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 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: [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.

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: A clock enable (CKE) control circuit (112) is provided between a memory control circuit (111) and a SDRAM (120). When a system is in, e.g., a sleep state, the CKE control circuit (112) controls a CKE signal outputted to the SDRAM (120) such that it is fixed to a Low level. As a result, it is possible to halt a power supply provided to the memory control circuit (111), while maintaining the low-power-consumption mode of the SDRAM (120), so that power consumption resulting from a leakage current is suppressed. In addition, it becomes also possible to reset the memory control circuit (111), while maintaining the low-power-consumption mode of the SDRAM (120).
