Title
(EN) SELF-ALIGNING DRIVE NUT FOR VEHICLE POWER SEAT ADJUSTER
(FR) ECROU DE COMMANDE AUTO-CENTREUR POUR DISPOSITIF DE REGLAGE DE SIEGE DE VEHICULE ACTIONNE PAR MOTEUR
Abstract
(EN)
A power seat adjuster (10) includes a drive shaft (160) rotatably driven by a motor (150) mounted centrally on a bracket (152) fixedly connected at opposite ends to the moveable track (52) of a pair of vehicle seat track assemblies (46, 48). The drive shaft (160) threadingly engages a drive nut (178) mounted in a resilient holder (170) carried on a bracket (164) fixedly connected to the stationary tracks (50) of the track assemblies. The resilient holder (170) for the drive nut (178) provides self-alignment of the drive nut (178) in at least one and preferably two or more mutually exclusive axes or planes relative to the drive shaft (160).
(FR)
Ce dispositif de réglage de siège actionné par moteur (10) comprend un arbre d'entraînement (160) entraîné en rotation par un moteur (150) monté de façon centrale sur un support (152) accouplé à demeure au niveau de ses extrémités opposées à la glissière mobile (52) d'une paire d'ensembles glissières pour siège de véhicule (46, 48). L'arbre d'entraînement (160) se visse dans un écrou de commande (178) monté dans un élément de retenue élastique (170) porté par un support (164) accouplé à demeure aux glissières fixes (50) des ensembles glissières (46, 48). L'élément de retenue élastique (170) de l'écrou de commande (178) assure l'auto-centrage de ce dernier sur au moins un axe ou plan par rapport à l'arbre de commande (160), et de préférence sur au moins deux axes ou plans qui s'excluent mutuellement.
