The present invention relates to a headrest, and more particularly, to a headrest configured to be movable to the left and right of the headrest attached to the upper back of the driver's seat and the passenger seat of the vehicle.

The head rest is attached to the upper back of the driver's seat and passenger seat to support the occupant's head to increase the ride comfort, and prevents the occupant's neck from falling backward in the event of a vehicle crash. The headrest is a high-back seat type (hlgh-back seat) type formed integrally with the back of the seat, but as shown in FIG. 1, the rod 36 is attached to the lower part of the headrest 35. It is known to adjust the height of the headrest 35 by attaching and detaching the clamp 33 after inserting 37 into the insertion hole formed in the upper surface of the backrest 31 of the seat.

However, as described above, the headrest 35 of the present structure has a structure capable of adjusting only the height of the headrest 35 from the backrest 31 of the seat, so that the occupant moves the head outwards or inwards during a long vehicle ride. Even when you want to tilt, the headrest 35 does not move in the left and right directions, so it is inconvenient because it cannot support the head effectively. When a situation such as a sudden stop or a collision of the vehicle occurs, the neck part is smoothly supported. There was a lot of injuries, etc.

The object of the present invention is to solve the above-mentioned problems in the prior art by moving the headrest in the left and right directions so that the occupant can properly support even if the head tilted outwards or inwards during a long vehicle ride, It demonstrates in detail with drawing.

Headrest 30 according to the present invention, as shown in Figure 2, in the headrest to be installed on the upper back 45 of the seat by the rods 41, 42 attached to the lower both sides, as a cushioning material Rectangle case interpolated into the outer shell (5) consisting of a rectangular case having a slot (11) having grooves (10A, l0B, l0C) at the center and both sides at the top and a slot (12) having a long hole (10D) at the bottom ( 10) and. The leaf springs are inserted into the case 10 by the protrusions 21 and 22 formed on the upper and lower sides, and the leaf springs engaged with the grooves 10A, l0B, and l0C of the case 10 on one side of the upper protrusion 21. The block body 20 with 25 is made into a main structure.

The case 10 is inserted into the outer shell 5 made of a cushioning material such as foam rubber or sponge to form a moving space to the left and right sides of the block body 20, and to guide and support the movement of the block body 20. The slots 11 and 12 are formed in the upper and lower lengths thereof, and the semi-circular grooves are formed in the upper slots 11 so that the leaf springs 25 of the block body 10 are locked to the center and both sides thereof. 10A, L0B, and L0C are formed, and a long hole 10D is formed in the lower slot 12 for the movement of the rods 41 and 42 protruding to both lower sides of the block body 10.

When the block body 20 is inserted into the case 10 and inserted into the upper back 45 of the seat by interpolation with a third degree, the case 10 and the shell 5 move to the left and right according to the purpose of use. In the upper and lower portions, protrusions 21 and 22 having cross-sectional shapes corresponding to the slots 11 and 12 of the case 10 are formed, and the protrusions located above the protrusions 21 and 22 are formed. The plate spring 25 bent in a semicircle is attached to the middle portion of the case 21 so as to be engaged with the grooves 10A, l0B and l0C of the case 10.

On the other hand, the case 10 is made of a divided body so that the front and rear surfaces are separated to facilitate the fabrication and coupling with the block body 20.

An operation relationship of the headrest 30 according to the present invention having the configuration as described above will be described with reference to FIG. 4.

Figure 4 (a) is a view showing a state of use of the subject innovation in accordance with the conventional state, in the above state the leaf spring 25 of the block body 20 is located in the upper portion of the case 10 The headrest 30 is thereby fixed to the back of the backrest 45 by being latched in the middle recess 10B of the back.

When the occupant wants to turn his head to the left in the above state, the headrest 30 is moved to the left side by pushing the headrest 30 from the right side. When the headrest 30 is pushed from the right side, the headrest ( 30, the inner block body 20 is fixed to the upper back 45 of the seat by the rods 41 and 42, so that the outer shell 5 and the case 10 are relatively moved so that As shown in b), the headrest 30 moves to the left side, and accordingly, the headrest 30 flows because the leaf spring 25 of the block 20 is engaged with the groove 10C located on the right side of the case 10. Without moving to the left side of the back 45.

In addition, when the headrest 30 is positioned to the right side, the left side of the headrest 30 is pushed so that the leaf spring 25 of the block body 20 and the recess 10A located on the left side of the case 10 are engaged. It simply completes.

The present invention implemented as described above is configured to move the headrest 30 to the left and right, so that even if the occupant tilts his head during a long ride, the head restrains the head appropriately, thereby improving the riding comfort, and when sleeping in the car. Edo can move the position of the headrest to the left and right to increase the comfort.

Claims (1)
