(Cl. y155-115) 110 Claims.

The present invention relates to chairs and more particularly to those of the so-called opera type.

The primary objects of the instant invention are to provide a chair of the general character above indicated having a seat which is rearwardly movable on a substantially horizontal plane for a limited' distance;l to provide such a chair whose seat is upwardly tiltable as well' as rearwardly horizontally movable; to provide such a chair whose back is so connected with the seat that a rearward' movement of the seat effects a slight forward movement of the upper end of the back and a slight rearward movement of the bottom end thereof; to provide such a chair which when installed as one in a plurality of rows of like chairs and which when occupied provides for ready and convenient egress from and ingress to unoccupied seats in the same row without seriously disturbing the occupant of such an occupied chair or the occupant of a chair immediately rearwardly of such occupied chair; and, to provide such a chair which is comfortable and convenient in use, relatively simple in mechanical construction and reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawings, wherein:

Figure l is a side. elevational View of the chair with its seat and back in their respective positions of normal occupancy of. the chair;

Figure 2 is a fragmentary front elevational view thereof;

Figure 3 is a side elevational View of the chai-r similar to that of Figure 1 but showing its seat and back when moved by the occupant thereof to their respective positions in instances wherein aperson seeks ingress to or egress from another chair in, the sam-e row of chairs and past such occupied chair;

Figure.` 4 is an enlarged, fragmentary side elevationalview of the chair, partly in section, and showing its. seat and back in their respective positions of normal occupancy of the chair; y

Figure is a sectional `view thereof on line 5--5 of Figure 4;

Figure 6, is an enlarged, fragmentary side elevational view ofthe chair, partly in section, and similar to that of Figure 4 but showing its seat and back when` moved by the occupant thereof to their respective positions in instances wherein a person seeks ingress to orl egress from another chair in the same row of chairs'and past such occi-ipiedchair;` t

I on the equalizing strut or rod`2 I. A

Figure 7 is a sectional View thereof on line 'I-1 Figure 10 is a sectional view on line Ill-I0 of Figure 4; and

Figure 11 is a sectional view on line II-II of Figure 4.

Referring then to the drawings wherein like parts of the structure shown are designated by the same numerals in the several views, the chair there illustrated comprises a pair of spaced vertically disposed standards I0, each provided with an arm rest II secured to its upper end in any suitable fashion and in any convenient manner.

Each standard I0 is provided adjacent its lower forward end with a sleeve I2 projecting laterally from its inner surface and an upwardly extending arm I3 is pivotally secured at its lower end by means of a pivot pin I4 embraced within each sleeve I2.

The upper end of each arm I3 is pivotally secured to the forward end of a generally triangularly formed bracket I5 between which pair of brackets the upholstered chair back I6 is secured and a strut I'I, here shown as tubular in form, is interposedbetween the arms I3 to form an equalizer and which strut likewise provides for structural rigidity.

A pair of generally horizontally disposed links I8, each pivotally connected adjacent its rear end to a back' supporting bracket I5 rearwardly of the pivotal connection of an upwardly extending arm I3 with its bracket I5, are each pivotally connected adjacent its forward end to a link I9 whose other end is pivotally connected to its adjacent arm I3 below the pivotal connection of said arm with the back supporting bracket I5.

A pair of upwardly extending links 29, each pivotally connected at its lower end to the inner surface of a standard I, are each pivotally connected at its upper end adjacent the upper end of' a back supporting bracket I5. An equalizing strut 2| interposed between the pair of links I8 intermediate the ends of each link and here shown as tubular in form supports an upholstered seat 22 pivotally mounted thereon for upwardly tilting movement betweenv each vertically disv posed standard I0. The seat 22 is provided. with a bracket IDU adapted to engage thewlink i8" to check the forward pivotal movement of the seat A stop 23 is mounted on the inner surface of each standard Ill whose rearward end 24 engages a link 20 when the seat 22 is in its normal forward position of occupancy as shown in Figure 4 whereas the forward end 25 of each stop engages an arm I3 in instances wherein the seat 22 is moved rearwardly by the occupant thereof as shown in Figure 6. Y

Since each"link I8 is disposed substantially horizontally in its pivotally connected relation to the seat 22 and since each link 2l) is slightly swingable forwardly-rearwardly about its lower pivotal connection, all as best shown inliigures 4 and 6, the seat 22 and back IB are eachvforwardly-rearwardly movable to provide ready and convenient egress from and ingress to unoccupied seats in the same row without seriously disturbing the occupant of such a chair or the occupant of a chair immediately rearwardly of such occupied chair. i. f v f It will thus be seen that the chairklheyrein shown and described is comfortable in use,is relatively simple in mechanical construction and is reasonably economicalin manufacture, and While but one specific embodiment of the invention has been herein shown and described, it will be-understood that certain details of the construction' shown may be alteredor'omitted without departing from the spirit of the invention as the same I is defined by thefollowing claims.v
