Description

Protection system to protect a person Description:

The invention relates to a protection system for protecting a person with at least one inflatable airbag.

In order to protect people during different activities, for example when cycling, skiing or horse riding, safety systems are known that have an inflatable airbag. Various methods are known from the prior art for inflating the airbag. On the one hand, high-pressure cartridges filled with gas with a pressure of around 200 to 300 bar are used, and on the other hand, techniques are known that drive a turbine (hair dryer system) driven by batteries or capacitors, which fills the airbag with ambient air. Systems filled by high pressure cartridges are the most common on the market due to their low price. However, both cartridge systems and electric hair dryer systems (blower systems) have significant disadvantages.

Cartridge systems are limited to one-time use because the weight of a second cartridge would be too high. The high-pressure cartridges used in previous systems are configured to only contain sufficient volume for a single use and therefore must be completely replaced to make the system operational again close. Therefore, if a user accidentally triggers the system, it cannot be "loaded" again without replacing the high pressure cartridge.

Furthermore, previous systems contain one or more flammable or pressurized components that are not permitted in aircraft and helicopters, which severely restricts the use of the systems when traveling. Electric hair dryer or blower systems have the disadvantage that they are very expensive and significantly heavier than cartridge systems due to the components used.

The object of the present invention is therefore to provide a security system which eliminates the disadvantages described above.

This task is solved by a protection system to protect a person with a. at least one inflatable airbag, b. at least one pressure chamber that can be filled with a gas, in particular air, in particular several times, c. at least one shut-off element arranged between the at least one airbag and the at least one pressure chamber, i.e. a triggering device which cooperates with the shut-off device to open the shut-off device, so that when the shut-off device is open, gas flows from the at least one pressure chamber into the at least one airbag, the triggering device comprising at least one sensor and/or a coupling element which can be coupled at least indirectly to a means of locomotion is.

The protection system according to the invention is therefore cartridgeless and fanless. This results in major weight savings. In addition, the system is less error-prone than known systems. The system can be used multiple times if the pressure chamber is refillable. No components need to be replaced to make the system operational again. It is also conceivable to replace the pressure chamber from time to time or after it has been emptied, i.e. to fill it only once.

The system can be designed to function without electricity. The pressure chamber is preferably suitable for receiving gases at a pressure >200 bar, in particular at pressures in the range 200-300 bar, preferably in the range 250-300 bar. The pressure chamber preferably has a filling opening that can be closed, in particular by an inlet valve. An external gas source, for example a compressed air source, can thus be connected to the pressure chamber in order to fill the pressure chamber with pressurized gas, in particular air.

The term “pressure chamber” expresses that the pressure chamber is suitable for receiving gases that have a pressure well above 1 bar, in particular well above 200 bar. A hand pump can also be connected to the pressure chamber in order to inflate the pressure chamber and store gases under pressure in the pressure chamber. Furthermore, it is conceivable to temporarily connect cartridges to the pressure chamber in order to fill the pressure chamber.

Several pressure chambers can be provided, which are connected to an airbag. Multiple airbags can also be provided. One or more pressure chambers can be connected to each airbag. It is also conceivable that a pressure chamber is provided to inflate several airbags.

Several shut-off devices can be provided between a pressure chamber and an airbag. If all shut-off devices are opened at the same time, the airbag can be filled particularly quickly. A shut-off device can be designed, for example, as a check valve. Several separate pressure chambers can be provided. Several pressure chambers can be provided that are connected to one another. A means of transport within the meaning of the invention can be, for example, a two-wheeler, in particular a bicycle, a scooter or a motorcycle. A horse also represents a means of transportation within the meaning of the invention. An indirect coupling to a means of transportation can occur, for example, by connecting the coupling element to a saddle of a horse. If the user of the protection system falls from the horse, the protection system is triggered when the coupling element is coupled to the saddle.

