This invention is about a new and improved protective helmet, specifically designed to be more comfortable and safer than existing ones. Imagine a helmet that has two main parts: an inner layer that comfortably fits your head, and a tougher outer layer that sits over it. The clever part is that these two layers aren't directly touching. Instead, there are small ribs in between them, creating a little air gap. This gap acts like an insulator, stopping heat from the sun or hot environments from reaching your head, making the helmet much more comfortable to wear for long periods. Another great feature is that the inner part of the helmet can be removed and replaced. This means you can customize the fit to your head perfectly, or replace just the inner part if it gets damaged, without having to buy a whole new helmet. The outer shell is super strong, made from tough plastics, and even has built-in features like a smooth edge (no need for annoying rubber strips) and integrated spots to attach a visor. Plus, it has special vents that let sound in, so you can hear properly while wearing it. Basically, it's a lighter, stronger, cooler, and more comfortable helmet designed to keep you safe and productive, especially for people like police officers and security personnel.

Existing protective headgears suffer from several critical shortcomings. They are typically one-size-fits-all, leading to discomfort and an improper fit for individual wearers. Furthermore, the use of hard, heavy materials for their shells makes them uncomfortable for prolonged use, often causing neck pain and associated health issues. A significant problem is the direct transmission of heat from the outer shell to the wearer's head, especially in hot environments or during extended exposure to sunlight, leading to further discomfort. Moreover, conventional multi-layered helmet structures have proven inadequate in providing sufficient strength to withstand high impact forces. Finally, current designs often incorporate external components like rubber beading and separate visor mounting mechanisms, which increase manufacturing complexity and can compromise the overall structural integrity and strength of the headgear.
- Dual-Shell Design with a Gap: The headgear features an inner shell and a detachable outer shell. A plurality of ribs are sandwiched between these shells, creating an insulating gap. This gap prevents heat transmission from the outer shell to the inner shell, significantly increasing wearer comfort, especially in hot conditions or prolonged use under sunlight.
- Enhanced Impact Resistance: The combination of the inner shell, outer shell, and the strategically placed ribs forms a composite shell structure that provides superior impact resistance compared to existing designs. The ribs (preferably half-round and perpendicular to the surfaces) contribute to the overall strength.
- Customization Capability: The detachable inner shell allows for easy replacement or customization according to individual wearer requirements, without needing to replace the entire outer shell. This addresses the "one-size-fits-all" problem and allows for better fit and comfort.
- Improved Hearing: The headgear incorporates sound vents on the outer shell, arranged in a specific pattern to allow sufficient sound to pass through, aiding the wearer's hearing.
- Extended Neck Protection: The outer shell extends circumferentially in a downward direction to conform to the shape of the wearer's neck, offering additional protection to the rear portion of the neck.
- Outer Shell Material: ABS-PC
- Rib Thickness: Minimum 3.4 + 0.7mm, Maximum 4.2 + 0.7mm
- Inner Shell Material: Polystyrene
- Density: 30 (kg/m³)
- Sizes: Large (64 cm circumference) and Medium (56 cm circumference)
- Visor Material: Polycarbonate, thickness 2mm, visibility auto 85%, fog-proof, and scratch-proof
The helmet design is finalized, featuring improved ergonomic and structural elements. It is ready for mass production.
