본 고안은 차량전방충돌시 자동차의 시트를 뒷쪽으로 젖혀지게 하여 탑승자의 안전을 최대한 보장받을 수 있게 한 자동차용 시트젖힘 장치에 관한 것이다.The present invention relates to a seat retracting device for a vehicle that can be ensured to ensure the maximum safety of the occupant by flipping the seat of the car back in front of the vehicle collision.
일반적으로 차량전방충돌시의 안전장치로서는 에어백, 충돌감지장치, 가스발생장치 등이 있는 바, 이러한 장치들은 복잡한 구조와 상당한 구성부품들로 이루어져 있어서 소형차량의 경우에는 설치공간 협소등의 이유로 그 적용범위에 한계를 갖고 있었으며 특히, 에어백을 설치하는 경우 이로 인한 글로브박스의 활용공간이 그만큼 줄어들게 되는 단점과 함께 이와같은 이유등으로 소형차량에 적합한 안전장치의 개발에 대한 필요성을 절실히 느껴왔던 것이다.In general, safety devices in front of a vehicle include airbags, collision detection devices, and gas generators. These devices are composed of a complicated structure and considerable components. In particular, there has been a limit to the range, and in particular, when the airbag is installed, the use space of the glove box is reduced by that amount, and for this reason, the need for the development of a safety device suitable for a small vehicle is urgently felt.
본 고안은 이와같은 점을 감안하여 안출한 것으로서, 간단한 구조와 최소한의 구성부품으로 이루어진 안전장치 즉, 시트젖힘장치를 시트쿠션의 저부에 설치하여, 전방충돌감지에 따라 시트가 뒷쪽으로 일정각도 젖혀지게 함으로써, 탑승자의 피해를 최소화 할 수 있는 자동차용 시트젖힘장치를 제공하는데 그 목적이 있는 것이다.The present invention has been devised in view of such a point, and a safety device composed of a simple structure and a minimum of components, that is, a seat restraint is installed at the bottom of the seat cushion, and the seat is flipped to a rearward angle according to the front collision detection. It is an object of the present invention to provide a seat folding apparatus for automobiles that can minimize the damage of the occupants.
이하, 첨부도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안 자동차용 시트(10)의 시트쿠션(11) 저부에 뒷쪽에서 부터 순차적으로 설치되는 유압발생부인 오일저장탱크(12) 및 오일펌프(13)와, 유압제어부인 밸브(14) 및 배관(15)과, 작동부인 액추에이터(16)로 이루어지되, 상기 오일펌프(13)는 차속센서(17) 및 시동키(18)와 연계접속되어 작동되고 상기 액추에이터(16)의 로드(16-1)는 시트쿠션(11)의 바닥면에 클레비스 결합되는 동시에 시트쿠션(11)의 바닥 후면부는 사물보관함(19)의 윗면에 힌지결합되도록 이루어진 것이다.The oil storage tank 12 and the oil pump 13, which are the hydraulic generators, which are sequentially installed from the rear of the seat cushion 11 of the seat 10 for a vehicle according to the present invention, the valve 14 and the piping, which are the hydraulic controls, 15) and the actuator 16, which is an operating part, the oil pump 13 is operated in connection with the vehicle speed sensor 17 and the starter key 18, and the rod 16-1 of the actuator 16 is operated. The clevis is coupled to the bottom surface of the seat cushion 11 at the same time the bottom rear portion of the seat cushion 11 is to be hinged to the upper surface of the object storage box (19).
특히, 상기 오일저장탱크(12) 및 오일펌프(13)와, 밸브(14) 및 배관(15)과, 액추에이터(16)로 이루어진 시트젖힘장치는 시트쿠션(11)의 저면부와 일체로 구성되어 있는 사물보관함(19) 내부에 설치되어서, 그 주변 부품과의 작동 및 설치 간섭을 방지하는 동시에 외관성을 살릴수 있도록 되어 있다. 즉, 시트(10)의 전후이동을 조절해주는 시트트랙(20)은 상기 사물보관함(19)의 저면양측에 설치되므로 이 시트트랙(20)의 조작과 사물보관함(19)의 내부에 설치되는 시트젖힘장치의 작동과는 아무런 간섭을 받지 않고 그 작동 및 조작이 이루어 질 수 있도록 되어있다.In particular, the seat retractor consisting of the oil storage tank 12 and the oil pump 13, the valve 14 and the pipe 15, and the actuator 16 is integrally formed with the bottom portion of the seat cushion 11 It is installed inside the locker 19, which can prevent the operation and installation interference with the surrounding components, and at the same time can improve the appearance. That is, the seat track 20 for controlling the front and rear movement of the seat 10 is installed on both sides of the bottom surface of the locker 19, the seat is installed in the operation of the seat track 20 and the locker 19 It is designed to be operated and operated without any interference with the operation of the lifting device.