The at least one sensor can be designed as a crash sensor. In particular, the sensor can be designed as a speed sensor, acceleration sensor, G-force sensor, yaw rate sensor or the like. The sensor is set up to signal an event that should lead to the airbag being filled. Furthermore, it can be provided that more than one sensor, in particular two sensors, are provided that communicate with one another. For example, a sensor may be located on the user, for example in or on the user's item of clothing, a backpack, or a watch. This sensor can analyze the user's movement in real time, such as the user's position and speed. The sensor can be set up to detect falls. Another sensor can be located, for example, on a means of transport, such as a bicycle, and can detect vibrations. For example, if there is no shock from a cyclist but movement is still detected, a fall can be detected and the airbag can be triggered. However, if the second sensor detects a shock, for example because a cyclist hits an obstacle, the sensor on the user or an evaluation unit connected to the sensor can decide whether it is necessary to trigger the airbag.

The sensor or sensors can be connected to the protection system in a wired or wireless manner. The sensor can be arranged on the actual protective system containing the airbag, e.g. B. in or on a backpack. Alternatively, especially with wireless coupling, it can be arranged externally, e.g. B. on a means of transport, in particular a two-wheeler. Furthermore, the sensor can be attached to an object that is carried by a user. For example, the sensor can be arranged on a watch, a bicycle helmet or the like.

The protection system can have an emergency call function. For this purpose, the protection system can have a mobile radio module or can be coupled to a mobile phone so that a preset emergency number is called when the airbag is triggered. This call can be triggered with a time delay. For example, the call can only be made if the emergency call function is not switched off by the user within a predetermined time.

The protective system can be designed as a backpack or vest. This has the advantage that the airbag can be arranged particularly close to the body, in particular torso, of a user, so that when the airbag is triggered, the user, in particular torso and limbs, can be optimally protected by the airbag. One or more airbags can be arranged and configured in such a way that the head and/or the torso are protected when the airbag or airbags are inflated.

Airbags or airbag sections can be arranged in the shoulder and/or chest area of a user in the deflated state. Shoulder straps or shoulder sections with airbag sections can be provided. The shoulder straps can be connected to one another without leaving a gap in the chest area of a user. This means that the shoulder straps in the chest area are directly connected to one another over a certain length, so that the airbags or airbag sections arranged in the shoulder straps are deployed in the front neck area of a user. Furthermore, an airbag or airbag sections can be arranged in a hip belt.

Particular advantages arise when neck and shoulder sections are provided which have airbags or airbag sections (parts of an airbag) and the Wrap around the user's neck. This provides good protection for the particularly vulnerable neck/head area of a user.

The airbag or airbags are preferably arranged protected by a cover when they are not inflated. The cover has predetermined tear points or predetermined opening points that can be opened by the airbag or airbags when this or these is or are being filled with air.

Particular advantages arise when at least one pressure chamber is designed as a pressure hose. A pressure hose can have an inner diameter in the range of 5 to 11 mm, preferably in the range of 6 to 10 mm. If a pressure chamber is designed as a pressure hose, it can be arranged in a particularly space-saving manner. In addition, such a pressure chamber is particularly light.

A pressure hose can be made of plastic, in particular Teflon, or rubber and have a coating. Such a hose is particularly suitable for storing gases at pressures above 200 bar.

The filled pressure chamber, in particular the filled pressure hose, can preferably be bent manually if it is filled with a gas at a pressure >200 bar. This means that the filled pressure hose, for example in a protector, cannot be laid in a straight line, but in a curved shape.

The pressure chamber, in particular the pressure hose, can be constructed in multiple layers, with the outermost layer being at least partially braid-free and/or fiber-free. This can prevent leaks when the pressure hose is connected to other components.

The pressure chamber, in particular the pressure hose, can have an elastomer core that is surrounded by a reinforcing jacket. The (Reinforcement) casing can have one, two or more layers. The (reinforcement) jacket stiffens the pressure hose.

The (reinforcement) coating of the pressure hose can have metal, in particular stainless steel, carbon, aramid and/or plastic. Furthermore, the sheathing can be designed as a helix, braid or fabric. Preferably, the casing is designed to be flexible so that the pressure hose can be suitably arranged on the protective system.

It is particularly advantageous if the elastomer core has a smooth inner wall, in particular if it is not corrugated or grooved.

