Description

[Technical Field]

[0001] The present invention relates to a vehicle seat. [Background technology]

[0002] BACKGROUND ART A structure in which a seat back cover that covers the rear surface of a seat back of a vehicle seat extends to the lower side of a seat cushion has been conventionally known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-77715 Summary of the Invention [Problem to be solved by the invention]

[0004] However, some cover members that cover the underside of the seat cushion loosen due to their own weight, causing their outer ends in the seat width direction to become open. That is, some cover members can create a large gap in the vertical direction between the outer ends of the seat cushion and the cover member in the seat width direction. When such a gap is formed, foreign objects can easily enter through the gap.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicle seat in which the outer end in the seat width direction is unlikely to open even if the cover member covering the lower side of the seat cushion becomes loose due to its own weight. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a first aspect of the vehicle seat according to the present invention comprises a seat cushion and a cover member that covers the seat underside of the seat cushion, and a biasing member is provided at the seat width direction outer end of the cover member to bias the seat width direction outer end toward the seat cushion.

[0007] According to the first aspect of the invention, a biasing member is provided at the outer end of the cover member covering the underside of the seat cushion in the seat width direction to bias the outer end toward the seat cushion. Therefore, even if the cover member sags due to its own weight, the outer end is unlikely to be released.

[0008] Furthermore, a second aspect of the vehicle seat according to the present invention is the vehicle seat of the first aspect, wherein the biasing member is composed of a band-shaped member that extends in the fore-and-aft direction and is inserted alternately from the lower side and the upper side of the seat into a plurality of slit portions formed at the outer end of the cover member in the seat width direction.

[0009] According to the second aspect of the invention, the biasing member is a strip-shaped member that is inserted alternately from the lower side and the upper side of the seat into a plurality of slits formed in the outer end of the cover member in the seat width direction, extending in the front-rear direction, thereby effectively biasing almost the entire outer end of the cover member in the seat width direction toward the seat cushion.

[0010] Furthermore, a third aspect of the vehicle seat according to the present invention is the vehicle seat of the second aspect, wherein the rear end of the belt-shaped member is attached to the rear end of the cover member and the front end is engaged with the front end of the seat cushion frame of the seat cushion.

[0011] According to the third aspect of the invention, the rear end of the belt-shaped member is attached to the rear end of the cover member, and the front end of the belt-shaped member is engaged with the front end of the seat cushion frame of the seat cushion, so that the belt-shaped member can be easily attached to the seat cushion.

[0012] Furthermore, a fourth aspect of the vehicle seat according to the present invention is a vehicle seat according to the third aspect, wherein a locking member is provided at the front end of the cover member to be locked to the front end of the seat cushion frame of the seat cushion, and the belt-shaped member has a length that is shorter than the length from the rear end of the cover member to the tip of the locking member.

[0013] According to the fourth aspect of the invention, a locking member is provided at the front end of the cover member to be locked to the front end of the seat cushion frame of the seat cushion, and the length of the band-shaped member is shorter than the length from the rear end of the cover member to the tip of the locking member. Therefore, even if the cover member sags due to its own weight, a gap is even less likely to occur between the outer end of the seat cushion in the seat width direction and the outer end of the cover member in the seat width direction, and the gap is extremely reduced.

[0014] A vehicle seat according to a fifth aspect of the present invention is the vehicle seat according to any one of the second to fourth aspects, wherein the belt-shaped member is a rubber band.

[0015] According to the fifth aspect of the invention, the belt-shaped member is a rubber band, which makes it possible to configure the urging member more simply and inexpensively than when the belt-shaped member is not a rubber band.

[0016] In addition, a sixth aspect of the vehicle seat according to the present invention is a vehicle seat according to any one of the first to fifth aspects, in which a structure is provided below the seat cushion above the cover member.

