Reduced noise drive block for vehicle seat adjuster

摘要

A drive apparatus suitable for a power seat adjuster includes a rotatably threaded shaft disposed between an upper track movably mounted with respect to a stationary lower track. Coaxial apertures are formed in opposed side legs of a housing fixed to the lower track. A drive block having a bore threadingly engaged with the threaded shaft is disposed in the housing and in coaxial alignment with apertures in two side legs of the housing. A resilient cushion fills the housing and surrounds the drive block to vibrationally isolate the drive block from the housing and the lower track.