여기서, 상기 액추에이터(16)는 작업유체 즉, 오일이 항상 피스톤(16-2)의 한쪽으로만 작용하여 피스톤(16-2)을 움직이게 하는 단동식으로 이루어져 있으며, 이때의 액추에이터(16)내에는 항상 일정한 유압이 형성되게 한다. 예를 들면, 착석자의 체중에 비례한 시트쿠션(11)의 작동력 즉, 체중 120㎏이상의 사람이 착석했을 경우 시트쿠션(11)을 일정각도 이상 원호운동시키는데 필요한 작동력에 상응하는 유압이 형성되게 한다.Here, the actuator 16 is made of a single-acting type, in which the working fluid, that is, the oil, always acts on only one side of the piston 16-2 to move the piston 16-2. In this case, the actuator 16 Ensure constant hydraulic pressure is always established. For example, the operating force of the seat cushion 11 in proportion to the weight of the seated person, that is, when a person weighing 120 kg or more is seated, a hydraulic pressure corresponding to the operating force required to arc the seat cushion 11 over a certain angle is formed. .
또한, 상기 액추에이터(16)의 로드(16-1)는 시트쿠션(11)의 바닥면에 형성된 U자형 브라켓(21)과 클레비스 결합되는데 즉, 브라켓(21)의 양단에 핀 관통공이 뚫려있고 그 사이에 상기 로드(16-1)가 끼워져 있는 상태로 핀(22)을 관통시킴으로써 결합이 이루어지게 되어서, 시트쿠션(11)의 앞부분이 들려지게 될 때 로드(16-1)의 선단결합부에 무리한 하중이 걸려지지 않도록 되어있다.In addition, the rod 16-1 of the actuator 16 is coupled to the clevis with the U-shaped bracket 21 formed on the bottom surface of the seat cushion 11, that is, the pin through holes are drilled at both ends of the bracket 21, The coupling is made by penetrating the pin 22 with the rod 16-1 inserted therebetween, so that the front coupling portion of the rod 16-1 is lifted when the front portion of the seat cushion 11 is lifted. Do not apply excessive load on it.
이와같은 결합은 시트쿠션(11)의 저면 앞쪽부위에서 양측으로 각각 이루어지게 되므로서 시트쿠션(11)의 양측이 균등하게 들려질 수 있도록 되어 있다.This coupling is made so that both sides of the seat cushion 11 can be heard evenly because each side is made from both sides in front of the bottom of the seat cushion (11).
이와같이 구성된 본 고안의 작용효과를 첨부도면 제2도의 순서도를 참고하여 설명하면 다음과 같다.Referring to the flow chart of Figure 2 attached to the effect of the present invention configured as described above is as follows.
우선, 초기화 과정에서 시동키(18)를 ON시킨 상태에서 본 고안의 시트젖힘 장치의 정상작동여부를 점검하게 된다.First, it is checked whether or not the normal operation of the seat folding apparatus of the present invention in the state of turning on the ignition key 18 in the initialization process.
이때 시트젖힘장치가 정상적으로 작동되고 있으면 녹색램프가 약 3초간 점멸작동되고 장치에 이상이 있을 경우에는 붉은색 램프의 점등과 함께 경보음이 울리도록 되어 있다.At this time, if the seat retractor is operating normally, the green lamp blinks for about 3 seconds. If there is a problem with the device, the red lamp turns on and an alarm sounds.
여기서, 시트젖힘장치의 비작동여부는 오일펌프(13)를 구동시키는 모터(도시되지 않음)의 단선여부와 배관(15)의 누유여부를 점검하게 되며 각각 전류계 및 압력계등을 부수적으로 장착하여 점검하게 된다.Here, the non-operation of the seat retractor checks the disconnection of the motor (not shown) for driving the oil pump 13 and the leakage of the pipe 15, and additionally checks by installing an ammeter and a pressure gauge, respectively. Done.
