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 armchair according to the invention, a portion of a side frame being broken away,

Fig. 2 is a side elevational view of another embodiment of a reclining armchair according to the invention, a portion of a side frame being broken away,

Fig. 3 is a side elevational view of a further'embodiment of a reclining armchair according to the invention, a portion of a side frame being broken away,

Fig. 4 is a side elevational vew of still another embodiment of a reclining armchair according to the invention, a portion of a side frame being broken away,

Fig. 5 is a side elevational view of a further embodiment of a reclining armchair according to the invention, a portion of a side frame being broken away, and

Fig. 6 is a side elevational vew of still another embodiment of a reclining armchair'according to the invention, a portion of a side frame being broken away.

*Refe'rringnow to Fig. 1, 10 generally'indicates a support comprising side frames 12 and 14 connected with each other by cross bars 16.

The lower end of a back-rest 18- is swingably mounted onthe support 10 at 20. The rear endportion of a seat 22 is pivoted to the back-rest 18 at'24 at a point above the plane of the pivotal connection between the back-rest 18 and the. support 10.

-A controlling element 26 in the shape" of a doublearmed lever is swingably mounted on the support 10 at 28. 1 The upper arm 30 of said double-armed controlling element 26 is pivoted at 32 toone end of a connecting link 34; The other end of said connecting link 34 is pivoted to the back-rest 18 at 36 at a point below the pivotal connection 24 between the back-rest 18 and the seat 22.

The lower arm 38 of the double-armed controlling element 26 is pivoted at 40 to an element 42 in the shape of a link 44 having a lateral extension 46. The upper end of the link 44 is pivoted at 48 to the-seat 22.

Furthermore a leg-rest 50 swingably mounted on the ice A 2 front portion of the seat 22 at 52 is pivoted at 54 to the upper end of a controlling link 56. The lower end of said controlling link 56 is pivoted at 58 to the extension 46 of the link 44.

The sitting position of the movable members of the chair limited by a stop 60 arranged on the support 10 for cooperation with the lower surface of the seat 22 is shown in full lines. When the back-rest 18 is swung into a reclined position, for example into the extreme reclined position 18' shown in dash and dot lines, limited by the rear wall 62 of the support 10, the above described link system causes. a movement of the seat and the legrest into the positions 22 and 50, respectively.
