Helmet Philosophy

Fundamental to our helmet philosophy is the fact that the ultimate helmet exists in the combination of world class impact protection, low volume and low weight. 

Our rule is never to shave off weight by compromising the performance. It is achieved by innovation and engineering, brought to life with the best materials and the most advanced manufacturing methods. Our distinctive design and attitude is reflected in the products and is an essential role in each creation and concept.

 

 

All our helmets are constructed with interconnected layers of
protection, enabling us to create helmets with low volume, light weight
and still offering world class impact protection. Our highest
performing helmets consists of four layers illustrated beneath:

 

Sweet Protection helmet construction safest

 


 

01 SHELL

Each shell consists of several areas that has variable elasticity and rigidity. The properties
are tuned to work with the anatomy of the skull, protecting the week spots without
adding unnecessary weight or volume.

 

 

02 LINER
The liner is the main shock absorbing structure. The main liner is made out of relative low density EPS foam which is tuned to match the properties of the shell. The EPS foam has ideal crush characteristics to effectively reduce forces in an impact.
 

 

 

03 IMPACT SHIELDS

Sweet Protection impact shields distributes impacts from the inside over a larger
surface area. Works in areas where the heads' geometry has a sharper radii, such as the forehead or rear occipital lobe.

 

 

04 MIPS
The MIPS brain protection system is a helmet-integrated, low friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head. 

 


 

01 SHELL TECHNOLOGIES

The outer shell is the first layer of protection. We use shells with variable rigidity and elasticity. Optimised to give the ultimate protection with the variable geometry of the head.

CRP SHELL TECHNOLOGY
Carbon Fiber Reinforced Polymer Shell (CRP) provides an incredible strength to weight ratio, rigidity and impact performance. By carefully laminating fibers with different properties and directions, we’re able to create a superlight, optimized helmet shell. An invention from the cold war put to good use. 

 

GRP - GLASSFIBER REINFORCED POLYMER SHELL
Glassfiber Reinforced Polymer shell (GRP) provides a strong and lightweight shell with excellent impact performance. The GRP shells are laid up with several different pre-preg materials and cured with high temperature and pressure to create a high quality shell without weak spots. The rigidity and elasticity varies throughout the shell surface. 

 

TLC - THERMOPLASTIC LAMINATED CARBONFIBER
Combines the elasticity of injection-molded thermoplastic with the rigidity and strength of carbonfiber. It enables us to very effectively tune the shell for different properties in different areas for optimized performance. 

 

ABS - THERMOPLASTIC SHELL - SUPERLIGHT
Our injection molded ABS Thermoplastic Shell – Superlight is very impact resistant through its special rubber toughened construction. The shell is molded with extreme precision to offer the best performance to weight ratio. 

 

CDIP - COMPOSITE DROP IMPACT PROTECTION
An internal composite shell that covers the crown area of the helmet. The purpose of the Composite Drop Impact Protection (CDIP) shell is to disperse impacts from falling objects while allowing us to keep the volume of the helmet down. 

 

IN-MOLD CONSTRUCTION
In-mold construction is a technique that directly fuses the shock absorbing EPS liner with the Polycarbonate shells to create a lightweight and strong structure. 

 

 

02 LINER

The main liner is made out of relative low density EPS foam which is tuned to match the properties of the shell. The EPS foam has ideal crush characteristics to effectively reduce forces in an impact.

Geometry makes a big difference in an impact: The example underneath shows the same cube being dropped from the same height onto a soft foam. in the example to the left the cube is dropped with its flat surface hitting the foam. The impact will be over a large surface area, which means the soft foam will be ideal to absorb the impact. In the example to the right the cube is dropped on its corner. This provides far less surface area, and the cube will travel through the foam without the foam being able to slow it down/absorb the impact.

 

SOFT FOAM (EPS)

 

On soft foam an impact will disrupt the linear forces over a large surface and sink into the foam “slowly”, and slow down the object sufficiently.

An impact in the side on soft foam will cause the object to go straight through, there are not enough mass in the foam to stop the object.​

 

HARD FOAM (EPS)

 

On hard foam the outcome from the same test will give the complete opposite result. When the foam is hard it won’t give in to slow the object down. Resulting in a high g-force.

An impact in the side on hard foam will result in a significant reduction in g-forces. The object has enough strength for it to make the material give in, resulting in a reduction in the g-forces.​

 

This tells us that soft foam is good for flat surfaces, and hard foam is good for corners. Our heads consists of both flat surfaces and sharp corners; which means that the shock absorbing structure should have both hard and soft foam depending on the geometry of the head.

 

 

 

03 IMPACT SHIELDS

The impact shield is additional feature to slow down the forces of an impact. Harmonizing with the EPS liner. Impact shields distributes impacts from the inside over a larger surface area. Works where the head has a sharper geometry.

 

 

 

IMPACT SHIELDS
Helmets with Impact Shields feature a molded shock absorbing EPS liner with Impact Shield inserts that provide unsurpassed performance for shock absorbance. This is our premium impact protection technology. It distributes impact from the inside of the helmet over larger areas in crucial zones where the head has a sharper geometry (front and back).

 

INTEGRATED Impact Shields
This is our impact protection technology integrated in the EPS core of a helmet. Through a strategic placement of volumes and ribs in curved shapes, it creates an optimized impact geometry, distributing the impacts over a larger surface area where the head has a sharper radii (front and back).  

 

04 MIPS

MIPS Sweet Protection Rotational impact

MIPS (Multi-directional Impact Protection System)


A revolutionary technology developed to reduce brain injuries. By allowing the helmet to rotate slightly relative to the head upon impact, the helmet absorbs more of that rotational force, adding better protection than helmets not equipped with MIPS. Conventional helmets are tested by dropping them vertically onto a at surface. MIPS is designed to deal with how most accidents actually occur, with oblique impacts to the head. MIPS sets a new standard in helmet safety. 

 

The MIPS layer rotates relative to the impact force and absorbs more rotational force to the helmet, thus reducing rotational forces on the brain.
