As shown in fig. 2, the movable rail 22 is coupled to the coupling hole 1621 of the boss 162 by the second bolt 24. As shown in fig. 4, the movable ends 11b of the two loading portions 111 are respectively clamped to the two buckles 1611 of the seat portion 161, and two wire harnesses installed in the two loading portions 111 penetrate through the wire harness through hole 1622 after penetrating out from the port of the movable end 11b of the loading portion 111, and are mixed into one wire harness through hole 1622.

As shown in fig. 4, the restoring member 13 is connected to the sliding guide 12 for providing restoring force to the sliding guide 12. In the figure, the reset part 13 includes two reset parts 131, and the reset parts 131 are springs, but other elastic parts or power-type driving parts with larger elasticity may be adopted. As shown in fig. 6, two connecting portions 123 are disposed on two sides of the guiding surface of the sliding guide 12, two hooks 1231 are disposed on the two connecting portions 123, one end of each of the two springs is connected to the hooks 1231 of the two connecting portions 123, and the other end of each of the two springs is connected to the hook on the housing 14. Both springs are parallel to the sliding direction of the sliding guide 12. In actual practice, only one reset unit 131 may be provided. However, comparatively speaking, set up two portions of reseing 131 and let two portions of reseing 131 even in the spigot surface both sides of sliding guide 12, like this, more can ensure the stability of the power that resets, can prevent that the sliding guide 12 from resetting the in-process because of the uneven skew problem that leads to the jamming of atress to can further promote receipts line smoothness nature.

The following explains the wire-out action and the wire-in action by taking the view angle of fig. 4 as an example:

when the movable rail 22 slides backward, the pulling member 16 is moved backward, and at this time, the movable end 11b of the loading portion 111 moves backward, and the wire harness 300 moves backward together with the loading portion 111, thereby protruding from the housing 14 to be wired. In the wire feeding process, the slide guide 12 moves forward by the pulling action of the loading portion 111, and the reset portion 131 is elongated (the state shown in fig. 7);

when the movable rail 22 slides forward, the traction member 16 is driven to move forward to abut against the traction member 16, so that the movable end 11b of the loading portion 111 is pressed forward, meanwhile, the elastic force of the reset portion 131 acts on the sliding guide 12, so that the sliding guide 12 is pressed backward, the loading portion 111 attached to the sliding guide 12 is also pressed backward, at this time, the loading portion 111 is reset to the inside of the housing 14 under the action of the pressing force and the elastic force, and the wire harness is retracted into the housing 14 along with the loading portion 111 to realize wire winding. During the wire rewinding process, the reset portion 131 gradually returns to the natural state (the state shown in fig. 8) from the elongated state.

In addition, the invention also provides a seat system, which comprises the wiring device 100, a seat and a sliding rail pair 200. The seat is connected to the movable rail 22 of the slide rail pair 200, and the retractor 16 of the wiring device 100 is also connected to the movable rail 22 of the slide rail pair 200.

The above description of the embodiments is only intended to facilitate the understanding of the method of the invention and its core idea. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the principles of the invention, and it is intended that such changes and modifications also fall within the scope of the appended claims.
