Abstract

본 발명은 자동차용 립케이지형 충격완화장치에 관한 것으로서, 구체적으로 운전좌석을 사람의 갈비뼈와 같은 형태로 둘러싸도록 설치되는 립 케이지형 운전좌석 보호골격(10); 및 자동차의 속도가 지나치게 증가하거나 충돌사고 등에 의한 급정거 시에 보호골격(10)과 운전자 사이의 안전공간이 확보되도록 보호골격(10) 내측에 설치되어 보호골격(10)을 외측으로 밀어내도록 팽창되는 에어백(20); 을 구비하는 것을 특징으로 한다. 종래의 경우 에어백은 단순히 운전대와 운전자 사이의 완충장치로서만 사용되지만, 본 발명의 경우는 에어백(20)이 팽창되면 보호골격(10)이 외측으로 밀려나가기 때문에 안전공간(12)이 증가하게 된다. 따라서 소형차의 경우이더라도 대형차 이상의 안전공간을 확보할 수 있게 된다. 이러한 안전공간(12)의 확보는 충격이 운전자에게 전해지는 시간을 현저히 증가시키는 역할을 하며, 운전자에게 가해지는 충격은 시간의 제곱에 비례하여 감소한다. The present invention relates to a lip cage type shock absorber for an automobile, and more particularly, to a lip cage type seat cushion protecting structure (10) installed to surround a driving seat in the form of a rib of a person; And the protection skeleton 10 is installed inside the protection skeleton 10 so as to secure a safety space between the protection skeleton 10 and the driver at the time of sudden increase in the speed of the automobile or in case of sudden stop due to collision or the like, An airbag 20; And FIG. In the conventional case, the airbag is used merely as a shock absorber between the steering wheel and the driver, but in the case of the present invention, when the airbag 20 is inflated, the safety skeleton 10 is pushed outward, . Therefore, even in the case of a compact car, it is possible to secure a safety space over a large-sized vehicle. The securing of the safety space 12 serves to significantly increase the time that the impact is transmitted to the driver, and the impact applied to the driver decreases in proportion to the square of time.

Description

자동차용 립케이지형 충격완화장치{Rib cage shape impact relief apparatus for use in car} [0001] The present invention relates to a rib cage shape impact relief apparatus for use in a car,

본 발명은 차동차용 충격완화장치에 관한 것으로서, 특히 자동차 운전자를 보호하기 위한 자동차용 립케이지형 충격완화장치에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shock absorber for a differential car, and more particularly to a lip cage shock absorber for protecting a motor vehicle driver.

자동차에는 충돌사고 시에 엔진룸 내부의 주요부품 및 운전자를 보호하기 위하여 충격력을 완화시키기 위한 범퍼가 설치된다. 그러나 이러한 범퍼는 작은 충격력은 흡수할 수 있으나, 그 이상의 충격력에 대해서는 범퍼가 파손되면서 소형차의 경우 차량 앞부분에 있던 엔진이 차내로 밀려 들어오는 것을 막지 못하기 때문에 운전자나 탑승자의 안전에 큰 도움을 주지는 못한다. 이를 해결하고자 국내 공개실용신안공보 제1989-10571호 등에는 차체와 범퍼 사이에 완충용 공기튜브를 삽입하여 완충력을 증가시키는 내용이 개시된 바도 있다. The automobile is provided with a bumper to mitigate the impact force to protect the main parts and the driver inside the engine room in the event of a collision. However, such a bumper can absorb a small impact force. However, since the bumper is damaged in the impact force, the small-sized vehicle can not prevent the engine in the front part of the vehicle from being pushed into the vehicle, can not do it. In order to solve this problem, Korean Utility Model Publication No. 1989-10571 discloses a structure in which a buffer tube is inserted between a vehicle body and a bumper to increase the buffering force.

그러나 이러한 종래의 경우, 완충장치를 설치하였다 하더라도 운전자의 안전공간은 변함이 없기 때문에, 단지 외부로 부터의 충격을 완충시키는 것 외에는 별다른 장점이 없다. 따라서 대형사고에서는 이러한 종래의 완충장치들이 큰 효과를 보이지 못한다. 특히 소형차의 경우에는 완충장치의 설치면적이 적기 때문에 충격을 흡수하는 공간이 적어서 효과가 더욱 미미하다. However, in this conventional case, even if the shock absorber is installed, since the safety space of the driver remains unchanged, there is no merit other than merely buffering shock from the outside. Therefore, these conventional shock absorbers do not show a great effect in a large accident. Particularly, in the case of a compact car, since the installation area of the shock absorber is small, the space for absorbing shocks is small and the effect is less.

따라서 본 발명이 해결하고자 하는 과제는, 종래의 수동적인 안전시스템을 벗어나서, 사고 상황에서 실질적으로 안전공간을 확보시켜서 큰 충격을 효과적으로 흡수할 수 있도록 함으로써 소형차에 특히 유리한 자동차용 립케이지형 충격완화장치를 제공하는 데 있다. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a shock absorber for a vehicle, which is particularly advantageous for a compact vehicle, by allowing a substantial safety space to be secured in an accident situation, .

