[0001] The present invention relates to an inner seat for a vehicle, and more particularly, to a safe storage type inner seat assembly for a vehicle that is stored in the floor of the rear of a vehicle, can be pulled out from the trunk of the vehicle when necessary, and can be safely stored without being folded out even when the vehicle vibrates.

[0002] Recently, the trend is to use vehicles not only as a means of transportation, but also for various purposes such as camping and picnics.

[0003] A technology is being introduced that utilizes the rear floor or trunk of a vehicle for various activities, and a technology that utilizes the tailgate of a vehicle is being introduced as a prior art.

[0004] A vehicle's tailgate refers to the rear door of the vehicle. Passengers can open it to store luggage or use it as a passageway for boarding and disembarking. However, the prior art requires a seat to be installed in the vehicle's tailgate, making it difficult to install in existing vehicles that were shipped without a seat installed.

[0005] Additionally, in the case of tailgates that lift up from sedans or SUVs, there was a problem in that it was difficult to install them on the doors of the lifted vehicles, making it difficult to apply them to various types of vehicles.

[0006] In addition, in the case of conventional vehicle inner seats, a separate table must be provided when sitting on the inner seat to eat or read, etc., but it is difficult to provide a table that is suitable for the height of the inner seat, etc., and when the table is installed as an integral part of the inner seat, the folding structure of the table and the inner seat is complicated, making it inconvenient to use the inner seat and table together.

[0007] In addition, conventional inner seats for vehicles are stored by folding them in the trunk of the vehicle, but there are inconveniences such as the inner seat stored in the trunk being unintentionally folded inside the trunk of the vehicle due to vibrations or shocks generated while the vehicle is being driven, causing accidents or damage to items stored in the trunk.

[0008] The present invention is intended to solve the problems of the prior art described above, and an object of the present invention is to provide a safe storage type inner seat assembly for a vehicle that can be safely and simply stored on the floor of the rear of a vehicle, pulled out from the trunk of the vehicle when necessary, and can be safely stored without being folded out even when the vehicle vibrates during storage.

[0009] Another object of the present invention is to provide a vehicle inner seat assembly that can be easily unfolded without difficulty even when manually unfolded when a user wishes to unfold the vehicle inner seat.

[0010] Another object of the present invention is to provide a table assembly that can be easily stored in a vehicle inner seat, and can be easily unfolded and safely locked when in use.

[0011] In order to achieve the above-described object, the present invention provides a safety-storage type inner seat assembly for a vehicle, comprising a seat unit installed on the rear floor of a vehicle, wherein the seat unit comprises a seat portion including a seat back and a seat cushion that are installed so as to be retractable on the rear floor of the vehicle and are relatively rotated and unfolded when retracted, a leg assembly that is hinge-rotatably installed on the bottom surface of the seat cushion, a mounting bracket that is installed on the rear floor of the vehicle and to which the leg assembly is fixed, and a locking bracket that is fastened at one end to the seat cushion and at the other end to the mounting bracket when the seat portion is stored, thereby preventing the seat portion from being unfolded.

[0012] According to the present invention having the above-described configuration, a user can easily withdraw the seat from the trunk of a vehicle when necessary, and the withdrawn seat can be safely fixed by a locking bar. When stored, the seat is prevented from being folded unintentionally and unfolding inside the trunk when vibrations occur in the vehicle, thereby preventing a safety accident from occurring.

[0013] In addition, the present invention can provide a vehicle inner seat assembly that can be easily and effortlessly unfolded even when manually unfolded by a user when manually releasing the folding of the vehicle inner seat to unfold it.

[0014] In addition, the present invention provides a table that is easy to store and use by simply storing the table in the inner seat of a vehicle, and is configured to be easily stored between the seat back and seat cushion of the inner seat of a vehicle after use, thereby providing a table that is easy to store and use.
