  • Patent number: 7793984
    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.

  • Patent number: 7753158
    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.

  • Patent number: 7712567
    Abstract: The seat belt retractor is provided that comprises an electric motor; a spool operatively associated with the electric motor for winding and unwinding a seat belt for occupant restraint; and a controller. The controller can be configured to control a drive of the electric motor based on a seat belt storage starting condition defined by information about a state of the seat belt relative to a vehicle occupant and information about a state of a vehicle door corresponding to the seat belt. The controller can be configured to control the drive of the electric motor to rotate the spool to wind up the seat belt when the seat belt storage starting condition is satisfied and to temporarily stop the rotation of the spool for a time period when a seat belt load acting on the seat belt exceeds a predetermined amount. The time period can be set according to a satisfaction pattern of the seat belt storage starting condition.

  • Patent number: 7681683
    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. The control unit, under a predetermined condition, repeats a process of stopping the actuation of the motor when an overload of the motor is detected and restarting the actuation of the motor after a lapse of a predetermined time period. The control unit includes a timer for clocking the time period from the start to the stop of the actuation of the motor, a counter for counting up the number of times of starting the actuation of the motor, and a determination module that based on the result of the timer and the counter determines whether or not actuation of the motor, which is stopped by the detection of an overload, is to be restarted.

  • Patent number: 7681303
    Abstract: Embodiments of the present invention provide a method of manufacturing a magnetic head slider, the method being adapted so that throat height of a main magnetic pole piece of a perpendicular recording magnetic head can be controlled with high accuracy. According to one embodiment, a first Electrical Lapping Guide element (ELG) is disposed on the same layer as a plated underlayer of a shield of one write head in a row bar, and other ELGs are disposed on the same layer as that of a main magnetic pole piece of another write head. Front end positions (Tops) are detected from changes in resistance values of the other ELGs and an ending position of lapping is calculated. Since the front end positions (Tops) of the other ELGs are accurate, it is possible to assign a correlation to throat height “Th” of the main magnetic pole piece and the resistance value of the first ELG by detecting this resistance value existing when the front end positions (Tops) are detected.

  • Publication number: 20100001503
    Abstract: [Problems] To allow an occupant to easily wear a seat belt without twisting his or her body when the occupant sits in a seat. [Means for Solving the Problems] When a door sensor 60 detects the opening of a door, a motor is driven to wind up a seat belt 2 so as to move a belt guide 4 against biasing force of a spring 9, thereby evacuating the seat belt 2 to a rear side of a vehicle relative to a seat back 1a. When the door sensor 60 detects the closing of the door and a seat sensor 61 detects the sitting of the occupant, the motor is driven in the reverse direction to make a clutch mechanism 34 in the disconnected state so as to protrude the seat belt 2 in the forward direction of the vehicle by the biasing force of the spring 9.

  • Patent number: 7634850
    Abstract: Embodiments of the present invention allow control over the element height of read and write heads without damage to a lapping surface table when an air-bearing surface is lapped with a row bar or magnetic head slider tilted. According to one embodiment, the air-bearing surface is lapped with the row bar tilted in the longitudinal direction of a slider to compensate element height-wise positional deviations of the read head and the write head. The lapping is performed while changing an inclination angle stepwise and swinging the row bar in the longitudinal direction of the slider centering around an inclination angle at each step. Thus, the element heights of the magnetic pole piece and the read element can be controlled without damage to a lapping surface table.

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.

  • Patent number: 7600600
    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.
