  In a vehicle seat such as Patent Document 1, it is well known to provide devices such as a blower and a heater device for seat air conditioning. In order to install such a device on a vehicle seat, it is required to secure the mounting space. Furthermore, in recent years, the space in the vehicle interior has been demanded, and the position of the vehicle seat tends to be lowered. Therefore, the distance between the seat and the floor surface is reduced, and it is difficult to secure an installation space for the device.

  On the other hand, in the lower space of the vehicle seat, it is possible to ensure a relatively small space just below the tilt pan located at the front portion of the seating seat portion. Since this tilt pan is configured to be adjustable in a tilted posture so that the front side is raised, the tilting operation can adjust the posture of the seating seat portion.

  And when it is going to apply the structure which mounts an apparatus to a tilt pan with respect to the apparatus of patent document 1, the front side seat wire hold | maintained at a fixing bracket comprises the member tilted as a part of tilt pan, and the rear side The seat wire constitutes a member that does not tilt separately from the tilt pan. That is, according to the tilting movement of the tilt pan, the front seat wire tilts together with the tilt pan, but the rear seat wire remains stationary regardless of this tilt.

  In this case, since the bracket for holding the rear seat wire in Patent Document 1 has a holding structure that cannot follow this movement when the front seat wire tilts, a configuration in which a device is actually mounted on the tilt pan is patented. There is a problem that it cannot be applied to Document 1.

  Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle seat device that achieves both a holding structure capable of handling a tilting operation of a seating seat portion and device mounting ability. That is.

  The present invention employs the following technical means in order to achieve the aforementioned object. It should be noted that the reference numerals in parentheses described in the claims and in this section are examples showing the correspondence with the specific means described in the embodiments described later as one aspect, and the technical scope of the present invention is as follows. It is not limited.

(First embodiment)
A first embodiment to which the present invention is applied will be described with reference to FIGS. The vehicle seat device 1 to which the present invention is applied has a function of blowing air and a function of providing heating heat to the back, hips, and thighs of the occupant sitting on the seat. As shown in FIG. 1, the vehicle seat device 1 includes a seat back portion 2 that supports the back portion of the occupant and a seating seat portion 3 that supports the buttocks of the occupant.

  The vehicle seat device 1 includes at least a seating seat portion 3 including parts used for seat air conditioning. Examples of the component include a blower that blows air, a heater device that releases heat, and a duct that guides the flow of air.

  The seating seat portion 3 is equipped with a blower 4 that blows air toward the passenger as an example of a seat air conditioning component. Moreover, you may make it mount the air blower which ventilates air toward a passenger | crew also in the seat back part 2. FIG.

  The blower 4 has a high pressure loss in the air passage 31a formed in the seat pad 31 disposed in the seating seat portion 3, and therefore, a sirocco fan that is rotationally driven by a motor is disposed inside the scroll-shaped casing. . The axial direction of the sirocco fan is directed in the vehicle vertical direction. The casing 40 is formed with an air inlet at the bottom of the vehicle. The air intake port of the blower 4 sucks vehicle interior air from the space near the floor surface 6 in the vehicle interior below the seat pad 31 when the sirocco fan is driven. Air blown by the blower 4 is blown toward the skin member 30 of the seat pad 31 through the air passage 31a, and air is blown from the blowout opening 30a made up of a large number of small holes opened in the skin member 30 as shown by arrows in FIG. It is blown out toward the occupant's body as shown in. The blower 4 is displaced up and down together with the tilt pan 32 and the bracket 5 by the operation of a tilt mechanism described later.

  A duct portion 41 is connected to an end portion of the casing 40 in the centrifugal direction of the sirocco fan. The duct portion 41 is, for example, a bellows-like duct that forms a passage through which air blown from the sirocco fan flows. The duct portion 41 is formed of, for example, a resin material, and the material itself may be a material having elasticity.

