An active bolster mounts at an interior trim surface of a passenger compartment in an automotive vehicle. A plastic-molded front wall deploys in a deployment direction toward a passenger in the passenger compartment. A plastic-molded back wall is joined around a substantially sealed perimeter with the front wall to form an inflatable bladder. The back wall includes at least one substantially circumferential pleated baffle and a plurality of attachment towers projecting from a central region disposed within the baffle to join with a reaction surface. An inflator couples an inflation gas into the inflatable bladder in response to a crash event of the vehicle. At least one of the attachment towers includes an elongated notch sunk partially into a surface of the attachment tower to provide a thinned wall section configured to tear open at a predetermined pressure during inflation.
