<p>PROBLEM TO BE SOLVED: To dissolve discomfort given to a seating person by reflecting motion of a body of a seating person to seat belt tension control with a simple algorithm without detecting a drawing amount.SOLUTION: A control device 30 (control unit) controls a motor 23 so as to generate belt taking-up tension of a belt 13 only when first synthetic acceleration comprising at least one of front direction acceleration, left direction acceleration, and right direction acceleration of a vehicle is a first predetermined value or more (for example, 3.5 G), detected by an acceleration detection unit. At this time, the motor 23 is controlled so that, as larger the first synthetic acceleration which is equal to or more than the first predetermined value, the taking-up tension of the belt 13 becomes smaller.</p> |
