Abstract

PURPOSE: A shock absorbing device for a seat of a vehicle with a gas spring and a gas cylinder is provided to adjust buffer force by pushing or pulling a lever simply, to adjust a height of the seat and to use a soft shock absorbing device by not generating noise in compression and tension. CONSTITUTION: A shock absorbing device for a seat of a vehicle has a gas spring(11) and a gas cylinder(12). The gas spring is installed to a rear end of a lower plate(16) to be connected to a connecting flange(22) with a shaft(21). The gas spring absorbs shock and noise in compression and tension without mechanical friction. The gas cylinder is installed to a front end of an upper plate to be connected to a connecting flange(26) with a shaft(25). A button(24) is installed to the gas cylinder to adjust a length of a rod(23). A lever(27) is combined together to operate the button easily when the gas cylinder is combined. A flange(30) is installed to tips of rods(28) of the gas spring and the gas cylinder to be combined each other with a shaft(29). A roller(31) is inserted to the flange to support the rod of the gas spring horizontally. A plate(32) is installed to the lower plate to move the roller freely. A moving surface(32a) of the roller is protruded from the plate. Thereby, buffer force is adjusted by pushing and pulling the lever, and a height of the seat is adjusted at the same time.

The shaft 33 is coupled to allow the sliding movement in the lateral direction, and the free rotating roller 20 is installed and installed on the guide rails 13 and 14 of the upper plate 15 and the lower plate 16 in the "c" shape. .

하판(16)의 후방 단부의 중앙에는 기존의 완충장치에 사용된 인장스프링(1)과 피스톤 실린더(2)의 역할을 대신할 수 있는 즉, 기계적인 마찰이 없고 압축 및 인장시 소음이나 충격을 흡수하는 가스스프링(11)과 이를 하판(16)과 축(21) 결합할 수 있도록 연결프랜지(22)를 하판(6)에 착설하여 결합한다.In the center of the rear end of the lower plate 16 can replace the tension spring (1) and the piston cylinder (2) used in the existing shock absorber, that is, there is no mechanical friction and noise or shock during compression and tension The coupling flange 22 is installed on the lower plate 6 so as to be coupled to the gas spring 11 and the lower plate 16 and the shaft 21 to absorb.

상판(15)의 전방 단부의 중앙에는 기존의 완충장치에서 인장스프링(1)의 인장력을 조절할 수 있는 조절나사(3)를 대체 할 수 있는 즉, 로드(23)의 길이가 조절되고 이를 제어할 수 있는 버튼(24)이 구비된 가스실린더(12)와 이를 상판(15)과 축(25) 결합할 수 있도록 연결플랜지(26)를 상판(15)에 착설하여 결합한다. 이때 버튼(24)의 조작을 쉽게 하기 위해 레버(27)도 함께 축(25) 결합한다.In the center of the front end of the upper plate 15 can replace the adjustment screw 3 that can adjust the tension force of the tension spring (1) in the existing shock absorber, that is, the length of the rod 23 is adjusted and control Gas cylinder 12 having a button 24 and a coupling flange 26 installed on the upper plate 15 to be coupled to the upper plate 15 and the shaft 25 are coupled to each other. At this time, the lever 27 is also coupled to the shaft 25 to facilitate the operation of the button 24.

상기 가스스프링(11)의 로드(28)와 가스실린더(12)의 로드(23) 끝단에는 서로 간 축(29) 결합할 수 있는 플랜지(30)가 구비되고 그 플랜지(30) 안쪽에는 가스스프링(11)의 로드(28)가 수평 지지될 수 있도록 롤러(31)를 축(29) 삽입한다. 이때 하판(16)에는 롤러(31)의 자유회동이 가능하도록 플레이트(32)가 설치되어 있으며 이 플레이트(32)는 롤러(31)의 운동경로부분이 튀어나와 롤러(31)와의 운동면(32a)을 형성한다.The end of the rod 28 of the gas spring 11 and the rod 23 of the gas cylinder 12 is provided with a flange 30 which can be coupled to the shaft 29 between each other, the gas spring inside the flange 30 The roller 31 is inserted into the shaft 29 so that the rod 28 of the (11) can be horizontally supported. At this time, the lower plate 16 is provided with a plate 32 to enable the free rotation of the roller 31, the plate 32, the movement path portion of the roller 31 is protruding the movement surface 32a with the roller 31 ).

