The air distributor 12 is used to direct the air flow generated by the air mover 11 to a corresponding seat surface (not shown). do.

A person skilled in the art can understand that the air flow generated by the air mover 11 can blow air directly to the seat surface (ie, blow type) and also suck air (ie, suction type) from the seat surface. And all of this achieves the purpose of seat ventilation by making it possible to generate an air flow corresponding to the surface of the seat.

According to one exemplary embodiment of the present invention, the air distributor 12 may form a structure including a ventilation air bag 121 .

Hereinafter, for easier understanding, the ventilation air bag 121 is described as an example of a blowing type. 2 is an explanatory diagram of the connection between the ventilation air bag 121 and the air mover 11 according to an exemplary embodiment of the present invention.

As shown in FIG. 2 , the ventilation air bag 121 may include a wall 122 and an air inlet 123 formed in the wall 122 and at least one air outlet 124 , the air inlet 123 being Used for fluid communication with the corresponding terminal (here, the vent) of the air mover 11, it receives the air blown by the air mover 11, and the air outlet 124 is an air guiding passage (not shown) in the corresponding portion of the seat. It is used for fluid flow with the city), for example with an air hole in the seat cushion, and guides air to the seat surface and blows it out from the seat surface.

In order to supply and transport air to the seat surface as uniformly as possible, as shown in FIG. 2 , the at least one air outlet 124 includes a plurality of air outlets 124 that are generally distributed. However, those skilled in the art should understand that the quantity and distribution of the air outlets 124 may be different depending on a specific design, and the present invention is not limited thereto.

In addition, as can be seen from FIG. 2 , the air inlet 123 is installed on one side of the ventilation air bag 121 , and the air outlet 124 is installed on the other side of the ventilation air bag 121 .

According to one exemplary embodiment of the present invention, the wall 122 of the ventilation air bag 121 may be formed of or comprise a membrane, in particular an oil-based membrane, such as a polyurethane membrane. Preferably, the ventilation air bag 121 can be formed by welding two membranes through the edge, that is, the two membranes are welded into one at the edge weld 125 , and one membrane is formed at the air inlet 123 . and another membrane is formed at the air outlet 124 . This forming method is simple and inexpensive.

The membrane may have a two-layer structure so that the edges of the membrane can be better welded together, one layer being a polyurethane membrane and the other layer being a cotton flannel, in particular a non-woven fabric.

According to one exemplary embodiment of the present invention, the air distributor 12 may include an air spacer 126 (a vent packing) positioned within a ventilated air bag 121 , the air spacer 126 having a 2 is shown only schematically.

For easier understanding, FIG. 2 schematically illustrates the flow path of air through several arrows 2 . However, those skilled in the art should understand that the actual route may be different from this.

According to one exemplary embodiment of the present invention, the first connection structure 3 may include a connection pedestal 31 and a first connection member 32 . As shown in FIG. 2 , preferably, the connecting pedestal 31 is installed inside the ventilation air bag 121 and surrounds the air inlet 123 and is disposed on the wall 122 . The connecting pedestal 31 is provided with an air passage 311 that is connected with the air inlet 123 and is particularly aligned so that air enters the ventilation air bag 121 from the air mover 11 . In the connected state, the first connecting member 32 is connected to the connecting pedestal 31 and the corresponding part of the air mover 11 (eg, the connecting protrusion 111 of the housing) as one, and surrounds the air inlet of the ventilation air bag 121 . The wall part 127 of 123 is sandwiched between the connecting pedestal 31 and the corresponding part of the air mover 11 .

This connection method can not only connect the ventilation air bag 121 and the air mover 11 well into one, but also connect the ventilation air bag 121 because the wall 122 of the ventilation air bag 121 is usually flexible. The wall part 127 sandwiched between the pedestal 31 and the corresponding part of the air mover 11 also has a sealing action, in particular the wall 122 of the ventilation air bag 121 is made of polyurethane membrane and cotton flannel. In the situation where the two-layer material is formed, the action is more pronounced.

