본 발명은 자동차 실내의 전면 프론트판넬 하부면에 설치되어 차량충돌 사고발생시 탑승자의 무릎부위를 완충 보호하는 무릎 보호장치에 관한 것이다.The present invention relates to a knee protection device that is installed on the lower surface of the front panel of the vehicle interior to cushion and protect the knee portion of the occupant in the event of a vehicle crash.
일반적으로 차량의 충돌사고 발생시 운전자 보호장치로는 차량의 전면부에 충격력을 감지하는 센서(102)와, 상기 센서의 신호에 의해 질소가스를 폭발시키는 구동부(10), 상기 구동부(101)와 연결되어 부풀림 동작하는 에어백(100)이 핸들(103) 장착된 것은 주지의 사실이다.In general, the driver protection device when the collision accident of the vehicle occurs, the sensor 102 for detecting the impact force on the front of the vehicle, the driving unit 10 for exploding nitrogen gas by the signal of the sensor connected to the driving unit 101 It is well known that the handle 103 is mounted on the airbag 100 which is inflated and operated.
그러나 상기 에어백(100)은 차량의 충돌력에 의해 핸들(103) 부위로 전진 동작하는 운전자의 상체만을 완충시키는 장치로써, 운전자의 하체 즉, 무릎부위는 완충 보호하지 못하여 운전자의 무릎부위가 차량의 충돌력에 의해 무방비상태로 전진 동작하고, 차량전면의 엔진부는 후방으로 밀림에 따라 브레이크페달 및 클러치페달이 자동차 실내로 돌출되어 운전자의 무릎부위가 심하게 손상되는 문제점이 있었다.However, the airbag 100 is a device for buffering only the upper body of the driver moving forward to the handle 103 by the collision force of the vehicle, the lower body of the driver, that is, the knee portion of the driver can not protect the cushioning of the vehicle The driver's forward movement is unprotected by the collision force, and the brake pedal and the clutch pedal protrude into the interior of the vehicle as the engine part of the front of the vehicle is pushed to the rear, thereby seriously damaging the driver's knee.
상기 문제점을 해결하고자 종래 안출된 발명으로 탑승자의 무릎부위가 위치되는 프론트판넬(40) 하부면에 완충패드(200)가 돌출되게 고정설치되는 것이 제공된바 있으나, 상기 무릎 보호장치는 완충패드(200)가 프론트판넬(40) 외부면에 고정설치되어 차량충돌 사고시 다양한 형태로 전진동작하는 탑승자의 무릎부위에 적절하게 대응할 수 없어 본래 추구하고자 하는 목적을 충분하게 발휘하지 못하며, 완충패드(200)가 프론트판넬(40)외부로 돌출 설치되어 자동차의 실내공간을 좁아지게 하여 운전자의 운전동작에 많은 불편을 유발시키며, 승·하차시에는 더 많은 불편이 있었다.In order to solve the above problem, the shock absorbing pad 200 is provided to be fixed to the front surface of the front panel 40 where the knee part of the occupant is positioned to protrude, but the knee protection device is provided as a shock absorbing pad 200. ) Is fixedly installed on the outer surface of the front panel 40 and can not adequately respond to the knee portion of the occupant kneeling forward in various forms in the event of a vehicle crash does not fully serve the purpose of the original pursuit, cushion pad 200 is Installed outside the front panel 40 to narrow the interior space of the car causing a lot of inconvenience for the driver's driving operation, there was more inconvenience when getting on and off.
따라서 본 발명은 상기한 바와 같은 종래 제반 문제점을 해결하기 위한 것으로써, 본 발명의 목적은 완충패드를 유동가능하게 설치하여 다양한 형태로 전진동작하는 무릎부위에 적절하게 대응할 수 있는 운전자 무릎 보호 장치를 제공함에 있다.Therefore, the present invention is to solve the conventional problems as described above, the object of the present invention is to install a shock absorber pad to the driver knee protection device that can appropriately respond to the knee region to move forward in various forms In providing.
본 발명의 또다른 목적은, 완충패드가 차량충돌시에만 프론트판넬 외부로 돌출되고 평상시에는 프론트판넬내부에 삽입상태를 이루게 함으로써, 자동차의 실내공간을 효율적으로 활용할 수 있도록 하는 운전자 무릎보호장치를 제공함에 있다.Still another object of the present invention is to provide a driver's knee protection device that allows the shock absorbing pad to protrude to the outside of the front panel only during a vehicle collision and to be inserted into the front panel during normal use, thereby effectively utilizing the interior space of the vehicle. Is in.
상기 목적을 달성하기 위한 본 발명의 특징은 프론트판넬의 하부면에 패드삽입홈을 형성하고 상기 홈내로 완충패드를 삽입설치하며, 상기 완충패드의 후방은 차량충돌 사고시 패드를 홈 외부로 돌출 동작시키는 돌출장치와 힌지가 결합된 것에 있다.A feature of the present invention for achieving the above object is to form a pad insertion groove in the lower surface of the front panel and to install a buffer pad into the groove, the rear of the buffer pad to protrude the pad out of the groove during a vehicle crash accident The protrusions and hinges are combined.
