A laminate article for damping mechanical vibrations. One embodiment of the damping article includes a neoprene layer, a foamed polyurethane middle layer and a nonformed polyurethane layer. The layers are preferably adhered in an overlaying relation. The article reduces at least 40 % of high frequency mechanical vibrations (200 Hz - 1250 Hz) otherwise transmitted to the wearer.

L'invention concerne un article stratifié amortissant les vibrations. Dans un mode de réalisation, cet article comprend une couche de Néoprène, une couche intermédiaire en mousse de polyuréthane et une couche en polyuréthane non-mousse. Ces couches sont assemblées de préférence dans une relation de superposition. L'article de l'invention réduit au moins 40 % des vibrations mécaniques hautes fréquences (200 Hz - 150 Hz), autrement transmises à l'utilisateur.
