BMW significantly reduced back seats weight using ARPRO®
A design team from BMW, working with engineers from JSP and other specialists, has achieved weight savings of 15 per cent and cost savings of 10 per cent in the construction of rear seat-backs for the BMW 5 Series
The design project began in 2005 and series development of the new Sandwich Seatback started in July 2007. The team’s idea was to use an innovative three-part structure to create a lighter seatback, capable of passing statutory impact tests and BMW’s own test schedule: at its centre is a section of energy-absorbing ARPRO BMW calculate that the weight saving totals 1.2 kg on an already ‘weight-reduced’ component. Other benefits include a reduced number of components, the elimination of numerous process steps, and improved recyclability. Paul Compton, JSP President and Chief Executive Officer - Europe said that this highly-successful design project was an excellent illustration of ARPRO’s ability to help automotive designers push traditional boundaries: ‘Our business approach at JSP is working with designers to exploit ARPRO’s extraordinary versatility. With BMW’s Sandwich Seatback the result is a win on all fronts – economics, manufacturing efficiency, environmental benefits and – not least – passenger safety and functionality.’ ARPRO is an Expanded Polypropylene (EPP) used extensively for automotive parts as well as for packaging and other applications requiring great lightness and strength. ARPRO is 100 per cent recyclable.
