Abstract

L'invention concerne une charnière (10) pour un capot avant de véhicule, comprenant une partie supérieure de charnière (12), disposée côté capot, et une partie inférieure de charnière (14), disposée côté carrosserie, qui sont reliées l'une à l'autre par l'intermédiaire d'un premier levier cinématique (20) et d'un deuxième levier cinématique (60). Selon l'invention, un premier dispositif de verrouillage (40) libère, dans une position de travail, un mouvement de rotation du deuxième levier cinématique (20) et bloque, dans une position de protection de piéton, le mouvement de rotation du deuxième levier cinématique (20). Le premier dispositif de verrouillage (40) est accouplé à un levier de verrouillage et/ou de déverrouillage (50) par l'intermédiaire d'un levier de raccordement (30). Dans une situation d'accident, le levier de verrouillage et/ou de déverrouillage (50) fait passer le premier dispositif de verrouillage (40), par l'intermédiaire du levier de raccordement (30), de la position de travail à la position de protection de piéton.
