Description

A retractable and anti-flipping car safety seat base

[Technical field]

The invention relates to a baby car safety seat, in particular to a retractable and anti-turnover car safety seat base.

[Background technology]

With the improvement of living standards, the number of family cars is also increasing. Choosing a car for travel has become a common way for families to travel daily. Equipping the car seat with a car safety seat that can be used by children of all ages can effectively improve the safety of children in the car. At present, most child car safety seats are composed of a seat that can be sat on and a base installed on the bottom of the seat on the car seat. The installation of the base and the car seat mainly adopts the ISOFIX interface, that is, the ISOFIX interface set on the base is connected to the preset interface on the car seat, and the interface is docked and locked, which is simple and quick to install.

However, since car safety seats come in different styles and are designed in different sizes, some ISOFIX interfaces that cannot be telescopically adjusted cannot be adapted to car seats of different sizes, resulting in low practicality and low market competitiveness.

Other retractable ISOFIX interfaces can be suitable for car seats of different sizes, that is, by extending the length of the sliding sleeve of the ISOFIX interface, the ISOFIX interface force arm becomes longer. At the same time, the rear part of the base cannot be against the car seat backrest, resulting in it being unable to meet the installation, fitting and anti-rollover requirements of car seats of different sizes, posing certain safety hazards.

Therefore, the present invention is studied and proposed in view of the above-mentioned problems.
