Theatre chair

Abstract

A theatre chair having a frame to which there is connected at least a seat component ( 21 ) and a backrest component and, providing means on the seat component ( 21 ) to co-operate with a seat member ( 30 ) and means on the backrest component to co-operate with a backrest member whereby the seat member ( 21 ) and backrest member can each be readily attached to the appropriate component to be positively affixed thereto, the members being able to be removed from the appropriate component when required. The connection between the components and the members can be by way of interacting lugs ( 24 ), interacting ribs ( 26 ) and means ( 25 ) whereby the parts are held in compression and tension. Means to rapidly replace the upholstery and means whereby the same components can be used for chairs of different widths are also disclosed.

1 . A theatre chair having on the underside of the seat component, on each side thereof, a recess adapted to receive a pivot shaft assembly which has means whereby it can be connected to the seat component characterized in that the pivot shaft assembly can be located at different positions relative to the side of the seat so that the pivot shafts can co-operate with chair frames having different spacings, and thus the seat component can be used in seats having different widths. 
   
   
       2 . A theatre chair as claimed in  claim 1  wherein the pivot shaft assembly includes a pivot shaft and a plate to which the shaft is attached, the plate having means whereby it can be attached to the seat component. 
   
   
       3 . A theatre chair as claimed in  claim 2  wherein the plate of the pivot shaft assembly has an aperture therethrough and a stud passing through the seat component through the aperture to a nut whereby the pivot shaft assembly is connected to the chair component. 
   
   
       4 . A theatre chair as claimed in  claim 3  wherein the seat component has a plate through which the force holding the pivot shaft assembly is passed to the chair component, the plate having an elongated aperture so that the connection can be made with different lengths of the pivot shaft extending therefrom.