  Further, in the seat pad 31 and the seat back portion 2, an electric heater may be disposed on the back side of the skin member 30. According to this electric heater, when the electric heater is energized during the heating in winter, the hot air heated by the electric heater can be blown out from the blowing opening of the skin member 30, and the skin member itself can also be heated. it can.

  The seating seat 3 includes a seat pad 31 on the back side of the skin member 30, and a seat wire 33 on the back side of the seat pad 31. The skin member 30 is made of leather or fabric. The seat pad 31 is made of an elastically deformable material, and specifically, is an elastic resin material such as, for example, an open-cell foamed polyurethane. The seat pad 31 is a portion that has a sufficiently large thickness dimension as compared with the skin member 30 and exhibits a cushioning function of the seat.

  The seat wire 33 is an example of a linear member having a circular cross section made of a spring steel material, and supports the seat pad 31. The seat wire 33 is fixed to the frame, which is a skeleton member of the seating seat portion 3, so as to have a certain tension. In the frame, a plurality of seat wires 33 are arranged so as to repeat S-shaped refraction in the vehicle longitudinal direction. As a result, the seat pad 31 and the like are supported by the seat wire 33 and the like as an example of a pad support member so that deformation such as bending is possible.

  The frame that is a skeleton member of the seating seat portion 3 includes a tilt pan 32, a stationary lot portion 34, and a fulcrum lot portion 35. The stationary lot portion 34 is a member that remains stationary even when the tilt pan 32 tilts, and is configured integrally with the front end portion of the seat wire 33 to support the seat wire 33 on the front side. The fulcrum lot portion 35 is configured integrally with the rear end portion of the sheet wire 33 and supports the sheet wire 33 on the rear side. The fulcrum lot portion 35 is a columnar tilt support member at the rear portion of the frame, which is disposed in a state where the axial direction is along the sheet width direction. The stationary lot portion 34 is a cylindrical holding member that is positioned in front of the fulcrum lot portion 35 and is disposed in a state where the axial direction is along the sheet width direction.

  The vehicle seat device 1 can adjust the vertical position of the front portion of the seating seat portion 3 by moving the front portion side of the tilt pan 32 up and down by a tilt mechanism incorporated in the frame. The vehicle seat device 1 includes a fulcrum lot portion 35 that is provided below the seat pad 31 and operates as a fulcrum of tilt when the tilt pan 32 tilts so that the front side of the tilt pan 32 is raised. The fulcrum lot portion 35 is supported by bearing members and bolt members provided on the left and right in the sheet width direction so that both ends in the axial direction can rotate about the axis.

  The fulcrum lot portion 35 is connected to the tilt pan 32 by, for example, a link member. With such a configuration, when the operation handle is rotated, the rotation angle of the fulcrum lot portion 35 that rotates around the axis changes, and the tilt pan 32 is linked to the rotation angle of the fulcrum lot portion 35 in front of it. The side moves up and down. Therefore, the tilt pan 32 is a member at the front portion of the frame, and is provided so as to be tiltable at the front portion of the seat pad 31 by a tilt mechanism. According to this tilt mechanism, the front portion of the seating seat portion 3 can be tilted with the fulcrum lot portion 35 located behind the tilt pan 32 as a fulcrum. According to this tilting operation, it is possible to adjust to a fine seat posture.

  The vehicle seat device 1 includes a bracket 5 to which the above-described components for seat air conditioning are fixed and which is displaced integrally with the tilt pan 32 as the tilt pan 32 tilts. Further, the bracket 5 may be integrated with a part for seat air conditioning and configured as a part of the part. The bracket 5 is a member that is installed on the lower side of the seat pad 31 and fixes a component for seat air conditioning to the lower side of the seating seat portion 3.

  The bracket 5 is fixed to the front fixing part 52 fixed to the tilt pan 32, the hook part 50 positioned behind the front fixing part 52 and hooked to the stationary lot part 34, and the air blower 4 which is a part for seat air conditioning. And a component fixing portion 51 to be formed. The blower 4 is fixed to the component fixing portion 51 by a fastening structure using bolts and screws. The bracket 5 is a plate-like member formed of, for example, a stainless steel plate or a galvanized steel plate. Further, the bracket 5 is provided with a screw hole such as a burring for screwing the blower 4. Moreover, the bracket 5 may be manufactured by press work, or may be a resin molded product manufactured using a mold.

