    摘要: The static air dam includes at least one mounting feature, which is preferably at least one hole or slot to allow a fastener, such as a screw, bolt, rivet, weld, or other similar attachment devices, to secure the air dam to a wall of a jamb channel. Air passage through the jamb channel is prohibited or at least substantially inhibited by the static air dam that is designed to approximate the size and dimensions of the cross section of the jamb channel. At least one side of the air dam includes a tab or similar structure for securing the free end of the curl spring of a curl spring balance. The air dam includes integrally formed reinforcing elements that either abut or are adjacent to the side walls of the jamb channel. The air dam preferably includes a pair of flexible projections for engaging ears on the curl spring carrier.
