Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle headrest whose contact surface with the head is formed by a wadding pad which is softer and has a better feel than the headrest body.

[0002]

2. Description of the Related Art Conventionally, various types of headrests for vehicles such as automobiles have been proposed in which the contact surface with the head is formed of a wadding pad which is softer and has a better feel than the headrest main body and has a good feel. (For example, JP-A-4
-352906 and Japanese Utility Model Publication No. 3-34125)

However, in this type of conventional vehicle headrest, the wading pad fitting portion formed on the front surface of the headrest body is a shallow recess, and the wading pad is merely embedded in the recess. Therefore, there is a problem that a step is generated at the joint between the two and after the skin is covered, the step causes a highlight to appear on the design surface and remarkably impairs the external appearance. Since the occurrence of the problem becomes more remarkable, there is a problem that productivity and workability are deteriorated due to the requirement of strict dimensional control of the wadding pad and setting in the recess. Furthermore, since the conventional headrest body is made of a urethane pad that is harder than the wadding pad, there is a problem that it is not possible to achieve sufficient weight reduction and cost reduction.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and prevents a step from being formed at the joint between the headrest body and the wadding pad, thereby providing an excellent appearance. Provided is a vehicle headrest that is capable of easily performing mounting work without causing a step even if there is variation in the shape of the wadding pad itself, and further can achieve sufficient weight reduction and cost reduction. It was completed for the purpose of doing.

[0005]

SUMMARY OF THE INVENTION A vehicle headrest according to the present invention made to solve the above-mentioned problems is a wading pad fitting portion in which an opening edge is formed in an eaves-like engaging portion on at least a front surface of a headrest body. And a wadding pad that is softer than the headrest body is attached to the wading pad fitting portion by engaging the eaves-shaped engaging portion with the outer peripheral edge.

[0006]

When such a vehicle headrest is used in the same manner as the conventional vehicle headrest of this kind, the opening edge of the wading pad fitting portion formed on the front surface of the headrest body is formed in the eaves-shaped engaging portion. The wadding pad that is softer than the headrest body fitted and mounted in the wading pad fitting portion has its outer peripheral edge engaged with the eaves-shaped engaging portion, so that a step may occur at the joint between the two. There is no such thing and it becomes very well-formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the embodiment shown in the drawings applies the present invention to an automobile headrest of the type in which a headrest body separate from the seatback is mounted on the top of the seatback of the automobile seat with a stay suspended from the seatback. An example will be described in detail. 1 is a headrest body made of a bead foam of polyolefin resin such as polypropylene resin or polyethylene resin, 2 is a stay embedded in the headrest body 1, and 3 is formed on the front surface of the headrest body 1 with which the head contacts. Wading pad mating part,
Reference numeral 4 denotes a wading pad made of a synthetic resin foam softer than the headrest body 1 such as polyurethane foam, and 5 denotes a skin covered with the wading pad 4 mounted on the wading pad fitting portion 3 of the headrest body 1.

The opening edge of the wadding pad fitting portion 3 is formed in an inwardly tapering eaves-shaped engaging portion 6, and the eaves-shaped engaging portion 6 has an inversely tapered portion 7 in which the outside of the wadding pad 4 is provided. The peripheral edge is inserted in a compressed state, whereby the wadding pad 4 is embedded and integrated in the wading pad fitting portion 3 without a step. The shape of the eaves-shaped engaging portion 6 is not limited to one having a triangular cross-section as shown in FIG. 2 but also one having a gentle R shape which is connected by an arc from the bottom surface of the recess as shown in FIG. Of course, it is possible to select any shape such as.

The above-described structure is formed on the front surface of the headrest main body 1 when the head of the seated person is supported on the front surface of the headrest main body 1 and is used in the same manner as a conventional vehicle headrest of this kind. Since the wadding pad fitting portion 3 thus formed is fitted with the wadding pad 4 which is softer than the headrest body 1, the head feels extremely good.
Since the opening edge of is formed in the eaves-shaped engaging portion 6, the outer peripheral edge of the wading pad 4 fitted and mounted in the wading-pad engaging portion 3 is engaged with the eaves-shaped engaging portion 6. It does not fall out, and there is no step at the joint between the two, which makes it very attractive. That is, the wading pad 4 is embedded and integrated in the wading pad fitting portion 3 without a step in a state where the outer peripheral edge of the wading pad 4 is compressed and inserted into the eaves-shaped engaging portion 6 of the wading pad fitting portion 3. As a result, the headrest body 1
The seam between the padding pad 4 and the wadding pad 4 does not hinder the eyes, and thus it has an excellent appearance.

Moreover, even if there is a variation in the shape of the wadding pad 4, it will be covered by the eaves-shaped engaging portion 6, so that the variation can be sufficiently absorbed, and the assembly is easy and the workability is excellent. You will be able to demonstrate. In particular, when the headrest body 1 is made of a polyolefin resin bead foam, the headrest body can be hollowed out if necessary in addition to being excellent in strength. It is possible to reduce the weight and reduce the cost as compared with the case of molding with different polyurethane foams.

In the embodiment, the headrest main body, which is separate from the seatback, is attached to the top of the seatback with the stay vertically installed. However, the headrest is mounted on the top of the seatback. The present invention can also be applied to the case where a plurality of units are provided.

[0012]

As is apparent from the above description, the present invention can prevent a step from being formed at the joint between the headrest body and the wadding pad mounted on the front surface of the headrest body, and can provide an excellent appearance. At the same time, even if there are variations in the shape of the wadding pad itself, there are various advantages such as being able to easily perform the mounting work without causing a step difference, and further being able to achieve sufficient weight reduction and cost reduction. . Therefore, the present invention is extremely useful as a vehicle headrest that eliminates the conventional problems and contributes to industrial development.
