Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a headrest that is attached above the seat back of a vehicle seat or the like.

[Prior Art] A headrest for supporting the head of an occupant is attached to a vehicle seat above the seat back. Some headrests include height-adjustable headrest pads for supporting the occupant's head.

Some headrests of this type have a structure in which a headrest stay is fixed to a seat bag, and a headrest pad is supported in a variable height on the headrest stay via a vertically internally sliding headrest insert. (Jitsugan No. 60-67498).
In a headrest with this type of structure, for example, as shown in FIG. The headrest pad 10 is variably supported, thereby allowing the headrest pad 10 to be adjusted in height. The clip 14 is inserted through the notch 18A of the insert clip portion 18 and fitted into the headrest stay 16.

By the way, the headrest pad 10 in which the headrest insert 12 is incorporated is foam-molded from urethane, and the molding is carried out by setting the headrest insert 12 in a foaming mold.

However, in the headrest having the above structure, since the notch 18A for attaching the clip is formed in the headrest insert 12, it is necessary to prevent urethane from entering the notch 18A during molding of the headrest pad 10, as shown in FIG. As shown, the notch 18
It was necessary to have a configuration in which the headrest pad 10 was exposed to the outside of the headrest pad 10, or to seal the notch 18A with a sealing material such as tape before molding. For this reason, a portion of the headrest insert 12 protrudes outward from the headrest pad 10, resulting in a poor appearance or an increase in the number of parts, resulting in higher costs.

[Problems to be solved by the invention] Taking the above facts into consideration, the present invention does not have a structure in which a part of the headrest insert is exposed outside the headrest pad, and uses the sealing material as described above. It is an object of the present invention to obtain a headrest that can prevent molding material from entering into a headrest insert during molding of a headrest pad, with a configuration that is extremely inexpensive.

[Means for Solving the Problems] In the headrest according to the present invention, the headrest insert is built into the headrest pad, and the headrest insert is supported by the headrest stay via the engagement means, and the headrest insert is supported by the headrest stay via the engagement means. The headrest insert is configured to be relatively movable vertically along the headrest, and the headrest insert is composed of a hollow upper body member and a lower body member that are separable from each other, and the upper body member includes the engaging portion. means is provided in a state protruding toward the lower main body member, and the engaging means includes a holding member that slides while holding the head rest stay when the head rest moves relative to the head rest, and a holding member that slides while holding the head rest stay, and a holding member that slides while holding the head rest stay, and a holding member that slides the head rest while holding the head rest stay. and a holding member for holding the position after the relative movement, and the lower main body member is characterized by being provided with a recess into which the engaging means is inserted.

[Function] According to the above structure, the headrest insert built into the headrest pad is composed of a hollow upper body member and a lower body member that are separable from each other, and the upper body member is provided with an engaging means. protrudes toward the lower body member, and the lower body member is provided with a recess into which the engagement means is inserted. Therefore, with the engaging means inserted into the recess, the upper body member and the lower body member are integrated, thereby forming a headrest insert. The height of the headrest is adjusted by vertically moving the headrest including the headrest pad incorporating the headrest insert constructed in this way relative to the headrest stay.

Here, when the headrest moves relative to the headrest stay, the holding member of the engaging means slides while holding the headrest stay. Therefore, the holding member performs a guiding function during relative movement of the headrest.

Also, once the height adjustment of the headrest is completed,
The holding member of the engagement means holds the headrest in the position after relative movement with respect to the headrest stay.

Therefore, by simply moving the headrest relative to the headrest stay, the supporting position, that is, the height, of the headrest to the headrest stay can be easily and stably adjusted.

Moreover, the above-mentioned engagement means is provided on the upper body member in a state of protruding toward the lower body member and is inserted into the recess of the lower body member, so that the opening such as a notch for attaching the engagement means can be attached to the headrest. There is no need to form the insert. Therefore, when molding the headrest pad, there is no need to use a sealant to close the opening, and moreover, it is possible to form the headrest pad in a shape that hides almost the entire headrest insert. Become.

As shown in FIG. 3, the clip 42 is formed of a spring material and bent into a substantially U-shape, and is inserted and held in the intermediate portion of the cylindrical portion 36 of the main body member 30 in the height direction. Both ends of the parallel portion 42A of this clip 42 are held between a holding portion 44 formed at the middle portion in the height direction of the main body member 30 and the tip of the guide protrusion 40, and are formed protruding from the holding member 44. It is locked by locking protrusions 44A and 44B. The intermediate portion of the parallel portion 42A of the clip 42 is pressed against the outer periphery of the support portion 26A of the headrest stay 26 by a biasing force, and the headrest insert 24 is supported by the headrest stay 26 by the biasing force.

