D.4.1.4.2 Seating Subsystem (HEV Fusion)
Figure D-41: Hook and Loop Placement
Due to cooling requirements of the traction battery, air is drawn from under the rear seat
bottom into the battery case. To accommodate the air flow, the rear seat base structure is
molded from expanded polypropylene (EPP). This allows for an air duct to be molded
into the base (Figure D-42 and Figure D-43). A polyurethane (PUR) foam cushion is
then placed on the EPP base. Driven by the lack of a conventional wire frame for seat
mounting, four (4) formed retainers and fasteners are mounted to the seat base (Figure
D-44). The seat cover is mounted to the foam seat cover with hook and loop retention
while the base employs extruded retainers which fit molded slots in the base. The
extruded retainers are sewn onto the seat cover (Figure D-45 through Figure D-47). To
close out the seat air duct a molded plastic intake grill (Figure D-48) is secured with push
pins to the seat base.
