A ballistic powered inertial reel device, comprising: a) an inertia unit comprising: i) a reel shaft configured to rotate in an unwinding direction and an opposing rewinding direction; ii) a webbing wound on the reel shaft and configured to restrain a user within a seat, the webbing being unwound and rewound upon rotation of the reel shaft; iii) a reel lock mechanism coupled to the reel shaft, the reel lock mechanism being in a disengaged orientation with the reel shaft during normal operation and being in an engaged orientation with the reel shaft to prevent rotation of the reel shaft and unwinding of the webbing during an emergency; iv) a control dog coupled to the reel lock mechanism, the control dog operable to drive the reel lock mechanism from the disengaged orientation to the engaged orientation; v) a lock rod configured to engage the control dog, the lock rod movable between a disengaged position and an engaged position wherein when in the engaged position the lock rod operates against the control dog to drive the reel lock mechanism into the engaged orientation; and vi) a geared cam coupled to the lock rod, the geared cam rotatable from a first position wherein the lock rod is in the disengaged position to a second position wherein the lock rod is moved to the engaged position; and b) a ballistic powered unit comprising: i) a flywheel having a smooth portion and a geared portion, the geared portion coupled to the geared cam; ii) a piston adapted to drive the flywheel; and iii) a rewind spring coupling the smooth portion of the flywheel to the reel shaft, wherein actuation of the piston during the emergency rotates the flywheel in a first direction to thereby (i) cause the rewind spring to rotate the reel shaft in the rewind direction to rewind the webbing and secure the user against the seat, and (ii) cause the geared portion to rotate the geared cam from the first position to the second position to lock the reel lock mechanism and prevent rotation of the reel shaft in the unwinding direction. a) an inertia unit comprising: i) a reel shaft configured to rotate in an unwinding direction and an opposing rewinding direction;
