Mechanism for angular adjustment of position of back with regard to base in passenger compartment of car, has coaxial cam presenting angular play of displacement with regard to another coaxial cam such that each coaxial cam is movable

摘要

The mechanism (1) has a frame (2), and a set of functional units (4) that is intended for fulfilling a technical function. A set of coaxial cams (6) is piled up radially. A main cam (8) and a secondary cam (10) are provided, where the secondary cam are driven in rotation by the main cam. Each of the coaxial cams presents an angular play of displacement with regard to another coaxial cam such that each coaxial cam is movable in rotation from a nominal position in a direction of rotation independent of other cams.
