Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle seat that heats the vehicle by being attached to the seat of a vehicle or the like.

Prior Art FIG. 4 is a perspective view showing a vehicle seat 23 equipped with a heater unit, in which 12 is a seat part, 13 is a back part between the front/fi 14.15 of the seat 23 and the main pad 16.17, respectively. A heater unit 18,19 is installed.

The plan view in FIG. 5(,) and the cross-sectional view in FIG.
is a flexible support such as a heavy body, and a heating element 21 is disposed between the two layers. 22 is a lead wire, and 31 is a connector for connecting to a vehicle power source or the like (not shown).

Moreover, this heater unit 1B has notches 32a, 32.
b and a punch-out hole 33 are provided for pushing through a hanging cloth for suspending and locking the skin 14, which will be described later.

FIG. 6 shows how the heater unit 18 is connected to the seat 12 of the seat 23.
FIG. 7 shows an enlarged cross-sectional view of the locking portion shown in FIG.

In FIG. 7, both ends of the heater unit 18 are connected to the seat portions 12.
The outer skin 14, a urethane layer 24 with a thickness of about 10 mm, and a hanging cloth 29 are sewn at the same time 30, and a hanging wire 28 for locking is pushed through the hanging cloth 29, and this hanging wire 2B
is the connection I! buried in the hanging groove 25 of the main pad 16! r
, is secured to the metal fitting 27 with a clip 26.

3 - FIG. 8 is a perspective view showing the seat portion 12 of the seat 23. Generally, from the design point of view, the outer skin 14 is suspended from the main pad 16 to form four portions 34.

FIG. 9(a) is a perspective view showing the suspended part of the skin 14 in FIG. 8 and the heater unit installed on one day;
) is a cross-sectional view of a hanging part forming the four parts 34.

In FIG. 9, the outer skin 14 is attached to the main pad 16 using the hanging cloth 29, the hanging wire 28, and the crimp 26 in order to form the four parts 34, but in this case, it is necessary to push the heater unit 18 through. Because there is a hanging cloth 2
(In addition to providing notches 35a and 35b in 9, the heater unit 18 is provided with similar notches 32a and 35b, as shown in FIG.
32b and a hole 33 were provided. Other methods include securing the length required for hanging the hanging portion of the skin 14 in advance, and connecting the heater unit with an insertion hole for the clip 26 or connecting divided heater units with lead wires. there were.

Problems to be Solved by the Invention The configuration of such a conventional heater unit has the following problems.

(1) It is necessary to fix the heater unit 18 to the skin 14 in advance, and for this purpose, the heater unit 18 is sewn to the skin 14 together with the hanging cloth 29, which requires time and effort for positioning and poor workability.

(2) There is a risk of damaging the heating element 21 provided in the heater unit 18 during sewing.

(3) Since the heater unit 18 is kneaded on the front surface i14 and both ends, tensile force is applied to the heater unit 18 due to the bending of the seat surface when seated, resulting in deterioration of cushioning properties due to a stiff feeling when seated. , there is a risk that the heating element 21 may be disconnected.

On the other hand, if the skin 14 is sewn with a margin in the heater unit 18, wrinkles will occur in the heater unit 18, resulting in abnormal overheating and breakage of the heating element due to repeated bending.

(4) In order to insert the heater unit 1, cutouts 35a and 35b are required in the hanging cloth 29.
-7. As a result, the suspension force near the notches 35a and 35b becomes weak, and the formation of the recesses 34 in the skin 14 becomes uneven, resulting in problems in terms of design.

Unfortunately, the heater unit 18 also has a notch 32a.

32b and punch holes 33 are required, and the strength is significantly impaired.

(5) If a problem occurs in the market, replacing only the heater unit 18 requires sewing it with the skin 14, which essentially requires a special sewing machine, so it is customary to replace the entire seat or skin. It has become.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a vehicle seat that prevents danger and improves workability and serviceability.

Means for Solving the Problems In order to solve the above problems, the present invention consists of a plurality of heater units, a lead wire having a detachable connector extends from each heater unit, and a skin body. +h
This is a hanging cloth with a slit in the hanging direction.

6/.Function The present invention, with the above-described configuration, eliminates the need to sew the heater unit and the outer skin, and further eliminates the need for a cutout in the hanging cloth, a cutout in the heater unit, and a punch hole.
It is possible to eliminate the risk of malfunctions and improve workability and serviceability.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIG. 1 (a), 1a and Ib are heater units, and the heater unit 1a includes a vehicle power supply (not shown).
A lead wire 3 having a connector 5 connected to the heater unit 1b, and a lead wire 4 having a connector 6a connected to the heater unit 1b.
a is extended. On the other hand, a lead wire 4b having a connector 6b connected to the heater unit 1a extends from the heater unit 1b. Here, the lead wires 4a and 4b extend in opposite directions, and the connectors 6a and 6b are in a male and female relationship with each other and can be freely attached and detached.

7., -1. Note that the lead wires 4a and 4b extend from the heater unit 1a,
It is not limited to the center position of 1b, but may be in the directions facing each other.

FIG. 1(b) is a cross-sectional view of heater units) Ia and 1b.
Heat generating elements 2a and 2b are arranged between layers of flexible supports 7a and 7b, such as heavy bodies.

FIG. 2(a) shows the heater unit +-ia of the present invention.

2(b) is a perspective view showing a state in which the seat 1b is mounted between the seat skin 14 and the main pad 16, and FIG. 2(b) is a sectional view thereof.

In FIG. 2, it is possible to attach the heater unit on the surface of the main pad 160 in advance using tape, etc.), and the hanging cloth 29 for covering the skin, sewn to the skin 14, is buried in the main rose F16 using clips 26. It is fixed to the metal fitting 27 for the retainer 14.

After that, the lead wire 4 of the heat unit) 1a or 1b
a or 4b is inserted through the slit 8 provided in the hanging cloth 29, and electrically connected by the connectors 6a and 6b.

Here, the slit 8 provided in the hanging cloth 29 is as shown in FIG.
), or round holes as shown in Fig. 3(b), or the lead wires 4a, 4 of the heater unit throats Ia, 1b.
However, from the viewpoint of forming a recess 34 in the outer fabric 14 with the hanging cloth 29, it is preferable to provide the slit 8 in the hanging direction of the hanging cloth 29. Most effective. Furthermore, the position of the slit 8 provided in the hanging cloth 29 is not limited to approximately the center, but the optimum position may be determined based on the position of the clip 26, workability, etc.

Note that although the above embodiment shows an example in which two heater units are used, this does not mean that two or more heater units may be used.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) By simply providing a slit in the hanging cloth, there is no need for a notch in the hanging cloth, and the hanging of the skin becomes uniform, thereby solving the problem of forming the skin in four parts.

(2) Since the heater unit can be separated and removably connected using lead wires and connectors through the slits in the hanging cloth, there is no need for cutouts in the heater unit, and the strength can be greatly improved.

(3) Since the heater unit can be placed in advance on the main pad, there is no need for sewing, which improves workability and serviceability, and also prevents problems caused by a feeling of stiffness and wrinkles when seated.
