본 발명은 차량의 시트벨트 웨빙 구속장치에 관한 것으로, 특히 차량의 충돌시에 시트벨트를 착용한 착석자의 신체가 진행방향으로 쏠림에 따라 시트벨트의 웨빙이 당겨져서 풀려질 때에 이를 효과적으로 저지하여 착석자를 보다 안전하게 보호할 수 있도록 된 차량의 시트벨트 웨빙 구속장치에 관한 것이다.The present invention relates to a seat belt webbing restraint device of a vehicle, in particular, when the body of the seat belt wearing the seat belt is slid in the direction of travel during the collision of the vehicle, when the webbing of the seat belt is pulled and released, the seat is effectively restrained and seated. It relates to a seat belt webbing restraint device for a vehicle that can protect the ruler more safely.

일반적으로 차량에는 승객이 탑승해서 안락한 승차감을 느낄 수 있도록 차실내부의 전후방으로 시트가 장착되어 있는 바, 이와같이 승객이 차량에 탑승하여 시트에 착석할 경우에 차량의 주행중에 발생될 수 있는 여러가지 위험으로부터 승객을 안전하게 보호하기 위해 각 시트에는 통상적으로 시트벨트가 구비되어 있다.In general, the vehicle is equipped with seats in the front and rear of the cabin to allow passengers to feel comfortable riding, and thus, from the various dangers that may occur during the driving of the vehicle when the passenger is seated on the seat. Each seat is typically equipped with a seat belt to protect the passengers.

상기와 같은 종래의 시트벨트는 차실내의 좌/우측 하단부에 고정되어 웨빙을 탄력적으로 감아 수용하는 리트렉터와, 이 리트텍터로부터 인출된 웨빙을 좌/우측 트림부에 걸어주는 행거, 이 행거를 통과한 웨빙에 섭동가능하게 끼워진 텅부재, 이 텅부재와 착탈가능하게 결합되어 웨빙이 탑승자의 신체를 가로지르는 방향으로 배열될 수 있도록 고정시켜주는 버클로 구성되어 있다.The conventional seat belt as described above is a retractor fixed to the lower left and right lower ends of the vehicle cabin and elastically wound and accommodated the webbing, a hanger that hangs the webbing drawn from the retractor to the left and right trim, and the hanger Tongue member removably fitted to the passing webbing, and a buckle that is detachably coupled to the tongue member to fix the webbing to be arranged in a direction crossing the occupant's body.

따라서 시트에 앉은 승객은 상기 리트렉터로부터 신장되어 행거를 거친 웨빙에 끼워진 텅부재을 자신의 가슴부위로 지나도록한 다음 시트의 측부에 고정된 버클에 체결시키게 되면, 착석자의 신체가 상기 웨빙에 의해 시트로부터 이탈되지 못하도록 지지되게 있다.Thus, when a passenger sitting on the seat passes the tongue member, which is extended from the retractor and fitted into the webbing through the hanger, passes through his chest, and is fastened to a buckle fixed to the side of the seat, the body of the seated person is seated by the webbing. To be supported so as not to depart from it.

그러나 상기와 같은 종래의 시트벨트에서 그 리트렉터는 웨빙을 감아주고 있는 릴장치와, 차량의 충돌시에 웨빙이 일정길이 이상으로 풀려나가지 않도록 잡아주는 웨빙구속장치 및, 차량의 충돌시에 이를 감지해서 상기 웨빙구속장치를 작동시켜주는 감지장치 등으로 구성되어 있는 데, 이와 같은 종래의 리트렉터는 그 구조가 상당히 복잡하여 제작이 어려울 뿐만 아니라 차량의 제조단가를 상승시키는 원인이 되고 있었다.However, in the conventional seat belt as described above, the retractor is a reel device that winds up the webbing, a webbing restraint device that holds the webbing not to be released beyond a certain length in the event of a vehicle collision, and detects it when the vehicle crashes. Therefore, it is composed of a sensing device for operating the webbing restraint device. Such a conventional retractor has a complicated structure, which is difficult to manufacture, and also increases the manufacturing cost of the vehicle.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 구조가 간단하면서도 차량의 충돌시에 이를 감지해서 웨빙이 풀려나가는 것을 효과적으로 저지해 줌으로써 탑승자의 안전을 도모할 수 있도록 된 차량의 시트벨트 웨빙 구속장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned circumstances, and the seat belt webbing restraint of the vehicle which is simple in structure and effectively prevents the webbing from being released by the collision of the vehicle can be prevented from being released. The object is to provide a device.

