Description

Title of the Innovation

Headrest with spring-loaded window breaking system and emergency inflatable lifesaving buoy

Technical Field

The innovation is directed to a multipurpose headrest with spring-loaded window breaking system for quick and easy window glass breaking in an emergency. Headrest consists lifesaving buoy to assist escaped people to survive in a drawing situation. Therefore, this innovation is much related with the field of human safety.

Background art

Emergency escaping of sinking vehicles mostly become fatal due to limited time of escaping. Due to outside water pressure on the side door of a partially or fully submerge vehicle, an enormous force needs to open a door and escape the situation. Mostly all modern vehicle windows are powered and when water entered to vehicle circuits all shutdowns or malfunction immediately due to short circuit. Therefore, opening a window is not practical all the time. Therefore, escaping a sinking automobile become so fatal causes hundreds of passenger deaths per year all over the world.

Nowadays most of the glass breaking devices are a separate tool which has to keep near a place where passengers can quick access. Most passengers are not aware of the tools or location of the tools. In a disaster situation, tools may not be visible to a person who is not priory aware. One conventional method of glass breaking is using a headrest of the car and using its steel legs to smash the window until the window breaks. This method requires passenger's concentration, strength and it is time consuming. Since timing is the most crucial factor, a requirement of a fast and easy window breaking method is essential which can be easily used in a panicking situation.

Similar to sinking automobiles situation there are many situations which people need to break windows and escape. For an example escaping buildings in flooding situations, fire situation become so fatal where victims need to escape situation within limited time.

Although the people escape from the drowning vehicle or flooding buildings, inability to swim can be another deadly scenario that the people have to face. Therefore, necessary of a lifesaving buoy is essential to totally minimize drowning fatalities. Since time factor is crucial in above scenario, an easy and fast deployment of life saving buoy is essential.

Technical problem

1) In vehicle accidents specially fully or partially drowned cases, there are scenarios that the passengers get trapped due to inability to open any doors or windows

2) Most glass breaking devices are separate tools which has to keep near a quickly accessible place. In an emergency, the victims should know its location of the tools and the way of using it. But most of the situations victims are unaware of the tools and its usage. 3) Conventional headrest steel legs are used to break windows, but the procedure requires both the time and the strength which are very crucial and limited in an emergency.

4) Most victims (specially women and children) find it difficult to follow the conventional method of breaking glass using conventional headrests since they lack enough strength and concentration in an emergency.

5) Inability to swim is another threat to the victims' life in a drowning scenario.

6) In vehicle drowning situation, victims have a limited escape time. Thus, they need a proper method to break windows and escape. Therefore, the method needs to be easy to use and very responsive

7) In drowning scenario, victims need to have a method to be safe after escaping the drowning vehicle.

8) Since the lack of concentration in these situations, the method needs to be automated which is inflating the lifesaving buoy or jacket

9) When jacket is fully inflated, the passengers should have quick detachment method of life jacket from the headrest.

10) Most automobiles have standard headrest legs. Diameter of the legs and distance between the legs should have the same specifications in the production line.

11) Headrest spring loaded glass breaking system must not be visible to the outside and should not compromise the interior design safety of the people.

12) The carbon dioxide self-inflatable jacket inflating system which is in the headrest should not be visible to outside and the system deploy without the intention of the people.

Technical solution

This innovation addresses above issues by a use of multipurpose headrest with window breaking attachment and self-inflatable lifesaving buoy. The innovation provides a fast and easy to use window breaking mechanism attached to the headrest, so that victims can safely escape from the trapped situation such as drowning vehicle.

The innovation uses a spring-loaded spike impact method attached to the headrest which enables people to shatter the glass with a minimum effort. The mechanism is simplified such that it can be easily operated even by a child in an emergency. The compressed carbon dioxide based self-inflating lifesaving jacket provide an added safety to the people which address the drowning issue of the people. The whole system will limit the escaping time and safe the victims. Therefore, the innovation will save hundreds of people lives in an accident and specially in emergency drowning situations.

l. Innovation includes an easy, quick and reliable spring-loaded glass breaking attachment to break windows of trapped situation. When spike in headrest leg are pushed against the window, the spring will release with a huge force which will eventually break the window. 2. Innovation includes spring loaded glass breaking attachment in one leg of headrest. Since the system is in the headrest, all the victims will be aware about the location of the tool and due to the simplicity of the system, it will be very easy to use.

3. Innovation includes spring loaded glass breaking attachment. The passengers just have to push the spike side into the glass of the window without much effort. When spring fully pressed it will automatically trigger and it will an impact on the window which will create a small crack on window. No space needs to swing the headrest as so swinging of headrest is needed to break the glass

4. Breaking of windows can be done using the spring-loaded method less than one second and no special effort is required.

5. Compressed carbon dioxide based self-inflating lifesaving buoy provides required floating to be safe on water without drowning.

