Samenvatting
Eight airbag configurations were tested using a laboratory test procedure developed to predict skin abrasion potential. Abrasion is predicted when airbag fabric impact with a pressure-sensitive film produces pressures exceeding a threshold value. The effects of airbag design parameters on the fabric velocity and abrasion predictions were investigated. For the airbag modules studied, abrasions were predicted when the airbag fabric impact velocity exceeds 50 to 70 m/s, and when the peak inflator tank-test pressure slope exceeded 160 to 180 kPa/10 ms. Differentiation of airbag modules with respect to abrasion likelihood was found to be fairly insensitive to a range of abrasion-prediction threshold values. (A)
