Anthropomorphic pivotable upper seatback support
First Claim
1. A vehicle seatback assembly, comprising:
- a static lower suspension assembly coupled to a seatback structure integral with the vehicle seatback assembly;
a dynamic upper suspension assembly operably coupled to an actuation assembly to rotate relative the static lower suspension assembly between a forward position and a rearward position; and
a split between the static lower seatback suspension assembly and the dynamic upper suspension assembly, wherein the split generally defines a laterally extending line that is disposed between 270 and 300 mm above an H-point at a reclining axis of the vehicle seatback assembly measured along a line extending substantially parallel to the seatback structure when the seatback structure is in an upright position, the laterally extending line extending substantially parallel to the reclining axis.

Abstract
A vehicle seating assembly includes a lower seat and a seatback structure extending upwardly relative the lower seat, the lower seat and the seatback structure defining a seat H-point, and the seatback structure having an upper seatback support, a lower seatback support, and a split between the upper seatback support and the lower seatback support. The split is disposed between 270 and 300 mm, preferably about 285 mm, above the H-point along a line extending substantially parallel to the seatback structure. The upper seatback support pivots about a pivot between a rearward position and a forward position relative the lower seatback support. A motorized actuation assembly is disposed within the seatback structure and operably coupled to the upper seatback support, wherein the motorized actuation assembly pivots the upper seatback support about the pivot between the rearward position and the forward position.

9. A vehicle seatback assembly, comprising:
-
a seatback structure defining an H-point at a reclining axis of the vehicle seatback assembly; a dynamic upper suspension assembly having a lower edge generally defining a laterally extending line disposed between 270 and 300 mm above the H-point measured along a line extending substantially parallel to the seatback structure, the laterally extending line extending along a line extending substantially parallel to the reclining axis, wherein the dynamic upper suspension assembly pivots about a pivot generally defining a pivot axis that is proximate and substantially parallel to the laterally extending line when the seatback structure is in an upright position, wherein the dynamic upper suspension assembly pivots between a forward position and a rearward position relative the seatback structure; and a motorized actuation assembly coupled with and controlling the position of the dynamic upper suspension assembly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
