Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an armrest with an assist grip for a vehicle, which integrally connects the armrest part whose main purpose is to rest the elbow and the assist grip part which is mainly used for opening and closing doors. This invention relates to an armrest with an assist grip. In particular, the present invention is characterized by a strong connection between the inner ends of the core material, which are separately embedded in the foam body of the armrest part and the assist grip part, which constitute the armrest with assist grip, and the fixation of this armrest to the vehicle door. This is achieved simultaneously using a single large screw, with the intention of simplifying the work and the mechanism.

(Prior art) An example of an armrest with an assist grip is a series of armrests whose main purpose is to rest the elbows, etc., and assist grips which are subjected to relatively large loads such as opening and closing vehicle doors. As found in the above publications, the foam layer and its surface are covered with a skin, or when the foam layer and this foam layer are molded using the integral skin form method, a skin layer is applied to the surface in contact with the mold. A structure is known in which the reinforcing core is formed integrally with a foam layer and a reinforcing core is embedded in the foam layer.

This reinforcing core material is mainly used for the armrest part to provide a good feel when the elbow is placed on it, and for the assist grip part, it is used mainly for the purpose of providing a good feel when the elbow is placed on it. The armrest part and the assist grip part are made of completely different materials, such as a metal core material such as a steel plate, in order to be able to withstand the loads that are applied to the armrest.
A pair of reinforcing cores may be used.

(Problem to be solved by the invention) In this way, when a pair of reinforcing core materials, which are completely different in material, are embedded in the foam according to the purpose of use of the assist grip part and the armrest part, these pair of reinforcing core materials are Prior to burying the core material, a connection assembly process using rivets or the like is required.

For armrests with assist grips, by using reinforcing core materials made of materials suitable for each part, the product becomes safe, strong, and comfortable to use. In addition, the work involved in manufacturing the armrests increases, and this becomes a major hindrance in terms of work efficiency and other aspects of armrest production.

The present invention solves as much as possible the above-mentioned problems that inevitably occur due to the use of core materials made of different materials.
The object of the present invention is to provide an armrest with an assist grip that simplifies the connecting and assembling of the core material and simplifies the components for this purpose.

(Means for solving the problem) In order to achieve this objective, the present invention has the following configuration. That is, the armrest with an assist grip according to the present invention is a vehicle armrest in which an armrest part and an assist grip part are formed in series, and the reinforcing core embedded in the foam constituting the armrest has a shape that corresponds to each shape of the armrest part and the assist grip part. The pair of core materials are made of different materials that substantially match each other, and the pair of core materials are connected by a connecting means such as fitting the inner ends of each pair of core materials with through holes formed in the inner end portions thereof. The through holes are overlapped and screwed to the door using the matched through holes.

(Example) Next, a specific example of the armrest with assist grip according to the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of an armrest with an assist grip according to the present invention. A reinforcing core body 6 is embedded within the polyurethane foam 5.

This reinforcing core body 6 includes a synthetic resin core material 7 that substantially matches the outer shape of the armrest portion 2 and that reinforces the armrest portion, and a metal core material 8 that reinforces the assist grip portion that substantially matches the outer shape of the assist grip portion 3. Both core members 7 and 8 are integrally assembled by connecting their inner ends together. The armrest side core material 7 is manufactured by injection molding using, for example, polypropylene, nylon, PVC, or ABS resin, while the assist grip side core material 8 is manufactured by, for example, bending molding of a steel plate.

Elongated through holes 9 and 10 are bored near the inner ends of both core members 7 and 8, and the inner ends of both core members are connected to assemble the reinforcing core body 6. Although there are various types of connecting means, a fitting connecting means at the inner ends of both core members 7 and 8 is considered to be a desirable connecting means.

For example, as shown in FIGS. 2 and 3, a bag-shaped fitting groove 12 is formed in the flattened inner end of the armrest side core material 7, and the deepest ceiling part of this fitting groove 12 has an inward direction. A bridge 14 is spanned in the groove width direction near the front part of the fitting groove 13, and a claw 15 is provided protruding from the inner surface of the bridge 14. The long through hole 9 described above is bored at the bottom of the fitting groove so as to coincide with the longitudinal direction of the fitting groove. On the other hand, the flattened inner end 17 of the grip assist side core material 8 has an elongated hole 10 in the longitudinal direction of the core material described above, and a square hole 18 slightly behind it. (See Figures 4 and 5).

