Abstract
A headrest for motor vehicle seats comprising a resilient body incorporating a molded plastic material supporting framework connected in a frictionally rotatable way to a bearing structure. The supporting framework has an integral tubular base directly overmolded on the transverse member of the bearing structure, so as to perform a mutual rotatable coupling with interference without any need of auxiliary friction members.
Claims10
A headrest for a motor vehicle seat having a backrest, comprising a resilient body incorporating a moulded plastic material supporting framework, and a bearing structure including a pair of rods to be connected to said seat backrest and a cylindrical transverse member rigidly interconnecting said rods, wherein frictionally rotatable connecting means are provided between said transverse member and said supporting framework to selectively adjust inclination of said resilient body relative to said rods, said supporting framework having an integral tubular base with a cylindrical cavity which is directly overmoulded onto said transverse member of said bearing structure, upon forming said supporting framework, so as to provide mutual interference rotatable coupling between said tubular base and said transverse member, defining said frictionally rotatable connecting means.
A method for manufacturing of a headrest for a motor vehicle seat having a backrest, comprising a resilient body incorporating a moulded plastic material supporting framework, and a bearing structure including a pair of rods to be connected to said seat backrest and a cylindrical transverse member rigidly interconnecting said rods, and frictionally rotatable connecting means between said transverse member and said supporting framework to selectively adjust inclination of said resilient body relative to said rods, said method comprising the steps of overmoulding said supporting framework on said transverse member so as to form an integral tubular base of said supporting framework which encloses said transverse member and performs therewith an interference rotatable coupling defining said frictionally rotatable connecting means.