[0017] According to the sixth aspect of the invention, a structure is provided under the seat cushion above the seat with respect to the cover member. Here, since the outer end of the cover member in the seat width direction is difficult to open, a gap is unlikely to occur between the outer end of the seat cushion in the seat width direction and the outer end of the cover member in the seat width direction, and foreign matter is unlikely to enter through the gap. Therefore, the structure is effectively protected by the cover member.

[0018] Furthermore, a seventh aspect of the vehicle seat according to the present invention is the vehicle seat of the sixth aspect, wherein the structure is an airflow generating device that generates an airflow on the seat cushion, and the cover member is breathable.

[0019] According to the seventh aspect of the invention, the structure is an airflow generating device that generates airflow toward the seat cushion. Therefore, the airflow generating device is effectively protected by the cover member. Furthermore, because the cover member is breathable, even if the gap between the outer end of the seat cushion in the seat width direction and the outer end of the cover member in the seat width direction is reduced, the function of the airflow generating device is not affected. [Effects of the Invention]

[0020] As described above, according to the present invention, even if the cover member covering the lower side of the seat cushion becomes loose due to its own weight, the outer end portion in the seat width direction is less likely to be released. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For convenience of explanation, the arrow UP shown in each drawing indicates the upward direction of the vehicle seat, the arrow FR indicates the forward direction of the vehicle seat, the arrow RH indicates the rightward direction of the vehicle seat, and the arrow LH indicates the leftward direction of the vehicle seat. Furthermore, in the following description, when the up / down, front / rear, and left / right directions are mentioned unless otherwise specified, they refer to the up / down, front / rear, and left / right directions of the vehicle seat. Furthermore, the left / right direction is synonymous with the seat width direction.

[0023] As shown in FIG. 1, the vehicle seat 10 according to this embodiment includes a seat cushion 12 on which an occupant (not shown) sits (supporting the occupant's buttocks and thighs), and a seat back 14 that is provided on the rear side of the seat cushion 12 and can be tilted in the front-rear direction with the seat width direction as its axial direction, and that supports the occupant's back.

[0024] At least the seat cushion 12 of the vehicle seat 10 is breathable, and an airflow generating device 16 is provided below the seat cushion 12 as an example of a structure for air conditioning by blowing air from below the seat cushion 12 or by drawing air above the seat cushion 12. In other words, the vehicle seat 10 is an air-conditioned seat.

[0025] A storage tray 18 having a generally rectangular housing shape in plan view is provided below the seat cushion 12. The upper portions of both left and right ends of the storage tray 18 are suspended and supported by support members 17 that are generally U-shaped in side view and are attached to a seat cushion frame (not shown) of the seat cushion 12 so that they can slide in the front-rear direction. In other words, the storage tray 18 is configured to be manually pulled out from the lower side of the seat cushion 12 to the front side, and to be manually stored from the front side of the seat cushion 12 to the lower side.

[0026] The seat cushion 12 is also provided with a carpet 20 as a cover member that covers the lower side thereof. The carpet 20 is breathable, and its rear end is sewn to the lower end of the seat back cover 15 to be integrally attached thereto. As shown in Fig. 2, a pair of locking members 22 that are locked to the front end of the seat cushion frame of the seat cushion 12 are provided on the left and right sides of the front end of the carpet 20 at a predetermined interval in the seat width direction.

[0027] Each locking member 22 is composed of a band-shaped (approximately rectangular and flat in cross section) rubber band 22A of a predetermined width and length, the rear end of which is sewn to the underside of the front end of the carpet 20, and a metal or resin hook portion 22B attached integrally to the front end of the rubber band 22A. Each hook portion 22B is configured to be able to lock onto (hook onto) the front end of the seat cushion frame of the seat cushion 12 from below, and the carpet 20 is configured to cover and protect the airflow generating device 16 from below.

[0028] When the seat back 14 is tilted forward, the carpet 20, which is integral with the seat back cover 15, is pulled rearward and moves. Therefore, the length from the rear end of the carpet 20 to the front end (tip) of the rubber band 22A of the locking member 22 is set to a length that does not interfere with the forward tilt of the seat back 14, taking into account the stretch caused by elastic deformation of the rubber band 22A. Therefore, when the seat back 14 is in the driving position or a tilted-back position, the carpet 20 is not pulled rearward (is pushed forward), and is therefore configured to sag easily under its own weight.

