Title
(EN) HEADREST ADJUSTMENT MECHANISM FOR VEHICLE SEATS
(FR) MÉCANISME DE RÉGLAGE D'APPUI-TÊTE POUR SIÈGES DE VÉHICULE
Abstract
(EN) A bushing allows for adjustability of a position of a headrest. The bushing includes a head portion having an opening and a passageway opening. The bushing also includes a body portion defining an internal passageway. The passageway opening of the head portion is aligned with the internal passageway of the body portion. The body portion includes a wall surrounding an area of reduced thickness, and a protrusion is located on an internal surface of the area of reduced thickness. The bushing also includes a moveable portion received in the opening of the head portion. The moveable portion is moveable between a first position where a feature engages a notch of a post receivable in the internal passageway of the body portion and the passageway opening of the head portion to retain the headrest in a position and a second position where the feature is disengaged from the notch of the post, allowing the post and the headrest to move relative to the bushing.
(FR) Selon l'invention, une douille permet l'aptitude au réglage d'une position d'un appui-tête. La douille comprend une partie tête ayant une ouverture et une ouverture de passage. La douille comprend également une partie corps définissant un passage interne. L'ouverture de passage de la partie tête est alignée avec le passage interne de la partie corps. La partie corps comprend une paroi entourant une zone d'épaisseur réduite, et une saillie est située sur une surface interne de la zone d'épaisseur réduite. La douille comprend également une partie mobile reçue dans l'ouverture de la partie tête. La partie mobile est mobile entre une première position dans laquelle un élément vient en prise avec une encoche d'un montant pouvant être reçu dans le passage interne de la partie corps et l'ouverture de passage de la partie tête de façon à maintenir l'appui-tête dans une position et une seconde position dans laquelle l'élément est désengagé vis-à-vis de l'encoche du montant, permettant au montant et à l'appui-tête de se déplacer par rapport à la douille.
