Cold knowledge, why the top motorcycle leather jackets use metal and rubber protective blocks

recently discovered that Dainese, a well-known parts manufacturer, has a series of knowledge columns about personal parts on the Internet. One of the topics discusses the evolution of motorcycle leather clothing and the current top leather clothing design. It also explains why the top racers, or Dainese The top-level one-piece leather product, you can see the reason for the metal protection block. After years of evolution,

racing leather jackets have evolved from simple leather with thickened soft protective blocks in the early days. In recent years, a large number of materials such as carbon fiber and metal have been introduced. In addition, the airbag function protects the rider from instant shocks. We can find that some commercially available leather jackets will have a small amount of metal protective block added to the outer layer. This is also for safety reasons.

First of all, when a rider crashes, generally speaking, we want them to "slide out" instead of "get out". In principle, sliding is a gentle behavior that can gradually weaken the impact after a turn; the bounce generated by rolling , Flip may cause more serious damage to the body and limbs. But usually in these situations, you will slide all the way from the asphalt of the track to the buffer zone. If you are lucky, pat the sand on your body and return to the PIT area to rest.

According to Dainese, although the plastic protective block is made of multiple layers of foamed plastic, it can effectively absorb the impact. At the same time, Dainese still has a certain percentage of plastic protective parts in the leather jacket, but it is definitely not the outer layer. The best protection material. Because of the high friction of the plastic on the asphalt and the heat generated by the friction, the plastic will instantly deteriorate or accelerate wear. Even when it is turned over, the wrongly designed plastic protection block may cause the rider to roll over and cause further injury.

Dainese allows metal to exhibit wear resistance and high heat resistance through metal blocks installed in specific positions. Usually, in Dainese leather clothing, you can find traces of metal protective blocks on the shoulders, elbows, and knees. These parts are usually made of aluminum or Titanium metal is the basic requirement to ensure the flexibility of the rider's activities and not add too much weight. Although the use of metal blocks only accounts for a small part of the one-piece leather jacket, it still has its reasons and effects.
