In the following description, “car 1” and “vehicle seat 2” will be described as examples of “vehicle” and “vehicle seat”. In the following description, the top, bottom, front, back, left, and right are the top, bottom, front, back, left, and right directions described in the above-described figure, that is, the state assembled to the automobile 1. The orientation of the vehicle seat 2 when used as a reference.

  First, with reference to FIGS. 1-2, the structure of the vehicle seat 2 is demonstrated. The vehicle seat 2 is, for example, a known tumble type (foldable and retractable type) rear seat, and the seat cushion 10 and a seat that can tilt with respect to the seat cushion 10 via a recliner (not shown). And back 40. In addition, since this vehicle seat 2 is a bench type (a chaise lounge type that extends in the left-right direction), for convenience of illustration, only the right side seat is shown, and the left side seat is omitted. ing. Hereinafter, the seat cushion 10 and the seat back 40 will be described individually.

  First, the seat cushion 10 will be described (see FIGS. 1-2, 4). The seat cushion 10 includes a seat cushion frame 12 formed in a substantially rectangular frame shape, a seat cushion pad 14 assembled so as to cover the seat cushion frame 12, and a surface (design surface) of the seat cushion pad 14. And a seat cushion cover (not shown) for covering.

  A plurality (eight in this example) of air outlets 14 a are formed on the seating surface of the seat cushion pad 14. A flow path 16 is formed in the seat cushion pad 14 and communicates with the plurality of air outlets 14a. The plurality of air outlets 14 a are outlets of the flow path 16, and the inlet 16 a of the flow path 16 is formed below the seat cushion pad 14.

  The inlet 16 a of the flow path 16 is connected to an air conditioner 30 assembled on the floor 3 via a hose-shaped first duct 32. The first duct 32 is formed long enough to be able to cope with folding and storing the vehicle seat 2. Thereby, when the air conditioner 30 is operated, the air-conditioning air (hot air or cold air) A can be blown out from the plurality of outlets 14 a via the first duct 32 and the flow path 16. Therefore, the seating environment of the seated person (not shown) can be kept good as in the prior art.

  A through hole 18 is formed in the rear portion of the seat cushion pad 14 so as to penetrate the thickness direction thereof. The inlet 18 a of the through hole 18 is connected to the air conditioner 30 via a hose-shaped second duct 34. The second duct 34 is also formed long enough to accommodate the vehicle seat 2 when folded. Note that the second duct 34 is disposed outside the seat cushion pad 14 as is apparent from FIG.

  On the other hand, the seat cushion side cylinder member 20 is assembled to the outlet 18b side of the through hole 18 so as to be inserted (see FIGS. 2 to 3). Thereby, even if a seated person's load is applied to the seat cushion pad 14, it can control that the seat cushion pad 14 bends greatly. Therefore, the outlet 18b of the through hole 18 can be prevented from being blocked. When the seat cushion side cylinder member 20 is assembled in this way, the inner surface of the through hole 18 on the outlet 18b side is in a state where the seat cushion pad 14 is exposed.

  Further, the inner diameter of the outlet 18 b of the through hole 18 is set smaller than the outer diameter of the seat cushion side cylinder member 20. Therefore, it is difficult for the inserted seat cushion side cylinder member 20 to be removed from the outlet 18 b of the through hole 18. Further, the outlet 18b side of the through hole 18 has a shape in which the rear upper side of the seat cushion pad 14 is raised so as to cover the periphery of the inlet 46a of the flow path 46 of the seat back pad 44 described later. The seat cushion 10 is configured in this way.

  Next, the seat back 40 will be described (see FIGS. 1 and 2 and 5). The seat back 40 also has a seat back frame 42 formed in a substantially rectangular frame shape, a seat back pad 44 assembled so as to cover the seat back frame 42, and a surface (design surface) of the seat back pad 44. And a seat back cover (not shown) for covering.

  A plurality (seven in this example) of air outlets 44 a are formed on the back surface of the seat back pad 44. A flow path 46 is formed inside the seat back pad 44 and communicates with the plurality of air outlets 44a. The plurality of air outlets 44 a serve as outlets of the flow path 46, and the inlet 46 a of the flow path 46 is located below the seat back pad 44 so as to face the outlet 18 b of the through hole 18 of the seat cushion pad 14. Is formed.

  In other words, the outlet 18 b of the through hole 18 of the seat cushion pad 14 is formed to face the inlet 46 a of the flow path 46 of the seat back pad 44. Accordingly, when the air conditioner 30 is operated, the air-conditioning air (warm air or cold air) A can be blown out from the plurality of outlets 44a through the second duct 34, the through hole 18 and the flow path 46. it can. At this time, unlike the prior art, the second duct 34 is disposed outside the seat cushion pad 14.

