Description

헤드레스트의 제조방법{A MANUFACTURING METHOD OF HEAD REST}Manufacturing method of headrest {A MANUFACTURING METHOD OF HEAD REST}

본 발명은 자동차용 시트의 헤드레스트, 상세하게는 주머니모양으로 봉제한 표피내에 패드를 일체로 발포하여 형성하는 헤드레스트의 제조방법에 관한 것이다.The present invention relates to a headrest of an automobile seat, and more particularly, to a method of manufacturing a headrest formed by integrally foaming a pad in a skin enveloped in a bag shape.

종래의 헤드레스트에는 주머니모양으로 봉제한 표피의 개구부로부터 내부로 U자형상으로 절곡된 스테이를 장착한 후 표피내에 발포액을 주입하여 패드를 표피와 일체로 성형하여 이루어진 것이 있다.The conventional headrest is formed by mounting a stay bent in a U-shape from the opening of the epidermis sewn into a bag shape, and then injecting a foam liquid into the epidermis to form the pad integrally with the epidermis.

이는 표피의 개구부로부터의 발포액이 외부로 누출되는 것을 방지하기 위해 개구부에서 주머니모양의 안쪽에 표피의 단부를 연설하여 이루어지는 한쌍의 설편(舌片)을 마련하고, 이 설편사이에 통형상필름을 끼워넣어 이 통형상필름내에 패드발포용의 발포액 주입용 주입노즐을 꽂아 패드를 표피와 일체로 발포성형하고 있다(예를들어 일본국 특공평 6-45149호 공보, 일본국 특개평 7-31759호 공보).또한 주머니 모양으로 봉제한 표피의 개구부에서 내부를 향해 좌우 양측에 짧은 설편과 긴 설편을 연설하고, 긴 설편의 기단측에 주입공을 뚫어 주입공을 통하여 주입노즐을 꽂은후 발포액을 주입시켜 긴 설편의 기단측이 짧은 설편을 감싸서 개구부를 막게 한 것이 있다(미국특허 제5,855,831호 공보).This provides a pair of tongues made by spreading the ends of the epidermis inside the pouch shape at the openings to prevent leakage of the foam liquid from the epidermis openings, and between the tongues a cylindrical film is formed. The pad is inserted into the tubular film by injecting an injection nozzle for injecting the foam liquid into the tubular film and foaming the pad integrally with the skin (for example, Japanese Patent Application Laid-Open No. 6-45149, Japanese Patent Laid-Open No. 7-31759). In addition, the short tongue and long tongue are spoken from both sides to the inside from the opening of the pouch-sewn epidermis, and the injection nozzle is inserted through the injection hole at the proximal end of the long tongue, and then the foam liquid is discharged. By inserting the proximal end of the long tongue, the short tongue is wrapped to block the opening (US Patent No. 5,855,831).

따라서 종래방법에 의하면 패드를 발포성형후 통형상 필름을 표피로부터 절리할 필요가 있어 그 작업성이 좋지 않고, 절리시 표피를 손상시킬 염려도 있다. 또는 긴 설편이 짧은 설편을 확실하게 밀착하여 감싸지 못하므로 발포액이 개구부로 누출될 염려가 있다.그래서 본 발명은 그와같은 종래방법에 의한 문제를 제거하는 것을 목적으로 한다.Therefore, according to the conventional method, it is necessary to cut the tubular film from the epidermis after foaming the pad, and its workability is not good, and there is a fear of damaging the epidermis during cutting. Alternatively, the long tongue may not wrap tightly against the short tongue, so that the foam liquid may leak into the opening. Therefore, the present invention aims to eliminate the problem caused by such a conventional method.

이상의 목적을 이루기 위한 본 발명에 관한 헤드레스트의 제조방법은 주머니모양으로 봉제한 표피에 패드성형용의 발포액을 주입함으로써 패드를 표피와 일체발포성형하여 이루어지는 헤드레스트에 있어서, 상기 발포액 주입용 주입노즐의 표피내로 꽂혀지는 부분에 걸림돌기를 마련하고, 주입노즐을 표피내에 꽂은 후 꽂아넣은 방향에 대해 반대방향으로 차단함으로써 걸림돌기에 의해 표피에 마련한 스테이삽입용의 개구부를 개구부에서 내측에 마련한 긴 설편으로 막아 개구부로부터의 발포액이 누출되는 것을 방지하는 것을 특징으로 하는 것이다.The headrest manufacturing method according to the present invention for achieving the above object is in the headrest formed by integrally foaming the pad with the epidermis by injecting the foam for pad molding into the epidermis sewn in the shape of a bag, the foam liquid for injection Long tongues provided with an opening for stay inserts provided on the epidermis by openings in the epidermis by interlocking the injection nozzle into the epidermis of the injection nozzle and blocking the injection nozzle in the opposite direction to the inserted direction. This prevents the foaming liquid from the opening from leaking out.

