0-1-2-3 group safety seat with ISOFIX interface
Technical Field
The utility model relates to a 0-1-2-3 group take safe seat of ISOFIX interface.
Background
The child safety seats are classified according to the weight of children, and according to national and European regulations, the child safety seats are grouped according to the weight of the children, and can be divided into the following five groups: group 0 (0-10 kg), group 0+ (0-13 kg), group 1 (9-18 kg), group 2 (15-25 kg), group 3 (22-36 kg), and the products on the market are combined, i.e. group 0-1 (0-18 kg), group 0-1-2 (0-25 kg), or group 1-2-3 (9 months-36 kg), group 0-1-2-3 (0-36 kg).
The child safety seat is mounted in three ways, the first way is directly mounted by a vehicle-mounted safety belt, the way is a universal mounting way, and any automobile with a three-point vehicle-mounted safety belt can be mounted. The second is the ISOFIX fixing mode of European standard, which requires an ISOFIX interface on the automobile. Because the installation is quick and accurate, the possibility of misoperation is reduced, and the installation mode becomes the mainstream installation mode in the future. The third is the mounting mode of LATCH of American standard, which is different from ISOFIX mode in that the LATCH adopts soft connection mode.
The combination of safety seats and mounting means currently on the market are as follows:

Groups 0-1-2-3 cover all age groups (about 0-12 years), are used for a long time, and only one child can buy one. The products with the installation mode of 0-1-2-3 groups and ISOFIX have obvious user value and market demand and very wide market prospect, but because of certain technical difficulty, the products do not exist in the current market and are blank spots in the market.
As the design of the safety seat must meet national and European standards, and the external dimension of the safety seat with the ISOFIX structure must meet the dimension requirement specified in B.3.4 in GB14166-2013, a plurality of constraint conditions are added. In addition, the group 0-1-2-3 + ISOFIX safety seats must simultaneously meet the following requirements:
1. the 0+ group seat body must be installed in reverse and the seat body angle must be reclined.
2. 1/2/3 sets of seat bodies must be installed in a forward direction.
In the existing product, the seat body and the ISOFIX interface are of an integrated structure with the ISOFIX interface of 0-1-2 groups, and cannot meet the size requirement specified by the standard, so that the seat body cannot extend to 3 groups; 1-2-3 groups of products with ISOFIX structures, which cannot be installed in reverse, do not have the function of the 0+ group. Group 0-1-2-3, there are no products with ISOFIX interfaces on the market today.
