Description

Ventilated seating liner with improved feeling for occupants {VENTILATION SEATING LINER WITH IMPROVED COMFORT FOR SEATING}

The present invention relates to a ventilation belt module, a ventilation seating liner including the same, and a method for controlling the seating liner. In detail, the present invention provides a ventilation seating liner for infants, infants and/or children, etc., a ventilation belt module used in the ventilation seating liner, and control of the seating liner for improving the usability of occupants such as infants, infants and/or children It's about the system.

Infants, infants and/or children (hereinafter, 'infants') use mobility aids such as strollers or wagons because it is difficult for them to walk on their own. A movement assistance device such as a stroller generally includes a seat belt unit including a belt and a buckle into which the belt is inserted for safety reasons, and is configured to fix the body of the infant when the infant is seated.

In addition, according to the Road Traffic Act and its enforcement ordinances, infants under the age of 6 must be equipped with a child protective device called a car seat, and the car seat is also configured to fix the infant's body including a seat belt unit. In addition, seat belt units are included in all devices related to the seating of infants and toddlers, such as booster chairs and high chairs that assist infants in sitting, and bouncer chairs that induce sleep in infants and young children. It is generally applied to fix the body of infants and toddlers and promote safety.

However, depending on infants and toddlers, there are cases in which they avoid sitting or lying on the aforementioned stroller, wagon, car seat, booster chair, high chair, and/or bouncer chair, or dislike wearing a seat belt unit. The psychology of infants and young children not wanting to wear the seat belt unit may be due to various factors, but the main factors include crampiness as if it is tightened by a belt crossing the body or an increase in body temperature due to the tightening of the belt.

In particular, in recent years, due to the problem of fine dust, etc., there are many cases where the stroller frame is covered with a stroller cover that can block outside air and the inside, and in this case, the cramped seat belt or body temperature rise problem may be further exacerbated.

Republic of Korea Patent Publication No. 20-2020-0001227 (2020.06.12.) 'Seat for infants with ventilation cooling device' Republic of Korea Patent No. 10-2115532 (2020.05.26.) 'Ventilation seat for chair'

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

For example, Patent Document 1 discloses a seat for infants and toddlers provided with a ventilation cooling device. Patent Document 1 discloses application of a seat having a ventilation function to a seat portion supporting the hip of a seated person and a backrest supporting the back of a seated person as a ventilation seating liner used for a stroller liner or the like.

Moreover, Patent Document 2 discloses a ventilation seat for chairs used on a general chair. Patent document 2 also can provide a ventilation function to the buttocks vicinity of a seated person similarly to patent document 1.

As such, when the ventilation function is provided near the buttocks and back of the seated person's body, which has a large area in contact with the chair, etc., it is possible to greatly improve the feeling of use of the seated person and provide comfort. However, in the case of infants, infants and/or children, unlike adults, the inventor of the present invention has completed the invention by noting that it may not be sufficient to provide a ventilation function to the buttocks and back.

That is, the upper body of an adult has an inverted trapezoidal body shape, whereas the body shape of an infant has a barrel-shaped body shape, and the skeleton changes to a substantially rectangular body shape around the age of 5 years. Due to this difference in upper body shape, body temperature may not be discharged smoothly and heat may be trapped in the vicinity of the body.

In particular, in the case of a seating liner for infants, for safety reasons, or to give a feeling of enveloping infants and toddlers, it is generally concave and configured to cover the left and right sides of the seated infants. Accordingly, the thermal blockage problem in which the heat generated due to the above-described body temperature is not sufficiently dissipated and is trapped in the vicinity of the seating liner is further exacerbated.

In addition, infants and toddlers have a body temperature of 0.5°C to 1°C higher than adults, and the degree of body temperature rise is large in joint areas, such as the armpit, popliteal fossa, wrist, groin, hip joint, and popliteal region, as the skin is folded. Even the above body parts are generally soft and vulnerable to skin diseases such as sweat spots and atopic dermatitis.

Above all, adults can change their posture to lower body temperature, act to lower body temperature, or express their intention when body temperature rises. This cannot be done, and if the guardian does not recognize this, infants and toddlers have no choice but to endure the phenomenon of thermal blockage. And this experience can act as a psychological driver for infants and toddlers not to want to sit in a stroller or car seat.

That is, in the case of a seating liner for infants and toddlers, the ventilation function around 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 seating liner capable of improving the thermal closure phenomenon.

In an exemplary embodiment, at least some of the belts 210 , 220 , 230 , 240 , and 250 may be configured to be attached to and detached from the buckle 290 . For example, at one end of the first belt 210 , the second belt 220 , the fourth belt 240 , and the fifth belt 250 , the buckle 290 and the clip that can be inserted and fixed are positioned, and the third A buckle 290 may be disposed at one end of the belt 230 . The other ends of the first belt 210 , the second belt 220 , the third belt 230 , the fourth belt 240 , and the fifth belt 250 may be fixedly coupled to the seating unit 100 . .

The belt covers 215 , 225 , 235 , 245 , and 255 may have a shape that at least partially surrounds the belts 210 , 220 , 230 , 240 and 250 . The belt cover (215, 225, 235, 245, 255) is located in a portion where the belt (210, 220, 230, 240, 250) and the seated person's body abut, for example, a portion from the seater's shoulder to the clavicle, the side area, etc. to provide a cushion function can be performed. To this end, the cross-sectional thickness of the belt cover (215, 225, 235, 245, 255) may be greater than the cross-sectional thickness of the belt (210, 220, 230, 240, 250).

