Fathers, mothers and children ye ride by bike: as you know, those under 16 are required to wear helmets on all roads. Many’re abiding by the law and by putting the helmet to your children, but do you what you are adjusting well?
A bike helmet. NHTSA image.
For a helmet can serve in case of accident, it is essential that it is the right size and is well placed and adjusted.
A maladjusted or too large hull is practically useless.In general, a helmet that does not fit doubles the risk of head injury in an accident, and take loose thetripling compared to a helmet correctly (reference: A systematic review of bicycle helmet use correct ). And according to US studies, children wear the helmet misfitted between 46% and 100% of the time. Yes: in a couple of studies, ALL bad boys wore the helmet.
I do not seem necessary that the helmet is compulsory for children, but I think it makes sense that if you wear it , you should do well. In my city I’m tired of seeing children unbuckled helmet or misplaced. Nor would morethan DGT give parents guidelines to avoid misuse. The helmet should fit tight to be effective.
The US NHTSA has a guide in Castilian to choose and wear a bike helmet. The reproduced here with some minor change. (*)
Anyway, in a specialty store you can ask for help to choose the size and make the first adjustment. It’s a good option. In Mammoth.es, for example, they have bothered to record a video explaining the whole process of adjustment.
Step 1: size
Helmets come in various sizes vary by manufacturer. Measure the circumference of your head to get an approximate size. Try on the helmet to make sure you is properly adjusted (ie, the hull will not slide from side to side). Choose the size you need today: do not buy too large, or not do.
Some helmets bring some extra pillows to adjust the size of the hull.Combines the pads to make is comfortable, but snug.
If the user has grown, remove the pads. If the helmet has a universal ring type setting instead of pads, adjust the ring to make it comfortable, but properly adjusted.
Decathlon also has a short video that explains how to measure head and adjust one of their helmets.
Step 2: the correct position
The helmet should go flat on the head and cover part of the forehead. To test if you have the helmet correctly, place one or two fingers above your eyebrows. To be properly protected, the helmet should touch your fingers.
Step 3: Adjust the chin (chin strap)
Centra left buckle clasp to make it under the chin.You can adjust the straps from the back of the helmet so that the chin strap is longer or shorter. It is easier to adjust the straps if you’re not wearing a helmet.
Step 4: Adjusting the side straps
Adjust the slider on both side straps to form a “V” (below and in front of each ear).
If possible, set the slider to locks into position.
Step 5: Adjusting the chin strap
Fastens the chin strap.
Adjust the strap until the helmet is properly adjusted you, so you can not place more than one or two fingers between the strap and the chin.
Step 6: checking
- Is snug helmet?Open your mouth all you can, likegiving a big yawn. You ‘ll have to feel that the helmet you squeeze head slightly. If not, go back to step 5 and tightens the chin strap.
- Can you move the helmet back?Is it movesmore than two fingers above the eyebrows? If so, it is too loose. Desabróchatelo, and shorten the front strap. Refits the chinstrap and try it again.
- Can you move the helmet forward? Coming to cover your eyes?Then you have to shorten the belt back, re-adjust the chin and repeat the test.
The helmet should be certified and comply with regulations EN 1078 (in Europe).
If you had a stroke, or if the user has grown and no longer fit you, . Must change helmet The manufacturer may suggest you change it after a period of time: Read the instructions.
In general, the hulls are sensitive to extreme heat: do not let the sun in the car or near a heat source summer (heating, dishwasher …) because they can deteriorate.
