  • the present invention relates to protection arrangements for electric wires in vehicles, for example in motor vehicles.
  • Protection of electric wires is particularly pertinent in connection with routing wires between a chassis of a vehicle and a movable member pivotally mounted relative to the chassis, for example from a chassis to a door pivotally mounted to the chassis, or from a chassis to a trunk lid pivotally mounted to the chassis.
  • a routing path employed will usually pass through an open region between a chassis and a movable member pivotally mounted to the chassis.
  • Protection applied to protect wires in vehicles from mechanical damage is devised, for example, to mitigate damage caused by impact blows and chafing.
  • such protection is also typically designed to protect electric wires from water and/or moisture.
  • the protection is particularly important if the electric wires have insufficient isolation and/or if the wires are susceptible to guiding water into electric units connected to the electric wires.

Abstract

L'invention porte sur un agencement de routage de fil électrique (100) actionnable pour renfermer et router un agencement de fil électrique à partir d'un premier agencement électrique dans un châssis (310) d'un véhicule à un second agencement électrique dans un élément mobile (318), connecté de façon pivotante par rapport au châssis (310). L'agencement de routage de fil électrique (100) comprend une première partie de canal (110) connectée au châssis (310), et une seconde partie de canal (112) connectée à l'élément mobile (318), de telle sorte que des centres de la partie (110, 112) coïncident sensiblement mutuellement avec un axe de rotation (320) de l'élément mobile (318), de telle sorte que l'agencement de fil renfermé et routé par les parties de canal (110, 112) est torsadé autour de l'axe de rotation (320) lorsque l'élément mobile (310) est déplacé de façon pivotante par rapport au châssis (310). L'agencement de routage (100) est utile par le fait que l'agencement du câblage électrique est moins susceptible d'être dégradé par un rhéodurcissement en réponse au fait d'être torsadé de façon répétée par comparaison avec la situation où il est courbé de manière répétée de façon correspondante.
