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. | 07-12-2012 |
