Technologies used

In this chapter we explain the technologies that the manufacturer uses in this product.

MIPS
The MIPS® safety system is designed to provide additional protection for helmets in a wide range of crashes. In certain impact situations, the MIPS system can reduce dangerous forces that might otherwise be transmitted to the helmet wearer's head.

1. Conventional helmets are designed and tested for a straight impact. However, in most cases the impact occurs at an angle, which can cause rotational movements for the head.

2. These rotational movements can cause brain injuries.

3. The low-friction shell is designed to help reduce the rotational movements acting on the head in certain cases of an oblique impact.

Straight impact – oblique impact

The brain is typically more sensitive to rotational motion than linear motion because it has a shear strength similar to that of water or gel. When rotational motion causes different areas of the brain to move out of alignment with one another, the tissue can become stretched, causing concussions or other brain injuries.

Rotational motion is a common cause of concussions and more severe brain injuries from an angled impact to the head. The MIPS system consists of a low-friction shell that is attached inside the helmet. The low-friction shell is designed to slide slightly inside the helmet during an accident so that forces can be diverted away from the head. This is intended to help reduce the risk of brain injuries.

Most conventional helmets are designed for a straight impact, but the impact occurs at an angle in most cases. The low-friction shell can reduce the rotational forces of an angled impact.

Security system based on the brain

Unlike traditional helmets, which are designed and tested primarily for a straight-line impact, the low-friction shell of the MIPS system mimics the brain's own protection system against rotational motion. Cerebrospinal fluid is our natural protection system that allows the brain to move offset from the skull.
