본 발명은, 승용차의 전복사고 혹은 후방충돌사고 발생시 그 충격 순간 뒷유리창을 통하여 뒷좌석 승객이 이탈되면서 일어나는 2차적 사고를 방지하기 위하여 뒷유리창의 테두리 트림커버를 따라 소정의 검출장치를 설치하고, 이로부터 검출된 신호에 따라 인플레이터(Inflator)가 작동하여 뒷유리창 연부의 트림커버에 설치된 에어튜브가 팽창하게 한 승용차 사고시 뒷좌석 보호장치에 관한 것이다.The present invention is to install a predetermined detection device along the rim trim cover of the rear windshield in order to prevent secondary accidents that occur when the rear seat passenger is separated through the rear windshield at the moment of impact when the vehicle is overturned or rear collision accident, According to the detected signal from the Inflator (Inflator) to operate the air tube installed in the rear cover of the rear cover of the rear cover relates to a rear seat protection device in the event of a car accident.

일반적으로 승용차의 전복사고나 후방충돌 사고시에 흔치않게 뒷좌석 승객이 사고 순간의 1차적 충격외에 충격과 동시에 차체가 뒤집어지는 경우 뒷유리창으로 이탈되어 2차적 사고를 유발하고 있으며 이로인한 인명피해가 더 심하게 발생되고 있다.In general, in case of overturning or rear-crashing of a passenger car, when the rear seat passenger is inclined at the same time as the impact of the accident besides the primary shock, the vehicle is displaced to the rear window, causing secondary accidents. It is occurring.

그 동안 전방충격에 대해서는 운전자나 조수석 탑승자의 보호를 위하여 여러 가지 보호장치가 제안되어 적용되어 왔고, 상기와 같은 후방충격에 대해서도 여러 가지의 안전장치가 제안되어 왔으나 실제로 적용되는 못하고 있다. 그 원인은 후방충돌 사고나 전복사고라 하더라도 대부분의 차량사고시 뒷좌석 승객들은 거의 큰 사고를 당하지 않았기 때문이다.In the meantime, various protection devices have been proposed and applied for the protection of the driver or the front passenger for the front shock, and various safety devices have been proposed for the rear shock as described above, but are not actually applied. The reason for this is that even in the case of a rear collision or rollover accident, most of the rear seat passengers were hardly hit during the crash.

본 고안에서는 이와같은 뒷좌석 승객이 거의 다치지 않는 경우가 아니라 차량의 전복이나 후방충돌에 의하여 뒷좌석 승객이 뒷유리창을 통하여 이탈되는 정도의 상당한 사고에 대비한 뒷좌석 승객의 보호장치를 제안하고자 하는 것이다.In the present invention, the rear seat passenger is hardly injured. Instead, a rear seat passenger protection device is prepared for a significant accident such that the rear seat passenger is separated through the rear windshield due to the vehicle's overturning or rear collision.

이와같은 전복사고나 후방충돌시에도 1차적 충격만으로 뒷좌석 탑승자가 보호될 수 있다면 그동안 많은 인명사고에서 볼 수 있는 뒷유리창을 이탈한 탑승자가 다른 차량이나 해당 차량에 깔려 사망하는 사고를 미연에 방지할 수 있기 때문이다.If a rear seat occupant can be protected by a primary shock even during such a rollover or rear-end collision, it is possible to prevent an occupant who has fallen off the rear windshield, which is seen in many human accidents, by being hit by another vehicle or the vehicle. Because it can.

본 발명은 상기와 같은 차량의 전복사고나 후방충돌에 의한 사고시에 2차적 피해를 줄이기 위하여 뒷유리창을 통한 탑승자의 이탈을 방지할 수 있는 보호장치를 제공하는 데에 그 목적이 있다.An object of the present invention is to provide a protective device that can prevent the departure of the occupant through the rear window in order to reduce secondary damage in the event of an overturn or rear collision of the vehicle as described above.

