Abstract
A mount with a first attachment member; a second attachment member spaced from the first attachment member; and resilient members joining the first and second attachment members, each of the resilient members having at least one void, the 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 voids are substantially closed, the mount having a second substantially constant stiffness when the voids are in the second collapsed condition.
Claims8
A mount comprising:
- a first attachment member;
- a second attachment member spaced from the first attachment member;
- and a plurality of discrete resilient members joining the first and second attachment members, each of the discrete resilient members including a plurality of voids, said 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 said voids are substantially closed, the mount having a second substantially constant stiffness when said voids are in the second condition, the voids of each discrete resilient member having substantially the same cross sectional area, the cross sectional area of the voids of each discrete resilient member being different than the cross sectional areas of the voids of the other discrete resilient members.
A mount comprising:
- a first attachment member;
- a second attachment member spaced from the first attachment member;
- and a plurality of adjacent resilient members joining the first and second attachment members, each of said resilient members including at least one void, said void being substantially collapsed when a load having a predetermined threshold magnitude is applied to either the first or second attachment member and said at least one void being uncollapsed when a load having a magnitude less than the threshold magnitude is applied to either the first or second attachment member wherein the mount comprises an axial direction, the axial dimension of each resilient member being different, each pair of adjacent resilient members being separated by a shim member.
