Abstract
A seat belt retracting and winding device of the type including spring means including first and second springs imparting a torque to the winding shaft so as to retract the seat belt wound therearound, and control means for changing the torque applied to said winding shaft by the spring means depending upon whether an occupant fastens the seat belt and is restrained by the tension thereof or the occupant releases the seat belt so that the latter is being wound. Securely retaining the outer end or the other end of the second spring is disclosed. To ensure more reliable and dependable operation of the control means, a pawl included in the control means has an improved shape at the engaging end thereof and is positively prevented from the displacement in the direction of the axis of its pivot pin. Thirdly, erratic assembly of a friction disk and a cam disk of the control means may be avoided by the improved designs thereof. Fourthly, when the seat belt is retracted and rewound, the engagement of the pawl with the cam disk may be completely prevented so that damage to the device may be prevented and consequently reliable and dependable operation may be ensured. Finally, the axial movement of the first spring may be prevented, and therefore, the satisfactory operation of the device may be ensured.
