<p><P>PROBLEM TO BE SOLVED: To provide an effect that can promptly actuate a seat at emergency while keeping the operation feeling of a normal state except for the emergency. <P>SOLUTION: A transmission mechanism 40 wherein a belt 42 is wound around a first pulley 44 and a second pulley 46. The first pulley 44 expands in the width of a part holding the belt 42 as rotation speed increases. The second pulley 46 narrows in the width of a part holding the belt 42 as the rotation speed increases. When a collision is not estimated, a seat actuator is driven at first driving speed, thereby adjusting an angle of a seat back through the transmission mechanism 40. When the collision is estimated, the seat actuator is driven at second driving speed higher than the first driving speed, thereby increasing a gear ratio of the transmission mechanism 40 to adjust the angle of the seat back. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
