Abstract

trata-se de um conjunto de retrator de pré-tensionamento de cinto de segurança para uso em um veículo de passageiros. o conjunto de pré-tensionamento inclui um tubo em comunicação fluida com um gerador de gás e um elemento de acionamento disposto no mesmo que se desloca em uma primeira direção em resposta à atuação pelo gerador de gás. o elemento de acionamento inclui uma haste de polímero com uma porção rebaixada. um batente é acoplado a uma porção de extremidade da haste de polímero. o tubo inclui uma projeção que se estende dentro do tubo em posição adjacente à saída para definir uma porção de constrição. a porção de constrição é dimensionada para permitir que a porção rebaixada da haste de polímero passe através da mesma ao mesmo tempo em que restringe a passagem do batente através da mesma. a haste de polímero tem um recurso de retenção para engatar de modo liberável a projeção.
