This is' impossible where the leg-supports are coupled with the back-rest and can be adjusted or Ire-adjusted only together with it.
  • the present invention permits to adjust or re-adjust the back-rest and the leg-supports together, as well as independently one from the other, and this effect is rendered possible by the provision ⁇ of a coupling between said members and of another coupling inserted between the leg supports and the mattress frame.

  • the leg-supports are turnable on the pivots 0 and also firmly connected with downwardly directed levers. m.
  • the frame supports also two horizontal transverse shafts f and i.
  • the shaft f is provided with arms g connected with the levers e by rods h, the arrangement being such that if the parts are in the position shown in Figs. 1 and 2 and the shaft f is turned in clockwise direction the rods h and the levers e are moved to the left and the back-rest c is turned from its position of rest (Figs. 1 and 2) into the working position shown in Fig. 3.
  • the arms g and the rods h are connected with each other by pivots g', and .these pivots serve also as means for connecting the arms g with other rods p, the other endsof which are provided with slots g engaged by pins m secured to the free ends of thev levers tm axed to the leg-rests n.
