Claims (3)
- 우레탄재질로 주연부가 융착 되어 내부에 공간이 형성되는 외피가 형성되고, 내부에 길이방향으로 상하면이 융착 된 다수개의 내부판이 형성되며, 상기 외피에 부착되는 밸브와 상기 밸브의 끝단에 호스로 연결되는 공기주입기로 구성되는 것을 특징으로 하는 에어방석.
- 제 1항에 있어서,
상기 내부판에는 다수개의 홀이 형성된 것을 특징으로 하는 에어방석. - 길이방향으로 절단된 우레탄 원단을 펼쳐서 놓고, 다수개의 내부판을 우레탄원단의 절반까지 일정간격으로 배치하는 배치단계와;
상기 배치된 각 내부판의 일측주연부를 고주파융착하는 1차융착단계와;
상기 1차융착단계 후에 내부판이 접착되지 않은 면을 접어서 각 내부판의 상단에 위치시키고, 내부판의 타측주연부를 이 면에 고주파융착시키는 2차융착단계와;
상기 2차융착단계 후에 우레탄원단의 일측에 밸브를 삽입고정하는 밸브고정단계(d)와;
상기 우레탄원단의 개방된 부분을 모두 고주파융착하는 3차융착단계와;
상기 3차융착단계 후에 밸브에 호스를 연결하고, 끝단에 공기주입기를 고정하는 마무리단계로 구성되는 것을 특징으로 하는 에어방석 생산방법
