The front edge supports the occupant's head from the rear and functions as a headrest. Moreover, since the necklace part is located below the headrest part, it does not project laterally or upwardly from the headrest part, and therefore it hinders the rear view or narrows the rear view. Since there is no such thing, livability is improved.

When the necklace part is used, the headrest part is brought to an upper position by merely lifting the front edge of the headrest part, and in conjunction with this, the necklace part is moved forward. As a result, this necklace part supports the occupant's head from both sides by the tips projecting forward on both sides, and thus functions as a necklace, and the bottom surface of the headrest part moves forward. The head of the occupant will be supported from the rear to function as a headrest.Therefore, when using the necklace, lift the front edge of the headrest and rotate the headrest. It can be done in a short time by a simple operation that only moves it.
