도 1은 본 발명에 따른 에어백과 연동되는 차량용 페달이 장착된 차량의 사시도를 도시한 것인바, 본 발명은 크러시 패드(C)의 하부로 위치된 족동식 주차브레이크 페달(1)이 차량의 에어백(A)시스템의 제어기(T)에 연결되어 작동되되, 상기 페달(1)은 릴리이즈케이블과 연결됨과 더불어 운전자의 조작시 작동되도록 기구적으로 이루어진 작동어셈블리(2)에 돌출된 어퍼부재(3)와, 이 어퍼부재(3)에 슬라이딩 되도록 결합된 로워부재(4), 이 부재(3,4)들 사이에 형성된 홀에 삽입된 이동축(5a)을 구비한 조작수단(5) 및 상기 로워부재(4)를 어퍼부재(3)내로 삽입시키기 위한 탄성력을 발생하는 탄성수단(6)으로 이루어진다.1 is a perspective view of a vehicle equipped with a vehicle pedal that is interlocked with an airbag according to the present invention, the present invention is a foot-type parking brake pedal (1) located below the crush pad (C) airbag of the vehicle (A) the upper member (3) which is connected to the controller (T) of the system and operated, wherein the pedal (1) is connected to the release cable and protrudes into the operating assembly (2) mechanically configured to be operated when the driver operates. And a lower member 4 coupled to the upper member 3 so as to slide, an operating means 5 having a moving shaft 5a inserted into a hole formed between the members 3 and 4, and the lower. It consists of elastic means 6 for generating an elastic force for inserting the member 4 into the upper member 3.

여기서, 상기 어퍼·로워부재(3,4)는 슬라이딩되도록 서로 결합되되, 도 3에 도시된 바와 같이 상기 로워부재(4)가 어퍼부재(3)의 안 쪽으로 위치되어짐은 물론이다.Here, the upper and lower members 3 and 4 are coupled to each other so as to slide, and as shown in FIG. 3, the lower member 4 is positioned inward of the upper member 3.

그리고, 상기 로워부재(4)는 크러시 패드(C)의 수직선상인 크러시패드위치(L)에 비해 페달돌출위치(L1)까지 돌출 되어진다.In addition, the lower member 4 protrudes up to the pedal protrusion position L1 as compared to the crush pad position L which is in the vertical line of the crush pad C.

또한, 상기 조작수단(5)은 에어백시스템의 제어기(T)신호를 입력받아 작동되는 솔레노이드로 이루어져 차량용 배터리로부터 전원을 공급받아 작동되도록 전기회로(도시되어 있지 않음)를 구성함은 물론이다.In addition, the operation means 5 is composed of a solenoid that is operated by receiving the controller (T) signal of the airbag system is configured of an electric circuit (not shown) to operate by receiving power from the vehicle battery.

그리고, 상기 탄성수단(6)은 그 일측이 어퍼부재(3)의 내측에 고정되고 그 타측이 로워부재(4)의 내측에 고정되는 스프링으로 이루어지되, 이 스프링은 서로 간격을 두고 2개가 구비됨은 물론이다.And, the elastic means 6 is made of a spring whose one side is fixed to the inside of the upper member 3 and the other side is fixed to the inside of the lower member 4, the spring is provided with two at intervals Of course.

이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

차량의 충돌이 발생하여 에어백시스템의 제어기(T)로 충격량에 따른 전기적 신호가 입력되면, 이 제어기(T)의 내장된 프로그램에 따라 처리된 전기적 신호가 조작수단(5)으로 전송되어진다.When a collision of the vehicle occurs and an electrical signal corresponding to the amount of impact is input to the controller T of the airbag system, the electrical signal processed according to the built-in program of the controller T is transmitted to the operation means 5.

이에 따라, 상기 제어기(T)의 신호를 받은 조작수단(5)의 솔레노이드는 전원이 통전되어져 상기 어퍼·로워부재(3,4)를 고정한 이동축(5a)을 후퇴(도 3의 화살표방향)시켜 주게 되고, 이오 인해 상기 어퍼부재(3)와 로워부재(3)에 고정된 탄성수단(6)인 스프링이 원래위치로 복원되면서 로워부재(4)를 어퍼부재(3)쪽으로 이동시키게 된다.Accordingly, the solenoid of the operation means 5 receiving the signal from the controller T retracts the moving shaft 5a on which the upper and lower members 3 and 4 are fixed by supplying power (arrow direction in Fig. 3). Due to this, the spring, which is the elastic means 6 fixed to the upper member 3 and the lower member 3, is restored to its original position, thereby moving the lower member 4 toward the upper member 3.

즉, 도 4에 도시된 바와 같이 조작수단(5)의 이동축(5a)에 의해 탄성수단(6)을 강제로 인장시킨 상태로 어퍼부재(3)로부터 인출된 로워부재(4)가 상기 이동축(5a)의 후퇴와 함께 탄성수단(6)의 복원력에 의해 어퍼부재(3)쪽으로 빠르게 이동되어 페달돌출위치(L1)를 크러시패드위치(L)의 안쪽으로 위치시키게 된다.That is, as shown in FIG. 4, the lower member 4 withdrawn from the upper member 3 in the state in which the elastic means 6 is forcibly tensioned by the moving shaft 5a of the operating means 5 is moved. With the retreat of the shaft 5a, the restoring force of the elastic means 6 moves rapidly toward the upper member 3, thereby positioning the pedal protrusion position L1 inward of the crush pad position L.

이에 따라, 충격력에 의해 크러시 패드(C)쪽으로 위치되는 인체정강이부(H)가 페달(1)의 로워부재(4)와 부딪히지 않게 되므로 결국, 페달(1)에 의한 손상을방지하게 됨은 물론이다.Accordingly, the human shin portion (H) located toward the crush pad (C) by the impact force does not collide with the lower member (4) of the pedal (1), after all, of course to prevent damage by the pedal (1) .

이상 설명한 바와 같이 본 발명에 의하면, 차량의 충돌 시 이를 감지하는 에어백의 작동 신호에 연동되어 페달의 길이를 크러시 패드의 수직선상 안 쪽으로 위치되도록 줄여 관성력에 의해 이동되는 운전자의 인체정강이부의 손상을 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, in response to the operation signal of the airbag that detects the collision of the vehicle to reduce the length of the pedal to be located in the vertical line of the crush pad to prevent damage to the driver's body shin portion by the inertial force It will work.
