本発明は、グローブボックスやコンソールボックス等の
自動車内装品の蓋体及びその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a lid for an automobile interior such as a glove box or a console box, and a method for manufacturing the same.
近年、自動車用部品は極力軽量化する傾向にあるので、
これらの傾向に起因して、グローブボックスやコンソー
ルボックス等の自動車内装品の蓋体に対しても軽量化の
要請が課せられている。そこで、自動車内装品の蓋体も
、従前の表皮と金属インサートを発泡体より成るクツシ
ョン層で一体化した後この金属インサートに裏板をボル
トで固着するものに代えて、表皮と裏板とを発泡体より
成るクツシコン層で直接一体化して金属インサートを省
略する蓋体が多用されるに至った。In recent years, there has been a trend toward reducing the weight of automobile parts as much as possible.
Due to these trends, demands are also placed on the lids of automobile interior parts, such as glove boxes and console boxes, to be lighter. Therefore, instead of the conventional method of integrating the outer skin and metal insert with a cushion layer made of foam and then fixing the back plate to the metal insert with bolts, the cover body of automobile interior parts is now made of the outer skin and the back plate. Lids that are directly integrated with a cover layer made of foam and omit a metal insert have come into widespread use.
かかる表皮と裏板とを発泡体より成るクツシコン層で直
接一体化する蓋板の場合、表皮と裏板の接合部からの発
泡体の露出を防止して外観の見栄えを良くする必要があ
る（従前の金属インサートを用いるものでは、裏板で発
泡体の露出部を覆っていた）。In the case of a lid plate in which the outer skin and back plate are directly integrated with a cover layer made of foam, it is necessary to prevent the foam from being exposed from the joint between the outer skin and the back plate to improve the appearance. In previous versions using metal inserts, a backing plate covered the exposed portion of the foam).
このような発泡体の露出を防止する蓋体の一つとして、
第４図に示す、下金型ａに蓋体すの内方に向かう折り曲
げ部Ｃ＠をする表皮ｄを取付け、上金型ｅに取付けられ

泡体の露出を防止するものが提案されている（実公昭６
２−２５９５８号公報又は実開昭５８−１１１６４９号
公報参照）。As one of the lids that prevent the exposure of such foam,
As shown in FIG. 4, a skin d forming an inwardly bent portion C@ of the lid body is attached to the lower mold a, and the outer circumferential portion g of the back plate f attached to the upper mold e and the bent portion C are attached to the lower mold a. It has been proposed that the outer circumferential part g and the bent part C are joined to prevent the foam from being exposed by arranging them in opposition to each other.
(See Japanese Utility Model Publication No. 2-25958 or Japanese Utility Model Application Publication No. 58-111649).
ところが、上記提案の従来の技術によれば、第５図に示
すように、発泡体りの発泡前には、可撓性を存する表皮
ｄの折り曲げ部Ｃが自重で撓み、裏板ｆの外周部ｇとの
間に隙間αが生じていた。However, according to the conventional technique proposed above, as shown in FIG. 5, before the foam is foamed, the bent portion C of the flexible skin d bends under its own weight, causing the outer periphery of the backing plate f to bend. A gap α was created between the part g and the part g.
発泡体りが矢印Ｘのように下から沸き上がる場合は、こ
の発泡体りが折り曲げ部Ｃを押し上げて裏板ｒの外周部
ｇに接合させるが、発泡体りが矢印Ｙの方向から沸き上
がる場合には、発泡体りは隙間αから上下金型ａ、ｅ間
に漏れ出すこという問題点を有していた。このように、
発泡体が漏れ出すと、発泡体の露出によって外観の見栄
えが悪くなる他、発泡体の不足によるボイドや荒れ等の
発泡の不良率が高（なったり、上下金型間に発泡体の離
型剤を塗布する等の前作業が必要になってくる。そこで
、第６図に示すように、裏板ｆの外周部ｇを下方に突出
させ、表皮ｄの折り曲げ部Ｃに当接させようとすると、
表皮ｄは下金型ａから剥離して極端な場合には２点鎖線
のように脱落するという問題点を有していた。When the foam rises from below as shown by arrow had the problem that the foam leaked from the gap α between the upper and lower molds a and e. in this way,
If the foam leaks out, the appearance of the foam will deteriorate due to exposure of the foam, and there will be a high rate of foam defects such as voids and roughness due to insufficient foam, and the foam will be released between the upper and lower molds. Therefore, as shown in Fig. 6, an attempt was made to make the outer peripheral part g of the back plate f protrude downward and bring it into contact with the folded part C of the outer skin d. Then,
The skin d had the problem of peeling off from the lower mold a and, in extreme cases, falling off as shown by the two-dot chain line.
