The positioning calling device 6 is respectively placed in the outer side pockets of the upper garment 1 and the lower garment 2, and the reminding device 5 and the positioning calling device 6 are respectively connected with the reaction type inflating device 3.

A protective layer is wrapped outside the reaction type inflating device 3, the material of the protective layer is mainly made of composite material non-woven cloth of high-performance fiber, because the high-performance fiber is a chemical fiber with special physical and chemical structure, performance and application or special function, generally the fiber with the strength of more than 17.6cN/dtex and the elastic modulus of more than 440cN/dtex, it has the functions of strong corrosion resistance, low abrasion, high temperature resistance, radiation resistance, flame resistance, high voltage resistance, high elasticity, reverse osmosis and the like, these high-performance fibers are much higher than the energy absorption capacity of the typical material, which is also called soft body armor because it imparts the ballistic function of the armor, so the utility model discloses a set up this inoxidizing coating, it has kept original compliance promptly, sets up the comfort level that can not reduce the dress in the dress, can prevent effectively again that reaction type aerating device 3 from aerifing the damage that the micro-explosion that the in-process leads to because of the accident situation produced the user.

The three-axis acceleration sensor has the characteristics of small volume and light weight, can measure the spatial acceleration, and can comprehensively and accurately reflect the motion property of an object. On one hand, to accurately know the motion state of an object, components on three coordinate axes of the object need to be measured because the acceleration is a space vector; on the other hand, when the direction of the human body movement is not known in advance, only the three-axis acceleration sensor is used to detect the acceleration signal. Because the triaxial acceleration sensor is also based on the gravity principle, the triaxial acceleration sensor can realize double accelerationThe inclination angle of the positive and negative 90 degrees of the shaft or 0-360 degrees of the double shaft is higher than that of the double shaft acceleration sensor by the later correction precision of more than 60 degrees of the measurement angle.

The working principle of the micro ignition device and the gas generator is that the micro ignition device ignites by utilizing the electrothermal effect to electrify the short thin metal wire between the two metal rods, so that a large amount of heat is generated instantly, an ignition agent in the gas generator is ignited (the effect of the ignition agent is similar to that of a match head charge part to generate sparks), and the ignition agent enables the nitrogen gas generating agent to generate nitrogen gas and enables the nitrogen gas to be discharged from an outlet of the gas generator through a filter screen.

The air bag 4 is limited in the detachable interlayer and is not in contact with a human body, the air bag 4 can be made of an airtight TPU textile composite material, the composite material is formed by coating TPU rubber materials with specific performance on high-strength fiber fabrics such as nylon, terylene and the like, and the air tightness is good.

As shown in fig. 4, the operating principle of the reactive inflator 3 is: the acceleration sensor collects speed signals when a user wears clothes, the central processing unit processes and analyzes the speed signals transmitted by the acceleration sensor and judges whether the micro ignition device is started or not, when the speed signals suddenly change, the central processing unit starts the micro ignition device, otherwise, the micro ignition device is in a closed state; when the micro ignition device receives an ignition signal transmitted by the signal detection device 31, a heating wire circuit in the micro ignition device is switched on, so that the temperature of the heating wire is raised to generate heat energy, the high heat ignites the gas generator to generate nitrogen, the released nitrogen enters the air bag 4, the air bag 4 is inflated, and the air bag is filled with the reactive type inflating device 3 for about 1-2 seconds. At the same time as the signal detection means activate the micro ignition means, the signal detection means also activate the location calling means 6. Because the gas generator adopts chemical substances and instantly generates gases such as nitrogen, water vapor and the like through thermochemical reaction, the gas generator is safe and reliable for users, and the inflation mode is the same as the principle of an automobile inflatable airbag. In order to prevent the injury to the user caused by the rupture of the air bag 4 due to the overfilling after the user falls down, the gas generated by the reaction type inflating device of the utility model can only fill the air bag 4 to about 75-85%.
