Mercedes-Benz Unveils New Active Seat-Belt Buckle

Follow Viknesh

Continuing its tradition of pioneering new safety technology, Mercedes-Benz has unveiled a new active seat-belt buckle for the rear seats that’s set to enter production later this year.

The buckle features an electric motor that allows it to extend out from the seat or retract into it.

In this way, the belt slack in the area of the pelvis and thorax can be reduced during the event of a crash, with passengers being secured more firmly in sideways and lengthways directions.

The active seat-belt buckle is integrated in Mercedes’ PRE-SAFE preventive safety system. This means that whenever PRE-SAFE becomes active in critical driving situations or when a critical distance from other objects is detected, reversible belt tensioning can be effected in the rear via the active seat-belt buckle function.

The restraint system and the passengers are thus better prepared for a possible accident situation. However, the system also has the added benefit of making seat belt fastening in the rear much simpler: the seat belt buckle emerges from the upholstery when the rear doors are opened and is provided with an illuminated insertion slot.

The new active seat-belt buckle will eventually replace the pyrotechnic belt tensioning system which has featured as standard in Mercedes-Benz vehicles for several years now.
