## Abstract

A method for tilting a seat of a vehicle based on a first threshold (low) and a first threshold (high) for a first parameter of the vehicle and a second threshold (low) and a second threshold (high) for a second parameter of the vehicle. The tilt angle of the seat is increased if the first parameter is greater that or equal to the first threshold (low) and the second parameter is greater than or equal to the second threshold (high) or if the parameter is greater than or equal to the first threshold (high) and the second parameter is greater than or equal to the second threshold (low).

## Claims

### Claim 1

A method for adjusting a tilt angle of a seat of a vehicle, comprising:
sensing a first parameter of the vehicle;
sensing a second parameter of the vehicle;
retrieving a first thresholdlow for the first parameter, a first thresholdhigh for the first parameter, a second thresholdlow for the second parameter, and a second thresholdhigh for the second parameter, wherein the first thresholdlow is less than the first thresholdhigh and wherein the second thresholdlow is less than the second thresholdhigh; and
increasing the tilt angle of the seat if the first parameter is greater than or equal to the first thresholdlow and the second parameter is greater than or equal to the second thresholdhigh or if the first parameter is greater than or equal to the first thresholdhigh and the second parameter parameter is greater than or equal to the second thresholdlow.

### Claim 2 (depends on 1)

The method of claim 1 further comprising maintaining the tilt angle of the seat if first thresholdlow is less than or equal to the first parameter first thresholdhigh and second thresholdlow is less than or equal to the second parameter is less than the second thresholdhigh.

### Claim 3 (depends on 2)

The method of claim 2 wherein said sensing a first parameter includes sensing a steering angle of a steering device of the vehicle.

### Claim 4 (depends on 3)

The method of claim 3 wherein said sensing a second parameter includes sensing a speed of the vehicle.

### Claim 5 (depends on 2)

The method of claim 2 wherein said sensing a first parameter includes sensing a lateral acceleration of the vehicle.

### Claim 6 (depends on 5)

The method of claim 5 wherein said sensing a second parameter includes sensing a yaw rate of the vehicle.

### Claim 7

A method for adjusting a tilt angle of a seat of a vehicle, comprising:
sensing a first parameter of the vehicle;
sensing a second parameter of the vehicle;
retrieving a first thresholdlow for the first parameter, a first thresholdhigh for the first parameter, a second thresholdlow for the second parameter, and a second thresholdhigh for the second parameter, wherein the first thresholdlow is less than the first thresholdhigh and wherein the second thresholdlow is less than the second thresholdhigh,
increasing the tilt angle of the seat if the first parameter is greater than or equal to the first thresholdlow and the second parameter is greater than or equal to the second thresholdhigh or if the first parameter is greater than or equal to the first thresholdhigh and the second parameter is greater than or equal to the second thresholdlow; and
retrieving a first thresholdmed for the first parameter and a second thresholdmed for the second parameter, wherein the first thresholdlow is less than the first thresholdmed is less than the first thresholdhigh and wherein the second thresholdlow is less than the second thresholdmed is less than the second thresholdhigh.

### Claim 8 (depends on 7)

The method of claim 7 further comprising increasing the tilt angle of the seat if the first parameter is greater than or equal to the first thresholdmed and the second parameter is greater than or equal to the second thresholdmed.

### Claim 9 (depends on 8)

The method of claim 8 wherein said sensing a first parameter includes sensing a steering angle of a steering device of the vehicle.

### Claim 10 (depends on 9)

The method of claim 9 wherein said sensing a second parameter includes sensing a speed of the vehicle.

### Claim 11 (depends on 8)

The method of claim 8 wherein said sensing a first parameter includes sensing a lateral acceleration of the vehicle.

### Claim 12 (depends on 11)

The method of claim 11 wherein said sensing a second parameter includes sensing a yaw rate of the vehicle.

### Claim 13 (depends on 1)

The method of claim 1 wherein said retrieving includes retrieving from a memory device.

### Claim 14 (depends on 1)

The method of claim 1 wherein said retrieving includes retrieving from an occupant of the vehicle.
