Description
본 발명은 자동차용 시트의 목부상 방지장치에 관한 것으로서, 더욱 상세하게는 시트백 내부의 양 프레임을 사이에 두고 지지부재와 가이드부재가 일체로 형성되는 동시에 상기 지지부재의 상·하면에 고정되고 전방으로 돌출되도록 패널이 형성되며 상기 가이드부재가 가이드레일에 걸려 이동이 가능하게 설치되는 한편, 상기 가이드부재의 걸림턱에 로드가 고정되고 상기 로드가 양 프레임의 가이드구멍의 하단에 설치된 스프링에 의해 지지되도록 이루어짐으로써, 충돌시 운전자의 머리가 뒤로 젖혀지는 것을 방지하기 위한 자동차용 시트의 목부상 방지장치에 관한 것이다.The present invention relates to an apparatus for preventing neck injury of an automobile seat, and more particularly, a support member and a guide member are integrally formed with both frames inside the seatback, and are fixed to the upper and lower surfaces of the support member and to the front. The panel is formed so as to protrude into the guide member is installed to be movable by the guide rail, while the rod is fixed to the locking jaw of the guide member and the rod is supported by a spring installed at the lower end of the guide hole of both frames By so doing, the present invention relates to an apparatus for preventing neck injuries of a seat for a vehicle to prevent the driver's head from falling back.
일반적으로 자동차 시트백 상단에는 운전자나 탑승자의 머리를 받쳐줄 수 있는 헤드레스트가 장착되어, 주행중 운전자나 탑승자의 머리를 편하게 받혀주는 기능을 하고 또한 충돌시에는 탐승자의 머리를 보호해주는 역활을 한다.In general, a headrest that is capable of supporting a head of a driver or a passenger is mounted at the top of a car seatback, and serves to comfortably support the head of a driver or a passenger while driving and also protects the head of an occupant in a crash.
첨부한 도 2는 종래의 후방 충돌시 탑승자의 상태를 나타내는 측면도로써, 헤드레스트(200)는 시트백(300)의 상단에 설치되어 탑승자의 머리를 받혀주고 보호해주게 된다.2 is a side view showing a state of a passenger during a conventional rear collision, the headrest 200 is installed on the top of the seat back 300 to support and protect the head of the occupant.
여기서, 100은 시트이고 400은 시트 쿠션을 나타낸다.Where 100 represents a seat and 400 represents a seat cushion.
그러나, 이와 같은 구조에서는 평상시 운전자나 탑승자가 헤드레스트와 거리를 두고 있기 때문에 갑작스런 후방 충돌시 운전자의 머리가 순간적으로 뒤로 젖혀지면서 목을 삐든지 또는 두통, 척추부 고통을 겪는 것이 흔하게 발생하게 된다.However, in such a structure, since the driver or the passenger is normally separated from the headrest, the driver's head is suddenly flipped backwards in a sudden rear collision, and it is common to suffer from a neck sprain, headache, or spinal pain.
일 예로 미국의 조사에 의하면, 주행중 충돌에 의한 상해의 연간 예상비용을 살펴보면 어느정도 경제적 손실이 발생하는지 짐작할 수 있다.For example, according to the US survey, looking at the estimated annual cost of injury from driving collisions, one can guess how much economic losses are incurred.
즉, 상해정도가 낮을 경우에 한해서는 연간 39억$가 소요되고, 또한 보험료로 지불되는 비용이 102억$를 상회한다고 보고되고 있다.In other words, if the degree of injury is low, it is reported that it costs $ 3.9 billion a year, and that the premium paid is over $ 10.2 billion.
그러므로, 이와 같이 후방 충돌에 의한 목부상을 방지할 수 있는 장치의 개발이 절실이 요구되고 있다.Therefore, there is an urgent need for the development of a device capable of preventing a neck injury due to a rearward collision.
따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 시트백 내부의 양 프레임을 사이에 두고 지지부재와 가이드부재가 일체로 형성되는 동시에 상기 지지부재의 상·하면에 고정되고 전방으로 돌출되도록 패널이 형성되며 상기 가이드부재가 가이드레일에 걸려 이동이 가능하게 설치되는 한편, 상기 가이드부재의 걸림턱에 로드가 고정되고 상기 로드가 양 프레임의 가이드구멍의 하단에 설치된 스프링에 의해 지지되도록 이루어지어 후방충돌시 운전자의 상체가 뒤로 밀림과 동시에 로드가 해제되어 지지판을 밀쳐주고 헤드레스트를 상방으로 이동시켜 줌으로써, 충돌시 운전자의 머리가 뒤로 젖혀지는 것을 방지하는데 그 목적이 있는 것이다.Accordingly, the present invention has been made in view of the above problems, so that the support member and the guide member are integrally formed with both frames inside the seatback, and are fixed to the upper and lower surfaces of the support member and protrude forward. The panel is formed and the guide member is mounted on the guide rail so as to be movable, while the rod is fixed to the locking jaw of the guide member and the rod is supported by a spring installed at the lower end of the guide hole of both frames. The driver's upper body is pushed back during the rear collision and the rod is released to push the support plate and move the headrest upward, thereby preventing the driver's head from falling back in the event of a collision.
