VIBRATION-AND-NOISE ISOLATING COATING Russian patent published in 1997 - IPC

FIELD: transport engineering; protection of vehicle drivers from noise, vibration and other discomfort conditions in winter. SUBSTANCE: coating has outer layer made of elastomer material and support part arranged under elastomer material layer and made in form of grid with hollow cells of square shape. Layer of elastomer material connected to grid forms shock absorbing diaphragms over cells. Diaphragms have at least one projection on outer side. Projection contours are located inside diaphragm contour. Diaphragms provide low frequency vibration isolation. EFFECT: improved quality of vibration-and-noise isolation. 3 cl, 10 dwg
