Title (EN) METHOD OF MAKING VEHICLE HEADREST
(FR) PROCEDE DE FABRICATION D'UN APPUI-TETE POUR VEHICULE
Abstract:
(EN) A method for forming a vehicle headrest having an improved appearance over the prior art includes the steps of making a shell (22) with two small openings (27) in a bottom wall. The post for mounting the headrest to a vehicle seat is a generally U-shaped item. One leg (26) of the post is inserted through one of the small openings (27) in the shell, and the post is manipulated relative to the shell such that the leg is caused to extend outwardly of the second small opening (27). Once the post is properly received within the shell, foam (44) is injected into the shell to fill the cavity. Since there is no large opening required in the shell for insertion of the post, no seams must be covered, concealed or closed to result in acceptable appearance for the final headrest.
(FR) Procédé de fabrication d'un appui-tête pour véhicule dont l'aspect est amélioré par rapport aux appuis-tête actuels. Ce procédé comprend les étapes suivantes: fabrication d'une coque (22) pourvue de deux petits orifices (27) sur sa partie fond. Le support permettant de positionner l'appui-tête sur le siège d'un véhicule est généralement en forme de U. L'un des montants (26) de ce support est inséré dans l'un des deux petits orifices (27) se trouvant sur la coque et le support est manipulé par rapport à la coque pour que ce même montant ressorte par le second petit orifice (27). Une fois que le support est bien positionné dans la coque, on injecte dans celle-ci une mousse destinée à remplir la cavité. Dans la mesure où l'insertion du support ne nécessite pas de grande ouverture dans la coque, il n'y a aucune ligne d'assemblage à couvrir, à dissimuler ou à fermer pour que l'appui-tête une fois terminé ait un aspect acceptable.
