The slide rail system can be independently constructed, so that the universality of the device is improved, and the slide rail system can also be used in vehicles with different slide rails, thereby enlarging the yield and reducing the cost. However, the triangular shell with the sliding groove for supporting the wire harness is added, the wire harness lead sliding block is pushed by the movement of the seat, and the redundant wire harness is collected in the triangular shell, so that the mechanism is suitable for the seat with the sliding rail formed as 600mm and cannot be applied to the seat formed in a larger size.

5. The harness routing device for the slide seat disclosed in chinese patent CN105793114B is configured such that a harness storage box is added below the seat rail, and a track-type package is adopted, and such a mechanism requires a space of a certain depth to be added below the seat rail, and thus the practical feasibility is not high.

6. The harness routing device disclosed in chinese patent CN102574490B utilizes a long cylindrical rail fixed on a vehicle body and a slider therein to route a harness, is provided with a surplus length accommodating portion for accommodating a surplus length portion of the harness pulled out of the rail in a U-shaped bent state, and moves forward and backward through the slider.

7. The harness routing device disclosed in chinese patent CN102625752B is a mechanism in which a seat is required to have a cylindrical metal rail for accommodating a harness, and a receiving member adjacent to the harness of the remaining length, and a harness slider is disposed in the metal rail for guiding the harness.

8. The sliding seat power supply device disclosed in chinese patent CN1810544A is configured such that a wire harness storage box is added below the seat, and extra wire harnesses are stored in the storage box, and a track-type package is adopted, and such a mechanism requires a space of a certain depth added below the seat rail, and thus the practical feasibility is not high.

9. According to the Toyota ALPHA slide rail wiring mode, a seat guide rail is additionally provided with a wire harness guide rail, a wire harness lead slider moves in a guide rail sliding groove, and a wire harness is contained in the guide rail.

10. The sliding wiring device disclosed in chinese patent CN108475910A adopts a track-type structure, the slide rail pushes the lead to move in the slide rail groove, the redundant wiring harness is accommodated in the accommodating portion, the wiring harness moves in the slide rail groove along the outside, and there is a distortion risk in the blocked condition.

None of the above patents mention the use of flat cables in the wiring harness. Due to the increase in the seat function configuration, the number of wires required to pass through the harness box increases. The current wire harness box is limited in the number of wires which can pass through the wire harness box due to the space of an inner cavity of a sliding rail and the structure of the wires (large occupied space). In addition, the durability of the seat is required to be higher in the market at present, and the durability of the current conducting wire cannot meet the requirement. The existing wire is required to have a large turning radius, so that the width of the wire harness box is wide, the wire harness box occupies a large space at the lower part of the seat, and the cost is high.
