[0066] Figure 1FIG. 0 is an external perspective view schematically showing the structure of a vehicle seat 1 as an embodiment of the technology of the present invention. Vehicles in this specification include automobiles, airplanes, trams, mobile drones, or ships, etc. In the following description, the front of an occupant sitting on the vehicle seat 1 in a regular posture is referred to as the front direction Fr, the opposite direction of the front direction Fr is referred to as the rear direction Rr, and they are collectively referred to as the front-rear direction. In addition, the right side relative to the occupant when observing the occupant from the rear side is referred to as the right direction R, the left side of the occupant is referred to as the left direction L, and they are collectively referred to as the left-right direction. In addition, the direction perpendicular to the front-rear direction and the left-right direction and the direction from the headrest toward the seat surface side is referred to as the downward direction D, the opposite direction of the downward direction D is referred to as the upward direction U, and they are collectively referred to as the up-down direction. The front-rear direction, the left-right direction, and the up-down direction are mutually intersecting directions.

[0067] The vehicle seat 1 includes a seat cushion 2 that supports the occupant's buttocks and thighs, a seat backrest 3 that supports the occupant's waist and back, and a headrest 4 that supports the occupant's head. In Figure 1 the example, the vehicle seat 1 is a driver's seat side seat or a front passenger seat side seat of an automobile, but it can also be a bench seat of a rear seat, etc.

[0068] The seat cushion 2 has a seat frame (not shown) that forms a skeleton, and the seat frame is covered with a cushion pad 21 made of a soft resin foam material such as polyurethane foam, and further covered with an upholstery 22 including a skin material such as leather, fabric, or non-woven fabric.

[0069] The seat backrest 3 has a seat frame (not shown) that forms a skeleton, and the seat frame is covered with a cushion pad 31 made of a soft resin foam material such as polyurethane foam, and further covered with an upholstery 32 including a skin material such as leather, fabric, or non-woven fabric. An air-conditioning pad 61 for air-conditioning the interior of the vehicle seat 1 is provided inside the seat backrest 3.

[0070] Figure 2 FIG. 15 is a schematic view showing the internal structure of the seat backrest 3. Figure 2 FIG. 17 shows the state of the seat backrest 3 after removing the cushion pad 31 and the upholstery 32. Inside the seat backrest 3, there are provided an air-conditioning pad 61, a blower device 63, a bracket 64 that supports the blower device 63, a seat frame 33 that supports the bracket 64, and a connecting member 62 that connects the bracket 64 and the air-conditioning pad 61. In Figure 2 the example, the seat frame 33 is in a frame shape and has a pair of side frames arranged left and right, a lower frame that connects the lower ends of the pair of side frames, and an upper frame 33U that connects the upper ends of the pair of side frames. The bracket 64 is supported by the upper frame 33U.

[0071] The air-conditioning pad 61 is supported by a support member (not shown) extending from the seat frame 33 and is thus supported on the seat frame 33. The air-conditioning pad 61 can be joined to the cushion pad 31 with an adhesive. The air-conditioning pad 61 has a main body portion 61A having an internally hollow and flat rectangular parallelepiped shape and a flat tubular duct portion 61B extending upward in the U direction from the upper end portion of the main body portion 61A. A plurality of ventilation holes communicating with the interior are provided on the front surface of the main body portion 61A. The duct portion 61B communicates with the interior space of the main body portion 61A. The air-conditioning pad 61 can suck air into the main body portion 61A through the ventilation holes of the main body portion 61A and discharge the sucked air from the duct portion 61B. In this way, the air-conditioning pad 61 constitutes an intake and exhaust unit capable of taking in air through the ventilation holes and discharging air from the duct portion 61B. The duct portion 61B constitutes the exhaust port of the air-conditioning pad 61. The structure of the intake and exhaust unit is not limited to Figure 2 the structure shown, and various structures can be adopted.

[0072] A connecting member 62 connects the duct portion 61B (the exhaust port of the air-conditioning pad 61) to the bracket 64. The connecting member 62 can be integrally formed with the duct portion 61B or can be integrally formed with the bracket 64.