6. Innovation includes spring loaded glass breaking attachment which required less than one second shuttering a glass. System is easy and quick to use.

7. In sinking automobile situations, passengers have limited escape time and they should have access to a lifesaving method to survive in water within a small period of time.

8. Innovation include compress carbon dioxide self- inflatable life jacket which can be deployed by the pulling string on other leg of headrest which will not require any added effort. The life jacket will inflate within few seconds.

9. Sharp edge is available on the headrest to cut the string jacket when it needed to be separated from the headrest.

10. Innovative headrest with all glass breaking and lifesaving system has designs to fit in all standard headrests. Therefore, no car seat or headrest replacement is required.

11. Headrest spring loaded glass breaking system spike is located at the end of one leg which will not be visible to outside and will be located inside the hole of vehicle seat. Headrest compress carbon dioxide self-inflatable jacket inflating system is carefully integrated inside of headrest and it is not visible Thus, this will not compromise the interior design and the safety of the passengers.

12. The pulling string of jacket is kept at the end of headrest edge which goes inside the seat hole. Therefore, to deploy the jacket the user has to remove the headrest. This will minimize any accidental deployment of the lifesaving jacket.

Mode for innovation

In overview, the present invention consists of a headrest 1 including all automatic inflatable lifejacket inside the headrest and a spring-loaded glass breaking mechanism with spike 4 designed inside one side of the metal frame 5. On the other side of the steel frame 2 designed such that matching standard locking system and a plastic knob 3 to pull and deploy said lifesaving buoy inside the headrest 1 (See FIG.l). As depicted in thee FIG.2 present invention can easily integrate into standard seats 7 headrest position locking system 6 without any modification. In order to prevent misuse of lifejacket pulling knob 3 kept inside of the vehicle seat 7. Similarly, sharp spike 4 kept inside the holes of vehicle seat 7 avoiding injuries could happen by the spike.

As depicted in FIG.3A Inside the headrest 1 large cavity 10 has created in order to set up all the component of compressed carbon dioxide based self-inflatable life buoy system. The self- inflatable life buoy system consists of life jacket 18, a compressed carbon dioxide tank 11, carbon dioxide gas releasing mechanism 13. A string 14 connects carbon dioxide gas releasing mechanism 13 and pulling knob 3. The string runs through an angle hole 16 and steel hollow frame 2 with locking notches 9. A spring-loaded glass breaking system 5 has designed inside the other side of the steel frame 12 with the sharp spike 4. FIG.3B, FIG.3C shows the more detail view of the arrangement of components inside the headrest 1. The C0₂ releasing mechanism 13 has hardly connected to steel frame 12 using newly designed locking plastic part 17 (see FIG.3D, FIG 6A). The steel frame partially submerges inside the sponge of headrest 1 in order to gain strength of the headrest and frame. When a user pulled knob 3 in the direction of the arrow in FIG.3C the string 14 will pull the sliding linear cam 45 of C0₂ gas releasing mechanism 13. When cam 45 slide through the releasing mechanism the sharp end 47 of punching pin 46 will be push into the C0₂ cartridge 11 by tapered surface 52 of sliding cam 45 (See FIG.6D, FIG.6F, FIG.6G). Thus, as depicted in FIG.6C, gas releasing mechanism 13 create a hole inside C0₂ cartridge 11. When C0₂ cartridge punched pressurized gas will discharge through hole 49 into the life buoy 18 which connected to hole 48. Once full 33g of compressed C0₂ release into life jacket with standard atmospheric pressure life jacket will have 15 liters of volume. This volume gives around 15kg (150 N) of extra buoyancy in water with lg/cm³ density.

In a sinking automobile situation in order to deploy a lifesaving jacket or buoy user need to get headrest out from the seat and pull knob 3. Once knob 3 is pulled away from headrest as described above life jacket will automatically inflate with 151 of volume. The light sewing around the headrest cloth created such that it closes all component with safely and tidy. When lifejacket inflated due to the extra pressure inside the headrest sewing tears and let inflated life jacket come out (FIG.7B). Just after life jacket fully deployed (FIG.7A), user need to separate it from the headrest 1. In the steel frame, an angle hole 16 has created to cut pulling string 14 out from frame 2 as depicted in FIG.5C. Due to the angel of cutting hole 16, it has created two edges one side sharp edge with small cutting angle 44, another side edge with large cutting angle 43 (FIG.5A). When user pulling string 14 via knob 3 the string will move on top of large cutting angel 43 without damaging the string. Once the life buoy deployed user will pull life buoy out from the headrest. Thereby first, it releases from plastic locking system 17 which connect to steel frame 12 with plastic circular lock 50 (FIG.6A). Once string stretch enough on top of the sharp cutting angle 44 string will damage and cut from the attachment.

