## Abstract

A passenger protection module for use inside an aircraft or other commercial carrier, the passenger protection module comprising an enclosure releasably installed inside an aircraft, at least one passenger seat installed inside the enclosure, a doorway providing passenger ingress into and egress from the enclosure, and a supply of treated and purified air flowing through the enclosure at a positive pressure relative to air outside the enclosure.

## Claims

### Claim 1

A passenger protection system comprising a plurality of selectively moveable and relocatable passenger modules each configured to seat one or more passengers in a contained, positive-pressure environment during flight of an aircraft.

### Claim 2 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module is configured to seat from one to four passengers.

### Claim 3 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module further comprises a door and a doorway allowing passenger ingress into and egress from the module.

### Claim 4 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module comprises means to facilitate food and beverage service to each passenger inside the passenger module.

### Claim 5 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module operably communicates with a continuous source of filtered, treated and pressurized air.

### Claim 6 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module is releasably attached to the aircraft.

### Claim 7 (depends on 7)

The passenger protection system of claim 7 wherein each passenger module comprises at least one passenger seat releasably attached directly to the aircraft.

### Claim 8 (depends on 7)

The passenger protection system of claim 7 wherein each passenger module comprises at least one passenger seat that is releasably attachable to the passenger module.

### Claim 9 (depends on 1)

The passenger protection system of claim 1 wherein each passenger module comprises a plurality of wall sections.

### Claim 10 (depends on 5)

The passenger protection system of claim 5 wherein each passenger module is configured to continually receive and discharge a supply of air sufficient to maintain a positive pressure inside each passenger module relative to the air pressure inside the aircraft but outside the passenger module.

### Claim 11

A passenger protection module for use inside an aircraft, the passenger protection module comprising an enclosure releasably installed inside an aircraft, at least one passenger seat installed inside the enclosure, a doorway providing passenger ingress into and egress from the enclosure, and a supply of treated and purified air maintained inside the enclosure at a positive pressure relative to air outside the enclosure.

### Claim 12

A passenger protection module for use inside an aircraft or other commercial carrier, the passenger protection module comprising an enclosure releasably installed inside an aircraft, at least one passenger seat installed inside the enclosure, a doorway providing passenger ingress into and egress from the enclosure, and a supply of treated and purified air flowing through the enclosure at a positive pressure relative to air outside the enclosure.
