2 Claims. (01. 155-119) This application is a divisional application of my application, Serial Number 661,149 filed Mar. 16, 1933.

The object of the invention is to provide a folding chair for beach or steamer or equivalent use in which a continuous'web constitutes both the seat and back and is anchored at the line defining the juncture at the seat and back, so that no undue strain may be imposed upon it, so that'it may be readily detached from the frame at this point and so that it may be adjusted to increase or diminish the fullness of the seat or of the back; and generally to provide a chair of the kind indicated which is of simple form and susceptible of cheap manufacture.

With this object in view'the invention consists in the construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing wherein:

Figure 1 is a perspective view of the invention in its extended position.

Figure 2 is a sectional view on the plane indlcated by the line 2-2 of Figure 1.

Figure 3 isa persective view of the web and its attendant supporting bars.

The chair is supported on the front and rear legs 10 and 11, the latter being pivotally connected to the former at their upper ends. The rear legs have always a pronounced inclination, when the chair is extended, while the front legs incline slightly from the vertical in the most upright position of the back and increase their inclination as the back is adjusted rearwardly, the planes of the front legs and back being parallel in every instance.

The back comprises the side rails 12 connected at their upper ends with a tie bar 14 and at their lower ends with the cross bar 15, the extremities of which are reduced in diameter to provide protruding studs 16 which are adapted for seating in the notches or seats 1'7 formed in the upper edges of the rear legs which are interconnected at their lower ends with a tie bar 18.

The seat is defined by the side rails 19 which are pivotally connected with the tie bar 20 connecting the front legs at intermediate points in their lengths, these side rails 19 having also pivotal connections with the cross bar 15 beyond which they extend slight distances to be connected by a tie bar 21 which is parallel with but spaced from the cross bar 15 a distance sufficient to permit the passage of a double thickness of the web 22 constituting the seat and back, one extremity of the web being connected to the tie bar 20 and the other to the tie bar 14.

An intermediate portion of the web extends in double thickness through the space between the tie bar 21 and the cross bar 15 and receives in the loop thus formed the lock bar or stick 23, the diameter of which is greater than the spacing between the bars 21 and 15, so that the web is locked at this point and a line of juncture between the seat and back defined.

The front legs at the lower end are connected by the tie rod 24 and arms 25 are provided with 5 pivotal connections with the side rails 12 of the back and also pivotal connections with the front legs 10 in common with the pivotal connections between the latter and the rear legs.

The pivotal connections'of the arms with the side railsof the back are the same distances from the crossbar 15 as the pivotal connections of the arms with the front legs are from the tie bar 20. Similarly, the lengths of the arms as defined by the pivotal connections are the same as the lengths of the side rails 19 of the seat, as defined by their pivotal connections with the tie bar 20 and the cross bar 15. Thus the arms and the side rails of the seat and portions of the front legs and portions of the side rails of the back define parallelograms, whatever the adjustment, and that may be any one of several positions between a substantial upright position of the back and a pronounced rearward inclination of the latter depending on which notches or seats in 3D the rear legs the studs 16 are engaged. By arranging the linkage to define a parallelogram, the most compact position of the elements is secured in the folding operation, this arrangement permitting the front legs to fold down between the rear legs and in edge-abutting engagement with the side rails of the back, the side rails of the seat falling in between the front legs and the arms lying just outside of the rear legs.

By reason of the lock bar or stick, the web at 90 the line of juncture between the seat and back may be readily adjusted to increase or diminish the fullness of either.

A detachable leg rest is provided for use with the chair and this comprises a slatted platform 26, the side rails of which at one end are provided with the hooks 27 for engagement with the tie bar 20 when the chair is extended. The leg rest may have its free end rest on the floor to assume a pronounced inclined position, or it may be elevated above the floor level by extending its legs 28 which are foldably connected with it.

The invention having been described, what is claimed as new and useful is:

1. In a collapsible chair, a back rest portion and a seat portion including strip members held in spaced relationship by elements including cross pieces at the juncture of the back rest portion and seat portion and the opposite end of each. a strip of fabric continuous between the remote ends of the back rest and seat portions, and forming a bite between two cross pieces at the juncture of the back rest and seat portions, a rod, thicker than the space between the last named cross pieces, and enveloped by the bite.

2. A collapsible chair comprising front leg and back rest portions, and arm rest and seat portions, respectively forming opposite sides of a parallelogram pivoted at its corners, and means for supporting the chair when in seating position, the back rest and seat portions including strip members held in spaced relationship by elements including cross pieces at the juncture of the back rest portion and seat portion and at the opposite end of each, a strip of fabric continuous between the remote ends of the back rest and seat portions and forming a bite between two cross pieces at the juncture of the back rest and seat portions, a rod, thicker than the space between the last named cross pieces, and enveloped by the bite.
