Abstract

Le problème à résoudre par la présente invention est de transmettre efficacement des vibrations à une personne assise dans un siège de véhicule et de supprimer la génération d'un bruit anormal provoqué par la transmission de vibrations d'un dispositif de génération de vibrations à un cadre de siège. La solution selon l'invention porte sur un siège de véhicule (1), comprenant : des cadres latéraux gauche et droit (26) s'étendant verticalement ; un cadre supérieur (27) s'étendant horizontalement, reliant l'une à l'autre les extrémités supérieures des cadres latéraux ; un élément de fil métallique (51) fixé à l'un des cadres latéraux et au cadre supérieur ; un élément de plaque (52) relié à l'élément de fil métallique et ayant une surface de support (58) ; et un dispositif (41) supporté par la surface de support.
