An airbag which inflates itself in an uncontrolled fashion after a traffic accident can inflict severe injuries to accident victims or to the police, who are frequently the first ones to arrive at the scene of an accident. In a workshop setting, this can cause serious injuries when working near the airbag because the airbag can suddenly shoot out with all of its force. The OCTOPUS® airbag retainer system protects against uncontrolled inflating of the airbag.
|
| The application is conceivably simple: |
|
| The belt plate with the eight belts is placed over the steering wheel and is tightened. The rectangular enamelled tarp is centered and tensioned on the passenger side at the height of glove compartment. |

| History |
| Airbags moved into passenger vehicles in the eighties. It would be unconceivable today to imagine life without airbags. Statistics reflect this as a result of fewer deaths as a result of accidents and less serious head injuries on persons involved in accidents. In the past, various accidents showed that this technology was not always 100% reliable. |
| In various accidents, situations arose for the rescue personnel, which definitely turned out to be dangerous. An airbag that did not inflate properly after an accident can inflate after a delay as a result of cutting work, a spark or some other external influence. Pictures from the USA attest to this problem. |
|

| Danger of Explosions |
The tripping of a driver's airbag, which can develop a speed of up to 350 km/h during unfolding and an axial force of 1,000 kg, the rescue personnel and the accident victim are exposed to a danger that should not be underestimated.
This basic weakness was the reason for the development of OCTOPUS, a mechanical retainer for airbags, which is fitted onto the steering wheel after an accident by the rescuers to protect the rescuers and the accident victim(s).
|
|
To compare this to other products: Safety first. During the development, being sure that no dangers emanated from the actual system itself was of the utmost importance. The first metal prototypes were abandoned and the decision was taken to use a material from which no dangers would emanate.

Metal systems prohibited in the USA
With other mechanical retainers, most of the energy that is released when airbags inflate is absorbed by the steering wheel. The OCTOPUS was designed in such a way that the airbag can unfold as required between the tape lagging and the energy of the exploding airbag must only be partly absorbed by the steering wheel.
Here, one must bear in mind that a damaged steering wheel over which the system is mounted can also turn into a hurling object within the passenger area of the vehicle.
When an airbag unfolds into the OCTOPUS system, the released energy requires a depth of approximately 12 cm. This means that about 70% of the effective area can be kept clear during rescue efforts or other work in the vicinity of the airbag.

| Packaging units and special sizes |
| |
In systems used on the driver's side, we use 39 cm for passenger vehicles, 40 - 45 cm for delivery trucks and limousines.
|
|

As a result of requests from MAN and Mercedes, manufacturers of heavy goods vehicles, the 43 - 50 cm size was developed after the other two sizes. MAN has equipped all the workshops and production areas with such systems as a preventative measure to avoid accidents, as airbags are being installed today at the customer's request.
The system is placed over the steering wheel crown from the left side while the user is standing. You hold onto the fastened belt firmly and pull on the loop on the other end. The unit's impact plate positions itself centrally over the steering wheel. Fitting the unit takes 5 seconds. The TüV Rhineland certified results of 3.3 to 4.3 tons with a permanent load during the product tests. Since the introduction of the system in 1995, 10,000 fire departments, rescue services, police departments and vehicle manufacturers trust this system worldwide. |

| PASSENGER AIRBAG Background Knowledge |
| |
| Passenger airbags are the largest in the vehicle, as they can have a volume of up to 165 litres. This also requires a higher dose of explosive power in order to maintain the time between inflation and when it falls together. |
|
| We think of this in terms of about 47 ms. By comparison: the bat of an eyelid requires 100 ms. The speed that is achieved can be up to 350 km/h and have an axial force of up to 1.2 tons. As result, this airbag is the most aggressive "airbag" in the automobile. The case from the USA documented by pictures shows the delayed firing of a passenger airbag and the remaining slight chance of such dangers to rescuers and victims. |
| |
| Defusing the most aggressive "airbag" |
| |
| To defuse this danger, ELN developed a mechanical airbag retainer system for the driver's side and introduced it on the market in 1995. |
|
The airbag retainer system for the passenger side followed the driver airbag retainer in 1999 after many requests from fire departments. During the development, it was important to be able to adapt the system to various accident situations.
During the installation of the system, we distinguish between two possible applications.
- First, the system is fitted if the roof and the A pillar on the accident vehicle still exists
- Second, the retainer is used to protect against delayed firing, if the roof has been severed from the vehicle. It is also used with convertibles.
Furthermore, it was important during the development that the same materials were selected as those that were used for the driver airbag retainer system to avoid producing any further dangers.

