Mount with dual stiffness

Abstract

A mount comprising a first attachment member; a second attachment member spaced from the first attachment member; and at least one resilient member joining the first and second attachment members, each of the at least one resilient members comprising at least one void, each of said at least one voids being collapsible under loading between a first open void condition where the mount has a first substantially constant stiffness, and a second collapsed condition where the at least one void is substantially closed, the mount having a second substantially constant stiffness when each of the at least one void is in the second collapsed condition.
