No. 225,259 1 Claim. (Cl. 297-642) This invention relates to reclining seating devices and to seating mechanisms therefor. It is particularly directed to mechanism for chairs, rockers, or other seating device which can be used either in a sitting position or in any of a multiplicity of reclining positions.
An object of this invention is to provide, in a device of the character described, linkage so designed that by pressing or leaning against the back of the chair, causing the back to rotate rearward on its pivot, the seat is moved upward and forward to a reclined chair position, the angle between the seat and back being determined by the amount of rearward rotation of the back. The linkage may be returned to its original sitting position by applying pressure rearwardly on the seat. The linkage has also been designed so that the weight of the occupant on the seat counterbalances the pressure against the back, permitting the chair to remain in a reclined position without use of friction device or counterbalancing springs. The linkage is further balanced to maintain its normal sitting position and will recline only when pressure is exerted against the upper portion of the back.
The mechanism includes a four-bar linkage for supporting and moving the seat, a fixed pivot about which the back rotates, and a connecting and balancing link to actuate back and seat simultaneously. 7
Another object of this invention is to provide a strong, rugged and durable device of the character described which shall be relatively inexpensive to manufacture, comfortable in use, smooth in operation, and practical and efiicient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.

3,l%,5?h Patented Aug. 3, i965 "ice verse or cross member 17 located above curved part 14, and by a vertical transverse or cross member 13 located at the front edge of cross member 17.
The base 12 may also comprise side members 2% interconnected by transverse cross members 21. The curved rails 14 contact thefiat surfaces 15 which are at the upper ends of side base members 20.
The side members 16 may extend upwardly and include side arms 24 for the chair. Fixed to the inner sides of the side members 1%, above the cross members l7, 13 are opposed, horizontal fixed mounting links 3% attached to said members by rivets, bolts or other attaching means 33. In the drawing, the supporting means for one side only of a seat rail 32 and a back rail 33 are illustrated, it being understood that the supports for said rails on opposite sides of the chair are similar and symmetrically disposed about a vertical plane at the middle of the chair and parallel to members 16. The mechanism on one side only will be described. Seat rail .32 comprises parallel side members 34 interconnected by a rear transverse member 35 and an inclined front transverse member 35. The back rail 33 comprises parallel side members 3'7 interconnected by a transverse member 38. Parallel members 37 may be in the planes of parallel members 34, as seen in FIG. 2 of the drawing. The seat and back rails are located between members 16.
When the chair is in sitting position, the seat rail 32 may be somewhat upwardly and forwardly inclined from horizontal, as shown in PEG. 1, whereas the back rail 33 is somewhat upwardly and rearwardly inclined from ver- Also the back rail 33 is located above and at the rear end of the seat rail, in the sitting position illustrated in FIG. 1.
The seat and back rails when upholstered comprise the seat and back of the rocker or chair.
The side portions 34 and 37 of the seat and back rail are spaced inwardly away from the walls 16, as shown in FIG. 2. The fixed mounting links 30 contact the inner surfaces of side walls 16.
Pivoted to the inner sides of links St at the front ends of the latter, by means of pivot pins ll are front seat carrier links 4-1 which incline upwardly and rearwardly. Pivoted to rear ends of links 39, as at 42, are rearwardly and upwardly inclined rear seat carrier links 43 which may be somewhat longer than links 41. The upper ends of links 41, 43 are offset inwardly, and pivotally connected by means of pivot pins 44, 45 respectively, to a seat mounting link 46 which is fixed, as by rivets, belts or the like fasteners 47, to the outside of side walls 34 of the seat rail 32. The seat mounting links 46 run parallel to the walls 34. Each seat mounting link 46 has a rear extension 48 projecting rearwardly of pivot pin 45 and is located beneath the lower end of the back rail 33.
Pivoted to the rear ends of extensions 48 of seat mounting links 46, as by pivots 59, are short connecting links 51 which incline forwardly and upwardly and are located in spaced outer relation to the seat mounting link.
Fixed to the inside of each side wall 16, above the seat rail, is a fixed pivot bracket 6t). Each bracket all has upper and lower flanges 61 contacting the inner surface of wall 16, and fixed thereto by rivets, bolts or the like fastening elements 62. Flanges 1 are interconnected by an inwardly offset channel or web 63 having a wall 64 parallel to and spaced inwardly from wall 16. Wall 64- is formed with a keyhole or slot 65 having a larger upper end 66 and a lower downwardly extending narrow slot portion'67 having a lower semi-circular edge 63. Wall 64 is spaced outwardly of wall 37 of the back rail 33.
Fixed to the outer side of each wall 37, is a back mounting link 70. Link 7t is fixed to wall 37 by rivets, bolts or other fasteners 71. The lower end 72 of link 71 is offset outwardly, and is located in a plane between the planes of links 51 and walls 16. Said lower end 72 is pivoted as at 73, to the upper end of link 51. Back mounting link 70 inclines downwardly and forwardly.
Fixed to the upper end of each link 70 is a horizontal pivot pin 75 projecting outwardly and provided with a shank 76 and a flanged outer head 77. The shank 76 of pivot pin 75 is received in slot 67 and rotatably contacts semi-circular edge 68. The head 77 may pass through the enlarged upper end 66 of hole 65 to facilitate the assembly.
The back rail 33 is thus pivoted to the support 13. By pressing or leaning against the back 33 of the chair, causing the back to rotate rearward on its pivot 75, the seat 32 is moved upward and forward to the reclining position of the chair, the angle between the seat and back being determined by the amount of rearward rotation of the back.
The linkage may be returned to its original chair sitting position by applying pressure rearwardly on the seat.
It will be noted that the linkage is so arranged that the Weight of the occupant on the seat counterbalances the pressure against the back, permitting the chair to remain in any reclined position without use of special friction devices or counterbalancing springs; The linkage is also balanced to maintain its normal sitting position and will recline only when pressure is exerted against the upper portion of the back.
The front end 80 of the seat rail 32 may be T-shapecl with side extensions to contact the front edges 81 of side walls 16 to stop the parts in sitting position. Also a stop pin 82 may be fixed to a front upward extension 83 on the fixed mounting link 30 to limit the movement of the parts toward fully reclining position by contact with the forward edge of front carrier link 41. Another stop pin 84 may be fixed to the fixed mounting link 30 to contact the rear edge of front carrier link 41 to stop movement of the parts toward sitting position of the chair, if the seat is not T-shaped at its front end.
It-Will be noted that the fixed pivot brackets 60 could be fixed to or be made integral with the fixed mounting links 30, if desired.
It will thus be seen that there is provided an apparatus in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.
As possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
