8, Claims. (01. 155-116) present invention relates to chairs and V inure particularly to chairs of the retracting type for installationin theaters, auditoriums and the The primary objects of the invention are to provide an improved chair of the retracting type whereinthe chair occupant may move rearwardly in a sitting position in order to permit other theaterpatrons to pass in front of him; to provide such a chair which is of simple construction 21 and which comprises few moving parts; to proride such a chair which maybe easily and com-,

i ortably retracted and returned to forward position by the chair occupant; and in general to provide a retracting chair which is eflicient in operation, reasonably economical in manufacture, and attractive in appearance.

An illustrative embodiment of the invention is shown in the accompanying drawings, wherein: Figure 1 is a perspective view of a retracting chair in its forward position of occupancy;

Figure 2 is a sectional view of the same taken on line 2-2 of Figure 3; i i Figure 3 is a fragmentary front elevational View showing the right hand side of the chair;

Figured is a perspective view similar to Figure 1 and showing the chair in its rearwardly retracted position; and

Figure 5 is a sectional view similar to Figure 2 and showing the parts of the chair in their rearable manner and which may if desired be rigidly connected by a suitable cross-tie (not shown).

As here shown, the only connections between the atandardsare the chair parts hereinafter described and the floor upon which the standards are installed, and the word frame as herein Bed is intended to include spaced standards as well as a unitary structure. 1 The chair proper generally comprises a seat and back assembly in which the chair seat I l and the chair back l2 are pivotally connected for relative movement. The chair back I2 is mounted at its opposite sides on spaced back carriers I3 as by means of rivets i4, The chair seat II is mounted on spaced seat carriers l5 at opposite aides thereof bymeans of brackets l6 secured to the seat Ii byrivets l1 and which brackets ISare pivotally connected at IE to the seat carriers l5. The rearward ends of the seat carriers l5 are plvotally connected at l9 to the lower, rearward parts of the back carriers l3.

ends or corners of the adjacent back carriers l3 thus connecting the seat and back in pivoted assembly.

The seat carriers l5 and back carriers I 3 are mounted on the standards ill by meanssof rear depending links 20 having their upper ends pivotally connected to the standards and their lower ends pivotallyconnected to the seat carriers and back carriers at their pivotal connection IS. The seat and back assembly is thus supported in the rear for forward and rearward movements by the swingable depending links 20.

Intermediate depending links 2| support the back carriers I3 and back I 2 forwardly of the rear links 20, said links 2| having their upper ends pivotally connected to the standards I0 and their lower ends pivotally connected to the forward These swingable intermediate links 2| are of greater length than the rear links 20, and by this arrangement as the chair back is moved rearwardly it is also tilted to a near-vertical position thus to minimize the space required to the rear of the chair for retracion.

The forward portions of the seat carriers l5 and of the seat I I are forwardly-rearwardly movably supported by swingable, upstanding front supporting levers 22 having their lower ends pivotally connected to the standards I!) and their upper ends pivotally connected to the upper forward corners of the seat carriers I5. These front levers 22 are preferably connected by a cross-tie or strut 23 which adds to the stability of the structure.

It will be seen that as the chair is retracted by the occupant thereof, the seat moves rearwardly in asubstantially straight path while the back moves rearwardly and is simultaneously turned to a near vertical position as seen in Figure 5. This rearward retracting movement is stopped by contact of the front levers 22 with stops or bumpers 24 on the standards i l. Forward, returning movement of the chair from its position shown in Figure 5 to its position shown in Figure l is similarly stopped by contact of the front levers 22 with stops 25 on the standards.

It will be seen that the chair seat I] 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 IS. The seat is supported in its lowered, substantially horizontal position for occupancy by cooperating stops 26 on the brackets l6 and 21 on the seat carriers I5.

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