2,492,109` RETRACTING TYPE THEATER CHAIR Joseph G. Prosser and Thomas W. Prosser, Pasadena, Calif., assignors to American Seating Company, Grand Rapids, Mich., a corporation of New Jersey Applieatiun Junezs, 194s, serial No. 679,357

s claims. (ci. 155-116) The present invention relates to chairs and `"niore particularly to chairs of the retracting type for use in theaters, auditoriums and the like. This `application is a continuation-in-part of our "eo-pending application Serial No. 679,354, filed "June 26, 1946.

The primary objects of the invention are to pro- "vide an improved chair` of the retracting type ywherein the occupant may move the seat rearwardlyin order to permit others to pass in front fof him without his having to rise from the seat; *to "provide such a chair having a combination Ililik and roller or link and sliding block mech- 'anismfor mounting the chair back and seat,

l'which mechanism insures easy and comfortable "liorwardand rearward movements and which is concealed below the level of the chair seat; to Fprovide such a chair which when retracted occupies aminimum of space in the rear of the chair; to provide such a chair having improved *means for mounting on spaced chair-supporting standards; and in general to provide such a re- `"tracting chair which is efficient in operation, reasonably "economical in manufacture and attracltiye in appearance. Y

` Illustrative embodiments of the invention are "shown in the accompanying drawings, wherein: -l Figure 1 is a perspective view of a retracting jchair showing the chair seat and back in their "normal, forward `positions for occupancy;

"Figure 2 is a perspective View similar to Figure "lishowingthe chair seat and back in their retracted positions;

Figure 3 is an inside elevational view of the mounting and operating mechanism at the leftharid side of the chair, certain parts thereof beling shown in vertical section taken on line 3-3 r`oflig`ure 4, and the parts of the operating mechanism being shown in .their forward positions;

` Figure 4 is a fragmentary front elevational View of the left-hand side of the chair;

` Figure 5 is a fragmentary inside elevational `view showing the parts of the operating mechalnism in their rearward or retracted positions; l Figure 6 is an enlarged fragmentary sectional lview taken on line 6-6 of Figure 5;

Figure 7 is a sectional view similar to Figure 6 11 and showing a modied construction;

1 Figure 8 is a view similar to Figure 3 and show- "ing another modied form of the invention, the parts of the operating mechanism being shown in `their forward positions;

Figure 9 is a view of the same with the parts loffthe operating mechanism being shown in their ll'felwmdor retracted positions; and

Figure 10 is an enlarged sectional view thereof taken on line III- I0 of Figure 8.

Referring now in detail to these drawings and referring rst particularly toFigures 1 through 6, the retracting chair there shown is mounted on a frame comprising spaced, upright, chairsupporting standards I having inwardly projecting lugs 2 thereon provided with vertical studreceiving slots 3, mounting members 4 having outwardly turned anges 5 with depending, threaded studs 6 adapted to tit into the slots 3, nuts 1 threaded on the lower ends of the studs 6; and a transverse bar 8 secured as by welding to the opposite mounting members 4. The frame thus formed is of sturdy and rigid construction. If desired, members 9 of rubber, cork or other resilient material may be interposed between the anges 5 of the mounting members and the lugs 2 on the standards for absorbing any vibration of the chair during its retracting and returning movements.

The mounting and operating mechanisms on opposite sides of the chair being of like construction, only o ne side is shown in Figures 3, 4 and 5 and hereinafter described. The mounting member 4 has a forwardly and upwardly extending arm I0 on the upper end of which is mounted a guide block or roller II thus forming guides at opposite sides of the frame. A combination seat and back support or carrier I2 is provided with a forwardly-rearwardly extending race or way I3 therein which engages in a groove III in the guide roller Il (see Figure 6) and the carrier I2 is thus mounted on the chair frame for forward and rearward sliding movements.

A rear supporting member or link I5 has its lower end pivotally connected to the mounting member 4. A side plate I6 of generally triangular shape is pivotally connected to the upper end of the rear supporting link I5 and to the rearward end of the carrier I2. This side plate I6 has a forwardly and upwardly extending portion having an inclined race or way I'I therein, which engages in a groove I8 in the guide roller II (see Figure 6) and the side plate I6 is thus mounted for forward and rearward movement with the carrier I2 and rear supporting link I5, and for turning movement about a horizontal axis to thus vary its angular inclination. This turning movement of the side plate I6 takes place about the pivotal connection of the side plate to the rear supporting link I5, and is effected during the retracting and returning movements of the chair by the action of the guide roller II on the inclined way I1 of the side plate. l Y

amados is also turnable about a horizontal axis so that y it may be raised in order touiackilitate Isvtv eeping under the chair. When in its vlowered'position of occupancy, the seat is supportedfrwardly qi its axis of turning moveinei otfs'tops 26 on the carriers l2, onrlfzliichl stops ,thdeal arms 23 rest.

An equalizing strut 21 is desirablyecnred as by welding to the rear supporting links l5 on opposite sides of the chair so that these `links are rigidly secured in assembly and move in uni- Vson, thus addingto `the, stability .ofldthe structure. ""Wl'en they chair is rtravcted,tney "seatfmves rearwardlyin a .substantially straight ..path,y while ,the. back moi/,es reaiwagdlyand also assumes a, near-,vertical position thus .,tominiimizethe space required for rie/tr'action in" .the rearof theu chair. `Ferward ,andrearward-movementsof `the chair are,'stopped lbystop,means. comprising .the ends of the 'ways .I3 V andv l'lyvgl'iich .Contact theguides .orrollerslL Figures 1,-6 inclusive the guides Il are .shown in V,the form offrellersvbut it `will be understood'.,that stationary blecks-lmay ,be employed .in place of rollers.'
