Seat trim tensioner

A vehicle seat, comprising:

• a cushion assembly comprising a base cushion and an extendable cushion, wherein the extendable cushion moves relative to the base cushion to extend a length of the cushion assembly;
• a seat frame supporting the cushion assembly;
• a segment of textile material enclosing the cushion assembly, wherein the segment of textile material comprises a bridging segment of textile material that spans a space between the base cushion and the extendable cushion;
• and
• a tensioner comprising:
• a roller receiving the segment of textile material, wherein the roller rotates relative to the seat frame about an axis of a shaft;
• a spring connected to the roller and the shaft, wherein the spring exerts a tensioning force on the segment of textile material biasing the segment of textile material to be rolled around the roller when retracting the segment of textile material, and wherein the tensioning force of the spring resists extending the segment of textile material and holds the segment of textile material in tension as the segment of textile material is extended;
• and
• at least one trim wire attached to the segment of textile material, such that the at least one trim wire is adapted to provide a flexible support to the segment of textile material in an extended position of the segment of textile material.
