본 발명은, 차량운전자의 보호장치에 관한 것으로, 특히, 니이백(knee bag) 장치라고 하는, 운전자의 다리부분의 보호장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection device for a vehicle driver, and more particularly, to a protection device for a driver's leg, called a knee bag device.

차량의 좌석에 앉은 운전자의 다리의 앞쪽에서 전개되는 에어백(니이백)을 설치하는, 차량 운전자의 보호장치는, 일본국 실공소 제47-24110호 공보와 일본국 특개평 제3-28050호 공보에 기재되어 있다.The protection device of a vehicle driver, which installs an airbag (needle bag) that is deployed in front of a driver's leg sitting in the seat of the vehicle, is disclosed in Japanese Unexamined Patent Publication No. 47-24110 and Japanese Unexamined Patent Application Publication No. 3-28050. It is described in.

이러한 니이백을 전개시키므로써, 운전자의 하강운동(신체가 좌석의 앞쪽 밑으로 내려가는 현상)을 방지하여 운전자의 하반신을 보호할 수 있다.By deploying the knee bag, the lower body of the driver can be protected by preventing the driver's lowering movement (body falling down the front of the seat).

상기한 각 공보에서 공지된 차량 운전자의 보호장치에서는, 에어백장치를 좌석의 중앙 전방에 배치하고 있다.In the vehicle driver protection device known from the above publications, the airbag device is disposed in front of the center of the seat.

이 때문에, 에어백장치가 승객의 발 밑 가까이에 위치하게 되어, 차량 내에서의 거주성이 악화한다고 하는 문제가 있었다.For this reason, the airbag apparatus is located near the foot of a passenger, and there exists a problem that the inhabitability in a vehicle deteriorates.

본 발명에 의한 차량 운전자의 보호장치는, 좌석의 전방이며, 또한 좌석의 좌면높이 근처를 포함하는 높이의 영역에서 전개되는 에어백을 사용하는 에어백장치로 구성된 차량 운전자의 보호장치에 있어서, 상기한 에어백장치는, 스티어링컬럼의 좌측으로부터 우측까지 뻗어있는 가로로 긴 편평형상인 것을 특징으로 하는 것이다.A protective device for a vehicle driver according to the present invention is a protective device for a vehicle driver comprising an airbag device that uses an airbag that is in front of the seat and is deployed in an area of a height including near the seat height of the seat. The device is characterized in that it is a horizontally long flat shape extending from the left side to the right side of the steering column.

이러한 본 발명에 있어서는, 에어백장치가 박형(薄形)이므로, 운전자의 발 밑으로부터 에어백장치까지의 거리가 길어지며, 따라서, 운전자의 발 밑 주위의 공간을 넓게 취할 수 있게 된다.In the present invention, since the airbag device is thin, the distance from the driver's foot to the airbag device is long, and thus the space around the driver's foot can be made wider.

[실시예]EXAMPLE

다음에, 도면을 참조하면서 실시예에 대해서 설명한다.Next, an Example is described, referring drawings.

제1도는, 본 발명의 실시예에 의한 차량 운전자의 보호장치를 설치한 자동차 내부의 사시도, 제2도는, 제1도에서 Ⅱ-Ⅱ선을 따르는 단면도, 제3도 및 제4도는, 에어백의 전개형상을 설명하는 설명도이다.1 is a perspective view of the inside of a vehicle provided with a protection device for a vehicle driver according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIGs. It is explanatory drawing explaining an expanded shape.

제1도에서, (10)은 인스트루먼트패널, (12)는 스티어링휠, (16)은 좌석이다.In FIG. 1, reference numeral 10 denotes an instrument panel, 12 a steering wheel, and 16 a seat.

스티어링휠(12)은 스티어링컬럼(18)(제2도)의 선단에 부착되어 있으며, 스티어링컬럼(18)은 컬럼커버(20)로 덮혀있다.The steering wheel 12 is attached to the tip of the steering column 18 (FIG. 2), and the steering column 18 is covered with the column cover 20.

컬럼커버(20)의 우측으로부터 좌측까지 뻗어있는, 가로로 긴 편평형상의 에어백장치(22)가 인스트루먼트패널(10)에 부착되어 있다.A horizontally long flat airbag device 22 extending from the right side to the left side of the column cover 20 is attached to the instrument panel 10.