이상의 구성에 의해 표피에 개구부를 막는 폐구부재를 마련할 필요가 없다.By the above structure, it is not necessary to provide the closure member which closes an opening part in an epidermis.

또 상기 표피에서 스테이삽입용 개구부의 좌우양단테두리에 긴 설편, 짧은 설편을 연설하고, 한쪽 긴 설편은 다른쪽 짧은 설편에 대해 표피의 내부방향으로의 전체 길이를 길게 형성하며, 긴 설편에서 짧은 설편의 선단테두리에 대응하는 곳에 상기 주입노즐의 주입공을 뚫고 상기 주입노즐의 표피내로 꽂히는 부분외주에는 걸림돌기를 마련하여 주입노즐을 꽂아넣은 방향과 반대방향으로 당겨서 차단하는 것에 의해 걸림돌기로 긴 설편을 짧은 설편의 선단부에 접합시킨 후 주입노즐에서 표피내로 발포액을 주입함으로써 긴 설편이 발포액의 발포압력에 의해 짧은 설편을 감아 개구부를 완전히 막을 수 있다.In addition, the epidermis speaks long tongues and short tongues on the left and right edges of the stay insertion opening, and one long tongue forms the entire length of the epidermis in the inner direction with respect to the other short tongue. The long tongue is shortened by the locking projection by cutting the injection hole of the injection nozzle at a portion corresponding to the front edge of the injection hole, and providing a locking projection at the outer circumference of the injection nozzle to pull it in the direction opposite to the direction in which the injection nozzle is inserted. By adhering the foam liquid into the epidermis from the injection nozzle after joining to the tip of the tongue, the long tongue can wind up the short tongue by the foaming pressure of the foam and completely block the opening.

본 발명의 실시의 일예를 도면을 기초로 설명한다.An embodiment of the present invention will be described based on the drawings.

도 1은 본 발명에 의해 패드발포성형용 발포액을 주입노즐(1)에서 주머니모양으로 봉제한 표피(C)내로 주입하는 상태를 나타낸다.1 shows a state of injecting the foam for foam pad molding according to the present invention into the cuticle (C) sewn in a bag shape in the injection nozzle (1).

표피(C)를 구성하는 바닥천(3)(4)사이에 개구부(A)를 갖고, 이 개구부(A)에서 U자형상으로 절곡된 스테이(S)를 장착하여 바닥천(4)에 구멍을 뚫은 통기공에서 스테이(S)의 다리부를 외부로 돌출하고 있다.An opening A is provided between the bottom fabrics 3 and 4 constituting the skin C, and a stay S bent in a U shape is mounted in the opening A to form a hole in the bottom fabric 4. In the vent hole through the protruding leg portion of the stay (S) to the outside.

표피(C)는 직물지, 기모천(起毛布) 등의 표피재와, 이 표피재의 뒷면에 일체로 고정하여 장착한 우레탄폼의 슬러브재로 이루어지는 와딩과, 이 와딩외면에 일체로 갖는 와딩커버 및 와딩으로 이루어지는 적층체로 구성된다.The outer skin (C) is a covering made of a skin material such as woven paper, a brushed cloth, a urethane foam slab material which is fixedly attached to the back of the skin material, and a covering cover integrally formed on the outer surface of the covering; It consists of a laminated body which consists of a wading.

개구부(A)의 좌우양단테두리에는 내부방향을 향해 긴 설편(40), 짧은 설편 (30)이 연설되고, 긴 설편(40)은 짧은 설편(30)에 대해 내부방향으로 길게 형성되며, 짧은 설편(30)에 대해 길다란 선부를 돌편(41)으로 한다.Long tongue 40, short tongue 30 are spoken in the right and left edges of the opening A, and the long tongue 40 is formed long inward with respect to the short tongue 30, and the short tongue The long line with respect to (30) is used as the protrusion piece 41.

