Abstract

에어백 커버(13)는 내층(14)과 외층(19)으로 구성된 가소성 재질의 적층판이다. 내층에는 채널로 구성된 물리적 취약선(또는 분할선)(17)이 있다. 외층에는 (외층의) 다른 부분보다 더 얇은 두께로 된 부분인 또다른 분할선(20)이 있다. 이 두 분할선은 최소 2밀리미터 정도 분지되어 (off-set)있으며 따라서 이 선들의 위치를 커버 밖에서는 발견할 수 없다. 에어백(10)이 팽창하면, 커버 일부(공동)(18)가 문처럼 열리고 내층 및 외층이 분할선을 따라 갈라진다.

Description

에어백 조립체(AN AIR-BAG ARRANGEMENT)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 전형적인 현재의 에어백 커버의 단면도,
제2도는 눈으로 식별할 수 있도록 오목하게 눌린"스타일 라인"(5)을 커버 외층(3)의 표면에 표시한 것을 보여준다.
제3도는 본 발명의 커버를 포함한 에어백 조립체의 단면도,
제4도는 제3도의 선 A-A을 절단한 단면도.

Claims (15)

  1. 고분자 재질의 내층과 외층으로 구성된 적층판으로서 각 층에는 물리적 취약선(또는 분할선)이 있으며 외층의 분할선은 내층이 분할선으로부터 2밀리미터 이상 떨어져 있고, 이 두 분할선은 함께 내부로부터 예정 압력이 가해질 때면 열리는 "문"을 형성하며 또한 각 층의 분할선이 얇은 두께의 선을 구성하는 것을 특징으로 하는 에어백용 커버.
  2. 제1항에 있어서, 내층은 딱딱하고 단단한 재질로 되어있고 외층은 연성 재질로 구성된 것을 특징으로 하는 커버.
  3. 제1항 또는 제2항에 있어서, 양쪽층은 열가소성 탄성중합체로 구성된 것을 특징으로 하는 커버.
  4. 전술한 항 중 어느 항에 있어서, 각 층의 두께는 1.5 내지 3밀리미터인 것을 특징으로 하는 에어백용 커버.
  5. 전술한 항 중 어느 한 항에 있어서, 외층의 분할선 부분에는 내층에 외층속으로 올라간 돌출부 또는 리지(ridge)가 있어서 리지 윗부분이 외층의 다른 부분 보다 그 두께가 더 얇지만 그럼에도 불구하고 외층 표면을 편평한 상태로 유지할 수 있는 것을 특징으로 하는 에어백용 커버.
  6. 전술할 항 중 어느 한 항에 있어서, 분할선 부분의 외층 두께는 0.5 내지 1밀리미터인 것을 특징으로 하는 커버.
  7. 전술한 항 중 어느 한 항에 있어서, 내층의 분할선은 얇은 두께의 선으로 된 연장 채널을 포함하고 채널 바닥을 관통하는 다수의 공동이 있고 이 공동이 내층의 끝까지 연장되어 있는 것을 특징으로 하는 커버.
  8. 제7항에 있어서, 공동이 연장형(elongate form)인 것을 특징으로 하는 커버.
  9. 제7항 또는 제8항에 있어서, 공동의 폭이 0.5 내지 1밀리미터이고 길이가 3 내지 10밀리미터인 것을 특징으로 하는 커버.
  10. 제7항 내지 제9항에 있어서, 각 공동의 길이가 약 5 밀리미터인 것을 특징으로 하는 커버.
  11. 제7항 내지 제10항에 있어서, 공동의 사잇간격이 일정하며 이 간격이 공동의 길이와 사실상 동일한 것을 특징으로 하는 커버.
  12. 전술한 항 중 어느 항에 있어서, 내부 커버에서 분할선이 있는 부분의 두께가 0.5 내지 1밀리미터인 것을 특징으로 하는 커버.
  13. 전술한 항 중 어느 항에 있어서, 내층의 분할선은 외층의 분할선으로부터 2 내지 10밀리미터가 분지(off-set)된 것을 특징으로 하는 커버.
  14. 제13항에 있어서, 내층의 분할선은 외층의 분할선으로부터 4 내지 6밀리미터가 분지(off-set)된 것을 특징으로 하는 커버.
  15. 제14항에 있어서, 내층의 분할선은 외층의 분할선으로부터 약 5밀리미터가 분지(off-set)된 것을 특징으로 하는 커버.
