Further, at least one of the first rail and the second rail is moved in a second direction to cause the lift cords to wind on the lift cord pulleys, with the lift cord pulley shaft rotating in an opposite direction.

Abstract: A difference in limiting torques of rotation between a spring and a rotary member is increased without increasing a number of coils of the spring. In a webbing winding device, an outer diameter of a clutch wall of a clutch wheel increases from a flange side to a stopping flange side of the clutch wall. When a clutch spring is tightly wound on the clutch wall, the clutch spring is subjected to a movement force toward the stopping flange side. Thus, a winding force of the clutch spring onto the clutch wall is effectively increased. Therefore, a difference in limiting torques of rotation between the clutch spring and the clutch wheel between when the clutch spring is not tightly wound on the clutch wall and when it is wound on the clutch wall is increased, without increasing a number of coils of the spring.

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.
