Abstract

Selon la présente invention, la plaque d'ailette supérieure (10) d'une glissière (400) est pourvue de première à quatrième protubérances (110, 120, 130, 140). Les première à quatrième protubérances (110, 120, 130, 140) sont pourvues de premier à quatrième évidements de mise en prise (111, 121, 131, 141) dans lesquels les première à quatrième protubérances de mise en prise (211, 221, 231, 241) d'un ressort à lame (200) sont agencées. Les premier à quatrième évidements de mise en prise (111, 121, 131, 141) sont disposés de manière à définir une plage verticale dans laquelle les première à quatrième protubérances de mise en prise (211, 221, 231, 241) peuvent se déplacer lorsqu'une languette de traction (300) est actionnée de façon pivotante. Dans un autre exemple, les troisième et quatrième protubérances (130, 140) sont empilées, et les troisième et quatrième évidements de mise en prise (131, 141) et les troisième et quatrième protubérances de mise en prise (231, 241) sont omis.
