[0005] [Patent Document 1] Japanese Patent Application Publication No. 2023-75727 Summary of the Invention [Problem to be solved by the invention]

[0006] The partition described in Patent Document 1 leaves room for improvement in terms of passenger comfort. [Means for solving the problem]

[0007] A seat partition for solving the above problem comprises a panel that is configured to cover the headrest of the seat from the rear and sides and is attached to the seat, and a blower attached to the panel, and is configured to form an air shield by the air flow blown out from the blower around the head of an occupant sitting in the seat.When the front-to-rear and width directions of the seat are simply defined as the front-to-rear and width directions, the blower is attached to the front of the panel and comprises a cover that forms an intake port and an outlet, and a fan provided inside the cover.When the fan is driven, it is configured to draw air in through the intake port and blow out the air from the outlet.The outlet includes a first outlet that blows out the air flow that forms the air shield, and a second outlet that opens at a position closer to the headrest in the width direction than the first outlet, and is configured so that the flow velocity of the air flow blown out from the second outlet is smaller than the flow velocity of the air flow blown out from the first outlet.

[0008] According to this configuration, an air shield is formed around the head of an occupant seated in the seat by the air flow blown out from the first air outlet. This creates a personal space for the occupant inside the air shield. In addition, an air flow with a flow velocity slower than that of the air flow blown out from the first air outlet is blown out from the second air outlet. The second air outlet opens at a position closer to the headrest in the width direction than the first air outlet. This allows an air flow separate from the air shield to be formed inside the air shield, while the air shield is less likely to be obstructed by the air flow. This contributes to improved comfort for the occupant. [Brief explanation of the drawings]

[0010] Hereinafter, one embodiment of a seat partition (hereinafter referred to as partition 10) will be described with reference to FIGS. As shown in Figures 1 and 4, the partition 10 is applied to a seat 90 of a vehicle.

[0011] The seat 90 of this embodiment serves as a driver's seat for a right-hand drive vehicle. The seat 90 includes a seat cushion 91, a seat back 92, and a headrest 93. Hereinafter, the front-rear direction, width direction, and up-down direction of the seat 90 will be simply referred to as the front-rear direction, width direction, and up-down direction, respectively. In this embodiment, the front-rear direction coincides with the front-rear direction of the vehicle, the width direction coincides with the vehicle width direction, and the up-down direction coincides with the up-down direction of the vehicle.

[0012] 1 and 2, the partition 10 includes a panel 20 and a blower 30. The partition 10 is configured to form an air shield around the head H of an occupant P seated in a seat 90 by an air flow A1 blown out from the blower 30 (see FIG. 4).

[0013] <Panel 20> As shown in FIGS. 1 and 2, the headrest 93 is configured to cover the headrest 93 from the rear and sides and is attached to the seat 90.

[0014] The panel 20 has a main portion 21 configured to cover the headrest 93 from behind, a side portion 22 configured to cover the headrest 93 from the side, and a curved portion 23 connecting the main portion 21 and the side portion 22. The panel 20 is formed from, for example, a transparent synthetic resin.

[0015] 1, the widthwise length of the main portion 21 is greater than the widthwise length of the headrest 93. In addition, the vertical length of the main portion 21 is greater than the vertical length of the headrest 93. The upper end portion of the main portion 21 curves forward. The lower end portion of the main portion 21 covers the upper end portion of the seat back 92 from behind.

[0016] The side portions 22 cover the headrest 93 from the side opposite the driver's door. The length of the side portions 22 in the front-to-rear direction is greater than the length of the headrest 93 in the front-to-rear direction. The length of the side portions 22 in the up-to-down direction is also greater than the length of the headrest 93 in the up-to-down direction. The upper end portions of the side portions 22 curve toward the headrest 93. The lower end portions of the side portions 22 cover the upper end portion of the seat back 92 from the side.

