RECLINING CHAIR Filed 12. 1956 2 Sheets-Sheet 2 INVENTOR: Ga -Z021 LoreflZ United States Patent 7 2,894,564 RECLINING CHAIR Anton Lorenz, Boynton Beach, Fla.
Application October 12, 1956, Serial No. 615,526 8 Claims. (c1. 155-117 This invention relates to chairs of the type in which in Fig. 2. Near the rear end of the side rails 25 of the seat, grooves 28 are provided which face toward the center of the chair as shown in Fig. 3 and wear plates 30 are secured in the bottoms of these grooves or recesses.
,' 32 represents the back rest of the chair which has side 1' rails 33 which are connected with each other at their the seat and the back may be moved to and from a sitting position into a reclining position.
Chairs of this type have generally been so made that when the back of the chair is inclined rearwardly, the seat is either left in a horizontal position or is inclined into another position, neither of which are comfortable to the user of the chair. Consequently it is an object of this invention to provide a construction for chairs of this type in which the seat of the chair is so connected with the back of the chair that the seat in each position of the back will be so arranged as to provide the utmost comfort for the user. It is also an object of this invention to provide a chair of this kind which may also be folded to occupy a compact space. A further object is to provide a chair of this type which is provided with upper ends, for example by means of slats 34 or other suitable means. The side rails of the back are spaced closer together than the side rails of the seat and consequently the lower portions of these rails fit between the side rails of the seat. At the lower ends of the back rest the side rails are pivoted at 36 on the blocks 20 of the rear legs 12 of the chair below and in rear of the pivots or hinges 27 connecting the seat with the rear legs. The side rails 33 of the back rest are connected by means of a cross piece 38 which also extends outwardly beyond the a foot rest which is moved into a foot supporting position when the back of the chair is inclined rearwardly and which is moved into an inoperative position frame when the back of the chair is swung forwardly into a substantially vertical position.
Other objects and advantages of this invention will appear in the following description and claims.
In the accompanying drawings: 7

Fig. 2 is a side view thereof when folded.
Fig. 3 is a top plan view thereof with the parts 8.1" ranged in seating position and partly cut away to show lower parts of the chair.
Fig. 4 is a fragmentary perspective view of one of the rearwardly extending rails'of the chair seat.
.Fig. 5 is a perspective view thereof. 7
Referring to the drawings in Which my invention is shown as applied to a folding type of chair, this chair has front legs 11 and rear legs 12 which together with the front legs form the base of the chair. The two front legs 11 are connected with each other by means of cross members 13 and 14. The front and rear legs are connected with each other by means of hinges 15 which are preferably secured to the cross piece 14 of the front legs 11. The rear legs are spaced apart a shorter distance than the front legs so that the rear legs may fit between the front legs 11 when the chair is folded about the hinges 15 as shown in Fig. 2. The swinging of the front legs relatively to the rear legs is limited by means of a pair of pivotally connected links 16. One link of each pair has one end pivotally connected with a front leg of the chair and the other link of the pair has one end pivotally connected to a rear leg. The other ends of the links are pivotally connected with each other at 17. These links swing toward each other when the legs are moved into folding position and the links then enter into recesses 18 and 19 formed in the legs of the chair. The rear legs each have blocks 20 secured to the inner faces thereof and extend rearwardly therefrom and these blocks are connected by a cross piece 21 shown in Figs. 2 and 5.
The seat shown, by way of example, has rails 25 at sides of the rails 33 of the back rest. The ends of the cross piece 38 extend into the grooves 28 of the seat rails 25, and are slida'ble therein. To reduce the wear on the cross piece, wear plates 39 are preferably secured to the ends of the cross piece 38 in position to cooperate with the wear pieces 30. These wear pieces 30 and 39 reduce the friction which results when the seat 32 is moved about its pivot 36 and the wear on these contacting parts.
The normal sitting position of the seat and the back rest is shown in full lines in Fig. 1; and if a person leans backward, the back rest is tilted into the position shown in broken lines in Fig. 1 and this results in the movement of the seat into the inclined position also shown in broken lines. During the swinging of the back rest from the fullline position to the broken line position in Fig. l, the arc of movement of the ends of the crosspiece 38 about the pivot or hinge 36 when the back rest is swung rearwardly will cause the rear ends of the rails 25 of the seat to swing downwardly thus causing the seat to swing about its pivots 27. The seat will occupy an inclined position with the front end thereof higher than the rear which is the position which is most comfortable to users. It will be noted that the ends of the grooves 28 terminate in shoulders which form stops with which the ends of the cross piece 38 engage for limiting the extent to which the chair back and seat may move into normal sitting or inclined positions. Consequently the length of the grooves 23 determines the extent to which the back of the chair may swing rearwardly into reclining position and to the extent to which the chair seat may swing.
When the chair is to be folded, the pivotally connected ends of the links 16 are moved downwardly whereupon the rear legs 12 may be swung between the front legs, as is common practice with folding chains. When the rear legs are swung toward the front legs, the pivots 27 are swung downwardly, thus swinging the rear end of the seat downwardly, so that the recesses 28 are swung away from the ends of the crossbar 38. This makes it possible to swing the back and seat toward each other as shown in Fig. 2. However, when the chair is again unfolded the ends of the cross bar 38 again enter the recesses 28 and limit the swinging of the back relatively to the seat.
It will be obvious that the relative movement of the back and seat as stated in the foregoing description is not limited for use only on folding chairs since the mechanism described can be used on chairs of other kinds, such for example as chairs with stationary frames or bases on which the tilting back rest and seat may be mounted to move from a sitting position into a semireolined or tilting position. i
It will be understood that various changes in the details, materials and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art, within the principle and scope of the invention, as expressed in the appended claims.
