Global automotive seating leader Adient showcased a multi-material lightweight seat structure, made from die-cast magnesium, at the 2018 North American International Auto Show (NAIAS).
Lightweighting--reducing overall vehicle weight to increase aerodynamics, performance and fuel efficiency, and to lower fossil fuel emissions--is a guiding dynamic in the auto industry. Lightweight applications include a range of vehicle components and basic operating equipment including forged magnesium wheels, body panels and interior elements like dashboards and seats.
"Magnesium is the lightest of all structural materials--75 percent lighter than steel and 33 percent lighter than aluminum," said Dr. Detlef Juerss, Vice President Engineering and CTO at Adient. "Because of this, the Adient seat structure has a very good strength-to-weight ratio, flexible construction possibilities and very good dimensional stability."
Adient supplies vehicle seats to every major global automaker. The past 10 years have seen the company reduce the weight of its vehicle seats by 20 to 30 percent. The company has set a goal to reduce the weight of standard seat structures by 22 pounds by 2020, through a multi-material approach, optimizing the use of lightweight materials including magnesium, carbon fiber-reinforced plastics, high-strength steel or aluminum.
“Car seats will increasingly become multi-function supports with a wide range of electronic adjustments and technical equipment,” said Dr. Juerss. “Our engineers are working to combine these innovations with weight reduction--and, of course, these seats must meet our highest safety and quality standards.”
The annual North American International Auto Show, held in Detroit, Michigan, is among the largest auto shows in North America.
