Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an armrest provided on an inner surface of an automobile door, and more particularly to improvement of a core material structure thereof.

(Prior Art) As shown in FIG. 1, an armrest R on which an occupant can rest his or her elbow is projected on a door trim (lining) T attached to the inner surface of a door of an automobile. Further, in particular, the armrest R, which is particularly attached to a high-class vehicle type, has an armrest portion 1 for mounting an elbow on a rear portion thereof and a switch panel portion 2 having a power window operating switch or the like formed on a front portion thereof. It is often used that a grip portion 3 is integrally provided between the switch 1 and the switch panel portion 2 so that an occupant can easily grip the door when opening and closing the door. Due to these functions, the armrest portion 1 and the switch panel portion 2 have a wide width dimension, and the grip portion 3 has a narrow width dimension.

Such an armrest R is formed by covering an insert, which is a core material, with a skin made of, for example, PVC (vinyl chloride) material, and filling a foam elastic material, for example, urethane foam material between the skin and the insert. It is a thing.

FIG. 5 shows the shape structure of the insert 4 which is the core material of the armrest R used conventionally. The wide part on the right side of the figure is the armrest part 1, the wide part on the left side is the switch panel part 2, and the narrow part between them is the grip part 3, all of which are integrally formed. Become. The switch panel section 2 is provided with an opening 5 for mounting the switch panel.

FIG. 6 shows a shape of the armrest R, and particularly shows the grip portion 3 in a vertical section. Insert 4 above
Is covered with a skin 6, and a urethane foam material 7 is filled between the skin 6 and the insert 4.

(Problems to be Solved by the Invention) By the way, the outer skin 6 is a bag having a wide width dimension at both ends and a narrow central width dimension, similar to the shape of the insert 4. Skin 6 for armrest molding
When the insert 4 is wrapped from the opening side of the one end, the central thin portion of the skin 6 catches on the end of the insert 4 and cannot be inserted any further. Therefore, as also shown in FIG. 6, the outer skin 6 is provided with a cut portion 8 cut along the axial direction of only the portion enclosing the grip portion 3. Then, when the insert 4 is encapsulated, the cut portion 8 is opened and the wide end portion is passed. After completely encapsulating, the cut portion 8 is closed, set in a urethane injection mold (not shown), and the urethane foam material 7 is injected and foamed. The cut portion 8 is located inside the armrest R so as not to be seen by an occupant, that is, it does not spoil the appearance.

However, it is inevitable that the cut portion 8 touches the hand, especially when an occupant grips the grip portion 3, and thus the feel is bad. Also, the epidermis 6 may peel off from the cut portion 8 over a long-term use.

If the skin 6 is not cut, the above problems will not occur. Therefore, as shown in FIG. 7, for example, the switch panel portion 2 is the same as before, but the armrest portion 1a
It is conceivable to form an insert 4a having the same width as the grip portion 3. Here, the skin (not shown) can encapsulate the insert 4a without providing the above-described cut portion. When a urethane foam material is filled between the skin and the insert 4a, the product shape as the armrest is the same as that shown in FIG.

However, on the other hand, in particular, the width of the insert 4a of the armrest portion 1a becomes narrower, and the portion shown by the chain double-dashed line in the figure only covers the urethane foam material with the skin. That is, since there is no insert in this portion, the rigidity is impaired, and the elbow of the occupant cannot be reliably supported.

Further, as shown in FIG. 8, the switch panel portion 2 in which the insert is covered with the skin through the foamed elastic material is used as one part,
There is also a structure in which the grip 3 and the armrest 2 in which the insert is covered with a skin through a foamed elastic material are used as one part, and the armrest Ra is configured by connecting and fixing each other by some connecting means.

With such an armrest Ra, it is apparent that the armrest Ra is divided, and the aesthetic appearance is impaired, and particularly, the rigidity of the grip portion 3 is reduced.

