본 고안은 불시에 교통사고를 당함에 있어, 탑승자의 안정을 돕기위해 고안된 차량시트의 충격완충장치에 관한 것이다.The present invention relates to a shock absorber of a vehicle seat designed to help the occupant's stability in case of accidental traffic accident.
종래에는 승객을 보호하는 장치로서 주로 이용되는 안전벨트가 있었으나. 운전자를 비롯하여 탑승객 대부분이 착용치 않는 문제가 있어, 그 실효를 거두지 못하고 있으며, 또다른 안전장치로서는 범퍼의 고강성 제작으로 대비하고 있다.In the past, there was a seat belt mainly used as a device for protecting passengers. There is a problem that most of the passengers, including the driver is not worn, and the effectiveness is not achieved, and another safety device is prepared by the high rigidity of the bumper.
그러나, 전자와 후자는 추돌충격으로 차실 내부의 탑승객이 시트에서 유동이 있을 때 그 충격을 감소시켜 주지는 못하였다.However, the former and the latter did not reduce the impact of the passengers inside the cabin when there was flow in the seat due to the collision shock.
따라서, 상기 문제를 해결하기 위해 국내 실용신안(출원번호 제86-15784호)에 의해 알려진 바와같이, 차량이 불의에 추돌사고를 당했을 때, 범퍼에 내장된 박만스위치 접점으로 유압실린더가 장치된 절면시트가 뒷자석 방향으로 이동되도록 한 것이다.Therefore, in order to solve the problem, as known by the domestic utility model (Application No. 86-15784), when the vehicle is inadvertently crashed, the section of the hydraulic cylinder is equipped with a bakman switch contact built into the bumper The seat is moved in the rear magnet direction.
그렇지만, 상기와 같은 장치는 뒷좌석에 탑승자가 없을 때에는 효과를 얻을 수 있겠으나. 탑승자가 앞, 뒤좌석에 모두 있을 때는 앞뒤 승객이 더욱 큰충격을 받게 된다. 그 이유는 추돌사태시 상기 장치작동으로 앞좌석은 뒷좌석 방향으로 물러나게 되고, 동시에 뒷좌석 승객은 부딪히는 충격에 의해 앞좌석 방향으로 몸이 쏠리게 된다. 그러므로, 앞뒤 승객은 서로의 부딪히는 가속력에 의해 더욱 큰 부상을 입게되는 것이다.However, such a device may be effective when there is no occupant in the rear seat. When the occupants are in both the front and back seats, the front and rear passengers are more shocked. The reason is that in the event of a collision, the front seat retreats in the rear seat direction, and at the same time, the rear seat passenger is leaned toward the front seat by the impact that is hit. Therefore, the front and rear passengers are further injured by the collision force of each other.
따라서, 본 고안은 상기 문제점을 감안하여, 앞,뒤 승객 모두가 사고에서 오는 충격으로 부터 회대한 보호를 받을 수 있도록 안출한 것으로서, 이를 첨부된 도면에 따라 설명하면 다음과 같다.Therefore, in view of the above problems, the present invention was conceived so that both front and rear passengers can receive protection from an impact from an accident, which will be described according to the accompanying drawings.

미설명부호 50은 덕트보조 덮판, 51은 차량의 우측 앞문짝을 나타낸다.Reference numeral 50 denotes a duct assist cover plate, and 51 denotes a right front door of the vehicle.
이와같이 구성된 본 고안의 작용 및 효과를 좀더 상세하게 설명하면 다음과 같다.When described in more detail the operation and effect of the present invention configured as described above.
최초에는 먼저 자동차의 시동을 건 다음, 에어공급스위치(205)를 온(ON)한다.Initially, the vehicle is first started, and then the air supply switch 205 is turned on.
이와같은 에어공급스위치(205)를 넣게되면, 그 전원이 중앙신호 처리장치(201)에 전달되어, 이미 입력한 회로를 따라 그 전원은 에어콤프레셔(206)를 작동시켜주게 된다.When the air supply switch 205 is inserted, the power is transmitted to the central signal processing device 201, and the power supplies the air compressor 206 along the circuit that has already been input.
이에 따라 생성된 에어는 일방통행밸브(207)를 통해서 뒷좌석 공기주머니(19)에 주입되고, 일정한 압력이 팽창되면 압력계기(208)에 팽창력을 감지하여 그 신호를 중앙처리신호 처리장치(201)로 다시 보낸다.The generated air is injected into the rear seat air pocket 19 through the one-way valve 207, and when a predetermined pressure is expanded, the pressure gauge 208 detects the expansion force and transmits the signal to the central processing signal processing apparatus 201. Send back to.
