이하 첨부된 도면을 참조하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
제1도 내지 제5도를 참조하여 설명하면, 시트백(10) 상단의 좌우 양측에 승객의 어깨부위를 감싸주어 지지하는 어깨받이(20)를 각각 설치한다. 이같은 어깨받이(20)의 일측 저면에는 높이조절용 바아(bar:25)가 부착되되, 상기 높이조절용 바아(25)는 내부가 중공인 관 형태이며, 그 외면에는 내측으로 관통되는 고정홀(36)이 형성된다.Referring to FIGS. 1 to 5, the shoulderrests 20 are provided on the left and right sides of the upper end of the seatback 10 to support and surround the shoulders of the passengers. Height adjustment bar (bar: 25) is attached to the bottom of one side of the shoulderrest 20, the height adjustment bar (25) is in the form of a hollow tube, the outer surface of the fixing hole 36 penetrates inward Is formed.
이같은 어깨받이(20)의 높이조절용 바아(25) 하부로 어깨받이 지지봉(30)의 상부가 끼워지며, 상기 어깨받이 지지봉(30)의 상부에는 하방향으로 복수개의 걸림홈(32)이 형성된다.The upper portion of the shoulder support bar 30 is inserted into the lower bar 25 for height adjustment of the shoulder rest 20, a plurality of engaging grooves 32 are formed in the upper direction of the shoulder support bar 30. .
또한 상기 어깨받이 지지봉(30)의 하단부에는 사각의 결합부(34)가 형성된다. 그리고, 높이조절키이(72)가 상기 높이조절용 바아(25)의 고정홀(36)과 어깨받이 지지봉(30)의 하나의 걸림홈(32)을 차례로 관통하도록 끼워짐으로써, 높이조절용 바아(25)와 어깨받이 지지봉(30)이 상호 결합되는 것이다.In addition, a square coupling portion 34 is formed at the lower end of the shoulder support bar 30. Then, the height adjustment key 72 is inserted so as to pass through the fixing hole 36 of the height adjustment bar 25 and one locking groove 32 of the shoulder support bar 30 in turn, the height adjustment bar (25) ) And shoulder support bar 30 will be mutually coupled.
또한, 상기 어깨받이 지지봉(30)은 시트프레임(60)에 고정 설치된 가이드 봉 (70)에 삽입되게 되며, 그 하단부는 상기 가이드 봉(70)을 관통하여 외측으로 인출되 어진다.In addition, the shoulder support rod 30 is inserted into the guide rod 70 is fixed to the seat frame 60, the lower end is drawn out through the guide rod 70.
상기와 같이 가이드 봉(70)의 외측으로 인출된 어깨받이 지지봉(30)의 하단부 에는 평판캠(46)이 고정 결합되며, 상기 평판캠(46)의 후방부에 형성된 사각홀(46a) 에 상기 어깨받이 지지봉(30)의 결합부(34)가 끼워져 결합되는 것이다. 이러한 상기 어깨받이 지지봉(30)과 평판캠(46)의 결합은 제4도에서와 같이 강제끼움되어도 무방하지만, 그 밖에도 제2도에서와 같이 상기 사각홀(46a)을 관통하는 결합부(34)가 너트에 의해 고정되도록 하여도 무방하다. 또한 상기 어깨받이 지지봉(30)이 삽입되어 있는 가이드 봉(70)은 시트프레임(60)에 고정 설치되어 있으므로, 상기 평판캠(46)의 회동시 상기 어깨받이 지지봉(30)이 힌지축의 기능을 하는 것이다.The flat plate cam 46 is fixedly coupled to the lower end of the shoulder support bar 30 drawn out to the outside of the guide rod 70 as described above, the square hole 46a formed at the rear of the flat plate cam 46 Coupling portion 34 of the shoulder support bar 30 is fitted to be coupled. The coupling between the shoulder support bar 30 and the flat cam 46 may be forced fit as in FIG. 4, but in addition, the coupling part 34 penetrating the square hole 46a as in FIG. ) May be fixed by a nut. In addition, since the guide rod 70 into which the shoulder support rod 30 is inserted is fixedly installed in the seat frame 60, the shoulder support rod 30 serves as a hinge shaft when the flat cam 46 is rotated. It is.
그리고 상기 평판캠(46)의 전방부 일측에는 케이블선(56)의 일측 단부가 연결 되며, 그 타측에는 상기 시트프레임(60)에 장착된 지지대 브라켓트(66)에 고정 설치 되어있는 리턴스프링(68)이 접속체결된다.And one end of the cable line 56 is connected to one side of the front portion of the flat cam 46, the other side of the return spring is fixed to the support bracket 66 mounted on the seat frame 60 ) Is connected.