Insert the inner end 17 of the other side of the core material 8 into the bag-like fitting groove 12 of the core material 7, and then insert the inner end 17 of the inner end 17 of the core material 8
By inserting it into the deepest part of 2, the long through hole 9 of both core materials,
10 are overlapped and matched, the inward claws 15 of the bridge portion 14 of the core member 7 engage with the square holes 18 of the core member 8, and the pair of inward collars 13, 13 of the core member 7 and the bridge Due to the presence of the core members 14, wobbling and pulling out of both the core members 7 and 8 is suppressed, and the core members 7 and 8 are temporarily connected.

In addition, as another structure for this temporary connection, as shown in FIGS. 6 and 7, the armrest side core material 7
There is also a bag-shaped fitting groove 12 at the flattened inner end of the
A pair of inward band-shaped flanges 13, 13 are formed on the ceiling of the groove over the entire length of the groove, and a long through hole 9 is formed at the bottom of the groove on the back side and corresponds to the longitudinal direction of the groove. However, claws 15 protruding inward from the groove 12 are formed slightly in front of this. On the other hand, an elongated through hole 10 is formed in a portion near the tip of the flattened inner end portion 17 of the assist grip side core material 8, and a square hole 18 is formed slightly behind the elongated hole 10. In the bag-shaped fitting groove 12 of the core material 7, the fourth
Inner end 17 of the other side core material 8 shown in the figures and FIG.
When inserting into the deepest part of the groove of the inner end 17 of the core material 8, the long through holes 9 and 10 of both core materials overlap and match, and the claw 15 at the bottom of the fitting groove is inserted into the square hole. 18,
In addition, due to the existence of the pair of band-shaped inward flanges 13, 13, wobbling and pulling out of both the core members 7, 8 is suppressed, and the core members 7, 8 are temporarily connected.

Note that by tightly fitting the width of the flat part formed at the inner end of the other side core material that is fitted into the bag-shaped fitting groove into the bag-like fitting groove, the pawl 15 can be engaged with this. The square hole 18 can also be omitted.

A pair of core materials 7 and 8 made of different materials constituting the reinforcing core body 6 are connected and assembled prior to embedding in the foam 5, but at that time, each length of the pair of core materials 7 and 8 is It is important that the through holes 9 and 10 are overlapped and matched in advance.

The surface of the connected reinforcing core body 6 is covered with a single or composite skin 4 made of PVC resin (polyvinyl chloride), ABS resin, PVC resin and foamed PVC, ABS resin and foamed PP resin, etc. Or, during foam molding using the integral skin foam construction method, it is embedded in a polyurethane foam 5 that has a skin on the surface side that is simultaneously formed integrally with the foam in contact with the mold side. In order to do this, a deep hole 20 is formed in the skin 4 and the foam 5 at a position relative to the long through holes 9 and 10 that are weighted and matched at the inner end connecting portion of the pair of core materials, and from the deep hole 20. The inserted large screw 21 is firmly fixed to the door core material 22 of the vehicle through the long through holes 9 and 10 via the sleeve-shaped receiving seat 23 embedded in the door core material in advance.

As can be seen from the fixing work using this large screw 21, by making the through holes drilled in the pair of core materials long, there will be some misalignment when the two core materials are temporarily connected. Even when this occurs, it can be avoided that the tightening work using the large screw 21 is greatly hindered.

The armrest with assist grip can be secured to the door with screws at any other suitable location.

(Effects of the invention) This invention uses completely different core materials depending on the feel and purpose of use for each part of the assist grip part and the armrest part that make up the armrest with assist grip. Each core material to be implanted within the body must be assembled by connecting its two ends prior to implantation.

In the present invention, a pair of overlapping core materials is formed by pre-drilling through holes in the inner ends of each pair of core materials, and by overlapping these inner ends to make an appropriate temporary connection. By using a large screw in the through hole to secure the armrest to the vehicle door, the final and strong connection of the pair of core members is simultaneously performed, allowing for the connection and assembly of the pair of core members. , bolts and nuts that were previously considered essential parts,
There is no need for any connecting materials such as rivets, which reduces the number of parts and reduces product costs.Furthermore, when producing armrests with assist grips, the work of connecting a pair of core materials is simplified. This greatly improves work efficiency and greatly contributes to mass production.
