Valve device for airbag utilized in passenger compartment of passenger car to protect occupant during accident, has air-permeable film formed with airflow openings that are partially overlapped with air-permeable support structure and film

摘要

#CMT# #/CMT# The device has an air-permeable support structure in an air flow direction. An air-permeable film is partially overlapped with the support structure and indirectly connected with the support structure. The film is formed with airflow openings that are partially overlapped with the support structure and the film, and is indirectly connected with the support structure and the film. The support structure and the film are made of fabric. The film is arranged between two textile materials, where one of the textile materials comprises a recess corresponding to the openings. #CMT# : #/CMT# An independent claim is also included for an airbag for a motor vehicle. #CMT#USE : #/CMT# Valve device for an airbag that is utilized in a passenger compartment of a motor vehicle (all claimed) i.e. passenger car, to protect an occupant during an accident. #CMT#ADVANTAGE : #/CMT# The air-permeable support structure and the air-permeable film enable desired flow of medium in a retention volume of the airbag, so that the retention volume of the airbag is rapidly filled with ambient air at a short period, thus changing the airbag from a storage position into a retention position in a quick manner. The device has high robustness with respect to loads acting on the device, thus preventing damage of the device.