이와같은 목적을 달성하기 위하여 본 발명은 차체의 뒷부분은 유리창을 둘러싸고 바디패널과; 이 바디패널에 결합되어 내측으로는 공간을 형성하고 외측일부에는 길이 방향으로 절취선을 형성한 트림커버와; 상기 트림커버의 내부 공간을 따라 길게 위치하면서 일정위치에서 고압의 공기로 팽창되면서 상기 트림커버의 전개와 동시에 팽창하여 뒷유리창의 연부를 따라 일정크기로 보호막을 형성하는 에어튜브와; 상기 에어튜브의 작동을 제어하기 위하여 전원부, 충돌 및 전복상태를 검출하는 검출수단, 이 검출수단의 결과에 따라 상기 에어튜브를 팽창시켜 보호막을 형성하기 위한 인플레이터; 로 이루어진 충격검출장치를 포함하여 이루어지는 차량사고시 뒷좌석 보호장치에 의하여 가능하다.In order to achieve the above object, the present invention is the rear portion of the vehicle body surrounding the glass window and the body panel; A trim cover coupled to the body panel to form a space inward and a cutout line in a length direction on the outer part; An air tube which is positioned along the inner space of the trim cover and expands with high pressure air at a predetermined position and expands at the same time as the trim cover is developed to form a protective film with a predetermined size along the edge of the rear window; A power supply unit, detection means for detecting a collision and rollover condition for controlling the operation of the air tube, an inflator for inflating the air tube to form a protective film according to the result of the detection means; It is possible by the rear seat protection device in the event of a vehicle accident comprising an impact detection device made of.

상기와 같은 본 발명의 뒷좌석 보호장치에 의하여 승용차의 전복사고나 후방충돌등의 사고 발생시에 뒷유리창의 연부를 둘러싸는 바디후레임의 내측에 설치되어 충격에 의하여 팽창하는 에어튜브가 유리창의 중심 일부를 제외하고는 대부분을 뒤덮고 있기 때문에 아무리 강한 충격이 있더라도 뒷좌석 탑승자는 뒷유리창이 깨어지면서 이탈되는 일은 일어나지 않게 되므로 그동안 뒷유리창을 통하여 이탈된 탑승자 대부분이 사망하게 되는 일은 방지가 될 수 있는 것이다.By the rear seat protector of the present invention as described above, the air tube is installed inside the body frame surrounding the edge of the rear window at the time of an accident such as a rollover or rear collision of the passenger car and expands due to the impact of the center of the windshield. Because it covers most of them, no matter how strong the impact is, the rear seat occupant does not break off the rear window, so that most of the passengers who escaped through the rear window can be prevented from being killed.

이하 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면중 제1도는 본 발명의 에어튜브가 팽창된 상태를 나타내는 차량의 내부 개략도이고, 제2도는 제1도의 A-A선 단면도로서 이에 따르면 본 발명은 크게 뒷유리창을 둘러싸는 바디패널(1)과, 트림커버(2)와, 에어튜브(3)와, 충격검출장치(4)로 이루어지는 것으로 보다 구체적으로 각부분을 설명한다.1 is an internal schematic view of a vehicle showing an inflated state of the air tube of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 according to the present invention. The trim cover 2, the air tube 3, and the impact detection device 4 will be described in more detail.

뒷유리창을 둘러싸는 바디패널(1)에 결합되는 트림커버(2)는 바디패널(1)과의 사이에 내측으로 공간(21)을 형성하고 외측일부에는 길이 방향으로 절취선(22)을 형성한다. 이 절취선(22)은 일정 압력 이상의 팽창력이 발생되면 쉽게 터져 나오도록 형성되며 뒷유리창 전체를 둘러싸는 트림커버 전체에 형성되어 있다.The trim cover 2 coupled to the body panel 1 surrounding the rear window forms a space 21 inwardly between the body panel 1 and a perforation line 22 in the length direction of the outer part. . The cut line 22 is formed to easily burst when an expansion force of a predetermined pressure is generated and is formed on the entire trim cover surrounding the entire rear window.