상기한 바의 목적을 달성하기 위한 본 발명은, 시트벨트의 웨빙을 탄력적으로 감아주기 위해 스프링이 내장된 릴장치로부터 앵커를 통해 착석자의 신체쪽으로 연장되어 착석자의 신체를 구속해주는 웨빙이 전자석 고정로울러와 2개의 이동로울러사이를 통해 연장되고, 상기 전자석 고정로울러에는 차량의 밧데리 전원에 차체쏠림감지센터를 개재하여 연결된 릴레이를 매개로 전원을 선택적으로 일정시간 동안에 공급받도록 연결되며, 상기 2개의 이동로울러는 전자석 고정로울러의 축에 각각의 링크를 매개로 이동가능하게 연결되는 한편, 상기 링크의 각 외주에는 이동로울러를 원래의 위치로 복귀시켜 주는 복귀스프링이 끼워진 구조로 되어 있다.The present invention for achieving the above object, the webbing extending to the seated body of the seated through the anchor from the reel device with a spring to elastically wrap the webbing of the seat belt is fixed to the seated body of the electromagnet fixed roller And between the two moving rollers, and the electromagnet fixed roller is connected to receive power selectively for a predetermined time through a relay connected to the battery power of the vehicle via a body moving detection center, and the two moving rollers. Is connected to the shaft of the electromagnet fixed roller via a respective link, while each outer circumference of the link is fitted with a return spring for returning the moving roller to its original position.

이에 따라 차량의 충돌시에 상기 센서에 의해 감지된 신호에 따라 전원이 전자석 고정로울러로 공급되어 상기 2개의 이동로울러를 자력으로 당겨줌으로써, 이들 로울러사이에 웨빙이 끼여져 구속됨에 따라 착석자를 보다 안전하게 보호할 수 있을 뿐만 아니라 구조도 간단하여 제작단가를 저감시킬 수 있게 된다.Accordingly, the power is supplied to the electromagnet fixed roller according to the signal detected by the sensor at the time of the collision of the vehicle, and the two moving rollers are pulled by the magnetic force, so that the webbing is sandwiched between these rollers and restrained the seated person more safely. Not only can it be protected, but also its structure is simple, which can reduce the manufacturing cost.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 시트벨트 웨빙 구속장치가 센타필라에 장착된 상태의 개략적인 평면도이고, 제2도는 본 발명에 따른 시트벨트 웨빙 구속장치가 작동되기 이전 상태의 제1도의 A-A선 단면도인 바, 즉 시트벨트의 웨빙(1)을 탄력적으로 감아주기 위해 스프링이 내장된 릴장치(2)와, 이 릴장치(2)로부터 앵커(3)를 통해 착석자의 신체쪽으로 연장되어 착석자의 신체를 구속해주는 웨빙(1)이 차량의 충돌시에 착석자를 보호하기 위해 릴장치로부터 풀려나가지 않도록 구속해주는 구속수단 및, 차량의 충돌시에 이를 감지해서 상기 구속수단을 작동시켜주는 감지수단을 갖춘 구조로 되어 있다.FIG. 1 is a schematic plan view of the seat belt webbing restraint device according to the present invention mounted on the center pillar, and FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 before the seat belt webbing restraint device according to the present invention is operated. A reel device (2) with a spring to reel the webbing (1) of the seat belt elastically, and extends from the reel device (2) toward the seated body of the seater through the anchor (3). It has a structure with a restraining means for restraining the webbing (1) restraining from being released from the reel device to protect the occupant in the event of a vehicle collision, and a sensing means for detecting this in the event of a vehicle collision and operating the restraining means. It is.

여기서 상기 감지수단은 예컨대 차량의 밧데리 전원에 차체쏠림감지센서(4)가 연결되면서 이 센서(4)는 릴레이(5)를 개재하여 상기 구속수단에 연결된 구조로 되어 있다.In this case, the sensing means is connected to the restraining means, for example, while the vehicle body tilt sensing sensor 4 is connected to the battery power source of the vehicle via the relay 5.

이에 따라 차량의 충돌시에 상기 센서(4)에 의해 신호가 감지되면, 밧데리 전원이 센서(4)를 통해서 릴레이(5)에 공급됨과 더불어 이 릴레이(5)를 통해서 전원이 일정시간 동안에 상기 구속수단으로 공급되게 된다.Accordingly, when a signal is detected by the sensor 4 at the time of collision of the vehicle, battery power is supplied to the relay 5 through the sensor 4 and power is restrained for a predetermined time through the relay 5. To be supplied by means.

