védsisakok

Védsisakok, commonly known as protective helmets, are designed to safeguard the head from injury. They are used in a wide variety of activities where head trauma is a risk, ranging from industrial work and construction to recreational pursuits such as cycling, motorcycling, and contact sports. The primary function of a védsisak is to absorb and dissipate the force of impact, thereby reducing the severity of potential head injuries, including concussions and skull fractures.

The design of a védsisak typically involves a hard outer shell made from materials like polycarbonate, ABS plastic, or fiberglass, which resists penetration and distributes impact forces. Beneath this shell is a shock-absorbing liner, often made of expanded polystyrene (EPS) foam, which compresses upon impact to cushion the blow. Many helmets also feature a retention system, commonly a chin strap, to keep the helmet securely in place during an accident.

Different types of védsisakok are tailored to specific activities. For example, construction helmets are built to protect against falling objects, while cycling helmets prioritize ventilation and aerodynamics along with impact protection. Sports helmets, such as those for American football or hockey, are designed for high-impact collisions and may include face cages or masks. Proper fit and maintenance are crucial for a védsisak to provide optimal protection. Helmets should be replaced after a significant impact, even if no visible damage is apparent, as the internal protective properties may be compromised.
