Abstract
Abstract A headrest apparatus for securing to a seat having a back rest, the back rest having an upper end and a front face and a rear face includes a flexible sheet member for wrapping over the upper end and having a sheet member first end for extending down the rear face of the back rest and a sheet member second end for extending down the front face of the back rest, a pair of lateral head support cushion members secured to the sheet member second end and laterally spaced apart from each other a sufficient distance to receive between them the head of a user for comfortably retaining the head against lateral sliding and rotation, and a mechanism for securing the apparatus to the back rest. The cushion members preferably include inflatable sacks having inflation and deflation mechanisms. The inflation and deflation mechanisms preferably include a tube having a tube opening and a removable tube cap for receiving air delivered by a user exhaling to inflate the sack, and for releasing air for deflating the sack, and a check valve for additionally safeguarding against unwanted air escape through the tube. The mechanism for securing the apparatus to the back rest preferably secures the apparatus removably. The mechanism for securing preferably includes belts for wrapping around a portion of the back rest, a buckle for removably securing the belts tightly around the portion of the back rest.
