| description | A seat member and backrest member are connected by mounting means mounting the latter on the former with freedom of angular displacement relative thereto. The mounting means includes a ring gear on one of the members and having inwardly directed teeth, and a spur gear provided on the other member received within the ring gear and having outwardly directed teeth which mesh with those of the ring gear. The outer diameter of the spur gear is smaller than the root diameter of the ring gear by at least the height of one tooth and of the number of inwardly directed teeth differ from the number of outwardly directed teeth by at least one. An internal chamber is provided in one of the gears and a journalling member is accommodated with radial clearance in the chamber and movable radially therein. It is smaller than the interior dimension of the chamber by at least the difference between the diameters of the gears. A pivot is provided on one of the gears and has a portion journalled in the journalling element. A selectively operable locking arrangement is provided, including a plurality of wedge-shaped locking elements located in the chamber in the radial clearance and a handle is provided for effecting movement of the locking elements between locking and unlocking positions. |
