Operating system for tightening the shoulder straps. This is done mechanically on the ground using a lever on the left side of the seat body,
allowing the pilot's shoulders to be loosened or tightened along a 230mm travel length.
The Emergency Retraction System is activated by means of the dual ejection handles, during the initial movement of which the PK-3M1 type explo-
sive charge is activated, with the help of which the pilot's shoulders are forcibly pulled to the seat backrest and the arm restraints are extended
before the ejection itself. They remain in this extended position until the moment of firing the first stabilizing parachute rod in 0 to 1.6 seconds
Leg restraint system uses clips under the forward part of the seat shell.
