ABSTRACT:
A safety harness device of the inertia type wherein the rewind spring is connected to a fluid pressure actuated portion that is normally inoperative during ordinary operations of the safety harness, but which, when actuated by the user, serves to pull upon the rewind spring to rapidly haul in the user, without injury to him however, against the back of his seat prior to ejection regardless of accelerating forces obtaining at that time. A pressure responsive regulator valve provides substantially constant flow of control fluid to control the velocity of the haulback force.
