The method involves selecting a level of each control factor based on the measured minimum impulse and the measured maximum impulse. The minimum impulse and maximum impulse are measured after inputting each noise factor to each arranged combination comprising of levels of control factors according to an experimental design. The minimum impulse is able to tear a tearseam (21) of the PAB door for operation of the passenger-side airbag (4). The maximum impulse is unable to tear the tearseam of the PAB door in case of a head or body impact. The levels of a noise factor is defined depending on a process condition of laser scoring forming the tearseam on the inner surface of an instrument panel. The control factors and levels of each control factor, that affect a stress distribution and deformation rate of the tearseam, are also defined. |
