Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile seat in which cold or heated air from an air conditioner is supplied to a seat cushion or a seat bag to cool or heat a seated person in a contact manner.

It is faster to cool or heat the interior of a car by directing cold or warm air to the occupants from the seat, rather than by sending cold or warm air into the car to cool or warm the atmosphere inside the car. In recent years, seats have been developed that cool or heat the occupant in contact with the seat by sending cool air or heating to the seat cushion or seat back because of its high heating rate, low energy loss, and low power loss. There is.

Such a cooling or heating seat has a plurality of ventilation holes opened on the top surface of the padding material of the seat cushion and the front surface of the padding material of the seat back.
An air chamber is formed at the rear of this ventilation hole, and a duct from the air conditioner is connected to this air chamber, and after the cold or warm air supplied from the air conditioner is stored in the air chamber, the air chamber is connected to the air chamber. It is ejected from the pores. Conventionally, the air chambers of such seats were formed by attaching a box to the seat padding material, which affected the amount of flexing of the padding material when the passenger was seated, resulting in poor cushioning properties. Not only did it damage the product, but it also fell off even after it was installed, causing accidents. Furthermore, the installation of the box body was troublesome, resulting in low productivity and a rise in prices.

This invention takes advantage of the fact that the seat pad material can be integrally molded by synthetic resin foaming, and when foaming, a recess is simultaneously molded at the rear of the ventilation hole, and the lid is attached to the recess. The above drawbacks are solved by eliminating the need for a box and forming an air chamber without impairing the cushioning properties of the seat.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

1 and 2 are cross-sectional views of a synthetic resin foaming mold, and FIGS. 3 to 5 are views showing an example of a molded seat bag.

Synthetic resin foam molding is performed by foaming a foamable synthetic resin such as polyurethane resin or polystyrene resin in a predetermined mold, and the mold used generally consists of an upper mold 1 and a lower mold 2. Ori,
A sheet-shaped cavity 3 is formed inside. In this foam molding, the frame 4 of the sheet and insert members such as S springs 15 that are stretched over the frame 4 to provide elasticity are positioned in advance in the mold, and the synthetic resin is foamed at the same time. These insert members 4 and 5 are embedded in the pad material and integrally molded. The lower mold 2 of such a foaming mold has a plurality of bosses 6, 6.
... protrudes upward, and the upper mold 1 has boss holes 7, 7, which have a slightly larger diameter than the bosses 6, 6...
is opened. When the upper mold 1 and the lower mold are fitted and synthetic resin foaming is performed, the bosses 6, 6, . . .
2... is starting to be formed. in this case,
The gap between the boss hole and the boss is used for degassing, and during degassing, an amorphous overflow lump as shown in FIG. 2 is formed, but this lump is scraped off in a later process. Further, the central portion of the lower die 2 is raised to form a convex portion 8. This convex part 8 is formed on the lower mold 2 in order to form the concave part 13 shown in FIG. 13 is being formed.

As shown in FIG. 3, the seat bag 11 foam-molded as described above includes a frame 4 and an S spring 5 embedded in a sheet-shaped pad 14, and a plurality of ventilation holes 1 in the pad material 14.
2, 12... have been opened. A box-shaped recess 13 is provided at the rear of the ventilation holes 12, 12...
is formed, and a lid 15 as shown in FIG. 4 is attached to this recess 13. A bellows-shaped duct 16 connected to an air conditioner (not shown) is attached to the lid 15, and a sealing material or the like is placed around the lid 15 to maintain airtightness when it is attached to the recess 13. However, after the lid body 15 is attached in this way,
As shown in FIG. 5, an air chamber 17 is formed at the rear of the ventilation holes 12, 12.... Therefore, when cold air or warm air is supplied from the air conditioner, this cold air or warm air is stored in the air chamber 17 and the air vent 1
2, 12, etc., and contact cooling or heating of the seated person is performed.

Seat bag 11 formed as above
Since the air chamber is not made of a box but is made of pad material, the cushioning properties when sitting are not deteriorated, and it is easy to assemble and is inexpensive.

Note that the above configuration is formed not only in the seat bag 11 but also in the seat cushion 21,
Thereby, cooling or heating can be performed from both the seat cushion 21 and the seat bag 11.

6 and 7 show another embodiment of the present invention, the same parts as in the previous embodiment are given the same reference numerals, and the details are omitted, but in this embodiment, the pad A groove 18 is formed in the lower part of the recess 13 of the material 14. This groove 18 is integrally molded during foam molding by forming appropriate protrusions on the lower mold, and the duct 16 of the air conditioner is fitted into this groove 18. . Therefore, the lid 15 attached to the recess 13
There is no need to attach a duct to the system, which improves ease of handling during assembly. This groove 18 may be formed on the side of the recessed portion as shown in FIG. 7, and in any case, cold or warm air from the air conditioner can be well supplied into the air chamber.

As explained above, according to the present invention, the recesses are integrally molded together with the ventilation holes during synthetic resin foaming,
Since the air chamber is formed by attaching the lid to this concave portion, the cushioning properties of the seat are improved, assembly is easy, and failures such as falling off do not occur.
