Abstract

PURPOSE: A seat belt shock absorber for a vehicle is provided to reduce the pressure applied to the upper body of a passenger by releasing the maximum tightening force of the seat belt in any degree when the maximum tightening force is generated in case of a collision. CONSTITUTION: A seat belt shock absorber comprises: a rotor(22) in which a seat belt is fixed with a first settlement groove(16) on both circumferences: a housing(14) equalizing a second and a third settlement groove(18,20) with the first settlement groove; and a ball(12) inserted between the first settlement groove of the rotor and the second settlement groove of the housing. In case of a collision or sudden braking, maximum tightening force is generated from the seat belt. At that time, a passenger suddenly leans to the front and the seat belt receives tensile force. Then, the first settlement groove pushes the ball to insert the ball into the second and the third settlement groove and the rotor is rotated. The ball is returned by a spring(24) and the first settlement groove is engaged with a next ball. Finally, the seat belt is lengthened as much as the motion of the first settlement groove and the pressure applied to the upper body of the passenger is reduced.

Description

자동차용 시트벨트 충격 흡수장치{Device for absorbing impact of seatbelt for automobile}Device belt absorber for automobiles {Device for absorbing impact of seatbelt for automobile}

본 발명은 자동차용 시트벨트 충격 흡수장치에 관한 것으로서, 차량의 충돌발생시에 시트벨트가 최대한계조임으로 순간 정지되는 동시에 최대한계조임에서 시트벨트가 서서히 풀리도록 함으로써, 승객의 상체에 대한 압박감을 해소시킬 수 있도록 한 자동차용 시트벨트 충격 흡수장치에 관한 것이다.The present invention relates to a seat belt shock absorber for an automobile, wherein the seat belt is momentarily stopped at the maximum gradation level at the time of a collision of the vehicle and the seat belt is gradually released at the maximum gradation level, thereby eliminating the pressure on the upper body of the passenger. The present invention relates to a seat belt shock absorber for automobiles.

통상적으로 자동차의 충돌시 또는 급브레이크시 시트벨트는 최대한계조임력을 보유하여 순간적으로 정지하게 되고, 시트벨트의 정지력에 의하여 승객이 전방으로 쏠리게 되는 것이 차단된다.In general, during a crash or sudden brake of the vehicle, the seat belt has a maximum gage force and stops momentarily, and the stopping force of the seat belt prevents the passenger from moving forward.

그러나, 승객의 전방 쏠림을 시트벨트가 차단하게 되어 상해 방지를 도모할 수 있으나, 오히려 시트벨트의 최대한계조임력에 의하여 승객의 상체는 압박을 받아 상해를 입는 경우가 있다.However, the seat belt can be prevented from injuring the front belt by the passenger, but the upper body of the passenger may be injured due to the maximum tension of the seat belt.

따라서, 본 발명은 상기와 같은 점을 감안하여 시트벨트의 최대조임력 작용시와 동시에 최대조임력을 어느 정도 풀어줌으로서, 승객의 상체 압박감을 해소시킬 수 있도록 한 자동차용 시트벨트 충격 흡수장치를 제공하는데 그 목적이 있다.Accordingly, in view of the above, the present invention provides a seat belt shock absorber for an automobile that can relieve pressure of the upper body of a passenger by releasing the maximum tightening force to a certain degree at the same time as the maximum tightening force of the seat belt. There is a purpose.

본 발명은 버클이 일측단에 장착된 시트벨트의 끝단에 설치되는 자동차용 시트벨트 충격 흡수장치에 있어서, 상기 시트벨트(26)가 고정되고 양측 원주면 제1안착홈(16)이 형성된 회전체(22)와, 상기 제1안착홈(16)과 일치되는 위치에 제2안착홈(18)과 제3안착홈(20)이 서로 관통되게 형성된 하우징(14)과, 이 하우징(14) 사이에 회전 가능하게 장착되는 상기 회전체(22)의 제1안착홈(16)과 상기 하우징(14)의 제2안착홈(18)사이에 끼워지는 볼(12)로 구성된 것을 특징으로 한다.The present invention is a vehicle seat belt shock absorber installed at the end of the seat belt buckle is mounted on one side, the seat belt 26 is fixed and the circumferential surface first seating grooves 16 formed on both sides (22) and the housing (14) formed so that the second seating groove (18) and the third seating groove (20) penetrate each other at a position coincident with the first seating groove (16), and between the housing (14). And a ball 12 fitted between the first seating groove 16 of the rotating body 22 and the second seating groove 18 of the housing 14 to be rotatably mounted to the second body.

상기 제3안착홈(20)의 안쪽면에는 만곡된 판형 스프링(24)이 고정된다.A curved plate spring 24 is fixed to the inner surface of the third seating groove 20.

여기서 상기와 같은 특징으로 갖는 본 발명을 실시예로서 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention having the features as described above will be described in more detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 자동차용 시트벨트 충격 흡수장치를 나타내는 사시도로서, 도면부호 14는 하우징이다.1 is a perspective view showing a seat belt shock absorber for a vehicle according to the present invention, wherein 14 is a housing.

