차량의 도어글라스Door glass of the vehicle

본 발명은 차량의 도어글라스에 관한 것으로서, 보다 상세하게는 차량 충돌시 도어글라스의 내측면에 소정의 부피팽창하는 완충재를 구성하여 탑승객의 머리부를 보호할 수 있는 차량의 도어글라스에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass of a vehicle, and more particularly, to a door glass of a vehicle capable of protecting a head of a passenger by configuring a predetermined volume-expanded cushioning material on the inner surface of the door glass during a vehicle collision.

일반적으로 자동차의 충돌 사고시 승객의 안전성을 확보하기 위한 테스트로는 전방충돌과 측면충돌이 있으며, 이는 자동차의 충돌 사고시 승객의 안전성을 확보하는 중요한 요소로서, 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 항목으로 이용하고 있다.In general, tests to ensure passenger safety in the event of a car crash include front and side collisions, which are important factors to secure passenger safety in the event of a car crash. It is used for items such as import regulation.

실제로 차량 전후방에는 외부 충돌에 대한 충격 저감수단으로 우레탄 등의 완충부재로 성형된 범퍼 등을 설치하여 충돌에너지에 대응하고 있으며, 또한 차실측에는 운전석 및 조수석의 전방측에 차량 충돌시 순간적으로 부피팽창하여 탑승자의 부상을 최소한도로 줄이는 에어백이 설치되어 있지만, 측면충돌에 대해서는 별다른 충격 저감수단이 없는 것이 현실이다.In fact, bumpers made of shock absorbing members, such as urethane, are installed at the front and rear of the vehicle to reduce impact against external collisions, and respond to collision energy on the vehicle side. Air bags are installed to minimize the injuries of the occupants, but the reality is that there is no impact reduction means against side collisions.

이는 현재 차량의 측면에 설치할 수 있는 충격 저감수단은 부피나 무게에 따른 연비상승 등 많은 조건을 고려하여 제한적으로 설치되므로, 그 효과가 탑승자를 안전하게 보호하기에는 미흡한 것이 문제점으로 노출되어 왔다.This is because the impact reduction means that can be installed on the side of the current vehicle is limited in consideration of many conditions, such as fuel economy increase according to volume or weight, the effect has been exposed to the problem that the effect is insufficient to protect the occupants safely.

그러므로 상기 종래의 차량은 측면충돌시 충돌력에 대한 적절한 강성을 보유하지 못하였으므로 상당한 충격력이 차실에 위치된 탑승객에게 전가되는 현상이 있으며, 이러한 충격력에 의해 탑승객은 좌우로 심하게 흔들리게 되어 상체가 도어측으로 강하게 부딪혀 상해를 입게 되는 문제점이 발생한다.Therefore, since the conventional vehicle does not have the proper rigidity against the impact force during side collision, a significant impact force is transferred to the passengers located in the cabin, the passengers are severely shaken from side to side by the impact force, the upper body is the door The problem is that the side is hit hard and injured.

특히 상기 탑승객의 머리부가 부딪히는 도어글라스는 충격력에 쉽게 파손되지 않고, 파손되더라도 유리의 예리한 조각으로부터 탑승객이 상해를 입는 것을 방지하기 위한 투명한 안전유리로 이루어져 있으므로 그 구조상 별다른 완충부재가 제공될 수 없기에 탑승자의 상해치가 높은 문제점이 있다.In particular, the door glass hit by the head of the passenger is not easily damaged by the impact force, and even if it is broken, because it is made of a transparent safety glass to prevent the passenger from injury from a sharp piece of glass, the structure of the passenger can not be provided because the cushioning member There is a problem of high injury value.

본 발명은 전술한 종래 기술의 문제점을 해소하기 위하여 창출된 것으로서, 차량 충돌시 탑승자의 머리부가 부딪히는 도어글라스 내측에 소정의 부피팽창을 이루는 완충재를 구성하여 탑승객의 머리부를 보호할 수 있는 차량의 도어글라스를 제공하는데 그 목적이 있다.The present invention was created in order to solve the above-mentioned problems of the prior art, the vehicle door that can protect the head of the passenger by configuring a cushioning material forming a predetermined volume expansion inside the door glass that the head of the occupant hit the vehicle crash The purpose is to provide a glass.