  The component fixing portion 51 is located below the front fixing portion 52 and the hook portion 50 and is also a portion that connects the front fixing portion 52 and the rear hook portion 50. As shown in FIGS. 2 and 4, the blower 4 is installed so as to be suspended from the tilt pan 32 and the stationary lot portion 34 via the bracket 5. In other words, the bracket 5 hangs below the seat pad 31 such that the front side fixing portion 52 is fixed to the tilt pan 32 and the hook portion 50 is hooked on the stationary lot portion 34. The blower 4 is located between the bracket 5 and the floor surface 6 and is accommodated in a space below the tilt pan 32 formed between the tilt pan 32 and the floor surface 6. 2 and 4 to 6 are views showing the seat pad 31 and its lower side as viewed from the side.

  The hook portion 50 has a C-shaped vertical cross section so as to connect the upper support portion 500 positioned on the upper side and the lower support portion 501 positioned on the lower side so as to face the upper support portion 500. It is. The distance between the upper support portion 500 and the lower support portion 501 is set to be larger than the outer diameter of the stationary lot portion 34.

  Since the hook section 50 has a C-shaped vertical cross section, an open section 502 that allows the hook section 50 to be attached to and detached from the stationary lot section 34 is provided between the upper support section 500 and the lower support section 501. Provided. The open portion 502 is formed such that the open length, for example, the distance between the upper support portion 500 and the lower support portion 501 is larger than the outer diameter of the stationary lot portion 34. According to the configuration having the opening portion 502, the hook portion 50 is detached from the stationary lot portion 34 in the direction in which the hook portion 50 and the stationary lot portion 34 are separated, or the stationary lot portion 34 is hooked inside the hook portion 50. be able to. Therefore, the hook portion 50 can be hooked or dropped from the stationary lot portion 34.

  2 and 4 show a first holding state in which the holding relationship between the hook portion 50 and the stationary lot portion 34 is maintained and the tilt pan 32 is not tilted. 5 shows a second holding state in which the holding relationship between the hook portion 50 and the stationary lot portion 34 is maintained, the front side of the tilt pan 32 is raised from the first holding state, and the tilt pan 32 is tilted. ing. The hook portion 50 includes relative displacement means for relatively displacing the stationary lot portion 34 with respect to the hook portion 50 while maintaining the holding relationship from the first holding state to the second holding state. The relative displacement means described above includes an upper support portion 500 and a lower support portion 501. Here, the second holding state may be a state when the tilt pan 32 is tilted to the maximum extent, or may be a state between the first tilting state and the maximum tilting state.

  As shown in FIGS. 2 and 4, in the first holding state, the upper support portion 500 contacts the upper surface of the stationary lot portion 34 and is caught by the stationary lot portion 34. The lower support portion 501 is separated from the outer peripheral surface of the stationary lot portion 34, and a gap 503 having a predetermined size is formed between the lower support portion 501 and the lower surface of the stationary lot portion 34. ing. The gap 503 has a length that extends in the opening direction of the opening 502 that allows the hook 50 to be attached to and detached from the stationary lot 34, that is, in the direction that intersects the insertion or removal direction. The intersecting direction is, for example, the vertical direction, and is the direction in which the upper support portion 500 and the lower support portion 501 face each other.

  The gap 503 corresponds to a range in which the stationary lot portion 34 can be displaced relative to the hook portion 50 in the process in which the tilt pan 32 tilts from the first holding state. Further, it is preferable that the length of the crossing direction in the gap 503 is set to be equal to or longer than the length by which the stationary lot portion 34 can be displaced relative to the hook portion 50.

