  • Publication number: 20120007295
    Abstract: An isolation mount for supporting and isolating one part from another includes an inner member formed to be connected to one of the parts and an outer member formed to be connected to one of the parts. The inner member has a first and a second inner plates being connected at one end and extending at a first angle with respect to each other; the outer member also has a first and a second outer plates being connected at one end and extending at a second angle with respect to each other. The isolation mount further includes a first and a second individual elastomeric element compressed between respective inner and outer plates.
