Left Side 3-Point Seat Belt Assembly for BYD Dolphin Vehicle with Seat Belt pre-tensioner

The Left Side 3-Point Seat Belt Assembly with Pre-tensioner is a critical safety component engineered specifically for the BYD Dolphin electric vehicle. Designed to meet stringent automotive safety standards, this seat belt system features a pyrotechnic pre-tensioner mechanism that instantly removes slack during collisions, working in tandem with the vehicle's airbags to optimize occupant protection. The robust construction ensures reliability under extreme conditions, aligning with BYD Dolphin's commitment to passenger safety.

• Pre-tensioner Mechanism: In a collision, the pre-tensioner ignites gas in a chamber, driving a piston to retract the belt within milliseconds. This forces the occupant into an optimal crash position, reducing injury risks. Functions alongside conventional locking mechanisms to prevent belt extension during sudden deceleration.
• Durability & Comfort: The polyester webbing withstands tensile strengths exceeding 23 kN, ensuring resilience under stress. Smooth retraction and adjustable fit enhance comfort for daily use.
• Vehicle-Specific Design: Tailored for the BYD Dolphin's interior dimensions, ensuring seamless integration with the left-side anchor points.

• Installation: Must be performed by certified technicians to ensure proper alignment with the vehicle's safety system. Post-installation functional tests are mandatory.
• Maintenance: Clean only with warm soapy water; avoid chemicals or bleach. Replace the entire assembly after any collision, as the pre-tensioner is single-use. Inspect every 2 years or 40,000 km for wear, fraying, or corrosion.

• Do not attempt to disassemble or modify the pre-tensioner—risk of accidental activation
• Ensure no children are restrained using a single belt assembly
• Verify compatibility with the specific BYD Dolphin model year before purchase