상기 목적을 달성하기 위한 본 발명의 차량의 도어글라스는 도어글라스 내측에 부착되고 소정의 부피팽창이 가능한 투명한 재질로 성형되는 복층필름과, 상기 복층필름 중앙 하측에 위치되어 차량충돌시 폭발하여 상기 복층 필름을 부피팽창시키는 약실을 포함하여 이루어지는 것을 특징으로 한다.The door glass of the vehicle of the present invention for achieving the above object is a multi-layer film attached to the inside of the door glass and formed of a transparent material capable of a predetermined volume expansion, and located in the lower center of the double-layer film to explode when the vehicle crashes the double layer It is characterized in that it comprises a chamber for volume expansion of the film.

도 1은 본 발명의 실시예가 적용될 수 있는 자동차의 사시도이고, 도 2는 본 발명의 실시예에 따른 도 1의 "A-A"선 단면도이며, 도 3은 도 2의 다른 실시예를 나타낸 단면도이다.1 is a perspective view of a vehicle to which an embodiment of the present invention can be applied, and FIG. 2 is a cross-sectional view taken along line "A-A" of FIG. 1 according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view showing another embodiment of FIG.

도시된 바와 같이, 개폐 가능하게 차체 양측에 힌지 설치된 도어(1)와, 이 도어(1)를 구성하는 도어글라스(2) 내측면에 부착되어 충돌시 탑승자의 상체를 보호하도록 부피팽창하는 복층필름(3)을 도시하고 있다.As shown, a multi-layered film which is attached to the door 1 installed on both sides of the vehicle body so as to be opened and closed, and the inner surface of the door glass 2 constituting the door 1 to protect the upper body of the occupant in the event of a collision. (3) is shown.

도 4는 본 발명의 실시예인 복층필름을 나타낸 정면도이고, 도 5는 도 4의 "B-B"선을 나타낸 단면도로서, 상기 복층필름(3)은 약실(5)을 중심으로 방사상으로 웰딩라인(4)이 형성된 것을 도시하고 있다.4 is a front view illustrating a multilayer film according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view illustrating a line “BB” of FIG. 4, wherein the multilayer film 3 is radially welded about a chamber 5. ) Is formed.

상기 복층필름(3)은 양 필름이 소정의 공간을 사이에 두고 밀폐되도록 이루어진 것으로서, 소정의 부피팽창이 가능한 재질로 투명하게 성형된다.The multilayer film 3 is formed so that both films are sealed with a predetermined space therebetween, and is transparently molded from a material capable of predetermined volume expansion.

이러한, 복층필름(3)은 도어글라스(2)에 대응하는 크기로 이루어지며, 중앙 하측에 소정의 폭발력을 보유한 약실(5)이 연통되도록 위치되고, 상기 약실(5)은 차량의 충돌을 감지하는 에어백센서(6)와 연결되며, 이 에어백센서(6)로부터 소정의 신호를 입력받아 폭발하도록 이루어진다.The multilayer film 3 has a size corresponding to the door glass 2 and is positioned such that a chamber 5 having a predetermined explosive force communicates with the lower side of the center, and the chamber 5 detects a collision of the vehicle. Is connected to the airbag sensor 6, it is made to receive a predetermined signal from the airbag sensor 6 to explode.

여기서 상기의 복층필름(3)은 상부와 하부의 부피 팽창률이 다르도록 웰딩라인(4)이 형성되며, 이 웰딩라인(4)은 약실(5)을 중심으로 방사상 방향으로 양 필름이 소정의 간격을 두고 접합되어 이루어진다.Here, the multilayer film 3 has a welding line 4 formed to have a different volume expansion ratio between the upper part and the lower part, and the welding line 4 has a predetermined interval between the films in a radial direction about the chamber 5. It is made by joining.

즉, 상기 복층필름(3)의 웰딩라인(4)은 하부에서 상부측으로 간격이 넓어지도록 이루어지며, 일정 높이 이상에서는 웰딩라인(4)이 형성되지 않는다.That is, the welding line 4 of the multilayer film 3 is formed so as to widen the gap from the lower side to the upper side, and the welding line 4 is not formed at a predetermined height or more.