[0073] Figure 3 is Figure 2 an exploded perspective view of the connecting member 62, the air supply device 63, and the bracket 64 shown. Figure 4 is from a direction Figure 3 different from that for observing the perspective view of the air supply device 63 and the bracket 64. Figure 5 is from a direction Figure 3 and Figure 4 different from that for observing the perspective view of the bracket 64. Figure 6 is a view of the bracket 64 observed from the rear side. Figure 7 is a schematic cross-sectional view in a state where the air supply device 63, the bracket 64, and the upper frame 33U are connected.

[0074] The air supply device 63 is a machine that compresses and transports gas by the rotational movement of an impeller or a rotor or the reciprocating movement of a piston. In one example, it can be an electric fan device. In Figure 3 and Figure 4 the example, the air supply device 63 includes: a flat plate 631 made of, for example, metal, the thickness direction of which coincides with the front-rear direction; a substantially cylindrical housing member 632 fixed to the rear surface of the flat plate 631; a rotor 633 housed inside the housing member 632 and rotatably supported by the flat plate 631; and a first cable 634 electrically connected to the rotor 633. A female connector 634A is provided at the end of the first cable 634.

[0075] As an example, an air inlet 632A formed of a circular opening is formed on the rear surface of the housing member 632. On this surface, around the air inlet 632A, in the example of the figure, four engaging claws 632B are provided so as to project in the backward direction Rr. As an example, an air outlet 632C formed of a rectangular opening is formed on the right side surface of the housing member 632. When the air blowing device 63 operates, the rotor 633 rotates to suck air from the air inlet 632A, and the air is discharged from the air outlet 632C.

[0076] The bracket 64 has a structure in which an air flow path 641D (see Figure 5 and Figure 7 ) that connects the air blowing device 63 to the air outlet (duct portion 61B) of the air conditioner mat 61 is provided inside. The bracket 64 includes: a flat plate-shaped planar portion 641 whose thickness direction substantially coincides with the front-rear direction; a U-shaped wall portion 642 that stands upright from the rear surface of the planar portion 641 in the backward direction Rr and is formed in a substantially U shape when viewed in the front-rear direction; and a flat plate-shaped rear surface portion 643 that connects the rear end edges of the U-shaped wall portion 642. The space defined by the planar portion 641, the U-shaped wall portion 642, and the rear surface portion 643 constitutes the air flow path 641D. The planar portion 641, the U-shaped wall portion 642, and the rear surface portion 643 are flow path forming portions that form the air flow path 641D.

[0077] For example, a circular first opening 641B communicating with the air flow path 641D is formed in the planar portion 641. When viewed in the backward direction Rr, the U-shaped wall portion 642 extends from the right end portion and the lower end portion of the planar portion 641 to the left end portion and the lower end portion of the planar portion 641. As Figure 5 shown, a second opening 641C communicating with the air flow path 641D is formed by the lower end edge of the U-shaped wall portion 642, the lower end edge of the planar portion 641, and the lower end edge of the rear surface portion 643. The second opening 641C has a shape corresponding to the connecting member 62, and the connecting member 62 connected to the duct portion 61B is inserted into and engaged with the second opening 641C. As Figure 3 shown, the connecting member 62 is formed in a flanged elongated rectangular tubular shape, and engaging claws 62B are provided on the side surface in the front-rear direction. The end of the duct portion 61B is inserted and fixed into the hollow portion 62A of the connecting member 62. The engaging claws 62B are engaged with engaging recesses (not shown) provided at the lower end portions of the planar portion 641 and the rear surface portion 643 of the bracket 64.

[0078] Figure 4The four engaging claws 632B of the air supply device 63 shown are engaged with the first opening 641B of the flat portion 641. Through this engagement, the air inlet 632A of the air supply device 63 communicates with the air flow path 641D. In addition, as described above, the second opening 641C communicates with the pipe portion 61B by engaging the connecting member 62 therewith. In this way, the bracket 64 has a first opening 641B connected to the air inlet 632A of the air supply device 63 and a second opening 641C connected to the pipe portion 61B of the air conditioner pad 61. Moreover, the directions (the directions perpendicular to the opening surfaces) in which the first opening 641B and the second opening 641C face are different. In the example of the figure, the first opening 641B faces the front direction Fr and the second opening 641C faces the downward direction D.

