본 발명의 자동차용 프론트 시트 레일의 충격 완충 구조는 플로어 패널(34)면에 걸림홈(22)이 상부면에 형성된 고정 레일(10)을 장착하고, 좌우측면에 슬롯홈(20)과 스토퍼(26)가 형성된 슬라이딩 레일(12)을 상기 고정 레일(10)에 삽입 장착하되, 상기 슬라이딩 레일(12)의 슬롯홈(20)에 브라켓(14)이 끼워지는 동시에 이 브라켓(14)의 위에는 볼(18)과 스프링(16)이 장착되며, 상기 슬라이딩 레일(12) 위에는 시트(30)에 고정되는 시트 레일(24)을 장착하여서 이루어진 것을 특징으로 한다.In the shock absorbing structure of the front seat rail for automobiles of the present invention, the fixing rail 10 having the locking grooves 22 formed on the upper surface of the floor panel 34 is mounted on the floor panel 34, and the slot grooves 20 and the stoppers are disposed on the left and right sides. The slide rail 12 having the 26 formed therein is inserted into the fixed rail 10, and the bracket 14 is fitted into the slot groove 20 of the sliding rail 12, and at the same time, a ball is placed on the bracket 14. 18 and the spring 16 is mounted, characterized in that made on the sliding rail 12 by mounting the seat rail 24 fixed to the seat 30.

특히 상기 브라켓(14)에는 볼(18)의 저부가 안착되도록 관통된 안착홈(32)이 형성되고, 이 안착홈(32)에 삽입되는 볼(18)의 저면이 상기 고정 레일(10)의 걸림홈(22)에 안착되도록 한 것을 특징으로 한다.In particular, the bracket 14 is provided with a seating groove 32 through which the bottom of the ball 18 is seated, and the bottom of the ball 18 inserted into the seating groove 32 is caught by the fixing rail 10. It is characterized in that it is seated in the groove (22).

또한 상기 슬라이딩 레일(12)의 스토퍼(26)가 끼워지도록 시트 레일(24)의 양측면에는 스토퍼홈(28)이 형성된 것을 특징으로 한다.In addition, the stopper groove 28 is formed on both sides of the seat rail 24 so that the stopper 26 of the sliding rail 12 is fitted.

본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

첨부한 도 1은 본 발명에 따른 자동차용 프론트 시트 레일의 충격 완충 구조를 나타내는 분리 사시도로서, 도면 부호 10은 플로어 패널(34)에 장착된 고정 레일이다.1 is an exploded perspective view showing the shock absorbing structure of the front seat rail for automobiles according to the present invention, wherein reference numeral 10 is a fixed rail mounted to the floor panel 34.

상기 고정 레일(10)의 상부면에는 원형의 걸림홈(22)이 등간격으로 다수개 형성된다.A plurality of circular locking grooves 22 are formed in the upper surface of the fixed rail 10 at equal intervals.

여기서 상기 고정 레일(10)에 슬라이딩 레일(12)을 삽입 장착하는 바, 이 슬라이딩 레일(12)의 양측면에는 길다란 한쌍의 슬롯홈(20)이 등간격으로 다수개 형성되고, 각 슬롯홈(20)의 사이에는 스토퍼(26)가 일체로 형성된다.Here, the sliding rail 12 is inserted into and mounted on the fixed rail 10. On both sides of the sliding rail 12, a plurality of long slot grooves 20 are formed at equal intervals, and each slot groove 20 The stopper 26 is integrally formed between the two ends.

한편 상기 슬라이딩 레일(12)의 슬롯홈(20)에는 중앙에 안착홈(32)이 형성된 브라켓(14)이 끼워져 장착되고, 상기 브라켓(14)의 안착홈(32)에는 원형의 볼(18)이 올려지며, 이 볼(18) 위에는 스프링(16)이 장착된다.Meanwhile, a bracket 14 having a seating groove 32 formed therein is inserted into the slot groove 20 of the sliding rail 12, and a circular ball 18 is mounted in the seating groove 32 of the bracket 14. Is raised, and a spring 16 is mounted on the ball 18.

