Abstract

PURPOSE:To reduce assembling processes for the title seat and the number of parts therefor, by a method wherein both a pad support for a pad with air-permeability and having a number of ventilation holes on the side of the pad which communicate with hollow ventilating-pathways, and a means for blowing the air into the ventilating-pathways are provided. CONSTITUTION:When a ventilating fan 11 is driven, the air entering a largish ventilation opening 10 in a pad support 3 is led into each of ventlating-pathways 7 out of a cavity part 9 and enters the inside of a pad 2 with air-permeability through ventilation holes 8. After that, the air is passed through a surface skin 1 and exhausted outward, and thus a person seated is notmosity. Since a plurality of the hollow ventilation holes 7 branching are simultaneously molded when the pad support 3 is molded, it is not necessary to form an air chamber independently, and sealing for making airtight each part in the air chamber is also made unnecessary. Therefore, the assembling processes for the title seat and the number of parts therefor can be reduced and the design therefor is made easy. In addition, working efficiency for assembling is improved and the space therefor can be made small.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ventilation structure for an automobile seat, which supplies air to a seat cushion and a seat back to eliminate the stuffiness of a seated person.

[Prior Art] Conventional ventilation structures for automobile seats include opening vent holes in the seat cushion and seat back pad, forming an air chamber at the rear of the vent hole, and supplying air from a near conditioner to this air chamber. It is known that a duct is connected to the air chamber so that cold or warm air supplied to the air chamber is blown out from the air hole.

[Problems to be Solved by the Invention] However, in the conventional car seat ventilation structure described above, the air chamber is provided by using separate parts, and each part of this air chamber is sealed to improve the sealing performance. There are problems in that it has to be shaped like a balloon, requires many steps to assemble, and has a large number of parts, making it difficult to design, as well as requiring space.

The present invention has been made in view of the above-mentioned circumstances, and is intended to simplify the design by reducing assembly processes and the number of parts, as well as to reduce the space required for ventilation of automobile seats. The purpose is to provide structure.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pad having breathability, a hollow air passage that supports the pad, and a large number of air holes on the side of the pad that communicate with the air passage. The present invention is characterized by comprising a pad support having a pad support, and an air blowing means for blowing air into the ventilation passage of the pad support.

C effect The hollow air passage of the copad support can be molded at the same time as the pad support is molded, and since the air blowing means is attached to this air passage, the conventional air chamber is no longer necessary, and the assembly process can be reduced. This makes it possible to reduce the number of parts and the number of parts, and also requires less space.

[Embodiment] Hereinafter, embodiments of the present invention will be described based on FIGS. 1 to 11.

1 to 3 show cross-sectional views of three types of seat cushions before installation of air blowing means.

In FIGS. 1 to 3, a breathable pad 2 coated on the skin 1 is supported by a pad support 3, 64 is a spring, and 5 is a frame. In FIG. 3, a breathable pad 2 is used for the main part, and a normal pad 6 is used for the bank part.

The pad support 3 is made of a synthetic resin having surface rigidity, and is molded, for example, by blow molding, and has a hollow portion branched into a plurality of parts, and this hollow portion serves as a ventilation path 7. A large number of ventilation holes 8 are provided on the front side (pad side) of the ventilation passage 7, and one part of the ventilation passage 7 is formed in a large hollow part 9, and the back side (reverse side) of this large hollow part 9 is formed in one place. On the pad side), a large ventilation hole 10 is provided for attaching an air blowing means to be described later.

The ventilation fan 11 as an air blowing means has the same fan diameter as the larger ventilation hole 10 described above, and as shown in FIG. It is attached to the pad support 3 from the back side (the side opposite to the pad) of the pad support 3 so as to cover the ventilation hole 1o.

Here, instead of the ventilation fan 11 as an air blowing means, an air hose 14 that guides air from a near conditioner (not shown) of the automobile is used as an air blowing means, as shown in FIG. It may be connected to the air hose mounting bracket 16 installed so as to cover the circle.

FIGS. 9 to 11 show cases in which ventilation fans 11 are attached to the three types of seat cushions shown in FIGS. 1 to 3, respectively. In this case, the ventilation fan 11
When turned, as shown by the arrow, air enters from the large ventilation hole 1o, passes through each ventilation path 7 from the large hollow part 9, exits from the ventilation hole 8, enters the breathable pad 2, and enters the epidermis 1.
It goes further outside and eliminates the feeling of stuffiness in the seated person.

In this embodiment, since the plurality of branched hollow air passages 7 of the pad support 3 are molded at the same time as the pad support 3 is molded, the conventional air chamber is not required. In other words, since there is no need for seals to improve the sealing performance of each part of the air chamber, assembly processes can be reduced and the number of parts can be reduced, making design easier and assembly easier. Also, it takes up less space.

[Effects of the Invention] As described above, according to the present invention, a pad support having a hollow ventilation passage and a large number of ventilation holes on the pad side communicating with the ventilation passage is provided, and the ventilation of the pad support is Since air is blown into the channel using an air blowing means, the conventional air chamber is no longer necessary, making it possible to reduce assembly steps and the number of parts, making the design easier and the assembly easier. will improve. Moreover, the space can be reduced.