[0079] Three bosses 641A are erected along the front direction Fr on the peripheral portion of the front surface of the flat portion 641. On the flat plate 631 of the air supply device 63, screw holes are provided at positions corresponding to the bosses 641A, and the screws inserted through the screw holes are fixed to the bosses 641A, whereby the air supply device 63 is fixed to the bracket 64.

[0080] As Figure 4 shown, on the rear portion 643 of the bracket 64, a lower boss BD is erected in the rearward direction Rr for fixing to the upper frame 33U. In addition, on the rear portion 643 of the bracket 64, the following are erected in the rearward direction Rr: a pair of upper ribs RU arranged left and right with the lower boss BD interposed therebetween and a lower rib RD for reinforcement provided below the upper rib RU and the lower boss BD. As Figure 4 shown, the height L1 in the front-rear direction of the upper rib RU is different from the height L2 in the front-rear direction of the lower rib RD, and the height L1 is larger than the height L2. In addition, it is preferable that the height in the front-rear direction of the lower boss BD is the same as the height L1 of the upper rib RU.

[0081] As Figure 4 shown, on the upper side of the U-shaped wall portion 642 in the rear surface of the flat portion 641, at approximately the center in the left-right direction, an engaging claw 644 capable of engaging with the upper frame 33U is erected in the rearward direction Rr. In addition, on the rear surface of the flat portion 641, upper bosses BU are provided to the right and left adjacent to the engaging claw 644 for fixing to the upper frame 33U. On the upper frame 33U, through holes are provided at positions corresponding to the lower boss BD and the two upper bosses BU of the bracket 64 respectively. Screws are inserted through the through holes, and the screws are connected to the lower boss BD and the two upper bosses BU, whereby the bracket 64 is fixed to the upper frame 33U and the bracket 64 is supported by the upper frame 33U.

[0082] As Figure 7As shown, on the upper frame 33U, an engaging hole portion 33H is provided at a position corresponding to the engaging claw 644. When fixing the bracket 64 to the upper frame 33U, first, by engaging the engaging claw 644 with the engaging hole portion 33H, the bracket 64 can be positioned (temporarily fixed) relative to the upper frame 33U. In this state, the upper boss BU and the lower boss BD are respectively arranged face to face with the through holes provided on the upper frame 33U. Therefore, the assembly operation of the bracket 64 to the seat frame 33 can be carried out efficiently.

[0083] As Figure 3 shown, the bracket 64 has a protruding portion 641E that extends from the right end of the upper end portion of the flat portion 641 in the right direction R and the downward direction D. The front surface of the protruding portion 641E and the front surface of the flat portion 641 are substantially in the same position in the front-rear direction. In the bracket 64, a guiding portion G is provided between the protruding portion 641E and the flat portion 641, and the guiding portion G guides the flow of the air discharged from the exhaust port 632C of the air supply device 63 fixed to the bracket 64.

[0084] The guiding portion G is configured to direct the air discharged from the exhaust port 632C of the air supply device 63 in the right direction R downward in the direction D. As Figure 6 shown, the guiding portion G has: a right guiding wall portion 647 that extends from the upper end portion and the right end portion of the flat portion 641 along the protruding portion 641E in the right-lower direction; a left guiding wall portion 646 that extends downward adjacent to the lower end portion and the right end portion of the flat portion 641; a front wall portion 648 that connects the front end edges of the left guiding wall portion 646 and the right guiding wall portion 647; and a flow path adjusting portion 649.

[0085] The right guiding wall portion 647 is erected from the lower end edge 641EA of the protruding portion 641E in the front direction Fr. The right guiding wall portion 647 extends to a position beyond the end 641EB of the protruding portion 641E, and after exceeding the end 641EB, it extends in the downward direction D.

[0086] As Figure 4 shown, the left guiding wall portion 646 is erected from the right end edge of the lower end portion of the flat portion 641 in the front direction Fr. The end edge of the left guiding wall portion 646 and the end edge of the right guiding wall portion 647 are connected by a plate-shaped front wall portion 648 that is substantially perpendicular to the front-rear direction. As Figure 3 shown, it is preferable to provide lattice-shaped reinforcing ribs 648A on the front surface of the front wall portion 648. On the rear surface of the front wall portion 648, near the upper end portion, a flat plate-shaped flow path adjusting portion 649 is erected in the rear direction Rr perpendicular to the up-down direction.

