The seismic isolator also includes a second plate and a low-friction layer positioned between the first and second plates, the low-friction layer allowing the first and second plates to move freely relative to one another along a horizontal plane. The seismic isolator also includes a lower support member attached to the second plate, with a biasing arrangement, such as at least one spring member or at least one engineered elastomeric element, which can include one or more silicon inserts, positioned within the lower support member. The elongate element extends from the first plate at least partially into the lower support member and movement of the elongate element is influenced or controlled by the biasing arrangement. ## Claims ### Claim 1 A sliding seismic isolator, comprising: a first plate configured to be attached to a building support; at least one elongate element extending away from the first plate; a second plate; a low-friction layer positioned between the first and second plates and configured to allow the first and second plates to move relative one another along a horizontal plane when the seismic isolator is in an installed position; a support member attached to the second plate; and at least one biasing element positioned at least partially within the support member, the at least one biasing element having at least one void configured to be filled with a deformable material. ### Claim 2 (depends on 1) The seismic isolator of claim 1, wherein the at least one biasing element comprises a plurality of perforated elastomeric or rubber components. ### Claim 3 (depends on 2) The seismic isolator of claim 2, wherein the plurality of perforated elastomeric or rubber components are arranged in multiple layers. ### Claim 4 (depends on 1) The seismic isolator of claim 1, wherein an end of the at least one elongate element is disposed within the support member and spaced above a bottom wall of the support member when the seismic isolator is in the installed position. ### Claim 5 (depends on 1) The seismic isolator of claim 1, further comprising at least one retaining element configured to couple the at least one biasing element to the at least one elongate element. ### Claim 6 (depends on 1) The seismic isolator of claim 1, wherein the at least one elongate element extends from the first plate at least partially into the support member. ### Claim 7 (depends on 1) The seismic isolator of claim 1, wherein the second plate is located at an upper end of the support member when the seismic isolator is in the installed position. ### Claim 8 (depends on 1) The seismic isolator of claim 1, wherein the deformable material is positioned within the at least one void and comprises silicon. ### Claim 9 (depends on 1) The seismic isolator of claim 1, wherein the at least one biasing element applies a biasing force to the at least one elongate element in a direction parallel to the horizontal plane when the seismic isolator is in the installed position. ### Claim 10 A sliding seismic isolator, comprising: a first plate configured to be attached to a building support; an elongate element extending away from the first plate; a second plate configured to be attached to a foundation of a building; a low-friction layer positioned between the first and second plates and configured to allow the first and second plates to move relative one another along a horizontal plane when the seismic isolator is in an installed position; a support member attached to the second plate; and a biasing element positioned within the support member, the biasing element having at least one void filled with a deformable material. ### Claim 11 (depends on 10) The seismic isolator of claim 10, wherein the biasing element comprises a plurality of perforated elastomeric or rubber components. ### Claim 12 (depends on 11) The seismic isolator of claim 11, wherein the plurality of perforated elastomeric or rubber components are arranged in multiple layers. ### Claim 13 (depends on 10) The seismic isolator of claim 10, wherein an end of the elongate element is disposed within the support member and spaced above a bottom wall of the support member when the seismic isolator is in the installed position. ### Claim 14 (depends on 10) The seismic isolator of claim 10, further comprising at least one retaining element configured to couple the biasing element to the elongate element. ### Claim 15 (depends on 10) The seismic isolator of claim 10, wherein the elongate element extends from the first plate at least partially into the support member. ### Claim 16 (depends on 10) The seismic isolator of claim 10, wherein the second plate is located at an upper end of the support member when the seismic isolator is in the installed position. ### Claim 17 (depends on 10) The seismic isolator of claim 10, wherein the deformable material comprises silicon. ### Claim 18 (depends on 10) The seismic isolator of claim 10, wherein the biasing element applies a biasing force to the elongate element in a direction parallel to the horizontal plane when the seismic isolator is in the installed position.
