Abstract
A detent hinge assembly includes a spring that biases one or more needle rollers into engagement with the outer surface of the hinge shaft. The needle rollers engage one or more grooves in the surface of the hinge shaft to provide the detent function of the hinge. The spring is in the form of a resilient band that surrounds at least a portion of the circumference of the hinge shaft. The spring is provided with a depression that faces the surface of the hinge shaft and that receives a portion of the needle roller.
