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.
