Further advantageous developments of the present invention will become apparent from the dependent claims and the following description of preferred embodiments. This shows, partially schematized:

1 a motor vehicle seat according to an embodiment of the present invention;

2 the motor vehicle seat with a seat back in a release position;

3 a method according to an embodiment of the present invention; and

4 a method according to another embodiment of the present invention.

1 shows a motor vehicle seat according to an embodiment of the present invention.

The motor vehicle seat has a seat bottom 1 on rails 2 slidably guided, a seat back 3 , which pivot on the seat bottom 1 is stored, a braking device 4 for braking the seat base 1 on the rails 2 , an actuator 5 that the braking device 4 solve or ventilate and this is coupled with her via a Bowden cable or a linkage, the present both with the reference numeral 6 are identified, a detection means in the form of a contact sensor 7 that detects whether an angle between seat back 3 and seat base 1 reaches or falls below a predetermined minimum angle or not, and a control means 8th for controlling the actuator 5 on, the one below with reference to 3 . 4 performs described method or is set up for this purpose.

The motor vehicle seat further includes a manual by an actuating means 9 releasable lock 10 between seat base 1 and seat back 3 on, with the seat back 3 only by loosening the lock 10 beyond a comfort area F to the seat bottom 1 pivoted out, by one of the actuating means 9 various adjustment means 11 is durchfahrbar.

The motor vehicle seat further has an actuating device 12 for manual release of the braking device 4 independent of the actuator 5 on.

A method for moving the seat bottom 1 on the rails 2 according to an embodiment of the present invention, by the control means 8th is performed in 3 shown:
In a step S10, it is checked whether by the actuating means 9 the lock 10 was solved.

If this is the case (S10: "Y"), it is switched to an active operation mode in which the control means 8th proceeds to step S20. Otherwise, the method or control means repeats 8th Step S10.

In step S20, by means of contact sensor 7 detects if the seat back 3 Having a predetermined release position by checking whether the angle that they with the seat bottom 1 includes, less than or equal to a predetermined release angle E or not. This is smaller than a front comfort angle, the adjustment range F to the seat bottom 1 limited.

As long as this is the case (S20: "Y"), the control means is energized 8th in a step S30 the actuator 5 so that this is the braking device 4 solves. Then a user can the seat bottom 1 on the rails 2 move to facilitate access to a rear area behind the seat back 3 to create, as in 2 shown.

Once the through the contact sensor 7 detected angle that the seat back 3 with the seat bottom 1 includes, not less than or equal to the predetermined release angle E or vice versa greater than or equal to a predetermined closing angle is (S20: "N"), provides the control means 8th firmly that the seat back 3 has a predetermined closed position, and terminates the energizing of the actuator in a step S40 5 , This closes the actuator 5 the braking device 4 as these only by stationary energizing the actuator 5 is solved. Subsequently, the method or control means returns 8th back to step S10.

Accordingly, a user can operate by operating the actuating means 9 and then pivoting the seat back 3 until this at most the predetermined release angle E with the seat bottom 1 includes, with low (ren) operating forces the braking device 4 solve and thus use an EasyEntry functionality.

By pivoting back the seat back 3 until the contact sensor 7 recorded that the angle between seat back 3 and seat base 1 (Again) is greater than the predetermined release angle or at least equal to the predetermined closing angle, the user can close the brake device again.

In an alternative embodiment, a locking device in the braking device 4 integrated, which, for example, by ball-writing known per se, has two stable locking positions, wherein in a locking position, the braking device 4 is stationary dissolved or remains permanently or without (renewed) actuation remains, and is stationary in the other locking position or permanently closed or without (renewed) actuation.

In the alternative embodiment, the control means 8th a method, which in 4 is shown.

In this it also checks in step S10 whether by the actuating means 9 the lock 10 was solved.

If this is the case (S10: "Y"), is also switched to an active operating mode in which the control means 8th proceeds to step S20. Otherwise, the method or control means repeats 8th also step S10.

In step S20 is also by means of contact sensor 7 detects if the seat back 3 Having a predetermined release position by checking whether the angle that they with the seat bottom 1 includes, less than or equal to a predetermined release angle E or not. This is smaller than a front comfort angle, the adjustment range F to the seat bottom 1 limited.

If this is the case (S20: "Y"), it checks in a step S25 whether a status (identifier) of the brake device 4 "closed is.

If this is the case (S25: "Y"), the control means is energized 8th in a step S30 temporarily for a predetermined operating time of a few milliseconds the actuator 5 and then returns to step S20. This thus transfers the latching device into the latching position in which it is or remains stationary. Then a user can the seat bottom 1 on the rails 2 move to facilitate access to a rear area behind the seat back 3 to create, as in 2 shown. In addition, in step S30, the status (identifier) of the detent device is switched to "open".

Otherwise (S25: "N"), the method or control means returns 8th back to step S20.

If that through the contact sensor 7 detected angle that the seat back 3 with the seat bottom 1 includes, not (more) less than or equal to the predetermined release angle E and vice versa greater than or equal to a predetermined closing angle is (S20: "N"), provides the control means 8th firmly that the seat back 3 has a predetermined closed position.

Then the control means is energized 8th in a step S40 temporarily for a predetermined operating time of a few milliseconds the actuator 5 , This thus transfers the latching device into the latching position in which it is or remains stationary. Accordingly, in step S40, the status (identifier) of the detent device is switched to "closed".

Subsequently, the method or control means returns 8th back to step S10.

Accordingly, a user can also in the alternative embodiment by operating the actuating means 9 and then pivoting the seat back 3 until this at most the predetermined release angle E with the seat bottom 1 includes, with low (ren) operating forces the braking device 4 solve and thus use an EasyEntry functionality.

By pivoting back the seat back 3 , until contact sensor 7 recorded that the angle between seat back 3 and seat base 1 (Again) is greater than the predetermined release angle or at least equal to the predetermined closing angle, the user can close the brake device again.

The contact sensor 7 detects whether the angle, the seat back 3 and seat base 1 include each other, less than or equal to the predetermined release angle or vice versa greater than or equal to the predetermined closing angle, and thus two-stage, the position of the seat back 3 , in particular, whether it has a release position (S20: "Y") or not (S20: "N") or whether the seat back 3 a closed position complementary thereto (S20: "N") or not (S20: "Y").

Although exemplary embodiments have been explained in the foregoing description, it should be understood that a variety of modifications are possible. It should also be noted that the exemplary embodiments are merely examples that are not intended to limit the scope, applications and construction in any way. Rather, the expert is given by the preceding description, a guide for the implementation of at least one exemplary embodiment, with various changes, in particular with regard to the function and arrangement of the components described, can be made without departing from the scope, as it turns out according to the claims and these equivalent combinations of features.
