Device for filtering vibration, and a fixing system comprising a plurality of such devices for fixing a load on a support

Abstract

The invention relates to a vibration-filtering device and to a system for fixing a load on a support by means of a plurality of such devices. The device of the invention for fixing a load on a support comprises: a first fastening zone including fastening means for fastening the device to a support; an arcuate zone; a beam substantially parallel to the first fastening zone; a second fastening zone including fastening means for fastening a load to the device; and at least two spring blades interconnected by an elastomer layer extending through the first fastening zone and the arcuate zone; wherein: the device is a vibration-filtering device; the spring blades interconnected by an elastomer layer pass through the beam to terminate in the second fastening zone close to the fastening means but separated therefrom by respective elastomer layers, in that the spring blades are separated from one another in the first fastening zone for fastening the fastening means on a support by an elastomer layer; and the layer interconnecting the spring blades includes an elastomer having a high damping coefficient, in particular butyl rubber, in particular in the arcuate zone.
