Abstract
An emergency evacuation system includes a first floatation device, an inflator operably coupled to the first floatation device, and a second floatation device coupled to the first floatation device. The inflator is configured to inflate the first floatation device to deploy the emergency evacuation system outside of a compartment, such as proximate to a door of a vehicle.
Claims26
An emergency evacuation system comprising:
- a first floatation device;
- an inflator operably coupled to the first floatation device;
- and
- a second floatation device coupled to the first floatation device,
- wherein the inflator is configured to inflate the first floatation device to deploy the emergency evacuation system outside of a compartment, and
- wherein the first floatation device in an inflated state is configured to dispose an open inflation system above water.
