ABSTRACT:
A hinge for a seat, particularly a power vehicle seat, has a stationary hinge member associated with a seat part of the seat, a pivotable hinge member associated with a backrest part of the seat, a pivot axle pivotally connecting the hinge members with one another, an adjusting and fixing device arranged to determine a position of the hinge members relative to one another and formed as a wobble transmission including an eccentric member associated with a cam region of the pivot axle and rotatable together with the latter, an accumulator arranged in the cam region of the pivot axle to radially adjust an eccentricity which determines an engaging point of the wobble transmission and formed as an eccentric ring with an inner longitudinal opening in direction of eccentricity and surrounding a centric portion of the pivot axle, a pressing member located between the longitudinal opening and the centric portion of the pivot axle and arranged to be pressed by the accumulator for maintaining an extreme eccentricity in immovable condition, and a cam member arranged to connect in case of adjusting the eccentric ring with the centric portion of the pivot axle against the action of the accumulator with reducing of the eccentricity and in a torque-transmitting manner.
