Samenvatting
The design of M-bag adopts a multi-buffer structure that may decrease gradually the impacting force to human "body" from air bag. There is an inflexion on the impacting acceleration curve of M-bag. Nearby the inflexion, there is a flat buffer area about -15ms and 2-5g. The flat buffer area makes the buffer process of M-bag close to theoretical buffer process. Although M-bag is not full of gas, its maximum g value during the impacting process is less, about 12-20g when the impacting "body" on 36-40kg and velocity 4.85-5.94m/s. M-bag is safe for children, old men and fragile men, and is forceful for protection passengers during the violent impacting process. M-bag is simple in structure.
