Abstract

Patente de Invenção:<B>"ALMOFADAS DE AIRBAG DE BAIXA PERMEABILIDADE QUE APRESENTAM NìVEIS DE REVESTIMENTO EXTREMAMENTE BAIXOS"<D>. São providos tecidos infláveis revestidos (26), mais particularmente, airbags, aos quais foram aplicadas quantidades adicionais muito baixas de revestimento, os quais exibem uma permeabilidade do ar extremamente baixa. Os tecidos da invenção são principalmente para uso em almofadas de limitação usadas em automóveis que exigem características de baixa permeabilidade (tais como airbags de cortina lateral). Tradicionalmente, os revestimentos pesados e, conseq³entemente, dispendiosos, de compostos, tais como neopreno, silicones e semelhantes, foram utilizados para proverem tais níveis de baixa permeabilidade exigidos. Dessa forma, o airbag revestido da invenção apresenta um revestimento de no máximo 70 gramas por 0,8361 metros quadrados (2,5 onças por jarda quadrada), mais preferivelmente de cerca de 22,6 gramas por 0,8361 metros quadrados (0,8 onças por jarda quadrada), e exibe um tempo de vazamento (uma medição do tempo exigido para que toda a quantidade de gás introduzida dentro do airbag na pressão máxima durante a inflação escape do airbag em 0,6804 atm (10 psi) de pelo menos 7 segundos. Todos os revestimentos, em particular os revestimentos de não-silicone elastoméricos, e os airbags revestidos, que atendem a estes critérios, se destinam a residir no escopo desta invenção.Invention Patent: <B> "LOW PERMEABILITY AIRBAG PADS THAT HAVE EXTREMELY LOW COATING LEVELS" <D>. Coated inflatable fabrics (26) are provided, more particularly, airbags, to which very low additional amounts of coating have been applied, which exhibit extremely low air permeability. The fabrics of the invention are mainly for use in limitation pads used in automobiles that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy and, consequently, expensive coatings of compounds, such as neoprene, silicones and the like, have been used to provide such required low permeability levels. Thus, the coated airbag of the invention has a coating of a maximum of 70 grams per 0.8361 square meters (2.5 ounces per square yard), more preferably about 22.6 grams per 0.8361 square meters (0, 8 ounces per square yard), and displays a leak time (a measurement of the time required for the entire amount of gas introduced into the airbag at maximum pressure during inflation to escape the airbag at 0.6804 atm (10 psi) of hair at least 7 seconds All coatings, in particular elastomeric non-silicone coatings, and coated airbags, which meet these criteria, are intended to reside within the scope of this invention.
