ABSTRACT:
A seat device (12) including a seat back (16) having an upper seat back frame portion (34), a lower seat back frame portion (36), and a pivotal connection for pivotally supporting and connecting the upper seat back frame portion (34) to the lower seat back frame portion (36) about a pivot pin (38). A positioner extends between the two seat back frame portions and is provided with at least one motor (66), connected to a threaded shaft (62), which drives the positioner. The motor (66) is resiliently mounted to one of the seat back frame portions (34,36) using flexible bushings (80) which absorb the play between the upper and lower seat back frame portions (34,36) when the two are pivoted relative to one another.
