Generally, a seat of a vehicle is provided with a headrest. The headrest supports the head of the occupant so that the headrest can be mounted in a comfortable posture. In addition, And serves as a safety device for protecting the head of the user.

A typical headrest is formed by a cushioning material of sponge or similar material and is provided with a support rod for detachably fitting to the seat of the vehicle at the lower side and is provided with a leather or fabric sheet such as natural or synthetic leather sheet or the like is wrapped around the cushioning material.

The headrest of a typical headrest is mainly made of leather on which a cut-out is formed. The head rest is manufactured by pushing the cut-out opening, pushing the cushioning material therebetween, and sealing the incision.

In this case, since the maximum opening area of the incision is relatively small compared to the transverse area of the cushioning material, in order to insert the cushioning material, considerable force is applied to the incision opening to open the incision opening. . Accordingly, in the above procedure, both ends of the cutter, which are subjected to a relatively large force, are often broken.

In addition, when the headrest is used for a long period of time, frequent contact with the occupant's head may occur, causing the finish material to be easily damaged, and the finish material may be contaminated by dust or other foreign matter. However, a conventional headrest is a one-piece type in which a cushioning material and a finishing material are coupled to each other. When such a problem occurs, the entire headrest needs to be replaced.

As a technique for solving the above-mentioned problem, in the registration practice of Korean Patent Application No. 20-0436650, a separate cover is provided on the headrest to prevent contamination of the headrest, so that the headrest can be overlaid on the headrest A seat cover for a vehicle headrest is disclosed.

Wherein the headrest cover includes a rod having a pair of elongated elongated rods, the rod being provided with a rod extending in a straight line, the rod having a space formed by horizontally extending a coupling portion formed by overlapping an upper portion of the rod, And the other rod is provided with a pair of protrusions protruding outward at regular intervals and a ring is formed at the end of the rod, and at the opposite end of the rod on which the ring is formed, And the rod is fixedly connected to the headrest by inserting the rods extending in a straight line into the space and positioning the connecting bars of the headrests in the projections and then fastening the rings. .

However, although the above-mentioned technique can prevent the headrest from being contaminated by covering the headrest, it can not be applied to the manufacture of the headrest, and the problems that arise in the conventional manufacturing process still can not be solved .
