Such safety devices include air bags and seat belts. In the crash pad disposed to extend in the transverse direction of the vehicle body to mount the instrument, the shock absorber is provided to protect the knee of the passenger in the front seat.

즉, 상기 충격흡수장치는 도 1에 도시된 바와 같이, 크래쉬패드(도시안됨)내에서 차체의 횡방향을 따라 길게 형성되어 배치되는 카울크로스멤버(10)와, 이 카울크로스멤버(10)의 전면부위에 접합되어 고정되는 마운팅브라켓트(12) 및, 이 마운팅브라켓트(12)의 전면으로 접합되어 고정되는 무릎보호용 불스터패널(14;bolster panel)로 구성된다.That is, the shock absorbing device is, as shown in Figure 1, in the crash pad (not shown) formed long along the transverse direction of the vehicle body and the cowl cross member 10, The mounting bracket 12 is bonded to the front part and fixed, and the knee protection bullster panel 14 is joined to the front of the mounting bracket 12 and fixed.

여기서, 상기 마운팅브라켓트(12)는 카울크로스멤버(10)의 양측 선단부위에 배면이 접합되어 고정되는 것으로, 상기 카울크로스멤버(10)측에 접합되는 제1장착부재(12a)와, 이 제1장착부재(12a)의 전면에서 상하로 이격되게 형성된 제2장착부재(12b) 및, 이 제2장착부재(12b)의 전면으로 접합되는 제3장착부재(12c)로 이루어져, 상기 무릎보호용 불스터패널(14)의 배면이 제3장착부재(12c)상에 접합되어 고정된다.Here, the mounting bracket 12 is a rear surface is bonded to both front ends of the cowl cross member 10 is fixed, the first mounting member (12a) is joined to the cowl cross member 10 side, and the first A second mounting member 12b formed to be spaced up and down from the front surface of the mounting member 12a, and a third mounting member 12c joined to the front surface of the second mounting member 12b. The back surface of the panel 14 is joined and fixed on the third mounting member 12c.

따라서, 차량의 정면 충돌 및 추돌사고시 관성에 의해 전방좌석에 탑승한 승객이 차량의 전방을 향해 이동하면서 승객의 무릎부위가 크래쉬패드의 하부의 빈공간으로 진입할 때, 승객의 무릎부위는 상기 무릎보호용 불스터패널(14)과 부딪치면서 이동을 저지받게 된다.Therefore, when a passenger in the front seat is moved toward the front of the vehicle due to inertia during a frontal collision and collision, the knee of the passenger enters the empty space under the crash pad. The collision with the protective bullster panel 14 is prevented from moving.

그런데, 상기와 같이 구성된 종래의 충격흡수장치에서는, 정면 충돌 및 추돌사고시 단순히 전방좌석에 탑승한 승객의 무릎부위가 크래쉬패드내로 진입하게 되어 크래쉬패드의 하부에 위치한 부품들과의 충돌로 인한 큰 상해, 예컨대 무릎이하부위가 절단되는 등의 상해를 입게 되는 것만을 방지할 수 있을 뿐, 상기 무릎보호용 불스터패널(14)과 탑승한 승객의 무릎부위가 부딪치게 되면서 승객의 무릎뼈가 손상되는 것은 방지할 수 없는 단점이 있다.By the way, in the conventional shock absorbing device configured as described above, the knee portion of the passenger in the front seat simply enters the crash pad during a frontal collision and collision accident, causing a great injury due to collisions with parts located below the crash pad. For example, it is only possible to prevent injuries such as cutting below the knee, and preventing the knee protection of the passenger from being damaged while the knee protection bullster panel 14 collides with the knee of the passenger. There is a disadvantage that can not.

이는, 상기 카울크로스멤버(10)상에 마운팅브라켓트(12)를 매개로 고정설치된 무릎보호용 불스터패널(14)이 금속재의 강체로 이루어져 있기 때문에 불가피한 것이다.This is inevitable because the knee protection bullster panel 14 fixed on the cowl cross member 10 via the mounting bracket 12 is made of a rigid metal material.