그리고, 상기 평판캠(46)에 연결된 케이블선(56)은 시트프레임(60)의 중앙부에 부설된 선지지부재(58)를 통해 작동레버(50)에 체결되어 작동레버(50)의 동력을 평판 캠(46)에 전달한다.In addition, the cable line 56 connected to the flat plate cam 46 is fastened to the operating lever 50 through the pre-support member 58 attached to the center of the seat frame 60 to power the operating lever 50. The flat cam 46 is transferred.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
승객이 시트에 착석한 후 시트 쿠션의 일측에 설치된 작동레버(50)를 상방향으로 당기게 되면, 작동레버(50)에 연결된 케이블선(56)이 당겨지게 된다. 이같이 케이블선(56)이 당겨지면 평판캠(46)은, 리턴스프링(68)의 탄성력을 이기고, 가이드 봉 (70)에 끼워져 힌지축 역할을 하게되는 어깨받이 지지봉(30)을 중심으로 내측 방향으로 수평회동하게 된다. 이때 상기 평판캠(46)과 고정되는 어깨받이 지지봉(30)이 연동하여 회전하므로, 상기 어깨받이 지지봉(30)에 결합된 높이조절용 바아(25)가 회전하게된다. 이에 따라 상기 높이조절용 바아(25)와 결합된 어깨받이(20)가 내측으로 회전되면서 승객의 어깨를 감싸 지지하게 된다.When the passenger is seated on the seat and pulls the operation lever 50 installed on one side of the seat cushion upward, the cable wire 56 connected to the operation lever 50 is pulled. In this way, when the cable wire 56 is pulled, the flat cam 46 overcomes the elastic force of the return spring 68 and is inserted into the guide rod 70 and is moved inward with respect to the shoulder support rod 30 that serves as a hinge axis. It will rotate horizontally. At this time, since the shoulder support bar 30 fixed to the flat cam 46 rotates in conjunction, the height adjustment bar 25 coupled to the shoulder support bar 30 is rotated. Accordingly, the shoulderrest 20 coupled with the height adjusting bar 25 is rotated inward to support and surround the shoulder of the passenger.
그리고, 승객이 어깨받이(20)를 어깨로부터 해제하고자 할 경우에는 작동레버 (50)를 하방향으로 내린다. 상기 작동레버(50)는 하향되면서 케이블선(56)을 당기던 힘을 해제하게 되고, 케이블선(56)은 느슨한 상태가 된다. 이에 따라 평판캠(46)이 리턴스프링(68)의 탄성력에 의해 원래의 상태로 회전되게 된다. 이때 어깨받이(20) 역시 위에서 서술된 어깨받이(20)가 내측으로 회전되는 동작과 동일하게 동작되면서 승객의 어깨로부터 벗어나 원래의 위치로 복귀되는 것이다.In addition, when the passenger wants to release the shoulder rest 20 from the shoulder, the operating lever 50 is lowered downward. The operation lever 50 is released while releasing the force pulling the cable wire 56, the cable wire 56 is in a loose state. Accordingly, the flat cam 46 is rotated to its original state by the elastic force of the return spring (68). At this time, the shoulder rest 20 is also returned to its original position away from the shoulder of the passenger while the same operation as the shoulder rest 20 described above is rotated inward.
또한, 어깨받이(20)와 높이를 승객의 체형에 맞도록 교정하고자 할 경우에는, 높이조절키이(72)를 어깨받이(20)의 높이조절용 바아(25)로부터 분리하여 어깨받이 지지봉(30)과 어깨받이(20)의 결합을 해제한 후에, 상기 어깨받이(20)를 원하는 높이에 위치시킨다. 그리고 상기 높이조절키이(72)를 상기 높이조절용 바아(25)의 고정홀 (36) 및 어깨받이 기지봉(30)의 걸림홈(32)에 차례로 끼워지도록 결합하며, 이때 상 기 걸림홈(32)은 위에서 서술한 최초의 걸림홈(32)이 아닌 조절된 높이에 위치한 걸 림홈(32)이다. 이같은 방식으로 상기 어깨받이(30)는 높이가 조절된 상태로 고정되는 것이며, 이에 따라 승객이 자신의 체형이나 탑승자세 등에 따라 어깨받이(20)의 높낮이를 고정할 수 있는 것이다.In addition, when the shoulderrest 20 and the height are to be corrected to fit the passenger's body type, the height adjustment key 72 is separated from the height adjusting bar 25 of the shoulder rest 20 to support the shoulder rest 30. After releasing the engagement with the shoulderrest 20, place the shoulderrest 20 at the desired height. And the height adjustment key 72 is coupled to be fitted in turn into the locking hole 36 of the fixing hole 36 and the shoulder rest base bar 30 of the height adjustment bar 25, wherein the locking groove 32 ) Is a locking groove 32 located at an adjustable height, rather than the first locking groove 32 described above. In this way, the shoulder rest 30 is fixed in a state where the height is adjusted, and thus the passenger can fix the height of the shoulder rest 20 according to his or her body shape or boarding attitude.
이상 설명에서 알 수 있는 바와같이, 본 고안은 승객의 안전을 위해 사용되던 허리및 가슴보호벨트 대신에 어깨를 감싸주는 어깨받이를 착용하므로서 사용이 간편하고 충격발생시 어깨부위를 지지해 주므로 효과적으로 부상을 방지할 수 있다.As can be seen from the above description, the present invention is easy to use and supports the shoulder part in the event of an impact by wearing a shoulder restraint instead of the waist and chest protection belts used for the safety of passengers, thereby effectively injuring the injured body. It can prevent.