상기 하우징(14)은 서로 마주보는 두개의 수직판과 이 수직판을 지지하여 차체에 고정되는 수평판으로 제작된 것으로서, 첨부한 도 2에 도시한 바와 같이 상기 각각 수직판의 안쪽면에는 다수의 제2안착홈(18)과 제3안착홈(20)이 서로 통하도록 형성된다.The housing 14 is made of two vertical plates facing each other and a horizontal plate that supports the vertical plates and is fixed to the vehicle body. As shown in FIG. The second seating groove 18 and the third seating groove 20 are formed to communicate with each other.

상기 제2안착홈(18)은 반원형이고 상기 제3안착홈(20)은 제2안착홈(18)과 공유되는 원형상이며, 제3안착홈(20)의 안쪽면에는 만곡된 판형의 스프링(24)이 부착된다.The second seating groove 18 has a semicircular shape and the third seating groove 20 has a circular shape shared with the second seating groove 18, and a curved plate spring is formed on the inner surface of the third seating groove 20. 24 is attached.

여기서 상기 하우징(14)의 수직판 사이에 회전체(22)를 회전가능하게 장착하는 바, 상기 회전체(22)의 양측 원주면에는 상기 제2안착홈(18)과 서로 일치되는 제1안착홈(16)이 형성된다.Here, the rotatable body 22 is rotatably mounted between the vertical plates of the housing 14, and both first and second seating grooves 18 coincide with the second seating grooves 18 on both circumferential surfaces of the rotatable body 22. Grooves 16 are formed.

또한, 상기 하우징(14)의 제2안착홈(18)과 회전체(22)의 제1안착홈(16)에는 볼(12)이 공유되어 롤링 가능하게 위치된다.In addition, the ball 12 is shared and rollable in the second seating groove 18 of the housing 14 and the first seating groove 16 of the rotating body 22.

한편, 상기 회전체(22)의 원주면 중간에는 시트벨트(26)의 일측단이 고정되어지고, 물론 이 시트벨트(16)의 타단에는 버클이 고정되어 있으며, 이 버클에는 리트렉터로부터 웨빙된 시트벨트의 끝단에 부착된 텅이 삽입된다.On the other hand, one end of the seat belt 26 is fixed in the middle of the circumferential surface of the rotating body 22, and of course, the other end of the seat belt 16 is fixed with a buckle, and the buckle is webbing from the retractor. The tongue attached to the end of the seat belt is inserted.

따라서, 승객이 상기 시트벨트를 착용하고 있는 상태에서 자동차의 충돌 또는 급브레이크 발생시, 승객은 시트벨트의 최대조임력(리트렉터내에서 시트벨트를 잡아주게 되어 발생)에 의하여 승객의 상체가 압박 당하게 된다.Therefore, when the vehicle crashes or sudden brake occurs while the passenger is wearing the seat belt, the passenger is pressed by the maximum tightening force of the seat belt (caused by holding the seat belt in the retractor). .

상기와 동시에 승객의 전방쏠림으로 시트벨트(26)는 당겨지는 인장력을 받게 되는 바, 이 시트벨트(26)에 의하여 상기 회전체(22)가 회전을 하게 된다.At the same time, the seat belt 26 is pulled by the passenger's forward pull, and the rotor 22 is rotated by the seat belt 26.

즉, 첨부한 도 2b에 점선으로 도시한 바와 같이 상기 회전체(22)의 제1안착홈(16)의 입구부가 상기 볼(12)을 미는 동시에 볼(12)은 하우징(14)의 제2안착홈(18)에서 제3안착홈(20)으로 밀려들어가게 되어 회전체(22)가 회전하게 되고, 제3안착홈(20)으로 밀려들어간 볼(12)은 스프링(24)에 의하여 다시 복원된다.That is, the inlet portion of the first seating groove 16 of the rotating body 22 pushes the ball 12 as shown by the dotted line in FIG. 2B, and the ball 12 is the second of the housing 14. The rotating body 22 is rotated by being pushed from the seating groove 18 to the third seating groove 20, and the ball 12 pushed into the third seating groove 20 is restored by the spring 24. do.

동시에 상기 회전체(22)의 제1안착홈(16)은 다음 또는 그 다음에 위치한 볼(12)에 치합되어지게 되고, 시트벨트(26)는 회전체(22)의 제1안착홈(16)의 위치이동만큼 늘어나게 되어, 승객의 상체 압박감이 해소된다.At the same time, the first seating groove 16 of the rotating body 22 is engaged with the ball 12 positioned next or next, and the seat belt 26 is the first seating groove 16 of the rotating body 22. ) Is increased by the position shift, and the upper body pressure of the passenger is eliminated.

이상에서 본 바와 같이, 본 발명에 따른 자동차용 시트벨트 충격 흡수장치에 의하면, 차량의 충돌시 승객의 상체를 최대조임력으로 가압하는 시트벨트의 길이를 약간 늘어나게 함으로써, 승객의 상체 압박감을 해소하여 상해를 줄일 수 있는 효과가 있다.As described above, according to the automobile seat belt shock absorber according to the present invention, by slightly increasing the length of the seat belt for pressing the upper body of the passenger to the maximum tightening force during the collision of the vehicle, the upper body pressure of the passenger to eliminate the injury There is an effect to reduce.
