Abstract
A first mounting member can be secured to a backrest member of a seat, such as a seat of an automotive vehicle, and a second mounting member can similarly be secured to the seat member of the seat. A ring gear is provided on one of the mounting members and has inwardly directed teeth, and the other mounting member has a spur gear received within the ring gear and having outwardly directed teeth which mesh with play with the inwardly directed teeth. The spur gear has an outer diameter smaller than the root diameter of the ring gear by at least the height of one tooth and the number of inwardly directed teeth is different from the number of outwardly directed teeth by at least one. An eccentric arrangement is provided, extending through the gears and being movable to and from a position in which it effects relative radial displacement of the gears to such an extent as to eliminate the aforementioned play.
