Abstract
Official abstract text for this publication.
A vehicle seat includes a seatback; a headrest that has a stay; and a headrest support that is arranged on an upper portion of the seatback so as to extend in a vertical direction, and that supports the stay in a manner that allows the stay to move in the vertical direction with an outer surface of the stay in sliding contact with a surface of an inner cylinder portion of the headrest support. The surface of the inner cylinder portion is covered by a resin coating that has a lower coefficient of friction with respect to the outer surface of the stay than material of which the headrest support is made.
First claim
Opening claim text (preview).
1 . A vehicle seat comprising: a seatback; a headrest that has a stay; and a headrest support that is arranged on an upper portion of the seatback so as to extend in a vertical direction, and that supports the stay in a manner that allows the stay to move in the vertical direction with an outer surface of the stay in sliding contact with a surface of an inner cylinder portion of the headrest support, the surface of the inner cylinder portion being covered by a resin coating that has a lower coefficient of friction with respect to the outer surface of the stay than material of which the headrest support is made. 2 . The vehicle seat according to claim 1 , wherein: the headrest support is fixed to the seatback by being fitted into the inner cylinder portion of a vertically extending cylindrical support bracket that is attached to a back frame of the seatback; and a surface of an outer cylinder portion of the headrest support is covered by the resin coating. 3 . The vehicle seat according to claim 1 , wherein: the stay is configured such that movement thereof in the vertical direction is restricted when an engaging portion provided in a manner able to move in and out on an upper end portion of the inner cylinder portion of the headrest support engages with an adjusting groove formed on the stay, and movement thereof in the vertical direction is allowed when the engaging portion disengages from the adjusting groove; and a surface of the upper end portion of the inner cylinder portion of the headrest support is not covered by the resin coating. 4 . The vehicle seat according to claim 2 , wherein: the stay is configured such that movement thereof in the vertical direction is restricted when an engaging portion provided in a manner able to move in and out on an upper end portion of the inner cylinder portion of the headrest support engages with an adjusting groove formed on the stay, and movement thereof in the vertical direction is allowed when the engaging portion disengages from the adjusting groove; and a surface of the upper end portion of the inner cylinder portion of the headrest support is not covered by the resin coating.
