Embodiment Construction

[0022] The buffer force adjusting device of the present invention is composed of upper and lower frames 2, 3 and the X-shaped connecting rod 4 connecting them, and an air spring 5 and a buffer 6 are arranged between these frames. The air spring is the load supporting the chair on the upper frame 2, and the damper 6 plays the role of easing the vibration amplitude of the air spring and making the chair not violently bump.

[0023] The interior of the cylinder of the buffer 6 of the present invention is filled with oil or gas, and the valves in the interior control the flow of the oil or gas. The protruding connecting rod 7 in front of the cylinder is combined with the buffer bracket 6a through the upper frame 2 .

[0024] The connecting rod 7 is a hollow pipe, and the flow adjustment pin 8 inside controls the valve. A part of the flow adjustment pin 8 is exposed to the outside of the connecting rod 7, and an iron wire 9 having a spring 9b is connected to this part. The front e...

Abstract

The present invention provides a buffering power adjusting apparatus used for vehicle chairs. Problems to be resolves are as follows: after the buffering mechanism mounted at lower part of the vehicle chairs calculates weight of chairs and driver weight in average, the buffering power is maintained constant, then one will feel he is falling when the vehicle runs at uneven running surfaces. The improved points in accordance with the present invention are as follows: frontends of wires are fixed at the upper frame through wire bracket, rear ends of wires are connected to the control lever, the piston of wires is connected to an adjusting pin, the control lever fixed at the upper frame is equipped with circular arc shaped hooking flute, and the upper frame is equipped with a hooking pin for elastically hooking the flute. The present invention possesses the beneficial effects as follows: pressing the rotary control lever can adjust the buffering power; when a vehicle runs at a road surface without stones coated, the buffer is adjusted softly to improve the buffering performances. The present invention is suitable for application in vehicle seats.

Description

【Technical field】 [0001] The present invention relates to a device for adjusting the cushioning force of a motor vehicle chair. More specifically, the driver can adjust the buffering force of the buffer arranged at the lower part of the chair according to the road surface and absorb the bumpy waves of the road surface. 【Background technique】 [0002] The function of the buffer device generally installed at the lower part of the vehicle chair is that when the vehicle is running on an uneven road surface, it can absorb the impact transmitted to the chair, and can stably maintain the height of the chair to facilitate the driver's driving. figure 1 It is a side view of the driver's seat. The seat 1 is fixed on the upper frame 2, and an X-shaped connecting rod 4, an air spring 5 and a buffer 6 for easing the impact are arranged between the upper and lower frames 2 and 3. [0003] The shock absorber 6 suppresses the sudden up and down movement and impact of the air spring 5, maint...
