Description

Folding instructional seat for an agricultural work vehicle}

The present invention relates to a folding chair for training in an agricultural work vehicle. More specifically, it is disposed on the side of the driver's seat to provide an auxiliary seating surface on which a person other than the driver can sit, and can be folded so as not to be in the way when the driver gets on or off the vehicle. This relates to a folding chair for educational use on agricultural work vehicles.

Agricultural work vehicles, well known as 'tractors', are structurally similar to ordinary cars, but are equipped with powerful engines and large wheels, so they have good traction and are advantageous for wet field work, so they are mainly used for farming. In a typical tractor, the driver's seat is located between the front wheel, which is the steering wheel, and the rear wheel, which is larger than the front wheel, and the driving unit is located in front of the driver's seat.

The driver's seat varies depending on the vehicle's specifications, but basically, a steering handle is placed in front of the driver's seat where the driver is located, and various operating levers and switches with different functions are located around the steering wheel and on the left and right sides of the driver's seat. there is. In order to provide a comfortable and safe driving environment, the structure (cabin type) where a box-shaped cabin made of transparent glass protects the driver's seat is also well known.

The driver's seat of a tractor generally consists of a single seat. Therefore, there is no suitable space for anyone other than the driver. In particular, in the case of the cabin type, space is limited, so it is more difficult for a passenger to join. However, there are times when it is necessary to have someone other than the driver ride with you, such as operating a device or driving training.

However, as explained earlier, conventional conventional tractors do not have adequate space or seating for a passenger, so when someone other than the driver rides, the passenger is crouched in an uncomfortable position that does not interfere with driving, or falls on the side of the driver's seat. There are problems with riding together, such as having to stand in a dangerous position, and being exposed to the risk of safety accidents.
