Document Type and Number:
Japanese Patent JPS5332128
Kind Code:
B2
Abstract:
A vehicle passenger restraining belt extends from a retraction reel and one or both opposite faces of the belt are frictionally engaged by respective brake members which are swingable about transverse axis. The brake member has a curved friction brake face spaced from its swing axis distances which increase in a direction opposite to the belt withdrawal direction. As a withdrawal force is applied to the belt its withdrawal is frictionally prevented by the brake member and with increased force the brake member is advanced to retract its point of engagement with the belt to increase the angle between a line extending perpendicularly to the belt from the brake member axis and a line between the axis and the point of engagement until such angle exceeds a predetermined angle whose tangent equals the coefficient of friction between the brake and belt faces and the belt slips along the brake with the kinetic energy of the passenger being absorbed. The brake is normally disabled by a solenoid which is energized through a series of connected inertia switch, a manually actuated switch and a seat occupation actuated switch.
