Abstract
Patente de Invenção: <B>"ALMOFADAS DE AIRBAG DE BAIXA PERMEABILIDADE TENDO COBERTURAS DE FILME DE ESPESSURA EXTREMAMENTE BAIXA"<D>. Panos infláveis de cobertura (26), mais particularmente airbags aos quais quantidades muito baixas de acréscimo de cobertura foram aplicadas são providos, os quais exibem permeabilidades ao ar extremamente pequenas. Os panos se prestam basicamente ao uso em almofadas de restrição automotivas que requerem características de permeabilidade baixas (como por exemplo os airbags de cortina lateral). O pano utiliza uma cobertura económica, muito fina a fim de prover tais níveis de permeabilidade baixos necessários. Sendo assim, o airbag revestido inventivo possui uma cobertura de no máximo 70,87g (2,5 onças por jarda quadrada), mais preferivelmente cerca de 22,67 g (0,8 onças por jarda quadrada), e exibe um tempo de vazamento de pelo menos 7 segundos. Todas as coberturas, em particular coberturas de não silicone, elastoméricas, e os airbags revestidos, atendendo a estes critérios, pretendem estar dentro do âmbito da presente invenção.Invention Patent: <B> "LOW PERMEABILITY AIRBAG CUSHIONS HAVING EXTREMELY LOW THICK FILM COVERINGS" <D>. Inflatable cover sheets (26), more particularly airbags to which very low amounts of added coverage have been applied are provided, which exhibit extremely small air permeabilities. The cloths are primarily suitable for use in automotive restraint pads that require low permeability characteristics (such as side curtain airbags). The cloth uses an economical, very thin covering in order to provide such necessary low permeability levels. Therefore, the inventive coated airbag has a coverage of a maximum of 70.87g (2.5 ounces per square yard), more preferably about 22.67 g (0.8 ounces per square yard), and exhibits a leak time at least 7 seconds. All covers, in particular non-silicone, elastomeric covers, and coated airbags, meeting these criteria, are intended to be within the scope of the present invention.