에어튜브(3)는 상기 트림커버(2)의 내부공간(21)을 따라 길게 위치하면서 일정위치에서 고압의 공기로 팽창되면서 상기 트림커버(2)의 전개와 동시에 팽창하여 뒷유리창의 연부를 따라 일정 크기로 보호막을 형성하는 구조로 이루어진다.The air tube 3 is positioned along the inner space 21 of the trim cover 2 and expands with high pressure air at a predetermined position and expands at the same time as the trim cover 2 is expanded to follow the edge of the rear window. It is made of a structure to form a protective film in a predetermined size.

충격검출장치(4)는 상기 에어튜브(3)의 작동을 제어하기 위하여 전원부(41)와, 충돌 및 전복상태를 검출하는 검출수단(42)과, 이 검출수단(42)의 검출 결과에 따라 상기 에어튜브(3)에 고압 공기를 충진시켜 팽창되는 보호막을 형성하기 위한 인플레이터(43)로 이루어진다.The impact detection device 4 has a power supply unit 41 for controlling the operation of the air tube 3, detection means 42 for detecting a collision and overturning state, and a detection result of the detection means 42. It consists of an inflator 43 for filling the air tube 3 to form a protective film which is expanded by filling high pressure air.

인플레이터(43)은 에어백 시스템의 가스 발생장치로서 가스 발생제인 통상의 아질산 나트륨을 순간적으로 연소시켜 질소가스를 발생시킴에 따라 에어튜브가 팽창되는 원리를 가진다.The inflator 43 is a gas generator of an airbag system, and has a principle of expanding an air tube as it generates nitrogen gas by instantaneous combustion of conventional sodium nitrite which is a gas generator.

이와같이 이루어진 본 발명의 작동과정을 첨부도면 제3도의 작동 과정을 나타내는 블록도에 의하여 살펴보면, 충격검출장치의 검출수단(42)(통상 센서를 사용)은 항시 전원부(41)의 전원이 공급되는 상태에서 오작동이라든가 후방 및 전복상태를 체킹하게 되며 갑작스런 사고가 발생되어 후방충돌 및 전방상태가 되면 이를 자동적으로 검출하여 인플레이터(43)을 작동시키게되며, 인플레이터(43)가 작동되면 위에서 설명된 가스발생제가 연소되면서 질소가스가 에어튜브(3)내로 순간 공급되어 에어튜브(3)를 팽창시키게 된다.Referring to the block diagram showing the operation of the present invention made as shown in FIG. 3, the detection means 42 (normally using a sensor) of the impact detection device is always supplied with power from the power supply unit 41. In the case of malfunction or check the rear and overturned state, and sudden accidents occur in the rear collision and forward state automatically detects this to operate the inflator 43, when the inflator 43 is operated the gas generator described above As it is combusted, nitrogen gas is instantaneously supplied into the air tube 3 to inflate the air tube 3.

에어튜브(3)의 팽창력은 트림커버(2)의 절취선(22)을 순간 전개시키면서 뒷유리창의 테두리 일정폭까지 확장되어 뒷유리창의 중앙부분 약간을 제외하고는 대부분 뒤덮게 되어 차량의 전복이나 후방충돌이 가해지더라도 뒷좌석 탑승자가 뒷유리창을 통한 탑승자의 이탈로 인하여 발생되는 2차적 사고에 의한 사고의 중상화를 방지하게 되는 것이다.The inflation force of the air tube 3 extends to a certain width of the edge of the rear windshield by unfolding the perforation line 22 of the trim cover 2 to cover most of the rear window except for the center portion of the rear windshield. Even in the event of a collision, the rear seat occupant prevents the slander of the accident caused by the secondary accident caused by the departure of the occupant through the rear windshield.