The connecting pedestal 31 is preferably rigid so that the connecting pedestal 31 can keep pressing the wall portion 127 of the ventilation air bag 121 under the fixing action of the first connecting member 32 . In this case, the outer peripheral edge of the air inlet 123 of the ventilation air bag 121 is coupled to the outer peripheral edge of the outlet of the air mover 11 and thereby exhibits a sealing action.

According to one exemplary embodiment of the present invention, the connecting pedestal 31 may have a structure of a plastic plate, and those skilled in the art may form the connecting pedestal 31 in any format and any material structure. It is possible and through the pressing action generated by the first connecting member 32, the air inlet 123 of the ventilation air bag 121 and the outlet of the air mover 11 can communicate in a relatively closed state from the outside. You just have to understand that you have to do it.

According to one exemplary embodiment of the present invention, preferably, the three first connecting members 32 are uniformly disposed along the circumferential direction of the connecting pedestal 31 . Of course, the number of the first connecting member 32 is not limited to three, and an appropriate number may be selected according to actual demand.

According to one exemplary embodiment of the present invention, as shown in FIG. 2 , the first connecting member 32 may be a locking nail at least partially made of an elastic material, for example, a rubber nail, and the locking nail is formed by a pressing action. It passes through the first connection through-hole 312 , the second connection through-hole 128 , and the third connection through-hole 112 by elastic deformation to form a structure to hold the corresponding member in one place.

In order to form a strong and safe connection, a first engaging structure 321 is installed at one end of a rubber nail, which is one example of the first connecting member 32, and is engaged on the connecting pedestal 31 in the assembled state, and the rubber The nail is provided with an elastically deformable locking protrusion 322 (for example, in the form of a truncated cone) at a position spaced from the end, and the locking protrusion 322 is elastically deformable and pressed to form a first connection through hole ( 312 ), the second connection through-hole 128 and the third connection through-hole 112 , and then at least some of the deformation is restored to the connection pedestal 31 , the wall portion of the ventilation air bag 121 . 127 and a corresponding portion of the air mover 11 may be held tightly between the first engagement structure 321 and the locking protrusion 322 .

Selecting a rubber nail as the first connecting member 32 is simple, simple, and inexpensive, so that the connection can be realized, which is one of the very advantageous connection methods.

However, it should be understood by those skilled in the art that the first connecting member 32 is not limited thereto and any other suitable form may be selected.

Regardless of which type of first connecting member 32 is used, the first connecting member 32 all have a first engaging structure 321 located within the ventilation air bag 121, which has a corresponding structure such as a connecting pedestal ( 31) is interlocked with If the wall portion 127 of the wall 122 of the ventilation air bag 121 is relatively rigid, even the first engaging structure 321 of the first connecting member 32 directly engages the wall portion 127 . can be made to

According to an exemplary embodiment of the present invention, as shown in FIG. 2 , the first engaging structure 321 may form a flange structure.

According to one exemplary embodiment of the present invention, the first engagement structure 321 is a rigid engagement structure.

According to one exemplary embodiment of the present invention, a stereotactic structure may be installed on the air distributor 12 for convenient installation on the positioning and other parts of the air distributor 12 .

3 to 6 show how the air mover 11 according to one exemplary embodiment of the present invention is connected to the air distributor 12 and more specifically to the ventilation air bag 121 in the presence of a spring frame. 3 is an exploded view seen along one gaze direction, FIG. 4 is an exploded view seen along the other gaze direction, and FIG. 5 is a front view in which the air mover 11 is already connected to the ventilation air bag 121 and FIG. 6 is a cross-sectional view of a connection state taken along the cut line AA of FIG. 5 . In these drawings, the same or corresponding members as in FIG. 2 use the same reference numerals as in FIG. 2 .

The vehicle seat is usually provided with a spring frame, and there are some difficulties between the air mover 11 and the air distributor 12 in the presence of the spring frame. As shown in FIG. 3 , the spring frame 4 is positioned between the air mover 11 and the air distributor 12 , so that the air mover 11 must be connected to the air distributor 12 beyond the spring frame 4 . If the spring frame 4 is connected in such a way that the air distributor 12 must be enlarged, the air inlet 123 of the ventilation air bag 121 must be deviated from the air outlet 124, Also, the difficulty of arranging the air distributor 12 is increased.