[0087] As Figure 6As shown, a space SP extending in a bending shape toward the lower right direction is defined by a left guide wall portion 646, a right guide wall portion 647, a front wall portion 648, and a flow path adjustment portion 649. In a state where the bracket 64 is fixed to the upper frame 33U, the upper frame 33U is disposed facing the front wall portion 648. Therefore, the space SP abuts against the upper frame 33U through the left guide wall portion 646, the right guide wall portion 647, and the flow path adjustment portion 649, and thus the space SP is in a state of being substantially enclosed by the upper frame 33U.

[0088] The space SP faces the exhaust port 632C of the air supply device 63. When viewed in the left-right direction, the exhaust port 632C is disposed between the flow path adjustment portion 649 and the left guide wall portion 646. Therefore, the air discharged from the exhaust port 632C flows into the space SP between the flow path adjustment portion 649 and the left guide wall portion 646. The air flowing into the space SP flows along the space SP and finally is discharged downward from the space SP in the downward direction D.

[0089] In Figure 6 it, the flow path of the air flowing in from the second opening 641C of the bracket 64 is schematically shown by a dotted arrow. The air flowing in from the second opening 641C reaches the intake port 632A of the air supply device 63 through the air flow path 641D from the first opening 641B. After that, the air is discharged from the exhaust port 632C of the air supply device 63 and moves toward the space SP, flows in the lower right direction, and is discharged in the downward direction D.

[0090] In the above description, the space SP is enclosed by the upper frame 33U, but even when the space SP is not enclosed by the upper frame 33U, the guide portion G can guide the flow of the air discharged from the air supply device 63 so as to direct the air downward in the direction D. In the present embodiment, a substantially C-shaped opening formed by the lower end edge of the left guide wall portion 646, the lower end edge of the front wall portion 648, and the lower end edge of the right guide wall portion 647 constitutes the outlet of the guide portion G (the outlet of the air guided by the guide portion G). This guide portion G is not essential, but by providing the guide portion G, it is possible to control the flow of the air and make it easier to suppress noises during exhaust.

[0091] When the portion of the bracket 64 other than the guiding portion G is defined as the first portion, the guiding portion G has a structure including a second portion (front wall portion 648) located in the forward direction Fr relative to the first portion and a third portion (left guiding wall portion 646 and right guiding wall portion 647) connecting the first portion and the second portion (front wall portion 648). By providing the guiding portion G, the front wall portion 648 can thus be utilized to bear the load from the forward direction Fr, and accordingly, the strength of the bracket 64 can be enhanced. Further, it is preferably configured such that, in a state where the air supply device 63 is fixed to the bracket 64, the flat plate 631 of the air supply device 63 and the front wall portion 648 of the bracket 64 are disposed at substantially the same position in the front-rear direction. In this way, the front wall portion 648 and the air supply device 63 can bear the load from the forward direction Fr with a larger surface area, and the load can be efficiently released to the seat frame 33.

[0092] As Figure 3 shown, a second cable 50 is provided on the vehicle seat 1, and the second cable 50 connects the first cable 634 of the air supply device 63 to the electrical wiring of the vehicle. The proximal end of the second cable 50 is connected to, for example, a control device built in the vehicle body through the interior of the vehicle seat 1. A male connector 50A is provided at the distal end of the second cable 50, and by connecting the male connector 50A to the female connector 634A of the first cable 634, the air supply device 63 can be driven from the above-mentioned control device or the like.

[0093] As Figure 4 shown, on the bracket 64, an engaging hole H1 penetrating in the front-rear direction is provided at the upper end of the planar portion 641 facing the air supply device 63. An engaging protrusion 634B that engages with the engaging hole H1 is provided on the female connector 634A of the first cable 634. By engaging the engaging protrusion 634B with the engaging hole H1, the first cable 634 is thus supported by the bracket 64. The engaging hole H1 provided on the bracket 64 constitutes a first support portion for supporting the first cable 634. Further, the engaging hole H1 may be replaced with an engaging protrusion, and the engaging protrusion 634B may be constituted by an engaging hole that engages with the engaging protrusion. The engaging hole does not need to be a through hole and may be a recess or the like.

