Abstract
A power seat adjuster includes a drive shaft rotatably driven by a motor mounted centrally on a bracket fixedly connected at opposite ends to the moveable track of a pair of vehicle seat track assemblies. The drive shaft threadingly engages a drive nut mounted in a resilient holder carried on a bracket fixedly connected to the stationary tracks of the track assemblies. The resilient holder for the drive nut provides self-alignment of the drive nut in at least one and preferably two or more mutually exclusive axes or planes relative to the drive shaft.