상기 과제를 달성하기 위한 본 발명에 따른 자동차용 립케이지형 충격완화장치는, 운전좌석을 사람의 갈비뼈와 같은 형태로 둘러싸도록 설치되는 립 케이지형 운전좌석 보호골격; 및 자동차의 속도가 지나치게 증가하거나 충돌사고 등에 의한 급정거 시에 상기 보호골격과 운전자 사이의 안전공간이 확보되도록 상기 보호골격 내측에 설치되어 상기 보호골격을 외측으로 밀어내도록 팽창되는 에어백; 을 구비하는 것을 특징으로 한다. According to an aspect of the present invention, there is provided a lip cage-type shock absorber for an automobile, the lip cage-type shock absorber comprising: a lip cage-type driver's seat protecting skeleton installed to surround a driver's seat; And an airbag installed inside the protection skeleton so as to push the protection skeleton outward so that a safety space between the protection skeleton and the driver is secured when the speed of the vehicle is excessively increased or when the vehicle suddenly stops due to a collision or the like. And FIG.

상기 보호골격은 차체 프레임으로 이루어지며 자동차의 전방 쪽으로 유선형을 이루는 것이 바람직하다. Preferably, the protection skeleton is formed of a body frame and is streamlined towards the front of the automobile.

상기 에어백은 자동차의 속도와 연동되어 팽창 수축이 이루어지도록 설치되 는 것이 바람직하다. Preferably, the airbag is installed so as to be expanded and contracted in conjunction with the speed of the automobile.

본 발명에 의하면, 사고상황에서 실질적인 안전공간이 증가하기 때문에 충격에 대해 운전자가 효과적으로 보호받을 수 있게 된다. According to the present invention, since the substantial safety space increases in an accident situation, the driver can be effectively protected against the impact.

이하에서, 본 발명의 바람직한 실시예를 첨부한 도면들을 참조하여 상세히 설명한다. 아래의 실시예는 본 발명의 내용을 이해하기 위해 제시된 것일 뿐이며 당 분야에서 통상의 지식을 가진 자라면 본 발명의 기술적 사상 내에서 많은 변형이 가능할 것이다. 따라서 본 발명의 권리범위가 이러한 실시예에 한정되는 것으로 해석돼서는 안 된다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are merely provided to understand the contents of the present invention, and those skilled in the art will be able to make many modifications within the technical scope of the present invention. Therefore, the scope of the present invention should not be construed as being limited to these embodiments.

도 1a 내지 도 1d는 본 발명에 따른 자동차용 립케이지형 충격완화장치를 설명하기 위한 도면으로서, 도 1a는 정면도, 도 1b는 후면도, 도 1c는 평면도, 도 1d는 측면도이다. Figs. 1A to 1D are views for explaining an impact cushioning device for an automobile lip cage type according to the present invention. Fig. 1A is a front view, Fig. 1B is a rear view, Fig. 1C is a plan view and Fig. 1D is a side view.

운전자(11)가 착석하는 운전좌석을 사람의 갈비뼈와 같은 형태로 둘러싸도록 립 케이지형 운전좌석 보호골격(10)이 설치된다. 보호골격(10)과 운전자(11) 사이에는 안전공간(12)이 형성된다. 보호골격(10)은 외부에 아예 노출되어 차체 프레임의 일부를 이루며, 속도에 방해가 되지 않도록 전방쪽은 유선형을 이룬다. A lip cage-type driving seat protection skeleton 10 is provided so as to surround the driver's seat in which the driver 11 sits in the form of a person's rib. A safety space (12) is formed between the protection skeleton (10) and the driver (11). The protection skeleton 10 is exposed to the outside to form a part of the vehicle body frame, and the front side is streamlined so as not to interfere with the speed.

보호골격(10) 내측에는 에어백(20)이 설치되는데, 에어백(20)은 마치 사람의 허파와 같이 자동차의 속도가 지나치게 증가하거나 충돌사고 등에 의한 급정거 시에 보호골격(10)을 외측으로 밀어내도록 팽창된다.  The airbag 20 is installed inside the protection skeleton 10 so that the airbag 20 is pushed out of the protection skeleton 10 when the speed of the vehicle is excessively increased or suddenly caused by a collision accident, Is expanded.

종래의 경우 에어백은 단순히 운전대와 운전자 사이의 완충장치로서만 사용되지만, 본 발명의 경우는 에어백(20)이 팽창되면 보호골격(10)이 외측으로 밀려나가기 때문에 안전공간(12)이 증가하게 된다. 따라서 소형차의 경우이더라도 대형차 이상의 안전공간을 확보할 수 있게 된다. 이러한 안전공간(12)의 확보는 충격이 운전자에게 전해지는 시간을 현저히 증가시키는 역할을 하며, 운전자에게 가해지는 충격은 시간의 제곱에 비례하여 감소한다. In the conventional case, the airbag is used merely as a shock absorber between the steering wheel and the driver, but in the case of the present invention, when the airbag 20 is inflated, the safety skeleton 10 is pushed outward, . Therefore, even in the case of a compact car, it is possible to secure a safety space over a large-sized vehicle. The securing of the safety space 12 serves to significantly increase the time that the impact is transmitted to the driver, and the impact applied to the driver decreases in proportion to the square of time.

자동차의 속도제어수단과 에어백(20)이 연동되도록 하여, 자동차가 급정거하거나 급가속할 때 갈비뼈 형태의 보호골격(10)이 외측으로 밀려나도록 함으로써 종래의 수동적인 대처와 달리 사고에 능동적으로 대처할 수 있게 된다.The speed control means of the vehicle and the airbag 20 are interlocked with each other so that the ribs of the protective ribs 10 are pushed outward when the automobile is suddenly or rapidly accelerated to actively cope with the accident .
