Benefits of technology

[0008]In view of the above-stated drawbacks, it is a purpose of the present invention to provide an improved inclinable headrest for automotive seat, which is devoid of the afore-said injection hole in the bottom side of the headrest, to thereby maintain aesthetic appearance of the headrest itself.

Problems solved by technology

This undesired problem also arises for backward inclination of the headrest; namely, with the headrest inclined backwardly relative to the headrest stays, the injection hole is then clearly viewed from the front side of vehicle.
Such appearance of injection hole is objectionable and impairs the aesthetic appearance of headrest.

Embodiment Construction

[0020]FIG. 1 shows an inclinable headrest (HR) for use on automotive seat in accordance with the present invention. FIG. 2 shows a foaming die apparatus for forming such inclinable headrest (HR), and FIGS. 3 and 4 are illustrative of a foaming process using that foaming die apparatus to produce the inclinable headrest (HR).

[0021]The headrest (HR) is depicted in the FIG. 1 to have a pair of headrest stays (S) and (S1) which extend downwardly from the bottom side thereof and are fixedly mounted on the top of a seat back (SB) of an automotive seat. As shown, fromed in the bottom of the headrest (HR) are a pair of elongated holes (1) and (2) through which the two headrest stays (S) (S1) pass, respectively, into the inside of the headrest (HR).

[0022]As indicated by the dotted lines in FIG. 1, two headrest stays (S) (S1) are connected integrally with a horizontal axis element (S2) within the headrest (HR). While not clearly shown, the headrest (HR) itself is rotatably coupled with such ho...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a headrest which can be mounted via a headrest stay(s) on an automotive seat and is inclinable forwardly and backwardly relative to the headrest stay(s). Hereinafter, this headrest shall be referred to as “inclinable headrest” for simplicity. In particular, the invention is directed to an inclinable headrest of this kind which is formed by a foaming process wherein a liquid foaming agent is injected into an inside of a trim cover assembly preformed to have a predetermined contour of headrest, and then, the liquid foaming agent is cured to form an increased mass of foam padding filled in that trim cover assembly.[0003]2. Description of Prior Art[0004]In most cases, a headrest for use on automotive seat is formed through a foaming process which basically consists of the steps of performing a three-dimensional trim cover assembly in a predetermined shape of headrest by sewing together a plu...
