Abstract
An antiseismic support pad having a base for supporting and holding the pad on a support surface, at least one spherical rolling element mounted to rotate freely about a center of rotation in a bearing secured to the support base, and a support plate resting on the spherical rolling element via a concave bearing surface, the pad being characterized by the fact that the support base comprises a soleplate secured to at least one bearing, configured to rest freely on the support surface and to hold the pad in place on the support surface without a fastener, and that the support pad includes an arrangement configured to suspend the support base from the support plate and move the base resiliently in radial directions about a support plate axis that is substantially perpendicular to the soleplate, the arrangement connected firstly to the support plate and secondly to the support base comprising the soleplate and the bearing.
