Description

자동차 시트의 회전가능한 헤드레스트{Adjustable headrest for vehicle seat}Rotatable headrest for car seats {Adjustable headrest for vehicle seat}

본 발명은 자동차 시트의 회전가능한 헤드레스트 구조에 관한 것으로, 더욱 상세하게는 시트백의 상부에 설치되는 헤드레스트를 탑승자가 간단한 조작으로 상하이동 및 전후방향으로의 회전이 가능하도록 발명된 것이다.The present invention relates to a rotatable headrest structure of an automobile seat, and more particularly, to a headrest provided on an upper portion of the seatback so as to allow the passenger to rotate in the forward and backward directions with a simple operation.

일반적으로, 자동차에는 충돌이 발생될 경우 탑승자의 머리 뒷쪽 이동과 충격을 억제하여 경부상해를 완화시키고, 시트에서의 승차감을 향상시키기 위하여 시트백 상단에는 헤드레스트(HEAD REST)가 설치되어 있다.In general, when a collision occurs, a headrest is installed at the top of a seat back to reduce a neck injury and to improve ride comfort in a seat by suppressing movement and impact behind the occupant's head.

이러한 헤드레스트는 높이 조절이 가능한 구조로 되는 것과 고정적인 것이 동시에 사용되고 있으나, 헤드레스트의 상, 하 높이 조절이 가능한 구조는 전부 해당된다.Such a headrest is used to be a structure that can be adjusted in height and a fixed one at the same time, the structure that can adjust the height of the headrest, the top and bottom are all applicable.

그리고, 헤드레스트 구조에는 도 1에서 도시한 것과 같이, 상기 헤드레스트 내부로 지지대(1)가 고정설치되어 있으며, 상기 지지대(1)의 단부는 헤드레스트(10)의 하부로 돌출되게 형성된다.In addition, as shown in FIG. 1, the headrest structure has a support 1 fixed to the inside of the headrest, and an end of the support 1 is formed to protrude downward from the headrest 10.

또한, 상기 지지대(1)를 고정할 수 있도록, 시트백(11)과 헤드레스트(10)의 접지면에는 가이드부(2)가 구비되고, 상기 가이드부(2)의 접지면에는 지지대(1)의 상, 하 이동폭을 결정하는 푸쉬노브(3)가 형성되어 있다.In addition, the guide portion 2 is provided on the ground plane of the seatback 11 and the headrest 10 so that the support 1 can be fixed, and the support base 1 is provided on the ground plane of the guide portion 2. Push knobs 3 for determining the moving width of the upper and lower sides are formed.

즉, 헤드레스트(10)의 내부에 설치되는 지지대(1)의 단부가 시트백(11)의 가이드홈에 삽입되어 고정되고, 푸쉬노브(3)와 연결되어 있는 걸림수단에 의해 단속된다.That is, the end of the support 1 installed in the headrest 10 is inserted into the guide groove of the seat back 11 and fixed, and is interrupted by the locking means connected to the push knob 3.

그리고, 사용자의 필요에 의해 푸쉬노브(3)를 누르게 되면 걸림수단이 해제되어 일정한 길이만큼 움직임을 갖는 것이다.Then, when the push knob 3 is pressed by the user's need, the locking means is released to have a certain length of movement.

따라서, 헤드레스트는 탑승자의 머리부분을 지탱할 수 있게 되어 있어 휴식을 취하거나, 추돌등의 사고에 탑승자의 신체부위를 보호하는 것이다.Therefore, the headrest is able to support the head of the occupant to rest or protect the body part of the occupant in the event of a collision or the like.

상기와 같이 구성된 종래의 자동차 시트의 헤드레스트는 상하방향으로만 이동이 가능하므로 휴식을 취하기 위하여 시트를 뒤로 젖히게 되면 상기 헤드레스트에 의해 목이 앞쪽으로 꺽여있게 되어 편안함을 제공하지 못하였다.The headrest of the conventional car seat configured as described above is movable only in the up and down direction, so when the seat is folded back to rest, the neck is bent forward by the headrest to provide no comfort.

또, 상하 방향으로만 이동되는 헤드레스트는 체형이 다양한 사용자들의 욕구를 충족하지 못하며, 추돌등의 사고에 고정된 헤드레스크에 의해 탑승자의 안전을 보장하지 못하였다.In addition, the headrest that is moved only in the up and down direction does not satisfy the needs of various users of the body shape, and the head restrained by accidents such as collision did not guarantee the safety of the occupants.

본 발명의 목적은, 헤드레스트가 상하방향으로의 이동뿐 아니라 전후방향으로의 회전도 가능하도록하여 추돌등의 사고에 타격을 분산시켜주는 자동차 시트의회전가능한 헤드레스트를 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a rotatable headrest of an automobile seat that disperses a hit in an accident such as a collision by allowing the headrest to move in the vertical direction as well as to move in the vertical direction.

본 발명의 다른 목적은, 탑승자가 휴식등을 취하게 될때, 탑승자에게 편안한 자세를 유지토록 한 자동차 시트의 회전가능한 헤드레스트를 제공하는 데 있다.Another object of the present invention is to provide a rotatable headrest of a car seat which allows the occupant to maintain a comfortable posture when the occupant takes a break or the like.
