본 고안은 접점을 갖는 시트벨트 버클에 관한 것으로서, 특히 시트벨트 버클의 잠금/해제 작동상태에 따라 접속/단락되는 접점을 구비하여 시트벨트의 착용여부를 검지할 수 있게 함으로써, 탑승자가 있는 경우에만 승객용 에어백이 작동되게 한 접점을 갖는 시트벨트 버클에 관한 것이다.The present invention relates to a seat belt buckle having a contact, in particular, having a contact that is connected / shorted according to the locking / unlocking operation state of the seat belt buckle, so that the seat belt can be detected whether or not there is a passenger. A seat belt buckle having a contact for operating a passenger air bag.

일반적으로 대부분의 차량에 설치되어 있는 에어백 특히, 승객용 에어백은 차량 전면충돌시의 충격이 검지되면 시트 착석 여부에 관계없이 즉, 시트 착석자가 없어도 작동되도록 되어 있는 바, 이와같은 에어백은 한번 작동되면 재생 불가능하고, 또 고가여서 운전자에게는 적지 않은 부담을 주어 왔다.In general, airbags installed in most vehicles, especially passenger airbags, are designed to operate regardless of seat seating, i.e. without seat occupants, when an impact during a front collision is detected. It was not reproducible and expensive, and it has given a considerable burden to the driver.

따라서, 본 고안은 이와 같은 점을 감안하여 안출한 것으로서, 시트에 승객이 착석했는지의 여부를 시트벨트 착용에 따른 버클의 잠금/해제 작동상태를 이용하여 검지하고, 이때의 검지신호를 에어백 작동신호와 연계 접속시킴으로써, 불필요한 에어백의 오작동을 사전에 방지할 수 있게 한 접점을 갖는 시트벨트 벌클을 제공하는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above, and it is detected whether the passenger is seated on the seat using the lock / unlock operation state of the buckle according to the seat belt wearing, and the detection signal at this time is the airbag operation signal. It is an object of the present invention to provide a seat belt bulkhead having contacts which can prevent the malfunction of unnecessary airbags in advance.

이하, 첨부도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 미끄럼구배면(10)을 가지면서 전후방 탄력유동되는 누름체(11)와, 상기 누름체(11)의 구배면(10)에 미끄럼 접동되면서 상하방 탄력유동되는 걸림편(12)과, 상기 걸림편(12)의 상하방운동을 안내하는 가이드체(13) 및 하방유동을 단속하면서 후면 탄성 지지되는 찬단편(14)과, 전방 개구부(15)를 가지면서 이것들을 감싸고 있는 하우징(16)으로 구성된 시트벨트 버클에 있어서, 상기 누름체(11)의 후단 저면에는 가동접점(C1)이 부착 형성되고, 가동접점(C1)의 저부에는 일정한 전후 거리차를 가지면서 하우징 후벽면(17)에 일단 지지되는 고정접점(C2)이 위치되어서 이루어진 것이다.The present invention has a sliding body (11) having a sliding slope surface 10 and the front and rear elastic fluid sliding, and sliding the upper and lower elastic fluid sliding sliding on the gradient surface 10 of the pressing body (11) and The housing having the guide piece 13 for guiding the up and down movement of the locking piece 12 and the cold piece 14 which is elastically supported on the rear side while intermittent the downward flow, and the front opening 15, 16. In the seat belt buckle composed of 16), the rear contact bottom of the press body 11 is formed with a movable contact C1 attached thereto, and the rear part of the housing rear wall 17 having a constant front and rear distance difference at the bottom of the movable contact C1. The fixed contact (C2) once supported in the) is made.

특히, 상기 고정접점(C2)의 윗면은 가동접점(C1)의 밑면과 동일선상의 높이를 갖거나 적어도 그 이상의높이를 갖게 되므로서, 상호간의 접속가능한 구조가 이루어지게 된다.In particular, the upper surface of the fixed contact (C2) has the same line height as the bottom of the movable contact (C1) or at least the height, so that the structure can be connected to each other.