  As shown in FIG. 5, in the second holding state, the upper support portion 500 is separated from the upper surface of the stationary lot portion 34, and the distance between the lower support portion 501 and the lower surface of the stationary lot portion 34 is the first. It is smaller than the holding state. Even in the second holding state, the stationary lot portion 34 is located between the upper support portion 500 and the lower support portion 501, so that the holding relationship between the stationary lot portion 34 and the hook portion 50 is maintained. Furthermore, this holding relationship is strengthened by the stationary lot portion 34 being in contact with the connecting portion connecting the upper support portion 500 and the lower support portion 501 from the first holding state to the second holding state. Is done. In other words, the bracket 5 is held while corresponding to the tilting of the tilt pan 32 by relative displacement between the upper support portion 500 and the lower support portion 501 while the stationary lot portion 34 contacts a part of the hook portion 50. Can continue to function.

  In addition, the air conditioning component including the blower 4 is installed in front of the stationary lot portion 34. This configuration contributes to the fact that the seat wire 33 does not contact the air-conditioning component even when the seat wire 33 is bent due to an impact, a load, or the like and deformed to the front side, as shown by a two-dot chain line in FIG.

  The air conditioning component including the blower 4 is installed behind the front part of the tilt pan 32 and ahead of the stationary lot part 34. This configuration can prevent the hand from touching the air-conditioning component when the occupant puts his hand between the seating seat portion 3 and the floor surface 6 by groping.

  Below, the effect which the vehicle seat apparatus 1 of 1st Embodiment brings is demonstrated. The vehicle seat device 1 includes a tilt pan 32, a fulcrum lot portion 35 that is a tilt support member, a bracket 5 that installs a seat air-conditioning component below the seating seat portion 3, and a holding device that holds the bracket 5. And a stationary lot part 34 as a member. The tilt pan 32 is provided at the front portion of the seat pad 31 and is configured to be tiltable. The fulcrum lot portion 35 is provided below the seat pad 31 and operates as a fulcrum for tilting when the tilt pan 32 tilts so that the front side is raised.

  The bracket 5 has a seat air-conditioning component fixed thereto, or is configured integrally with the component, and is displaced integrally with the tilt pan 32 as it tilts. The stationary lot portion 34 is formed integrally with the seat wire 33 that supports the seat pad, and maintains a stationary state even when the tilt pan 32 is tilted by the hook portion 50 provided on the bracket 5 being hooked. The fulcrum lot portion 35 is provided behind the stationary lot portion 34. The hook portion 50 maintains the holding relationship between the bracket 5 and the stationary lot portion 34 and maintains the holding relationship from the first holding state to the hook portion 50 over the second holding state. Relative displacement means for relative displacement is provided.

  According to this configuration, the stationary lot portion 34 and the hook portion 50 can be relatively displaced by the relative displacement means provided in the hook portion 50 from the tilt pan 32 to the tilted state. With this function, the bracket 5 can be held following the tilting operation of the tilt pan 32. The vehicle seat device 1 achieves both a holding structure that enables the tilt pan 32 to be tilted and a seat air-conditioning component installed below the tilt pan 32. In addition, the holding structure for holding the bracket 5 includes at least a portion that is integral with the front tilt pan 32 and a hook portion 50 that is hooked on the stationary lot portion 34, so that stable holding that is not cantilevered is realized. can do. Further, the arrangement in which the fulcrum lot portion 35 is provided behind the stationary lot portion 34 allows the angle range in which the tilt pan 32 can be tilted to be set large. As described above, the vehicular seat device 1 makes it possible to achieve both the holding structure that can cope with the tilting operation of the seating seat portion 3 and the device mountability.

  The relative displacement means includes an upper support portion 500 provided on the upper side and a lower support portion 501 provided on the lower side of the upper support portion 500 so as to face the upper support portion 500. Is done. In the first holding state, a gap 503 is formed between the stationary lot portion 34 that contacts the upper support portion 500 and the lower support portion 501 so that the stationary lot portion 34 can be relatively displaced with respect to the hook portion 50. ing.

