The wire body 1 is composed of a plurality of bending parts 2 and strip parts 3, and the plurality of bending parts 2 and strip parts 3 are connected end to end. The arrangement of the bending parts 2 and strip parts 3 enables the wire body 1 to be laid in a serpentine structure, so as to increase the laying range of the wire body 1 in the automotive seat, thereby achieving the purpose of improving the heating effect of the wire body 1.

[0022] Specifically, the wire body 1 includes a support rib 4, a heating wire 5, a heat conduction sleeve 6, and a braided outer sleeve 7. The support rib 4, heating wire 5, heat conduction sleeve 6, and braided outer sleeve 7 are arranged in sequence from the inside out. The support rib 4 is arranged in a "cross" shape, and a support sleeve 41 is arranged in the middle of the support rib 4. The support sleeve 41 is arranged in a circular structure. Four first cavities 42 are arranged inside the support rib 4, and the four first cavities 42 are respectively arranged inside the four sides of the support rib 4. A second cavity 43 is arranged inside the support sleeve 41, and the second cavity 43 is arranged in a circular structure. The arrangement of the first cavity 42 and the second cavity 43 enables the support rib 4 and the support sleeve 41 to deform, thus facilitating the laying of the wire body 1.

[0023] More specifically, there are four heating wires 5, and the four heating wires 5 are arranged around the outside of the support rib 4. An insulating sleeve 51 is arranged outside the heating wire 5, and the insulating sleeve 51 is arranged as an aluminum oxide heat-conducting rubber sleeve. A plurality of heat conduction pads 61 are fixedly arranged on the outer side wall of the heat conduction sleeve 6. The heat conduction pads 61 are arranged in an isosceles trapezoid structure, and adjacent two heat conduction pads 61 are arranged in a staggered manner. The heat conduction pads 61 are made of heat-conducting silica gel, and the heat-conducting silica gel can achieve the dispersed transmission of heat to ensure the uniform divergence of the heat generated by the heating wire 5. The braided outer sleeve 7 is arranged as a nylon braided layer, and the nylon braided layer can improve the wear resistance of the wire body 1 while ensuring the heat dissipation of the heat conduction pads 61, so as to ensure the stability of the wire body 1 during long-term use.

[0024] In the present utility model, a support rib 4 and a heating wire 5 are arranged inside a wire body 1. The support rib 4 is arranged in a "cross" shape structure, and the heating wire 5 is wound around the outside of the support rib 4. The support rib 4 can limit the four heating wires 5 through its "cross" shaped structure to ensure that the four heating wires 5 do not interfere with each other when the wire body 1 is bent and deformed, so that the situation of winding and twisting of the heating wire 5 will not occur, thereby ensuring the stability of the heating wire 5 during the application process of the wire body 1. By arranging a heat conducting sleeve 6 outside the heating wire 5, the heat conducting sleeve 6 cooperates with the support rib 4, which can play a role in limiting the heating wire 5. Moreover, a heat conducting pad 61 is arranged on the outside of the heat conducting sleeve 6. The heat conducting pad 61 is made of heat conducting silica gel. The heat conducting pad 61 can play a role in dispersing and transmitting the heat emitted by the heating wire 5 to ensure the uniform heating of the wire body 1, thereby ensuring the use effect of the wire body 1.
