  • the presenter mechanism is particularly, but not exclusively, intended for
  • a presenter mechanism comprising a presenter arm, means for moving the arm from a stowed position to an operative position in which an element supported on the arm is presented, and control means for controlling the means for moving in response to a plurality of signals.
  • the mechanism is a vehicle seat belt presenter mechanism.
  • the means for moving comprises a motor which drives the arm through a flexible drive and a worm and gear.
  • the control means is an electronic control unit and sensors are provided to feed signals to the control means to indicate when the vehicle door is closed, when the seat is occupied and when the available voltage is above a certain level.

Abstract

Un véhicule comprend des mécanismes présentateurs de ceinture de sécurité, chaque mécanisme comprenant un bras (5) conçu pour être déplacé d'une position de blocage à une position de fonctionnement lorsqu'une porte de véhicule correspondante s'avère être fermée au moyen d'un commutateur de porte, et lorsqu'un siège correspondant s'avère être occupé au moyen d'un commutateur de coussin de siège. Le bras (5) est déplacé d'une position de blocage à une position de fonctionnement au moyen d'un moteur par l'intermédiaire d'un système de commande flexible (3) et d'une boîte d'engrenage à vis sans fin et roues dentées (4). Le bras comprend un taquet (7) venant se loger dans des fentes de la roue d'engrenage et est fixé par l'intermédiaire de rondelles de friction (11) qui permettent au bras présentateur (5) de se maintenir en position de fonctionnement que le moteur et le système d'entraînement ramènent à la position de blocage, prêt pour la prochaine mise en marche. Des éléments sont ménagés pour permettre au bras de revenir à la position de blocage si la ceinture de sécurité n'est pas bouclée dans une certaine limite de temps de présentation du bras. Le mécanisme assure un agencement compact et approprié facilitant le port des ceintures de sécurité.
