PURPOSE: A portable, fracture preventing system is provided to protect elderly people or the handicapped from fracture when they accidently fall or collapse on the ground, by absorbing shock. CONSTITUTION: The portable, fracture preventing system includes a sensor(1), a controller(4), an air bag module(5), and a battery(6). The sensor(1) includes an acceleration sensor(2) and an angle sensor(3). The controller(4) includes a microprocessor for analyzing detected signals and performing appropriate processes. The angle sensor(3) detects limit of stability on both sides of a user and transmits it to the controller(4). When the user is about to fall, the controller(4) sends a signal to the air bag module(5), and the air bag instantly inflates for buffing the body from the ground.