[0017] The upper end of the curved portion 23 is continuously connected to the upper end of the main portion 21 and the upper end of the side portion 22. The lower end of the curved portion 23 is continuously connected to the lower end of the main portion 21 and the lower end of the side portion 22. The lower end of the curved portion 23 covers the upper end of the seat back 92 from diagonally behind.

[0018] The main portion 21 is provided with a mounting portion (not shown) for mounting the panel 20 to the headrest 93. The mounting portion is provided at the lower part of the main portion 21. <Blower device 30> As shown in FIG. 2, the blower 30 includes a cover 31 and a fan .

[0019] The cover 31 is attached to the front surface of the panel 20 and defines an air inlet 32 ​​and an air outlet 33. The air blower 30 is configured to draw air in through the air inlet 32 ​​and blow air out through the air outlet 33 by driving a fan 34.

[0020] The cover 31 of this embodiment has a cover main body 31a that has a shape that bulges forward relative to the front surface of the main portion 21 of the panel 20 and forms an air flow path 35, and mounting portions 31b, 31c that attach the cover 31 to the main portion 21 of the panel 20.

[0021] As shown in FIGS. 1, 2, and 4, the cover 31 extends in the width direction along the front surface of the panel 20. As shown in FIG. 2, the air flow path 35 is formed by the inner surface of the cover body 31a and the front surface of the panel 20.

[0022] The suction port 32 opens on the opposite side of the panel 20 from the side portion 22 in the width direction. The air outlet 33 opens in the width direction toward the side portion 22 of the panel 20. The air outlet 33 is located closer to the side portion 22 than the headrest 93 is in the width direction.

[0023] The mounting portion 31b protrudes upward from the upper end of the cover body 31a. The mounting portion 31c protrudes downward from the lower end of the cover body 31a. The mounting portions 31b and 31c are fastened to the main portion 21 of the panel 20 by a plurality of screws (not shown).

[0024] The fan 34 is provided inside the cover 31, that is, in the air flow path 35. The fan 34 is an electric fan that is driven to rotate by electricity supplied from a battery (not shown). 2 and 3, the air outlet 33 includes a first air outlet 33a that blows out an air flow A1 that forms an air shield, and a second air outlet 33b that opens at a position closer to the headrest 93 in the width direction than the first air outlet 33a. The first air outlet 33a and the second air outlet 33b are formed by dividing the air outlet 33 with a partition wall 31d that extends in the vertical direction.

[0025] The air flow path 35 is a common flow path that communicates with both the first air outlet 33a and the second air outlet 33b. The flow velocity of the airflow A2 blown out from the second air outlet 33b is configured to be smaller than the flow velocity of the airflow A1 blown out from the first air outlet 33a.

[0026] In this embodiment, the opening area of ​​the second air outlet 33b is larger than the opening area of ​​the first air outlet 33a. Next, the operation of this embodiment will be described.

[0027] As shown in Fig. 4, an air shield is formed around the head H of an occupant P seated in the seat 90 by air flow A1 blown out from the first air outlet 33a. This creates a personal space for the occupant P inside the air shield. In addition, an air flow A2 having a flow velocity slower than the flow velocity of the air flow A1 blown out from the first air outlet 33a is blown out from the second air outlet 33b. The second air outlet 33b opens at a position closer to the headrest 93 in the width direction than the first air outlet 33a. This makes it possible to form an air flow A2 separate from the air shield inside the air shield, while preventing the air shield from being obstructed by the air flow A2.

[0028] Next, the effects of this embodiment will be described. (1) The flow velocity of the airflow A2 blown out from the second air outlet 33b is configured to be smaller than the flow velocity of the airflow A1 blown out from the first air outlet 33a.

[0029] According to this configuration, the effects of the above-described embodiment are achieved, which contributes to improving the comfort of the occupant P. (2) The blower 30 has a common air flow path 35 that communicates with both the first air outlet 33a and the second air outlet 33b. The fan 34 is provided in the air flow path 35.

