Abstract

코어층을 별체 성형해 두도 인서트 성형할 필요가 없고 제조 공정수가 대폭 삭감가능한 동시에 사출 성형 금형도 가단해지는 에어백 장치용 패드를 제공한다.The present invention provides a pad for an airbag apparatus, in which the core layer is not separately molded and there is no need for insert molding, and the number of manufacturing steps can be greatly reduced, and the injection molding mold is also reduced.

에어백 장치(11)의 상면을 덮는 패드이며 패드 전체(13)가 에어백(15)의 팽출시에 파단되어서 상벽부(17)를 전개 가능으로 하는 전개용 홈부(19)를 연속적으로 구비하고 있는 에어백 장치용 패드에 있어서, 패드 본체(13)가 저온인장강도 TB(-35℃) : 200∼500kgf/㎤의 스티렌계 또는 폴리에스테르계의 열가소성 탄성중합체(TPE)이며 상벽부 평균 두께는 2.5~6mm가 되게 단층 형성되어 이룬다. 그리고, 전개용 홈부(19)의 잔존두께(t)가 0.3∼1.5mm 이고 뒤측 개선각도가 30∼90°이다.The airbag which covers the upper surface of the airbag apparatus 11, and is provided continuously with the unfolding groove part 19 which makes it possible to develop the upper wall part 17 when the whole pad 13 breaks at the time of the airbag 15 expansion. In the pad for an apparatus, the pad body 13 is a low-temperature tensile strength T B (-35 ° C.): styrene or polyester thermoplastic elastomer (TPE) of 200 to 500 kgf / cm 3 and the average thickness of the upper wall is 2.5 to It consists of a single layer to be 6mm. And the remaining thickness t of the unfolding groove part 19 is 0.3-1.5 mm, and the back improvement angle is 30-90 degrees.
