  • Patent number: 5108150
    Abstract: The present invention relates to an improved head rest and neck support assembly for seating furniture. The assembly contains an elongated support bar which is mounted horizontally to the seating furniture behind the neck of a prospective user. One end of the support bar has a pivoting carrying element with a cushion attached thereto. The cushion may swivel between a neck support position and a side head rest position. In a second embodiment, the elongated support bar in the assembly has a groove running the length of the bar. The cushion is also elongated and possesses a track or partial track which cooperates with the groove in the elongated support bar to allow the elongated cushion to slide horizontally along the bar. A portion of the track is capable of exiting the groove and allowing the elongated cushion to bend into an L-shape.
