(EN) Emergency inertial system for disconnecting a vehicle electric circuit from the electricity source
(FR) Système de sécurité inertiel pour déconnecter un circuit électrique d'une source électrique
Abstract
(EN) An emergency inertial system for disconnecting the electric circuit of a vehicle from the electricity source or battery (2) in the event of impact, to prevent sparks being generated by impact-induced shortcircuiting and so safeguard against fire; the system presenting a 360 DEG active inertial switch (10) in series with the electric circuit (3); and the inertial switch presenting a floating mass (20), first electric contact means (21) connected to opposite terminals of the electric circuit and separated by an insulating means, and second electric contact means (22) cooperating with the floating mass so as to switch from a first operating position wherein they shortcircuit the first electric contact means via the insulating means, and a second operating position wherein they are detached from the first electric contact means; the first electric contact means being defined by respective carbon brushes (21) of the type used for the sliding contacts supplying the rotors of electric motors.
