QUADRANT CMS DEVELOPS MULTIPLE AIRBAG HOUSINGS FOR NEW CITROEN C5

TIELT, BELGIUM – February 2008 – Quadrant Creative Moulding & Systems (Quadrant CMS) of Tielt, Belgium, working in close co-operation with Tier-1 automotive supplier TRW - Dalphimetal of Madrid, Spain, has developed all three front airbag housings for the new Citroën C5. The housings for the driver airbag, passenger airbag and knee airbag are moulded in impact-modified Akulon® Polyamide 6 from DSM with 40 percent glass-fibre reinforcement.

All three housings were specifically developed, engineered and optimized for the Citroën C5 by Quadrant CMS in close collaboration with TRW. The experience of Quadrant CMS in both the design and production of such parts helped to significantly shorten the time to market. Initial testing of the design was done on parts produced in prototype moulds, including dynamical, mould flow and warpage analysis carried out with DSM as the material supplier.

“Quadrant CMS has more than ten years of experience in the development and production of airbag housings,” says Alessandro Varesi, Project Buyer of TRW-Dalphimetal. “This was one of the main reasons for us to choose to work with them on the development of the front airbags for the new C5. Although polymers are used more often for the manufacture of airbag housings – thus providing weight saving and lower cost-of-manufacture – their design varies according to the specific model and the location of the housing. It is an area where Quadrant CMS’ knowledge and experience in the development and production of systems critical polymer parts and components for safety systems come to the fore.”

“The deployment behaviour of the bag is very much depending from the design of the cockpit,” explains Wim Vlaeminck, Project Development Engineer at Quadrant CMS. “For instance, the inclination of the windshield influences the direction in which the bag unfolds.” Further considerations for the housing’s design and development include the extreme conditions under which airbags are required to function. Beyond the aggressive loads that the housing has to endure on deployment, it must also be able to guarantee failsafe operation over a wide temperature range.

The new Citroën C5 was unveiled in October 2007 with a host of safety features. It is the first Citroën to be equipped with a collapsible pedal assembly - in the event of an impact the brake and clutch pedals retract into the floor of the foot well to limit injury to the driver's legs and feet. The new C5 further introduces the second-generation fixed-centre steering wheel, with membrane-covered controls, providing easy access to key functions such as the cruise control, radio or telephone. A lane departure warning system (LDWS) is available on some versions and up to nine airbags, including the knee airbag, can be fitted.
