Abstract
Patente de Invenção: "MéTODO E APARELHO PARA A VERIFICAçãO DE PESO DE OCUPANTE DE ASSENTO". A presente invenção trata de um sistema de verificar o peso do ocupante do assento que é usado para controlar o desdobramento do saco de ar de segurança. O sistema inclui um fundo de assento que recebe uma força de peso de ocupante de assento vertical. O referido assento é dividido em quarto quadrantes, o quadrante dianteiro direito, o quadrante dianteiro esquerdo, o quadrante traseiro esquerdo e o quadrante traseiro direito. Cada quadrante inclui um sensor que gera um sinal de peso que corresponde em magnitude ao peso do ocupante do assento no respectivo quadrante. Cada sinal de peso é compreendido de um componente de força vertical e um componente de erro induzido pelas forças de frenagem ou desaceleração que atuam no fundo do assento em uma direção não vertical. Os sensores são orientados dentro de seus respectivos quadrantes de modo que dois sensores geram uma leitura de erro positivo e dois sensores geram uma leitura de erro negativo. Quando os sinais de peso de cada quadrante são adicionados juntos para determinar o peso total do ocupante do assento, o erro é eliminado como os componentes de erro positivo e negativo para cancelar um ao outro. O peso do ocupante do assento é determinado ao se adicionar os componentes de força verticais a partir de cada um dos sinais de peso juntos.
