Patent ID: 7686141

Claim:
A brake-equipped retracting device for a retractable member, comprising: a motor for generating a rotational force for opening a retractable member from a stored position to a deployed position; a returning spring member for returning the retractable member from the deployed position to the stored position by an elastic returning force generated by an elastic deformation thereof, wherein the degree of the elastic deformation increases in association with an action of opening the retractable member; a rotating member for transmitting a rotational force of the motor and an elastic returning force of the returning spring member toward the retractable member; a cord wound around the rotating member for restraining rotation of the rotating member; and a rotation-regulating mechanism for forcibly stopping rotation of the rotating member when a rotational speed of the rotating member exceeds a prescribed rotational speed, wherein the cord is adapted so that tensile force increases and the rotation-restraining force acting upon the rotating member increases in association with an action of opening the retractable member, whereas the tensile force decreases and the rotation-restraining force acting upon the rotating member decreases in association with an action of closing the retractable member; and the rotation-regulating mechanism has a centrifugal grip that can be moved by a centrifugal force generated in conjunction with rotation of the rotating member; a restricting spring member for restricting the movement of the centrifugal grip; and a stationary-side engaging part with which the centrifugal grip that has been moved by the centrifugal force in an amount equal to or greater than a prescribed amount can engage.