[0094] As Figure 6 shown, an engaging hole H2 penetrating in the front-rear direction is provided in the protruding portion 641E of the bracket 64. A C-shaped clip 51 (see Figure 5 ) is installed on the second cable 50, and an engaging protrusion 51A integrated with the clip 51 engages with the engaging hole H2, whereby the second cable 50 is supported by the bracket 64. The engaging hole H2 provided on the bracket 64 constitutes a second support portion for supporting the second cable 50. The engaging hole H2 may be replaced with an engaging protrusion, and the engaging protrusion 51A may be constituted by an engaging hole that engages with the engaging protrusion. The engaging hole does not need to be a through hole and may be a recess or the like.

[0095] As Figure 5 shown, the second cable 50 supported by the protruding portion 641E of the bracket 64 is arranged along the right guide wall portion 647. The protruding height (the length in the front-rear direction) of the right guide wall portion 647 protruding from the protruding portion 641E is preferably smaller than the outer diameter of the second cable 50. In this way, the second cable 50 can be arranged at a position rearward of the front wall portion 648, and the second cable 50 can be protected from the impact on the bracket 64 from the front side.

[0096] As Figure 4 and Figure 5 shown, a cable locking portion 650 for locking the second cable 50 is provided at the lower end portion of the right guide wall portion 647. The cable locking portion 650 includes: a locking plate 650A having a C-shaped cross section, which extends forward from the rear end edge of the right guide wall portion 647; and two locking claws 650B, which are provided at the front end edge of the right guide wall portion 647 so as to be separated in the vertical direction. A portion of the second cable 50 on the proximal end side with respect to the portion supported by the clip 51 on the bracket 64 is clamped by the locking plate 650A and the locking claws 650B, whereby the second cable 50 is locked to the bracket 64.

[0097] By providing the cable locking portion 650 on the bracket 64, the position of the second cable 50 can be stabilized. In addition, the locking plate 650A is configured to cover the rear side of the second cable 50 and is located between the upper frame 33U and the second cable 50. Therefore, the second cable 50 can be protected by the locking plate 650A against the load from the upper frame 33U. It should be noted that, in a portion of the second cable 50 above the cable locking portion 650, the protruding portion 641E is present between the second cable 50 and the upper frame 33U. Therefore, the second cable 50 can be protected by the protruding portion 641E.

[0098] In the vehicle seat 1 configured as described above, for example, the assembly is performed as follows. First, the upper frame 33U and the bracket 64 are fixed by screw fixation. Next, the air supply device 63 is fixed to the bracket 64 by screw fixation. At this time, the engagement hole H1 of the bracket 64 and the engagement protrusion 634B of the first cable 634 of the air supply device 63 are also engaged. Next, the clip 51 is attached to the second cable 50, and the male connector 50A and the female connector 634A are connected. Next, the engagement protrusion 51A and the engagement hole H2 are engaged, and the second cable 50 and the cable locking portion 650 are locked. Finally, the second opening 641C of the bracket 64 and the connecting member 62 are connected.

[0099] According to this embodiment, the bracket 64 has an air flow path 641D and also functions as a support member for the second cable 50. Therefore, compared with the conventional structure, the number of components can be reduced or the size of the bracket 64 can be decreased, and cost reduction, miniaturization, and weight reduction of the bracket 64 can be achieved.

[0100] In the above description, an example in which the air-conditioning pad 61, the connecting member 62, the air supply device 63, the bracket 64, and the second cable 50 are provided inside the seat back 3 has been shown. However, the air-conditioning pad 61, the connecting member 62, the air supply device 63, the bracket 64, and the second cable 50 may be provided inside the seat cushion 2, or may be provided inside each of the seat cushion 2 and the seat back 3.