이를 좀더 상세히 설명하면, 첨부도면은 본 고안에 따른 시트벨트 버클(19)의 구조를 나타내는 측단면도로서, 상기 누름체(11)의 후단부에는 하우징 후벽면(17)에 일단 지지되는 스프링(18)의 다른 일단이 연결되어 있어서, 항상 안쪽으로 당겨지는 탄성력을 받게 되고, 가이드체(13) 내에서 상하 유동되는 걸림편(12)과의 미끄럼 접동을 통해서 전방으로 일정거리 유동될 수 있게 된다. 즉, 상기 걸림편(12)의 하향 유동을 단속하고 있는 차단편(14)이 버클(19)에 체결되는 텅(20)(TONGUE)에 의해 밀려나면서 걸림편(12)의 단속상태가 해제되면, 이와동시에 걸림편(12)이 하향 유동되면서 누름체(11)를 전방으로 밀어내게 된다. 이때의 누름체(11)의 후단부에 수직하향 형성되어 있는 가동접점(C1)은 누름체(11)의 전방이동시 이와함께 이동되어 후술하는 그 앞쪽의 고정접점(C2)과 접속될 수 있게 된다.To explain this in more detail, the accompanying drawings are side cross-sectional views showing the structure of the seat belt buckle 19 according to the present invention, the rear end of the pressing body 11 is a spring 18 once supported on the housing rear wall surface 17 Since the other end of the) is connected, it is always subjected to an elastic force pulled inward, it is possible to flow a certain distance forward through the sliding sliding with the locking piece 12 that is vertically flow in the guide body (13). That is, when the interrupting state of the locking piece 12 is released while the blocking piece 14 which is interfering with the downward flow of the locking piece 12 is pushed by the tongue 20 fastening to the buckle 19, the locking piece 12 is released. At the same time, as the locking piece 12 flows downward, the pressing body 11 is pushed forward. At this time, the movable contact (C1) is formed in the rear end of the pressing body 11 in the vertical direction is moved along with this when the front body of the pressing body 11 can be connected to the fixed contact point (C2) of the front that will be described later .

한편, 상기 가동접점(C1)의 저부에는 하우징 후벽면(17)에 일단 지지되면서 앞쪽으로 수평연장되는 고정접점(12)이 위치된다. 이때, 고정접점(C2)의 선단 접점면(P2)은 상기한 가동접점(C1)의 직하방 위치보다 일정거리 앞쪽에 위치되게 되는 동시에 가동접점(C1)의 하단 접점면(P1) 높이와 동일한 높이를 갖게 되거나 그 보다 좀더 높은 높이를 갖게 되므로서, 상기 두 접점면(P1),(P2)간의 접속이 가능하게 된다.On the other hand, at the bottom of the movable contact (C1) is a fixed contact 12 which is horizontally extended forward while being supported by the housing rear wall surface 17 is located. At this time, the tip contact surface (P2) of the fixed contact (C2) is positioned a certain distance ahead of the direct downward position of the movable contact (C1) and at the same time the height of the bottom contact surface (P1) of the movable contact (C1). Since the height is higher or higher, the connection between the two contact surfaces P1 and P2 is possible.

따라서 첨부도면의 (A)에서와 같이 시트벨트버클(19) 내에 텅(20)이 체결되어 있지 않은 상태에서는 누름체(11)가 최대한 안쪽으로 당겨진 상태로 위치되므로 상기 두 접점(C1),(C2)은 상호 단락상태를 유지하게 되고, 이때에는 승객용 에어백의 작동이 이루어지지 않게 된다.Therefore, in the state in which the tongue 20 is not fastened in the seat belt buckle 19 as shown in (A) of the accompanying drawings, since the pressing body 11 is positioned to be pulled inward as far as possible, the two contacts C1, ( C2) is maintained in a short circuit state, at which time the operation of the passenger airbag is not made.

이와는 달리 탑승자가 시트 착석과 동시에 하우징(16)의 개구부(15)를 통하여 텅(20)을 삽입하게 되면, 이텅(20)의 끝단부에 의해 차단편(14)이 안쪽으로 밀려나면서 여기에 저지되어 있던 가이드체(13) 내의 걸림편(12)이 하방이동되고, 이와 함께 구배면(10)과의 접동을 통해 누름체(11)를 바깥쪽으로 밀어내게 된다. 이렇게 누름체(11)가 이동되면 그 후단 가동접점(C1)의 접접면(P1)과 고정접점(C2)의 접접면(P2)은 서로 밀착되면서 접속상태를 유지하게 되고, 이때에는 승객용 에어백의 작동이 이루어질 수 있게 된다.On the other hand, when the occupant inserts the tongue 20 through the opening 15 of the housing 16 at the same time as the seat is seated, the blocking piece 14 is pushed inward by the end of the tooth 20 and is blocked there. The engaging piece 12 in the guide body 13 which has been made is moved downward, and pushes the press body 11 outward through sliding with the gradient surface 10 at the same time. When the pressing body 11 is moved in this way, the contact surface P1 of the rear end movable contact C1 and the contact surface P2 of the fixed contact C2 are kept in close contact with each other. In this case, the passenger airbag The operation of can be made.

이상에서와 같이 시트벨트 버클의 내부에 접점을 형성하고, 상기 두 접점은 시트벨트 버클에 텅이 체결됨과 동시에 즉, 시트 착석자가 시트벨트를 착용함과 동시에 상호접속되게 하여 승객용 에어백을 작동 가능한 상태로 유지할 수 있으므로써, 승객용 에어백의 불필요한 오작동을 사전에 방지할 수 있는 장점이 있는 것이다.As described above, a contact point is formed inside the seat belt buckle, and the two contact points are connected to the seat belt buckle at the same time, that is, the seat occupant is interconnected at the same time as the seat belt is worn by the passenger. By maintaining the state, there is an advantage of preventing unnecessary malfunction of the passenger airbag in advance.
