Autonomous, multifunctional emergency breathing air system for vehicles and personal protective equipment

Abstract

Emergency breathing air system for vehicles and watercraft, comprising a flexible breathing air reservoir with connections for breathing hoses, characterized in that the reservoir has at least two Y-shaped hose connections for the simultaneous supply of at least two persons, at least one sensor for automatic activation upon water ingress or submersion, a device for drawing in and storing air from the interior or the environment, a fluorescent coating at least of the air reservoir and the hoses, and at least one optical and / or acoustic signaling device to facilitate rescue.

Description

1. Technical field

[0001] The system is an autonomous emergency breathing air system designed for short-term use in vehicle sinkings, water emergencies, and personal protection situations. It serves to provide breathable air to vehicle occupants or individuals in contact with water, thereby increasing their chances of survival and facilitating evacuation. 2. State of the art

[0002] Currently, systems such as automatic window openers (AWOS) and air cylinders for emergency situations are known. However, there is no standard integrated system that automatically stores cabin air or ambient air in the event of water ingress and simultaneously makes it available for two people. Similarly, fluorescent markings or acoustic signals are not yet commonplace. 3. Object of the invention

[0003] The aim is to provide a compact, robust and versatile system that automatically or manually draws in and stores air upon water ingress and provides respiratory assistance for at least two people via flexible Y-branching breathing tubes and fluorescent and acoustic signaling devices. 4. Solution to the task

[0004] The problem is solved by providing an autonomous emergency breathing air system that activates automatically or manually upon contact with water. The system includes a compact air reservoir with sensors to detect water or pressure changes, a quick-release valve for drawing air from the vehicle interior or the surrounding environment, and flexible breathing tubes with a Y-connector for simultaneously supplying at least two people. Fluorescent coatings and audible or visual signaling devices are provided for improved visibility. The entire system is shockproof, waterproof, and suitable for installation in vehicles or integration into personal protective equipment. 5. Advantages of the invention - Rapid automatic or manual air supply upon contact with water - Providing for at least two people for 2-3 minutes - Versatile installation options in vehicles or portable in personal protective equipment - Increased visibility through fluorescent coating and acoustic signals - Compact rolling version with automatic unfolding - Robustness and easy maintenance 6. Areas of application - Motor vehicles of all types (cars, trucks, buses, motorcycles) - Watercraft (boats, rafts, ships) - Personal safety equipment (life jackets, safety jackets) - Other areas of application with a risk of water contact 7. Technical verification

[0005] The average air volume in a vehicle interior is approximately 4500 liters. During stressful situations, two people require about 12-18 liters per minute. This equates to a need for approximately 90 liters of air over 2-3 minutes. The bottle is designed to draw in and store this air within seconds.

Claims

[1] Emergency breathing air system for vehicles and watercraft, comprising a flexible breathing air reservoir with connections for breathing hoses, characterized by that the storage unit has at least two Y-shaped hose connections for the simultaneous supply of at least two persons, at least one sensor for automatic activation upon water ingress or submersion, a device for drawing in and storing air from the interior or the environment, a fluorescent coating at least of the air storage unit and the hoses, and at least one optical and / or acoustic signaling device to facilitate rescue.
