Method for improving occupant protection in motor car during front crash, involves lowering force level of beam portion such that vehicle is delayed in lower range, so that occupants are coupled at restraint system

摘要

The method involves delaying a vehicle i.e. motor car, by longitudinal beam structure portions (1a, 1b) of different deformation resistances during front crash and during laying of response time of a vehicle occupants restraint system. A force level of one of the longitudinal beam structure portions is lowered to a determined low value such that the vehicle is delayed in a lower range till reaching forward displacement of vehicle occupants, so that the occupants are coupled at the restraint system over a longer period of time during reduced loading of thorax of the occupants. An independent claim is also included for a device for improving occupant protection in a vehicle during front crash at point of time.
