Abstract
A scissor suspension mechanism, optionally used as a seat base, comprising both small footprint base and movable element, a set of two pairs of crossed first and second scissor arms and a linkage assembly including a plurality of pivot interfaces and linkages; which are designed in a way that the crossed first and second scissor arms describe, during the total elevation stroke of the movable element with respect to the base element, both positive and negative angles with respect to each other while passing through a null angle at which the overall mechanism length is maximal.
