The invention concerns a device, preferably arranged for setting inclination of a backrest of a seat, primarily a vehicle seat, comprising components which are interconnected in pairs for mutual rotational movement and which are arranged to be associated with the back rest and the seat face, respectively, of the seat. Each component of the pair is formed with a gear rim, the rims positioned adjacent one another in mutual concentric relationship, with the rim teeth meshing with the teeth of a number of planet wheel pairs, the latter rolling in mesh with the associated gear rim, thus causing the two gear rims and their associated component of the joint to turn relatively to one another, and consequently the back rest of the seat to pivot with respect to the seat part.

A device for relative angular setting of two units, preferably the inclination of a back rest of a seat, particularly a vehicle seat, comprising components that are interconnected in pairs for mutual rotational movement, said components preferably being separate fitting components which are arranged to be associated with the back rest and a seat face, respectively, of the vehicle seat, characterized in that each component of said pair of integrated components is formed with a gear rim, each with a different number of teeth, said rims being positioned adjacent one another in mutual concentric relationship with the rim teeth meshing with a number of planet wheel pairs, wherein each pair comprises two planet wheels, said wheels likewise being positioned adjacent one another in mutual concentric relationship and being non-rotationally interconnected, the planet wheels being supported by a common support member, and an actuator arranged to move the planet wheels along their respective gear rim, whereby the rolling of the planet wheel/wheels in mesh with the associated gear rim causes the two gear rims and the associated components of the joint to turn with respect to one another and consequently the back rest of the vehicle seat to pivot with respect to the seat face.
