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.

A seat comprising:
- a lower seat back frame;
- an upper seat back frame pivotally connected to the lower seat back frame about a pivot axis;
- a motor positioned in one of the lower or upper seat back frames by a boss and at least one flexible bushing disposed between the motor and the one seat back frame, the motor having a threaded rotary output;
- and
- a nut received on the threaded rotary output and engaged with the upper seat back frame and maintenance at a predetermined distance from the pivot axis by a bracket extending from said axis such that rotation of the rotary output moves the nut therealong and whereby the predetermined distance is permitted to remain constant by deformation of said flexible bushing.