  According to this configuration, the stationary lot portion 34 can be relatively displaced with respect to the hook portion 50 in the range of the gap 503 between the upper support portion 500 and the lower support portion 501. As a result, if the size of the gap 503 is set within a range in which the hook portion 50 is displaced corresponding to a range in which the tilt pan 32 tilts, the tilt pan 32 can follow the tilting operation and can be held without falling off. can do.

  Further, between the upper support portion 500 and the lower support portion 501, an opening portion 502 that can attach and detach the hook portion 50 to the stationary lot portion 34 is provided. The gap 503 has a length that extends in a direction that intersects the opening direction of the opening 502 that allows the hook 50 to be attached to and detached from the stationary lot 34. According to this configuration, since the direction in which the hook part 50 can be attached and detached intersects the direction in which the hook part 50 can be relatively displaced, the hook part 50 can be relatively displaced so that the hook part 50 is not easily detached from the stationary lot part 34. it can. Therefore, it is possible to provide a holding structure in which the hook portion 50 is unlikely to fall off the stationary lot portion 34 with respect to the tilt pan 32 tilting.

  Further, the blower 4 is provided integrally with the tilt pan 32 via the bracket 5 in front of the stationary lot portion 34 and the seat wire 33. According to this configuration, for example, even when the seat wire 33 is bent and deformed, the blower device 4 is located in front of the stationary lot portion 34 and the like, so that a device in which the seat wire 33 hardly interferes with the blower device 4 can be provided. Therefore, it is possible to install the blower 4 that is relatively unaffected by the deformation of the seat wire 33 between the tilt pan 32 and the floor surface 6 where a space can be secured.

(Second Embodiment)
In 2nd Embodiment, the bracket 105 which is the other form of 1st Embodiment is demonstrated with reference to FIG. Components having the same reference numerals as those in the drawings according to the first embodiment and other configurations not described in the second embodiment are the same as those in the first embodiment and have the same effects. Hereinafter, differences from the first embodiment will be described.

  As shown in FIG. 6, the bracket 105 further includes a throttle portion that includes the above-described relative displacement means and narrows the open length of the open portion 1502 to be smaller than the outer diameter of the stationary lot portion 34. The narrowed portion includes an upper retaining portion 1500a extending from the upper support portion 1500 and a lower retaining portion 1501a extending from the lower support portion 1501 so as to reduce the open length of the opening portion 1502, for example, the vertical length. And comprising.

  Each of the upper retaining portion 1500a and the lower retaining portion 1501a is elastically deformed so that an interval between both is increased when an external force of a certain level or more is applied. When an external force exceeding a certain level is not applied, both retaining portions are not elastically deformed, and the distance between them is smaller than the outer diameter of the stationary lot portion 34. Both retaining portions are formed so as to have a hardness against bending to such an extent that they are not elastically deformed by an external force acting on the throttle portion during the tilting of the tilt pan 32. The bending hardness of both retaining portions can be set by adjusting the plate thickness dimension and the length dimension.

  For example, when the stationary lot portion 34 is held inside the hook portion 150 as shown in FIG. 6, if the hook portion 150 is largely displaced diagonally upward toward the front with respect to the stationary lot portion 34, The lot part 34 pushes and widens the aperture part. Then, when the interval between the upper retaining portion 1500a and the lower retaining portion 1501a is increased and the distance is larger than the outer diameter of the stationary lot portion 34, the hook portion 150 is detached from the stationary lot portion 34. At this time, the bracket 105 is fixed to the tilt pan 32 on the front side, but the holding force by the stationary lot portion 34 is lost on the rear side, and the bracket 105 is supported only by the tilt pan 32 and is in an unstable state.

  According to the bracket 105 of the second embodiment, even if an external force acts in a direction away from the stationary lot portion 34, the stationary lot portion 34 with respect to the hook portion 150 with respect to the hook portion 150 by the restricting portion if the external force does not elastically deform. The relative displacement of the can be suppressed. For example, in the tilting operation of the tilt pan 32, it is possible to suppress the hook portion 150 from dropping from the stationary lot portion 34.
