(under subclass 391) Device comprising a headrest complete in itself, movable from association with one seat to association with another seat, and including means by which the headrest may be secured to or mounted on a seating device and readily removed therefrom without employing fixtures mounted on the seat.
(1) Note. The subclasses below this and the indented subclasses (i.e., subclass 403 et seq.) contain many patents in which the headrest is removably attached to a seat by fixture such as a seat mounted socket or the like. When the fixture is attached to the seat, or the seat is modified to receive the headrest, the patents have not been considered "portable" for subclasses 397+, but have been classified on the features indicated in subclass 403 et seq.
