Description
본 발명은 자동차의 탑승자보호용 시트구조에 관한 것으로, 특히 외부충격이 발생할 때 탑승자가 윈드실드 측으로 부딪히거나 조정핸들 하부의 페달부위로 떨어지는 것을 예방할 수 있는 자동차의 시트구조에 관한 것이다.The present invention relates to a seat structure for occupant protection of a vehicle, and more particularly to a seat structure of a vehicle that can prevent the occupant from colliding toward the windshield side or falling to the pedal portion of the lower adjustment handle when an external shock occurs.
일반적으로, 자동차의 전방시트(107)에 앉아 있는 탑승자는 교통사고 등에 의해 자동차에 외부충격이 가해졌을 때, 제4도에 도시된 바와 같이 윈드실드(105)에 부딪혀서 차실외부로 이탈되어 나가거나 조정핸들(106) 하부의 페달부위로 떨어지게 된다.In general, the occupant sitting on the front seat 107 of the vehicle, when an external shock is applied to the vehicle due to a traffic accident, etc., as shown in FIG. 4 hits the windshield 105 to leave the outside of the vehicle or The pedal falls below the adjustment handle 106.
여기서, 조정핸들(106) 하부로 탑승자가 떨어지는 것은 통상적으로 서브머린현상(sub-marine phenamenon)이라고 불리워지는 바, 이러한 서브머린현상을 방지하기 위하여 종래에는 제5도 및 제6도에 도시된 바와 같이, 전방시트(101, 111)의 쿠션을 지지하는 내부프레임(103, 113)의 앞부분을 상향으로 절곡시켜 전방시트(101)의 앞부분 또는 전방시트(111)의 중앙부분에 서브머린 방지턱(104, 114)을 형성하였다. 이에 따라, 외부충격이 발생될 때, 상기 방지턱(104, 114)에 탑승자의 엉덩이가 걸려 탑승자는 조정핸들(106) 하부의 페달부위로 떨어지지 않게 된다.Here, the falling of the occupant under the steering wheel 106 is commonly referred to as sub-marine phenamenon, which is conventionally shown in FIGS. 5 and 6 to prevent such submarine phenomenon. Likewise, the front part of the inner frame 103, 113 for supporting the cushion of the front seat 101, 111 is bent upward to the submarine prevention jaw 104 in the front part of the front seat 101 or the center of the front seat 111. , 114). Accordingly, when an external shock is generated, the butt of the occupant is caught by the bumps 104 and 114 so that the occupant does not fall to the pedal portion of the lower portion of the adjustment handle 106.
그런데, 서브머린 방지턱(104)을 전방시트(101)의 앞부분에 형성시키는 경우에는 돌출부위에 탑승자의 다리가 걸려서 탑승자가 착석하기가 불편하여 승차감이 좋지 않다는 문제점이 있고, 서브머린 방지턱(114)을 전방시트(111)의 중앙부분에 설치하는 경우에는 외부충격시 탑승자가 서브머린 방지턱(114)을 작용점으로 하는 회전모멘트를 받게 되어 윈드실드(105) 측으로 튀어나가서 윈드실드(105)에 부딪히거나 차실외부로 이탈되어 나가는 문제점이 있게 된다.However, when the submarine bumps 104 are formed at the front of the front seat 101, there is a problem in that the occupant's legs are caught on the protruding portion and the passengers are inconvenient to sit, resulting in poor riding comfort. In the case of installing in the center portion of the front seat 111, when the external impact, the passenger receives a rotation moment using the submarine preventive jaw 114 as a working point to jump to the windshield 105 side to hit the windshield 105 or There is a problem of leaving the outside of the vehicle.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 우수한 승차감을 제공하면서도 외부충격시 서브머린 현상 및 탑승자의 차실외부로 이탈됨을 방지할 수 있는 자동차의 탑승자보호용 시트구조를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to provide a seat structure for protecting the occupant of the vehicle that can prevent the departure of the submarine phenomenon and the occupant of the occupant during the external impact while providing excellent ride comfort. There is a purpose.
상기의 목적을 달성하기 위한 본 발명은, 내부프레임에 설치되어 하부시트쿠션의 하중을 지지하는 내부지지대는 전방부 양측에 걸림스프링에 의해 내부프레임에 요동가능하게 고정되고, 내부지지대의 후방부에는 걸림대가 고정설치되어, 외부충격이 발생될 때 걸림대가 내부프레임으로부터 이탈되어 내부지지대의 후방부가 아래쪽으로 기울어지도록 되어 있다.The present invention for achieving the above object, the inner support which is installed on the inner frame to support the load of the lower seat cushion is fixed to the inner frame by a locking spring on both sides of the front side so as to be swingable, The hanger is fixedly installed, and when the external shock occurs, the hanger is separated from the inner frame so that the rear portion of the inner support is inclined downward.
이와 같은 본 고안의 기술구조에 의해, 승차감을 잃지 않고도 외부충격시 서브머린 현상이 방지함과 아울러 탑승자가 윈드실드 측으로 이탈되어 외부로 나가지 않게 된다.By the technical structure of the present invention, the submarine phenomenon is prevented at the time of the external shock without losing the ride comfort, and the occupant is separated to the windshield side and does not go out.

이하, 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.
