26、edded within or worn on top of other clothing, which aim to reduce the severity of injuries in case of motorcycle accidents. The protectors covered by this standard give protection only when inflated. The performance requirements have been selected to provide the best practical compromise between pr

27、otection, comfort, and ergonomic requirements. Protectors that are too stiff or heavy will not be worn. The test methods are designed 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

28、, but experiences have shown that products meeting the requirements of this European Standard may reduce the severity of injuries caused 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

29、 protectors. These are level 1 for protectors designed to give protection whilst having low ergonomic penalties associated with its 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

30、2 protection. DIN EN 1621-4:2013-04 EN 1621-4:2013 (E) 6 1 Scope This European Standard covers requirements and test methods for mechanically activated inflatable protectors for motorcycle riders (in the following text called protector“). It specifies the minimum level of protection, the minimum int

31、ervention time of inflated bag, and the minimum coverage to be provided by motorcyclists protectors worn by riders. The requirements of 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. Infla

32、table protectors covered by this standard may be incorporated in motorcycle garments or equipped with by appropriate restraint systems and 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, require

33、ments for sizing, ergonomics, innocuousness, labelling and the provision of information. Inflatable protectors other than mechanically activated 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
