4 1. SAFETY RESEARCH Crash and head injury dynamics New materials performance Racing experience 4 PlaquetteAnglaise.indd 4 5/12/06 17:13:52

5 Shark combines the knowledge from these three critical areas to focus on this one leading objective: To minimize the potential injury to the brain, the helmet must absorb the maximum amount of energy in the minimum amount of time during the first impact on one spot. 5 PlaquetteAnglaise.indd 5 5/12/06 17:13:53

6 SHARK has developed better ways to optimize absorption of impact energy 6 PlaquetteAnglaise.indd 6 5/12/06 17:13:53

7 Shark studies motorcycle accident and head injury data to develop an extensive understanding of helmet safety dynamics. Working with CEESAR, a leading European crash and injury analysis center, detailed statistics regarding motorcycle accidents and head impacts are used to understand variances in position and type of impact, ability of various materials to dissipate and manage impacts, and the resulting variance in injury results. Coupled with Shark s extensive racing experience and high-technology laboratory research, Shark is on the leading edge of helmet safety research. 7 PlaquetteAnglaise.indd 7 5/12/06 17:13:53

8 Impact Analysis Impact analysis dictates that the correct balance of managing these three factors will result in optimum safety: A deep penetrating impact on one spot will deliver too many g forces resulting in a head injury. Speed at impact, together with mass, defines total energy Angle of impact defines potential reach of the energy to the head Surfaces giving and receiving impact will modify angle An impact absorbed too slowly will result in brain deceleration duration being too long to protect from head injury. Optimized rapid deceleration and impact absorption manage to minimize potential brain injury. This is Shark s choice. 8 PlaquetteAnglaise.indd 8 5/12/06 17:13:53

9 This notion is given by two datas: The deceleration in «g» (1g=± 9,8 m/s 2 ) The H.I.C. (Head Injury Criteria) integrating deceleration and duration DECELERATION RECEIVED TOO HIGH >275g Deceleration (g) g Limit exceeded time (milliseconds) 275* DURATION OF ABSORBTION TOO LONG H.I.C. exceeded Deceleration (g) time (milliseconds) 275* OPTIMISATION OF DECELERATION AND DURATION OK Deceleration (g) time (milliseconds) 275* 9 PlaquetteAnglaise.indd 9 5/12/06 17:13:54

10 1. SAFETY RESEARCH Racing experience Our commitment toward racing is driven by our commitment to the satisfaction and safety of our customers. Racing is extremely demanding for performance and safety, and thus, is very instructive for our development efforts. Through our racing experience and testing, we are able to reach higher levels of quality and performance in our helmets and face shields. 10 Outstanding safety Excellence in comfort and venting Optimum optical performance across a range of conditions (night, rain, fog, etc.) Best possible weight and balance Aerodynamics and noise reduction These variables are essential criteria for success in racing. We also recognize that these are the same criteria that our customers use to choose a helmet. That is why Shark builds helmets to the highest standards and makes these helmets available to everyone. Our customers deserve the same level of performance safety and quality as any racer. PlaquetteAnglaise.indd 10 5/12/06 17:13:58

12 2. HELMET DEVELOPMENT Shark Helmet Safety Approach 12 PlaquetteAnglaise.indd 12 5/12/06 17:14:19

13 T VERY RIGID OR MORE FLEXIBLE STRUCTURES? Impact management involves dissipation of impact over a larger area coupled with flexible absorption of energy. Recent development in automotive safety incorporate crumple zones to dramatically improve crash management. Rather than a rigid structure, an effective design takes the energy into the structure to reduce the deceleration energy reaching the body. Helmet safety works by following the same principle. 13 PlaquetteAnglaise.indd 13 5/12/06 17:14:20