이에따라 신호를 감지한 중앙신호 처리장치(201)에서는 그 신호를 받아 에어공급스위치(205)를 차단시켜 주게되어 에어콤프레셔(206)의 작동을 중단시키게 된다.Accordingly, the central signal processing device 201 that senses the signal interrupts the air supply switch 205 by receiving the signal to stop the operation of the air compressor 206.
따라서, 뒷좌석 공기주머니(19)의 공기가 누출되거나 다른 이유로 일정한 팽창력을 잃게되는 상태가 되면 압력계기(208)의 팽창력 감지선까지 원상회복시킬 수 있도록 신호를 중앙신호 처리장치(201)에 다시 보내게 되어, 에어콤프레셔(206)가 재차 작동되므로 인해 뒷좌석 공기주머니(19)에는 항시 일정한 양의 공기가 팽창 주입된 상태를 유지하고 있게 된다.Therefore, when the air in the rear seat air pocket 19 is leaked or loses a certain inflation force for other reasons, the signal is sent back to the central signal processor 201 to restore the inflation force to the inflation force detection line of the pressure gauge 208. As a result, since the air compressor 206 is operated again, the rear seat air pocket 19 is always kept inflated with a predetermined amount of air.
이와같은 상태에서 차량(K)은 운행중에 있을 때 타차량을 받거나 혹은 타차량으로 부터 받치게 되면 범퍼(L) 박만스위치(A)가 접지된다.In this state, when the vehicle K is in operation or receives another vehicle or is supported by the other vehicle, the bumper L thinning switch A is grounded.
이와같은 상황에 있을 때 부딪히는 대상물의 높고낮은 상태에 따라서 범퍼(L)의 유동이 발생되는데, 이와같은 추돌사고에 있어, 대상물이 높은 경우에는 상단부에 힘이 작용되므로 인해 범퍼(I)가 상향됨과 동시에, 범퍼를 고정한 힌지볼트(O)를 중심축으로 회동하게 된다.In this situation, the bumper (L) flows according to the high and low state of the object to be encountered. In such a collision accident, the bumper (I) is raised due to the force applied to the upper end when the object is high. At the same time, the hinge bolt O fixing the bumper is rotated about the central axis.
따라서, 받침범퍼가 상향될 때 고정축(P) 내측단부는 하향되면서 상,하의 일정한 텐숀을 유지하고 있던 스프링(Q)(Q')중 상부 스프링(Q')은 늘어나는 상태가 되고, 하부의 스프링(Q)은 압축되는 상태가 되며, 추돌된 대상물이 제차와 분리된 상태에 오게되면 스프링(Q)(Q')은 원래의 도면 제10도 상태가 된다.Therefore, when the supporting bumper is raised, the upper spring Q 'is extended among the springs Q'Q', which has maintained a constant tension of the upper and lower portions while the inner end of the fixed shaft P is lowered. The spring Q is in a compressed state, and when the collided object comes in a state separated from the vehicle, the spring Q 'is in the state of FIG. 10.
이렇게 추돌된 상태에서는 범퍼가 밀리는 상태가 되므로 인해 범퍼(L)가 고정되록 한 연결편(R)은 구부러짐과 동시에, 고정축(P)이 접지판(A1)을 타격하게 되어 단자(A2)와 접지하게 되고, 이에따른 신호는 신호처리장치(201)로 보내지게 되며, 받은신호는 동시에 밸브(202)를 개방시키게 하고, 유압펌프(203)를 작동시키며, 유압실린더(B)를 작동시켜주게 되므로서, 뒷등받이시트(104)가 뒤로(트렁크방향) 이동된다.In this collided state, the bumper is pushed, so that the connecting piece R to which the bumper L is fixed is bent, and the fixed shaft P strikes the ground plate A1 and the terminal A2 and the ground. As a result, the signal is sent to the signal processing device 201, and the received signal causes the valve 202 to be opened at the same time, the hydraulic pump 203 is operated, and the hydraulic cylinder B is operated. The backrest seat 104 is then moved backwards (trunk direction).
상기와 같이 뒷등받이시트(104)가 이동되는 상태를 좀더 구체적으로 설명하면 다음과 같다.The state in which the backrest seat 104 is moved as described above in more detail as follows.
추돌발생 시간으로 부터 뒷등받이시트(104)가 이동되기 까지는 거의 동시에 작동되며, 이와같은 순간작용은 오일의 점성을 높게하여 가능케 되는 것이며, 유압실린더(B)가 작동될 때 피스톤(G)은, 최초에 유압실린더(B)로 부터 빠져나와 있는 상태에 있으나. 유압펌프(203)가 작동됨에 따라 뒷등받이시트(104)를 이동시킬 때는 오므려지는 상태의 작동이므로 뒷등받이시트(104)를 이동시켜 주게 되는 것이다.From the time of collision, the backrest seat 104 is operated at about the same time. This momentary action is made possible by increasing the viscosity of the oil. When the hydraulic cylinder B is operated, the piston G is Initially, it is out of the hydraulic cylinder (B). As the hydraulic pump 203 is operated, the rear back seat seat 104 is moved when the rear back seat seat 104 is moved, thus moving the rear back seat seat 104.