[0101] As described above, the following matters are disclosed in this specification. The corresponding components and the like in the above-described embodiments are described in the following parentheses, but are not limited thereto. (1)

[0103] A vehicle seat, comprising:

[0104] An intake and exhaust unit (air-conditioning pad 61) that performs intake and exhaust;

[0105] An air supply device (air supply device 63); and

[0106] A bracket (bracket 64) that supports the air supply device, wherein

[0107] The bracket has an air flow path (air flow path 641D) inside that connects the air supply device and an exhaust port (pipe portion 61B) of the intake and exhaust unit.

[0108] According to (1), when the bracket required for supporting the air supply device is used to allow air to flow from the intake and exhaust unit to the air supply device, the structure from the intake and exhaust unit to the air supply device can be simplified. For example, compared with a structure in which a component forming an air flow path from the intake and exhaust unit to the air supply device is separately provided from the bracket and the bracket is used to support the component, the component is not required, and thus the bracket can also be reduced, which can contribute to weight reduction, miniaturization, and cost reduction of the vehicle seat. (2)

[0110] The vehicle seat according to (1), wherein

[0111] The bracket has a first opening (first opening 641B) connected to an intake port (intake port 632A) of the air supply device and a second opening (second opening 641C) connected to an exhaust port (pipe portion 61B) of the intake and exhaust unit,

[0112] The first opening and the second opening face different directions.

[0113] According to (2), the orientation of the air discharged from the intake and exhaust unit can be changed by the bracket, so that the structure from the intake and exhaust unit to the air supply device can be simplified. In addition, even when the bracket is fixed to, for example, the seat frame, it can be easily achieved. (3)

[0115] The vehicle seat according to (2), wherein

[0116] The first opening faces forward of the vehicle seat,

[0117] The second opening faces downward of the vehicle seat.

[0118] According to (3), the structure inside the seat can be simplified. (4)

[0120] The vehicle seat according to any one of (1) to (3), wherein

[0121] The bracket has a guiding portion (guiding portion G) for guiding the flow of the air discharged from the air supply device.

[0122] According to (4), by providing the guiding portion, the flow of the air can be controlled, and it is easier to suppress the sound during exhaust. In addition, by providing the guiding portion, the strength of the bracket can be improved accordingly. (5)

[0124] The vehicle seat according to (4), wherein

[0125] The bracket has a first opening (first opening 641B) connected to the air inlet (air inlet 632A) of the air supply device and a second opening (second opening 641C) connected to the exhaust port (pipe portion 61B) of the intake and exhaust unit,

[0126] The outlet of the guiding portion and the second opening face the same direction.

[0127] According to (5), the structure inside the seat can be simplified. (6)

[0129] The vehicle seat according to (4) or (5), wherein

[0130] The outlet of the guiding portion faces downward of the vehicle seat.

[0131] According to (6), since there is often a surplus of space under the seat, it is easy to form an air discharge passage. Thus, the space utilization efficiency inside the seat can be improved, contributing to weight reduction and miniaturization. (7)

[0133] The vehicle seat according to any one of (4) to (6), wherein,

[0134] The bracket has: a first part (the part other than the guide part G), which includes a flow path forming part (a flat part 641, a U-shaped wall part 642, and a rear part 643) having the air flow path therein and facing the air supply device; a second part (a front wall part 648), which is located in front of the first part with respect to the vehicle seat; and a third part (a left guide wall part 646 and a right guide wall part 647), which connects the first part and the second part,

[0135] The guide part is configured to include the second part and the third part.

[0136] According to (7), the load from the front of the seat can be borne by the second part constituting the guide part, and the strength of the bracket can be improved. In addition, when the surface on the front side of the seat of the air supply device disposed in the flow path forming part and the second part of the bracket are substantially flush, the load from the front of the seat can be borne by a relatively large surface area of the second part and the front surface of the air supply device. When the bracket is supported by the seat frame, the load can be efficiently released to the seat frame. (8)

[0138] The vehicle seat according to (7), wherein,

[0139] Comprising: a seat frame (seat frame 33)

[0140] The bracket is supported by the seat frame in a state where a space divided by the second part and the third part is closed by a part (upper frame 33U) of the seat frame.

[0141] According to (8), the air flow can also be controlled by the seat frame, and the air flow can be controlled with high precision. By using the seat frame, simplification of the structure, weight reduction, and cost reduction of the bracket can be achieved.
