Abstract

The utility model relates to a damping seat for vehicles. Four legs of the seat are made into sleeve type legs. A lower sleeve is provided with a spring inside. An upper sleeve is sheathed in the lower sleeve, and the lower end face of the upper sleeve contacts the upper end face of the spring in the lower sleeve. The utility model can effectively reduce uncomfortableness on people caused by the vibration of vehicles, prevents a people's head from hitting a vehicle roof, and increases riding comfortableness. The utility model is suitable for various vehicles, particularly large-sized buses.

Description

The vibration damping automotive seat

The utility model relates to a kind of seat, especially a kind of vibration damping automotive seat.

Seat on the present automobile, its chair pin is that rigidity connects with connecting of automobile, the vibration that automobile causes owing to pavement roughness in motion is directly delivered to the people who is sitting on the chair, make the people be difficult to bear, What is more, because automobile vibration and people's vibration is asynchronous, people's head can be run on the car roof sometimes, thereby hits the pain head.

The purpose of this utility model is to provide a kind of vibration damping automotive seat.

The utility model is to realize above-mentioned purpose like this: four pin of seat are made sleeve-type, spring is housed in the lower sleeve, the spring upper end that upper bush is enclosed within the lower sleeve and the lower surface of upper bush and lower sleeve are interior contacts, and plays damping of vibrations like this.

Because the utility model adopts sleeve-type chair pin, damper spring is housed in the lower sleeve, so to people's influence, head and the roof avoided vibrating when big because of the asynchronous people who causes of people and automobile vibration bumped against, and have increased ride comfort when the utility model can effectively alleviate automobile vibration.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail.

Fig. 1 is the part sectional view of the utility model structure.

With reference to Fig. 1, part 1 is the seat back of the body, it places on the chair frame 2, and chair frame 2 has 4 sleeve pin, with reference to partial cutaway part among Fig. 1, in the lower sleeve 9 of sleeve pin spring 8 is housed, upper bush 5 is loaded in the lower sleeve 9, and its lower surface contacts with the upper end of spring 8, can not skid off lower sleeve 9 along the upper and lower slip of lower sleeve 9 inwalls in order to make upper bush 5, the bottom of upper bush 5 has an elongated slot 6, and elongated slot 6 does not connect the bottom of upper bush 5 so that cooperate with the gear screw 7 on lower sleeve 6 tops; Chair frame 2 is installed for convenience, and the bottom of the pin head 3 that is fixedly connected with chair frame 2 is installed in the endoporus of upper bush 5, and fixing with screw 4, like this when vibration, upper bush 5 will be along the upper and lower slip of the inwall of lower sleeve 9, and because of the effect of gear screw 7, upper bush 5 is unlikely and skids off lower sleeve 9.