상기와 같이 장착된 슬라이딩 레일(12)에는 시트 레일(24)이 삽입 장착되는 바, 상기 시트 레일(24)의 양측면에는 상기 슬라이딩 레일(12)의 스토퍼(26)가 끼워지는 스토퍼홈(28)이 다수개 형성되고, 이 시트 레일(24)의 상부면은 시트(30)의 저면에 고정되어 진다.The seat rail 24 is inserted into and mounted on the sliding rail 12 mounted as described above, and the stopper groove 28 into which the stopper 26 of the sliding rail 12 is fitted to both side surfaces of the seat rail 24. A plurality of these are formed, and the upper surface of the seat rail 24 is fixed to the lower surface of the seat 30.

좀 더 상세하게는 상기 슬라이딩 레일(12)의 브라켓(14)의 안착홈(32)에는 스프링(16)의 압축력으로 볼(18)의 저부가 삽입 안착되고, 안착홈(32)의 바로 밑에는 고정 레일(10)의 걸림홈(22)이 일치되어 있는 바, 상기 볼(18)의 저면이 걸림홈(22)에 삽입되어진 상태로 유지된다.More specifically, the bottom of the ball 18 is inserted and seated in the seating groove 32 of the bracket 14 of the sliding rail 12 by the compression force of the spring 16, and fixed immediately below the seating groove 32. The locking grooves 22 of the rails 10 are coincident with each other, and the bottom surface of the ball 18 is maintained in the inserted state in the locking grooves 22.

여기서 본 발명에 따른 자동차용 프론트 시트의 충격 흡수 구조의 작용 상태를 설명하면 다음과 같다.Here will be described the operational state of the shock absorbing structure of the front seat for automobiles according to the present invention.

자동차의 후방 충돌과 동시에 충격량이 플로어 패널(34)에 장착된 고정 레일(10)에 전달되어 지면, 고정 레일(10)이 고정된 상태에서 상기 슬라이딩 레일(12)이 후방으로 이동된다.When the impact amount is transmitted to the fixed rail 10 mounted on the floor panel 34 at the same time as the rear collision of the vehicle, the sliding rail 12 is moved rearward while the fixed rail 10 is fixed.

더욱 상세하게는 상기 슬라이딩 레일(12)의 볼(18)이 상기 고정 레일(10)의 걸림홈(22)에서 이탈되어 슬라이딩 레일(12)을 위로 밀어 올림과 동시에 볼(18)의 슬라이딩으로 슬라이딩 레일(12)이 후방으로 이동하게 된다.More specifically, the ball 18 of the sliding rail 12 is disengaged from the locking groove 22 of the fixed rail 10 to push up the sliding rail 12 upward and simultaneously slide by sliding of the ball 18. The rail 12 is moved backwards.

따라서 상기 슬라이딩 레일(12)과 스토퍼(26)로 결합되어 있는 시트 레일(24)이 후방으로 이동을 하게 된다.Therefore, the seat rail 24 coupled to the sliding rail 12 and the stopper 26 moves backward.

이에 따라 상기 시트 레일(24)의 이동과 동시에 승객이 앉아 있던 시트(30)도 승객의 머리부위가 뒤로 젖혀지기 전에 후방으로 이동되어짐에 따라 승객의 머리부위가 젖혀지지 않게되어 완충을 받게 된다.Accordingly, at the same time as the seat rail 24 is moved, the seat 30 on which the passenger is sitting is also moved backwards before the head of the passenger is flipped back, thereby preventing the passenger's head from being flipped and being buffered.

상술한 바와 같이 본 발명에 따른 자동차용 프론트 시트 레일의 충격 흡수 구조에 의하면 차량의 후방 충돌시 승객의 머리가 뒤로 젖혀지며 헤드레스트에 닿기전에 시트에 앉아 있는 승객의 신체 전체가 후방 이동되도록 하여 승객의 머리 부위가 젖혀지지 않게 되므로서, 승객의 상해치를 줄일 수 있는 잇점이 있다.As described above, according to the shock-absorbing structure of the front seat rail for a vehicle according to the present invention, the passenger's head is turned back during the rear collision of the vehicle and the entire body of the passenger sitting on the seat is moved backwards before reaching the headrest. Since the head of the car is not bent, there is an advantage of reducing the passenger injury.
