본 발명은 차량용 안전벨트의 텅플레이트완퉁장치에 관한 것으로 보다 상세하게는 텅플레이트에 충격흡수부가 구비되어 자동차의 급제동이나 충돌에 따른 탑승객의 충격을 완화할 수 있도록 된 차량용 안전벨트의 텅플레이트완충장치에 관한 것이다.The present invention relates to a tongue plate bumping device of a vehicle seat belt, and more particularly, a tongue plate buffering device of a vehicle seat belt provided with a shock absorbing part on a tongue plate to mitigate the impact of a passenger due to sudden braking or a collision of a vehicle. It is about.

일반적으로, 자동차의 실내에는 탑승객의 안전을 보장하기 위하여 안전벨트가 설치되어 있고, 이러한 안전벨트에서 탑승객이 착용하는데 필요한 텅플레이트가 구비되어 있다.In general, a seat belt is installed in the interior of a vehicle to ensure the safety of the passenger, and a tongue plate necessary for the passenger to wear in the seat belt is provided.

제1도에 도시된 바와 같이, 종래의 텅플레이트는 체결구(101)를 하우징(102)이 감싸고 있고, 이러한 하우징의 하단부에는 안전벨트가 통과될 수 있는 안전벨트 연결공(102a)이 구비되어 있다.As shown in FIG. 1, the conventional tongue plate has a housing 102 wrapped around the fastener 101, and the lower end of the housing is provided with a seat belt connecting hole 102a through which the seat belt can pass. have.

상기와 같이 구성된 종래의 텅플레이트(100)는 차량이 급제동 또는 충돌될 때 탑승객의 신체가 앞으로 쏠리면서 안전벨트에 충격이 가해지게 되고 이러한 충격은 하우징(102)을 거쳐 버클(Buckle)에 체결되어 있는 체결구(101)에 작용하게 된다.In the conventional tongue plate 100 configured as described above, when the vehicle is suddenly braked or crashed, the passenger's body is moved forward and an impact is applied to the seat belt. Such an impact is fastened to a buckle through the housing 102. Acting on the fastener 101.

그러나, 상기와 같은 종래 차량용 안전벨트의 텅플레이트는 차량이 급제동되거나 충돌될 경우, 체결구(101)와 하우징(102)이 별도의 충격흡수수단 없이 일체로 성형되어 있으므로 안전벨트가 탑승객의 신체에 무리한 압박을 가하게 되는 문제점이 있었다.However, the tongue plate of the seat belt of the conventional vehicle as described above, when the vehicle is suddenly braked or collided, since the fastener 101 and the housing 102 are integrally molded without a separate shock absorbing means, the seat belt is on There was a problem of applying excessive pressure.

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 차량의 급제동 또는 충돌에 따른 안전벨트가 탑승객의 신체에 가하는 충격력을 완화시키도록 된 차량용 안전벨트의 텅플레이트를 제공함에 그 목적이 있다.An object of the present invention is to provide a tongue plate of a seat belt for a vehicle, which is designed to mitigate the impact force applied to the body of a passenger due to a sudden braking or crash of the vehicle.

상기한 목적을 달성하기 위하여 본 발명은 버클에 체결되는 체결구와 일체로 성형된 상부 하우징과, 벨트 연결공을 구비한 하부 하우징, 상기 상부 하우징과 하부 하우징 사이에 고정용 리벳을 매개로 절곡연결된 스틸플레이트를 포함하여 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention is an upper housing integrally formed with a fastener fastened to a buckle, a lower housing having a belt connection hole, and steel bent and connected through fixing rivets between the upper housing and the lower housing. It has a structure including a plate.

이와 같이 본 발명의 텅플레이트완충장치는 차량이 급제동하거나 충돌될 때 상부 하우징과 하부 하우징의 사이의 스틸플레이트가 펼쳐지면서 충격력을 흡수하게 된다.As described above, the tongue plate buffering device of the present invention absorbs the impact force while the steel plate is unfolded between the upper housing and the lower housing when the vehicle is suddenly braked or collided.

따라서, 스틸플레이트가 안전벨트의 탑승객을 구속하는 힘을 흡수함으로써 탑승객은 안전벨트에 의해서 발생되는 상해를 보호받게 되는 것이다.Thus, the steel plate absorbs the force restraining the occupant of the seat belt, so that the occupant is protected from the injury caused by the seat belt.

