Abstract

Cet ensemble ressort d'inversion (10) comprend un logement, un élément élastique (12) et un actionneur (14). Le logement comporte un premier support (16), un second support (18), opposé au premier, un troisième support (20), et un quatrième (22) opposé au troisième. Le premier et le second support sont éloignés l'un de l'autre d'une distance Y. L'élément élastique possède une première et une seconde extrémité, il est plus long que la distance Y, et il est s'étend entre le premier et le second support, une de ses extrémités étant supportée par le premier support tandis que l'autre est supportée par le second support. L'actionneur est relié au logement et applique une certaine force sur l'élément élastique, dans deux directions, provoquant le déplacement de cet élément élastique entre une première et une seconde position.
