자동차용 도어 인사이드 벨트 웨더 스트립 {DOOR INSIDE BELT WEATHER STRIP FOR AUTOMOBILE}Door inside belt weather strip for car {DOOR INSIDE BELT WEATHER STRIP FOR AUTOMOBILE}

본 발명은 자동차용 도어 인사이드 벨트 웨더 스트립에 관한 것이다.The present invention relates to a door inside belt weather strip for automobiles.

자동차의 도어 글래스는 도어 인너 패널과 도어 아웃터 패널 사이에 형성되는 공동에 승강할 수 있게 설치하는 것임으로 도어 트림과 도어 아웃터 패널의 상단에 각각 도어 인사이드 벨트 웨더 스트립과 도어 아웃사이드 벨트 웨더 스트립을 설치하여 소음, 빗물 등의 실내 유입을 방지하고 있다.The door glass of the car is installed in the cavity formed between the door inner panel and the door outer panel so that the door inside belt weather strip and the door outside belt weather strip are installed on the top of the door trim and the door outer panel, respectively. This prevents the inflow of noise and rainwater into the room.

종래의 도어 인사이드 벨트 웨더 스트립은 도 4 및 도 5에 도시한 바와 같이 웨더 스트립 본체(20)는 경질 합성수지제 고정부(21)와 연질 합성수지제 밀폐립(22)을 공압출하여 형성함과 동시에 고정부(21)의 내부에 스테인레스 박판 등의 금속제 보강심(23)을 인써트하여 압출성형하고, 상기 보강심(23)을 타발성형하여 보강심(23)과 직각으로 수개의 고정편(24)을 형성한 것이다.In the conventional door inside belt weather strip, as shown in FIGS. 4 and 5, the weather strip main body 20 is formed by co-extruding the hard synthetic resin fixing part 21 and the soft synthetic resin sealing lip 22. Inserting and reinforcing the reinforcing core 23 made of metal such as a stainless steel sheet into the inside of the fixing portion 21 by extrusion molding, and the plurality of fixing pieces 24 at right angles to the reinforcing core 23. It is formed.

한편 도어 트림(25)에는 상단에 수개의 지지편(26)을 설치함과 동시에 상기 지지편(26)에 상기 고정편(24)과 동일 간격의 지지공(27)을 형성하여서, 상기 고정부(21)를 도어 트림(25)의 상단 및 지지편(26)에 지지시키면서 고정편(24)을 지지공(27)에 삽입한 후 고정편(24)을 구부려서 웨더 스트립 본체(20)를 도어 트림(25)에 조립 설치한 것이다.On the other hand, the door trim 25 is provided with a plurality of support pieces 26 on the top and at the same time to form a support hole 27 at the same interval as the fixing piece 24 in the support piece 26, the fixing portion Inserting the fixing piece 24 into the support hole 27 while supporting the upper side of the door trim 25 and the supporting piece 26, and bending the fixing piece 24 to open the weather strip main body 20 by the door. It is assembled to the trim 25.

미설명부호 28은 도어 글래스이고, 29는 도어 아웃터 패널이며, 30은 도어 인너 패널이다.Reference numeral 28 is a door glass, 29 is a door outer panel, and 30 is a door inner panel.

그러나 상기한 도어 인사이드 벨트 웨더 스트립은 아래와 같은 문제점이 발생하고 있다.However, the door inside belt weather strip has the following problems.

첫째, 웨더 스트립 본체(20)는 스테인레스 박판을 롤 성형한 보강심(23)을 인써트하여 압출성형한 후 고정편(24)을 타발성형하여야 함으로 재료비가 고가로 되고, 성형 및 타발공정이 복잡하여 원가가 상승된다.First, the weather strip body 20 inserts the reinforcing core 23 roll-formed from a stainless steel sheet and then extrudes and then molds the fixing piece 24 so that the material cost becomes expensive, and the molding and punching process is complicated. The cost rises.

둘째, 보강심(23)에 형성한 고정편(24)을 지지편(26)에 형성한 지지공(27)에 삽입한 후 고정편(24)을 구부려야 함으로 웨더 스트립 본체(20)의 조립공정이 복잡하다.Second, assembling the weather strip body 20 by inserting the fixing piece 24 formed in the reinforcing core 23 into the support hole 27 formed in the supporting piece 26 and then bending the fixing piece 24. The process is complicated.

셋째, 웨더 스트립 본체(20)의 보강심(23)에 형성한 고정편(24)을 지지편(26)에 형성한 지지공(27)에 삽입 조립할 때 조립공차 등이 발생하기 때문에 이를 극복하기 위하여 지지공(27)의 단면적을 크게 형성하여야 함으로써, 웨더 스트립 본체(20)를 조립한 후 상하 및 도어와 직각방향으로 유동하여 소음 등의 차단기능이 떨어지고, 웨더 스트립 본체(20)가 상하 및 도어와 직각방향으로 유동하면 도어 글래스(28)의 승강시에 밀폐립(22)이 도어 글래스에서 들뜨거나 끼임이 발생함으로 소음 차단기능이 떨어질 뿐아니라 소음이 발생하며 밀폐립(22)과 도어 글래스(28)의 마찰이 커짐으로 작동감이 떨어지고 도어 글래스 승강수단 등의 고장을 일으킨다.Third, when the fixing piece 24 formed on the reinforcing core 23 of the weather strip body 20 is inserted into the support hole 27 formed on the support piece 26, an assembly tolerance or the like occurs to overcome this problem. In order to form a large cross-sectional area of the support hole 27, the weather strip main body 20 is assembled and then flows up and down and at a right angle with the door, so that a blocking function such as noise is reduced, and the weather strip main body 20 is moved up and down and Flowing in the direction perpendicular to the door, the sealing lip 22 is lifted or pinched in the door glass during the lifting of the door glass 28, so that the noise blocking function is lowered and noise is generated, and the sealing lip 22 and the door glass are made. As the friction of (28) increases, a feeling of operation decreases and a failure of door glass lifting means or the like occurs.

본 발명은 상기한 문제점을 시정하여, 원가를 절감하고, 조립공정을 단순화하며, 밀폐성능을 양호하게 한 자동차용 도어 인사이드 벨트 웨더 스트립을 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention aims to provide a door inside belt weather strip for automobiles, which has corrected the above problems, reduces costs, simplifies the assembly process, and improves sealing performance.

상기한 목적을 달성하기 위하여, 본 발명은 웨더 스트립 본체의 고정부와 밀폐립을 공압출 형성함과 동시에 고정부에 제 1 및 제 2 지지홈을 형성하고, 도어 트림의 상단 내부에 지지판을 형성하여서, 상기 제 1 지지홈을 지지판에, 제 2 지지홈을 도어 인너 패널의 상단에 형성한 플랜지에 삽입 고정한 것이다.In order to achieve the above object, the present invention forms the first and second support grooves in the fixing portion and co-extrudes the fixing portion and the sealing lip of the weather strip body, and forms a supporting plate inside the upper end of the door trim. Thus, the first support groove is inserted into the support plate and the second support groove is inserted into the flange formed on the upper end of the door inner panel.
