FOLDING CHAIR Application filed May 9,.

again be folded upon manipulation of the seat.

This object is accomplished by the construction illustrated in the accompanying drawings, in which s Fig. 1 is a side elevation of a structure embodying the invention; and

Fig. 2 is a. front elevation projected from Fig. 1.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

The invention comprises a frame-1 having parallel legs 2 spaced apart and connected near their lower ends by a cross-brace 3. A transverse rod 4 is secured in the legs at points approximately midway between the top and bottom of the frame and affords pivotal support'for a folding seat 5 through which the rod extends.

A pair of folding legs 6 are pivotally secured on the rod 4 respectively between the corresponding sides of the seat and the legs 2 of the frame, the lower parts of the legs 6 being connected together by a transverse rod 7. Also, a cross-brace 8 is connected with its upper arms pivoted on the rod 4 between the sides 5, and with its lower arms pivoted on the rod 7 so that lateral movement of the folding legs relative to the frame is prevented.

To each leg 2 of the frame upon its inner side at a point above the seat supporting rod 4 is pivotally secured an arm 9, as indicated by 10, the lower end of the arm being connected with the rod 7 by means of a link 11, which acts to limit the spread of the frame and its folding legs. The arms 9 are connected together by a transverse bar 12 at a point thereonimmediately above the top of the seat and serves as a stop to limit the upward movement of the rear end of the seat when the seat reaches its horizontal position.

At each side of the seat is a link 13 that is pivoted at one end of the seat at a point thereon between the supporting rod 4 and the rear end of the seat, said link being pivoted at its opposite end to the corresponding arm 9 at a point thereon below a plane ex- 1925. Serial, No. 29,025.

tending through its other pivotalconnection I and the seat rod 4 when the chair is in position for use.

A back-rest 14 preferably formed of a sheet of wood veneer of suificient thinness as to admit of flexure, is secured rigidly at its top to the frame and at its bottom to the bar 12, therebeing also a cross-brace 15 in the frame back of the rest 14 for its support.

In utilizing the invention, when the seat is in extended position for use, the arms 9 are held in extended position by the links 13 while the rear end of the seat bears upwardly against the cross-bar 12. The folding rear legs are held in their extended position by the arms 9 through the medium of the links 11. Also, the back-rest is bent by the movement of its lower end as the arms 9 and cross-bar 12 are swung rearwardly so that the back presents forward curvature to approximately fit the back of the occupant When the seat is in horizontal position the arms 9 and the folding legs 6 connected therewith are locked against having foldin movement by the links 13, and movement 0 the links 13 is dependent upon tilting of the seat.

The chair is folded by lifting the front end of the seatand swinging it into the frame which has the effect of moving the legs 13 out of locking position and imparting folding movement to the swinging arms 9 and the legs connected therewith.

What I claim is 1. A folding chair including a frame having spaced parallel legs; a transversely disposed supporting rod connecting the legs; folding leg members having pivotal connection at their upper ends on the rod; a tilting seat pivoted on the supporting rod; a pair of arms pivoted in the frame at a point therein above the supporting rod and having linked connections respectively at their lower ends with the corresponding folding legs; a cross-bar connecting said arms and operable to limit tilting movement of the seat in one direction; a flexible pack having fixed connection at its upper end in said frame and at its lower end with said cross-bar; and a link connection between each side of the seat and the corresponding arm operable to prevent movement of said arms when the seat is in position for use.

2. A folding chair including a frame having a pair of fixed legs spaced apart and a transverse seat supporting rod; a seat pivsaid folding legs; and a, link oonnectionvbetween said seat, back of the supporting rod,

and swinging. member operable tolock the swinging member from having folding movement when the seat-is positioned for use,

In testimony whereof I aflix my signature.

WILLIAM C. RASTETTER.
