An object of the invention is to provide an improved link system for this type of articles of repose.

Another object of the invention is to provide means for controlling the movements of the leg-rest swingably mounted on the seat of such an article of repose.

A further object of the invention is to improve on the construction of articles of repose as now customarily made.

Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanying drawings forming part of this specification, wherein:

Fig. 1 is a side elevational view of a reclining chair according to the invention, a portion of a side frame being broken away,

Fig. 2 is a side elevational view of the reclining chair shown in Fig. 1, wherein however the movable members of the chair are in the extreme reclined position,

Fig. 3 is a side elevational View of another embodiment of a reclining chai according to the invention, a portion of a side frame being broken away,

Fig. 4 is a side elevational view of a further embodiment of a reclining chair according to the invention, a portion of a side frame being broken away,

Fig. 5 is a side elevational view of still another embodiment of the chair according to the invention, a portion of a side frame being broken away, and

Fig. 6 is a side elevational view of a further embodiment of a reclining chair according to the invention, a portion of a side frame being broken away.

Referring now to Figs. 1 and 2, 19 generally indicates a support comprising

side frames

12 and 14 connected with each other by a cross bar 16.

The lower end of a backrest 18 is swingably mounted on the support 19 at 29. The rear end portion of a seat 22 is pivoted to said back-rest 18 at 24 at a point above the pivotal connection 25 between the back-rest 18 and the support 10.

A controlling element 26 in the shape of a bell-crank lever is swingably mounted on the support at 28. The upper arm 30 of said controlling element 26 is pivoted at 32 to the front end portion of a connecting link or arm-rest 34. The rear end portion of said connecting link 34 is pivoted to the back-rest 18 at 36 at a point above the pivotal connection 24 between the back-rest 18 and the seat 22. The lower arm 38 of the controlling element 26 is pivoted at 4-1) to the lower end of a link 42, the upper end of which is pivoted to the seat 22 at 44 A leg-rest es swingably mounted on the front end portion of the seat 22 at 43 is pivoted to the front end of a controlling link 50 at 52. The rear end of said controlling link 50 is pivoted at 54 to the lower end of an arm 56 "ice swingably mounted on the seat 22 at 58. One end of a link 60 is pivoted to said arm 56 at 62, the other end of said link 60 is pivoted to the lower arm 38 of the controlling element 26 at 40 in coaxial alignment with the pivotal connection between said lower arm 38 and the link 42.

When the back-rest 18 is moved from the sitting position, shown in Fig. 1, into the reclined position 18, shown in Fig. 2, the seat and the leg-rest are brought into the positions 22' and 46 respectively by means of above described link system.

The sitting position of the movable members of the chair, shown in Fig. 1, is limited by a stop 64 arranged on the support for abutting cooperation with the seat 22. The extreme reclined position of the movable members of the chair, shown in Fig. 2, is limited by another stop 66 arranged on the support for abutting cooperation with the lower end of the back-rest 18.

According to the embodiment shown in Fig. 3, again the back-rest 118 is swingably mounted on the support 11th at 12% and the rear end of the seat 122 is pivoted to the back-rest 113 at 1124 at a point above the pivot of the hack-rest 318. Furthermore, again the controlling element 126 swingahly mounted on the support 11% at 1'28 is controlled by the connecting link 134 pivoted to the upper arm 13% of the controlling element 126 and to the back-rest 118 at the

points

132 and 136 respectively.

The controlling mechanism for the seat 122 however is different. According to Fig. 3, an arm 163 is swingably mounted on the support lit} at 176. A link 172 is pivoted at dilferent regions thereof to the lower arm 138 of the controlling element 126 at 14-1 and to said swingable arm 168 at 174. The seat 122 is pivoted to the upper end of a link 143 at 144. The lower end of said link 143 is pivoted to the swingable arm 168 at 176.

The leg-rest 146 swingably mounted on the front portion or" the seat 122 at 143 is pivoted to one end of the controlling link 15%? at 152. The other end of said controlling link 15% is pivoted to the swingable arm 168 at 155.

The sitting position of the movable members of the chair, shown in full lines, is limited by the stop 164 and the extreme reclined position of the movable members of the chair, shown in dash-and-dot lines, is limited by the stop 166.

According to the embodiment shown in Fig. 4, the backrest 218 swingably mounted on the support 214) at 22% is pivoted to the rear end of the seat 222 at 224 and to the rear end of the connecting link 234 at 236. The upper arm 23d of the controlling element 226 swingably mounted on the support 21% at 228 is pivoted to the connecting link 23% at 232. The lower arm 238 of said controlling element 226 is pivoted at 24-1 to one end of the link 272. The other end of said link 272 is pivoted at 274 to an arm 268 swingably mounted on the support at 276). Said swingable arm 268 has an extension 278 rigid therewith. A roller 2% rotatably mounted on said extension 278 is in movable abutting engagement with the lower surface of the seat 222.

The leg-rest 246 swingably mounted on the front portion of the seat 222 at 243 is pivoted at 252 to one end of the controlling link 25%. The other end of said controlling link 259 is pivoted at 255 to the swingable arm 268.

The sitting position of the movable members of the chair, shown in full lines, is limited by a stop 264 arranged on the support 216. The extreme reclined position of the movable members of the chair, shown in dash-and-dot lines, is limited by a stop 266 also arranged on the support 210.

7 According to the embodiment shown in Fig. 5, again Patented Mar. 18, 1958 th'e'vlowe'r end of the back-rest 3-18 is swin gably mounted on the support 310 at 320. The rearend portion of the 7 seat 322 is pivoted to the back-rest 318 at 324 at a point above the-1 pivotal connection320 of the back-rest suppoft lil fl at 32'8 is pivoted to the connecting link- 334 5 55332.; The lewe'r am 333 or said controlling element 326 carries; a roller 382' being in abutting engagement an arnr 368 swingably mounted on the support 310 at37 0. A link 343 is pivoted at different regions thereof to said swihg'a'hle arm 3 68 at 376 and to the seat 322 at 344i The controlling link 350 is pivoted at difierent regions thereof tosai'd swingable arm 363 at 355 and to leg-rest- 346 at 352. The leg-rest 346 is swingably riiou-nfedon the front portion-of the seat 322- at 343.

Th sitting position of the movable members of the chair, shown in full linesgis' limited by the stop 364 and the extreme rec lin'e'd position of the movable members store ehair, shown in dash-and-dot lines, islimited by the step 366.- v
