BALLISTIC POWERED INERTIA REEL

摘要

A ballistic powered inertial reel device comprises an inertia unit and a ballistic powered unit. The inertia unit includes a reel shaft and a webbing wound on the reel shaft. A reel lock has a disengaged orientation with the reel shaft during normal operation and an engaged orientation to prevent rotation of the reel shaft during an emergency. A control dog drives the reel lock. A geared cam rotates to drive a lock rod which operates against the control dog to drive the reel lock into the engaged orientation. The ballistic powered unit comprises a flywheel coupled to the geared cam. A piston drives the flywheel and a rewind spring couples the flywheel to the reel shaft. Actuation of the piston rotates the flywheel to cause the rewind spring to rotate the reel shaft to rewind the webbing and rotate the geared cam to lock the reel lock.
