Description

Technical Field

[0001] The utility model relates to the field of anti-fall airbags for protecting human bodies, in particular to a protective airbag. Background Art

[0002] As the population continues to age, the safety of the elderly has attracted more and more attention from all walks of life. Falling is a common phenomenon among the elderly, which not only has a serious impact on the health of the elderly, but also brings huge psychological and economic pressure to the family. In order to solve this problem, airbag clothing came into being.

[0003] Airbag vests are a type of protective equipment designed specifically for the elderly. They are made of cloth or the latest technological fabrics and have a built-in inflation device. When an elderly person falls, the vest can be inflated instantly, effectively alleviating the impact of the fall and protecting the elderly person's safety to the greatest extent. In addition to being used outdoors, airbag vests can also be used at home to provide all-round protection for the elderly. For example, when the elderly are walking around at home, they can wear airbag vests. Once they fall, the vest can be inflated immediately to protect the elderly person's body.

[0004] However, during the inflation process of traditional airbags, the size and uneven layout of the internal structure of the airbag can easily lead to an uneven inflation process and large local pressure differences, resulting in local air shortage or local bulging within a unit of inflation time, which greatly affects the protective effect of the airbag. At the same time, traditional airbags have unilateral air intake and low air intake efficiency. Utility Model Content

[0024] Figure 3 It is a diagram of the air flow path in the airbag of the utility model. DETAILED DESCRIPTION

[0025] Combination Figure 1 As shown:

[0026] In this example: a protective airbag includes an airbag body 100 and an outer garment 200, wherein the airbag body 100 is disposed inside the outer garment 200.

[0027] Specifically, the airbag body 100 is arranged in the outer garment 200 by sewing, bonding or other means. Preferably, sewing is adopted, which has the effect of firm connection and is not easy to loosen and fall off, and the processing method is mature.

[0028] In this embodiment: the airbag body 100 includes an upper airbag 1, a middle airbag 2 and a lower airbag 3, and the upper airbag 1, the middle airbag 2 and the lower airbag 3 are connected from top to bottom in sequence and formed as one piece, the upper airbag 1 includes a left chamber 4, a right chamber 5, an upper chamber 6 and a central chamber 7, and the lower airbag 3 includes a lower chamber 8.

[0029] Specifically, the upper airbag 1, the middle airbag 2 and the lower airbag 3 are interconnected, so the internal left chamber 4, the right chamber 5, the upper chamber 6, the central chamber 7 and the lower chamber 8 are also interconnected, and when inflated, the gas circulates up and down inside.

[0030] In the present embodiment: an upper partition 9 is provided in the central chamber 7 , a middle partition 10 is provided in the middle airbag 2 , and a lower partition 11 is provided in the lower chamber 8 .

[0031] Specifically, the function of the partition is to guide the gas. When the gas flows inside the airbag, it is hindered by the partition and the gas will flow in the direction guided by the partition.

[0032] In this example: the ends of the left chamber 4, the right chamber 5, the upper chamber 6, the central chamber 7 and the lower chamber 8 are all designed to be arc-shaped.

[0033] Specifically, the arc-shaped design replaces the traditional right-angle design, and the gas flows more smoothly in the arc-shaped part. When inflating, the gas flows through the arc-shaped part, and it will turn and flow smoothly, making the inflation effect faster, thereby better ensuring human safety.

[0034] like Figure 2 As shown:

[0035] In this example, a left air inlet 16 and a right air inlet 17 are symmetrically provided at the left and right ends of the lower air bag 3 .

[0036] Specifically, the double air inlets replace the traditional single air inlet, which increases the inflation speed and better ensures human safety.

[0037] In this example: a left airflow channel 15 and a right airflow channel 16 that are symmetrical on both sides are formed between the middle partition 10 and the middle airbag 2, and the upper ends of the left airflow channel 15 and the right airflow channel 16 are connected to the upper airbag 1, and the lower ends of the left airflow channel 15 and the right airflow channel 16 are connected to the lower airbag 2.

[0038] In this example: the left chamber 4, the right chamber 5, the upper chamber 6 and the lower chamber 8 are symmetrically arranged with the middle partition 10 as the central axis.

[0039] In this example, there are a number of upper partitions 9, which are symmetrically arranged with the middle partition 10 as the central axis.

[0040] In this example: the number of the lower partitions 11 is several, and they are symmetrically arranged with the middle partition 10 as the central axis.

[0041] Specifically, the partitions and chambers are symmetrically arranged with the middle partition 10 as the central axis. When the gas flows inside for inflation, it can be inflated to various parts of the airbag evenly, synchronously, smoothly and quickly, so that various parts of the airbag will not be partially lacking in air or partially over-inflated, affecting the protective effect of the airbag.

[0042] In this example, a gas bottle chamber 13 symmetrically arranged on both sides is formed between the outer garment 200 and the airbag body 100, and the gas bottle chamber 13 is provided with a gas bottle 14, and the gas bottle 14 is connected to the corresponding air inlet.

[0043] Specifically, the inflation bottle 14 can be connected to the air inlet through a thread, or can be connected to the air inlet through a snap-fit ​​method, or can be connected to the air inlet through other forms; preferably, it is connected to the air inlet through a threaded connection method, which has the advantages of quick connection and good sealing effect after connection.

[0044] In this example, the upper partition 9, the middle partition 10 and the lower partition 11 are all filled with sealed and airtight materials.

[0045] Specifically, in order to produce a partition effect, the partition needs to adopt an airtight design, and an airtight filler such as rubber or other plastic materials can be used; a hollow design can be used, such as a partition that is hollowed out by using sealed cloth; preferably, an airtight filler, rubber, is used and sewn at the position of the airbag partition to produce a partition effect.

[0046] like Figure 3 As shown:

[0047] Flow direction inside the airbag: the left air inlet 16 and the right air inlet 17 intake air into the airbag, and the gas flows through the lower chamber, the left air flow channel and the right air flow channel at the same time. The gas flows to the left chamber 4, the right chamber 5, the upper chamber 6 and the central chamber 7 via the left air flow channel 14 and the right air flow channel 15; when the gas flows in the lower chamber, it is guided by the symmetrical lower partition 11, so that the gas fills the lower part evenly and quickly; when the gas flows in the left chamber 4, the right chamber 5, the upper chamber 6 and the central chamber 7, it is guided by the upper partition 9, so that the gas fills the upper part quickly and evenly; among them, the middle partition has the function of symmetrically draining the gas.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
