Abstract
Abstract Subject invention relates to novel and improved apparatus for maintaining an individual''s head in an optimum position with respect to other portions of his body during the application of high acceleration and/or deceleration forces thereon. The improved apparatus includes a normally noninflated inflatable bag which is positioned beneath the pilot''s chin and which is removably secured at opposite ends to the ear lobe portions of the pilot''s helmet, and means for quickly inflating the bag when a high acceleration or deceleration force occurs. The bag is designed such that in its noninflated condition, it may be folded into a compact band that is readily and comfortably attached to the chin strap of the helmet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
In combination with a protective helmet having lobes that extend downwardly opposite the ears of an individual wearing said helmet and having a chin strap extending between said lobes apparatus for maintaining the individual''s head in an optimum position with respect to his neck, shoulders and other parts of his body during the application of high acceleration forces on the body, said apparatus comprising: a. a normally noninflated inflatable bag which is adapted to be positioned beneath the individual''s chin and which is removably secured at opposite ends to the ear lobe portions of the helmet, said bag being of such a volume, when inflated, to prevent the chin of the individual from contacting his chest area; b. and means for inflating the bag including a source of pressurized gas and means to activate same.
Claim 2
Dependent Claim
135 words
In combination with a protective helmet having lobes that extend downwardly opposite the ears of an individual wearing said helmet and having a chin strap extending between said lobes apparatus for maintaining the individual''s head in an optimum position with respect to his neck, shoulders and other parts of his body during the application of high acceleration forces on the body, said apparatus comprising: a. a normally noninflated inflatable bag which is adapted to be positioned beneath the individual''s chin and which is removably secured at opposite ends to the ear lobe portions of the helmet, said bag being of such a volume, when inflated, to prevent the chin of the individual from contacting his chest area; b. and means for inflating the bag including a source of pressurized gas and means to activate same.
Claim 3
Dependent Claim
28 words
The apparatus substantially as described in claim 1 and further including means for maintaining the inflatable bag in a compact folded condition until a predetermined acceleration force occurs.
Claim 4
Dependent Claim
26 words
The apparatus substantially as described in claim 2 wherein the inflatable bag when in its folded condition is secured to said chin strap on the helmet.
Claim 5
Dependent Claim
