It relates to a long slide rail system for a vehicle seat in which a cable is inserted and installed in a lower rail installed on a floor panel, so that power and a novel signal can be smoothly supplied to the seat electric equipment without a short circuit of the cable.

In general, a seat of a vehicle includes a seat back and a seat cushion, and a seat slide device is installed to slide the seat cushion in the front and rear direction of the vehicle body, and the slide device is provided with a short slide device like the front seat and is relatively small. It was configured to provide a forward and backward movement distance, but a long slide device is installed in RV vehicles and vans that have a long follower panel because their body is relatively larger than that of a passenger car. It provides a comfortable indoor living space.

The slide device may be classified into a manual type or an electric seat slide according to an operation method. In order to increase user convenience, an electric seat slide is widely used.

In the electric seat slide, the upper rail fixed to the vehicle seat is moved along the lower rail fixed to the vehicle floor by a driving motor, a gearbox (reducer), and a lead screw, so that the seat moves in the front-rear direction. it is made to be

In addition, in recent years, due to the user's demand for increased convenience, the electric vehicle is rapidly progressing, and various convenience specifications for riding comfort and driving convenience are greatly increased in the driver's seat and front passenger's seat.

In particular, a highly complex technology for providing various conveniences for the driver's seat and front passenger's seat is an example of a slide function that slides the seat back and forth, a seat height adjustment function to secure a front view, ventilation and heating (heater) supply function for comfortable driving , a reclining function to adjust the angle of the seatback, etc. are installed, as well as various convenience facilities such as a monitor and air-conditioning control switch on the back of the seatback for the occupants of the rear seat.

In this way, electric sliding, electric reclining, seat heating (heater), operation of a blower for ventilation, etc. are installed on the seat of the vehicle, and various cables for supplying power and signals to these electric equipment are installed, and these electric equipment Various cables for controlling the power supply and signal to the vehicle body are connected and installed so as to be located on one side of the lower rail or in the lower rail to be connected and installed from the power supply (battery, etc.) installed on the floor of the vehicle body to the seat.

However, various cables installed in the prior art are individually connected and installed in accordance with various electrical equipment, and when the upper rail moves in the front and rear directions along the lower rail, interference and kinking between the cables occur, so that the power and signal are adequate. There is a phenomenon that it cannot be supplied and delivered properly.

In particular, in the case of an electric slide, lead screws and gearboxes are installed in the lower rail, so that most cables are installed outside the rail and follow the upper rail moving along the lower rail. With this extra length, the wiring of the cable becomes more complicated, and when the front and rear slides of the sheet, the cable is exposed to the outside and spoils the aesthetics, and the externally exposed cable is damaged or cut, and not only the electrical equipment but also the electrical equipment. , there were various problems such as the operation of the sheet itself was not made.
