发明名称 RETRACTABLE LIFELINE SAFETY DEVICE
摘要 A retractable lifeline safety device usable at heights above the ground. The safety device is attached to the structure on which the worker is performing the task, and a lifeline such as a cable is withdrawn from the housing thereof, the end of which is attached to a belt or harness worn by the worker. The cable may be easily drawn out of the housing in response to the worker moving about normally in the appropriate work space, and the cable is automatically drawn back into the housing of the safety device as the worker draws closer thereto. However, should the worker fall, a brake mechanism within the safety device is automatically engaged..by a sprocket and pawl system, stopping the worker's descent.
