Let’s get started!
Different Types of Helmet Fastening Systems
The different types of helmet fastening systems are as follows:
1. Double D-ring Fasteners
Double D-ring fasteners are a common type of helmet fastening system. They consist of two metal D-shaped rings, usually made of stainless steel, that are attached to the chin strap of the helmet. To fasten the helmet, the strap is threaded through one D-ring, then looped back and threaded through the second D-ring.
The excess strap is typically tucked away or secured with a snap button. To release the helmet, the strap needs to be pulled out from the second D-ring. Double D-ring fasteners are known for their reliability and strength, as they provide a secure and adjustable fit. However, they may require more time and effort to fasten and release compared to other systems.
How to Fasten a Double D-ring Helmet: Step-by-step Guide
Here are the steps to correctly fasten a double D-ring helmet:
- Start by holding the helmet with both hands, ensuring the straps are untangled and ready to be fastened.
- Place the helmet on your head and position it correctly, ensuring it sits level and snugly on your head.
- Locate the two metal rings on either side of the helmet’s straps. These rings are typically located near the base of the helmet.
- Take the strap with the metal D-rings and insert it from underneath your chin, bringing it up and over the top of your head.
- Pass the strap through both metal rings, ensuring that the strap is not twisted.
- Pull the strap gently to tighten it, making sure it is snug but not overly tight. The helmet should feel secure on your head.
- Use the red strip (maybe a different colored strip in your case) or any additional adjustment mechanisms provided to further tighten the strap, if necessary. Follow the company’s instructions for using these additional features.
- Once you have achieved a comfortable and secure fit, take the loose end of the strap and pass it through one of the metal rings again.
- Push the loose end of the strap through the metal ring until it is securely held in place. Some helmets may have a snap button or magnetic closure to secure the loose end of the strap.
- Double-check that the strap is securely fastened and that there are no twists or tangles in the strap.
- Adjust the position of the helmet on your head if needed, ensuring it covers your forehead and the back of your head properly.
- Lastly, make sure there is proper space between the helmet’s strap and your neck. This space should allow approximately two fingers to pass through comfortably. Adjust the strap tension if needed to achieve the correct fit.
2. Quick Release Buckles
Quick-release buckles offer a convenient and efficient way to secure a helmet. This type of fastening system typically consists of a buckle with a release button or lever mechanism. To fasten the helmet, you insert one end of the strap into the buckle, ensuring it clicks into place.
Then, you press the release button or lift the lever to unfasten the buckle and remove the helmet. Quick-release buckles are designed for easy and quick operation, making them suitable for riders who frequently put on and take off their helmets. They are often used in helmets designed for recreational activities and urban commuting.
How to Secure a Quick-Release Buckle Helmet
Securing a quick-release buckle helmet is a simple process that can be done in a few easy steps. Here is a detailed guide on how to secure a quick-release buckle helmet:
- Position the Helmet: Place the helmet on your head with the front facing forward. Adjust the helmet so that it sits level on your head, covering the top of your forehead without obstructing your vision.
- Adjust the Straps: Locate the straps attached to the helmet. There are usually two or three straps: one that goes around the chin and one or two that goes around the back of the head.
- Chin Strap: Start by adjusting the chin strap. Pull the straps to tighten them around your chin, ensuring a snug fit. You should be able to fit only a finger or two between the strap and your chin.
- Back Straps: Next, adjust the straps at the back of the head. These straps help to secure the helmet in place. Hold the sliders on the straps and tighten them until the helmet feels secure. Again, you should be able to fit one or two fingers between the strap and your head.
- Fasten the Buckle: Once the straps are adjusted, locate the quick-release buckle. It is typically located under the chin, at the junction of the chin strap. Insert one end of the buckle into the other, ensuring that it clicks into place securely. Give it a gentle tug to confirm that it is properly fastened.
- Double-Check the Fit: After fastening the buckle, give the helmet a gentle shake and tilt your head side to side to ensure it doesn’t wobble or shift. If the helmet moves excessively, readjust the straps until it feels snug and stable.
- Perform a Final Check: Finally, perform a visual and physical check of the helmet. Make sure the helmet is level, covering the top of your forehead, and not tilted too far back or forward. Ensure the chin strap is securely fastened and the back straps are properly tightened.