The connection pedestal 31 of the first connection structure 3 may be disposed inside the ventilation air bag 121 as in the embodiment of FIG. 2 , or may be disposed outside the ventilation air bag 121 . For example, it may be connected to the outside of the ventilated air bag 121 via welding or any other suitable manner. The connecting pedestal 31 may be made of a plastic material, and in this situation, the connecting pedestal 31 can be easily welded to the ventilation air bag 121 , and in particular, can be welded to the outside of the ventilation air bag 121 .

Due to the presence of the spring frame 4, the air inlet ( It is true that it is difficult to realize good adhesion in the outer part close to 123) (the situation in which the connecting pedestal 31 is located inside the ventilated air bag 121), so that the exemplary embodiment is the first connecting structure 3 It further includes a sealing structure (33).

In the situation of the draft airflow generating device 1, such sealing is very necessary, otherwise the airflow will not be well formed on the vehicle seat surface.

The sealing structure 33 includes a first sealing member 331 positioned between the spring frame 4 and the corresponding outer part of the connecting pedestal 31 or the ventilation air bag 121 and the spring frame 4 and the air mover ( 11) may include a second sealing member 332 positioned between.

In the assembled state, as shown in FIG. 6 , under the action of the connecting member 32 , the first sealing member 331 and the second sealing member 332 are pressed between the air mover 11 and the air distributor 12 , and , a corresponding part of the spring frame 4 is inserted between the first sealing member 331 and the second sealing member 332 and further the first sealing member 331 and the second sealing member 332 are in intimate contact As a result, the gas flow path from the air mover 11 to the ventilation air bag 121 is hermetically formed.

In the situation of the draft airflow generating device 1, such sealing is very necessary, otherwise the airflow will not be well formed on the vehicle seat surface.

In the situation of the blowing air flow generating device 1, the requirement for sealing is not high because the air mover 11 blows air into the ventilation air bag 121, so even the sealing structure 33 or the sealing structure 33 part of it can be omitted.

Since the first connecting member 32 passes through the gap of the spring frame 4 when installed, it does not affect the connecting operation.

3-6, the air distributor 12 is positioned between the spring frame 4 and the seat cushion (seat cushion and/or back cushion). In this situation, when a person sits in the vehicle seat, the operating force is transmitted to the spring frame 4 sequentially through the seat seat and the air distributor 12 , and finally the spring frame 4 receives it. Accordingly, the air distributor 12 is located in the path of action of the force and thus is not pressed, which is not an advantageous situation.

For this reason, according to one exemplary embodiment of the present invention, the air distributor 12 is installed on one side of the back side to the cushion of the spring frame 4 so that the air distributor 12 does not receive the cushion transmission force. do.

However, in this situation, since the air distributor 12 cannot have a good engagement with the cushion, there is a difficulty in the fluid flow of the air guiding passage in the cushion, so there is a need for further improvement.

7 and 8 , the second connecting member 51 has a second engaging structure 511 and a communication structure 512 connected to the second engaging structure 511, and the second The engagement structure 511 and the communication structure 512 define an air flow path, and preferably form a central through-hole 513 . In the assembled state, the second engaging structure 511 is located inside the ventilated airbag 121 and engaged with the inside of the ventilated airbag 121 so that it cannot be pulled out from within the ventilated airbag 121 and the communication structure 512 ) and the cushion air guiding passage, to realize the connection of the ventilation air bag 121 and the cushion air guiding passage.

In order to realize a more secure connection, the communication structure 512 may further install at least one locking structure 514 so that the communication structure 512 is locked to a corresponding part of the seat in the assembled state to prevent it from being easily separated. do.

According to one exemplary embodiment of the present invention, as shown in FIGS. 7 and 8 , the second engaging structure 511 may form a flange structure.

According to an exemplary embodiment of the present invention, as shown in FIGS. 7 and 8 , the communication structure 512 may form a tube-shaped structure.

According to an exemplary embodiment of the present invention, the second connecting member 51 may form an integral structure, and in particular, may be a plastic material of integral molding.