이 돌편(41)의 기단측에는 상기 주입노즐(1)의 주입공(41A)이 뚫려지고, 이 주입공(41A)에서 주입노즐(1)이 표피(C)내로 꽂히게 된다.The injection hole 41A of the injection nozzle 1 is drilled in the proximal end of the protrusion piece 41, and the injection nozzle 1 is inserted into the skin C in the injection hole 41A.

표피(C)내로 꽂아넣은 주입노즐(1)을 꽂아넣은 방향과 반대방향으로 당기는 것에 의해 주입노즐(1)의 꽂힌 부분 외주에 있는 걸림돌기(2)가 돌편(41)의 기단측을 짧은 설편(30)의 선단부에 접합하도록 구성된다.By pulling the injection nozzle 1 inserted into the skin C in the direction opposite to the insertion direction, the engaging projection 2 on the outer circumference of the plugged portion of the injection nozzle 1 has a short tongue on the proximal end of the protrusion 41. It is comprised so that the tip part of 30 may be joined.

또한 도면의 부호 10은 주입노즐(1)에 마련한 깔대기모양의 주입기를 나타낸다.Reference numeral 10 in the drawings denotes a funnel-shaped injector provided in the injection nozzle 1.

도 2는 상기 주머니모양으로 봉제한 표피(C)를 나타내고, 긴 설편(40), 짧은 설편(30)은 양단이 일체로 재봉실(34)에 의해 꿰매지고, 서로 접합하여 개구부(A)가 패드발포성형용의 발포액이 누출되지 않도록 하고 있다.Fig. 2 shows the cuticle C sewn in the bag shape. The long tongue 40 and the short tongue 30 are sewn together by a sewing thread 34 at both ends thereof, and are joined to each other so that the opening A is padded. The foaming liquid for foam molding is prevented from leaking.

도 3의 A,B,C,D는 본 발명에 의한 헤드레스트의 제조방법을 나타낸다.A, B, C, and D of FIG. 3 show a method of manufacturing a headrest according to the present invention.

본 발명에서 사용하는 주입노즐(1)은 도 5와 같이 선단외주에 걸림돌기(2)를 갖는 것으로 이 걸림돌기(2) 앞쪽에 발포액의 토출부(1A)를 갖는다.The injection nozzle 1 used in the present invention has a locking projection 2 at the outer periphery of the tip as shown in FIG. 5 and has a discharge portion 1A of the foamed liquid in front of the locking projection 2.

걸림돌기(2)는 표피(C)의 주입공(41A)의 내경에 대해 대경의 외경을 갖는 것으로 표피(C)내에 꽂아넣은 주입노즐(1)이 움푹들어가는 것에 의해, 돌편(41)을 짧은 설편(30)의 선단에 접합하여 긴 설편(40)과 짧은 설편(30) 사이에 간극이 생기지 않도록 하는 것이면 도시한 것에 한정되지 않는다.The locking projection 2 has a large diameter outer diameter with respect to the inner diameter of the injection hole 41A of the skin C. As the injection nozzle 1 inserted into the skin C is recessed, the projection piece 41 is shortened. It is not limited to what was shown if it is joined to the front-end | tip of tongue tongue 30 so that a clearance gap may not arise between long tongue piece 40 and short tongue piece 30.

또한 걸림돌기(2)가 주입노즐(1)의 주입공(41A)에서 꽂아넣은 후 주입노즐(1)을 표피(C)안에서 빼낼 수 있도록 주입공(41A)을 갖는 돌편(41)은 상술한 것과 같이 와딩 등으로 이루어지는 탄성천을 사용하고 있다.Further, the protrusion piece 41 having the injection hole 41A so that the locking projection 2 is inserted into the injection hole 41A of the injection nozzle 1 and then the injection nozzle 1 can be pulled out of the epidermis C may be described above. As such, an elastic cloth made of warding or the like is used.

다음은 본 발명에 관한 헤드레스트의 제조방법을 순서대로 설명한다.Next, the manufacturing method of the headrest which concerns on this invention is demonstrated in order.

도 3의 A는 표피(C)내로 주입노즐(1)을 꽂아넣은 상태를 나타내고, 주입노즐(1)은 개구부(A)에서 주입공(41A)을 거쳐 걸림돌기(2)가 표피(C) 내부에 위치하고 있다.3A shows a state in which the injection nozzle 1 is inserted into the skin C, and the injection nozzle 1 passes through the injection hole 41A in the opening A, and the engaging protrusion 2 is in the skin C. It is located inside.

