Bell Sidetrack II Child MIPS 头盔 儿童

These kids today… They bike enthusiastically, are often willing to take risks and are finding out more and more trails, bike parks and cool locations. The Sidetrack II remains at eye level: It has an all-mountain design with deep rear head protection. The action-packed styling, complete with a cool visor, further motivates young riders to get on the bike. With Ergo Fit System and No-Twist Tri-Glides they are ready to go in no time. The Sidetrack II is the all-round companion for little heroes.

• No-Twist Tri-Glides™ harness guide
• Sweat Guide™ padding
• Soft brim visor
• ratchet closure
• fly net
• Weight: about 260g

In-mold construction
With the in-mold construction, the robust polycarbonate outer shell is bonded to the impact-absorbing EPS inner shell in one operation while foaming. The helmet becomes tougher without any additional weight. This production process also makes it possible to form significantly better ventilation systems and vents. Compared to traditional helmets, in-mold helmets are lighter and have significantly better ventilation systems.

Ergo-Fit adjustment system
After a thorough revision, the ErgoDial is now called the Ergo Fit™. In addition to a significantly improved adjustment mechanism (no more pressing and turning), it is now also significantly slimmer and less conspicuous.

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 motion than linear motion 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.