[0029] 2, biasing members 24 are provided at the outer end 20A of the carpet 20 in the seat width direction to bias the outer end 20A in the seat width direction toward the seat cushion 12. Each biasing member 24 is configured as a strip-shaped member 26 whose rear end is attached by sewing to the rear end of the outer end 20A of the carpet 20 in the seat width direction, and whose front end (hook portion 26B described later) is hooked to the front end of the seat cushion frame of the seat cushion 12.

[0030] Each belt-shaped member 26 is composed of a belt-shaped (flat, rectangular cross section) rubber band 26A with a predetermined width and length, and a metal or resin hook portion 26B integrally attached to the front end of the rubber band 26A. Each hook portion 26B is also configured to be able to be engaged (hooked) from below with the front end of the seat cushion frame of the seat cushion 12, and the length of the rubber band 26A of each belt-shaped member 26 is shorter than the length from the rear end (rear edge) of the carpet 20 to the front end (tip) of the rubber band 22A of the engaging member 22.

[0031] In addition, the rubber bands 26A of each belt-shaped member 26 are attached to the outer end 20A of the carpet 20 in the seat width direction by having their middle portions inserted alternately from the lower and upper sides of the carpet 20 into a plurality of slit portions 28 formed at a predetermined interval in the front-to-rear direction at the outer end 20A of the carpet 20 in the seat width direction, and extend in the front-to-rear direction.

[0032] Specifically, slits 28 extending a predetermined length in the left-right direction are formed in the seat width direction outer end 20A of the carpet 20, two in the front and two in the rear. That is, slits 28A and 28B are formed at the front of the seat width direction outer end 20A with a short gap in the front-to-rear direction, and slits 28C and 28D are formed at the rear of the seat width direction outer end 20A with a short gap in the front-to-rear direction. The gap between slits 28B and 28C is longer than the gap between slits 28A and 28B and the gap between slits 28C and 28D.

[0033] Therefore, the rubber band 26A, whose rear end is sewn and attached to the underside of the rear end of the seat width direction outer end 20A of the carpet 20, is inserted from below into one (rear) slit portion 28D at the rear of the seat width direction outer end 20A, and is inserted from above into the other (front) slit portion 28C at that rear portion, and further inserted from below into one (rear) slit portion 28B at the front of the seat width direction outer end 20A, and is inserted from above into the other (front) slit portion 28A at that front portion, so that its front end extends from the underside of the carpet 20 to protrude forward of the carpet 20.

[0034] Each strip-shaped member 26 attached to the seat width direction outer end 20A of the carpet 20 has its respective hook portion 26B engaged with the front end of the seat cushion frame of the seat cushion 12, thereby urging the seat width direction outer end 20A of the carpet 20 toward the seat cushion 12, more specifically, toward the underside of the seat cushion 12, as shown in Figure 3, thereby reducing the gap S1 that occurs between the seat width direction outer end 12A (the portion facing the seat width direction outer end 20A of the carpet 20 in the vertical direction) on the underside of the seat cushion 12 and the seat width direction outer end 20A of the carpet 20.

[0035] Next, the operation of the vehicle seat 10 according to this embodiment configured as described above will be described.

[0036] First, a carpet 30 according to a comparative example shown in Fig. 4 will be described. This carpet 30 does not have a belt-shaped member 26 as the biasing member 24. Therefore, as shown in Fig. 4, this carpet 30 sags due to its own weight, causing the outer end 30A in the seat width direction to open.

[0037] That is, a wide gap S2 is formed in the vertical direction between the outer end 12A in the seat width direction on the underside of the seat cushion 12 and the outer end 30A in the seat width direction of the carpet 30. When such a gap S2 is formed, foreign matter can easily enter through the gap S2, making it impossible to effectively protect the airflow generating device 16 and impairing the appearance of the vehicle seat.

