Adjustable hinge for a backrest of a vehicle seat
First Claim
1. A hinge for adjustably mounting a backrest component on a seat component of a seat, particularly of a vehicle seat, comprising, in combination, two hinge members each rigidly connected to one of the components of the seat and each having a pair of gear sections, each section of one of said pairs having an internal gear annulus, and each section of the other of said pairs having an external gear annulus;
- and an eccentric mounted on one of said hinge members for rotation about a pivot axis and having a pair of eccentric surfaces each centered on an eccentric axis parallel to and radially offset from said pivot axis and each supporting one of said gear sections of the other hinge member for relative turning and for orbiting of said external gear annuli relative to and in mesh with said internal gear annuli;
said other hinge member including a hinge element and two spur gears which have said other pair of gear sections and which axially flank said hinge element, being so connected to the latter as to entrain the same for turning about said pivot axis; and
said one hinge member including a pair of hinge portions which axially embrace said other hinge member and each having one of said gear sections of said one pair of gear sections.

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.
