Description

Ventilation belt module, ventilation seating liner including the same, and control method of seating liner {VENTILATION BELT MODULE, VENTILATION SEATING LINER INCLUDING THE SAME, AND METHOD OF CONTROL SEATING LINER}

The present invention relates to a ventilation belt module, a ventilation seating liner including the same, and a control method of the seating liner. Specifically, the present invention is a ventilation seating liner for infants, infants and/or children, a ventilation belt module used in the ventilation seating liner, and control of a seating liner to improve the feeling of use of a seated person such as infants, infants and/or children It's about the system.

Infants, infants, and/or children (hereinafter referred to as'infants') use mobility aids such as strollers or wagons because they have difficulty walking on their own. Movement aids such as a stroller generally include a seat belt unit composed of a belt and a buckle into which the belt is inserted for safety reasons, and are generally configured to fix the body of the infant when the infant is seated.

In addition, according to the Road Traffic Act and its enforcement decree, infants under the age of 6 must be equipped with protective equipment for infants, commonly referred to as a casi, and the car seat is also configured to fix the infant's body including a seat belt unit. In addition, a seat belt unit is provided for all devices related to the seating of infants and toddlers, such as a booster chair and a high chair to assist infants and toddlers to sit, and a bouncer chair to induce sleep for infants and toddlers. It is generally applied to secure the body of infants and toddlers and to ensure safety.

However, depending on infants and toddlers, there are cases in which they avoid sitting or lying on the above-described stroller, wagon, car seat, booster chair, high chair, and/or bouncer chair, or hate wearing a seat belt unit. The psychology that infants and toddlers do not want to wear the seat belt unit may be due to various factors, but the main factors may be the cramping that seems to be tightened by a belt crossing the body or an increase in body temperature due to the tightening of the belt.

In particular, due to a recent problem of fine dust, there are many cases where a stroller cover that can block the outside air and the inside is covered on the stroller frame, and in this case, the problem of cramping the seat belt or an increase in body temperature may be further aggravated.

Republic of Korea Patent Publication No. 20-2020-0001227 (2020.06.12.)'Infant and toddler seat with ventilation cooling device' Republic of Korea Patent Registration No. 10-2115532 (2020.05.26.)'Chair ventilation seat'

For this reason, a variety of seating liner products having a ventilation function are being developed. Ventilated seating liners not only products for infants and toddlers, but also seating liners for adults are being applied to vehicles.

For example, Patent Document 1 discloses a sheet for infants and toddlers equipped with a ventilation cooling device. Patent Document 1 discloses that a sheet having a ventilation function is applied to a seating portion for supporting a seated person's buttocks and a backrest portion for supporting a seated person's back as a ventilation seating liner used for a stroller liner or the like.

In addition, Patent Document 2 discloses a ventilation seat for a chair used by placing it on a general chair. Patent Document 2 Also, similarly to Patent Document 1, a ventilation function can be provided in the vicinity of the seated person's buttocks.

In this way, when the ventilation function is provided in the vicinity of the hips and back having a large area in contact with the chair, among the body of the occupant, comfort can be provided by greatly improving the feeling of use of the occupant. However, in the case of infants, infants, and/or children, unlike adults, the inventors of the present invention have come to complete the invention, conceiving that it may not be sufficient to provide a ventilation function on the buttocks and back.

In other words, the upper body of an adult has a historical trapezoidal body, while the infant's body has a barrel-shaped body, and the skeleton changes to a substantially rectangular body around the age of 5 years. Due to the difference in upper body shape, body temperature may not be discharged smoothly and heat may be trapped near the body.

In particular, in the case of an infant seating liner, it is generally concave for safety reasons or to give a feeling of warmly wrapping the infant and to a shape that covers the left and right sides of a seated infant. Therefore, the heat caused by the above-described body temperature does not sufficiently dissipate, and the heat closure problem that is trapped near the seating liner is further aggravated.

Moreover, infants and toddlers have a body temperature of 0.5°C to 1°C higher than that of adults, and joints, such as armpits, armpits, wrists, groin, hip joints, and knees, have a high degree of body temperature rise due to the folds of the skin. Even the above body parts generally have soft skin and are susceptible to skin diseases such as heat rash and atopy.

Above all, if the body temperature rises, adults can change their postures to lower body temperature, act to lower body temperature, or express their intentions, but children, especially infants, take active measures to lower body temperature due to physical/mental immaturity. It cannot be done, and if the guardian does not recognize it, infants and toddlers have no choice but to withstand the phenomenon of heat closure. And this experience can act as a psychological driver for infants and young children to not want to sit in a stroller or car seat.

That is, in the case of a seating liner for infants and young children, the ventilation function in the vicinity of the buttocks and back is not sufficient, and it is necessary to more actively solve the thermal closure phenomenon.

Accordingly, the problem to be solved by the present invention is to provide a sheeting liner capable of improving the heat closing phenomenon.
