This technology is a safety device for fall victims that houses an airbag module and a folded parachute in the space between a leg harness worn by the worker and an outer wearable band. When a tilt sensor detects a fall posture, the control unit activates an igniter to inflate the airbag and deploy the parachute.
Falls from heights at construction sites often lead to major casualties because workers have no way to save themselves. Existing fall-protection lanyards are frequently left unfastened because they are inconvenient to detach and reattach every time a worker moves, leaving them vulnerable even while switching anchor points.
This technology features a wearable band made of first and second bands connected to rotate; the force of the inflating airbag releases one side, allowing the parachute to emerge, while parachute ropes are connected evenly around the harness. The tilt sensor uses a conductive fluid moving between two chambers separated by a funnel-shaped partition to connect reed electrodes. The igniter uses an explosive charge to drive a tipped plate that punctures a compressed gas canister, sending gas to the airbag. Applicable to high-rise structural and exterior work, bridge and transmission tower maintenance, and plant facility repairs, it slows the fall speed the moment a worker drops, even in areas where safety hooks cannot be used, thereby reducing injury.
