  • the system aims to reduce the dependency on the airbags for the purpose of upper body injury evasion and especially the face safety. Further, the sliding adjustments in the system has been shifted from the platform fixed on the floor of the vehicle to the plunger of the piston. Also, the system is entirely a new measure to ensure the leg safety by making the use of cable holders which are to be locked in the calves of the front passengers’ legs and power spring for their retraction.
