ABSTRACT:
Flexible vibration damping units, and vibratile products including flexible vibration damping units as components thereof, are provided wherein, in the vibration damping unit, at least one laminar group of flexible strip portions of a flexible framework is included having flexible longitudinally free-ended strip portions in the group firmly secured in the framework to one of the flexible strip portions in the group so as to have the strip portions in the group flex, and relatively move longitudinally with reference to one another, when the framework is flexed, this with the vibration damping unit further being characterized by including visco-elastic means, preferably of a visco-elastic adhesive kind, between the interfacially opposed flexible strip portions in the laminar group and engaging the flexible strip portions in that group so as to damp the longitudinal relative movements of the flexible strip portions in the group when the framework is flexed.
