Abstract

Patente de Invenção: "TENSOR ROTATIVO COM ACIONAMENTO DE CORPOS DE MASSA". Em um tensor rotativo para um cinto de segurança, especialmente em veículos automotores, com um enrolador de cinto, cuja árvore de enrolamento de cinto na liberação do tensor rotativo ali acoplado, é girada por um acionamento correspondente na direção de enrolamento do cinto de segurança, consistindo o acionamento de uma roda propulsora com endentação externa, destinada à árvore de enrolamento do cinto, e de um canal que envolve a roda propulsora ao menos em uma circunferência parcial, destinado à passagem de corpos de massa, acelerados na liberação dentro do canal e estabelecendo contato de cooperação com a endentação externa da roda propulsora, está previsto que para o comando sincronizado, de forma congruente, dos corpos de massa (18) na endentação externa (13) da roda propulsora (11) está previsto um elemento perfilador (16),constituído de um corpo de massa (*18) e de um componente buscador (17,28) em movimento de avanço.
