SEAT TRIM TENSIONER

A vehicle seat includes a seat frame supporting a base cushion and an extendable cushion that moves relative to the base cushion. Textile material encloses the cushion assembly and includes a bridging segment that spans a space between the base cushion and the extendable cushion. A tensioner includes a roller that receives the segment of textile material wrapped around the roller. The roller rotates on a shaft relative to the seat frame about an axis of rotation. A return spring is connected to the roller and the shaft to exert a tensioning force on the segment of textile material. The return spring biases the segment of textile material to be rolled around the roller when retracting. The return spring resists extending and holds the segment of textile material in tension when the segment of textile material is extended.