그리고 상기 구속수단은 상기 릴레이(5)를 통해 일정시간 동안에 전원을 공급받아 자화되어 자력을 발생시키는 전자석 고정로울러(6)와 이 전자석 고정로울러(6)의 축에 각각의 링크(7a,8a)를 매개로 이동가능하게 연결된 제1, 2 이동로울러(7,8) 및, 상기 링크(7a,8a)의 각 외주에 끼워진 복귀스프링(9)을 갖추는 한편, 상기 전자석 고정로울러(6)와 2개의 이동로울러(7,8)사이를 통해 상기 웨빙(1)이 연장되게 되어 있다.The restraining means is supplied with power through the relay 5 for a predetermined time and is magnetized to generate magnetism, and the respective links 7a and 8a are connected to the shaft of the electromagnet fixed roller 6. First and second moving rollers 7 and 8 movably connected via a second and return springs 9 fitted to respective outer circumferences of the links 7a and 8a, respectively, and the electromagnet fixed rollers 6 and 2 The webbing 1 extends between the two moving rollers 7, 8.

이하 본 발명에 따른 차량의 시트벨트 웨빙 구속장치의 작용 및 효과를 설명한다.Hereinafter will be described the operation and effect of the seat belt webbing restraint device of the vehicle according to the present invention.

차량의 주행중에 다른 차량과 충돌되면 상기 센서(4)가 이를 감지함과 더불어 이 감지신호로 전원이 릴레이(5)를 통해 상기 전자석 고정로울러(6)에 일정시간 동안 공급되게 되고, 이에 따라 전자석 고정로울러(6)는 자화되어 자력을 발생시키게 된다.When the vehicle collides with another vehicle while the vehicle is driving, the sensor 4 detects this, and power is supplied to the electromagnet fixed roller 6 through the relay 5 for a predetermined time by the detection signal. The fixed roller 6 is magnetized to generate magnetic force.

그리고 상기 전자석 고정로울러(6)에서 발생된 자력으로 상기 2개의 이동로울러(7,8)들은 각각의 링크(7a,8a)에 끼워진 상태로 링크(7a,8a)를 따라서 제3도에 도시된 바와 같이 상기 전자석 고정로울러(6)쪽으로 당겨지게 되어, 이들 로울러 사이를 통해 연장되는 웨빙(1)이 로울러들 사이에 끼여서 잡혀지게 되므로, 상기 웨빙(1)에 걸쳐져 있는 착석자의 신체가 차량의 진행방향으로 쏠리게 되는 것을 효과적으로 저지하여 탑승자를 보다 안전하게 보호해주게 된다.And the two moving rollers (7, 8) by the magnetic force generated in the electromagnet fixed roller (6) is shown in Figure 3 along the links (7a, 8a) in the state fitted to each of the links (7a, 8a) As it is pulled toward the electromagnet fixed roller 6, the webbing 1 extending between these rollers is caught between the rollers, so that the body of the seated person seated over the webbing 1 travels. This effectively prevents the vehicle from tipping in the direction, making it safer for the occupants.

한편 상기 전자석 고정로울러(6)에 공급되는 전원은 릴레이(5)를 통해 일정시간 동안만 공급되게 되는 데, 일정시간이 경과된 후에는 전자석 고정로울러(6)에 공급되는 전원이 릴레이(5)에 의해 차단되게 되고, 이에 따라 전자석 고정로울러(6)에서 자력이 소멸됨과 더불어 상기 복귀스프링(9)의 탄성복원력으로 각 링크(7a,8a)들은 원래의 위치로 밀려져 복귀되어, 로울러들사이의 간격이 충분하게 벌어짐에 따라 상기 웨빙(1)이 제2도에 도시된 상태와 같이 로울러들 사이를 통해 자유로이 이동될 수 있게 됨으로써, 착석자는 시트벨트를 임의로 조절할 수 있게 되는 것이다.On the other hand, the power supplied to the electromagnet fixed roller 6 is to be supplied only for a predetermined time through the relay (5), after a predetermined time has passed the power supplied to the electromagnet fixed roller (6) the relay (5) By the magnetic force is eliminated in the electromagnet fixed roller (6), and the link (7a, 8a) is pushed back to its original position by the elastic restoring force of the return spring (9), between the rollers As the spacing of the gap is sufficiently wide, the webbing 1 can be freely moved between the rollers as shown in FIG. 2, so that the seater can arbitrarily adjust the seat belt.

이상 설명한 바와 같이 본 발명에 따른 차량의 시트벨트 웨빙 구속장치에 의하면, 차량이 주행중에 충돌되면 이를 감지해서 착석자의 신체를 지지해주는 웨빙이 풀려나가지 않도록 구속해줌으로써, 착석자를 보다 안전하게 보호해줄 수 있을 뿐만 아니라 구조도 간단하여 제조단가를 낮출 수 있는 효과가 있다.As described above, according to the seat belt webbing restraint apparatus for a vehicle according to the present invention, when the vehicle collides while driving, the seat belt webbing restraint device can detect the restraint and restrain the webbing supporting the body of the seat occupant so that the seat occupant can be protected more safely. In addition, the structure is simple, there is an effect that can lower the manufacturing cost.
