ABSTRACT:
The present invention provides a centrifugal brake which, according to one aspect of the invention, has a center hub from which extend flex members terminating in tabs extending from the flex members. Disposed on the opposite side of each flex member from the tab, is a friction portion. The friction portion is brought into contact with a braking surface when the centrifugal brake is rotated at sufficient speeds so that the centrifugal force acting on the tabs causes the flex members to bend and bring the friction portions into contact with the braking surface thereby resisting further acceleration of the centrifugal brake.