3. Micrometric Buckles
Micrometric buckles, also known as ratchet buckles or quick-adjust buckles, are designed to provide a precise and adjustable fit. They typically consist of a strap with evenly spaced teeth and a ratcheting mechanism. To tighten the helmet, the strap is threaded through the buckle, and the wearer can tighten it by pulling the strap until the desired tightness is achieved. The ratchet mechanism locks the strap in place, preventing it from loosening during use.
For releasing the helmet, a release lever or button is pressed, allowing the strap to be easily loosened and removed. Micrometric buckles are popular for their ease of use, as they offer quick and precise adjustments without the need for rethreading the strap. They are commonly found in motorcycle helmets and other sports helmets.
Strapping a Micrometric Buckle Helmet: Detailed Instructions
Strapping a micrometric buckle helmet is a relatively simple process. The following steps will guide you through the process:
Step 1: Start by adjusting the helmet’s fit
Before strapping the helmet, ensure it is properly sized to your head. Most helmets have an adjustable headband or dial at the back that allows you to tighten or loosen the fit. Adjust it so that the helmet sits securely on your head without being too tight or too loose.
Step 2: Position the chin straps
Locate the chin straps on the helmet. They are usually attached to the sides near the ear area. Hold the helmet by the chin straps, positioning it on your head with the front edge positioned slightly above your eyebrows.
Step 3: Fasten the buckle
Take both chin straps and bring them together under your chin. You’ll notice a micrometric buckle on one of the straps. This type of buckle usually consists of a metal or plastic piece with teeth and a small lever or button for release.
Insert the strap into the buckle: Insert the strap with the loose end into the buckle. Ensure that the strap is not twisted and that it lies flat against your chin.
Step 4: Adjust the strap length
While holding the loose end of the strap, pull it gently until the chin straps are snugly secured under your chin. Make sure the helmet feels comfortable but not too tight.
Step 5: Lock the buckle
Once you’ve achieved the desired fit, lock the micrometric buckle by pushing the lever or button into place. You should hear a clicking sound or feel the buckle engage, indicating that it is securely locked.
Step 6: Check the fit
With the buckle locked, move your head from side to side and up and down to ensure the helmet doesn’t shift or wobble excessively. If it does, you may need to readjust the chin straps or the helmet’s fit using the adjustable headband or dial.
Step 7: Test the stability
Place your hands on the helmet and try to shift it forward or backward. If it moves significantly, the straps may be too loose, and you should tighten them further.
Common Mistakes When Fastening a Motorcycle Helmet
When fastening a motorcycle helmet, it’s crucial to ensure a secure and proper fit for your safety. Here are some common mistakes to avoid when fastening a motorcycle helmet:
Incorrect Strap Placement: One of the most common mistakes is improperly placing the helmet straps. The chin strap should be positioned under your chin and fastened snugly. Avoid placing the strap too far forward or back on your jawline, as it can compromise the helmet’s stability.
Loose Chin Strap: Failing to tighten the chin strap adequately is another mistake. The strap should be snug enough to prevent the helmet from moving or rotating on your head. If it’s too loose, the helmet might come off during an accident or provide insufficient protection in case of an impact.
Unbuckled Strap: Forgetting to buckle the chin strap is a potentially dangerous mistake. Always ensure that the strap is securely fastened before riding. Double-check it by pulling the strap to confirm it’s properly engaged.
Incorrect Strap Length: Adjusting the strap length incorrectly can lead to an ill-fitting helmet. The strap should be adjusted so that it fits comfortably and snugly under your chin. It should neither be too tight to cause discomfort nor too loose to compromise security.
Helmet Positioning: Placing the helmet incorrectly on your head is another mistake. It should sit level on your head, with the front edge sitting just above your eyebrows. Avoid tilting the helmet backward, as it can expose your forehead and compromise the helmet’s effectiveness.
Neglecting Proper Buckle Alignment: The helmet buckle should be aligned correctly and securely fastened. Ensure that both ends of the buckle clip together smoothly and are securely latched. Improper alignment can weaken the buckle’s strength and increase the risk of it coming undone during an accident.
Using a Damaged Fastening System: Regularly inspect your helmet’s fastening system for any signs of damage. This includes checking the chin strap, buckle, and retention system. If any part is worn, frayed, or damaged, it may not provide the necessary protection. Replace any damaged components or, if needed, replace the entire helmet.