상기 이동하는 뒷등받이시트(104)는 안내로울러(F)가 일측에 두개씩 양측에 설치되어 있고, 그 안내로울러(B)는 안내레일(D)에 삽입되어 있으므로, 피스톤(G)이 작용될 때 뒷등받이시트(104)가 용이하게 이동된다.The moving backrest seat 104 is provided with two guide rollers F on each side, and the guide roller B is inserted into the guide rail D, so that when the piston G is actuated, The backrest seat 104 is easily moved.
이와같이 뒷등받이시트(104)가 이동되는 동시에, 그 배면에 가진 뒷좌석 공기주머니(19)는 트렁크실격판(J)과의 사이에서 압압되면서, 내부의 공기는 고정덕트(18)와 연결덕트(7) 그라고, 전면의 등받이 시트(102)에 연결된 덕트(11)를 통하여 공기주머니(6)에 주입되므로, 도면 제1도에서 가상선으로 예시한 바와같이 풍선형태의 공기 주머니(6)를 형성하게 된다. 이때의 공기주머니(6)가 형성되는 상태를 구체적으로 설명하면 다음과 같다.As such, the back seat seat 104 is moved, and the rear seat air pocket 19 on the rear side is pressed between the trunk partition plate J, and the air inside is fixed duct 18 and the connection duct (7). In addition, since it is injected into the air bag 6 through the duct 11 connected to the backrest seat 102 of the front, to form a balloon-shaped air bag (6) as illustrated in the virtual line in FIG. do. The state in which the air bag 6 is formed will be described in detail as follows.
뒷좌석(103)의 뒷등받이시트(104)로 부터 이동된 공기가 전면 등받이시트(102)의 공기주머니(6)로 주입되는 시간은 거의 동시에 실시되며, 상기와 같이 공기주머니(6)가 형성되는 순간 덕트(11)는 덕트설치부(1)에서 분리되는 상태가 되며, 이와동시에 즉 공기가 주입되어 공기주머니(6)를 팽창시켜주는 작용에 따라 주머니 밴드(3)의 압력부(10)는 순간적인 힘이 작용하게 되어 절결되면서, 등받이 시트(102)로 부터 분리되어 풍선형태의 공기주머니(6)가 형성되는 것이다.The time that the air moved from the backrest seat 104 of the back seat 103 is injected into the air bag 6 of the front back seat 102 is carried out at about the same time, the air bag 6 is formed as described above The instantaneous duct 11 is in a state of being separated from the duct installation part 1, and at the same time, the pressure part 10 of the pocket band 3 according to the action of inflating the air bag 6 by injecting air is As the momentary force acts and is cut off, it is separated from the backrest seat 102 to form an air pocket 6 in the form of a balloon.
그리고, 상기 장치들은 설치하기 위해 차량(K)은 기종구조나 기능을 변경되지 않게 하기위해 앞좌석(101)의 승객체위 조절시 전,후 유동작동시에는 연결덕트(7)가 차실바닥(N)에 고정시킨 고정덕트(18)내부에 삽입된 상태에 슬라이딩 되도록 하였으며, 앞좌석(101)의 등받이시트(102)를 각도조절 목적으로 유동시킬 때에는 덕트(11)하단의 자바라 형성한 곳이 유동되도록 구성결합하였으므로, 구조가 간단하여 제작설치가 용이함과 동시에, 잎좌석(101)의 승객과 뒷좌석(103)의 탑승객을 추돌 교통사고에서 오는 충격을 최소화시켜 보호할 수 있게 되는 매우 유용한 고안인 것이다.In addition, the vehicle (K) for installation of the device in order not to change the structure or function of the front seat 101 in order to adjust the passenger position of the front and rear during the operation of the connection duct (7) is the vehicle floor (N) The sliding duct 18 is fixed to the inside of the fixed duct 18 so as to slide in the inserted state, and when the back seat 102 of the front seat 101 is flowed for angle adjustment purposes, the bellows formed at the bottom of the duct 11 flow. Since it is configured to combine, the structure is simple and easy to manufacture and installation, at the same time it is a very useful design that can protect the passengers of the leaf seat 101 and the passengers of the back seat 103 by minimizing the impact from collision traffic accidents .
