Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to an automobile headrest.

b. Conventional Technology As a conventional automobile seat, there is, for example, one shown in FIGS. 6 and 7. The vehicle seat 51 includes a seat cushion 52 on which an occupant is seated and a seat back 53 which receives the back of the seated occupant, and a headrest 54 whose vertical position can be adjusted is attached to the upper part of the seat back 53. There is. This headrest 54 is a seat back
It is attached to the seat back 53 by inserting a resin-made grommet 55 as shown in FIG. 8 into a support member (not shown) fixed to 53 and inserting a headrest stay 56 into the grommet 55. ing. A cover member 57 as shown in FIG. 9 is attached to the lower portion of the headrest main body 54a, and the cover member 57 conceals the skin end portion of the headrest main body 54a.

c. Problem to be Solved by the Invention However, in the above-described conventional headrest 54, a plurality of notches (notches) 58 provided in the outer peripheral portion of the headrest stay 56 are provided with a locking device (not shown) in the grommet 55. ) To adjust the height of the headrest body 54a, the headrest body 54a
If the cover member 57 on the headrest main body 54a side and the grommet 55 on the seat back 53 side are designed to be flush with each other when installed at the lowermost stage, the cover member 57 is grommet due to variation in dimensional accuracy of the notch position. Even if it interferes with 55, notch 58 of headrest stay 56 is still grommet
There was a problem that it could not be locked because it did not fit with the locking device in 55. Therefore, conventionally, the notch 58 of the headrest stay 56 is configured to be fitted with the lock device immediately before the cover member 57 and the grommet 55 interfere with each other, but according to this, even in the lowermost stage of the headrest main body 54a. As shown in FIG. 7, a part of the headrest stay 56 could be seen to flicker from the outside, possibly impairing its appearance.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle headrest capable of solving the above-mentioned drawbacks.

d. Means for Solving the Problems In order to solve the above-mentioned problems of the related art, in the present invention, a cover member is attached to the lower surface of the headrest main body on which the headrest stay is projected, and a grommet is provided on the upper part of the seatback. Provided in a headrest of an automobile in which the headrest stay is inserted into the grommet to attach the headrest body to the seat back in a state where the position of the headrest can be adjusted in the vertical direction, the headrest stay is provided at a position of a cover member protrudingly arranged. While providing a protrusion, a recess is provided in the head of the grommet, and when the headrest main body is installed at the lowest stage, the protrusion of the cover member is inserted and arranged in the recess of the grommet. .

e. Embodiment Hereinafter, the present invention will be described in detail based on the illustrated embodiment.

1 to 5 show an embodiment of the present invention. In the drawings, reference numeral 1 is an automobile seat disposed in a front portion of an interior of an automobile, etc., and this automobile seat 1 is attached to a vehicle body. Seat cushion 2 and the seat cushion 2
The seat back 3 is provided upright on the rear end of the vehicle. Further, a headrest 4 whose vertical position can be adjusted is attached to the upper portion of the seat back 3.

The headrest 4 includes a headrest main body 5 for receiving the head of an occupant and headrest stays arranged on the lower surfaces of the headrest main body 5 on both left and right sides.
6, 6 and a cover member 7 for concealing the skin end portion of the headrest body 5. The headrest stay 6 is formed to have a length that penetrates the lower surface of the cover member 7 and projects further downward as shown in FIG. ing. Further, a plurality of notches 8 that are fitted (latched) with a locking device described later are provided inside the outer peripheral portion of the headrest stay 6 at regular intervals along the axial direction. Further, a protrusion 9 having a substantially square planar shape is formed at a position of the cover member 7 where the headrest stay 6 is arranged so as to project.

On the other hand, a resin grommet 10 is attached to the upper portion of the seat back 3 at a position corresponding to the headrest stay 6 by inserting a shaft portion described later into a support member 11 in the seat back 3. As shown in FIG. 3 and FIG. 5, the grommet 10 is composed of a head 12 having a substantially square shape in a plane and protruding from the upper surface of the seat back 3, and a shaft portion 13 arranged in the seat back 3. In addition, an insertion hole 14 into which the headrest stay 6 is inserted and a locking device 15 are provided therein.

On the upper surface of the head 12 of the grommet 10, a recess 16 of the same shape formed slightly larger than the outer diameter dimension of the projection 9 of the cover member 7.
Is provided, and the lower portion of the protrusion 9 can be smoothly inserted into the recess 16. Also a locking device
15 is provided in such a position that the lower portion of the protrusion 9 is disposed inside the recess 16 and does not contact the bottom surface of the recess 16 when the notch 8 of the headrest stay 6 located at the uppermost stage is fitted. The protrusion 9 of the cover member 7 is a grommet
The notch 8 and the locking device 15 before contacting the head 12 of 10
Are fitted to each other, and the headrest main body 5 at the lowermost position is locked.

In the headrest 4 configured in this way, in order to avoid the problem that the cover member 7 is not locked even if the cover member 7 interferes with the grommet 10 due to the variation in the dimensional accuracy of the position of the notch 8 of the headrest stay 6 as in the conventional case, the headrest main body 5 is When installed in the lowermost stage, the notch 8 of the headrest stay 6 is fitted and locked with the locking device 15 before the protrusion 9 of the cover member 7 contacts the head 12 of the grommet 10. Therefore, a gap is created between the protrusion 9 of the cover member 7 and the head 12 of the grommet 10, and a part of the headrest stay 6 is exposed.
As shown in FIGS. 3 to 3, since the headrest stay 6 is inserted and arranged in the recess 16 of the head 12, the headrest stay 6 is attached to the head 12 of the grommet 10.
It is covered by and cannot be seen from the outside.

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example, Various modifications and changes are possible based on the technical idea of this invention.

For example, in the above-described embodiment, the projection 9 of the cover member 7, the head 12 and the recess 16 of the grommet 10 are formed in a substantially rectangular shape in a plane, but a plane circle or another shape is appropriately selected according to the vehicle type to be applied. It goes without saying that you can do it.

f. Effect of the Invention As described above, the vehicle headrest according to the present invention is
While the protrusion is provided at the position of the cover member where the headrest stay is arranged to project, the recess of the head of the grommet is provided, and when the headrest main body is installed at the lowest stage, the protrusion of the cover member is inside the recess of the grommet. Since it is configured to be inserted in the headrest stay, it is possible to securely lock the headrest main body at the lowermost position even if the dimensional accuracy of the notch position of the headrest stay varies.
A part of the headrest stay is no longer visible from the outside, and a good appearance is obtained. Moreover,
The headrest of the present invention uses no new parts,
Since this is a simple structure in which only the shapes of existing constituent members are changed, the cost of parts is not increased, and it is economically advantageous.
