FIELD: transportation.
SUBSTANCE: group of inventions relates to embodiments of an active bolster for an interior trim surface of an automotive vehicle. Bolster comprises a plastic-moulded outer trim panel having a closed-loop bonding section on an inside surface, a plastic-moulded expandable bladder member having a central attachment section configured to attach to a support structure of the vehicle, a bonding flange along a peripheral edge, and a baffle section between the central attachment section and the bonding flange. Closed-loop bonding section and the bonding flange are configured to define a substantially closed toroidal region therebetween, and an attachment which is injection molded in-situ and fills the toroidal region.
EFFECT: as a result of the in-situ moulding of the attachment in the toroidal region, the trim panel and bladder member become bonded via the attachment resulting in a high bonding strength.
