ABSTRACT:
An antivibration support has two rigid strength members interconnected by an elastomer body having both a bell-shaped side wall and a central leg extending inside the side wall from the top of the elastomer body to a baseplate secured to one of the two strength members. The side wall has an aspect ratio lying in the range 2 to 8, while the central leg has an aspect ratio of less than 2, such that when a predetermined static axial load is applied to the support, the side wall is subjected to buckling and then presents substantially zero stiffness while the central leg is not subject to buckling.
