An isolator mount system includes multiple isolator mounts that are used to isolate a piece of equipment from a structure. The isolation mounts each include an isolation pad between inner and outer mountings, to provide damping between relative motions of the inner mounting and the outer mounting. A central portion of the isolation pad is closer to a central axis of the isolation mount than are ends of the isolation pad that are on opposite sides of the central portion. This configuration provides two shear sections, to provide additional damping, an additional amount of shear in the isolator mounts. The shear sections may be configured to control location of the center of elasticity of the system, for example by locating the center of elasticity at the same location as the center of gravity of the system, thereby resulting in an isoelastic system.

The invention relates to a hollow spring element of which the outer surface has at least one peripheral notch, which has at its base a notch geometry with a radius of curvature of less than 1 mm.

A dampener assembly dampens vibrations between a first member and a second member. The bumper comprises a cellular material defining a plurality of cells. The bumper has a mounting surface wherein a portion of the plurality of cells are open at the mounting surface. The dampener assembly also includes an overmolded bracket comprising a polymeric material. The overmolded bracket has a body portion extending between a first bracket end and a second bracket end. The body portion has an attachment surface configured to couple to the first member. The body portion also has a bonding surface opposite the attachment surface with the bonding surface coupled to the bumper. The polymeric material of the overmolded bracket is disposed within the open cells at the mounting surface of the bumper for bonding the overmolded bracket and the bumper to one another.

An anti-vibration device including first and second rigid strength members interconnected by an elastomer body, the first strength member includes a base and at least three branches extending from the base along a first direction toward the second strength member, the three branches including two external branches and one central branch. The second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member. The elastomer body extends transversally to the first direction between the external branches of the first strength member and has four legs extending respectively between the branches of the first strength member and the branches of the second strength member.

These teachings relate to a device that includes a base having an axis that is centered and perpendicular relative to the base and two or more arms each connected to the base at a base hinge The base hinge rotates the two or more arms away from the axis, and one or more expandable bands are connected with distal ends of the two or more arms. The one or more expandable bands absorb energy from rotating of the two or more arms. The device absorbs energy when an external force is applied along the axis of the base.

Implementation described and claimed herein include a cushioning structure and method for manufacturing a cellular cushioning system, which allows for maximum comfort through the compression and shock cycle. Specifically, a cushioning structure comprises void cells formed in an array, which comprise multiple outwardly curved surfaces, with varying radius measurements. Stiffness in the void cells can vary by varying the Radii. Outwardly curved surfaces prevent buckling and provide support for high impact by absorbing energy.
