Abstract

An auxiliary airbag swimsuit, comprising: a reinforced swimsuit, a trigger means, one or more airbags, and one or more inflation means. The reinforced swimsuit has enough strength to bear pulling caused by the airbags during floating, and allows floating on water for a long time; when the trigger means is activated, the inflation means inflates the airbag; after being inflated, the airbag has an enough floating force to support and balance a user, so that the mouth and nose of the user can come above the water surface. By utilizing the auxiliary airbag principles, automatic drowning protection is implemented.

Description

Auxiliary airbag swimsuit

Field of invention

The invention relates to an auxiliary airbag swimsuit, in particular to a swimsuit that realizes automatic drowning protection by using the principle of an auxiliary airbag.

Background technique

Air-bag (or Supplementary Restraint System, hereinafter referred to as SRS) refers to an inflatable soft bag installed in a car, which is used to pop out at the moment of a collision accident of the car, so as to buffer and protect the safety of the driver and passengers. Generally, it can prevent the head and body of the occupant from directly hitting the interior of the vehicle, reducing the degree of injury to the occupant.

The principle of SRS is: when the sensor detects a collision, the control system will determine the degree of the collision to determine whether to trigger the inflator, usually a gas generating agent such as explosives and an ignition device to form an inflatable module. Because the impact process time is very short, usually the airbag is about 25 to 35 milliseconds from triggering to completion of the inflation process. If the inflation time is too long, the protection effect will be lost.

There are some products on the market that use the principle of SRS to protect personnel and reduce the degree of injury:

·Drowning rescue bracelet: triggered in the water, the built-in soft capsule of the bracelet pops up as a buoyancy device;

·Fall life-saving collar: the acceleration sensor is triggered, and the soft capsule pops up as a protective cap when the user falls;

·Drowning life-saving collar: triggered by water pressure or user, the built-in soft capsule pops up to become a neck life-buoy;

For drowning protection, because the airbag popped by the bracelet is far away from the user’s nose and mouth when floating in the water, its use scenarios are mainly diving. For marine lifesaving, such airbags are only small and convenient to carry around. Not as comfortable and labor-saving as a life jacket. While diving, if an accident occurs, it may be due to panic that the user has choked a lot of water and became unconscious when he floated to the surface, and he could not actively use the airbag to bring his nose and mouth out of the water. This reduces the rescue power.

As for the life-saving collar, because the life-buoy is wrapped around the neck, accidents may occur. Moreover, it is not as comfortable as a life jacket. If it is used for life saving at sea, floating through the neck for a long time will also damage the cervical spine.

Summary of the invention

Users need more safe, comfortable and labor-saving life-saving devices. It is conceivable that the airbag is built into the swimsuit and appropriately thickened and reinforced for safety. Triggered by water pressure and a timer, when the user’s nose and mouth are immersed in water and the water pressure at the corresponding swimsuit position continues for a certain period of time, inflation is triggered, or the user manually triggers, forming an airbag on the user’s shoulders, so that when the user emerges Its nose and mouth are above the water, reducing the risk of diving accidents. You can also adjust the size of the front and rear airbags to increase comfort and ensure that the face floats diagonally upwards.

However, it should be understood that the content of the present invention may not include all aspects and embodiments of the present invention. The content of the present invention is not meant to be restricted or restricted in any way, and the present invention disclosed herein will be understood by one of the following: The technical staff includes obvious improvements and modifications.

Detailed ways

The present invention will now be described more fully hereinafter. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Hopefully, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

It should be understood that various changes can be made to the function and arrangement of elements without departing from the spirit and scope set forth in the appended claims. Therefore, the embodiments are examples or implementations of the present invention, rather than the only implementations. The various appearances of "one embodiment," "an embodiment," or "some embodiments" do not necessarily all refer to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may also be provided individually or in any suitable combination. Conversely, although the invention may be described herein in the context of separate embodiments for the sake of clarity, the invention may also be implemented in a single embodiment or any combination of embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of related technologies and the present disclosure, and will not be interpreted as idealized or excessive The formal meaning, unless explicitly defined as such in this article.

Supplementary Restraint System (hereinafter referred to as SRS) in order to inflate at a high speed, its inflator usually uses explosions, such as sodium azide (NaN ₃ ) or ammonium nitrate and other chemicals, which are quickly decomposed by violent impact and produce a large amount of gas. The airbag is inflated. But there are other principles of SRS, such as motorcycle and electric car SRS jackets and vests, which use a sleeve containing compressed gas as an inflator. This system requires 100-300 milliseconds to inflate, which is much slower than car auxiliary airbags. However, unlike the small space in the car, motorcycle and electric bike SRS jackets and vests are used to start and inflate when the rider leaves the motorcycle or electric bike due to an impact or fall, and has ample response time. For drowning protection, 0.3" is not a problem at all, and the compressed gas sleeve is too bulky for a swimsuit.

However, the embodiments of the present invention are not limited to chemical explosion type inflatable devices. For example, a swimsuit connected to a compressed gas sleeve on a lifeboat may also use the airbag swimsuit included in the embodiment of the present invention. The trigger device is a starting rope, and when the user falls into the water, the internal air bag of the swimsuit can be inflated.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications according to the claims and specification of the present disclosure are still within the scope of the claimed invention. In addition, each embodiment and claims may not include all the advantages or characteristics disclosed.
