Abstract
A compact torsion spring assembly is functionally disposed between a first member and a second member. The first member is rotatable relative to the second member and has a first spring engagement notch therein. A bracket fixed relative to the second member has a second notch therein. A tension spring is formed as a continuous coil of steel wire, defining an enlarged diameter first catch plate portion at a first end and a second catch plate portion at a second end. The spring is disposed between the first member and the second member, with the first catch plate portion engaging the notch in the first member and the second catch plate portion engaging the notch in the bracket, wherein the spring rotatively biases the first member relative to the the second member.
