motor is detachably fixed to at least one of the back board and the both side walls and of the frame. The ECU is detachably mounted to an upper stay extending upward from the back board of the frame and to be mounted to the vehicle body. In this manner, the motor and the ECU are integrated with a seatbelt retractor. Since the ECU is mounted to the upper stay, the weight of the ECU is dispersed not only to the main body of the seatbelt retractor but also to the upper stay. Thus, the vibration of the seatbelt retractor may be reduced.

Abstract: A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by mechanism of an electric motor, removes slack of the seat belt and controls the restraining feeling on a vehicle occupant to be as little as possible. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is adapted to control a motor to perform an action of increasing seat belt tension to wind up a seat belt which is excessively unwound from the spool when a vehicle occupant wears the seat belt and to be driven according to such a setting that, at the initial stage of the action of increasing the seat belt tension, the tension increasing rate until the seat belt tension reaches a target tension is lower than a predetermined rate.

Abstract: A seat belt retractor (6) according to the present invention, when mounted on a vehicle body, has an ECU (16) laid out in such a manner that an ECU connector (16c) faces a vehicle side connector (18) mounted to a predetermined position of the vehicle body. Such a vehicle side connector (18) is connected to a power supply (17). Such a layout of the ECU (16) allows the ECU connector (16c) to be directly electrically connected to the vehicle side connector (18).

Abstract: A seatbelt control apparatus including seatbelt control means that controls a motor for retracting a seatbelt; and motor current detecting means that detects a current of the motor. The seatbelt control apparatus further includes jamming determination means, indicator detecting means, and threshold value setting means. The jamming determination means determines whether or not the seatbelt is jammed during take-up operation on the basis of whether or not the motor current detected by the motor current detecting means exceeds a threshold value for jamming determination. The indicator detecting means detects an indicator of a current versus load characteristic of the motor. The threshold value setting means sets the threshold value for jamming determination on the basis of the indicator detected by the indicator detecting means.

Abstract: A seat belt retractor includes a seat belt winding device for winding up a seat belt by actuation of a motor and a control unit that repeats a process of stopping the actuation of the motor on an overload of the motor and restarting actuation of the motor after lapse of a predetermined time period. The control unit includes a detection module for detecting an occupant getting on or off a vehicle and a determination module that, using criteria, determines whether or not actuation of the motor is to be restarted. The criteria when the occupant enters the vehicle is different from when the occupant exits the vehicle. The criteria are provided so that the determination module is more likely to determine that the actuation of the motor is not to be restarted when the occupant enters the vehicle as compared to when the occupant exits the vehicle.

Abstract: The disclosed seat belt retractor and device can be useful to reliably warn the vehicle occupant of various hazards, such as obstacles or the dozing of the driver. The seat belt retractor and device can comprise an electric motor, a spool for retracting a seat belt to restrain a vehicle occupant, and a controller for controlling the driving of the electric motor. The controller can be configured to control the driving of the electric motor so that several operations for increasing and decreasing the tension acting on the seat belt by the spool are repeated for warning the vehicle occupant. In addition, the controller can be configured to control the driving of the electric motor so that a motion of the spool in a seat belt retracting direction is larger in an initial operation relative to subsequent operations.

Abstract: A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by an electric motor, warns a vehicle occupant. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is structured such that a motor is controlled to repeat an action of increasing and decreasing the tension acting on a seat belt a plurality of times according to a setting that the seat belt tension at the initial stage of each action overshoots a predetermined target tension, for the purpose of warning a vehicle occupant who wears the seat belt.

Abstract: As an occupant releases the latching between a buckle and a tongue, a seat belt retractor winds up the seat belt at a winding-up speed S1 as a first high speed. Accordingly, the seat belt moves away from the occupant immediately. As a time period (T1-T0) elapses from the buckle release, the seat belt retractor winds up the seat belt at a winding-up speed S2 as a low speed. Accordingly, the seat belt is slowly wound up so that the tongue is less likely to strike and thus scratch an interior panel. As a time period (T2-T1) further elapses, the seat belt retractor winds up the seat belt at a winding-up speed S3 as a second high speed. Accordingly, the winding of the seat belt is promptly completed so that the seat belt is less likely to be caught by a door when the occupant gets out of the vehicle.
