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.

    Un mécanisme de suspension de ciseaux, éventuellement utilisé en tant que base de siège, comprenant un faible encombrement et un élément mobile, un ensemble de deux paires dun premier et dun second bras de ciseaux croisées et un ensemble de liaison comprenant une pluralité dinterfaces de rotation et de liaisons; lesquels sont conçus de telle manière que les premier et second bras de ciseaux croisés décrits, pendant un coup délévation total de lélément mobile par rapport à lélément de base, à la fois à angles positifs et négatifs lun par rapport à lautre tout en passant à travers un angle nul auquel la longueur du mécanisme général est maximale.
