Description

[Detailed explanation of the invention] This invention relates to a device for installing seats on tractors, etc. In order for the driver to take a posture suitable for various tasks, the driver can move the seat forward, backward, left and right, or in a slightly rotated position. The object of the present invention is to provide a seat mounting device that can be moved and adjusted to a position convenient for the user.

Examples of this invention will be described below based on the drawings.

1 is a seat, 2 is a pair of left and right brackets made of downward U-shaped plates attached to the front bottom of the seat, and a support shaft 3 is located in front of the bracket 2, for example, 5a and 5b or 6a and 6b. As shown in the figure, a locking support shaft 4 having left and right locking portions 5 cut out at a plurality of locations at desired intervals is fixedly installed behind the bracket 2 and between the left and right brackets 2, respectively.

Reference numeral γ denotes a seat support frame made of an upward U-shaped plate that is attached to the vehicle body.Elongated holes 9 forming guide grooves in the front and rear direction are punched in a pair of left and right side walls 8 of the seat support frame, and the guide grooves extend in the longitudinal direction. The front and rear locking portions 10 are attached at multiple locations by pressing buttons at predetermined intervals.
is recessed.

The support shaft 3 is inserted into the elongated hole 9, and the seat 1 can be freely rotated around the support shaft 3 as shown by the arrow in FIG. Furthermore, it can also be slid in the left and right directions along the support shaft 4 as shown by the arrow in FIG.

The seat is fixed in the front, rear, left and right positions by fitting the left and right locking portions 5 cut out in the locking support shaft 4 with the front and rear locking portions 10 recessed in the seat support frame 6.

Reference numeral 11 denotes a seat support section made of an elastic body such as rubber.

This idea is constructed as described above, and the second section is as follows.
．． The operation will be explained based on Figure 3.4.

When moving the seat 1 in the longitudinal direction, lift the rear part of the seat around the support shaft 3 as shown by arrow A in FIG. After releasing the engagement with the front and rear locking parts 10 recessed in the left and right side walls of the frame, the support shaft 3 is moved back and forth along the elongated hole 9 to a desired position, and as shown by the arrow B in FIG. When the seat 1 is returned to its original position and the left and right locking portions 5 and the front and rear locking portions 10 are fitted together, the seat 1 is fixed at a desired position.

Also, when moving seat 1 to the left or right, the third
After lifting the seat 1 as shown by the arrow A in the figure and releasing the engagement between the left and right locking parts 5 and the front and rear locking parts 10, the seat 1 is moved left and right along the support shaft 3 as shown by the arrow in FIG. The seat 1 can be moved in the left-right direction by returning the seat 1 as shown by arrow B in FIG. can.

Furthermore, the seat 1 can be adjusted to a slightly rotated position by similarly lifting the rear part of the seat and swinging it left and right as shown in FIG. 4, and returning the seat 1 as shown by arrow B in FIG.

As described above, this invention has an extremely simple structure, is free from failure, can be provided at a low cost, and can reliably adjust the seat's forward, backward, leftward, rightward, and swivel positions through simple engagement and disengagement operations.