The belts 210 , 220 , 230 , 240 and 250 may have high tensile strength and low elasticity enough to fix the user's body from the seating unit 100 when an impact occurs. On the other hand, the belt cover (215, 225, 235, 245, 255) is different from the belt (210, 220, 230, 240, 250), not a component provided to fix the user's body, the belt (210, 220, 230, 240, 250) compared to the belt (210, 220, 230, 240, 250) because it is a component that provides a cushioning function and ventilation function to prevent discomfort that occurs when the user's body is tightened. It may have low tensile strength or high elasticity.

Specifically, the first belt cover 215 is located in a region from the seater's left shoulder to the left clavicle, the second belt cover 225 is located in the seated person's right shoulder to the right clavicle, and the third belt cover ( 235) may be located near the lower abdomen of the seated person. In addition, the fourth belt cover 245 may be located in a portion extending from the left armpit to the side of the seated person, and the fifth belt cover 255 may be located in a portion extending from the right armpit to the side of the seated person. However, the present invention is not limited thereto.

In an exemplary embodiment, the belt cover (215, 225, 235, 245, 255) according to the present invention may provide a cushion function and a ventilation function at the same time. For example, the belt covers 215 , 225 , 235 , 245 , and 255 may be physically formed integrally with each other or separated from the first part 215a , the second part 215b , and the third part 215c . may include

More specifically, the first portion 215a and the second portion 215b may form a first channel together. The first channel may be a portion through which the belts 210 , 220 , 230 , 240 and 250 are inserted. As described above, the belt covers (215, 225, 235, 245, 255) extend along the belts (210, 220, 230, 240, 250), at this time both ends of the first channel, specifically the belt cover ( 215 , 225 , 235 , 245 , and 255 may have both ends in an extended direction in an open state. Through this, the belt covers (215, 225, 235, 245, 255) are separated from the belts (210, 220, 230, 240, 250) without being fixed, and can be configured to be freely movable, depending on the body shape and needs of the occupant. Accordingly, the positions of the belt covers 215 , 225 , 235 , 245 , and 255 providing a cushion function and a ventilation function can be adjusted.

The second portion 215b and the third portion 215c may together form a second channel. The second channel may form a flow channel as will be described later. This will be described later. Unlike the first channel, both ends of the second channel may be in a closed state. The second channel may be a part through which air flows by being fluidly connected to the flow path units 310 , 320 , and 340 . Therefore, it is necessary to close both ends of the second channel, specifically, both ends in the extending direction of the belt covers 215, 225, 235, 245, 255 to prevent air from leaking or leaking through the ends. Air flowing along the second channel may be discharged through the third portion 215c as will be described later.

A belt, for example, the first belt 210 may be positioned in the space between the first part 215a and the second part 215b. A front side of the first portion 215a may be a side facing the body of the occupant in the opposite direction. That is, in a cross section perpendicular to the extending direction of the first part 215a and the second part 215b of the first belt cover 215 , the first part 215a and the second part 215b form an internal space thereof. and a first belt 210 may be disposed in the inner space. The first part 215a and the second part 215b may be configured to be opened and closed using a coupling means such as Velcro.

Also, a space between the second part 215b and the third part 215c may form a flow channel. As will be described later, air may flow through the flow path, and a ventilation function may be provided to the occupant. A back side of the third portion 215c may be a side facing the body of the occupant. That is, in a cross section perpendicular to the extending direction of the second part 215b and the third part 215c of the first belt cover 215 , the second part 215b and the third part 215c define the inner space thereof. and the inner space may form a flow path. The second part 215b and the third part 215c may be configured to be non-openable.

In particular, the second part 215b and the third part 215c may be interposed between the belts 210 , 220 , 230 , 240 , and 250 and the body of the occupant to provide a cushioning function. To this end, the thickness of the second portion 215b and/or the third portion 215c may be greater than the thickness of the first belt 210 , respectively. Also, a flow path through which air flows may be interposed between the belts 210 , 220 , 230 , 240 , and 250 and the body of the seated person. That is, the first channel may be spaced apart from the user with the second channel interposed therebetween.

In an exemplary embodiment, the first part 215a and the third part 215c may be made of different materials. For example, the first portion 215a may be made of a material having relatively low air permeability compared to the third portion 215c. On the other hand, the third part 215c may be made of a material having relatively high air permeability compared to the first part 215a or the second part 215b. Also, the thickness of the third portion 215c may be smaller than the thickness of the second portion 215b. Through this, the air flowing through the flow passage may pass through the third portion 215c and be sprayed to the seated person. In some embodiments, the third portion 215c may have an opening (not shown) through which air may be injected. When the belt covers 215 , 225 , 235 , 245 , and 255 have openings formed on the rear side, a high air blowing rate can be achieved.

The belt covers 215 , 225 , 235 , 245 , and 255 may not be directly fixed to the seating unit 100 . That is, as described above, the belt covers 215 , 225 , 235 , 245 , and 255 may be separated from the belts 210 , 220 , 230 , 240 and 250 to freely adjust their positions. Also, the belt covers 215 , 225 , 235 , 245 , and 255 and the flow path units 310 , 320 , 340 may not be directly fixed to the buckle 290 .
