Supporting structure for head rest

摘要

In a supporting structure for a head rest that includes a pair of tubular brackets (1) fixed inside a seat back, a pair of support bodies (11) fitted in the brackets and formed with insertion holes (12), and a pair of stays (21) provided at the head rest end and slidably fitted in the insertion holes of the support bodies, there are provided on outside faces of a respective support body (11) a plurality of flexible vanes (19) extending in perpendicular directions to an axial direction of the support body and formed in a spacing manner, the flexible vanes (19) having outside dimensions set larger than inside dimensions of an associated bracket (1) so that in cases such as when sliding the head rest to be positioned in level of height, it can be out of apprehension that the support body (11) might unexpectedly rattle in the bracket (1) and give rise to an uncomfortable feeling to the sliding of head rest.
