(54) Adjustable spiral mattress supporting base with trapping safeguard


(57) A spiral mattress supporting base comprises a fixed lower frame (1) and an upper frame (2) which is mounted directly upon the fixed lower frame (1) and which comprises movable upper frame members (4-6). The upper frame (2) has upper longitudinal sections (11-13, 20) and traverse members (14, 15) extending transversely between the longitudinal sections, between which upper longitudinal sections (11-13, 20) a network (24) of interlocked helical springs is spanned. The lower frame (1) has lower longitudinal sections (16). The transverse distance between the lower longitudinal sections (16) is smaller than the transverse distance between the upper longitudinal sections (11-13, 20).
