The present invention relates to a wheelchair combined driver seat structure of a vehicle, and more particularly, to enable a person with a disability to independently get on and off the vehicle, and to store and drive a wheelchair without using a third party. It relates to a wheelchair seat structure.

In general, various types of vehicles for the disabled for the physically handicapped are not available and can be broadly classified into the following two types.

A vehicle equipped with a driving assistance device for the handicapped person with a disability in which a specific part of the body is inconvenient by attaching a device capable of operating an Excel and a brake by hand, a lift device that allows the disabled person to ride in a wheelchair while being in a wheelchair, and a seat of the vehicle in a wheelchair. It is equipped with a slide-up seat that can be easily transported into a car, and can be classified as a vehicle for convenient care when a normal person travels with a disabled person.

In these cases, people with disabilities may need a third party to drive a heavy wheelchair in their car or drive a vehicle for spatial movement.

As a result, the right of movement of the disabled is not guaranteed by the current devices. To ensure the right of movement of the disabled, the disabled can move to the vehicle alone and ride in the vehicle without assistance of a third party. The vehicle should be loaded on the vehicle, the vehicle can be driven to the desired destination, and after arriving at the destination, the passenger must get off the vehicle alone and rely on a wheelchair to enable the movement of the local area (for example, banking).

In order to be able to respond to the disabled alone without the help of a third party in all the movement process as described above, the current device is very insufficient situation, and in order to solve the above problems, we devised a device related to the seat that can be used as a wheelchair combined.

Conventionally, parts related to seats of a vehicle for the convenience of the disabled are largely divided into two parts as follows.

First, there is a vehicle structure in which the seat is rotated and pushed out of the vehicle so as to be easily moved from the wheelchair to the seat, and second, a vehicle structure equipped with a wheelchair lift for moving the passenger inside the vehicle while sitting in the wheelchair.

However, in the former case, when the seat is installed in the driver's seat, the rotation is limited due to interference with the steering wheel, and it cannot be pushed out. Therefore, the seat should generally be installed in the passenger seat or the rear seat. In this case, there is a problem in that it is impossible for the disabled to move independently because a person who needs to put a wheelchair on a vehicle or a person who drives the vehicle is required.

In the latter case, a person with a disability can operate a lift device by himself, but can ride in a vehicle, but needs a person to drive the vehicle.

In addition, since the wheelchair is lifted from the bottom of the wheelchair wheel, a wider lift device than the wheelchair is required, so that the door can be accessed only by a wide tail gate.

Therefore, it is possible to apply only to the vehicle having the tail gate, and there is an inconvenience in that all of the two rows and three rows of seats need to be removed to provide a riding space of the wheelchair.

In addition, there is a disadvantage that the indoor height should be high enough because the disabled ride in the car while in a wheelchair.

Therefore, the conventional method has a problem that it is impossible for a disabled person to completely get on and off a vehicle and drive or to receive and move a wheelchair.

Therefore, the present invention has been invented to solve the above problems, equipped with a foldable wheel to be able to change the use of the wheelchair to the bottom of the driver's seat, the combination of the lift device on the lower end of the cushion portion The driver's seat is provided with a docking part having a guide part, which is capable of forming a coupling hook at the distal end of the wheel frame of the wheel, and at the same time, installing a seat locking device to secure the seat to the body floor by fixing the coupling hook in the body floor. By installing a lift device in such a way that the seat can be accessed through the side door and move to the driver's seat, the disabled person can move to the vehicle independently without the help of a third party, and then get on and off the vehicle, store the wheelchair, and drive the car. Wheelchair combined use driving of car which can completely secure the right of movement of person with a disability It is an object of the invention to provide a stone sheet structure.

Hereinafter, the features of the present invention for achieving the above object are as follows.
