SEAT BELT RETRACTOR DEVICE FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JPS63269755
Kind Code:
A
Abstract:
PURPOSE:To eliminate the inhibition of the draw of a belt at the time of opening the door so as to enhance practicability by providing such an operating member as a weight or the like for inhibiting the rotation of a winding shaft member according to the horizontal acceleration of a door, and making the action sensitivity of the operating member variable in accordance with the opened/closed state of the door. CONSTITUTION:A ratchet wheel 8 is connected to the end portion of a retractor shaft urged in the belt winding direction by the action of a winding spring, and a rachet lever 9 is engagable with plural ratchets 8c formed on the outer periphery portion thereof. The ratchet lever 9 is engaged with the ratchets 8c by the action of a weight 10 which is titled when the horizontal acceleration of a door exceeds a predetermined value, thereby inhibiting the rotation of a shaft 7. And further, there is provided a member 19 moved upward when the opening of the door turns a door switch 4 on so as to magnetize a solenoid 21, and the upward movement of the member 19 makes the weight 10 supported also on a projected portion 19b, thereby enabling the sensitivity of the weight 10 dulled.
