DIN EN 13781:2012-04 EN 13781:2012 (E) 5 Introduction The intention of helmets is to reduce the risk of injury to the skull and part of the head surrounded by the helmet. The protection given by a helmet depends on the circumstances of the accident an
26、d wearing a helmet cannot always prevent death or long-term disability. A proportion of the energy of an impact is absorbed by the helmet, thereby reducing the force of the blow sustained by the head. The structure of the helmet may be damaged in absorbing this energy and any helmet that sustains a
27、severe blow should be replaced even if damage is not apparent. To achieve the performance of which it is capable, and to ensure stability on the head, a helmet should be as closely fitting as possible consistent with comfort. In use it is essential that the helmet is securely fastened, with any chin
28、 strap under proper tension at all times. DIN EN 13781:2012-04 EN 13781:2012 (E) 6 1 Scope This European Standard specifies requirements and test methods for protective helmets for drivers and passengers of snowmobiles and bobsleighs.

46、ll be perfectly smooth. Above the reference plane, the shape shall be in the form of a continuous convex curve, except where shaping is provided for functional purposes. Below the reference plane, irregularities in the curve shall be smoothly faired. The shell shall not incorporate an integral peak
