Abstract

Disclosed are methods for arranging passenger seats and passenger service units in aircraft cabins as well as locating devices used in these methods. These methods and devices provide fast and efficient ways for directly referencing the position of each passenger service unit relative to a corresponding passenger seat. For example, a passenger seat is positioned on a seat rail using rail markers. Each set of markers corresponds to a different seating configuration. A locating device is then placed on the passenger seat such that the device datum contacts the seat cushion. A locator of the locating device determines a reference, in an overhead compartment, for installing a passenger service unit, corresponding to this seat. The reference is based on an angle between the datum and the locator, which is adjustable in some examples.

First claim

What is claimed is:

1. A method for arranging a set of passenger seats, comprising a passenger seat, and a set of passenger service units, comprising a passenger service unit; in an aircraft cabin; comprising a seat rail, the method comprising:
aligning a support fitting of the passenger seat with a first receiver of a receiver set on the seat rail,
wherein the seat rail comprises a first marker set, each identifying one receiver in the receiver set such that any two adjacent markers in the first marker set are spaced apart by a first seat pitch, and
wherein the first receiver is identified by a first marker of the first marker set;

positioning a locating device on the passenger seat such that a device reference point of the locating device coincides with a seat cushion reference point of the passenger seat and such that a device datum of the locating device is positioned on and in contact with a seat cushion of the passenger seat; and
using a front locator of the locating device, determining a first front reference in an overhead compartment for installing the passenger service unit, corresponding to the passenger seat,
wherein the first front reference depends on a first angle between the device datum and the front locator, and
wherein the first angle is selected based on a distance between the device datum and the passenger service unit and further based on the first seat pitch.

2. The method of claim 1 , wherein an angle between the device datum and the front locator is adjustable.

3. The method of claim 2 , further comprising adjusting the angle between the device datum and the front locator.

4. The method of claim 1 , further comprising determining the first angle at least based on the distance between the device datum and the passenger service unit and further based on the first seat pitch.

5. The method of claim 1 , wherein the first angle between the device datum and the front locator is further selected based on a height of a back rest of the passenger seat and a recline angle of the back rest.

6. The method of claim 1 , wherein the front locator comprises one of a laser pointer or an extendable arm.

7. The method of claim 1 , further comprising, using a rear locator of the locating device, determining a first rear reference in the overhead compartment for positioning the passenger service unit, wherein the passenger service unit is positioned between the first front reference and the first rear reference.

8. The method of claim 7 , wherein an angle between the device datum and the rear locator is fixed.

9. The method of claim 8 , wherein the angle between the device datum and the rear locator is determined based on a type of the passenger seat.

10. The method of claim 7 , wherein the rear locator is positioned against a back rest of the passenger seat while the device reference point of the locating device coincides with the seat cushion reference point and the device datum is positioned against the seat cushion of the passenger seat.

11. The method of claim 1 , further comprising, installing the passenger service unit in the overhead compartment at least in accordance with the first front reference.

12. The method of claim 11 , wherein a front edge of the passenger service unit is aligned with the first front reference.

13. The method of claim 11 , further comprising installing one or more filler panels, such that the one or more filler panels are positioned between the passenger service unit and a second passenger service unit, adjacent to the passenger service unit.

14. The method of claim 13 , wherein the first front reference comprises two reference points, separated by a reference distance.

15. The method of claim 14 , wherein the reference distance is greater than a width of a narrow-most filler panel of the one or more filler panels.

16. The method of claim 15 , wherein at least two of the one or more filler panels have different widths.

17. The method of claim 1 , wherein the seat rail comprises a second marker set, each identifying one receiver in the receiver set such that any two adjacent markers in the second marker set are spaced apart by a second seat pitch, different from the first seat pitch.

18. The method of claim 17 , further comprising:
aligning the support fitting of the passenger seat with a second receiver of the receiver set on the seat rail,
wherein the second receiver is identified by a second marker of the second marker set;

positioning the locating device on the passenger seat such that the device reference point of the locating device coincides with the seat cushion reference point of the passenger seat and such that the device datum of the locating device ( 170 is positioned on and in contact with the seat cushion of the passenger seat; and
using the front locator of the locating device, determining a second front reference in the overhead compartment for installing the passenger service unit, corresponding to the passenger seat,
wherein the second front reference is determined by a second angle between the device datum and the front locator,
wherein the second angle is selected based on a distance between the device datum and the passenger service unit and further based on the second seat pitch.

19. The method of claim 18 , wherein the second angle is different from the first angle.

20. The method of claim 19 , further comprising, installing the passenger service unit in the overhead compartment at least in accordance with the second front reference.
