Description

Technical Field

[0001] The utility model relates to the technical field of safety belt installation components, in particular to a stamping fixing piece of a latch force unloading device. Background Art

[0002] Automobile seatbelt systems include a latch-loaded force-reducing device, which is part of the seatbelt. Its primary function is to instantly tighten the pretensioner in the event of a collision or emergency braking, tightening any slack and securing the occupant to the seat to prevent a secondary collision. When the belt's tightening force exceeds a certain limit, a force-limiting device releases the belt appropriately, maintaining a stable force on the chest and protecting the occupant. This force-limiting device ensures the belt protects the occupant while preventing injury from overtightening.

[0003] Seatbelt latches are typically used in conjunction with seatbelt pretensioners and are mounted on the vehicle body using stamped fasteners. Existing stamped fasteners only have a single hole for installation and fixation, resulting in poor installation stability and potentially compromising the safety of the seatbelt system.
