Restraining inflatable neck guard

Abstract: The restraining inflatable neck guard is adapted to be located around a person's neck when deflated. A source of compressed gas is coupled to the neck guard for inflating the guard. A normally closed electrically actuated valve is provided for releasing the compressed gas from the source for flow to the inflatable neck guard when actuated. A sensor is provided for sensing acceleration/deceleration forces in three mutually perpendicular directions and for producing electrical outputs having levels which are proportional to the forces sensed. A threshold device compares the electrical outputs with a threshold to actuate the valve when either of the electrical outputs reaches the threshold. The sensor may be employed to sense acceleration/deceleration forces in one direction only. Aircraft or vehicle systems may be used to initiate the inflation sequence. The restraining inflatable neck guard is designed to maintain distance between the neck and collar throughout the inflation process. The use of strength bars and shape molding spars provide controlled inflation of the inflatable neck guard.

Plastic bag handguard

Abstract: A handguard for plastic bags and like carrying items having thin loop-type handles which includes a planar palm guard member connected by a U-shaped bridging member to a finger guard portion. In vertical elevation, the palm, bridge and finger guard form a J-shape assembly. The handguard further includes a planar keeper which is joined at its upper edge to an upper end region of the palm guard to form a rigid hinge which forces the planar keeper outwardly in a sprung-open position so that the lower edge of the keeper is retained by the upper edge of the finger guard portion. In use, the handguard is held generally vertically in the user's hand with the palm portion resting against the user's palm and the U-shaped bridging member supported by the user's fingers. The loops of the plastic grocery bags are then picked up so that they are received within the trough of the U-shaped bridge member. The keeper flap is sufficiently flexible so that it is very easy to slip the grocery bag loops into the handguard yet is normally biased to the closed position to ensure that the handguard will not become unintentionally separated from the bag handles when the bag is set down.
