  • Patent number: 7775591
    Abstract: In a fitting connected at one side to a backrest structure of a backrest and at the other side to the supporting structure of a seat part, having a first actuating element, by way of which the fitting can be activated to adjust the inclination of the backrest between use positions in a first angle range, having a second actuating element, by way of which the fitting can be activated so as to pivot the backrest freely from a use position in the first angle range into a pivoted-free position in a second angle range, and having a ring which is rotatably mounted on the fitting, when the fitting is activated, the second actuating element couples the backrest to the ring, so that the backrest, as it is pivoted freely, drives the ring at least when the second angle range is reached, and the ring then unlocks a longitudinal adjuster.
