Abstract
A chair back arrangement is provided for use on stackable chairs utilized in convention centers, assembly halls, banquet halls and the like. The chair back includes a large ventilation space centrally located in a upper back portion of the chair. Preferably, the ventilation space is provided by utilizing two, independently mounted, laterally spaced back panels to form the chair back. In the preferred embodiment, each chair back panel is generally trapezoidally shaped and is supported on three sides by an appropriately bent tubular member. The chair back comprises two such tubular members which are integral with rear legs of the chair. It is shown that appropriate tubular material can be selected to provide a preferred flexing of the chair back panels.
