Abstract
Abstract A removable headrest for chairs includes a pocket which is formed to fit over the upper portion of the back of a chair, such as a folding lawn chair or the like. The headrest may be adapted to other types of chairs as well. The pocket portion is preferably formed of a resilient plastic material and includes a relatively thick back panel for structural strength, and a relatively thin front panel in order to conform comfortably to the upper back of a person seated in the chair. The pocket portion may have a single headrest support arm channel formed in the central back portion, or may alternatively include opposite support arm channels formed along each edge of the pocket. Greater versatility may be provided by including a central channel and both side channels in the same seat back pocket portion. The channels may be continuous or may be formed in several segments. The channels provide for the adjustable insertion of either a single central headrest support arm therein, or a pair of opposite support arms, according to the configuration of the pocket portion which fits over the back of the chair. A threaded bolt type support arm lock, or an over center cam lock may be used to fix the position of the support arm(s) as desired. A single headrest is affixed to the upper end of the single support arm, or alternatively a headrest band is extended between the two lateral support arms, according to the headrest configuration.