[0030] According to this configuration, an air flow path communicating with the first air outlet 33a and an air flow path communicating with the second air outlet 33b are provided separately, and the configuration of the blower device 30 can be simplified compared to a configuration in which a fan is provided for each air flow path.

[0031] (3) By making the opening area of ​​the second air outlet 33b smaller than the opening area of ​​the first air outlet 33a, the pressure loss at the second air outlet 33b is greater than the pressure loss at the first air outlet 33a. This makes it possible to make the flow velocity of the air flow A2 blown out from the second air outlet 33b smaller than the flow velocity of the air flow A1 blown out from the first air outlet 33a. Therefore, with a simple configuration in which the opening areas of the first air outlet 33a and the second air outlet 33b are made different, the flow velocities of the air flows A1 and A2 at the first air outlet 33a and the second air outlet 33b can be made different.

[0032] <Modification> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0033] A groove extending along the cover body 31a may be provided in the portion of the front surface of the panel 20 facing the cover body 31a. In this case, an air flow path 35 is formed by the groove and the inside of the cover body 31a.

[0034] For example, by providing a resistance portion in second air outlet 33b that increases the airflow resistance compared to first air outlet 33a, the flow velocity of airflow A2 blown out from second air outlet 33b can be made lower than the flow velocity of airflow A1 blown out from first air outlet 33a. In this case, the flow velocities of airflow A1 and A2 can be made different between first air outlet 33a and second air outlet 33b with a simple configuration such as providing a resistance portion in second air outlet 33b.

[0035] As an example of the resistance portion, for example, as shown in FIG. 5 and FIG. 6, a filter having breathability (second filter 37) can be used. 5, the opening area of ​​the first air outlet 33a is the same as the opening area of ​​the second air outlet 33b. A breathable second filter 37 is provided in the second air outlet 33b.

[0036] With this configuration, the pressure loss at the second air outlet 33b is greater than the pressure loss at the first air outlet 33a, so the flow velocity of the airflow A2 blown out from the second air outlet 33b can be made smaller than the flow velocity of the airflow A1 blown out from the first air outlet 33a. Therefore, with a simple configuration such as providing the second filter 37 at the second air outlet 33b, the flow velocities of the airflows A1 and A2 can be made different between the first air outlet 33a and the second air outlet 33b. Furthermore, the airflow A2 can be blown out in a state in which foreign matter has been filtered out by the second filter 37.

[0037] 6, the opening area of ​​the first air outlet 33a and the opening area of ​​the second air outlet 33b are the same. In the second modification, the first air outlet 33a is also provided with a breathable first filter 36. The airflow resistance of the second filter 37 is greater than the airflow resistance of the first filter 36.

[0038] With this configuration, by differentiating the airflow resistance between the first filter 36 and the second filter 37, the flow velocity of the airflow A2 blown out from the second air outlet 33b can be made slower than the flow velocity of the airflow A1 blown out from the first air outlet 33a. Therefore, with a simple configuration in which the airflow resistances of the filters 36, 37 at the first air outlet 33a and the second air outlet 33b are different, the flow velocities of the airflows A1, A2 at the first air outlet 33a and the second air outlet 33b can be made different. Furthermore, the airflows A1, A2 can be blown out in a state in which foreign matter has been filtered out by the first filter 36 and the second filter 37.

[0039] In the first and second modified examples, a configuration in which the opening area of ​​the first air outlet 33a and the second air outlet 33b are the same has been exemplified, but the opening area of ​​the first air outlet 33a and the second air outlet 33b do not have to be the same.

[0040] The resistor is not limited to a filter. For example, the resistor can be formed of a grid or a protrusion. In the above embodiment, an air flow path communicating with the first air outlet 33a and an air flow path communicating with the second air outlet 33b may be provided separately. Also, a fan may be provided for each air flow path. Even in this case, it is sufficient that the flow velocity of the air flow A2 blown out from the second air outlet 33b is configured to be smaller than the flow velocity of the air flow A1 blown out from the first air outlet 33a.
