Protective capability of bicycle helmets.
Cycle helmets that meet UK and US standards have been tested. The mechanisms of energy absorption for frontal and side impacts have been analysed. A good helmet should protect the wearer for impacts up to 15 mph into a rigid flat surface.
متن کاملRisk compensation and bicycle helmets.
This study investigated risk compensation by cyclists in response to bicycle helmet wearing by observing changes in cycling behavior, reported experience of risk, and a possible objective measure of experienced risk. The suitability of heart rate variability (HRV) as an objective measure of experienced risk was assessed beforehand by recording HRV measures in nine participants watching a thrill...
متن کاملOblique impact testing of bicycle helmets
The performance of bicycle helmets was investigated in oblique impacts with a simulated road surface. The linear and rotational accelerations of a headform, fitted with a compliant scalp and a wig, were measured. The peak rotational accelerations, the order of 5 krad s when the tangential velocity component was 4 m s, were only slightly greater than in comparable direct impact tests. Oblique im...
متن کاملBicycle helmets--are they up to standard?
On the 3 September, British Columbia's new mandatory bicycle helmet law came into effect. All cyclists on public roads and highways are now required to wear a bicycle helmet that meets one of the following standards CAN/ CSAD1 13.2-M89, Snell B-90, B-90S, B-95 and N-94, ASTM F1447-94, ANSI Z90.4-1984. The implementation of this law largely reflects the unremitting efforts of Glenna Ayerst, Dire...
متن کاملImproving the sun safety of bicycle helmets.
To the Editors: The incidence of sun-induced skin cancer is rising and the eyelid and face are frequent sites of involvement.1,2 Sun exposure can also predispose to pterygium, climatic droplet keratopathy, cataracts, and perhaps macular degeneration. The majority of the skin’s lifetime sun damage occurs during childhood.2 More than 70% of American children ages 5 to 14 years (27.7 million child...
