摘要

The apparatus has a tether (50) extending between an inflatable protection device and a vent unit (46). The vent unit is moved to an open condition to enable fluid flow through a vent opening. The vent unit is moved back to a closed position due to tension in the tether. The tension results from inflation of the protection device away from a support unit by more than a preset distance.
