Therefore, the support 16 is fixed to the belt 10 through the guide hole 15 of the guide rail 14 and the roller 18 is provided at one end thereof to move downward along the guide hole 15 so that the roller 16 The one end is fixed and the other end of the barrier plate 18 fixed to the return spring 19 is quickly moved downward to block the rear glass debris generated by the collision force to the rear passengers from the rear glass debris. It will be safe.

그리고, 상기 인너패널(13) 양내측에 각각 설치된 고정대(20)에 그 타단이 각각 고정된 리턴스프링(19)(19a) 일단을 벨트(10)와 차단판(18)에 각각 고정시켜 벨트(10)와 차단판(18)의 상, 하이동을 탄력적으로 지지하는 동시에 상기 정, 역회전하는 구동모터(7)로부터 벨트(12)의 이탈을 방지한는 것이다.In addition, one end of the return springs 19 and 19a, the other ends of which are respectively fixed to the fixing tables 20 provided on both inner sides of the inner panel 13, respectively, are fixed to the belt 10 and the blocking plate 18, respectively. 10) and the high and high dynamics of the blocking plate 18 are elastically supported, and at the same time, the belt 12 is prevented from being separated from the driving motor 7 which is rotated forward and reverse.

한편, 차단판(18)의 하강후 리어글라스(1)의 파손이 없을 경우 ECU(6)에 연결된 스위치(6a)를 동작시켜 정, 역회전하는 구동모터(7)를 역회전시켜 벨트(10)를 최초상태로 복귀시키게 되는 것이다.On the other hand, if the rear glass 1 is not damaged after the blocking plate 18 is lowered, the switch 6a connected to the ECU 6 is operated to reversely rotate the driving motor 7 which is forward and reverse and the belt 10 is rotated. ) Will be returned to its original state.

그리고, 버스의 추돌후 리어글라스(1)가 파손됨과 동시에 충격감지센서(3) 동작되어 섬유재질의 차단판(18)이 하강하여 리어글라스(1) 파편을 차단하게 된다.After the collision of the bus, the rear glass 1 is damaged and at the same time the impact sensor 3 is operated so that the blocking plate 18 of the fiber material is lowered to block the fragments of the rear glass 1.
