4 Claims.

The present invention relates to chair seats and more particularly to seats for chairs of the opera type.

The primary objects of the instant invention are to provide a seat for a chair of the character above indicated whose forward portion or front edge thereof is somewhat more resilient than its upper portion; to provide such a seat whose front edge is sufiiciently resilient to make for the comfort of its occupant adjacent the under sides of his knees; to provide such a chair whose seat gives its occupant a sense of luxury; and, to provide such a chair whose seat is attractive in appearance and economical in manufacture and assembly.

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

Figure 1 is a fragmentary perspective view of a chair of the opera type having a seat of the character above indicated;

Figure 2 is an enlarged top plan view of the seat spring unit and its supporting pan;

Figure 3 is a sectional view of the seat spring unit and its supporting pan on line 33 of Figure 2 and showing the upholstered seat covering;

Figure 4 is an enlarged sectional view on line 44 of Figure 2 showing the manner in which one end of a springmember is secured and likewise the manner in which the upholstered covering is secured;

Figure 5 is an enlarged sectional view on line 55 of Figure 2 showing the manner in which the other end of a spring member is secured and also the manner in which the upholstered seat covering is secured; and

Figure 6 is an enlarged perspective view of a single spring member of the characterused in supporting the upholstered seat covering.

Referring then to the drawings in which like parts of the structure shown are designated by the same numerals in the several views, a chair of the opera type is provided with a pair of spaced vertically disposed end standards it] (one not shown) between which is secured the oppositely disposed forwardly extending wing portions l l of the stamped sheet metal back l2 to whose forward side is secured an upholstered covering l3 disposed over padding M.

The seat for the chair includes a pan E5 of stamped and drawn sheet metal whose opposite outer sides are each provided with an outwardly extending rotatable member I6, each fixedly seated within a socket, not shown, which is secured to each inner side of an end standard I!) for tiltably supporting the pan I5 between the spaced end standards In.

A U-shapjed bracket I! is secured at its opposite ends below the rim of the pan [5 adjacent each of its opposite inner sides and afiat bar l8 having downwardly flanged ends I9, each seated within a bracket as best shown in Figure 5, is supported between the inner sides of the pan near the front side thereof.

The rim of the pan I5 is provided with a peripheral groove 20 along its outer surface and the rear length of this groove is provided with a plurality of spaced hooks 2| struck rearwardly therefrom, all as best shown in Figure 4.

Seat supporting spring members each have a forward depending helical and preferably conical portion 22 and an upwardly bowed undulated portion 23 extending substantially horizontally rearwardly therefrom as best shown in Figure 6. The lower end of the conical portion of each spring member is secured to the upper surface of the pan supported fiat bar I8, each in spaced relation to the other and in any suitable manner such as is shown in Figure 5 and the rearward end of each spring member is retained within one of the spaced hooks 2|, all as best shown in Figure 2.

A rod 24 generally conforming in size and shape to the rim of the pan I5 is here shown as sewed within a generally rectangular piece of fabric 25 along the periphery thereof which fabric is disposed over the several spaced spring members in the manner best shown in Figures 3, 4 and 5. Padding 26 such as hair is disposed over the surface of the fabric 25 and an upholstered seat covering 27, likewise generally rectangular in shape and disposed over the padding 26, is provided with a cord sewed therein along its periphery which corded portion is disposed within the peripheral groove 20 of the pan I5.

It will thus be seen that the seat herein shown and described has a forward portion or front edge somewhat more resilient than the upper portion providing for comfort of the occupant of the seat adjacent the undersides of his knees and giving to him a sense of luxury.

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 altered or omitted without departing from the spirit of this invention as the same is defined by the following claims.

I claim:

1. A seat comprising a metal, seat spring unit supporting pan, said pan having a supporting bar secured interjacent the opposite side walls thereof and disposed adjacent its forward wall; spaced tongues struck from the rear wall of the pan and forwardly thereof to form hooks; and a plurality of spaced parallelly disposed spring members, each having a forward depending coiled portion supported on and secured to the bar and. each having an integral rearwardly extending, upwardly bowed undulated portion secured to and supported by one of said hooks.

2. A seat comprising a metal, seat spring unit supporting pan, said pan having a supporting bar secured interjacent the opposite side walls thereof and disposed adjacent its forward wall; spaced tongues struck from the rear wall of the pan and forwardly thereof to form hooks; a plurality of spaced parallelly disposed spring members, each having a forward depending coiled portion supported on and secured to the bar and each having an integral rearwardly extending, upwardly bowed undulated portion secured to and supported by one of said hooks; and a covering for said spring members whose border is secured adjacent the rim of the pan.

3. A seat comprising a metal, seat spring unit supporting pan, said pan having a supporting bar secured interjacent the opposite side walls thereof and disposed adjacent its forward wall, a

groove within the outer walls of the pan adjacent its periphery, and spaced tongues struck from the rear wall thereof and forwardly therefrom to form hooks; a plurality of spaced parallelly disposed spring members, each having a forward depending coiled portion supported on and secured to the bar andeach having an integral rearwardly extending, upwardly bowed undulated portion secured to and supported by one of said hooks; and a covering for said spring members whose border is retained within the groove.

4. A seat comprising a metal, seat spring unit supporting pan, said pan having a supporting bar secured interjacent the opposite side walls thereof and disposed adjacent its forward wall, a groove within the outer walls of the pan adjacent its periphery, and spaced tongues struck from the rear wall thereof and forwardly therefrom to form hooks; a plurality of spaced parallelly disposed spring members, each having a forward depending coiled portion supported on and secured to the bar and each having an integral rearwardly extending, upwardly bowed undulated portion. secured to and supported by one of said hooks; and a covering for said spring members whose marginal edge is provided with a corded border seated and retained within said groove.
