How do ISOFix and top-fix installation systems work?
1. ISOFix system
How it works
Fixed connection points: The ISOFix system uses two metal connection points (ISOFix anchor points) under the car seat, which are located in the gap between the seats. There are special connection hooks on the ZK701A Child Safety Seat Isofix 360 Degree Group 0123, which can be directly inserted into the anchor points for a secure fixation.
Simplified installation process: Compared with the traditional seat belt installation method, the ISOFix installation process is simpler. Parents only need to insert the seat's connection hook into the anchor point, and confirm the installation is successful when they hear a "click" sound or see the indicator light on, without additional adjustment or tightening the seat belt.
Reduce installation errors: Because ISOFix does not rely on seat belts, it reduces safety hazards caused by improper installation. Incorrect installation methods may cause the seat to fail to provide the protection it should provide in a collision.
Advantages
Higher safety: The ISOFix system can effectively reduce the displacement of the seat in an accident and provide higher safety by directly connecting to the vehicle structure.
Strong stability: In the event of a collision, the seat is tightly connected to the vehicle through the fixed points, reducing the forward tilt or movement caused by inertia.
Strong adaptability: Most modern cars are equipped with ISOFix anchor points, which are highly compatible.
2. Top Tether System
How it works
Additional fixing strap: The top fixing system has a strap on the back of the child seat, and the other end is connected to a dedicated fixing point at the rear of the car (usually located on the back wall or roof of the back seat). This strap provides additional support for the seat.
Limit forward tilt: In the event of a collision, the top fixing strap can effectively limit the forward movement of the seat, reducing the risk of injury to the child caused by the collision.
Advantages
Enhanced stability: When used in combination with ISOFix, the top fixing system provides a three-point fixation, which effectively increases the stability of the seat and further improves safety.
Reduced tilt: The system is specially designed to prevent the seat from tilting too much in a collision, so that the impact on the child in the accident is reduced.
3. Safety standards
Compliance with international standards: Both ISOFix and the top fixing system have been rigorously tested and meet European and international safety standards (such as ECE R44/04). These standards require that the seat can effectively protect the child in a collision.
Industry certification: Many seats are crash-tested by specialized agencies before they are launched on the market to ensure that they meet safety requirements.
4. User-friendly design
Visual feedback: Many ISOFix systems are equipped with indicator lights or sound prompts to help parents confirm whether the seat is installed correctly. This design reduces parents' concerns and makes the installation process more intuitive.
Versatility: Some seat designs allow easy switching between different installation methods, making them adaptable to different car models and children's growth needs.