14 SHARK HELMET CONCEPT tec shell outside + Fin-Shock inside SIMPLE OUTSIDE, COMPLEX INSIDE: 3 TEC-shell Different structure for different areas: Shark is making a balance between outer and inner shell. Where the shape of the shell makes it harder, the inner shock absorber must be softer. Where the shape makes the shell more flexible (i.e visor aperture), the inner shock absorber must be more rigid. Shark uses the right structure & combination to achieve this balance, choosing between glass, carbon, aramid fibers, (Hi-Tec line) and thermoplastic resins (Performance line). Shark develops also new shapes of shock absorber to optimize their efficiency PlaquetteAnglaise.indd 14 5/12/06 17:14:24

15 1 1 Shark fin-shocks, a Shark development As opposed to a solid liner of EPS (Expended poly styrene) foam, or even one with variable densities, Shark s research has led to the development of the Fin-Shock structure EPS liner. These innovative «FIN-SHOCKS» that differ from other helmets, collapse, compress and flex during impact, absorbing more energy with more progressivity, and more precision than a solid piece Multi-piece internal shock absorbing structure Shark choses not to make the foam internal shell in one multi- density piece, but in separate parts of different densities in order to be able to control by weight their «hardness» individually. Each area requires different density parts according to each position. 15 PlaquetteAnglaise.indd 15 5/12/06 17:14:27

16 2. SHARK HELMET DEVELOPMENT USING THE RIGHT MATERIALS IN THE RIGHT WAY 16 PlaquetteAnglaise.indd 16 5/12/06 17:14:27

17 Hi-Tec: composite fibers Performance: injection molding Long & continous multi-axial fibres: Distribution of energy Fibres that hold and distribute impact energy: Varied thickness improve performance: Shark uses a combination of long, short, and multiaxial fibers (for the Shark Hi-Tec range) to optimally spread energy over a larger surface area. Through greater flexibility of the entire shell, energy absorption is improved. As a helmet shell does not react the same in all places (due to shape variation), SHARK uses variable thickness of shell material in different part of the shell. 17 PlaquetteAnglaise.indd 17 5/12/06 17:14:36

18 HARD HELMET Stiff shell + soft foam soft foam (Quick deformation - No progressivity) 18 Stiff shell (No deformation - No absorbtion) A hard helmet although appears to sustain less damage does not allow the energy to be absorbed or distributed away from the head and in fact directs a lot of energy directly to the brain. PlaquetteAnglaise.indd 18 5/12/06 17:14:38

19 tec-shell outside & fin-shocks inside shark tec-shell ((more flexible structure) shark fin-shocks (calculated deformation area for a progressive absorbtion and dissipation of energy) Deformation + absorbtion of the shell comes through partial destruction (remember the car crumple zone concept) The Shark Tec-Shell and Fin-Shocks, working like the crumple zones in automotive construction, absorb and distribute the impact energy through their controlled deformation and thus minimize the amount of impact energy reaching the brain. 19 PlaquetteAnglaise.indd 19 5/12/06 17:14:40

20 3.PRODUCTION quality Through demanding quality control, Shark insures that each helmet delivers the effective safety and comfort desired. A fiber craftsman signs each helmet shell Highly skilled production staff check each step of the process for specification Desired fiber distribution is measured and approved for each shell Hi-tec composite fibers for top performances All production and assembly is done in Shark factories where quality can be controlled 15% of Shark s total staff is dedicated to Quality Control 20 PlaquetteAnglaise.indd 20 5/12/06 17:14:44

21 SIGN,WEIGH,OBSERVE High technology production tools cutting high pressure water jet robots Routine post-production testing is done to monitor final products Technical industrial equipment ensuring precision and quality. More than 5000 helmets tested each year for quality control. 21 PlaquetteAnglaise.indd 21 5/12/06 17:14:47

23 Helmet materials can be severely damaged by chemicals and sunlight, and certainly by any impacts. Never put your helmet in a situation where it can be bumped or dropped. Never use solvents or chemical cleaners, stain removers, or paints on the shell. Never let the shell or liner be exposed to chemical fumes Urban range (including gasoline!). And know that nature s sunlight (UV rays) will deteriorate the materials as well, so use your helmet bag for storage and protection. See the owners manual for further instructions regarding the use of your helmet.
