Abstract
Braking of independently-movable pivotable members is carried out by independent one-way clutch mechanisms which provide minimal braking force to the pivotable members in the vicinity of the limit points of their pivotable movement, and provide optimal braking force in a middle range of pivotable movement. The braking mechanism provided may operate on one or both of the pivotable members at the same time, each of the independent clutch mechanisms providing suitable braking force to compensate for the mass of the respective pivotable members.
