Elastic suspension member of plastic material and of the spring or ball and socket type or the like for bed base, mattress or seat

An elastic suspension member made of plastic, and of the spring or ball-and-socket type or the like, for bed base, mattress or seat, said elastic member (1) comprising a base (2) and a head (3) between which an elastic suspension member (4) is interposed, and said elastic member (1) comprising a central longitudinal suspension axis (A), characterized in that said elastic suspension member (4) is made up of three identical or substantially identical elastic structures (5, 6, 7), each formed of at least two rectilinear or substantially rectilinear juxtaposed arms (8), connected together, by pairs, by a hinge (9) in order to form one or more suspension Vs, each active in a suspension plane (P, P′, P″) perpendicular to said hinge (9), said suspension planes (P, P′, P″) of said three elastic structures (5, 6 and 7) intersecting each other at said longitudinal suspension axis (A), and said suspension planes (P, P′, P″) being offset, by pairs, by an angle of about 120°.
