Abstract

L'invention concerne un siège de sécurité (1) présentant une fonction d'amortissement des chocs et un procédé d'amortissement des chocs associé. Le siège de sécurité (1) comprend un siège configuré pour accueillir un conducteur. Une ceinture mobile (11, 13, 14, 15) présentant une fonction de fixation, de retenue ou de raccordement est disposée sur le siège ou au niveau de la partie inférieure du siège. Un amortisseur de chocs (2) est disposé sur la ceinture mobile (11, 13, 14, 15) et/ou au niveau d'une extrémité de raccordement pour raccorder la ceinture mobile (11, 13, 14, 15). Lorsque l'amortisseur de chocs (2) est utilisé normalement sur le siège de sécurité (1), l'amortisseur de chocs (2) est dans un état naturel. Lorsque le siège subit une collision ou une décélération soudaine, l'amortisseur de chocs (2) donne à la ceinture mobile (11, 13, 14, 15) une certaine amplitude, et lorsque l'amplitude de la ceinture mobile (11, 13, 14, 15) atteint un degré prédéterminé, l'amortisseur de chocs applique progressivement une tension à la ceinture mobile (11, 13, 14, 15) de manière à ramener la ceinture mobile dans sa position d'origine. Le siège permet à une ceinture mobile de s'adapter à la situation dans laquelle un corps humain s'incline vers l'avant en raison de l'inertie, amortit les dommages dus aux chocs subis par des parties d'un corps humain en raison de ceintures mobiles telles qu'une ceinture de sécurité, une bretelle ou une ceinture de hanches, et assure une fonction de retenue. Par rapport à un siège de véhicule classique, le siège selon l'invention présente une sécurité améliorée.
