Description
Technical Field
The invention relates to the field of child safety seats, in particular to a vehicle safety seat capable of being turned and folded.
Background
The existing children safety seats with ISOFIX interfaces are all connected with backrests from bases through ISOFIX metal interfaces, and the tests of 1 group (9-18 KG) of P3 dummy must pass misuse tests (namely, a pull belt cannot be used) according to the requirements of European Union standard ECE R44/04 and national standard GB 27887; therefore, the force for bearing the collision impact of the whole seat only by two interfaces of the base ISOFIX is very huge, and the collision impact can only pass through the whole metal bracket of the seat and can pass through standard detection, so that the production cost is increased.
Moreover, most of the conventional ISOFIX child safety seats are fixed, and the backrest, the base and other parts are fixed in position and cannot be folded, so that the overall size of the child safety seat is large, and the child safety seat is difficult to transport and carry; in a few foldable seats, a plurality of components such as a headrest, a backrest, armrests, a seat cushion and the like are detachably connected with one another, but the impact resistance of the seats is inevitably reduced, and in order to overcome the problem, a metal component support is adopted in the majority of seats, so that although a certain impact resistance can be improved, the connection part of the components is still easy to break when bearing impact force, and the safety is low.
In summary, in order to provide a seat that can be folded to reduce the overall size of the seat and at the same time has sufficient stability to enable the seat to pass standard detection, the applicant proposes a foldable car safety seat.