한편, 시트젖힘장치가 정상적으로 작동되고 있을 경우 스탭(30)에 있어서 차속센서(17)로 부터의 속도값을 입력하고 다음 스탭(31)에서 │α│＞X 를 판정한다. 즉, 이미 설정되어 있는 1차 속도값 X 와 입력된 속도값 │α│ 와의 차이 여부를 판정한다. 입력된 속도값이 1차 속도값보다 크면 스텝(32)에서는 오일펌프(13)의 작동을 설정하여 오일저장탱크(12)로 부터의 오일을 이용한 1차 유압을 형성시키고 계속해서 스텝(33)에서는 감속된 속도값과 2차 속도값과 차이 여부를 판정한다.On the other hand, when the seat folding apparatus is normally operated, the speed value from the vehicle speed sensor 17 is input in the step 30, and the next step 31 determines | α |> X. That is, it is determined whether or not the difference between the primary speed value X already set and the input speed value | α | is changed. If the input speed value is greater than the primary speed value, in step 32, the operation of the oil pump 13 is set to form primary hydraulic pressure using oil from the oil storage tank 12, and then step 33 is continued. Determines whether there is a difference between the decelerated speed value and the secondary speed value.
상기 스텝(33)에서 2차 속도값보다 감속된 속도값을 작게 판정하면 오일펌프(13)의 재작동을 판정처리하고(스텝34) 또한, 스텝(35)에서는 액추에이터(16)의 작동을 판정 처리하며 스텝(36)에서는 시트쿠션(11)의 작동을 판정처리하여 시트쿠션(11)의 앞쪽이 들려지게 한다. 즉, 시트(10) 전체가 시트쿠션(11)의 저면부 뒷쪽에서 형성된 힌지결합부위를 중심으로 하여 뒷쪽으로 젖혀지게 한다.If it is determined in step 33 that the speed value decelerated is lower than the secondary speed value, the operation of the oil pump 13 is judged to be restarted (step 34), and in step 35, the operation of the actuator 16 is determined. In step 36, the operation of the seat cushion 11 is judged so that the front of the seat cushion 11 is lifted. That is, the entire sheet 10 is turned back toward the center of the hinge coupling portion formed in the rear of the bottom portion of the seat cushion (11).
한편, 상기 스텝(31)에서 기 설정값인 1차 속도값이 입력된 속도값보다 크게 판정되면 차속센서(17)에 의한 차량속도값의 재입력을 위하여 스텝(30)으로 복귀가 이루어지고, 상기 스텝(33)에서 2차 속도값이 감속된 속도값보다 크게 판정되면 스텝(37)에서는 유압펌프(13)의 작동장치를 판정처리하여 유압을 감소시키게 되며 스텝(31)으로 복귀가 이루어져 1차 속도값과의 재판정이 이루어진다.On the other hand, if it is determined in step 31 that the primary speed value, which is a preset value, is larger than the input speed value, the vehicle returns to step 30 to re-enter the vehicle speed value by the vehicle speed sensor 17, If the secondary speed value is determined to be greater than the decelerated speed value in the step 33, the step 37 determines the operating device of the hydraulic pump 13 to reduce the oil pressure and returns to step 31. A trial is made with the vehicle speed value.
여기서, 상기 스텝(32)에서 스텝(34)까지 진행이 이루어지는 동안에는 상기 오일펌프(13)는 계속 작동되어 점차적으로 상승된 유압을 형성시키게 되고, 이렇게 상승된 유압을 스텝(34)에서의 판정처리에 의해 출력제어되는 상기 밸브(14)의 열림 작동과 동시에 액추에이터(16)로의 공급이 이루어지게 되는 것이다.Here, while progressing from the step 32 to the step 34, the oil pump 13 continues to operate to form a gradually raised hydraulic pressure, and the process of determining the raised hydraulic pressure at the step 34 is performed. Simultaneously with the opening operation of the valve 14 controlled by the output, the supply to the actuator 16 is made.
이상에서와 같이 본 고안의 시트젖힘장치는 고도의 기술적 구성을 요하지 않는 간단한 구조로 이루어져 있으며 설치공간 점유율 또한 낮기 때문에 소형차량의 설치용으로 매우 유용한 장점이 있으며, 운전석이나 조수석 밑의 빈공간 활용측면에서도 매우 효율적인 면을 갖고 있는 특장점이 있는 것이다.As described above, the seat folding device of the present invention has a simple structure that does not require a high technical configuration and has a low installation space share, which is very useful for the installation of small vehicles, and also in terms of utilization of empty space under the driver's seat or the passenger seat. There is a feature that is very efficient.
