FIELD: transportation.
SUBSTANCE: disclosed is an active bolster for an interior trim surface of a vehicle, having a plastic-moulded outer trim panel with a closed-loop bonding section on the inside surface. Plastic-moulded expandable bladder member has 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. Attachment body is moulded in-situ to fill the toroidal region.
EFFECT: as a result of the in-situ moulding of the attachment body in the toroidal region, the trim panel and bladder member become bonded via the attachment body resulting in a high bonding strength.
