Abstract
A bulletproof equipment for protecting personnel against a projectile fired from a gun or the like. The equipment includes a inflatable bulletproof air bag for protecting a targeted individual from fire of a weapon; an air tank for ejecting compressed gas or air into the air bag; a high speed fan for feeding air into the air bag when the air bag is punctured; a controller for controlling the associated components; and a power supply for applying electric current.
Claims16
A bulletproof device comprising:
- a bulletproof air bag for protecting a targeted individual from a projectile fired from a weapon;
- inflation means in communication with the air bag for injecting compressed gas or air into the air bag for inflating the air bag within a predetermined time period;
- pressure retention means comprising a high speed fan in communication with the air bag for feeding air into the air bag to retain a pressure in the air bag at a predetermined value so that the airbag retains its inflated shape subsequent to the air bag being punctured;
- control means for controlling at least one of an actuation of the inflation means and the retention means, and
- detection means for detecting a reduction in pressure in the airbag, said detection means providing a feedback signal to said control means with regard to a status of the airbag.

A bulletproof device comprising:
- a bulletproof air bag for protecting a targeted individual from a projectile fired from a weapon;
- an air tank in communication with the air bag for injecting compressed gas or air into the air bag to inflate the air bag within a predetermined time period by remote control of a user;
- a high speed fan in communication with the air bag for feeding air into the air bag to restore the deflated air bag to its inflated shape subsequent to the air bag being punctured by a projectile;
- a controller for controlling a solenoid operated valve of the air tank, the high speed fan and a driving motor of the bulletproof air bag;
- and
- a power supply for applying electric current to the solenoid operated valve, the high speed fan and the driving motor of the air bag.
