Core Functions

• Passenger Restraint: During collisions or sudden deceleration, the retractor’s emergency locking mechanism (ELR) activates in milliseconds—locking the webbing to prevent the passenger from moving forward. This distributes impact forces across the chest, hips, and shoulders (the body’s strongest areas), reducing the risk of chest, head, or spinal injuries.
• Controlled Force Absorption: The webbing’s woven polyester construction stretches slightly during high-impact events (a design called “energy management”). This controlled stretch reduces the peak force exerted on the passenger by up to 30%, minimizing injury severity while still preventing excessive forward movement.
• Secure Fastening: The buckle and tongue feature a precision-engineered latching system that stays securely closed during normal use but can be released quickly in emergencies. The buckle also includes a “seat belt reminder” sensor (where applicable) that alerts the driver if the rear right passenger has not fastened their belt—encouraging compliance with safety protocols.
• Daily Convenience: The retractor’s “automatic locking retractor” (ALR) mode (on select variants) locks the webbing in place when fully extended—ideal for securing child safety seats. In normal use, the retractor allows the webbing to move freely with the passenger (e.g., adjusting seating position) for comfort.
