24、erland, Turkey and the United Kingdom. 1) Under development BS EN 1621-4:2013EN 1621-4:2013 (E) 5 Introduction Motorcyclists inflatable protectors are devices either embedded within or worn on top of other clothing, which aim to reduce the severity of injuries in case of motorcycle accidents. The pr

25、otectors covered by this standard give protection only when inflated. The performance requirements have been selected to provide the best practical compromise between protection, comfort, and ergonomic requirements. Protectors that are too stiff or heavy will not be worn. The test methods are design

26、ed to provide information on protection against mechanical impacts. The force levels in the tests do not relate directly to the forces riders are exposed to in accidents, but experiences have shown that products meeting the requirements of this European Standard may reduce the severity of injuries c

27、aused by impacts. In order to encourage the adoption of certified protection by the highest possible number of users, two performance levels are specified for inflatable protectors. These are level 1 for protectors designed to give protection whilst having low ergonomic penalties associated with its

28、 use and level 2 for protectors providing an increased protection with respect to level 1. There may be, however, weight and restriction penalties associated with level 2 protection. BS EN 1621-4:2013EN 1621-4:2013 (E) 6 1 Scope This European Standard covers requirements and test methods for mechani

29、cally activated inflatable protectors for motorcycle riders (in the following text called protector“). It specifies the minimum level of protection, the minimum intervention time of inflated bag, and the minimum coverage to be provided by motorcyclists protectors worn by riders. The requirements of

30、this standard are applicable to various design of inflatable protectors and refers to all body areas and their combinations which are claimed to be protected. Inflatable protectors covered by this standard may be incorporated in motorcycle garments or equipped with by appropriate restraint systems a

31、nd worn on their own. This European Standard contains the requirements for the performance of the system during an accident and details of the test methods, requirements for sizing, ergonomics, innocuousness, labelling and the provision of information. Inflatable protectors other than mechanically a

32、ctivated are not covered by this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
