For the design of the seat structure, because the inflatable automobile child safety seat is an inflatable automobile child safety seat, the sizes of all parts of the body of the child safety seat change along with the growth of the child, so the size of the seat which can simultaneously meet the use requirements of children of different ages is selected according to the size of the body of the child of 4-12 years old in the design on the basis of the design of the traditional child seat. Therefore, the invention searches relevant literature data and designs relevant sizes by taking a Chinese child sitting posture human body size table of 4-12 years old as a standard.
1. Seat cushion width design
The width of the seat surface is designed according to the width of the buttocks of the child, so that the child is completely supported, and meanwhile, a part of movable space is reserved in the seat for conveniently adjusting the sitting posture of the child. The seat width is greatly affected by the hip width of the child, and should be considered comprehensively. As can be seen from table 1, the hip widths of children of different age groups at 95% percentile are 242mm, 301mm, 329mm, respectively; the sizes of the parts below 5 percent are 191mm, 214mm and 244mm respectively, and if the width of the seat is too small, the space for children to move is lacked, so that the comfort is greatly reduced; if the width of the seat is too large, the seat covering feeling is not obvious, and the seating experience is influenced, so that the width of the seat is selected within the range of 244-329mm of the inner width and 340-470mm of the outer width, and the comfort requirement of children of 4-12 years old can be met. The inner and outer widths of the seat of the present invention are preferably designed to be 329mm and 469mm, respectively.
TABLE 1
| Size of human hip | 4-6 years old children | 7-10 years old children | Children 11-12 years old |
| 5％ | 191 | 214 | 244 |
| 95％ | 242 | 301 | 329 |
2. Seat height design
The height of the seat surface is known, when the seat surface is too low, thighs cannot touch the seat surface, body pressure is too concentrated on the buttocks, meanwhile, legs are in a forward bending state, muscle load is increased, the gravity center is too far behind, and the chair is difficult to rise from the seat; when the seat surface is too high, the front half of the thigh and the fossa knee are pressed, resulting in poor blood circulation. Therefore, when the height of the seat surface of the seat is designed, the situations of too high and too low seat surface are avoided, and reasonable seat height and body pressure distribution are sought. The height of the children in the growth period changes faster, so the selection of the height of the seat surface is more careful to meet the use requirements of the children with different heights. According to the principle that the front edge of the seat surface of the child seat is 3-5cm lower than the height of the knee nest of the child, the range of the installation height of the seat is designed to be 90-160mm, and the installation height of the seat is preferably designed to be 160mm in the invention.
3. Design of backrest height
When a person sits in a straight posture, the trunk cannot be supported at all, and the muscles of the back gradually fatigue, so that a backrest is needed to make up for the defect. The inner height of the backrest of the seat is not less than 600mm, the specific height can be adjusted upwards according to the growth condition of the child, the height of the backrest is 550mm for 4-6 years old children, 625mm for 7-10 years old children and 693mm for 11-12 years old children, and the height of the designed seat is preferably 700mm by considering the thickness of clothes and adding proper functional correction.
4. Backrest width design
The width of the backrest of the seat is determined by the maximum body width of the child, and the statistical data of the relative sizes of the children show that the body width of the children in 95% percentile of the children in 11-12 years old is 360mm, and in addition, a part of space is reserved for the children to adjust the posture so as to improve the riding comfort, so the width of the backrest is preferably designed to be 399mm.
5. Backrest inclination angle design
In order to maintain the normal natural shape of the spine of the child and increase the riding comfort, it is most suitable to set the inclination angle of the seat back and the seat cushion within the range of 90-115 ° because the body is slightly reclined when a person leans on the seat back with the inclination within this range, just conforming to the natural curve of our waist being slightly backwardly flexed, so the inclination angle of the seat back and the seat cushion of the present invention is preferably set to 100 °.
In order to ensure that the child seat can be fixed, the bottom of the seat 1 and the back side of the buffer support seat 4 are respectively provided with a first assembling part 7 and a second assembling part 8 which extend outwards, the first assembling part 7 and the second assembling part 8 are respectively fixedly connected with the automobile seat, and the child seat can be fixed with a child buckle on an automobile through an automobile safety belt or an additionally arranged safety bandage.
