INFLATABLE BODY AND HEAD RESTRAINT

This investigation established the feasibility of using an automatically inflatable restraint system as an alternative to the conventional restraint worn by helicopter crewmen. This type restraint provides increased crash protection because it provides automatic pretensioning which forces the occupant back in his seat, thereby reducing dynamic overshoot; reduces strap loading on the wearer when the inflated restraint is compressed during crash loading; reduces the concentration of strap loads on the body because of the increased bearing surface provided when the restraint is inflated; reduces head rotation and whiplash induced trauma.
