FIELD: transport.SUBSTANCE: invention relates to automotive industry, particularly, to vehicle body upholstery. Proposed modified laminar acoustic structure of vehicle upholstery comprises interconnected bearing and mounting parts with face bearing part being made up of solid layer of acoustic material. It differs from known designs in that it is composed of, at least, a moulded face bearing part separated by dead-end chamber formed by flanging of face bearing part filled with crushed arbitrary-geometrical shape fragments of porous breathable and solid airproof acoustic materials. Said separate crushed fragments of acoustic materials filing said dead-end chamber represent products of secondary recycling. Mounting part of modified laminar acoustic structure of vehicle upholstery in the zone of said dead-end chamber is lined with protective sound-conducting layer of acoustic material.EFFECT: ease of reuse, better acoustical, ecological weight and cost indices.17 cl, 34 dwg |