  Therefore, warm air and cold air of the air-conditioning air A are not taken away by the seat cushion pad 14. Therefore, the air-conditioning air A blown out from the plurality of outlets 44a of the seat back 40 does not become warm (raw lukewarm). As a result, the seating environment of the seated person can be kept good as in the prior art. At this time, the air-conditioning air A is supplied to the flow path 46 of the seat back pad 44 through the seat cushion pad 14 (specifically, the through hole 18 of the seat cushion pad 14), as in the prior art. ing.

  Therefore, the supply port of the air-conditioning air A does not appear on the design surface of the seat back 40. Accordingly, it is possible to prevent the appearance of the vehicle seat 2 from being damaged. A bezel 46b having a lattice is assembled to the edge of the inlet 46a of the flow path 46. Thereby, it is possible to prevent foreign matter from entering the flow path 46. Moreover, it is assembled | attached to the inlet 46a of this flow path 46 in the appearance where the seat back side cylinder member 50 is inserted (refer FIGS. 2-3).

  Thereby, even if a seated person's load is applied to the seat back pad 44, it can control that the seat back pad 44 bends greatly. Therefore, the inlet 46a of the flow path 46 can be prevented from being blocked. The inner diameter of the inlet 46 a of the flow path 46 is set to be smaller than the outer diameter of the seat back side cylinder member 50. Therefore, the inserted seat back side cylinder member 50 is difficult to be removed from the inlet 46 a of the flow path 46. The seat back 40 is configured in this way.

  The vehicle seat 2 according to the embodiment of the present invention is configured as described above. According to this structure, the through-hole 18 is formed in the rear part of the seat cushion pad 14 so that the thickness direction may be penetrated. The inlet 18 a of the through hole 18 is connected to the air conditioner 30 via a hose-shaped second duct 34. The second duct 34 is disposed outside the seat cushion pad 14. Further, the outlet 18 b of the through hole 18 of the seat cushion pad 14 is formed to face the inlet 46 a of the flow path 46 of the seat back pad 44. Therefore, when the air conditioner 30 is operated, air-conditioning air (warm air or cold air) A can be blown out from the plurality of outlets 44a through the second duct 34, the through hole 18 and the flow path 46. . At this time, unlike the prior art, the second duct 34 is disposed outside the seat cushion pad 14. Therefore, warm air and cold air of the air-conditioning air A are not taken away by the seat cushion pad 14. Therefore, the air-conditioning air A blown out from the plurality of outlets 44a of the seat back 40 does not become warm (raw lukewarm). As a result, the seating environment of the seated person can be kept good as in the prior art.

  Further, according to this configuration, the air-conditioning air A is provided in the flow path 46 of the seat back pad 44 via the seat cushion pad 14 (specifically, the through-hole 18 of the seat cushion pad 14), as in the related art. Is supplied. Therefore, the supply port of the air-conditioning air A does not appear on the design surface of the seat back 40. Accordingly, it is possible to prevent the appearance of the vehicle seat 2 from being damaged.

  Further, according to this configuration, the seat cushion side cylindrical member 20 is assembled in a manner to be inserted into the outlet 18 b of the through hole 18 of the seat cushion pad 14. Thereby, even if a seated person's load is applied to the seat cushion pad 14, it can control that this seat cushion pad 14 bends greatly. Accordingly, the outlet 18b of the through hole 18 of the seat cushion pad 14 can be prevented from being blocked. Further, according to this configuration, the seat back side tubular member 50 is assembled in a state of being inserted into the inlet 46 a of the flow path 46 of the seat back pad 44. Thereby, even if a seated person's load is applied to the seat back pad 44, it can control that this seat back pad 44 bends greatly. Therefore, the entrance 46a of the flow path 46 of the seat back pad 44 can be prevented from being blocked.

  According to this configuration, the inner surface of the through hole 18 on the outlet 18b side is in a state where the seat cushion pad 14 is exposed. Therefore, when the vehicle seat 2 is folded and stored, it is possible to prevent abnormal noise and wear caused by the seat cushion side cylinder member 20 coming into contact with the hard material (for example, the bezel 46b) of the seat back 40.

  In addition, according to this configuration, the outlet 18b side of the through hole 18 has a shape in which the upper rear side of the seat cushion pad 14 is raised so as to cover the periphery of the inlet 46a of the flow path 46 of the seat back pad 44. Yes. Therefore, the through hole 18 of the seat cushion 10 and the flow path 46 of the seat back 40 can be sealed. Therefore, the conditioned air A emitted from the air conditioner 30 can be reliably supplied to the flow path 46 of the seat back 40. As a result, the conditioned air A can be reliably blown out from the air outlet 44a of the seat back 40.
