vClainis. (Cl. 155 --180) The present invention relates to chair seats; and its objectis to provide an improved chair seat comprising alower or base member and an upper member carryingthe upholstery of the seat, said members being detachably connected so that they may be readily separated for re pairing'or' replacing the same or the upholstery or other parts thereof; and. further, to provide improved means for detachably connecting said members, and improved means for mounting and holding the upholstery securely in place.

This and any other and more. specific objects hereinafter, appearing are attained by, and the inventionfinds preferable embodiment in, the illustrativestructure particularly described in the body of this specification and illustrated by the accompanying drawings, in which: a

Figure 1 is a top plan view of the seat of a theatre chair or the like, the upholstery thereof being partially broken away to show parts undemeath;

Figure 2 is a vertical sectional view thereof taken on line 2-2 of Figure 1;

Figure 3 is a vertical sectional view of forward parts of the same; taken on line 3--3 of the chair, the seats base or lower member and the seats upholstery-carrying upper member being shown separated; a

Figure 8 is an elevational interior fragmentary view, of portions of the chair seat;

Figure 9 is a vertical sectional view thereof taken on line 9-9 of Figure 8.

In order to readily apply, remove or replace the upholstery of the seat of a theatre chair or the like, it is desirable to separate the part of the seat which carries the upholstery from other parts of the seat. To effect such ready separation, the illustrated seat comprises a concave lower member or pan I and an upper member 2 separable therefrom and carrying the upholstery 3. The pan I, of sheet metal or the like, has an upwardly extending rim 4 with an inwardly extending flange or edge portion 5 curved inwardly-downwardly as shown.

The upper member 2 of the seat includes a rigid frame 6' extending circuitously parallelly with the rim 4 and" supported thereby, i. e. on the inwardly-downwardly curved edge" portion'i thereof. This frame-5 has an inwardly extend: ing flange l with a downward extension 8,

The upholstery, comprising the flexible sheets 9, III and stufling ll therebetween is carried by the uppermemberl and is mounted adjacent the peripheral edges of the sheets on'the downward extension 8 of the franies inwardly extending flange l, and may be folded at I: around said extensions lower edge I3 and held in place thereon by clips l4 clamping'the sheets onsaid extension as shown., in-Figures 8 and 9; orand preferably the upholstery is held in place by the spaced spurs I5 extending downwardly from said extensions edge and thrust through the peripheral edge portions of the sheets as shown in other views and particularly well shown in Figures5and6. I

Additionally to said clips or spurs or other means for mounting the upholstery on the 'upper member's frame 6, the upholstery in the assembled and connected position of members I and 2 is held in place by being clamped between said members, i. e. between the inwardly extending flange l of the frame and the inwardlydownwardly curved portion 5 of the rim 4 of the lower member I. It will be seen that this clamping of the upholstery is augmented by the weight of the occupant of the seat. 7

' The seats said members i, 2 are releasably held in connected or assembled position bysuitable means, as the spaced outwardly extending, and outwardly-upwardly curved, arms iii of the downward extension 8 of the frames inwardly extending flange 1, these arms engaging and hooking under the lower edge I] of the inwardlydownwardly curved upper edge portion 5 of the lower member's rim 4. Opposite these arms IS the upper and lower members I, 2 are releasably held connected by suitable means as the screw I8 extending at l9 through the rim 4 and threaded at 20 in the frame 6 as shown in Figures 4 and 7.

To yieldingly support or cushion the upholstery, springs mounted on the frame are provided, such springs 2| as shown being undulate and upwardly bowed. The end portions 22 of these springs are inserted between the body 23 of the frame 6 and a clip portion 24 slit and pressed therefrom as best seen in Figure 5.

Downwardly bowed bars 25, mounted at their oppositeends 26 on the frame 6 and extending between the opposite sides of the seat and resting on the lower member or pan l medially thereof, serve to additionally support the frame adjacent the ends of the springs 2!. These bars being mounted on the frame I are removable with the upper member 2 from thelower member i.

' The seat may be mounted on a suitable supporting standard 21 in any desired way. --In Figure 7 the lower member I is turnable on the horilontal spindle 28 whose vertical arm 29 is seated in a socket 3| in the standards cross bar It will be seen. that the upper member 2 of this -seat may be readily disconnected and removed from the lower member I; that these members being separated. the upholstery may be readily removed from the upper member for cleaning, repairing or replacement; that the upholstery is securely mounted on the upper member 2; that the upholstery is clamped adjacent its edges between said members i and 2; and that the frame I is additionally supported adjacent the ends of the springs 2i by bars 25 which are mounted on the upper member and removable therewith.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of any particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim: I
