Abstract

The invention provides a type of all-terrain vehicle seat installation structure; it includes the cab frame and the seat backrest arranged on the frame; the back mounting side of the seat backrest includes the first mounting part and the second mounting part arranged up and down respectively. The first mounting part includes the upper support frame located at the upper end of the frame; the installation hole is arranged on the upper support frame; the installation pin inserted into the installation hole is extended out of the seat backrest. The second mounting part includes the lower support frame located at the lower end of the frame; the lower end of the seat backrest is provided with the installation buckle mounted on the lower support frame. The top of the seat backrest is limited by the installation pin being inserted into the installation hole; the seat backrest is supported by the bottom installation buckle; the top of the seat backrest is limited by the inserting installation structure of the installation pin and the installation hole to avoid the seat backrest moving up and down on the frame, so the stability of the seat installation structure of the all-terrain vehicle is improved. The invention also provides a type of all-terrain vehicle provided with the seat installation structure of the all-terrain vehicle as described above.

First claim

The invention claimed is:

1. A seat installation structure for an all-terrain vehicle comprising:
a cab frame having an upper support frame and a lower support frame, with an installation hole in the upper support frame;
a seat backrest arranged on the cab frame;
an installation pin extending out of a back mounting side of the seat backrest, the installation pin being inserted into the installation hole; and
an installation buckle on the back mounting side of the seat backrest, the installation buckle supporting the weight of the seat backrest from the lower support frame by wrapping at least partially around an upper side of the lower support frame, such that the installation pin and the installation buckle jointly secure the seat backrest to the cab frame.

2. The seat installation structure according to claim 1 , wherein a bottom end of the lower support frame comprises a support bar that provides radial support for the installation buckle, the installation buckle having a clamping opening for placement onto the support bar when the seat back is installed onto the cab frame.

3. The seat installation structure according to claim 2 , comprising at least two installation buckles arranged side to side in the said seat backrest width direction, wherein clamping openings of the installation buckles both open downwards.

4. The seat installation structure according to claim 2 , wherein the lower support frame includes a first mounting column and a second mounting column arranged at ends of the support bar, wherein upper ends of the first mounting column and the second mounting column are fixed to a horizontally extending part of the upper support frame.

5. The seat installation structure according to claim 1 , wherein the installation pin extends out of a support base projecting out of an upper end of the seat backrest, the support base making contact with the said upper support frame, with the installation pin being located where the support base contacts the upper support frame.

6. The seat installation structure according to claim 5 , wherein the installation pin comprises an installation pin body fixed in the support base and a limit head at an end of the installation pin body, the limit head having a conical shape, the maximum outer diameter of the limit head being not less than the inner diameter of the installation hole.

7. The seat installation structure according to claim 5 , further comprising a cushioning pad extending through the installation hole with the installation pin, the cushioning pad comprising a cushioning part between a first annular ear and a second annular ear, wherein the first annular ear makes contact with an inner wall surface of the upper support frame around the installation hole, and wherein the second annular ear makes contact with an outer wall surface of the upper support frame around the installation hole.

8. The seat installation structure according to claim 7 , wherein the outer diameter of the first annular ear is smaller than the outer diameter of the second annular ear.

9. The seat installation structure according to claim 1 , wherein the upper support frame is formed from a tube, with the installation hole being through a wall of the tube.

10. A seat installation structure for an all-terrain vehicle comprising:
a cab frame having a horizontally extending upper support frame with an installation hole therein and a lower support frame hanging from the upper support frame, the lower support frame having a first mounting column and a second mounting column fixed at their upper ends to the upper support frame with a horizontally extending support bar running between the first and second mounting columns;
a seat backrest arranged on the cab frame;
an installation pin extending out of a back mounting side of the seat backrest, the installation pin being inserted into the installation hole; and
an installation buckle on the back mounting side of the seat backrest, the installation buckle supporting the weight of the seat backrest from the horizontally extending support bar of the lower support frame, such that the installation pin and the installation buckle jointly secure the seat backrest to the cab frame.
