I 6 Claims. 1

The present invention relates to chairs and mm! wtiwularly to chairs of the retracting type 1w humiliation-in theaters, auditoriums and the m 'Ihioappiieation is a continuation-in-part 1am co-oendins application Serial No. 686,674, Wil -1132?; 1946.

obiects of the invention are to wovide-mimpmved chair of the retracting type mm the vhair occupant may move rearwardly in a sitting position inorder to permit other the I occupant; and ingeneral to provide a re"- whieh is efficient: in operation, reambty economical-in manufacture, and attractive-inappearame.-

In and secured mtomconventionaimanner.

The chair proper generally comprises a seat and back assembly in which the chair seat Iii-and the chair back M are pivotall-y connected for rel-a tive movement. The chair back M- is mounted at its opposite sides on spaced'ba'ck carriers l5 as by means of screws or rivets It. The chair seat I3 is mounted on spacedseat' carriers l1 atopposite sides thereof by means of brackets I8 secured to the seat i3 as by rivets lfl and which brackets it are pivotally connected at 20 to the seat car riers H.

The rearward ends 01' the seat carriers H are pivotally connected at H to thelower; rearward ends or corners of the adjacent back carriers it; thus connecting the seat and back in pivoted assembly.

The seat carriers l1 and back carriers II are mounted on the standards in: byfimeans' or rear depending links 22 having their upper ends pivotally connected to the standards and their lower ends pivotally connected to depending rear legs 23 of the seat carriers IT. The seat and back assembly is thussupported in the rear for -forward and rearward movements by the swingable depending links 22 Intermediate de ending links 24- sunuort-the back carriers l5 and back l4 forwardly of the rear links 22, said links 24 having: their upper ends pivotally connected to the standards it and their lower ends pivotally connected to the for"- ward parts of the backcarriers I5 These swing-'- able intermediate links are or greater length than the distance between the pivotal connections of the links 22 to the standards I0 and thepi'votal connections between the seat carriers I1 and the back car'riers'l5, and by this arrangement as the chairb'ack is moved rearwardl y it is also tiltedto' a near-vertical position thus to minimizethe space required to the rear of the chairi'o'r retraction.-

The forward portions o'fthe seat carriers I1 and oi" the seat It are forwardly-rearwardly movably supported by swingable, depend'ing iront links-128' having their upper ends pivotally connected to the standards It) and their lower ends pivotallv connected to depending. front legs 28 on the seat carriers H.

It will be seen that as the chairis retractedby the occupant thereof, the-seat moves rearwardiy in a substantially straight path while the back moves rearwardly and issimultaneously tiirned to a near vertical position: as: seen in Figure 5'.- Ihis rearwardvretracting movementis stopped by contact of the front links 25' with the: cross tie l t of the frame. Forward, returningmoveinent: oi the chair from itsposition showni-n Figure ate its position shown in Figure 2 is similarly stopped by contact of the depending rear legs 23 of the seat carriers [1 with the cross-tie l I.

It will be seen that the chair seat l3 may be folded upwardly to facilitate sweeping under the chair independently of its retracting and returning movements, by reason of its pivotal mountings on the seat carriers IT, and the seat is supported in its lowered, substantially horizontal position for occupancy by cooperating stops 2'! on the brackets l8 and 28 on the seat carriers l1.

Figures 6-8 inclusive and Figures 9-10 illustrate two modified constructions designed to reduce the amount of work required to install chairs of this type in a theater and thus to reduce installation costs. In Figures 6-8, the upper ends of the links 22 24 and 25 are pivotally connected to a mounting member which fits into a recess 3| in the adjacent standard I0 The mounting members 30 of adjoining chairs which members are thus fitted into recesses 3| on opposite sides of a middle standard I0 are secured in place by means of a single bolt 32 passing through aligned apertures in the mounting members and the standard, and provided with a nut 33.

In Figures 9 and 10, the upper ends of the depending links 22 24 and 25 are similarly pivot ally connected to a mounting member 35 which fits into a recess 36 in the adjacent standard lil The mounting members 35 of adjoining chairs which members are thus fitted into recesses 35 on opposite sides of a middle standard [0 are secured in place by means of a flanged plate 31 fastened as by screws 38 to the underside of the armrest H Inwardly turned flanges 39 on the plate 31 are slid into grooves 40 in the standards and ll in the mounting blocks to thus secure these parts in assembly.

In either of the modifications above described, the depending links of the structure may be assembled to the

mounting members

30 or 35 at the factory where costs are usually lower than at the place of installation. The chair units thus assembled may thereafter be readily installed on standards previously set in place in a theater or the like.

While but several specific embodiments of the invention have been herein shown and described, it will be understood that numerous details may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.
