COMFORT PADDING
The comfort padding inside a helmet is a crucial component for rider safety and enjoyment. The padding serves multiple purposes - absorbing impact, wicking away moisture, preventing the helmet from rubbing, and ensuring a proper fit.
The padding production starts with cutting foam or fabric materials into the required shapes and sizes. The foam can be open or closed-cell, with open-cell being more breathable and closed-cell providing more support. The fabric is often a technical performance material designed to wick sweat.
Precise die cutting machines are used to cut the padding pieces efficiently and accurately. The pieces are then assembled into pads and inserted into designated areas inside the helmet lining. This is done either by hand or using specialized equipment for large scale production.
VENTILATION AND REAR LIGHT:
Perfect combination of rear taillights and vents for safety and comfort
Proper ventilation is crucial for a safe and comfortable bicycle helmet. Helmet vents allow air to flow through the helmet, cooling the rider's head. The number, size, shape, and placement of vents all factor into a helmet's ventilation system.
Most quality helmets have between 12-25 vents. More vents provide better airflow, but also compromise the helmet's structure. Large front vents pull air into the helmet, while rear vents expel warm air. Top vents assist with updraft. The best helmets find a balance between sufficient ventilation and safety.
Vent design affects airflow too. Vents with smoothed edges and contoured shapes improve airflow. Strategic vent placement draws air over hot spots like the forehead. Channels between vents guide air through the helmet. Some helmets integrate ventilation into the retention system with padded cups that lift the helmet slightly off the head.
Advanced helmets use computational fluid dynamics (CFD) software to optimize vent design. CFD models air movement to pinpoint areas of high heat concentration. Engineers tweak vent shapes and placements to target ventilation to these hot spots. Prototypes are then wind tunnel tested to confirm ventilation efficacy.
