摘要

#CMT# #/CMT# The device (10) has an inflation unit (12) connected to an airbag (11) via a feed pipe (13) for feeding inflation fluid to inflate the airbag under predetermined conditions. A fluid expulsion unit (20) e.g. solenoid valve, is co-operated with a detection unit (15) for detecting a predetermined event to remove the fluid resulting from inflation of the airbag when the event occurs to inflation of the airbag. The airbag is provided with a peripheral elastic strap for optimizing the deflation of the airbag when the expulsion unit allows the fluid to be removed from the airbag. #CMT# : #/CMT# The event is a water presence event, a fire presence event, and a seat belt opening event subsequent to inflation of the airbag. An independent claim is also included for a vehicle seat comprising a bottom zone and a back zone. #CMT#USE : #/CMT# Device for protecting an occupant in a seat of a vehicle (all claimed) e.g. aircraft such as rotary-wing aircraft. #CMT#ADVANTAGE : #/CMT# The airbag is provided with the peripheral elastic strap for optimizing deflation of the airbag when the expulsion unit allows the fluid to be removed from the airbag, thus allowing the device to effectively protect the occupant in the seat of the vehicle even in the event of contact with the aqueous surface while removing the risk of unduly trapping the occupant in the vehicle in the event in which the water enters the vehicle. The elastic strap does not hinder inflation of the airbag during evacuation of the occupant from the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic front view of an occupant protecting device. 10 : Occupant protecting device 11 : Airbag 12 : Inflation unit 13 : Feed pipe 15 : Detection unit 20 : Fluid expulsion unit.
