DEVICE AND METHOD FOR PROVIDING STRUCTURAL REINFORCEMENT AND/OR SOUND AND VIBRATION CONTROL WITHIN THE CAVITIES OF HOLLOW MEMBERS OF A VEHICLE BODY

摘要

An assembly for providing structural reinforcement and/or sound/ vibration damping to a hollow member of a motor vehicle is provided which contains an injection-molded carrier (9) made of a heat resistant thermoplastic composition, at least one of the first side (10) and the second side (15) of the carrier (9) has at least one receptacle (12) adapted to receive and retain an insert (1) comprised of a heat- expandable resin composition. The carrier (9) may have a plurality of openings (11) in at least one of the first side (10) or the second side (15) forming a grid or lattice and the assembly may include a mounting member (20) adapted to fasten the carrier (9) to an interior wall of a hollow member.
