THEATER (31min Roger Andr Chaillot, Paris, France, assignor to Societe Anonyme dite: Societe Marocaine fle Constructions Mecaniques. Application August so, 1945, SerialN'o. titi''e In France December 8', 1944 llaims. (o1. it s-i91 The present invention relates to a chair and more particularly to a chair of the type utilized in public places such as. theaters, auditoriums and the like.

It is an object of the present invention to provide such a chair, preferably of pressed material, so constructed and arranged so as to avoid the many drawbacks attendant to Wood or metal framed chairs conventionally utilized in public places.

It is an additional object to provide a chair frame structure such that With a single frame type more varied styles, colors and artistic eifects of the seating arrangement are obtained while simultaneously providing the utmost in comfort and a structure that complies With all the safety regulations in force as regards fire hazards and sanitation.

Moreover, the chair according to this invention is far stronger than those in use at present and cannot damage the occupants clothes.

The chair according to this invention is of improved construction and comprises a frame consisting of a pair of similar shell halves connected with each other in the plane of symmetry of the chair: said shell halves are assembled preferably by means of lugs bent into said plane of symmetry and received in a supporting and stiifening member conforming to the curvature of the shells and having a U-shaped section, between the flanges of which said lugs are secured, for instance, by means of bolts and nuts.

Where such chairs are used in play-houses or at least are grouped in rows of similar elements interconnected laterally, one single front leg and one single back leg are preferably provided in each supporting element, in the plane of symmetry of the chair, and rigid with respect to the supporting member.

The shell halves forming the frame are designed so that the frames when grouped in rows can be secured easily. For that purpose they are provided, preferably at the front of their outer edges, with bent lugs to be secured by-pairs in any suitable way, to interconnect them rigidly.

Arm-rests are laid on flat or plane portions provided for that purpose on the top of the outer edges of the shell halves; 'said arm-rests can be designed to interconnect two adjacent chairs and thus strengthen the connection already secured as described.

The chair can be fitted with a tiltablesat, particularly if used in a play-house and said seat is 'fulcrumed on a rod the ends of which pivot in recesses provided therefori'n 'the"outer =2 edges of the respective companion shell halves. Said seats are designed so that they can be pressed easily; they are made advantageously of two superimposed parts, which permits of alter= ing their appearance more readily and likewise the utilization of padding.

An attached back is formed in the aXi's'of symmetry thereof with lugs to be inserted between the bent lugs on the shell halves and also between the flanges of the supporting member straddling said lugs and to be secured thereto, for instance, by means of bolts and nuts; additional means can be provided on the side edges of the hacks for interconnecting the abutting edges of two adjacent elements.

Other peculiarities will appear from the following description of an embodiment of this invention, reference being bad to the appended drawing wherein:

Figure 1 is an isometric perspective view 'of the various parts whose assemblage provides the chair.

Figure 1a is an isometr'ic p'erspective view of a shell in one single piece; 7

Figure 2 is a longitudinal sectional view on the axis of symmetry of the chair.

Figure 3 is a front elevational view showing how two adjoining chairs ar assembled, and Figure 4 is an enlarged sectional view taken on line IV -IV in Fig.3. I

Figure 5 is a horizontal sectional view taken opposite part I 6 in Fig; 2.

The chair shown comprises a frame having substantially the shape of 'a-quartersph'ere hav ing upwardly and forwardly extending edges aha consisting of a pair ofsymmetric shell halves 'l, a supporting and stiifening member 2, a back} andfa tiltable seat 4. In F'igure 1a a single shell la constitutes a frame component and will be-described in detail hereinafter.

Each shell half is-formed with' an inner'edge 5 bent at right angles anddrilled with two holes 6 at its upper portion andwith one hole I at its lower portion; its outer'edge is formed with a tongue 8 to be used rer, attaching asimilar juxtaposed element, and withabore "9 to receive one of the trunnions about which theat 4 1 s tiltable.

The supporting and stiifening "member has a U-shaped section, 'thefianges'of which are drilled with a pair of holes l0 at their upper portions and one hole at their lower ends. The supporting and stiffening member is formed or provid'e'd with a back leg 12 entrancinle is; "the legs 12 Y and 13 can "be fitted at tires 'n'ds with bearing members l4 and I5 suited to the particular way in which the chair is anchored, such as by nailing, screwing, sealing.

The back 3 is provided on its rear surface in its axis of symmetry thereof, with a pair of lugs Hi to be inserted between the bent edges 5 of the pair of shell halves I providing the seat frame, which in turn are inserted between the flanges on supporting and stiffening member 2. The lugs l6 are drilled with holes I! while bolts are passed through holes l0, 6 and H for holding the supporting member, the two shell halves and the back in assembled relation.

The seat is provided with a pair of trunnions 18 to be received in recesses 9 provided for that purpose. The seat is also provided at the rear thereof and in its plane of symmetry with a fiat finger [9 to be engaged in the guide provided therefor by the groove or space existing between the bent edges 5 of the companion shell halves which in turn are straddled by the flanges on the supporting member. Yielding abutments 20 stop said finger in its end positions. A spring 21 wound about the trunnions l8 urges the seat permanently towards its lifted position by a rocking motion about the axis of its trunnions l8.

Said seat is made of two parts, namely, a frame 22 carrying the trunnions l8 and formed with ribs 23 and a member, 24 providing a cover and having its edges 25 fitted over the edges of the frame22, the ribs 26 being in alignment with the frame ribs .23.

Removable arm-rests 21 are secured by any suitable means on top of the sides of the shell halves. r 7

For the purpose of uniting two adjoining chairs ina row the connecting arrangement illustrated in Figs. 3 and 4 may be used:' the lugs 8 provided at either outer edge of the shell halves l are clamped between fish-plates 38, 3| by means of bolts 32 whose heads 33 are flush with fishplate the said fish-plates are suitably shaped in cross section to firmly hold the lugs 8, while the front face of fish-plate 38 is so designed that a pleasant appearance of the whole is secured.

It will be appreciated that this particular provision of only two legs for each chair, arranged in the plane of symmetry of the latter, enables the chairs pertaining to the same row to be arranged easily in any desired curve, particu- J ment the frontand rear faces of this shell mem her are provided respectively with a groove and an outwardly extending lug or rib located in the plane of symmetry thereof. The groove in the front face accommodating the finger IQ of the seat 4 and the protuberance or rib on the rear face cooperating with the flanges on the supporting and stiffening member 2.

It is to be remarked, however, that the utiliza tion of two shell halves permits the use of much smaller dies thereby rendering the pressing operation more economical and simpler. It is obvious that the supporting and stiffening member could be provided with a different cross section iii 4 other than the U-shaped section illustrated although as readily appreciated such a section is particularly advantageous in view of the many purposes for which this member 2 must serve.
