BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headrest for an automobile seat mounted on an upper portion of a backrest of the automobile seat and supporting an occupant's head.

[0002]

2. Description of the Related Art Conventionally, as a vehicle seat, a vehicle seat having a headrest attached to an upper portion of a backrest portion for supporting the head of an occupant has been employed. Such a vehicle seat is configured, for example, as shown in FIG. In FIG. 4, an automobile seat 1 includes a seat portion (not shown) on which an occupant of the automobile sits and a backrest 2 on which the occupant leans. The headrest 3 is attached to the vehicle.

According to the vehicle seat 1 configured as described above, in order to support the occupant's neck to the side when the occupant sleeps or the like, the detachable detachable structure is provided separately from the headrest 3. The necklace 4 of the type, the support 3a of the headrest 3
To support the occupant's neck.

[0006] As shown in FIG.
, A substantially U-shaped necklace 5 is rotatably attached to the vehicle, and when used, the U-shaped tip of the necklace 5 is pulled out so as to extend to both sides of the occupant's head. There is also known an automobile seat 1 'which is flipped up so as to face.

[0005]

However, in the vehicle seats 1 and 1 'constructed as described above,
In the case of the vehicle seat 1 shown in FIG. 4, since the necklace 3 is a separate body, there are problems that the mounting operation is troublesome and time-consuming, and that a storage space is required when not in use. Further, in the case of the automobile seat 1 'shown in FIG. 5, the operation at the time of use is simple and short, but when not in use, the headrest 3 is flipped up on both sides, so that the visibility to the rear is reduced. In addition to being obstructed, the field of view from the rear is narrowed, and there is a problem that the livability is reduced.

[0006] In view of the above points, the present invention provides an easy and quick operation for using a necklace, and does not obstruct the view when stored when not in use.
Accordingly, it is an object of the present invention to provide a headrest for an automobile seat that does not impair the livability.

[0007]

In order to achieve the above object, a headrest for an automobile seat according to the present invention is provided.
A base portion fixedly attached to the upper portion of the backrest of the vehicle seat, and a necklace portion attached to the base portion so as to be slidable in the front-rear direction and formed so that the left and right protrude forward. A headrest portion above the necklace portion and supported rotatably around a rotation shaft extending in the left-right direction fixed to the base portion, and the headrest portion includes a neckrest portion. At the lower position in contact with the upper surface of the headrest, the front edge of the headrest portion coincides with the tip of the necklace portion, and the headrest portion is moved to the upper position where the front edge is lifted upward from the lower position. When brought in, the neckrest part is moved forward in conjunction with the rotation of this headrest part, and it is characterized by projecting to both sides of the occupant's head That.

[0008]

According to the above construction, when the neckrest portion is not used, the headrest portion is located at the lower position, and the front edge thereof coincides with the tip of the necklace portion. The front edge supports the occupant's head from behind and functions as a headrest. In addition, since the necklace portion is located below the headrest portion, the neckrest portion does not protrude to the side or upward of the headrest portion, and thus obstructs the rear view or narrows the rear view. Since there is no
The livability is improved.

When the necklace is used,
The headrest is brought to the upper position by simply lifting the front edge of the headrest, and in conjunction with this, the neckrest is moved forward, so that the neckrest moves forward on both sides. The protruding tip will support the occupant's head from both sides, thus functioning as a necklace, with the bottom of the headrest facing forward and supporting the occupant's head from behind. Therefore, the operation at the time of using the necklace is performed in a short time by simply lifting the front edge of the headrest portion and rotating the headrest portion. become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. FIGS. 1 to 3 show an embodiment of a headrest of an automobile seat according to the present invention. A headrest 10 of the automobile seat is a backrest (not shown) on which an occupant of the automobile seat should lean. So that it can be attached to the top. The headrest 10 includes a base portion 11 (see FIG. 3) fixedly attached to an upper portion of a backrest portion of an automobile seat;
A neck portion 12 is attached to the base portion 11 so as to be slidable in the front-rear direction, and is formed so that left and right protrude forward. And a headrest portion 13 supported rotatably about a rotation shaft extending in the left-right direction and fixed to the head.

The base portion 11 includes a necklace portion 12.
As a slide guide for
It is fixed to a column 13a that can be inserted into and fixedly held in the backrest of the vehicle seat.

The headrest portion 13 is rotatably supported by a rotating shaft 15 extending in the left-right direction with respect to a supporting member 14 attached to the upper end of the column 13a. Arc-shaped engaging member 16
The engagement claws 18 mounted on the support member 14 and urged by the springs 17 fit into the notches 16a and 16b provided inside the engagement member 16, The rotation of the headrest portion 13 can be temporarily locked.

Further, the armrest 12a fixed to the headrest portion 13 is connected to the headrest portion 13 and the neckrest portion 12 via a link 19.
, The necklace portion 12 can be slid back and forth in conjunction with the rotation of the headrest portion 13.

In this case, the positional relationship between the headrest portion 13 and the neckrest portion 12 is such that when the neckrest portion 12 is in the retracted position, as shown by the solid line in FIG. It is retracted backward so that it does not project to both sides of the occupant's head, and the headrest 1
Reference numeral 3 is adapted to contact the upper surface of the necklace portion 12, and its front edge coincides with the front edge of the necklace portion 12. When the necklace portion 12 is in the use position, the front end of the necklace portion 12 is pulled out so as to protrude to both sides of the occupant's head, as indicated by a chain line in FIG. Function as the headrest 1
3 has its front end raised and its bottom surface facing forward. At this position, the engaging claw 18 on the supporting member 14 is engaged with the notch 16b of the engaging member 16 so that the headrest portion 13 is moved. It can be locked at the position shown by the chain line.

The vehicle seat 10 according to the present invention is configured as described above. When the necklace portion 12 is not used, the headrest portion 13 is located at a lower position as shown by a solid line in FIG. The front edge of the headrest portion 13 and the front edge of the neckrest portion 12 function as a headrest by supporting the occupant's head from the rear because the front edge coincides with the front end of the necklace portion 12. At this time, since the neckrest portion 12 is located below the headrest portion 13, it does not protrude to the side or upward of the headrest portion 13, so that the view of the rear is obstructed, and There is no such thing as narrowing the field of view.

Here, when the neckrest portion 12 is used, the headrest portion 13 is brought to an upper position shown by a chain line by an operation of merely lifting the front edge of the headrest portion 13, and the arm 12a and the link 19 are moved. The necklace portion 12 is moved forward in conjunction with this. As a result, the front end of the neckrest portion 12 projecting forward on both sides thereof supports the occupant's head from both sides, and thus functions as a necklace, and the bottom surface of the headrest portion 13 faces forward. Thus, the head of the occupant is supported from behind, and functions as a headrest.

[0017]
