Abstract

The utility model relates to an upper chair on a motor vehicle, particularly a chair of a driver on a tractor. The utility model is mainly composed of a bracket and a floating frame, wherein, two vertical flat plates on the front end of the floating frame are respectively pivoted with two side vertical plates of the bracket, the inner side of the rear end of the floating frame is provided with two rear inner reeds and two rear outer reeds which are all spaced, and the outer side of the front end of the floating frame is respectively provided with two front outer reeds. Thus, the utility model can relieve vibration in multiple directions, a driver can feel comfort, and the utility model has simple structure simultaneously.

Description

The trac. shock-absorbing seat

The utility model relates to seat on a kind of self-propelled vehicle, especially refers to driver's seat on the trac..

At present, the seat of trac. just increases cushion course, reduce the influence of the vibration of trac. to chaufeur, but owing to be not provided with leaf spring on the trac. crossbeam, mostly again at uneven road traveling, it is quite severe to jolt, and chaufeur is sitting on the trac. for a long time and works, and often stands jolting of many trac.s.

In view of this, what a kind of coil spring by diverse location of the purpose of this utility model proposition made up can support the shock-absorbing seat of seat around the floating shelf of a fulcrum deflection, can absorb or reduce the multi-aspect vibration from trac..

The purpose of this utility model is achieved in that it mainly is made up of support and floating shelf, front end two perpendicular dull and stereotyped being articulated in respectively on the both sides riser of support of floating shelf, the floating shelf rear inside is provided with the outer spring of interior spring in two backs and two backs at interval, and outer spring before being respectively equipped with two outside its front end.

Above-mentioned floating shelf is to form by connecting a transverse slat between the plane, top, grillage rear end, both sides.

Above-mentioned support is horizontal trough plate.

Spring, the outer spring in back and preceding outer spring are all coil spring in the above-mentioned back.

Owing to adopt such scheme: can slow down multidirectional vibration, chaufeur is felt comfortably cool, structure is also simple simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments scheme drawing.

Fig. 2 the utility model exemplary embodiments, the A-A cross-sectional schematic of Fig. 1.

Among the figure: 1, support 2, floating shelf 21, both sides grillage 22, transverse slat

23, spring 24, the outer spring 25 in back, preceding outer spring 3, seat cushion 4, adapter plate in the back

Present embodiment mainly is made up of support 1 and floating shelf 2, and as shown in Figure 1, 2, wherein: support 1 is with the horizontal trough plate of flute profile bottom surface bolt together on the adapter plate on the trac. 4, is respectively equipped with through hole on the riser of both sides.

Floating shelf 2 is to be made of spring 23, the outer spring 24 in back and preceding outer spring 25 in both sides grillage 21, a transverse slat 22, the back; Bolt together one transverse slat 22 between the plane, top, rear end of both sides grillage 21, and on the perpendicular flat board of the front end of both sides grillage 21 through hole is arranged and be articulated in respectively with bolt on the through hole of support 1 both sides riser, make floating shelf 2 integrally rotate (among a small circle) relative to support 1, between transverse slat 22 and adapter plate 4, be provided with two compartment of terrains vertically in the back spring 23 (coil spring) both sides grillage 21 rear inside respectively and be provided with the outer spring 24 (coil spring) in vertical back between the adapter plate 4, in above-mentioned two backs human buttock position on the outer spring 24 support seat cushions 3 behind the spring 23 and two; Outer spring 25 (coil spring) before being respectively equipped with vertically between the both sides grillage 2 front ends outside and the adapter plate 4 is supported human body thigh place outer fix on the seat cushion 3.

Present embodiment is in sum:

Since floating shelf 2 be can swing pivoted body, all be supported on the trac. adapter plate 4 at diverse location again with coil spring, therefore, can not only absorb the vibration of trac. vertical direction, and the vibration of direction of tilt can absorb also, chaufeur is felt comfortably cool.
