Protection zones

Motorcycling is one of the most fascinating, albeit not entirely harmless, hobbies. Protective clothing, modern airbag jackets and additional protectors reduce the risk of injury.

The safety awareness of motorcyclists has changed significantly over the past 25 years.

The introduction of mandatory helmets made a decisive contribution to this. But in addition to the mandatory head protection, gloves, sturdy boots and driving suits made of leather or textile have long been part of the basic equipment of most bikers. Technical advances in the development of new, abrasion-resistant textile materials, new processing techniques and the continuous improvement of protective protectors also contribute to reducing serious injuries in accidents.
For over a year now, clothing manufacturers have been trying to further reduce the risk of injury with airbag vests and jackets, the air chambers of which unfold in a flash in the event of an accident and protect the upper body and cervical vertebrae (see MOTORRAD 16/2001). In the meantime, other providers of this technology, which is new in the clothing sector, have been added.
On the following pages, MOTORRAD offers an overview of the current range on the German market. Mugen Denko, the Japanese developer of the technology most frequently used to trigger the airbag with a CO2 cartridge activated by a pull cord, offers four of its own models at prices between 307 and 384 euros. However, these jackets can only be obtained from the Internet (www.hit-air.com), as there are no importers for the European area.
With the exception of Dainese, all airbag jackets and vests work according to the same triggering principle: to activate the airbag, the driver connects the jacket’s ripcord to the motorcycle. If the rider and motorcycle separate in the event of a fall or an accident, the resulting jolt triggers a spring mechanism that punctures the CO2 cartridge, causing the air chambers of the airbag to inflate in a flash.
According to the manufacturer, the time required to fill the chambers is between 0.2 and 0.8 seconds – certainly too long for a head-on collision with another road user. Nevertheless, there are enough accident situations in which the chambers can unfold in time. After a highsider, in which the driver is catapulted from the motorcycle in a high arc, or after a short slide over the asphalt and then crashing into the guardrails, the required deployment time is always sufficient and the airbag can fulfill its protective function.
So far, Dainese is the only manufacturer to use a contactless, electronic trigger mechanism for the D-Air vest, which continuously calculates their relative acceleration via sensors on the jacket and motorcycle and, in the event of an accident, inflates the airbag within just 0.025 to 0.035 seconds. A very decisive time advantage if a collision occurs.
The disadvantage of the vests is that they have to be worn over protective clothing and neither offer protection from the elements nor have protectors. Airbag jackets have an advantage here. They can be used like normal functional jackets because they have protectors as well as wind and waterproof climate membranes. Only in an accident do they show ?? if the technology plays along – your extra skills and additionally protect the driver with cushioning air chambers. The high release force between 15 and 35 kilograms prevents unwanted inflation. However, if you forget to unchain yourself when dismounting, you run the risk of knocking over your motorcycle.
The future will show which protection technologies will prevail on the market and what developments await us. Because so far we are still at the very beginning of a search for more passive safety when riding a motorcycle.

Emergency call

In the event of an accident with consequences, the first thing to do is to remain calm and to limit the report to the emergency services, whether via the emergency call box or the mobile phone, to four important points. Where did it happen? Precise location information shortens unnecessary searching for the ambulance. 2. What happened? Description of the emergency situation so that the control center can initiate the necessary measures. 3. How many injured are there? The information determines the number of rescue personnel and the number of vehicles. What kind of injuries do the victims have? Even non-medical professionals can report on the condition of the injured person. Is he trapped, passed out, is he bleeding profusely? Does he have open fractures or even head injuries? Caution: The reporting person should always wait for questions from the control center and never end the call himself. If the ambulance service has not arrived after 15 to 20 minutes, it doesn’t hurt to call the emergency call center again and ask about it. Mobile phone users have the added advantage worldwide via the speed dial 112, the emergency call center responsible for erreichen.LandRettungPolizeiBelgien100101Bulgarien150160Danemark112112Finnland112112Frankreich1717Griechenland166 / 151100Grobbritannien999 / 112999 / 112Italien118112Jugoslawien9492Kroatien9492Luxemburg112113Mazedonienm9492Niederlande112112Norwegen113112Osterreich144133Polen999997Portugal112112Rumanien061o55Russland0302Schweden112112Schweiz14417 / 117Slowakische Rep.155158Slowenien112113Spanien061112Tschechische Rep.155158Turkei112155Ungarn104107

That certain something

Protectors that can be pulled underneath increase the passive safety of motorcycle clothing in the event of a fall, sometimes considerably.

The protection factor of the driver’s equipment can be increased with relatively simple means. The keyword is additional protectors. What is meant are the protectors that are available in specialist shops and can be worn underneath. The only requirement: sufficient space under clothing. The market offers suitable products for almost every area (sport, touring, enduro, cross). Crossers, for example, swear by stable, well-ventilated breastplates that protect the back, chest, shoulders and upper arms from (St) impacts. While this voluminous “armor” makes little sense for the street, the mostly tight knee and elbow protectors, which are also used in cross and enduro sports, can also be worn under wide-cut driving suits. The same applies to protector shirts à la Dainese safety jacket. Originally developed for enduro riders, more and more bikers are wearing the all-round protection for the upper body under the touring jacket, which is now offered by many manufacturers. The integrated back protector can even be removed from some models and worn separately with the kidney belt. Back protectors are one of the most frequently purchased retrofit protective measures ?? rightly. Because only a small part of the motorcycle clothing on the market has high-quality protectors in this area. The only way to effectively protect yourself from serious vertebral injuries in the event of a fall is to wear models separately under clothing. Depending on how thick the back protection is, it can get pretty tight, especially under tightly cut leather suits. Buyers of a new suit should therefore definitely take the additional protector with them to try on. Another way of spicing up motorcycle clothing that is lagging behind in terms of safety is complete undersuits with protectors like the model from Wintex. The one-piece consists of a thin fabric that has protector pockets in places at risk of falling.
