Description
Technical Field
The invention relates to the technical field of furniture, in particular to an extension type baby family chair capable of being adjusted according to the growth of a baby body.
Background
The infant period is at home most of the time except for the guardian carrying his outdoor activities, but the time at home is longer when the guardian encounters rain, snow and strong wind, and the waking time of the infant is more and more increased with the increase of the month-old. Infants from 0 months to 7 months of age increase in waking time from about 3 hours to 8 hours a day and are more lying in bed or on a sofa after waking, but as the months of age of the infants increase they are not satisfactory for lying on the ceiling, nor are guardians likely to lean around them to make them look around slightly while they are awake all the time, but they want to know everything around, but they have no ability to sit alone or walk alone.
The seats that have been available for a long time now around us are generally intended for infants and adults who can sit stably independently, or a floor-type baby reclining chair, the age of the baby is 6 months later, which is recognized by general medicine according to the development of baby spine, the real sitting stability is about 8 months, and the infant with the age of 0-7 months can sit on the chair with the spinal column slowly approaching 90 degrees along with the increase of the age of the month, the fact proves that the infant with the age of 7 months is less and less sits on the chair with the backrest with the inclination angle, the inclination angle of the chair needs to approach 180 degrees, if the inclination angle approaches 90 degrees, the infant can not sit, and the closer the inclined angle of the backrest of the chair is to 90 degrees, the more visible the degree of paralysis and distortion of the back of the infant is, it follows that a seat suitable for an infant seat and an adult seat that can be stably seated independently is completely unsuitable. If parents sometimes want to let a baby who cannot sit upright and stably sit on a sofa to watch television, the back of the baby is padded with a thick bedding pillow and the like, the baby starts to twist and incline from the shoulder to the hip due to the fact that the spine is soft and muscle is weak, and finally falls to one side, and the baby does not know to support the baby to sit upright again in the falling process.
According to the book of the complete set of the three-dimensional infant care illustrated by the three-dimensional jade billows of the pediatrician, the growth and development book indicates that the first year of the newborn needs to be 25 cm, namely the first half year of the birth is 12.5 cm per month, the first year of the birth is 1-3 years old, the average year of the newborn is 12 cm per year, and then a proper infant seat needs to be formulated according to the requirements of the growth and development of the infant.
The existing electric deck chair swing for the baby occupies a large area, is inconvenient to move, is expensive, generally ranges from 300 to 3000, generally needs to be powered on for use, and is only suitable for being placed on the ground for use.
The application numbers are: 200910108982.5 discloses a multifunctional baby chair, which is not suitable for being placed on a bed where a baby usually sits, and is not designed for the characteristics of spine development of a baby of 0-7 months old, but it is only changed from a reclining chair to a chair, but the process of lying down to sitting down does not exist, and it is not designed according to the height development of the baby, and it is not suitable for a small baby.
At present, a chair suitable for being used on a bed, a sofa or the ground for 0-7 month-old infants is needed, and the stretching degree of the chair can be adjusted according to the difference of the spine development of the 0-7 month-old infants.
