Giro Bexley MIPS City Helmet
The Bexley MIPS® is Giro's top-of-the-line helmet for the city, packed with all the features you'd expect from a premium helmet - plus a few more. The compact form of the Bexley MIPS creates an attractive look, but still offers advanced protection and the soft, antibacterial padding ensures comfort. A foldable and replaceable visor protects your eyes from wind and glare, especially when you're going a little faster on an e-bike. The integrated taillight is designed so you don't even know it's there when you're not using it -- but the entire back of the helmet flashes brightly when you turn it on, so you're better seen on the road. Roc Loc® Air ensures an excellent fit and excellent ventilation, the four large ventilation openings can also be easily adjusted while driving. Also thanks to the comfortable ear pads, the Bexley MIPS is extremely comfortable, even in bad weather. The Bexley MIPS is equipped with the Multi-Directional Impact Protection System (MIPS).
Technologies used
In this chapter we explain the technologies that the manufacturer uses in this product.
MIPS
The MIPS® safety system was developed to provide additional protection for helmets in numerous accidents. 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. In most cases, however, the impact is at an angle, which can cause rotational movements for the head.
2. This rotational movement can cause brain injury.
3. The low-friction shell is designed to help reduce rotational movement of the head in certain cases of angled impact.
Straight impact - oblique impact
The brain is typically more sensitive to rotational movement than linear movement because it has a shear strength similar to that of water or gel. When rotational movement causes different parts of the brain to move at different times, the tissues can be stretched, causing concussions or other brain injuries.
Rotational motion is a common cause of concussion and more serious brain injury from an oblique impact to the head. The MIPS system consists of a low-friction shell that is fixed inside the helmet. The low-friction shell is designed to slide slightly inside the helmet in the event of an accident, allowing forces to be directed away from the head. It is said to help reduce the risk of brain injuries.
Most conventional helmets are designed for a straight impact, but in most cases the impact is at an angle. The low-friction shell can reduce the rotational forces of an oblique impact.
Security system with the brain as a model
Unlike conventional helmets, which are primarily designed and tested for a straight impact, the low-friction shell of the MIPS system mimics the brain's own protection system against rotational movement. The cerebrospinal fluid is our natural defense system that allows the brain to move offset to the skull.