At least one pressure chamber can be protected by a cover. Such a protective cover can ensure the functioning of the protection system. In particular, such a cover provides protection against mechanical damage to the pressure chamber.

At least one pressure chamber can be arranged in or on a protector, in particular a back protector. The protector can represent the protective cover for the pressure chamber. Most backpacks for winter sports have a protector anyway. Due to their function, protectors have a high level of stability and are therefore particularly suitable for protecting pressure chambers. A (back) protector is therefore ideal for integrating a pressure chamber. Several separate pressure chambers can also be provided in one protector. Such a protector also provides padding and prevents the filled, hard pressure chambers from coming into direct contact with the user's back. In particular, protector material can be arranged between the pressure chambers and the back of a user.

A protector can have two half-shells, whereby the pressure hose or hoses can be arranged between the half-shells. In the protector Recesses can be provided in which one or more pressure hoses are inserted. The pressure hoses can be detachably arranged in the recesses. The protector can be removed from the protection system. The pressure hose or hoses can be arranged in a meandering, circular or spiral shape in or on the protector. If the protector has the pressure tubes, additional protection and padding are created. The arrangement of the pressure hoses in the protector is also particularly space-saving.

The protector can have side areas in which the pressure hose(s) is/are arranged. In addition, the pressure hose or pressure hoses can be arranged in a back part of the protector. This means there is plenty of storage space for the pressure hoses and a corresponding amount of gas can be stored.

At least one Venturi nozzle communicating with the ambient air of the airbag can be provided between the pressure chamber(s) and the at least one airbag. The Venturi nozzle can ensure that ambient air can also be directed into the airbag. It supports the inflation of the airbag. The Venturi nozzle can be arranged in the flow direction before or after a shut-off device. A shut-off device, in particular a check valve, and a Venturi nozzle can be designed as one component.

One or more couplings, in particular hose couplings, can be provided for connecting the airbag or airbags to the pressure chamber or chambers. As a result, for example, a protector can have pressure chambers that can be decoupled from the airbag or airbags so that the protector can be removed. A shut-off device and/or a Venturi nozzle can be arranged before or after such a coupling.

In particular, they can be provided on the airbag side or on the pressure chamber side.

Particular advantages arise when the protection system has a base part with a carrying system, with a piece of luggage being detachably attached to the base part and the at least one pressure chamber and the at least one airbag are arranged on the base part or on the luggage part. If, for example, the airbag and pressure chamber are arranged on the base part, the base part can be coupled to different luggage items, in particular luggage items of different sizes. If the airbag and pressure chamber are arranged in the luggage part, the base part can also be used with another luggage part that does not have a pressure chamber and no airbag if no special protection of the user is necessary.

In order to make it easier for rescue workers to access a user in an emergency, it can be provided that a pumping device is provided through which air can be quickly removed from the airbag.

Fig. 1 shows a user wearing a protection system 10. The protection system according to the invention is thus set up to be worn on the body by a user. The protection system 10 includes an airbag 12, which is shown here in an inflated state. The airbag 12 is configured in such a way that both a head area and a neck area as well as essential parts of the torso including the arms are largely surrounded and thus protected by the airbag 12. Optionally, a facial area 14 is excluded in the exemplary embodiment shown. The airbag 12 is arranged here on a backpack, not shown. The backpack is carried by the user via a carrying system 16, of which shoulder straps 18, 20 and a hip belt 22 can be seen here.

Fig. 2 shows part of a protection system 100, which is designed as a backpack. The protective system 100 has shoulder straps 102, 104, with a cover 110 being provided in shoulder sections 106, 108, which also extend into the neck area, in particular behind the neck of a user, at which predetermined tear points 112, 114 are provided. In the exemplary embodiment shown, the predetermined tear points 112, 114 are designed as zippers that are intended to burst open when an underlying airbag or airbag section is inflated. So that the predetermined tear points 112, 114 do not open unintentionally, protective tabs 116, 118 are provided, which can have Velcro fasteners.

A sensor 120, which is part of a triggering device, is also arranged on the shoulder strap 102. The triggering device continues to point an activation cable 122, which is connected to one or more shut-off devices which are arranged between the airbag or airbags and one or more pressure chambers.