그리고 이미 알려진 일본공개실용 평 2-7051호는 무릎보호대가 고정식이여서 보호 효과가 미흡하였다.In addition, the already known Japanese public use room No. 2-7051 has a lack of protection because the knee protector is fixed.
본 발명 상기 제반 결점을 재거키 위한 것으로서 그 요지를 첨주된 도면에 의거하여 보다 상세하게 설명하면 다음과 같다.The present invention will be described in more detail based on the attached drawings as a summary of the above-mentioned shortcomings.
도면 제2도 및 제3도에 도시한 바와 같이, 자동차의 운전석 전면에 설치되는 프론트판넬(40), 하부면에 완충패드가 삽입되는 홈(41)과, 상기 프론트판넬(40)의 후방내측에 에어백(100)을 동작시키는 구동부(101)와 연결되는 실린더(11)와 상기 실린더 내부에 삽입되어 구동부(101)로 부터 전달된 개스압력에 의해 돌출 동작하는 로드(12)로 이루어지는 돌출장치(10)가 설치되며, 상기 돌출장치(10)는 에어백(100)을 동작시키는 구동부(101)가 아닌 별도의 독립된 구동원을 사용할 수도 있는 것이다.2 and 3, the front panel 40 installed on the front of the driver's seat of the vehicle, the groove 41 in which the buffer pad is inserted into the lower surface, and the rear inner side of the front panel 40. Protruding device consisting of a cylinder (11) connected to the drive unit 101 for operating the airbag 100 and a rod 12 inserted into the cylinder and protruding by the gas pressure transmitted from the drive unit 101 ( 10 is installed, the protruding device 10 may use a separate independent drive source, not the drive unit 101 for operating the airbag 100.
이와 같이 구성되는 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.
차량의 평상시 주행중에는 완충패드(20)가 프론트판넬(40)의 홈(41)내에 삽입된 상태를 유지하게 되어 운전자의 운전동작이나 승,하차시에 아무런 지장을 유발시키지 않게 되다가 차량의 충돌사고가 발생될 경우에는, 차량전면에 설치된 충격감지센서(102)가 충돌충격력을 감지하여 구동부(101)에 감지신호를 전가시킴에 따라, 구동부(101)내의 개스가 폭팔하여 강한 압력이 발생되어 핸들(103)에 설치된 에어백(100)을 부풀러 운전자의 상체를 완충 보호하고, 일부의 개스는 돌출수단(10)의 실린더(11) 내부로 유입되어 로드(12)를 돌출전진 동작시키게 되고, 로드선단에 결합된 완충패드(20)는 프론트판넬(40)의 홈(41) 외부로 돌출되어 전진동작하는 운전자의 무릎부위 충격력을 폴리우레탄폼(22)이 흡수 완충하여 보호하게 된다.During normal driving of the vehicle, the shock absorbing pad 20 is inserted into the groove 41 of the front panel 40 so that the driver's driving operation or getting on or off the vehicle is not caused, and the vehicle crashes. Is generated, the shock sensor 102 installed on the front of the vehicle detects the impact impact force and transmits the detection signal to the driving unit 101, the gas in the driving unit 101 is exploded and a strong pressure is generated to handle The airbag 100 installed in the 103 is inflated to protect the upper body of the driver, and some gas flows into the cylinder 11 of the protruding means 10 to protrude and advance the rod 12. The shock absorbing pad 20 coupled to the front end protrudes outside the groove 41 of the front panel 40 so that the polyurethane foam 22 absorbs and protects the impact force of the driver's knee, which moves forward.
이때 상기 완충패드(20)는 돌출동작하는 로드(12) 선단에 힌지결합되어 운전자의 무릎부위가 어떠한 형태로 접촉되더라고 힌지부(13)를 중심으로 선회동작하여 적절하게 대응되는 것이다.At this time, the shock absorbing pad 20 is hinged to the tip of the rod 12 protruding to be rotated about the hinge portion 13, even if the driver's knee contact in some form to correspond appropriately.
이상에서와 같이 본 발명에 따른 운전자 무릎 보호장치에 의하면, 평상시 주행중에는 완충패드가 프론트판넬의 홈내부에 삽입된 상태를 유지하게 되어 운전자의 운전동작 및 승, 하차동작에 아무런 지장을 유발시키지 않게 되어 차량의 실내공간을 보다 효율적으로 활용할 수 있는 효과와, 아울러 차량 충돌사고시 운전자의 무릎형태에 적절하게 대응할 수 있어 무릎 충격력을 보다 효과적으로 흡수 완충시켜 운전자 부상을 최소화 할 수 있는 아주 유용한 발명인 것이다.As described above, according to the driver knee protection device according to the present invention, the cushion pad is maintained in the state inserted into the groove of the front panel during normal driving so as not to cause any trouble to the driver's driving operation and getting on and off. Therefore, it is a very useful invention that can effectively utilize the interior space of the vehicle, and can also appropriately respond to the driver's knee shape in the event of a vehicle crash, so as to effectively absorb and cushion the knee impact force to minimize the driver injury.
