Abstract

Device and Method for Contactless Magnetic field guided adaptable and reconfigurable aircraft seating

The objective of the present invention is a Device and Method for Contactless Magnetic Field Guided automated adaptable and reconfigurable aircraft seating. This will enable an aircraft cabin with automated layout change.

The advantages of the invention are: - Automated cabin seat adjustment, - Automated cabin layout reconfiguration - Automated adaptation of seat pitch - Reduction of costs - Reduction of assembly time for cabin seat installation.

Device and Method for Contactless Magnetic field guided adaptable and reconfigurable aircraft seating

Today the aircraft seating uses seat rails. A cabin layout is more or less permanent after installation. And a reconfiguration of a cabin seating layout can only be realized manually.

The cabin layout and seat pitch in x- and y-direction is fixed. This limits the passenger comfort and the flexibility of the airlines to react on changing needs of the passengers. Aircraft Cabin Seats are mounted on seat rails, using seat fittings. See Fig. 1.

Figure 2 describes right a typical seat rail and left a typical seat locking device (stud), each of which has to be unlocked by a tool upon which a manual relocation of the seat takes place, and then the stud needs to be fastened again with the tool.

EP0282244 describes an adjusting seating arrangement for an aircraft. The moving seat and automated adaptable cabin layout is described using a mechanical device:

The objective of the present invention is a Device and Method for Contactless Magnetic Field Guided automated adaptable and reconfigurable aircraft seating. This will enable an aircraft cabin with automated layout change:

The advantages of the invention are:
- Automated cabin seat adjustment,

- Automated cabin layout reconfiguration

- Automated adaptation of seat pitch

- Reduction of costs

- Reduction of assembly time for cabin seat installation.

On different routes of the aircraft different cabin layouts can be instantly realized and the seat pitch can easily be adapted according to the needs of an airline.

Example for a seat reconfiguration in X direction (by extension of concept also in Y-direction).
- Installation of a flexible cabin seating with automatic (electric/electronic) seat positioning (e.g. in X & Y-direction) before PAX are boarding.

- Possibilities to particularly consider leg space needed by tall passengers, alternatively adequate room for physically impaired PAX.

The present invention works in a way that magnetically supported movement and transport of passenger seats enables an automated cabin layout change.

Conventional seat rails and locking devices are replaced by new seat rails as shown in the following figures.

Fig. 5. Seat rail

A magnetic seat fixation device (Fig. 4), which is placed inside of a hollow seat rail (Fig. 5), is attached to a superconducting material (Fig. 6). The superconducting material is contactless guided through the hollow seat rail by moving an external magnetic field generator (linear motion; linear motor) (Fig. 4).

This cab e.g. be a permanent magnet, an electromagnetic device or preferably a super conducting element.
