Description

An airbag capable of being installed in clothes and its application method

technical field

The invention relates to an airbag and a method for using the same.

Background technique

In winter in the north, due to icy roads, elderly people often fall and get injured. Existing protection mode is exactly to wear the protective pad that sponge or foaming material are made in clothes. This method will cause the wearer to have bloated clothes and inconvenient movement. At the same time, due to the limited thickness, it is difficult to provide sufficient protection for users.

Contents of the invention

The present invention solves the problem that the existing method of putting a protective pad made of sponge or foaming material in the clothes to prevent people from falling will cause the clothes to be bloated and inconvenient for the user to move, and because the thickness of the sponge or foaming material is limited, it cannot provide protection for the user. The problem of providing adequate protection presents an air bag capable of being installed in clothing and a method of use thereof.

An airbag capable of being installed in clothes according to the present invention includes an airbag body, and is characterized in that the airbag includes a quick inflation device, a gravity sensor, a trigger circuit and a battery;

The fast inflation device is fixedly installed at the opening of the airbag body, the switch signal input end of the fast inflation device is connected to the trigger signal output end of the trigger circuit, the trigger signal input end of the trigger circuit is connected to the gravity signal output end of the gravity sensor, and the battery is used for powering the trigger circuit .

Utilize above-mentioned practical method of a kind of air bag that can be installed in the clothes, the concrete steps of this method are:

Step 1. Fix the fast inflation device, gravity sensor, trigger circuit, battery and airbag body in the clothes;

Step 2, turn on the power switch of the trigger circuit, the trigger circuit detects the weightlessness time of the gravity sensor in real time, when the gravity sensor detects that it is in the weightlessness state for more than 0.2 seconds, the trigger circuit triggers the fast inflation device;

Step 3: Trigger circuit The quick inflation device is triggered by the trigger circuit to inflate the airbag body.

The airbag installed in the clothes of the present invention is small in size and light in weight and can be easily stuffed into the interlayer of the clothes or trousers of the person in need. At the same time, when the airbag is installed in the clothes, the weight loss exceeds 0.2 The second-time quick inflation device inflates the airbag body, and the airbag is inflated before the person touches the ground, which reduces the impact force between the fallen person and the ground, reduces the probability of the person falling, and provides sufficient protection for the user.

Description of drawings

Fig. 1 is a schematic connection diagram of an airbag that can be installed in clothes according to the present invention.

Detailed ways

Specific embodiments 1. This embodiment is described in conjunction with FIG. 1. An airbag that can be installed in clothes according to this embodiment includes an airbag body 5. It is characterized in that the airbag includes a quick inflation device 1, a gravity sensor 2, Trigger circuit 3 and battery 4;

The quick inflation device 1 is fixedly installed at the opening of the airbag body 5, the switch signal input end of the quick inflation device 1 is connected to the trigger signal output end of the trigger circuit 3, the trigger signal input end of the trigger circuit 3 is connected to the gravity sensor 2 gravity signal output end, the battery 4 is used to supply power to the trigger circuit 3.

In the device of the present invention, when the gravity sensor connected to the trigger circuit senses the weightless state and the duration is greater than 0.2 seconds, it takes about 20 centimeters of free fall, and the trigger circuit releases the current to trigger the inflation system to quickly release the gas into the airbag . The airbag is inflated within 0.05 seconds, providing buffer protection for the position where the person falls and touches the ground, effectively preventing the person from falling. The total time from sensing to weightlessness to the completion of airbag inflation is 0.25 seconds, which is about the time for an object to fall freely from a height of 30 cm. This time can not only complete the release of the airbag before the personnel falls and touch the ground, but also prevent false triggering caused by the personnel's daily activities. Airbags can be installed on the knees, hip bones, coccyx, back, chest, and elbow joints.

Embodiment 2. This embodiment is a further description of the airbag that can be installed in clothes as described in Embodiment 1. The rapid inflation device 1 adopts a solid propellant rapid gas inflation device.

A rapid inflation device using solid propellant is installed in the opening of the air bag. The quick inflation device is connected to the trigger circuit by a wire, and the trigger circuit is powered by a battery, and the weightless state is judged by the connected gravity sensor. The trigger circuit judges whether the weightless state time of the gravity sensor is greater than 0.2 seconds, so as to determine whether to trigger the quick inflation device. The whole set has a small thickness and can be easily packed into the interlayer of clothes or trousers.

Embodiment 3. This embodiment is a further description of the airbag that can be installed in clothes as described in Embodiment 1. The airbag body 5 is made of rubber or nylon.

The airbag body of the present invention is made of rubber or nylon, and the two materials can be folded and placed in the interlayer of clothes for convenience and have small volume after folding.

Specific Embodiment 4. This embodiment is a practical method for an airbag that can be installed in clothes as described in Specific Embodiment 1. The specific steps of the method are:

Step 1. Fix the quick inflation device 1, the gravity sensor 2, the trigger circuit 3, the battery 4 and the airbag body 5 in the clothes;

Step 2, turn on the power switch of the trigger circuit 3, the trigger circuit 3 detects the weightlessness time of the gravity sensor 2 in real time, when the gravity sensor 2 detects that it is in the weightlessness state for more than 0.2 seconds, the trigger circuit 3 triggers the fast inflation device 1;

Step 3: The trigger circuit 3 triggers the rapid inflation device 1 to start inflating the airbag body 5 after being triggered by the trigger circuit 3 .

When the user installs the self-inflating airbag of the present invention in the clothing and falls on the road, if the falling distance is greater than 20 centimeters or 0.2 seconds, the trigger circuit will automatically trigger the fast inflation device to make the airbag start to inflate, and the airbag will start to inflate within 0.05 seconds. Inflation is completed within seconds. In this way, when the drop distance is about 30 cm, all the airbags have been inflated, which can effectively provide buffer protection for the key parts of the personnel's body. In this way, in winter in the north, especially for the elderly who walk outdoors, the probability of falls or even fractures can be greatly reduced.
