Abstract
A supporting device (8) of a vehicle seat head rest (4) includes a retainer (6, 40) provided with a spring (10, 21, 44) which surrounds a supporting rod (5) of the head rest and resiliently engages therewith to support the head rest (4) at a desired height which can be adjusted in a stepless manner. The frictional retaining force of the spring can be released by an operating member (11, 20, 40) when the height of the head rest is to be adjusted. A cylindrical guide member (7, 41) serves to guide the adjusting movement of the supporting rod (5).
