Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in fig. 1 and 2, the present invention includes a supporting backup plate 200, the supporting backup plate 200 is fixed on the inner side of the chair back 300, i.e. the supporting backup plate 200 faces the side of the infant sitting on the safety chair, and a ventilation cavity 400 is left between the supporting backup plate 200 and the chair back 300; the outer side surface of the chair back 300 is provided with a first vent hole 3001, the first vent hole 3001 is a strip-shaped vent hole, so that the ventilation area can be enlarged, the support backup plate 200 is provided with a plurality of second vent holes 2001 which are uniformly distributed, so that the ventilation area is enlarged, the processing and forming of the support backup plate 200 are facilitated, and the first vent hole 3001 is communicated with the second vent holes 2001 through a ventilation cavity 400, so that the air circulation is facilitated; the ventilation mechanism is arranged on the chair back, so that the back ventilation of the safety chair can be realized, or the ventilation mechanism can be arranged on the supporting plate on the cushion, so that the base ventilation of the safety chair can be realized.

In order to make the air flow uniform, as shown in fig. 4, two first ventilation holes 3001 are provided on the seat back 300 and are symmetrically disposed on the left and right sides or the upper and lower sides of the outer side surface of the seat back 300, respectively, in general, the first ventilation holes 3001 are symmetrically disposed on the left and right sides of the outer side surface of the seat back 300, and the seat back 300 of the safety seat has a long bar-shaped structure, so that the ventilation area can be increased and the ventilation effect can be improved.

As shown in fig. 3, a plurality of air ducts 3002 are arranged at the corners of the chair back 300, and the air ducts 3002 are arranged in sequence, and ribs 3003 are arranged among the air ducts 3002, so that the strength of the corners of the chair back 300 can be enhanced by arranging the ribs 3003, and the overall safety performance of the safety chair can be improved.

Air duct 3002 is the circulation of air that the corresponding arrangement realized with first ventilation hole 3001, and air duct 3002 link up with ventilation cavity 400 to make whole ventilation mechanism be the connected state, realize safety seat's ventilation.
