Apr. 24, 1923. 1,452,869 R. E. cATrlER PORTABLE FOLDING SEAT Filed Jan. so, 1922 2 sheets-sheet 2 Patented Apr. 24, i923.



Application filed January 30,' 1922.

To all whom t may concern Be it known that I, RAYMOND EUGNE Ca'rrrnn, a citizen of the French Republic, residing at 106 Avenue de Versailles, Paris, France, have invented certain new and useful Improvements in Portable Folding Seats, of which the following is a specification.

The present invention relates to portable folding seats, and consists of a particular arrangement, noteworthy forl its strength, its restricted bulk and the comfortable positions which it provides forl the body of a person when resting on it.

rl`his arrangement consists essentially of a trestle provided with a. hinge o-r joint which permits the two surfaces of the trestle to assume a more or less accentuated inclination, one of these surfaces forming the.

back being itself articulated at its base or foot to a low plate slightly raised above the ground by any suitable means, such as small foot pieces or the like. This plate formingl the seat proper can be replaced by any flexible surface such as leather, woven material, india rubber, basket-work or the like, placed directly on the ground; by reason of the weight of the body resting thereon it maintains in place the back portion which also rests on the ground by the second surface of the trestle. These three surfaces, seat, back and support, of suitable shape and outline, thus jointed one to the other, can be folded one against the others, or one between the others for transport; they can be formed of any appropriate material, such as wood or metal, solid or perforated, or consist of frames which may if desired be covered,

upholstered or fitted, either totally or partly in any appropriate fashion. For instance, there may be used for this purpose small boards or slats of wood, metal or other material, straps, woven material, cushions with or without springs, basket-work or leather, these fittings being arranged in such a way as not to hinder the articulation of the jointed members. y

In a modification, two stops and two struts are provided upon the low and rigid seat, which stops and struts are provided at the lower ends of the supports for the back-rest in such a way that the trestle, constituted by the back-rest and its support, and the two struts can form four legs for the seat thus modified.

The following description illustrated by Serial No. 532,812.

the accompanying drawings by way of eX- ample, will enable the invention to be carried into effect.

Figure l shows a perspective view of the seat opened out.

Figure 2 is a plan of the seat folded up and seen from underneath.

Figure 3 represents inperspective another form of the device in the open position;

Figure el is a plan of Figure 3 showing the device folded up.

The trestle, composed of two frames, the one a forming the back-rest and the other b forming the support, pivoting one on the other at c, is itself hinged or jointed at d upon the plan or plate which forms the seat proper. In the example described, this plate is formed of two side pieces e united by cross-members and strips of wood or slats f. The side pieces e are provided with small feet g by which the device may rest firmly upon the ground.

It will be seen that the inclination of the back-rest can be varied by increasing the separation of the legs or surfaces a Z; of the trestle. l

In order to fold up the device, the frame b is closed between the branches of the frame a; this latter is afterwards folded by pivoting on its axes al below the seat proper and between the side pieces e as shown in Figure 2.

By reason of the particular arrangement which forms the subject of the invention, the seat possesses great firmness and strength, the centre of gravity being very low and the back-rest directly bearing on the ground through the legs or struts b; on the other hand the occupant of the seat can stretch himself comfortably thereon, his back being sustained in the selected position, by the back-rest which is inclined to the desired angle.

The shapes and the accessory arrangements of the various parts of the arrangement described, their dimensions, the materials and means of construction, the working of the three principal parts (seat, backrest and support) and the jointing means can be varied without departing from the present invention.

In the modification of Figures 3 and 4, the supports Z), instead of resting on the ground at their free ends, as in the previous construction (Figures 1 and 2) are brought back below the seat (Figure 3) and their ends are cut to form stop-notcl'ies or nicks h to serve as lodgments for one or two pieces forming abutments, provided. at the front of the seat; in the example given, rthe abut ment piece is constituted by the cross-bar j situated at the front of the seat.

Each of the struts i is mounted on pivots at one of its ends, by means ot screws il? 'for example, or by any other means, upon one of the support-sides near .its base, rlhese two struts are reinforced by one or more cross-bars connecting them.

The additional trestle thus constituted by the struts z' and their cross-bars, can pivot upon its axes ol attachment .2, until the bealis Z provided near the pivot-ends of the struts fz', come into abutment against stops provided upon the supports 6,' in the example given these stops are formed by the cross-bar m.

Owing to this device, the seat now 1Dossesses four legs or raised feet connected with it in a rigid manner:

(l) Two are formed by the stiles d, constituting the baclr member in the former invention, these stiles being rendered 'fast to the seat by the action ot the supports Z) gripping by means of the notches /i a part (for example the cross-bar j) situated at the front of the seat;

(Q) The two others are constituted by the two struts t' supporting the members Z), upon which the liront of the seat rests, these struts being slightly inclined backwards, so that the weight upon the seat tends to accentuate their opening, which on the other hand is limited by the bea-ks Z bearing upon the abutments provided upon the supports b, viz the cross-bar m in the example given.

The low and rigid seat shown in Figures l and 2 can thus be transformed rapidly into a seat upon legs or raised feet, substantially at the height of an ordinary folding seat, suliiciently strong even to serve as a stool, while yyet retaining the faculty ot resuming at will its irst character of low seat for repose.

It is understood that modiiications, additions and improvements within the scope ol? the invention, can be made in the arrangement described.

`W hat l claim is l. A, portable folding seat comprising a seat member, having an abutment piece at one extremity in combination with a trestle composed of a pair or struts, the upper ends of which are pivotally connected with the other extremity of the seat member, a pair of supports pivotally connected at one end with the lower end of said struts and engaging at their other ends the abutment piece of the seat member, and a second pair of struts pivoted to the supports near their place of engagement with the abutment piece,

2. A' portable folding seat comprising a seat member, having an abutment piece at one extremity in combination with a trestle composed of a pair of struts, the upper ends of' which are pivotally connected with the other extremity of the seat member, a pair of supports pivotally connected at one end with the lower end oi' said struts and engaging at their other ends the abutment piece ot the seat member, and a second pair of struts pivoted to the supports near their place of engagement with the abutment piece, and cross bars reenforcing the struts and supports.

3. A portable folding seat comprising a seat member in combination with a trestlc pivoted thereto, said trestle being composed ot a pair of parallel struts pivoted at one extremity to one edge of said seat member, a pair of supports pivotally connected at one end with the other extremity oi said struts, and a second pair of struts pivoted at one extremity to the other end oit said supports, means for engaging the last mentioned end oi? said supports with an opposite edge oi said seat member, and means for limiting` in one direction the pivotal movement oi said second pair of struts, said trestle being invertible to form a back-rest with said seat member in lowered position.

4s. A portable folding seat, comprising` a seat member, a trestle pivoted thereto along one edge of said seat member, an abutment piece at the opposite edge of saidy seat meinber, said trestle being invertible to form a back rest with said seat member in lowered position, means tor engaging said trestle with said. abutment piece with said seat member in raised position, and a pair ofstruts pivoted to said trestle near their place of engagement with said abutment piece.

5. A portable folding sea-t, comprising a seat member` an abutment piece along one edge of said seat member, and an invertible trestle pivoted to the opposite edge of said seat member, saidtrestle comprising a pair ot struts pivoted to said seat member, a pair ot supports pivoted at one end to said struts and having at their other end means for engaging said abutment piece, and a second pair ot' struts pivoted to said supports, said supports having their movement limited in one direction and being foldable in the other direction into line with said supports, the partly folded trestle being then invertible to constitute a back rest for said seat member in its lowered position.

ln testimony whereof I have aftixed my signature.
