Description

[Detailed Description of the Invention] There are various types of height-adjustable automobile seats. (For example, Kimiaki Sane
(Refer to Publication No. 52-35624) In contrast, the idea presented here relates to a height-adjustable bus driver's seat. The explanation is as follows.

That is, a top base 2 is attached on top of the base body 1, and a seat body 4 is attached thereon via a moving rail 3 for longitudinal adjustment. The base main body 1 has an outer cylinder 5 fixed to a floor and an inner cylinder 6 sliding inside the outer cylinder 5, and a top base 2 is fixed to the inner cylinder 6 by welding. The inner cylinder 6 is held at a height relative to the outer cylinder 5 by an internal biasing spring or a sealed fluid.

In addition, on the bracket 7 provided on the Atsupa base 2,
A lock arm 9 to which a handle 8 is welded is pivotally supported, and a lock pin 10 provided at the end of the lock arm 9 is pushed into several lock grooves 12 provided along the outer cylinder 5 by the bias of a compression spring 11. It is designed to engage either of the

To move the seat body 4 up and down with respect to the base body 1, the handle 8 is grasped against the bias of the spring 11, the lock arm 9 is rotated, and the lock pin 10 is pulled out from the lock groove 12. After setting the height of the inner tube 6 to the desired position relative to the outer tube 5, the handle 8 is released. Then, the lock pin 10 will fit into the appropriate lock groove 12 and will be biased by the spring 11 so as not to come out, so that this height position will be reliably maintained.

Therefore, in this structure, the height of the seat body can be adjusted only by the number of stages corresponding to the number of lock grooves 12 arranged in the height.

On the other hand, the present invention allows the height to be adjusted over a wider range, by creating a step difference in height between the base body attachment part of the Atsupa base and the seat body attachment part. It is configured so that it can be installed and used by flipping it over.

Next, its structure will be explained using an embodiment of the present invention shown in FIG.

This uses an Atsupa base 13 instead of the Atsupa base 2 of the conventional example, and a mounting plate 14 is provided on the top of the base body 1 of the conventional example, and the Atsupa base 13 and the mounting plate 14 are made detachable by bolts 15. .

Then, in the Atsupa base 13, the mounting plate 14
The mounting portion 13a for the rail and the mounting portion 13b for the moving rail (not shown) are formed to have a step difference in height. Further, the mounting portion 13b and the moving rail are made detachable by bolt connection.

Therefore, when the moving rail is removed from the Atsupa base 13, the Atsupa base 13 is removed from the mounting plate 14, and the Atsupa base 13 is turned upside down and installed on the mounting plate 14, the mounting part 13b to which the moving rail is attached becomes the state 13b'. .

That is, the height of the seat body via the moving rail is 2 times the height difference between the mounting portion 13a and the mounting portion 13b.
Doubles are formed differently. Then, attach the Atsupa base 13 to the mounting part 13b or the inverted mounting part 13.
If the lock pin 10 and the lock groove 12 are engaged with each other in the state b', the height can be adjusted over a wide range.

Since the present invention is constructed as described above, its effects can be compared with those of the conventional structure as follows.

(b) In the conventional model, the Atsupa base is welded and fixed to the base body, so the number of adjustment steps is limited.The height of the base body has to be adjusted to accommodate the different types of cars equipped with this seat and the physical differences of the drivers. The only way to deal with this was to change it and provide a locking groove.

(b) Therefore, it was necessary to prepare many types of base bodies, and it was complicated to manufacture and respond to user requests.

(c) Since the present invention can be used by reversing the Atsupa base, the adjustment range is widened, and it is possible to easily accommodate differences in car models and physical differences between drivers.

(d) Therefore, there is no need to prepare many types of base bodies and a standard base body can be used.
Manufacturing costs become cheaper.

(e) Furthermore, since the Atsupa base is divided into parts from the base body, there is an advantage that the cost of repair is reduced.

Claims (1)

[Scope of utility model registration request] In the case where the Atsupa base is attached to the base body and the seat body is attached on top of it, a height difference is provided between the base body attachment part of the Atsupa base and the seat body attachment part, so that the Atsupa base can be installed and used by reversing it.