In the embodiment of the protection system 200 according to FIG. 3, shoulder straps 202, 204 are also provided, which are connected to one another without gaps in a section 205. This means that airbags or airbag sections that are arranged on the shoulder straps 202, 204 spread out in the user's chest area and can therefore protect the torso particularly well. The shoulder straps 202, 204 merge into neck-shoulder sections 206, 208, which also have one or more airbags or airbag sections. Thus, as in the previous exemplary embodiment, the neck and shoulder area of a user is particularly well protected. The carrying system of the protection system 200 also has a hip belt 210, which also has an airbag, several airbags or airbag sections under burstable covers.

In the embodiment of a protection system 300 according to FIG. 4, the shoulder straps 302, 304 are connected to one another without gaps in section 305. Section 305 extends almost the entire length of a user's torso. The shoulder straps 302, 304, but also the shoulder straps 202, 204, are detachably connected to one another in sections 305 and 205, respectively. In particular, they are connected to each other via a zipper. The protective system 300 of FIG. 4 also has neck-shoulder sections 306, 308, which can be viewed as part of the shoulder straps 303, 304 and which enclose the neck of a user. Airbags or airbag sections are provided under appropriate covers.

The protection system 300 of FIG. 4 also has a hip belt 310 which has one or more airbags or airbag sections. The neck and shoulder sections 306, 308 also have one or more airbags or airbag sections. A variant of the protection system 300 is shown in FIG. The difference from FIG. 4 is that the shoulder straps 302, 304 are essentially the same width over their length and do not expand in width, as shown in FIG. 4.

Fig. 6 shows a protection system 400, which is designed as a vest. The vest has covers 402, 404 in its front area, which have predetermined tear points 406, 408. One or more airbags or airbag sections are arranged under the covers 402, 404. Protective tabs 410, 412 are provided for additional protection of the predetermined tear points 406, 408. The predetermined tear points 406, 408 can be closed by zippers. It can be seen that the covers 402, 404 and thus the airbags or airbag sections arranged underneath extend into a user's neck and shoulder area.

Fig. 7 shows a pressure chamber 30, which is designed as a pressure hose. The pressure chamber 30 has a filling opening 32 to which an inlet valve 34 is connected. An external gas source, such as a gas cartridge or a pump, can be connected to the inlet valve 34. The compressed air chamber 30 shown is designed in a meandering shape. It has several hose couplings 36, via which the pressure chamber 30 can be connected to one or more airbags. This allows the pressure chamber 30 to be separated from the airbag and removed from a backpack, for example. In the area of the hose couplings 36, shut-off devices can be provided, for example check valves. In addition, Venturi nozzles can be provided, which can enable an airbag to be filled with ambient air. Basically, only one shut-off device is necessary. However, several shut-off devices can be provided. Several Venturi nozzles can also be provided. Shut-off device and Venturi nozzle can be combined in one component. They can also be integrated in a hose coupling. Hose couplings are not mandatory. Particularly not if it is not intended to separate the airbag from the pressure chamber 30 and reconnect it. In the exemplary embodiment shown, the pressure chamber 30 is arranged protected by a cover 40. The cover 40 is designed as a protector 42.

8 shows a section of a pressure hose 50, as it forms the pressure chamber 30, for example. The pressure hose 50 has an inner jacket, for example made of plastic, in particular Teflon. The inner jacket 52 is surrounded by a casing 54, which can comprise stainless steel, plastic and/or carbon. The casing 54 is resistant to high pressure. It can be designed as a fabric or braid.

9 shows that pressure chambers 30, which can be designed as pressure hoses 50 and which can be connected to one another or separated from one another, are completely covered by a cover 40 and are therefore arranged in a protected manner. The cover 40 also keeps the pressure chambers 30 at a distance from a user.

10 shows a cover 40 or protector 42 which has recesses 60 which accommodate pressure chambers 30 or pressure hoses 50. The uncovered side of the pressure chambers 30 or pressure hoses 50 points away from the back of a user. The cover 40 is thus arranged between the pressure chambers 30 and the back of a user. The recesses 60 can be undercut so that the pressure chambers 30 are held captively on the protector 42.

