Abstract

The specification describes the construction of a seat and a backrest for a tip-up type theater chair. A resilient body is covered on one face and four edges by a removable fabric cover. The cover has a hem containing a reinforcing cord. There are a number of eyelets formed in the fabric cover adjacent the hem. The resilient body is supported on a rectangular frame which has a number of hooks projecting into the rectangular space inside the frame and towards the resilient body. The hem of the cover is taken around the frame, underneath it and into the rectangular space within the frame where the apertures along the hem are hooked onto the hooks on the frame. The cover is thus held tightly over the resilient body. The frame is held in a casing and the casing together with the frame and upholstery forms a unit (backrest, armrest or seat) for a chair. The construction of the casing is discussed in detail.
