Definitions

  • the present invention relates to new improvements in adjustable reclining chairs. More particularly, the invention relates to that type of reclining chairs in which a back rest, a seat part, and a leg-supporting part are pivotably mounted'on a stationary frame by means of fittings and also to each other so that, .when a person reposes in the chair, a change in the inclination of his body by leaning forwardly or toward the rear will also change the angularity of the individual parts of the chair relative to. each other and tothe stationary frame.
  • this brace member willsp'ositively pivot the leg-supportmgpar't upwardly toward a-substan either by inclining the upper bodymore forwardly or,
  • Fig. 2 illustrates a similar view oflt-he chair in the reclining position
  • i Fig. .3 illustratesa view' similar to Fig lof a'-:slightly modified embodiment of the invention
  • 1 i Fig. 4 illustrates a side view of the chair according to Fig. 3 in the reclining position.
  • a V V T Referring to the drawings, and. first particularly to Figs. 1 and 2, the stationary frame part of the chair consists' of a pair of side parts with armrest L'chair legs 2,side Walls S-connectingfithe front and rearlegs to each other,
  • the movable parts ofthe chair consisting-0f the v back rest 6, and the 7,and-theleg support. 8 are con-1f j i nected to eachother-by hinges Qandlll, respectively.
  • crossbar 'Hinge 1-1 ismounted in such a position that its'pivotal axis is disposed vertically underneath the center'of gr'avityof a person reclining in the chair.
  • crossbar '4 carries abracket 13 with a pin 12 thereon which. extends into aslot Mina plate.15which is secured by screws to the respective side member of the frame of seati.
  • pins 12 are preferably provided with rollers.
  • the same pins 12 also serve as pivots on which a pair of straps 16 are mounted at one end, while the otherend of each strap 16 is pivotably connected to the leg support 8 at a point spaced from hinge I'll, Straps 16 are designed so as to pivot the leg support 8 upwardly. toward a substantially horizontal position during the combined backward and elevating movement of seat 7.”
  • saidiipin-andframe may also be downwardly extended and provided with such slots.
  • leg support 8 according to the embodiment of the invention as illustrated in Figs. 1 and 2 is pivotably mounted on the movable seat 7 and the stationary side walls 3 of the chair so as to depend vertically downward when the chair is in the sitting position as shown in Fig. 1, the modification of the inventon as illustrated in Figs. 3 and 4 shows the leg support 8 to be tiltable underneath the seat so as to practically be unnoticeable when the chair is in the sitting position. T his may be attained by mounting hinge 10 on the lower edges of the leg support 8 and the frame of seat 7 rather than on the upper edges thereof, as shown in Figs. 1 and 2.
  • a tension spring 17 is connected at one end to the stationary crossbar 4 of the seat frame and at the other end to the downward extension of the back rest 6 at a point intermediate the pivotal axis 11 and the hinge 9.
  • This spring 17 counteracts the force which is exerted upon back rest 6 when a person sitting in the chair leans backwardly and compensates the weight displacement in cooperation with the weight of the legs which then lie on foot support 8, which is tilted forwardly and upwardly up to a substantially horizontal position.
  • the seat of the chair may also be guided and suspended in a manner different from that above described, provided the seat will always be positively guided during the movement so that the pivotal movement of the back of the chair will always be accompanied by the desired change in the position of the seat.
  • An adjustable reclining chair comprising a stationary frame, a back rest, a seat part, and a leg-supporting part, means for pivotably connecting said seat and leg-supporting parts to each other at their adjacent ends, means for pivotably connecting the other end of said seat part to said back rest at a point above its lower end, means for pivotably connecting said back rest near its lower end to said stationary frame so as to form a one armed lever, said lever being adapted to pivot about an axis disposed substantially vertically underneath a point where the center of gravity of a person would be located when reposing on said chair, a slide member secured to said seat part, at least one stationary member on said frame engaging with said slide member to permit the latter to slide relative to said stationary member and to be guided thereby so that at a pivotal movement of said back rest about its axis said seat part will not only move forwardly and backwardly with said back rest but will also change in its angular position relative to said back rest, and at least one member pivotably mounted at one end on said frame at-a point substantially co
  • said means for pivotably connecting said seat and leg-supporting parts comprise at least one hinge mounted on the adjacent lower edges of said parts, and a tension spring connected at one end to said frame at a point near said stationary member and at the other end to said back rest at a point intermediate said axis thereof and said means for pivotably connecting said seat part to said back rest.
  • said slide member comprises a pair of plates secured to each side of said seat part, each of said plates having a curved slot therein, said stationary member comprising a pair of pins mounted on said frame, each of said pins engaging into one of said slots.
  • said seat part comprises a frame, said slide member being integrally screwed to said seat frame and having at least one curved slot therein, said stationary mem ber comprising at least one pin mounted on said stationary frame and engaging into said slot.
  • An adjustable reclining chair comprising a stationary frame, a back rest, .a seat part and a leg-supporting part interlinked with each other, means'for tiltably supporting said back rest at apoint on the frame, each side of said frame fixedly supporting pivot means, a slotted guide member secured to said seat part and slidably receiving said pivot means, a linking lever interconnecting said pivot means and said leg-supporting part, said linking lever and said slotted guide member being movable with respect to said pivot means.
