When the Seat Becomes a Guardian Angel

The Anti-Whiplash Assembly is welded to the seat rail. An energy-absorbing element dampens vertical forces in the event of an impact to protect the occupants of the vehicle. So it should come as no surprise that this safety-critical assembly requires the greatest care and the full range of our production engineering skill. Four stamped parts, fine-blanked parts, and a follow-on composite component are used. These are hardened, brush-deburred, and laser-welded, among other things. This turns seven individual parts into a highly complex riveted assembly. Despite these demanding requirements, production is fully automated. A robot packs the assembly directly into the corresponding final packaging for the customer. The data-matrix code (DMC), the alpha-numeric code and the System Application Product (SAP) system ensure full traceability of the component.