이하 본 발명의 작동 예를 설명한다.Hereinafter will be described an operation example of the present invention.

제 2도는 본 발명의 전체 사시도 이며 레버(27)를 밀거나 당김으로써 가스실린더(12)의 버튼(24)을 작동시켜 가스실린더(12)의 로드(23) 길이를 줄이거나 늘릴수 있게 되어있다. 이때 가스실린더(12)의 로드(23)는 가스스프링(11)의 로드(28)와 연결되어 있어서 상판(15)에 외력이 가해지지 않았을 경우 상판(15)의 높이는 가스실린더(12)의 로드(23)길이와 연관되어 결정되어지며 제 3도는 가스실린더(12) 로드(23)의 길이에 따라 달라진 상판(15)의 높이를 나타낸다.2 is an overall perspective view of the present invention, and by pushing or pulling the lever 27, the button 24 of the gas cylinder 12 can be operated to reduce or increase the length of the rod 23 of the gas cylinder 12. . At this time, the rod 23 of the gas cylinder 12 is connected to the rod 28 of the gas spring 11 so that when no external force is applied to the top plate 15, the height of the top plate 15 is the rod of the gas cylinder 12. (23) Determined in relation to length and FIG. 3 shows the height of the top plate 15 depending on the length of the gas cylinder 12 rod 23.

또한, 가스실린더(12)의 로드(23)길이가 일정 이상으로 늘어나면 가스스프링(11)의 로드(28)가 줄어들어 가스스프링(11)의 탄성력이 증가하게 되고 반대로 가스실린더(12)의 로드(23)길이가 일정 이상으로 줄어들면 가스스프링(11)의 로드(28)가 늘어나 가스스프링(11)의 탄성력은 감소하게 되며 이로써 본 발명의 완충장치는 완충력을 조절할 수 있다. 이것은 제 4도에서 보여진다.In addition, if the length of the rod 23 of the gas cylinder 12 is increased by more than a predetermined length, the rod 28 of the gas spring 11 is reduced, so that the elastic force of the gas spring 11 is increased, and conversely, the rod of the gas cylinder 12 is increased. (23) If the length is reduced to a predetermined value or more, the rod 28 of the gas spring 11 is extended, so that the elastic force of the gas spring 11 is reduced, whereby the shock absorber of the present invention can adjust the buffering force. This is shown in Figure 4.

상기와 같은 작동예를 응용하여 사용자는 자신의 조건에 맞게 완충장치의 완충력과 높이를 조절할 수 있다.By applying the above operation example, the user can adjust the buffering force and height of the shock absorber according to their conditions.

상기와 같이 구성된 본 발명은 차량용 좌석에 가해지는 진동 및 충격을 흡수하거나 완충함에 있어서 완충력을 조절할 필요가 있을 시에 레버(27)를 누르거나 당기는 간단한 조작만으로 완충력을 조절할 수 있으며 이와 동시에 좌석의 높이를 조절할 수 있는 장점이 있다.The present invention configured as described above can adjust the cushioning force by simply pressing or pulling the lever 27 when it is necessary to adjust the buffering force in absorbing or cushioning the vibration and shock applied to the vehicle seat and at the same time the height of the seat There is an advantage that can be adjusted.

또한, 가스스프링(11)의 작동 특성상 기계적인 마찰이 없어 압축이나 인장시 소음이 발생하지 않으므로 인장스프링(1)을 사용하는 차량용 좌석완충장치보다 작동시 정숙한 장점이 있다.In addition, there is no mechanical friction due to the operating characteristics of the gas spring 11, there is no noise generated during compression or tension, there is a quiet advantage when operating than the vehicle seat buffer device using the tension spring (1).
