Inclinable headrest

Abstract

A headrest inclinable relative to headrest stay(s), which is formed by a foaming process. The headiest has elongated hole(s) formed in the bottom thereof, with the headrest stay(s) extending outwardly through the elongated hole(s). Defined within the elongated hole(s) is an injected point where a liquid foaming agent has been injected into a headrest trim cover assembly during foaming process. Thus, in a resulting headrest formed thereby, such injected point is not viewed from a bottom of the headrest, when the headrest is inclined relative to the headrest stay(s), thereby maintaining an aesthetic appearance of the headrest.

       3 . A headrest inclinable relative to at least one headrest stay, wherein said headrest comprises:
 a three-dimensional trim cover assembly including a wall disposed on one side of said headrest;   foam padding filled in said three-dimensional trim cover assembly;   at least one elongated hole formed in said wall of said three-dimensional trim cover assembly and also formed in a local area of said foam padding corresponding to said wall of said three-dimensional trim cover assembly so as to be recessed inwardly of the headrest, with an inner base ( 3 D) located at a depth of said at least one elongated hole;   an injection hole formed on said inner base ( 3 D) through which said foam padding was filled in said three-dimensional trim cover assembly;   a first portion of said at least one headrest stay being rotatably connected with said headrest within said foam padding;   a second portion of said at least one headrest stay extending from said inner base ( 3 D) of said at least one elongated hole and also extending through said at least one elongated hole to an outside of said one side of the headrest;   said at least one elongated hole permitting said second portion of said headrest to be movable therein relative to said first portion of said at least hole headrest stay, thereby allowing the headrest to be inclinable relative to said at least one headrest stay; and   wherein a localized part of said foam padding, which corresponds to said injection point (P), is located at said inner base ( 3 D) of said at least one elongated hole, while being distant from said second portion of said at least one headrest stay that extends from said inner base ( 3 D).   
   
   
       4 . A headrest inclinable relative to at least one headrest stay, said headrest having at least one elongated hole formed in one side thereof, said at least one elongated hole having an inner base ( 3 D) defined at a depth thereof, wherein said headrest is formed by a foaming process comprising the steps of:
 providing a three-dimensional trim cover assembly preformed in a predetermined shape conforming to a contour of said headrest, with said at least one rigid stay being placed in said three-dimensional trim cover assembly such that a first portion thereof is located within said three-dimensional trim cover assembly, while a second portion thereof projects outwardly from said three-dimensional trim cover assembly;   providing a foaming die including a die portion adapted to form said at least one elongated hole, said die portion including a die surface for forming said inner base of said at least one elongated hole, a first through-hole ( 6 ), and a second through-hole ( 7 ),   wherein said first and second through-holes open to said die surface in a spaced-apart relationship to each other and extend through said die portion;   placing said three-dimensional trim cover assembly in said foaming die, so that said second portion of said at least one headrest stay extends through said first through-hole of said die portion;   injecting a liquid foaming agent through said second through-hole into an inside of said three-dimensional trim cover assembly;   whereupon an injection point (P) for said liquid foaming agent is established at said second through-hole ( 7 ); and   curing said liquid foaming agent into an increased mass of foam padding which is filled in said three-dimensional trim cover assembly in integral manner, so that said at least one through-hole is formed by said die portion in said foam padding;   wherein said headrest comprises:   said three-dimensional trim cover assembly including a wall disposed on said one side of said headrest;   said foam padding filled in said three-dimensional trim cover assembly;   said at least one elongated hole formed in said wall of said three-dimensional trim cover assembly and also formed in a local area of said foam padding corresponding to said wall of said three-dimensional trim cover assembly so as to be recessed inwardly of the headrest, with said inner base ( 3 D) located at a depth of said at least one elongated hole;   said first portion of said at least one headrest stay being rotatably connected with said headrest within said foam padding;   said second portion of said at least one headrest stay extending from said inner base ( 3 D) of said at least one elongated hole and also extending through said at least one elongated hole to outside of said one side of the headrest; and   said at least one elongated hole being of such configuration that allows said second portion of said the headrest to be movable therein relative to said first portion of said at least hole headrest stay, thereby allowing the headrest to be inclinable relative to said at least one headrest stay;   wherein a localized part of said foam padding, which corresponds to said injection point (P), is located at said inner base ( 3 D) of said at least one elongated hole, while being distant from said other portion of said at least one headrest stay that extends from said particular inner base ( 3 D).