다음 주입노즐(1)을 화살표방향(윗쪽)으로 끌면 도 3의 B와 같이 돌편(41)의 기단이 걸림돌기(2)에 의해 짧은 설편(30)의 선단부에 접합하고, 돌편(41)이 수평형상으로 절곡한다. 그 때문에 짧은 설편(30)의 선단부와 긴 설편(40)사이에 간극이 없어지고 발포액(P1)이 그 간극으로 들어갈 여유가 없다. 이 상태에서 표피(C)내로 발포액(P1)을 주입한다.Next, when the injection nozzle 1 is dragged in the direction of the arrow (up), as shown in B of FIG. 3, the proximal end of the protrusion 41 is joined to the distal end of the short tongue 30 by the locking protrusion 2, and the protrusion 41 is Bend horizontally. As a result, there is no gap between the tip of the short tongue 30 and the long tongue 40, and the foaming liquid P 1 cannot afford to enter the gap. In this state, the foaming liquid P 1 is injected into the epidermis C.

그러면 표피(C)의 하부내로 주입된 발포액(P1)이 위쪽을 향해 발포하면서 이행한다. 그 때문에 이 발포액(P1)의 압력으로 도 3의 C와 같이 수평형상의 돌편(41)이 짧은 설편(30)의 내면측에 압접하여 돌편(41)과 짧은 설편(30)와의 사이에 간극이 생기지 않는다. 그리고 도 3의 D와 같이 표피(C)내부 전체에 발포하여 패드(P)가 성형된다.Then, the foaming liquid P 1 injected into the lower part of the epidermis C transfers while foaming upward. Therefore, with the pressure of the foam liquid P 1 , the horizontally shaped stone piece 41 is pressed against the inner surface side of the short tongue piece 30 as shown in Fig. 3C, and between the stone piece 41 and the short tongue piece 30. There is no gap. As shown in FIG. 3D, the entire surface of the skin C is foamed to form the pad P. FIG.

그런 후 주입노즐(1)을 걸림돌기(2)와 함께 표피(C)내로부터 빼내면 도 4와같이 개구부(A)에서 발포액(P1)이 전혀 새지 않는 헤드레스트가 성형된다.Then, when the injection nozzle 1 is pulled out from the skin C together with the locking projection 2, a headrest is formed in which the foaming liquid P 1 does not leak at all in the opening A as shown in FIG.

또한 도시하는 표피(C)는 개구부(A)에 돌편(41)이 있는 긴 설편(40)과 짧은 설편(30)을 마련하는 것에 의해 발포액(P1)의 개구부(A)로부터의 누출을 방지하고 있지만 긴 설편(40), 짧은 설편(30)을 마련하지 않고 걸림돌기(2)에 의해 개구부(A)를 막는 부재를 개구부(A)의 내부측에 마련하도록 해도 좋다.Epidermidis (C) which also shown is the leakage from the opening (A) of the foam solution (P 1) by providing the protrusion pieces 41, the long tongue piece 40 and the short tongue 30, which is in the opening (A) Although preventing, the long tongue 40 and the short tongue 30 may not be provided, but the member which blocks the opening A by the locking protrusion 2 may be provided in the inside of the opening A. FIG.

본 발명에 의하면 주입노즐에 걸림돌기를 마련하고 이 걸림돌기에 의해 주머니모양으로 봉제한 표피의 개구부를 막은 후 표피내에 패드성형용 발포액을 주입하여 패드를 발포성형하므로 표피측에 개구부를 폐구하는 폐구부재를 마련할 필요가 없다.According to the present invention, there is a closing member for closing the opening on the skin side by providing a locking protrusion on the injection nozzle and closing the opening of the skin, which is sewn into a bag shape by the locking protrusion, and then injecting a foaming solution for pad molding into the skin. There is no need to raise.

그 때문에 표피의 봉제작업이 양호하게 되고, 상기 종래품과 같은 발포액 주입후의 작업이 불필요하게 된다. 또한 걸림돌기가 표피내로부터의 탈락방지가 되어 확실하게 패드를 발포성형할 수 있다.As a result, the sewing work of the epidermis becomes satisfactory, and the work after the injection of the foaming liquid as in the prior art is unnecessary. In addition, it is possible to reliably foam the pad by preventing the protrusion from falling off from the skin.
