When it comes to protecting people's lives, we don't only produce components. We also produce confidence. With seat belt springs of impressively high quality and durability.
Safety is no longer just a feeling.
It's a certainty.
Products are something you can try to copy. Experience isn't. KERN-LIEBERS Strip Springs not only helped to develop the first seat belt springs, it has also manufactured more than 5 billion of them to date. But beyond our profound knowledge, we also offer you something more: international availability of all components in accordance with uniform German standards. That makes us a reliable worldwide partner for outstanding quality.
You can rarely achieve anything extraordinary with ordinary means. That's why KERN-LIEBERS Strip Springs has its own special purpose machines – and unique development expertise: We design not only the ideal production process, but also the ideal product for you. In combination with our wide range of spring technologies, that's how we ensure the extremely high reliability of our seat belt springs.
Genuine safety is only possible when errors don't happen. That's why with us, every single step in the manufacturing process is strictly monitored and meticulously documented – from goods receipt through development and production to shipping. Our outstanding quality management system is acknowledged not only by numerous certifications, but also by our top customers: 98 percent of them give us an A rating.
Even the best material is only as good as the way it is processed. It's only the extensive expertise of KERN-LIEBERS Strip Springs that turns high-quality materials into first-class seat belt springs. We combine our decades of experience with the very latest technologies to ensure the outstanding durability of our products at all times.
If you want to get ahead, sometimes you have to get back to basics. With Primaflex, we reinvented the raw material for our seat belt springs: the steel strip. Working together with a partner company, KERN-LIEBERS Strip Springs developed a texture-rolled special steel that's particularly robust and durable. That not only makes Primaflex an innovative material – it also contributes to even higher levels of safety.
