A DEVICE FOR RELATIVE ANGULAR SETTING OF TWO UNITS, PREFERABLY THE INCLINATION OF A VEHICLE SEAT BACKREST

摘要

The invention concerns a device, preferably arranged for setting the inclination of the backrest of a seat, primarily a vehicle seat, comprising components (1, 3) which are interconnected in pairs for mutual rotational movement and which are arranged to be associated with the backrest and the seat face, respectively, of the seat. In accordance with the invention each component of said pair is formed with a gear rim (5, 6), said rims positioned adjacent one another in mutual concentric relationship, with the rim teeth meshing with the teeth of a number of planet wheel pairs (7, 8), 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 backrest of the seat to pivot with respect to the seat part proper.
