Description

[Detailed Description of the Invention] The present invention relates to a headrest for a vehicle seat, and particularly to one in which the headrest is rotatable.

Conventionally, a headrest for a vehicle seat consists of a cushioning member covered by an outer skin, and a stay on the bottom side, and this stay is attached to the head side of the seat back of the seat so that it can move up and down. This headrest can only be adjusted in height in the vertical direction, and cannot be used as a headrest to prevent the vehicle from rolling when the occupant sleeps, or to prevent the vehicle from rolling when the vehicle takes a sharp curve. It could not be used as a preventive measure.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by making the entire headrest or the entire upper part rotatable in the front direction so that the side of the occupant's head can be held on the headrest. This will be explained in detail using

1 to 3 are simplified configuration diagrams showing one embodiment of a head rest for a vehicle seat according to the present invention. In the figures, numeral 1 denotes a flat fixing body, and as shown in FIG. A stay 3 is attached to the fixed body 1 so as to be movable up and down in a hole (not shown) provided in the seat back part 2, and is fixed by a tapping screw 4 or the like. The fixed body 1 is movable up and down by the stay 3. A head rest part 5 is positioned on the fixed body 1, and this head rest part 5 is rotatably connected to the fixed body 1 by a rotation mechanism 6. It is pivoted. The rotation mechanism 6 includes a boss 7 provided on the end side of the flat fixed body 1 and the boss 7.
The cylindrical body 9 is fixed to the bottom plate 8 of the head rest part 5 so that the cylindrical body 9 fits into the bottom plate 8 of the head rest part 5, and the nut 11 is fitted from the lower side through the hollow part of the boss 7, and the nut 11 is screwed into the threaded part 10 provided at the tip of the cylindrical body 9. Further, the bottom plate 8 is provided with a semicircular slit 13 extending in a circular shape with the cylindrical body 9 as a fulcrum. is slidably inserted. A pin 14 contacts the end of this slit 13, so that the rotation range of the headrest portion 5 can be set to approximately 90 degrees.

Therefore, according to the above configuration, the headrest portion 5
By rotating the headrest toward the rear and setting the headrest section 5 so that it is parallel to the surface side of the seat back section 2, it can be used as a normal headrest, and its height can also be adjusted freely. . Next, in order to prevent the occupant from rolling when the vehicle approaches a sharp curve, or to prevent the occupant from leaning to the side when sleeping, the headrest portion 5 should be moved toward the front. and rotate this head rest part 5 to the seat back part 2.
By keeping the head rest perpendicular to the seat, the head rest part 5 rotates around its end, so that it protrudes toward the surface of the seat back part 5, and this position corresponds to the side of the face part. Therefore, by leaning the side of the occupant's face against the side of the headrest portion 5, the above-mentioned rolling and tilting can be prevented, and the occupant's face can be prevented when the vehicle makes a sharp turn or when the occupant sleeps. It is possible to stabilize body retention. i.e. pin 1
4 is inserted into the slit 13, so this pin 1
4 and the slit 13, the head rest part 5 can be rotated in the right angle direction, so by properly using these parts, it can be used as either a normal head rest or a head rest for preventing rolling. Further, according to the headrest according to the present invention, by rotating the headrest part 5 in the front direction as shown in FIG. 3, the driver's rear view is not obstructed by the headrest part 5. , the driver's field of view can be widened, making driving easier.

In the present invention, the head rest part 5 is rotatable in a direction perpendicular to the front direction, and the head rest part 5 is rotatably held by the fixed body 1. Figure 4, 5th
As shown in the figure, when a fixed body 1 that holds the headrest part 5 is formed using a part of the headrest, and the upper headrest part 5 is rotated in the front direction by the part 1 of the headrest part. Also, the head side of the occupant may be held.

As explained above, according to the headrest for a vehicle seat according to the present invention, the whole or the entire upper side of the headrest is connected to the backrest surface 2a of the seat pack part 2.
Since a rotation mechanism is provided that can set the rotation position to a state parallel to the backrest surface 2a and a state perpendicular to the seatback surface 2a, the headrest can be used to prevent the occupant from rolling or tilting if necessary. It can be used as a headrest, ensuring the safety of passengers while driving and sleeping, and has the effect of widening the rear visibility.
