Abstract

Patente de Invenção: <B>"DOBRAMENTO DE SACOS DE GáS ASSIM COMO PROCESSO E DISPOSITIVO PARA A EXECUçãO DO DOBRAMENTO"<D>. A invenção refere-se a um dobramento de sacos para um saco utilizado em um módulo de airbag assim como a um processo e a um dispositivo para a execução do dobramento. O saco de gás é dobrado em forma de anel no sentido de um eixo longitudinal imaginário, sendo que ele no lado interno e no lado externo do anel apresenta dobras separadas (10, 11) e sendo que o eixo longitudinal imaginário corre, preferivelmente, através da boca de insuflação (7) do saco de gás. O processo do dobramento é caracterizado pelo fato de que o saco de gás vazio é estendido no sentido de um eixo longitudinal imaginário e dobrado em pregas dentro de uma circunscrição, preferivelmente em um espaço com secção transversal anelar, no sentido do eixo longitudinal. Um dispositivo para o dobramento de um saco de gás apresenta um corpo moldado (1). Além disso, é previsto pelo menos um dispositivo que introduz o saco de gás (6) no corpo moldado, assim como pelo menos um dispositivo para a compressão do saco de gás no corpo moldado. A vantagem consiste no fato de que são necessários apenas poucas etapas de processo e um dispositivo simples para o dobramento.
