A vehicle seat assembly, biasing mechanism and method of installing a vehicle seat assembly are provided. The first end region of the torsion spring is for fixed connection to a vehicle frame bracket mount such that the seat back rotates about a lateral axis relative to the first end region of the spring. The second end region of the torsion spring is offset from the transverse axis. The support bracket is connected to the seat back, wherein the middle region of the torsion spring is supported for rotation by the support bracket. A block is supported by the support bracket and offset from the transverse axis, wherein the block contacts the second end region of the torsion spring to bias the spring when the seat back is in the first use position.)
