The present invention relates to a head rest made of a structure for selectively shifting the position of the head rest covering the front view of the passenger in the rear seat of the vehicle.

Two seats are typically installed in the front seat of a car, one for driving and the other for passengers, as shown in Figs. 1 and 2 on the upper part of the back plate provided in the seats. Headrests (2) were installed for the purpose of preventing accidents that may occur in a car crash.

The hestress (2) is coupled to the seat (1) guides (3) for adjusting the height in accordance with the physical conditions of the occupant, and is located in the back of the neck of the occupants to support the head bent back by a sudden impact It consists of the cushion part 4 which absorbs a shock.

These headrests are typically held in the state of inserting the guide rest of the headrest into the guide hole formed in the upper end of the seat, if necessary hold the cushion portion and move to the desired height of the seat formed on the side of the guide stand We used in state to cause lock piece to hang.

However, in the process of using the headrest, the occupant in the rear seat felt frustrated because the front vision was obscured by the headrest of the front seat. There was a case of securing a forward field of view. In addition, when the removed headrest is to be installed on the back of the seat again, there is a hassle to insert the guide in accordance with the guide tube of the back, and there is a problem that it is not easy to keep the headrest separated from the seat well.

In order to solve such a conventional problem, as shown in FIG. 3, in the headrest for a vehicle installed above the backrest 20 of the seat to support the head and neck of the occupant, the top of the backrest 20 has a rectangular space. A fixed rod (1) and a guide rod (2) having vertical grooves (1A) were vertically formed on both sides of the space portion (20A), respectively, to form a portion (20A).
