4 PCS Car Seat Belt Clips Adjuster Universal Seatbelt Clip Positioner Strap Buckle, Shoulder Neck Positioner, Adjustable Holder, for Adult to Relax Neck,Black

【Universal Fit: Precise Capture of Standard Seat Belt Width】The package contains 4 seatbelt positioner clips, a quantity sufficient to meet the front and rear seat needs of cars, SUVs, and chartered vehicles. The slot width is specially designed to accommodate standard seat belts up to 53mm wide. This specification provides seamless limit control for standard webbing, restricting its automatic retraction, and is widely applicable to seat belt modifications and daily passenger protection in various vehicle types such as private cars, rental cars, and travel charters. Dimensions: 67x33x12mm. 【Three Rows of Anti-Slip Teeth: Secure Clamping to Prevent Slipping】The internal structure of the seat belt clip positioner is designed with three parallel rows of close-fitting sharp teeth, which, combined with the back interlocking buckle, grip firmly onto the seat belt fabric surface once locked. This anti-slip structure provides strong positioning, ensuring that the seat belt clip remains fixed in the preset position even during high-speed driving, bumpy vibrations, or frequent passenger posture changes, saving you the hassle of frequent manual readjustments. 【Free Tension Adjustment: Relief of Chest/Abdomen Pressure and Neck Friction】 Through the clamping positioning of the clip, you can block the retracting tension of the reel and pull out an appropriate amount of slack, thereby freely controlling and fixing the length of the seat belt. This structure directly reduces the tight squeezing sensation on the chest, abdomen, and stomach, while preventing the edge of the webbing from cutting or chafing the neck skin of drivers and passengers during emergency braking. It also effectively reduces frequent friction between the webbing and premium clothing, enhancing the travel experience. 【High-Density ABS Material: Wear-Resistant and Resistant to Damage or Deformation】 The seat belt adjusters is made of high-quality ABS material, possessing outstanding compressive strength, wear resistance, and impact-resistant lifespan. Under high-temperature exposure inside vehicles in summer or severe cold in winter, the ABS material does not easily age, crack, or deform. The surface and edges of the clip utilize a smooth, burr-free finish, ensuring rigid supporting force during clamping while never wearing down or snagging car seat belts and delicate clothing fibres. 【Simple Pry-Open Buckle: Damage-Free, Tool-Free Rapid Installation and Removal】The seatbelt fasten clip utilizes a two-piece, tool-free interlocking buckle structure, requiring no welding, heating, or chemical adhesives. Users only need to use a flat, hard object like a coin to insert into the slot to easily pry open the buckle. After clipping onto the webbing and adjusting to the desired slack position, simply snap it closed and press tightly to complete locking. The damage-free installation and removal design makes it highly convenient to rapidly switch and transfer between different vehicles and different passengers (such as pregnant women and the elderly).