The present invention has been made in view of the above circumstances, and by dividing the core material, the core material can be wrapped with an uncut skin, and the feel when gripping the grip part is impaired. It is an object of the present invention to provide an armrest capable of increasing the strength of the armrest.

[Constitution of device]

(Means for Solving the Problems) That is, according to the present invention, a core material is covered with a skin, and a foamed elastic material is filled between the skin and the core material. Is an armrest in which a narrow portion having a narrow width is integrally provided between the front portion and the rear portion, and the core member is provided on the front portion side and the rear portion side with the narrow portion as a boundary.
In addition to dividing, one protrusion is provided with a protrusion and the other divider is provided with a hole in the front-rear direction, and the protrusion and the hole are fitted to integrate the core material. It is an armrest.

(Operation) Since each of the splitting pieces of the core material is inserted from both ends of the skin and the splitting elements are fitted to each other to integrate the core material, the cut piece is not necessary for this skin. There is no problem in filling the foamed elastic material. Moreover, the grip portion of the core material has a double structure.

(Embodiment) Hereinafter, one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the outer shape of the armrest R attached to the door trim T has no change. And a new description is omitted. 2 and 3
As shown in the figure, the insert 10 which is a core material is composed of two split members 10a and 10b. These dividers 10a and 10b are formed by dividing the grip portion 3 which is a narrow width portion into front and rear portions. Therefore, one of the dividers 10a includes a part of the grip portion 3 and the armrest portion 1 which is a rear portion,
The other divider 10b includes a part of the grip portion 3 and the switch panel portion 2 which is the front portion. Further, a projection 11 having a cross-sectional area slightly smaller than the cross-sectional area of this end surface is integrally provided on the end surface of the divider 10a on the armrest 1 side. A hole 12 having a sectional shape into which the protrusion 11 can be fitted is opened at an end surface of the divider 10b on the switch panel 2 side. That is, the protrusion 11 and the hole 12 are oriented in the front-rear direction.

Then, when molding the armrest R, the splitting elements 10a and 10b of the insert 10 divided into two are inserted from both side ends of the not-shown skin. In addition, if it explains, it will be inserted in the epidermis from the grip parts 3 and 3 side with a narrow width of each divider 10a and 10b. And one split 10
The protrusion 11 of a is inserted into the hole 12 of the other splitting member 10b, and the splitting members 10a and 10b are connected by inserting and fitting until the end faces of the splitting members are joined,
An insert 10 is obtained which is integrated and encapsulated with a skin. That is, the insert 10 is divided into a switch panel portion 2 which is a front portion and an armrest portion 1 which is a rear portion with a grip portion 3 which is a narrow portion as a boundary. It is integrated by the combination. This is set in a urethane injection type not shown.

As shown in FIG. 4, a urethane foam material 14 which is a foaming elastic material is injected and foamed between the insert 10 and the outer skin 13 to obtain an armrest R. In particular, in the grip portion 3, the protrusions 11 of the dividers 10a and 10b and the holes 12 are fitted to each other to form a double structure, and thus the section modulus becomes large and the rigidity is increased. Moreover, since the outer skin 13 has no cut and the entire circumference is integrated, the feel of gripping the grip portion 3 is not impaired, and
There is no partial peeling of the epidermis 13.

[Effect of device]

As described above, according to the present invention, by dividing the core material into two parts on the front and rear sides with the narrow portion as a boundary, the skin can be wrapped without cutting and the grip portion that is the narrow portion can be gripped. The feeling when touched is not impaired and partial peeling of the epidermis can be prevented.

Further, in the grip portion, the projection and the hole are fitted to each other to have a double structure, so that the section modulus is increased and the rigidity is increased, and the engagement direction between the projection and the hole is set in the front-rear direction. This direction is perpendicular to the direction in which the armrest is pulled to close the door, and there is no risk of disengagement between the protrusion and the hole, and there is no need for reinforcement, and the reliability can be improved. .