In an emergency situation when a user pushes steel spike 4 toward the window, the glass breaking system will undergo four consecutive stages as depicted in FIG.4A, FIG.4B, FIG.4C, and FIG.4D.Once the system reaches final stage automatic hammered spike will make a small hole or crack in the tempered glass in order to shatter the glass. As shown in FIG.4A glass breaking attachment consist of steel punch plunger (spike) 4 with sharp tip 8 which hold by metal punch holder guide 22 which has bore with the same diameter of the plunger. Inside metal case 21 which connect with punch holder 22, with internal thread 23 a metal tumbler 26 placed associate with spring 29. The system is called in relax stage where the stem 31 of plunger 4 is situated off the alignment with the hole of hammer 27 as depicted in FIG.4A. The stem 31 diameter has created such a way that it can go inside of the hammer 27 hole.

In order to initiate the loading stage depicted as FIG.4B, the tumbler stem 31 must unalignment with hammer hole 34. When the pressure applied on body 20 punch plunger 4 push into the body 22 and push tumbler 26 with associated spring 29. When the tumbler spring 29 compressed on top of the angled face due to the angled face of tumbler 35 onside of the spring compress more compare to the other side. Thus, it creates two unequal forces along with both sides of the tumbler longitudinal axis. This creates a non-equilibrium rotational torque around the tumbler lateral axis with longitudinal force. Due to this non equilibrium rotational torque, the tumbler will rotate along the lateral axis of it. Therefore, tumble will be off alignment with longitudinal axis all the time when pressure exists. In order to increase the unalignment, along cutting groove 19 has created in tumbler stem 31. As depicted FIG.4J the conventional tumbler without improvement creates less unalignment from the center axis of the system due to the absence of proper rotational torque. As depicted in the FIG.4H system with new tumbler create more unalignment from center axis due to the rotational torque (as depicted by the circular arrow) create from tumbler angle face and spring. Thus, these two new improvements on tumbler will increase the consistency of successful loading stage after each relax stage of the system which is a must for a safety equipment.

In this loading stage, the tumbler 26 push hammer through hole with cornicle neck 28 designed inside the body 21. Due to nonalignment of stem 31 (illustrated on location 33) with hammer hole 34 (See FIG.4B). The hammer spring 30 will compress by hammer 27 when plunger push into inside. This creates an increasingly strong force on hammer 27. When spike 4 pushed into maximum and system will arrive at the stage as illustrated in FIG.4C. When tumbler 26 move inward due to the conical shape 36 on tumbler and middle tubular body 28 the thin stem will align with hammer hole 34. When tumbler stem 31 and hammer hole 34 perfectly aligned as depicted in location 37 that stage called the firing stage. Just after system arrived firing stage due to the strong force created on compressed hammer spring 30 hammer 27 will instantly move on the stem 31 of tumbler 26 and impact on location 38 creating huge impulse force. This impulse force transfers to plunger 4 through tumbler 26 and then into window 40 via sharp tip 8. Due to this huge impulse force created on tip of plunger 8 and window 40 small cracks or a hole will be created top of the tempered or non-tempered glass. This stage called breaking stage and it has depicted on FIG.4D. As a result of this crack, the glass will instantly shatter into pieces creating an escape window for trapped people.

Advantageous effect

Innovation includes an easy, quick and reliable spring-loaded glass breaking attachment to break windows of a trapped situation. The use of this method more convenient compare to breaking a window with conventional methods. When headrest spring loaded spike push into the window once it fully pressed it will automatically impact with window to break. The heavy impact of the spike will make a small crack of the window which will shatter tempered or non- tempered glasses creating space to escape. Most present glass breaking devices are separate tool which has to keep near a place where victims can quick access. In a disaster situation, all victims should know its location kept by tool owner of the tool and how to use it. As disaster happen unintentionally most victims don't aware about glass breaking tool location neither how to use. Due to innovation includes spring-loaded glass braking system in one leg of headrest all victims are well known about the location of glass breaking system. As the system is very easy to use and straightforward any victims will know how to utilize.

If a victim faced a sinking automobile situation passenger need to break the window and escape into the water. In a similar situation, the self-inflatable lifesaving buoy system which includes in present innovation will be used as a lifesaving assistance to survive in water. As present innovation includes glass breaking system and a lifesaving system inside a headrest free space without affecting passenger comfortability or vehicle interior appearance present innovation is to save thousands of lives in automobile fatal disaster situations.

Industrial applicability

Present innovation applicable mostly in the area of human safety and risk management. Innovation can be used in any industries which use headrests as a comport element and innovation add extra safety features to those products. Innovation can majorly use in industries especially in the transport industry with Automobile industries, Cursing industry and Aircraft industries. In any case of accidents happen in those industry fields victims can use the innovation to escape an appropriate situation. Due to the arising natural disasters such as floods, Tsunami, storm, forest fires and accidental incidents such as electrical fires, gas fires happening inside building innovation even can introduce to modern seats which use inside any building to use as an emergency safety tool.
