The invention relates to a human body protection device, more particularly to a safety airbag for human body protection, which can provide protection when a human body falls down.
The technology of automobile airbag has been highly developed. The safety airbag is mainly composed of a sensor, a microprocessor, a gas generator, an airbag and the like. The sensor and microprocessor are used for determining the degree of collision, transmitting and sending signals. The gas generator ignites according to the signal indication, and the solid fuel is combusted to generate gas, such that the airbag is inflated rapidly. Meanwhile, the airbag is provided with a safety valve, when the airbag is overinflated or the pressure inside the airbag is greater than a certain value, some gas will be discharged automatically, thereby avoiding the damage to a person inside the vehicle due to crushing.
From the people-oriented view, accidental falling may cause damage to old people due to the weak body function, low physical quality and hip muscle atrophy. In severe cases, evenly it may be life-threatening. For the elderly people capable of disposing, if the electric induction device can determine the falling accidents within a few milliseconds at the moment of falling to the ground, the sensor commands the airbag to be opened by the electronic control device, and the inflated airbag can provide buffer protection for the worker's body, especially for loose bones and joints, thereby reducing the impact of falling on the elderly.
Generally the automobile airbag must be used with the safety belt; otherwise, the detonation of airbag will cause secondary damage to the driver and passenger. The automobile airbag is currently a passive device for safety protection on the cars, and can only be opened when an impact occurs.
The airbag device for human protection in prior art also has an airbag helmet. Compared with the ordinary helmet, the airbag is softer than the lining of the helmet and can absorb more impact force, but in use, it only can provide protection for the neck and head, and the other parts of the person are not protected. Thus, the protection area is small. When the user falls down, the other parts of the body such as the waist, the legs and the hips are subject to injury. Therefore, it is needed to develop an airbag protection device that is simple in structure, convenient for folding, and meet the theory of ergonomics.
An object of the present invention is to overcome the above deficiencies in the prior art, and provide a safety airbag for human body protection, which can comprehensively protect a human body and improve the safety of daily activities of the elderly people.
In order to solve the above technical problems, the present invention provides a safety airbag for human body protection, including an upper airbag and a lower airbag, which provide protection for an upper part and a lower part of the human body respectively. The upper airbag includes a back airbag and a head airbag laterally extending from a top of the back airbag, such that the upper part of body such as a back, a neck and a head can be protected fully. The upper airbag is T-shaped after folding. The lower airbag includes a waist airbag and a hip airbag extending downward from the waist airbag to a knee. The waist airbag can be folded and the hip airbag can be wound towards the waist airbag, such that the waist airbag is superimposed on the hip airbag. The lower airbag has a waistband shape after folding. The safety airbag after folding occupies a small space, and is conveniently used in combination with a belt, a strap, and the like, and does not affect the daily appearance. A fixing band is provided at each side of a lower end of the hip airbag. The free ends of the fixing bands are connected with each other by a snap. After the lower airbag is unfolded, the waist airbag is fitted to protect the waist. The hip airbag surrounds the hips and the legs under the action of the fixing bands, to protect the rear side and two sides of the hips and the legs. The upper air inlet and the lower air inlet are in fluid communication with each other, and the upper airbag and the lower airbag can be inflated simultaneously. When working, the upper and lower airbags are simultaneously opened to protect the human body comprehensively.
Preferably, the back airbag is folded along a center line thereof. The head airbag is wound towards the back airbag, and the wound head airbag is folded towards the back airbag until the head airbag is completely folded in the length direction, so that the upper airbag is folded as an elongated structure, which is provided on the back of the human body, and thus the beauty of wearing of the human body will not be affected. Meanwhile, it is convenient to quickly open an upper storage device, thereby achieving rapid opening and protection of the human body.
Preferably, the inflation device is further connected with a trigger button and a gravity sensor. An inflating device is opened automatically after receiving a falling signal from the gravity sensor, or the inflating device is manually activated by means of the trigger button when a human body feels that falling is coming, thereby ensuring the safety airbag can be opened in various ways before damage is made to the human body.
Preferably, the head airbag has a thickness of 40-80 mm after inflation. The back airbag has a thickness of 80-100 mm, a length of 500-800 mm, and a width of 350-500 mm after inflation. The waist airbag and the hip airbag have a thickness of 40-80 mm after inflation. Thus, sufficient cushioning is provided, and the protection effect is ensured.
Preferably, the head airbag is U-shaped, and the head can be surrounded and protected completely.
Preferably, the length of the waist airbag is less than the length of the hip airbag, so that the hip airbag protects the legs as much as possible.
Preferably, the waist airbag has an arc-shaped structure fitted to the human body, and the hip airbag includes a plurality of columnar airbags, so that the lower airbag forms a skirt structure after inflation, thereby expanding the protection range of the lower body.
Preferably, at least one upper air inlet and at least one lower air inlet are provided, and the upper airbag and the lower airbag can be simultaneously inflated.
Preferably, two upper air inlets and two lower air inlets are provided, so that the inflation devices are arranged conveniently, and the inflation devices are located at two sides of the two upper air inlets and the two lower air inlets respectively.
The safety airbag for human body protection of the invention can comprehensively protect the human body and improve the safety of the daily activities of the elderly people.
The invention will be further illustrated in more detail with reference to the accompanying drawings and embodiments. It is noted that, the following embodiments only are intended for purposes of illustration, but are not intended to limit the scope of the present invention.
