  • the hinging of such third cushion to the frame of the piece of furniture involves a structure which is complicated to some extent and a third cushion which is loose makes converting the piece of furniture from one position to the other more difficult.
  • the structure should be simple so that the manufacture of the article is simplified and the need for hardware which becomes troublesome with time is eliminated.
  • a back cushion is preferably firmly connected (fixed) to the frame and a wedge-shaped cushion is provided, which is slidably and pivotally movably guided on the frame for movement from a stowed-away state in the sitting position in which the wedge-cushion is disposed behind the back cushion, to a use state, in the lying position in which it succeeds and adjoins the two cushions lying one behind the other on the carriage.

  • a spring is provided between the upper or rear portion of the frame and the wedge-shaped cushion to assist the sliding and pivotal movement of said wedge-shaped cushion into its stowed-away position.
  • the wedge-shaped cushion is hinged to axles of the rollers or to sliders of the cover at that edge of the wedgeshaped cushion which is the rear lower edge thereof in the stowed-away position.
  • a spring is arranged between the carriage and the frame and is stressed in the position for sitting and in the position for lying.
  • the back cush ion may be firmly connected to the frame of the piece of furniture and behind the back cushion a space may i be left to accommodate the wedge-shaped cushion in its stowed-away position when the piece of furniture is in the sitting position.
  • the shifting of the carriage may be utilized for automatically moving the wedge-shaped cushion into its position for use in the lying position, and its stowed-away position, in the sitting position, because guides are provided.
  • One guide may be originally provided on the frame of the piece of furniture for the cover for the space for bedclothes so that only one additional guide is required, just as in arrangements in which the wedge-shaped cushion is hinged to the carriage. Said conversion can be performed without a great effort and the effort required may be further re depictd if springs are provided which assist the initiation of the conversion movements.
