PCT No. PCT/EP92/02717 Sec. 371 Date Sep. 6, 1994 Sec. 102(e) Date Sep. 6, 1994 PCT Filed Nov. 25, 1992 PCT Pub. No. WO93/11001 PCT Pub. Date Jun. 10, 1993.The invention relates to a filler body (1) for acoustic and thermal sealing of hollow spaces in vehicle bodywork, constituted as a molded part of resilient, porous material (4) of sufficient restoring resilience, enveloped in foil, which part is subjected to a vacuum prior to introduction into the hollow space (5). The molded part is self-supporting and has, in the direction of introduction, which is perpendicular to the plane of installation, a large bending stiffness by virtue of a flat, thin intermediate layer (3).
