Anthropomorphic upper seatback
A vehicle seating assembly includes a seatback frame. An articulating upper thoracic region is operably coupled with the seatback frame and includes a cross-vehicle support, a torso vertical support, and a suspension support. The articulating upper thoracic region is pivotally coupled with a mid-portion of the seatback frame between stowed and deployed positions. A back panel is operably coupled to a rear side of the seatback frame. A front close-out panel is disposed between a rear portion of the articulating upper thoracic region and the back panel. A peripheral gap is disposed between the front close-out panel and the articulating upper thoracic region.
