Claim:
A cushion unit, comprising: a shell having an outboard surface and an inboard surface, wherein the outboard surface of the shell forms an outer surface of the cushion unit, wherein the inboard surface of the shell forms a cushion-receiving volume for the cushion unit; and a hinge seam body connected to the inboard surface of the shell, wherein the hinge seam body includes a fastener portion, wherein the connection of the hinge seam body to the inboard surface of the shell results in the cushion-receiving volume being partitioned to form a first cushion-receiving sub-volume forming a first cushion retaining portion, and a second cushion-receiving sub-volume forming a second cushion retaining portion, wherein the first cushion-receiving sub-volume and the second cushion-receiving sub-volume are demarcated by the connection of the hinge-seam body to the inboard surface of the shell; wherein the fastener portion includes a fastener support material that forms a first opening in the fastener portion, and a second opening in the fastener portion, wherein the fastener portion further includes a first fastener connected to the fastener support material proximate the first opening, and a second fastener connected to the fastener support material proximate the second opening.
