As is well known, the safety seat for infants is an auxiliary device that is mounted and fixed to the seat of a vehicle so that infants or children who cannot wear a seat belt can be safely boarded in a vehicle. is covered with a cover having a cushioning function.

종래의 유아용 안전시트 구조체의 일 례로서, 대한민국 등록특허 제10-1854546호(2018.05.03.공고.)가 제안된 바 있는 것으로서, 그 구성은 도 6 내지 도 8에 도시된 바와 같이 차량운행시 유아의 등을 지지하며, 차량에 구비된 차량의 좌석에 어깨벨트(2) 및 허리벨트(3)로 구성되는 안전벨트에 의해 2점식 또는 3점식으로 구분되어 고정할 수 있도록 제1, 2걸림홈(11, 13)이 각각 형성되어 차량 좌석에 고정되는 등받이체(10); 상기 등받이체(10)의 하부에 설치되어 유아의 엉덩이를 지지하는 착석체(20);가 포함되며, 상기 등받이체(10)는 착석체(20)와 접하는 부위에 수용부(15)가 형성되고, 상기 착석체(20)는 수용부(15)에 수용되는 걸림돌기(21)가 형성되며, 상기 등받이체(10)의 하부 일측과 착석체(20)의 일측은 힌지구(16)에 의해 힌지체결되어 등받이체(10) 또는 착석체(20)가 힌지회동이 이루어지도록 되어 있다. As an example of a conventional child safety seat structure, Republic of Korea Patent Registration No. 10-1854546 (published on May 3, 2018) has been proposed, and the configuration thereof is as shown in FIGS. 6 to 8 when driving a vehicle. The first and second latches to support the back of the infant and to be divided into two-point or three-point type by a seat belt consisting of a shoulder belt (2) and a waist belt (3) on a vehicle seat provided in the vehicle and fixed a backrest 10 having grooves 11 and 13 formed therein to be fixed to the vehicle seat; The seat body 20 is installed at the lower portion of the backrest body 10 to support the buttocks of the infant, and the backrest body 10 has a receiving part 15 formed at a portion in contact with the seat body 20 . The seating body 20 is provided with a locking protrusion 21 that is accommodated in the receiving part 15, and the lower one side of the backrest body 10 and one side of the seating body 20 are on the hinge 16. It is hinged by the hinge so that the backrest 10 or the seat body 20 is hingedly rotated.

또한, 상기 등받이체(10)의 하부 양측으로 유아의 엉덩이의 양측의 이탈을 방지하도록 지지부(19)가 형성되고, 상기 등받이체(10)의 상측으로 유아의 머리를 지지할 수 있도록 원호형의 판으로 이루어지는 머리지지판(40)이 구비된다. 그리고 등받이체(10)와 착석체(20)에 각각 형성된 수용부(15)와 걸림돌기(21)의 걸림구조로 하여금 등받이체(10)와 착석체(20)가 견고하게 고정되어 유아의 안전성을 확보할 수 있도록 하고 있다.In addition, support portions 19 are formed on both lower sides of the backrest body 10 to prevent separation of both sides of the infant's buttocks, and arc-shaped to support the infant's head toward the upper side of the backrest body 10 . A head support plate 40 made of a plate is provided. And the locking structure of the receiving part 15 and the locking protrusion 21 respectively formed on the backrest 10 and the seating body 20 ensures that the backrest 10 and the seating body 20 are firmly fixed to ensure the safety of infants. to be able to obtain

한편, 고속으로 주행하는 자동차가 다른 사물과 충돌했을 때는 관성의 법칙과 운동에너지로 인해 상상할 수 없는 큰 에너지가 발생한다. 예컨대 차가 정지상태에서 급출발할 때 차내승차자의 신체가 순간적으로 뒤로 제쳐지는 경우나 주행중 급제동할 때 차내승차자의 신체가 전방으로 쏠리는 현상은 모두 관성(inertia)의 영향을 받기 때문이다. 따라서 유아용 안전시트에서 가장 관건이 되는 것은 유아나 어린이를 차량의 충돌 및 급제동시 발생하는 전방 쏠림현상으로부터 얼마나 안전하게 보호할 수 있는가에 달려 있다.On the other hand, when a high-speed vehicle collides with another object, unimaginably large energy is generated due to the law of inertia and kinetic energy. For example, when the vehicle starts abruptly from a standstill, the body of the occupant is momentarily pushed back, or when the occupant's body is pulled forward during sudden braking while driving, all are affected by inertia. Therefore, the most important thing in a child safety seat depends on how safely it can protect an infant or child from a forward leaning phenomenon that occurs during a vehicle collision or sudden braking.

이를 위해 종래에는 등받이체(10)의 하부 양측에, 착석체(20)의 상면에 지지되는 지지부(19)를 일체로 형성하고, 등받이체(10)의 하단면에 전방 개구형의 수용부(15)를 형성하여 등받이체(10)를 전방측으로 회동시킬 때 수용부(15)가 착석체(20)의 후방측에 형성된 걸림돌기(21)에 걸려 고정되게 함으로써 안전벨트에 의해 유아가 묶여 있는 등받이체가 차량 충돌 및 급제동에 의해 순간적으로 전방측으로 쏠리는 현상을 예방하고자 하였으나, 지지부가 등받이체의 전체 길이 및 면적에 비해 등받이체의 하부 양측에만 국부적으로 집중되어 있고 수용부 및 걸림돌기에 의한 고정력은 극히 미미해 차량 충돌 및 급제동시 상상할 수 없는 큰 에너지로 작용하는 등받이체의 순간 전방 쏠림현상을 실질적으로 방어 및 예방하는데 충분한 지지력을 갖지 못했다.To this end, in the prior art, on both sides of the lower part of the backrest body 10, the support parts 19 supported on the upper surface of the seat body 20 are integrally formed, and a front opening type receiving part ( 15) is formed so that when the backrest 10 is rotated to the front side, the receiving part 15 is caught by the locking protrusion 21 formed on the rear side of the seat 20, so that the infant is tied by the seat belt. Although it was attempted to prevent the phenomenon that the backrest is momentarily tilted forward due to a vehicle collision and sudden braking, the support is locally concentrated only on both lower sides of the backrest compared to the overall length and area of the backrest, and the fixing force by the receiving part and the locking protrusion is extremely It did not have sufficient support to effectively defend and prevent the instantaneous forward leaning of the backrest, which acts as an unimaginable large energy during a vehicle collision and sudden braking, which is insignificant.
