Fitting system for a vehicle seat

1. A fitting system for a vehicle seat, having at least one fitting, by which a backrest of the vehicle seat can be pivoted relative to a seat member of the vehicle seat from at least one position for use into a non-use position, wherein the fitting comprises:

a first fitting member having a toothed ring;

a second fitting member, wherein the first fitting member can be rotated relative to the second fitting member about an axis;

at least one movable bar, which the second fitting member guides and which locks the fitting in the at least one position for use by cooperation with the toothed ring;

a pretensioned, rotatably supported eccentric which, by a rotation in the closure direction, moves the at least one bar radially outward in order to cooperate with the toothed ring; and

a rotatably supported control cam which, when rotated in an opening direction, moves the at least one bar radially inward in order to end the cooperation with the toothed ring,

wherein the control cam in a state decoupled from the eccentric can be rotated in the closure direction in order to lock the fitting in the non-use position by cooperation of the at least one bar with the toothed ring,

wherein the eccentric and the control cam are at least temporarily coupled by way of a clamping lever and a control lever provided outside the fitting and axially offset with each other, and

wherein the clamping lever is connected to the eccentric and the control lever is connected to the control cam.

2. The fitting system as claimed in claim 1 , wherein the control cam has at least one slotted control member which cooperates with a projection of the at least one bar, wherein, when the fitting is locked in the non-use position, the abutment angle between the edge of the slotted control member and the adjacent projection is located within the self-locking range or slightly outside the self-locking range.

3. The fitting system as claimed in claim 1 , wherein the eccentric has an eccentric actuation member which protrudes outward from the fitting, and the control cam has a cam actuation member which also protrudes outward from the fitting.

4. The fitting system as claimed in claim 3 , wherein there is provided a first actuation element which is operationally connected to the clamping lever which is connected to the eccentric actuation member in a rotationally secure manner.

5. The fitting system as claimed in claim 4 , wherein the clamping lever and the control lever are coupled for entrainment by at least one of a coupling spring and a slot/pin guide which has a free travel path.

6. The fitting system as claimed in claim 5 , wherein the control lever can be pivoted at least one of by a control spring, by a control arm, and within the free travel path of the slot/pin guide in each case in a manner decoupled from the clamping lever.

7. The fitting system as claimed in claim 3 , wherein a second actuation element is operationally connected to the control lever, which is connected to the cam actuation member in a rotationally secure manner.

8. The fitting system as claimed in claim 7 , wherein there is provided an actuator which, owing to a control signal which is transmitted by at least one sensor, pivots the control lever, in particular with the actuator acting on a control arm of the control lever.

9. The fitting system as claimed in claim 3 , wherein, between the backrest and the seat member, a control segment and a pivotable locking lever cooperate and move relative to each other when the backrest is pivoted, wherein the control segment locks the locking lever in the positions for use provided, and wherein the control segment releases the locking lever during movement in the non-use position, which lever then locks the eccentric actuation member.

10. A vehicle seat having a seat member and a backrest which, by a fitting system as claimed in claim 1 , is fitted to the seat member, can be pivoted relative thereto and can be locked with various inclination adjustments.
