motorcycle helmet energy absorption
In the postwar era, many technological advances were made in the manufacture of motorcycle helmets. Energy-absorbing foams were developed which could absorb and scatter the force of impact and lessen head trauma from crashes. Improvements were made in all four of the basic elements of the motorcycle helmet: The outer shell, interior lining, flexible foam lining and chin strap.The most important of these components as regards safety in a crash is the foam lining inside of the helmet. Polystyrene foam (to be precise, expandable polystyrene foam or EPS) is present in a thick layer in contemporary motorcycle helmets. EPS is lightweight and can withstand compression, making it a perfect material to use for the lining of motorcycle helmets. This lining absorbs and diffuses the energy of an impact, which the skull of the rider would otherwise bear the brunt of. EPS comes in different types and is used in various thicknesses in the manufacture of motorcycle helmets. Basically, the more foam that is used, the more impact resistance the helmet possesses.
These days, the shell is likely to be made of fiberglass or plastic due to cost and weight. However, more high end helmets are made from (equally light, yet far more expensive) materials such as Kevlar and carbon fibers.

heated motorcycle jackets gerbingsThe manufacturing process of motorcycle helmets is undergoing continual improvement by the companies engaged in making them. Lighter materials and better construction mean constant improvement in motorcycle helmets. There are heavier materials out there for helmets;
While offering good protection, they can crack if dropped, ruining their utility as protective gear. Injection molded plastic is another common material. However, this is not as long lasting as fiberglass and can be broken down by paint and decals. Great care must be taken with what goes onto a plastic helmet.Keep in mind what sort of bike you intend to ride while wearing any helmet you are considering purchasing. Discuss it with the staff at your local shop; the type of helmet that can best protect you in a crash can depend to some extent on what model and make you ride.The Dainese Group Presents the New Generation of Head-to-Toe Protection Systems for Road UseMILAN, Italy (Nov. 8, 2016) – Following the recent introduction of head-to-toe protection systems for motorcycle racing, such as the AGV Pista GP R helmet and the Dainese Mugello R D-air® racing suit, the Dainese Group is proud present the new generation of protection for road use, at years, Dainese returns to EICMA with important news in the world of
protection and presents the new collection of D-air jackets for road use and the new family of certified Pro-Armor protectors. new Misano D-air, Cyclone D-air and Continental D-air jackets, dedicated respectively to sport, sport-touring and urban segments, integrate the brand-new D-air airbag system in its stand-alone version, which means no sensor kits need to be fitted to the motorcycle. the ultimate level of protection is available for all types of road 3D Dainese airbag is the heart of the system. Thanks to an internal structure made of micro-filaments, the airbag deploys in a controlled thickness over its full length and wraps around the rider’s body, providing at the same time maximum protection and comfort. airbag is unique and differs from all other airbags used in theThe pioneering Dainese airbag system has been further improved and now covers neck, collarbones, shoulders, chest and platform and the algorithm—the brain and true intelligence of the
system—have been further improved. Thanks to data acquired from six sensors (accelerometers and gyroscopes) and from the GPS housed in the back protector, the system monitors a rider’s dynamics 1000 times per second and deploys the system in the event of impact, high-side, and low-side with or without tumbling. system equips a new LED interface positioned on the forearm that keeps the rider informed about the system’s operating status. provides power for over 24 hours of continuous use (three times more than the previous battery), and the time needed for a full recharge is down to four hours. future of protection is in the air, and the data gathered by DaineseOver 1,200 deployments documented by the team at the Dainese Science and Research Center over 600,000 miles from tracks and roads all over the world confirm both the efficiency and reliabilityThe analysis carried out on the massive amount of data acquired contributes to further refining the triggering algorithms of
Sixteen years of constant research have led to 35 patents relating to the manufacture of airbags, triggering algorithms, the architecture of the electronic platform and the integration of airbags and protective clothing. new jackets use the latest-generation Pro-Armor back protector to house the electronic platform (sensors, GPS and battery) for the D-air airbag system, achieving unparalleled standards of comfort. new Pro-Armor family of protectors, composed of protectors for shoulders, elbows, back, chest, lumbar region, side and knees, follow an innovative design inspired by fractals, which nature uses to createThe fractal structure emphasizes the characteristics of the carbon-based elastomer that forms the protective component ofThe carbon elastomer absorbs up to 83% of the force that strikes the safety device. The fractal-inspired design provides an extended perforated surface (43% in the case of the back protector) that works in perfect harmony with the variable depth of the protector to
