It is preferable to form the pressing protrusion 34a so that the contact with the pressing table 34 inclined surface 22 is smooth.

이상과 같이 구성된 본 발명의 작동 예를 도 3 내지 도 4를 예시하여 설명하면 다음과 같다.An operation example of the present invention configured as described above will be described with reference to FIGS. 3 to 4.

도 3의 (A) 및 도 4에서와 같이 전면부(41)가 전방으로 분리되는 헤드레스트(40) 내에 장착된 본 발명은 전개스프링(42)이 탄성이 억제되어 회전고리(25)의 걸고리(26)에 걸려 고정되며, 반대편인 지지대(27)는 밀림구(21)의 외면과 맞닿아 회전고리(25)가 회동되지 못하고,As shown in FIGS. 3A and 4, the present invention is mounted in the headrest 40 in which the front part 41 is separated in the forward direction. (26) is fixed and fixed, the support 27 on the opposite side is in contact with the outer surface of the jungle 21, the rotation ring 25 is not rotated,

추(31)의 무게추(32)는 중력에 의해 지면 쪽으로 향하게 되고, 이에 따라 누름대(34)는 밀림구(21)가 눌리지 않는 경사면(22)에 위치하게 된다.  The weight 32 of the weight 31 is directed toward the ground by gravity, whereby the press 34 is located on the inclined surface 22 in which the pusher 21 is not pressed.

상기 전개스프링(42)은 탄성의 억제가 해제되면 헤드레스트(40)의 전면부(41)를 전방으로 튀어나가게 하는 스프링으로 그 구성은 당업자가 구성 가능한 다양한 방법으로 구성할 수 있다.The deployment spring 42 is a spring to protrude forward the front portion 41 of the headrest 40 when the suppression of the elasticity is released can be configured in various ways that can be configured by those skilled in the art.

도 3의 (B) 및 도 4에서와 같이 전개스프링(42)의 탄성을 억제한 상태에서 추돌사고와 같은 자동차에 충격이 가해질 경우,When the impact is applied to a vehicle such as a collision accident in a state in which the elasticity of the deployment spring 42 is suppressed as shown in FIGS. 3B and 4,

무게추(32)는 관성에 의해 그 순간은 원위치에 있으나, 헤드레스트(40)를 포함한 케이스(11)는 충격에 의해 위치가 전방으로 이동하기 때문에 결과적으로 추(31)가 반시계 방향으로 회동하면서 누름대(34)가 밀림구(21)를 누르는 경사면(22)에 위치하게 된다. The weight 32 is in the original position by moment of inertia, but since the case 11 including the headrest 40 moves forward by the impact, the weight 31 rotates counterclockwise as a result. While the presser 34 is positioned on the inclined surface 22 for pressing the pusher 21.

누름대(34)가 눌리면 회전고리(25)의 지지대(27)는 누름대(34)의 외면과 맞닿지 않게 되어 걸고리(26) 쪽보다 무거운 지지대(27)가 하측을 향하여 내려가므로, 이에 따라 회전고리(25)가 시계방향으로 회동되고,When the presser 34 is pressed, the support 27 of the rotary ring 25 does not come into contact with the outer surface of the presser 34 so that the supporter 27 that is heavier than the hook 26 is lowered toward the lower side. Rotary ring 25 is rotated clockwise,

회전고리(25)의 회동에 의해 걸고리(26)에 걸려 탄성이 억제되던 전개스프링(42)의 걸림이 해제되어 전개스프링(42)이 전면으로 펼쳐지고,By the rotation of the rotary ring 25, the catch of the deployment spring 42, which is caught by the hook 26 and the elasticity is suppressed, is released and the deployment spring 42 is spread out to the front,

이 전개스프링(42)이 펼쳐짐으로 인하여 헤드레스트(40)의 전면부(41)가 전방으로 순간 튀어나가게 탑승자의 후두부를 맞닿아 지지하게 된다. Due to the unfolding of the deployment spring 42, the front part 41 of the headrest 40 is projected forward to support the occipital head of the occupant.

