Backrest ventilation device and safety seat

Abstract

A backrest ventilation device and safety seat, relating to the field of safety seat technology. The backrest ventilation device provided by this disclosure includes: an air guide assembly and a cushion cover, with the air guide assembly installed on the cushion cover, which can be detachably connected to the backrest and/or headrest through the cushion cover. The cushion cover can be installed or removed from the backrest and headrest according to usage requirements. The air guide assembly installed on the cushion cover provides ventilation and heat dissipation for the passenger's back, avoiding the idleness of air guide assemblies fixed on the backrest and headrest. As the child grows and the headrest height is adjusted, the air guide assembly can be correspondingly adjusted to the most suitable position, improving the riding experience and adapting to different models of backrests and headrests, thus reducing the production cost of the seat.
