Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a seat incorporating a heater unit.

[Prior art]

As shown in FIG. 5, a seat 2 incorporating a heater unit A (FIG. 6) having a planar heating element 1 is known in order to keep the seated person warm. , are arranged on the side of the surface layer material 4 containing the wading 4, and are located above or above the cushioning material 6. The planar heating element 1 includes a plate-like base 7 without a heat-generating element, and a plurality of strips 8a, 8b, . It consists of thermostats 9, 9 attached to a plate-like base 7.

The plurality of strips 8a, 8b, . . . may shift in the left-right direction of the seat due to the movement of the seated person and overlap each other, resulting in a drawback that uniform heating cannot be achieved. In order to prevent the above-mentioned slippage, there is a method in which the strips 8a, 8b, . . . are clipped one by one to the surface material, but this has the disadvantage of poor workability.

[Summary of the idea]

This idea involves folding the tip of each strip so as to surround the wire, connecting the tip to the main body of the strip, and connecting the wire to a frame that holds the cushioning material or to a fixing member embedded in the cushioning material. A structure in which a friction member is interposed between the wire rod and the folded portion of the strip portion so as to surround the wire rod and fill the space between the wire rod and the folded portion of the strip portion, while holding each of the folded portions. By doing so, the above-mentioned drawbacks are eliminated.

This invention will be explained in detail below using examples.

[Example of idea]

Fig. 1 is a perspective view of a heater unit applied to an embodiment of this invention, Fig. 2 is an enlarged side view of the folded portion of the strip portion shown in Fig. 1, and Fig. 3 is a holding structure for the folded portion of the strip portion. FIG.

As shown in FIGS. 1 and 2, the tips of the strips 11a, 11b, . Tip 13

Friction members 16a, 16b, . . . are interposed so as to fill the spaces between them. Then, this heater unit B is placed on the cushioning material 17, and the strip portions 11a, 11 of the planar heating element C of the heater unit are placed.
The tip folded portions 15a, 15b... of b,..., respectively
The wire rod 12 surrounded by the friction members 16a, 16b, etc. is inserted into the groove 18 provided in the cushioning material 17, as shown in FIG. They are connected by clips 20, and the folded portions of the respective strips are held, in other words, the edge of the sheet heating element on the side where the heating element is located.

As shown in FIG. 4, the wire rod 12 may be connected to a frame 21 that holds a buffer body to hold the edge of the planar heating element, or the wire rod 12 and the fixing member 19 or the frame 21 may be connected using an extension of the wire itself without using the ohm clip 20.

In both the embodiments shown in FIGS. 3 and 4, the strips did not overlap.

[Effect of the device] This device folds the tip of each strip so as to surround the wire, connects the tip to the main body side of the strip, and embeds the wire in a frame that holds the cushioning material or in the cushioning material. It is connected to a fixing member to hold each of the above-mentioned folded parts, and a friction member is provided between the folded part of the strip of the wire so as to surround the wire and fill the gap between the wire and the folded part of the strip. Because the member is interposed, the position of the wire is fixed with a simple structure, and there is no misalignment between the folded part of the strip and the wire, so the strips do not overlap and maintain a uniform heating state. Make the most of your efforts.
