Abstract

tensionador. um tensionador compreendendo uma base (7), um braço pivô (1), engatado de modo pivotante com a base, uma mola de torção (9) engatada entre a base e o braço pivô, a mola de torção descarregável pelo movimento do braço em uma direção de desenrolar, um mecanismo de amortecimento (8) engatado de modo friccional com uma superfície interna de braç (11) e um engate de pressão com a base, e ainda suportando um batente (71) na base, e o mecanismo de amortecimento impelido radialmente para fora em engate com a superfície interno do braço quando a mola de torção é carregada na direção de desenrolar e por um movimento pivotante do mecanismo de amortecimento em torno do batente (71).
