Claim:
A headrest adapted to be mounted on a vehicle seat, comprising: a generally inverted-U-shaped frame provided in said headrest, said generally inverted U-shaped frame having, defined therein, a horizontal frame portion disposed at an upper side of said headrest, and a pair of spaced-apart vertical frame portions extending vertically and continuous from said horizontal frame portion in a direction downwardly of the headrest; a pair of spaced-apart headrest stays defined integrally in two lower portions respectively of said pair of spaced-apart vertical frame portions, said pair of spaced-apart headrest stays being adapted to be mounted in said vehicle seat; a single impact absorption bar element having two endpoints that are fixedly connected to said pair of spaced-apart vertical frame portions in such a manner as to extend transversely of said pair of spaced-apart vertical frame portions, while being disposed under, spaced apart from, and substantially parallel to said horizontal frame portion, said impact absorption bar element being of a property prone to deformation only by an excessive great load applied thereto from said head of the seat occupant in case of a rear-end collision or a factor for causing said excessive great load; a headrest body including a foam padding filled therein; wherein a substantially midway point of said impact absorption bar element thereof is a recessed or cut-away region, thereby defining a readily deformable region in said substantially midway point, wherein said horizontal frame portion, said pair of spaced-apart vertical frame portions, and said single impact absorption bar element are embedded integrally in said foam padding of said headrest body, while said pair of spaced-apart headrest stays extend outwardly from said headrest body.
