<p>A temper-resistant cover (12) for an airbag (16) includes one or more regions (8) in a surface of the tamper-resistant cover that is/are less tear-resistant than the material which is used throughout the remaining portions of the cover. This tearable portion (8) or portions readily rips upon deployment of the airbag when pressurized gas rapidly fills the underlying airbag thereby allowing rapid deployment of the airbag as desired. Selective locations for the tearable region or regions on the cover desirably may be used to assist in altering the way in which the airbag deploys during a crash or other impact. The tearable regions on the bag cover may be formed by providing mechanical wear to the desired region on the cover. Alternatively, the tearable region or regions may be formed by creating an ultra-sonic tear seam or through the use of a tear tab (33) or tear strip (25) into the cover.</p> |
