ABSTRACT:
An automotive seat assembly is provided including a seatback assembly including an upper seatback surface and a guide stem positioned within. A head restraint post is positioned within the guide stem, and includes a head restraint mount end and a seatback insertion end. A head restraint element is mounted to the head restraint mount end. A roller guide is mounted in proximity to the upper seatback surface and comprises a bezel element inserted into the guide stem. A primary roller housing is mounted to said bezel element and forms a center cylindrical path through which the head restraint post passes. A primary roller element is rotatably mounted within the primary roller housing and is biased into communication with the head restraint post by way of a roller bias such that the head restraint post is restrained from motion absent the application of a vertical adjustment force. A housing cap is mounted over the bezel element.
