Description

Adjustable ISOFIX interface system

technical field

The utility model relates to an automobile child safety seat, in particular to an adjustable ISOFIX interface system applied to the child safety seat.

Background technique

In recent years, with the rapid development of the automobile industry and automobile service industry, the number of family cars in my country has doubled, and my country's traffic laws and regulations have also been continuously improved. When a passenger car carries a child, the law requires that the child must sit in a child safety seat superior. A child safety seat is a seat specially designed for children of different weights (or age groups), restraining the child in the safety seat, and effectively improving the safety of the child in a car.

There are two ways to fix the traditional child safety seat. One is to fix the seat with a safety belt, and the safety belt is positioned with a hook in the dark groove of the rear seat of the car, and the child is restrained by the safety belt on the child seat. Chinese Patent Publication No. CN102951044A is exactly the child safety seat of this kind structure. The connection between this kind of child safety seat and the car is not stable, because the seat belt is buckled with the hook in the dark groove of the rear seat, only the upper part of the seat can be fixed, but the lower part of the seat is not well positioned. There is a gap between the seat belt and the hook in the recessed channel of the rear seat, which will cause the seat to shake. Therefore, the stability of this type of seat is not high.

Another way of fixing the child safety seat is through the ISOFIX device. The full name of ISOFIX is "International Standards Organization FIX", which means in Chinese: International Organization for Standardization Fixtures. The ISOFIX device is to fix the child safety seat on the rear seat of the car through the ISOFIX interface provided on the rear seat of the car and the safety seat which can cooperate with each other. Chinese Patent Publication No. CN101573252A is such a child safety seat fixed through an ISOFIX interface. The child safety seat fixed by the ISOFIX interface can achieve the purpose of fixing the lower part of the seat, and has high stability. And in the prior art, various adjustable structures have also appeared in this type of ISOFIX interface system, to adjust the length of the ISOFIX interface relative to the safety seat, to adapt to different vehicle models or different seat inclination angles, so that the seat back of the safety seat is in line with the safety seat. The backs of the rear seats of the car lean against each other to ensure the stability of the installation.

The above-mentioned CN101573252A is an adjustable ISOFIX interface system. This previous document discloses a device for operating the anchoring system of a car baby seat. As shown in Figure 1, the anchoring system includes a pair of With an integrated hook 2', the infant seat can be moved along said bar 3', said operating means comprising a pair of locking elements 4' which lock the movement of the infant seat relative to said bar 3' , the locking element 4' is movable between the locked position and the released position under the action of the elastic device 12', the locking element 4' is composed of a pawl meshing with a tooth 5' on the bar 3' . The pawl locking of the locking element is controlled by the elastic device and the teeth on the loosening bar realize the adjustment and fixing of the front and rear positions of the baby seat, and the baby seat is easy to install and adjust. But its shortcoming is: the releasing position of locking element 4 ' is realized by pressing a pair of button 9 ' that is arranged on both sides of the seat, must press 9 ' by both hands during operation, and the adjustment of seat front and rear position The seat must be pushed forward or backward artificially. In such an operation mode, when adjusting the front and rear positions of the seat, on the one hand, both hands need to press the buttons 9' on both sides at the same time, and on the other hand, the seat must be pushed or pulled hard. Very inconvenient. Moreover, the linkage structure between the buttons 9' on both sides and the locking element 4' is realized by two rods 11' and an intermediate body 8', and the buttons 9' and rods 11' on both sides drive the intermediate body 8' to move An unbalanced state is likely to occur, and one side of the locking element 4' is likely to be unlocked, but the other side cannot be unlocked, thus causing inconvenience in operation.