In the embodiment of a protector 42 of FIG. 11, the protector 42 has two halves 42.1, 42.2 or half-shells, between which the pressure chambers 30 or pressure hoses 50 are arranged.

The illustrated protectors 42 can be arranged on a backpack or a vest so that they have direct contact with the back of a user or, in the case of a backpack, they can be arranged, for example, in an inner compartment of the backpack. 12a shows a base part 502 of a protection system 500. The base part 502 includes a carrying system 504, which in the exemplary embodiment shown has shoulder straps 506 and hip belts 508. A sensor 510 is arranged on the shoulder strap 506 and is connected via an activation cable 512 to a shut-off device (not shown here). The shut-off device is arranged between a pressure chamber 30 and an airbag 514. The pressure chamber 30 is integrated into a protector 42, which are arranged together on the base part 502. Instead of an activation cable 512 to trigger the airbag 514, an electrical, pyrotechnic or other triggering option can be provided to open the shut-off device. An air-permeable suction area 516 is also provided on the base part 502, through which ambient air can be sucked in when the airbag 514 is inflated with support through a Venturi nozzle.

A luggage part 520, which is shown in FIG. 12b, can be connected to the base part 502. In particular, luggage items 520 of different dimensions can be coupled to the base part 502. To connect the luggage part 520 to the base part 502, connecting means 522, 524 can be provided, which are firmly sewn to the base part 502 or the luggage part 520. The connecting means 522, 524 can be designed as a loop and toggle. In addition, connecting means 526, 528 can be provided, which can be designed, for example, as part of a zipper. Predetermined tear points 530 can be provided on the luggage part 520, through which the airbag 514 can unfold when it is inflated.

Fig. 12c shows the protection system 500 designed as a backpack in the connected state.

In the embodiment of a protection system 600 according to FIGS. 13a to 13c, a base part 602 and a luggage part 620 are again provided. In contrast to the previous exemplary embodiment, the pressure chamber 30, the protector 42 and the airbag 514 are arranged on the luggage part 620. Accordingly, the luggage part 620 has an air-permeable material 516 in the event that the airbag 514 is to be additionally inflated with ambient air. Otherwise, the elements that correspond to those of the protection system 500 are marked with the same reference numbers.

Fig. 14a shows a first connecting means 522, which has a buckle 550, in particular made of metal, preferably made of aluminum or stainless steel. The buckle 550, which can also be viewed as a toggle, is connected to the base part 502 via a webbing 552.

14b shows a second connecting element 524, which is designed as a folded and sewn webbing 554. The webbing 554 is firmly sewn to the luggage part 520, 620.

14c shows connected first and second connecting elements 522, 524.

Fig. 15 shows a protector 700 with a back area 702 and side areas 704, 706. The side areas 704, 706 are intended to be arranged laterally on the torso of a user, i.e. in the rib area. In particular, a user's armpits or arms are free, so that their freedom of movement is not restricted.

The protector 700 has one or more pressure hoses 708 as a pressure chamber. The pressure hoses 708 can be filled with a gas, in particular air, at pressures greater than 200 bar, in particular in the range 250-300 bar. The pressure hoses 708 can be filled once or multiple times. They may have a filling valve. The pressure hoses can be connected to an airbag. The pressure hoses 708 are bendable when filled, so that they can be laid in the protector when filled with gas under pressure (>200 bar). In the protector 700, the pressure hoses 708 have a three-dimensional arrangement/bend. The protector 700 can be designed with two half-shells, so that the pressure hoses can be inserted into and removed from one half-shell and can be covered by the other half-shell. One or the half shells thus represent a cover to protect the pressure hoses 708.

Optionally, the protector 700 can extend into the rump area. Pressure hoses can also be arranged there.

Because the side regions 704, 706 are provided in which the pressure hose(s) 708 can be arranged, a large amount of gas or compressed air can be stored.

The protector 700 can be part of a protective system, for example a vest. It can have a shut-off device or can be coupled to one, the shut-off device interacting with a triggering device.