제2도에서 표시하는 바와 같이, 에어백장치(22)는, 리테이너(부착판)(24), 리테이너(24)에 부착된 인플레이터(가스발생기)(25), 리테이너(24)에 부착되어 있으며, 인플레이터(25)의 방출가스에 의해 전개되는 에어백(26), 에어백(26)을 덮고있는 모듈커버(28) 등으로 구성되어 있다.As shown in FIG. 2, the airbag apparatus 22 is attached to the retainer (attachment plate) 24, the inflator (gas generator) 25 attached to the retainer 24, and the retainer 24, And the module cover 28 covering the airbag 26, the airbag 26 deployed by the discharge gas of the inflator 25, and the like.

본 실시예에 의한 에어백장치(22)는, 좌우 폭방향에서의 중앙이 약간 앞쪽으로 만곡하여 돌출하는 형상인 것이며, 만곡된 부분의 뒷쪽에 상기한 컬럼커버(20)가 자리잡고 있다.The airbag device 22 according to the present embodiment has a shape in which the center in the left and right width directions is slightly curved forward to protrude, and the above-described column cover 20 is located behind the curved portion.

또, 인스트루먼트패널(10)에는 삽입구(30)가 형성되어 있으며, 이 삽입구(30)에 상기한 인플레이터(26)가 삽입되므로써, 에어백장치(22)의 전방으로의 돌출폭을 한층 작게 할 수 있다.In addition, an insertion opening 30 is formed in the instrument panel 10, and the inflator 26 is inserted into the insertion opening 30, so that the projection width toward the front of the airbag device 22 can be further reduced. .

이와 같이 구성된 차량 운전자의 보호장치에서는, 차량의 충돌 등에 의한 전방으로의 큰 가속도가 발생되면, 가속도센서(도면에서의 표시는 생략)로 부터의 신호에 의해 인플레이터(25)가 작동되면서 에어백(26)이 전개된다.In the vehicle driver protection device configured as described above, when a large acceleration forward occurs due to a collision of the vehicle or the like, the inflator 25 is operated by a signal from an acceleration sensor (not shown in the drawing) and the airbag 26 is operated. ) Is developed.

이에 의해서 제3도와 제4도에서 표시하는 바와 같이, 전개되는 에어백(26)에 의해 모듈커버(28)가 눌리면서 개열되어, 에어백(26)이, 좌석(16)의 전방이며, 좌석의 좌면높이 근처를 포함하는 높이의 영역으로 전개된다.As a result, as shown in FIG. 3 and FIG. 4, the module cover 28 is opened while the module cover 28 is pressed by the deployed airbag 26 so that the airbag 26 is in front of the seat 16, and the seat height of the seat is increased. It develops into an area of height, including nearby.

그러므로, 차량의 충돌에 의해, 좌석(16)에 앉아있던 운전자의 발이 전방으로 이동한다 하더라고, 운전자의 발은 에어백(26)에 의해 보호된다. 그리고, 제1도와 제2도에서 표시하는 바와 같이, 에어백장치(22)가 편평형상을 하고 있으므로, 좌석(16)에 앉은 운전자의 발 밑부분의 공간을 넓게 취할 수 있다.Therefore, even if the driver's foot sitting on the seat 16 moves forward by the collision of the vehicle, the driver's foot is protected by the airbag 26. As shown in FIG. 1 and FIG. 2, since the airbag device 22 has a flat shape, the space under the driver's foot sitting on the seat 16 can be made wider.

따라서, 차량 실내에서의 거주성이 극히 뛰어난 것으로 된다.Therefore, the occupancy in the vehicle interior is extremely excellent.

상기한 실시예에서는 인플레이터(25)가 1개만 설치되어 있지만, 2개 이상 설치하여도 좋다.In the above embodiment, only one inflator 25 is provided, but two or more inflators 25 may be provided.

이상과 같이, 본 발명에 의한 차량 운전자의 보호장치는, 에어백장치의 두께가 작기 때문에, 좌석에 앉은 운전자의 발 밑 주위의 공간을 넓게 취할 수 있으며, 따라서 차량 실내에서의 거주성을 높일 수 있다.As described above, the protective device for a vehicle driver according to the present invention has a small thickness of the airbag device, so that the space around the foot of the driver sitting in the seat can be widened, thereby improving the occupability in the vehicle interior. .

또, 에어백이 좌석 전방에서의 좌우방향으로 넓게 분포한 형태로 설치되므로, 에어백을 좌석의 전방에서의 좌우방향으로 균일하게, 또, 신속하게 전개시키는 것이 용이하다.In addition, since the airbags are provided in a form distributed widely in the left and right directions at the front of the seat, it is easy to deploy the air bags uniformly and quickly in the left and right directions at the front of the seat.