제1도는 본 발명에 따른 자동차의 탑승자보호용 시트구조를 구성하는 내부프레임(3) 부분의 평면도이고, 제2도는 제1도의 자동차의 탐승자보호용 시트구조의 사시도이다. 이들 도면에 도시된 바와 같이, 자동차에 탑승하는 탑승자가 착석하게 되는 자동차의 전방시트는 탑승자의 엉덩이가 받쳐주는 하부시트쿠션(1)과 탑승자의 등을 지지하는 측방시트쿠션(2)으로 이루어져 차실내의 저면에 고정되어 있다. 이들 시트쿠션 내부에는 골격역할을 하는 프레임이 설치되어 있는 바, 특히 하부시트쿠션(1) 내부의 가장자리에는 내부프레임(3)이 상호 조합되어 사각형상을 이루고 있다. 이 내부프레임(3)의 내부에는 내부지지대(4)가 설치되어 탑승자의 체중을 지지할 수 있도록 되어 있다.FIG. 1 is a plan view of a part of an inner frame 3 constituting a seat protection structure of a vehicle according to the present invention, and FIG. 2 is a perspective view of a rider protection seat structure of the vehicle of FIG. As shown in these figures, the front seat of the car to be occupied by the occupant of the vehicle consists of a lower seat cushion (1) supported by the passenger's hips and a side seat cushion (2) supporting the passenger's back. It is fixed to the bottom of the room. In these seat cushions, a frame serving as a skeleton is provided. In particular, the inner frame 3 is combined with each other at the edge of the lower seat cushion 1 to form a quadrangular shape. The inner support 4 is installed inside the inner frame 3 to support the weight of the occupant.
상기 내부지지대(4)는 전방부 양측을 1쌍의 걸림스프링(5)에 의해 내부프레임(3)에 요동가능하게 고정되고, 후방부에 1쌍의 걸림대(6)가 고정설치되어 내부프레임(3)에 이탈가능하게 걸려 있다. 즉 내부지지대(4)의 전방부는 걸림스프링(5)에 의해 지지되고, 후방부는 내부프레임(3) 일측에 걸림대(6)가 얹혀져 지지되도록 되어 있다. 그리고, 상기 내부지지대(4)는 중앙에 탑승자의 체중을 분산지지하도록 1쌍의 지지스프링(7)이 설치되어 있다.The inner support 4 is fixed to the inner frame 3 by a pair of engaging springs 5 on both sides of the front part so as to be swingable, and a pair of engaging bars 6 are fixedly installed on the rear part of the inner frame ( 3) is detachably hung. In other words, the front portion of the inner support 4 is supported by the locking spring 5, the rear portion is to be supported by the latch 6 is mounted on one side of the inner frame (3). And, the inner support (4) is provided with a pair of support springs (7) to distribute the weight of the occupant in the center.
여기서, 만약 차량이 충돌될 경우 내부지지대(4)는 내부프레임(3)의 전방으로 이동함으로써 걸림대(6)가 내부프레임(3)으로부터 이탈하여 내부지지대(4)의후방부가 아래쪽으로 기울어지게 된다.Here, if the vehicle collides, the inner support 4 moves forward of the inner frame 3 so that the latch 6 is separated from the inner frame 3 so that the rear portion of the inner support 4 is inclined downward. .
이와 같은 구조에 의하여 자동차가 충돌 등에 의해 외부충격을 받게 되면, 예를 들어 그 충격이 자동차의 전방으로부터 가해지게 되는 경우에는 탑승자 및 탑승자가 착석한 전방시트는 동시에 자동차 전방으로 관성력을 받게 된다. 이때, 전방시트 내부의 내부지지대(4)도 자동차의 전방으로 관성력을 함께 받으면서 이동하게 된다. 내부지지대(4)가 전방으로 이동하게 되면, 내부지지대(4) 후방부의 걸림대(6)가 내부프레임(3)으로부터 이탈되면서 내부지지대(4)의 후방부가 밑으로 기울어지게 된다. 이에 따라, 탑승자는 제3도에 도시된 바와 같이, 엉덩이 부분이 밑으로 가라앉으면서 조정핸들 하부의 페달부위로 떨어지거나 윈드실드측으로 부딪히지 않게 된다.When the vehicle is subjected to an external shock by a collision or the like by such a structure, for example, when the impact is applied from the front of the vehicle, the occupant and the front seat in which the occupant is seated receive inertial force toward the front of the vehicle at the same time. At this time, the inner support 4 inside the front seat is also moved while receiving an inertial force toward the front of the vehicle. When the inner support 4 is moved forward, the rear end of the inner support 4 is inclined downward while the catch 6 of the rear portion of the inner support 4 is separated from the inner frame 3. Accordingly, as shown in FIG. 3, the occupant does not fall to the pedal part of the lower part of the adjustment handle or hit the windshield side while the hip part sinks downward.
이상에서 설명한 바와 같이 본 발명에 따른 자동차의 탑승자보호용 시트구조에 의하면, 우수한 승차감을 제공하면서도 외부충격시 서브머린 현상을 방지함과 아울러 탑승자의 차실외부로 이탈되어 부상당하는 것을 예방할 수 있게 되는 것이다.As described above, according to the seat structure for protecting a passenger of an automobile according to the present invention, while providing an excellent ride comfort, it is possible to prevent the submarine phenomenon at the time of the external impact and to prevent being injured by leaving the outside of the passenger's cabin.