추(31)가 회동되기 위한 자동차에 가해지는 충격 에너지 정도는 무게추(32)의 무게나 스프링(23)의 탄성 정도에 의해 결정된다.The degree of impact energy applied to the vehicle for the weight 31 to be rotated is determined by the weight of the weight 32 or the elasticity of the spring 23.

또한 본 발명은 다음과 같은 구성으로도 구성이 가능하며 이에 대한 설명은 도 5 및 6을 예시하여 설명하면 다음과 같다.In addition, the present invention can be configured in the following configuration, the description thereof will be described with reference to Figures 5 and 6 as follows.

회동추(51)는 헤드레스트(40) 내에 고정된 회동축봉(53)에 끼워져 회동되는 것으로, Rotating weight 51 is to be rotated by being fitted to the rotating shaft rod 53 fixed in the headrest 40,

회동추(51)의 하부에는 회동무게추(54)가 구성되고, 측부에는 전개스프링(42)을 걸어 탄성을 억제하는 회동걸고리(55)가 구성된다.Rotating weights 54 are formed at the lower portion of the rotating weights 51, and rotating hooks 55 are provided at the side to restrain the elasticity by engaging the deployment spring 42.

비틀림스프링(52)은 일반적인 차량의 움직임에 회동추(51)가 회동되지 못하 도록 고정하는 것으로,Torsion spring 52 is to fix the pivot weight 51 to prevent the rotation of the general vehicle,

비틀림스프링(52)의 한쪽은 회동추(51)에 연결되고 반대쪽은 헤드레스트(40)에 끼워진다.One side of the torsion spring 52 is connected to the pivot weight 51 and the other side is fitted to the headrest 40.

이상과 같이 구성된 본 발명의 작동 예를 도 7 내지 도 8을 예시하여 설명하면 다음과 같다.An operation example of the present invention configured as described above will be described with reference to FIGS. 7 to 8.

The deployment spring 42 whose elasticity is suppressed is rotated by the pivot 51. The hook 55 is caught and fixed, and the pivot weight 51 is fixed by the elasticity of the torsion spring 52 so that rotation is suppressed in the movement of a general vehicle.

도 7의 (B) 및 도 8에서와 같이 전개스프링(42)의 탄성을 억제한 상태에서 추돌사고와 같은 자동차에 충격이 가해질 경우,When the impact is applied to a vehicle such as a collision accident in a state in which the elasticity of the deployment spring 42 is suppressed as shown in FIGS. 7B and 8,

회동무게추(54)는 관성에 의해 그 순간은 원위치에 있으나, 헤드레스트(40)는 충격에 의해 위치가 전방으로 이동하기 때문에 비틀림스프링(52)의 탄성을 이기고 회동추(51)가 반시계 방향으로 회동하면서 걸고리(26)에 걸려 탄성이 억제되던 전개스프링(42)의 걸림이 해제되어 전개스프링(42)이 전면으로 펼쳐지고,The rotation weight 54 is in the original position by moment of inertia, but the head rest 40 is moved forward because of the impact, so the torsion spring 52 overcomes the elasticity and the rotation weight 51 is counterclockwise. When the locking spring 26 is rotated in the direction and the catch of the deployment spring 42, which is elastically suppressed, is released, the deployment spring 42 is unfolded to the front,

이 전개스프링(42)이 펼쳐짐으로 인하여 헤드레스트(40)의 전면부(41)가 전방으로 순간 튀어나가게 되어 탑승자의 후두부를 지지하게 된다. Due to the deployment spring 42 is unfolded, the front portion 41 of the headrest 40 is protruded forward to support the occipital head of the occupant.

회동추(51)가 회동되기 위한 자동차에 가해지는 충격 에너지 정도는 회동무게추(54)의 무게나 비틀림스프링(23)의 탄성 정도에 의해 결정된다.The degree of impact energy applied to the motor vehicle for the rotational weight 51 to be rotated is determined by the weight of the rotational weight 54 or the degree of elasticity of the torsion spring 23.