상기와 같이 이루어지는 차량의 도어글라스는 다음과 같이 작용한다.The door glass of the vehicle made as described above acts as follows.

상기 본 발명의 실시예가 적용된 차량은 충돌시 발생하는 충돌력을 에어백센서(6)가 감지하여 소정의 신호를 약실(5)로 인가하게 된다.In the vehicle to which the embodiment of the present invention is applied, the airbag sensor 6 detects a collision force generated during a collision and applies a predetermined signal to the chamber 5.

이어서, 상기 약실(5)은 소정의 폭발을 일으키며, 이 약실(5)의 폭발력은 복층필름(3)내의 공간부에 작용한다.Subsequently, the chamber 5 causes a predetermined explosion, and the explosion force of the chamber 5 acts on the space part in the multilayer film 3.

따라서 상기의 복층필름(3)은 약실(5)의 폭발력에 의해 차실측으로 돌출되는 소정의 부피팽창을 이룬 상태가 된다.Therefore, the multilayer film 3 is in a state in which a predetermined volume expansion protrudes toward the vehicle compartment side by the explosive force of the chamber 5.

그러므로 충돌력에 의해 좌우로 심하게 흔들리는 탑승자는 머리부위가 도어글라스(2)측으로 부딪힐 경우에 에어백 역할을 하여 상기 탑승자의 머리부에 가해지는 충격을 저감시키게 된다.Therefore, the occupant who shakes severely from side to side due to the collision force acts as an air bag when the head hits the door glass 2 side, thereby reducing the impact on the head of the occupant.

여기서 상기 복층필름(3)은 약실(5)을 중심으로 방사상 방향으로 웰딩라인(4)을 형성하여 상부와 하부의 부피팽창률을 다르게 하고 있는데, 이는 탑승자의 머리부가 상부측에 위치하기 때문이다.Here, the multilayer film 3 forms a welding line 4 in the radial direction about the chamber 5 to change the volume expansion coefficients of the upper part and the lower part because the head of the occupant is located at the upper side.

즉, 상기 약실(5)의 폭발에 의해 복층필름(3)이 부피팽창을 이룰 경우에 하부측은 웰딩라인(4)의 간격이 좁으므로 부피팽창률이 낮아지게 되고, 상부측은 웰딩라인(4)의 간격이 넓거나 형성되어 있지 않으므로 하부측에 비하여 부피팽창률이 크게 된다.That is, when the multilayer film 3 achieves volume expansion due to the explosion of the chamber 5, the lower side has a narrow spacing of the welding line 4, so that the volume expansion rate is lowered, and the upper side of the welding line 4 Since the gap is wide or not formed, the volume expansion coefficient is larger than that of the lower side.

따라서 탑승자의 머리부가 위치하는 도어글라스(2)의 상부측은 복층필름(3)의 부피팽창률이 크게 하므로서, 충돌시 탑승자가 도어(1)측으로 부딪히게 되더라도 머리부에 가해지는 충격력을 현저히 저감시킬 수 있게 된다.Therefore, the upper side of the door glass 2 in which the occupant's head is located increases the volume expansion coefficient of the multilayer film 3, so that the impact force applied to the head can be significantly reduced even if the occupant is hit by the door 1 side during a collision. Will be.

이와 같이, 이루어지는 차량의 도어글라스는 차량 충돌시 도어글라스 내측에 제공된 복층필름에어백이 순간적으로 부피팽창을 이루어 탑승자의 머리부가 부딪히더라도 그 상해치를 현저히 저감시킬 수 있으므로 탑승객의 안전을 최대한 확보할 수 있는 이점이 있다.In this way, the door glass of the vehicle is made of a multi-layered film airbag provided inside the door glass at the time of the vehicle collision, the volume of the instantaneous expansion of the occupant's head can be significantly reduced even if the head of the occupant can be significantly reduced to ensure maximum passenger safety There is an advantage to that.

본 발명은 기재된 실시예에 한정하는 것이 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형을 할 수 있음은 이 기술 분야에서 통상의 지식을 가진 자에게는 자명하다. 따라서, 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