이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

제2도는 본 발명에 따른 차량용 안전벨트의 텅플레이트를 도시한 사시도이고, 제3도(a)는 본 발명에 따른 차량용 안전벨트의 텅플레이트의 단면도이다.2 is a perspective view showing a tongue plate of a vehicle seat belt according to the present invention, and Figure 3 (a) is a cross-sectional view of the tongue plate of a vehicle seat belt according to the present invention.

본 발명에 따른 안전벨트의 텅플레이트는 제2도에 도시된 바와 같이, 버클에 체결되는 체결구(11)와 일체로 성형된 상부 하우징(12)과, 벨트 연결공(15a)을 구비한 하부 하우징(15), 상기 상부하우징(12)과 하부 하우징(15) 사이에 고정용 리벳(13)을 매개로 절곡연결된 스틸플레이트(14)를 포함하여 이루어진 구조로 되어 있다.The tongue plate of the seat belt according to the present invention, as shown in Figure 2, the lower part having an upper housing 12 formed integrally with the fastener 11 is fastened to the buckle, and the belt connection hole 15a The housing 15, the upper housing 12 and the lower housing 15 has a structure consisting of a steel plate 14 bent connected via a fixing rivet 13 as a medium.

제3도 (a)를 참조하여 설명하면, 상기 체결구(11)는 상부 하우징(12)에 일측선단이 삽입되어 고착되어 있고, 자유단에는 버클에 결합되는 결합홈(11a)이 형성되어 있다.Referring to Figure 3 (a), the fastener 11 is fixed to the one end is inserted into the upper housing 12, the coupling end 11a is coupled to the buckle at the free end is formed. .

상기 스틸플레이트(14)는 일단이 상부 하우징(12)의 하단면에 고정되고, 타단이 하부 하우징(15)의 상단면에 고정되면서 절곡되어 중앙부가 상,하부 하우징(12,14) 면사이에서 고정용 리벳(13)으로써 고정부착되어 있다.The steel plate 14 has one end fixed to the bottom surface of the upper housing 12, the other end is bent while being fixed to the top surface of the lower housing 15, the center portion between the upper, lower housing 12, 14 surface It is fixed and fixed by the fixing rivet 13.

물론, 스틸플레이트(14)는 소정의 길이로 탄성을 지는 얇은 판형상으로 되어 일정치 이상의 충격을 받으면 펼쳐지도록 되어 있다.Of course, the steel plate 14 is made into a thin plate shape that is elastic to a predetermined length, and is to be unfolded when subjected to a predetermined value or more.

제3도 (b)를 참조하여 안전벨트의 텅플레이트에 충격이 가해진 후에 상태를 설명하면, 차량이 급제동하거나 충돌할 경우 상부 하우징(12)과 하부 하우징(15) 사이에 고정설치된 스틸플레이트(14)가 일차적으로 충격을 부담하게 되고, 한계충격을 초과하는 충격이 가해질 때에 상,하부 하우징(12,14)에 스틸플레이트(14)를 고정하는 고정용 리벳(13)이 분리되면서 스틸플레이트(14)가 펼쳐지게 된다.Referring to FIG. 3 (b), after the shock is applied to the tongue plate of the seat belt, the steel plate 14 fixed between the upper housing 12 and the lower housing 15 when the vehicle suddenly brakes or collides. ) Is primarily a shock, and when the impact exceeding the limit shock is applied to the upper and lower housings 12 and 14, the fixing rivet 13 for fixing the steel plate 14 is separated and the steel plate 14 ) Will be unfolded.

즉, 스틸플레이트(14)는 양단은 상부 하우징(12)의 하단면과 하부 하우징(14)의 상단면에 고정된 상태로 길이가 늘어나면서 충격을 흡수하게 되는 것이다.That is, both ends of the steel plate 14 are absorbed from the shock while the length thereof is fixed to the lower end surface of the upper housing 12 and the upper end surface of the lower housing 14.

이상에서 설명한 바와 같은 본 발명의 이와 같이 구성된 본 발명에 의한 차량용 안전벨트의 텅플레이트완충장치는 차량이 급제동하거나 충돌될 경우, 스틸플레이트가 펼쳐지면서 충격을 흡수하게 되어 안전벨트를 착용하고 있는 탑승객에게 작용하는 충격력을 흡수함으로써 탑승객이 상해를 입지 않고 안전하게 보호되는 것이다.As described above, the tongue plate buffering device of the seat belt for a vehicle according to the present invention configured as described above absorbs an impact while the steel plate is unfolded when the vehicle is suddenly braked or collided, so that the passenger wearing the seat belt By absorbing the impact force, passengers are protected without injury.
