or is formed.

The upper end portion 31 of the tin stay 3 is fitted into four mounting grooves 10a formed in the shallow metal container 10 and fixed thereto.

(Problems to be Solved by the Invention) However, in such a conventional two-rest for automobiles, (1) The upper end portion 31 of the Nischy 3 is a hollow core l.
Therefore, in order to ensure safety, the thickness of the band 2 should be made thicker to the extent that the end portion 31 of the stay 3 is on the surface of the hollow core 1 and has a strong regularity. (2) The upper end 31 of the stay 3 is attached to the surface 1a of the hollow core l to which the upper end 31 of the stay 3 is fixed. It is attached to the stay 3 or the upper end of the seat backrest so as to face the rear seat side, but since it is fixed to the upper end 31 of the stay 3 or to the outside of the hollow core 1, the head of the rear passenger etc. When hitting the headrest due to an impact, the head etc.
There was a problem in that there was a risk of injury due to the collision with the upper end 31 of the stay 3, which has high elasticity.

The present invention was created by focusing on these conventional problems, and it is possible to reduce the thickness of the bat while ensuring safety.
Overall, the volume of the butt is small, thereby reducing the amount of varnish, and when the head of a rear passenger hits the headrest due to a collision, etc. The purpose of this product is to provide a headrest for automobiles that does not hit the vehicle.

(Means for Solving the Problems) In order to achieve the above object, the gist of the present invention is that a hollow core is formed by combining two shallow metal containers, and the hollow core is connected to a bat. In the headrest for an automobile, the upper end of the inverted U-shaped stay for attaching the headrest i body consisting of the hollow core body and the punt to the upper end of the seat back rest is sandwiched between the two shallow containers. A recessed portion is formed symmetrically in the shallow container, and is located in the hollow core body from the surface of the shallow container toward the inside of the hollow core body, and between the bottoms of the opposing recessed portions. The headrest for an automobile is characterized in that the upper end of the stay is clamped and fixed.

(Function) In the above automobile headrest, since the upper end of the stay is located inside the hollow core body, the thickness of the pad can be made thinner, and the head of the occupant can be attached to the upper end of the stay or It is safe because it does not hit the vicinity.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Note that the same parts as in the conventional example are designated by the same reference numerals.

Convex portions 12 and concave portions 13 are alternately formed on the opening r:J edge of the peripheral wall 11 of each shallow metal container 10, and the convex portions 12 and concave portions 13 of one shallow metal container 10 are the same as those of the other metal. It is capable of engaging with the concave portion 13 and the convex portion 12 of the shallow container 10, respectively.

In addition, in each shallow metal container lO, some of the protrusions 12
A locking hole 14 is bored in the hole 14, and an insertion piece 15 inserted into the locking hole 14 is formed in some of the recesses 13.
is installed protrudingly.

Between the shallow containers to and 10, there is a surface 10a,
from loa toward the inside of the hollow core body 1 ;) Insertion part Is,
It is formed symmetrically with two X13 pieces, and the stay 3
When the upper end portion 31 of the container 10 is inserted between the two J-shaped shallow containers 10 and positioned inside the hollow core 1, the opposing fitting portions! The bottom part 1f of 6°16 (the upper end part 3 between a and lea)
