Abstract
A fitting system for a vehicle seat having a fitting (10), which has a first fitting part (11) and a second fitting part (12), which fitting parts can be locked to one another and can be rotated relative to one another about an axis (A). A transmission rod (7) rotates during an unlocking process to unlock the fitting (10) against the torque and follows a characteristic curve (M35) generated by a spring arrangement (35). A hand lever (5) initiates the unlocking process, the actuation of which rotates the transmission rod (7). A shaped spring (61) is active between a first component (63) and a second component (64) which rotate, relative to one another during the unlocking process. The torque generated by the shaped spring follows a non-linear characteristic curve (M61) which, together with the approximately linear characteristic curve (M35) of the spring arrangement (35), produces an overall characteristic curve (Moverall).
