Abstract
A garment such as a vest or jump suit containing one or more inflatable gas-bags which will automatically expand upon appropriate signals from remote and garment contained deceleration sensors. A unique coded signal system is employed to insure that in fact inflation is required of the gas-bag or gas-bags prior to inflation to prevent accidental inflation.
Claims13
A garment for personal crash impact protection comprising:
- said garment designed to enclose at least the upper torso of a person, said garment is non-restraining to the normal routine of the wearer;
- a plurality of first crash sensors located in a fixed position remote from the garment;
- a plurality of second crash sensors located in close relationship to the garment;
- each of said plurality of first and second crash sensors provide a separate coded output signal when a predetermined threshold level of deceleration is sensed;
- at least one inflatable air bag located in said garment which when inflated substantially encompass the torso of the wearer adjacent thereto;
- and
- inflation means connected to receive said output signals from said plurality of first and second crash sensors for inflating said at least one inflatable air bag when a preselected number of signals are simultaneously received from a selected number of said plurality of first and second crash sensors.
