DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an armrest with a cup holder and a method for manufacturing the same.

[0002]

2. Description of the Related Art A seat or the like of an automobile is sometimes provided with an armrest having a foam surface covered with a skin as an armrest of an occupant. Some armrests are provided with a cup holder on an upper surface for holding a cup or canned beverage upright. For example, an armrest with a cup holder may be used as a rear center armrest rotatably attached to a center portion of a rear seat of an automobile. In this case, the armrest with the cup holder is stored so as to be raised to the backrest side when not in use to constitute a part of the backrest portion, and is taken out so as to be tilted forward during use and positioned on the seat. Is done. Then, a cup, a canned beverage, or the like is inserted upright into a cup holder provided on the upper surface of the armrest taken out, and is held so as not to fall down due to the vibration of the automobile.

Conventional armrests with cup holders are:
A substantially rectangular foam was housed in the bag-like skin together with the core material inside, and a cup holder was inserted through an opening formed by a slit (cut) formed in the skin and fixed to the core material with screws or the like. Structures are common. The core material is for increasing the strength of the armrest and for rotatably attaching the armrest to the seat back.

[0004] However, the conventional armrest with a cup holder is a foam obtained by foaming into a substantially rectangular shape with a core material previously built therein, and then pressed into a bag-shaped skin, and the skin and the foam are bonded to each other. Therefore, there is a problem that the skin is displaced from the surface of the foam at the time of use to cause wrinkles, thereby impairing the appearance and feeling of use.

[0005] In addition, in order to minimize the slack of the skin, the foam is molded somewhat larger than the bag-like skin, and is pressed into the skin in a compressed state. Because the inner surface of the skin is in close contact with the skin, the foam is crushed at the corners of the armrest and the corners are loosened, and the corners are loose. There is also a restriction that it must be done. Furthermore, the bag-shaped skin needs an opening for inserting the foam, and the opening needs to be provided with a fastener for closing after the foam is stored, which not only causes an increase in cost but also increases the cost. There is also a problem that the appearance is easily damaged.

Further, in the core material, a recess for the cup holder is formed in the foam when molding the foam, the tip of the armrest gripped when the armrest is stored and taken out is strengthened, and the cup holder is screwed with a screw or the like. In order to be able to be fixed by the above, a cup-shaped concave portion is provided in which the entire bottom surface and the entire side surface are surrounded by a wall surface. For this reason, the weight of the core material increases and the weight of the entire armrest increases,
There is a problem that costs are increasing.

In the operation of manufacturing the armrest with a cup holder, the foam after foam molding is forcibly pushed into the bag-like skin, or the periphery of the cup holder insertion opening of the skin is bent inward to form a core material. To the nails of
Work such as assembling the cup holder in a later process is necessary, and when pushing the foam into the bag-like skin, the work must be performed with care so as not to loosen or wrinkle the skin. However, there is a problem that it is complicated and requires skill.
