The market size for this type of restructuring of campervans is expected to be in the hundreds of billions of won per year in Korea, and in most developed countries including the United States and Germany, it is a trend to change the structure in accordance with the law in that it can solve many job creation with tens of trillions of won. is increasing

Vehicles that can be suitably converted as most campers are a passenger car with three or more rows of seats, vans, and trucks, added to the essential sleeping facilities, and installed in any one of the cooking facilities, washroom facilities, sinks, tables, and toilets. Structural change approval can be obtained when the appropriate facilities are in place.

Here, the camper is a vehicle configured for the purpose of providing a sleeping and cooking space or transporting camping equipment, and since such a camper is movable, it has the advantage of being able to move to a desired place at any time.

On the other hand, the camping box means a facility that is stored in a camper or general vehicle and includes living facilities such as a bed and a sink or accommodates camping equipment therein. can be accommodated and moved.

On the other hand, when a conventional van is converted into a camper, there are cases where a table is provided for various activities such as working on documents indoors, eating snacks, or eating. Most of them are fixed or foldable, so the internal space of the table itself There is a problem that not only the usability, but also the usability and the efficiency according to the use are deteriorated, and in the case of folding, the operability is also deteriorated.

In addition, the vehicle seat forms a seat for maintaining a comfortable riding posture of the occupant. It is provided in the driver's seat and the front passenger's seat and provided at the rear of the driver's seat so that only one person can be seated and a separator type seat that can seat several people at the same time.

In the case of a general passenger car, only the separator-type seat provided in the double driver's seat and the passenger seat is installed on the upper part of the seat rail so that the seat can slide in the front and rear directions. is configured to

In the case of multi-seater vans such as 7-seater, 9-seater, and 12-seater, which are sold a lot recently, the bench-type seat or multi-row seat provided at the rear of the driver's seat is also installed to be slidable in the front and rear directions, so that the seat can be adjusted according to the physical condition of the occupant. It is configured to move in the forward and backward directions.

In the case of modern people who spend a lot of time in the vehicle, they are engaged in various activities such as surfing the web, watching videos, working on documents, or eating snacks or meals using a laptop or mobile device in the vehicle. For this purpose, a table is essential in the vehicle.

However, conventionally, most of the cases use a folding table installed on the rear surface of the front seat for in-vehicle activities. However, the conventional folding table for a vehicle is supported and fixed by a hinge on only one side, so there is a limit to supporting a heavy load. As the position is fixed on the rear surface of the front seat, there is a problem in that it is inconvenient to use the vehicle seat itself to be moved in the front-rear direction for proper use.