Metal Systems Prohibited in the USA
|
Systems made of metal have been prohibited in the meantime in the USA as these can developed into a weapon in extreme situations.
|
|
With trained staff, the installation time is between 45 and 60 seconds. If we start with the manufacturer's data and use a period of up to 30 minutes as a basis, because the airbagtronics still conduct voltage from the vehicle battery, then a little longer installation time for the passenger airbag retainer in comparison with the system on the driver's side is absolutely justified.
During testing in the development phase, they discovered that about 80% of the effective space is kept free, which in turn facilitates safe working. No one should underestimate the forces that are released, they should always be on their toes. |

| Protective Cover Set |
|
|
Areas of use:
- The large blanket is used, e.g. if the roof of a vehicle is cut off to cover the long cutting edges.
- The smaller blanket is used in the door region to cover any cutting edges when the doors are being removed.
- The protective blankets adhere independently to the vehicle because of the magnets that been sewn into them.
- The protective pockets are positioned over the pillars once the roof has been cut off.
The protective blanket set consists of a protective blanket sized 165 x 65 cm, a protective blanket sized 65 x 65 cm and two protective pockets. All these components are packed in a transit bag.

| A mix of material that withstands everything |
| For these units, we used CORDURA® materials, the most durable nylon by DuPont. The outer skin is made of TREVIRA®, a specially coated tarpaulin, which can be cleaned using normal disinfectants, whenever blood or oil are involved. |
|
Four layers of fleece are sewn in between these two materials. These layers have the characteristic of contracting if they are being penetrated by something pointed or sharp.
While using these systems, an additional air cushion builds up between the individual materials, which offer an additional safety factor. |

| Operation Tents SECTATOR® quick inserts (SEZ Schnelleinsätze), ingeniously convincing technology |
Special The tent frame and the tent roof are all made of one piece. The tent can be set up by two people within 60 seconds. The tent walls are attached with Velcro; the tent legs are inserted into the base plate if the underground is really firm, or if necessary. The tent can be wired to the base plate in parallel to prevent susceptibility to the wind.
|
|
| The tents can be washed at 30°C if the sidewalls or the tent roof becomes dirty. Another highlight is the fact that every tent component can be replaced if it is damaged. Dismantling the SEZ requires very few steps. |
| One further advantage of this technology is that if the tents are used as supply tents in the event of a major incident and a larger area is used for medium injured persons, then another tent can be setup beside it using a connector set. |
|
| |
| The isolating control system
The collapsible signals from the isolating and control technology product series distinguish themselves through their flexibility when in use.
Velcro information signs can be mounted for various operational requirements. This saves purchasing costs since fewer signals have to be bought, but this depends on the various annotations.
Retro-reflective, Euro colours
|
|
The signal triangles are galvanized. The fabric skin is manufactured in the EURO colours and is retro-reflective; therefore signs can be easily recognized from a safe distance, during daylight hours and above all at night.
|
|
| In the event of major situations, interchangeable frames can be used with insertable signs on the trihedron while a warning light can be mounted directly on the collapsible signal or on the actual frame. |
| |
| Flexible right to the final detail |
| |
| The annotations must remain flexible here as well; this is used during operations to orient follow-up auxiliary staff or as a sign post for unauthorized persons. The transit bag holds the collapsible signal and makes it possible to attach up to ten differently worded information signs |
