Abstract
A hinge for adjustably mounting a backrest component on a seat component of a vehicle seat includes two hinge members respectively connected to the components of the seat. One of the hinge members includes a hinge element and two spur gears which flank the hinge element, are mounted on an eccentric rotatably mounted on the other hinge member, and are connected to the hinge element for joint turning. The other hinge member includes two hinge portions which embrace the hinge element of the one hinge member and each of which has an internal gear annulus which meshes with one of the spur gears. The hinge portions of the other hinge member are turntable relative to one another for eliminating play between the teeth of the spur gears, on the one hand, and of the internal gear annuli, on the other hand. An elongated body of elastically yieldable material is connected, at its ends, to the hinge portions of the other hinge member and maintains the same in the respective play-eliminating position relative to one another.