Therefore, in the headrest 20, the headrest insert 24 is supported on the headrest stay 26 by the clip 42 in a variable height manner, so that the height of the headrest pad 22 can be adjusted. ing.

Next, the procedure for assembling the headrest 20 will be explained.

To assemble the headrest 20, first attach the main body member 30 of the headrest insert 24 to the headrest stay 26. The main body member 30 can be attached by inserting the tip of the support portion 26B of the headrest stay 26 into the cylindrical portion 36 so that the support portion 26B of the headrest stay 26 passes through the cylindrical portion 36 of the main body member 30.

After installing the headrest stay 26, use the clip 4.
2 is locked to the locking protrusions 44A, 44B of the main body member 30. This locking is done by the parallel portion 42A of the clip 42.
This is done by pushing the clip 42 downward into the cylindrical part 36 of the main body member 30 while pushing it open and inserting the support part 26B of the headrest stay 26 in between.

After attaching the clip 42, attach the main body member 28 to the main body member 30 and attach the headrest insert 24.
Assemble. The main body member 28 is assembled by arranging the main body member 28 so that the connecting portion 26A of the headrest stay 26 is sandwiched between the main body member 30 from above and below, and then fixing the main body member 28 to the main body member 30 with screws 34. do it. The main body member 28 assembled with the main body member 30 has the connecting portion 2 of the head rest stay 26 in the cavity 32 between the main body member 30 and the main body member 30.
6A, and the rib 38 is the head rest stay 2.
The guide protrusion 40 is slidably abutted on the connecting portion 26A of the headrest stay 26 in the height direction, and the guide protrusion 40 is slidably abutted on the support portion 26B of the headrest stay 26 in the height direction.
Further, the tip of the guide protrusion 40 is brought into contact with the clip 42, and the holding portion 44 of the main body member 30 holds the clip 4.
2 and hold it. Therefore, in this embodiment, the clip 42 can be reliably held within the headrest insert without separately providing a mounting member such as a screw.

The headrest insert 24 assembled in this manner is supported by the clip 42 in a variable height manner.

After the headrest insert 24 is assembled, the headrest pad 22 may be attached to the headrest insert 24 by adhesive or the like.

Note that the headrest pad 22 may be attached to the headrest insert 24, and the headrest stay 26 may be attached to a seat bag (not shown). The headrest stay 26 is attached by welding or inserting and fixing the tip end of the support portion 26B of the headrest stay 26 to the seat back frame. After the headrest stay is attached, the headrest 20 is placed above the seat back and is movable in the height direction by the support portion 26B of the headrest stay 26.

The head rest pad 22 is foam-molded from urethane with a pre-assembled head rest insert 24 set in a foam mold. Here, since the headrest insert 24 has the clip 42 arranged inward as described above, there is no open part as in the conventional case, so urethane does not enter into the headrest insert 24 when forming the headrest pad. As a result, the headrest pad 22 is shaped to hide substantially the entire headrest insert 24.

Therefore, conventionally, the headrest insert 2
The sealing material used to form the headrest pad 22 into a shape that hides substantially the entire headrest pad 22 is omitted, reducing the material cost. Further, since it is not necessary to assemble a sealing material, the number of man-hours is also reduced.

[Effects of the invention] As explained above, the headrest according to the invention is composed of a hollow upper body member and a lower body member in which the headrest insert is separable from each other. A state in which the engaging means is protruded toward the lower main body member, and includes a holding member that slides while holding the headrest stay during relative movement, and a holding member that holds the headrest in the position after the relative movement with respect to the headrest stay. Since the lower body member is provided with a recessed portion for allowing insertion of the engagement means, a part of the headrest insert does not need to be exposed outside the headrest pad, and the structure is inexpensive. This has the excellent effect of preventing molding material from entering into the headrest insert during headrest pad molding.

In addition to the above-mentioned effects, the headrest according to the present invention has the holding member perform a guide function when the headrest moves relative to the headrest stay, and the holding member holds the headrest at the position after the relative movement, so that the headrest can be moved easily. This has an excellent effect in that the support position, that is, the height of the head rest to the head rest stay can be easily and stably adjusted by simply moving the head rest relative to the rest stay.