[0038] 2 and 3, the carpet 20 according to this embodiment is provided with a belt-shaped member 26 at its outer end 20A in the seat width direction as a biasing member 24 for biasing the outer end 20A in the seat width direction toward the seat cushion 12. Therefore, even if the central portion of the carpet 20 in the seat width direction (the portion excluding the outer end 20A in the seat width direction) becomes loose due to its own weight, the outer end 20A in the seat width direction is unlikely to loosen or open.

[0039] That is, the biasing member 24 (strip-shaped member 26) can make it difficult for a gap S1 to occur between the seat width direction outer end 12A on the underside of the seat cushion 12 and the seat width direction outer end 20A of the carpet 20. In other words, it is possible to reduce the gap S1 that occurs between the seat width direction outer end 12A on the underside of the seat cushion 12 and the seat width direction outer end 20A of the carpet 20.

[0040] Therefore, foreign matter is less likely to enter through the gap S1 (entry of foreign matter can be suppressed or prevented), and the airflow generating device 16 provided below the seat cushion 12 can be effectively protected by the carpet 20. Furthermore, because the gap S1 can be reduced, the appearance of the vehicle seat 10 can be prevented from being impaired.

[0041] Note that even if the gap S1 generated between the seat width direction outer end 12A on the underside of the seat cushion 12 and the seat width direction outer end 20A of the carpet 20 is reduced, the carpet 20 is breathable, and therefore the function of the airflow generating device 16 is not affected. Furthermore, by reducing the gap S1, it is possible to suppress or prevent the seat width direction outer end 20A of the carpet 20 from getting caught on the slide rail 11 when the vehicle seat 10 is moved in the front-rear direction along the slide rail 11 (see FIGS. 3 and 4).

[0042] 2, the rubber bands 26A of each belt-shaped member 26 extend in the front-rear direction by being inserted alternately from the lower side and the upper side of the carpet 20 into a plurality of slits 28 formed in the outer end 20A of the carpet 20 in the seat width direction. Therefore, almost the entire outer end 20A of the carpet 20 in the seat width direction can be effectively biased toward the seat cushion 12.

[0043] Furthermore, the length of the rubber band 26A of each belt-shaped member 26 is shorter than the length from the rear end of the carpet 20 to the front end (tip) of the rubber band 22A of the locking member 22. Therefore, even if the center portion of the carpet 20 in the seat width direction (excluding the outer end portion 20A in the seat width direction) sags due to its own weight, it is possible to make it even less likely that a gap S1 will occur between the outer end portion 12A in the seat width direction on the underside of the seat cushion 12 and the outer end portion 20A in the seat width direction of the carpet 20, and it is possible to significantly reduce the gap S1.

[0044] The urging member 24 is formed of a belt-shaped member 26, and its rear end is attached by sewing to the rear end of the outer end 20A in the seat width direction of the carpet 20, and its front end (hook portion 26B) is attached by being hooked to the front end of the seat cushion frame of the seat cushion 12. Therefore, the urging member 24 (belt-shaped member 26) can be easily attached to the seat cushion 12. Moreover, because the belt-shaped member 26 is formed of the rubber band 26A, the urging member 24 can be formed more simply and inexpensively than when the belt-shaped member 26 is not formed of the rubber band 26A.

[0045] 1, even if a storage tray 18 is provided below the seat cushion 12, the carpet 20 is provided between the storage tray 18 and the airflow generator 16, which reduces or prevents problems such as damage to the airflow generator 16 caused by items stored inside the storage tray 18 when the storage tray 18 is taken out or put back in. In other words, the carpet 20 also functions as a partition member separating the storage tray 18 from the airflow generator 16, so that the airflow generator 16 can be effectively protected not only from foreign objects but also from items stored inside the storage tray 18.

[0046] Although the vehicle seat 10 according to this embodiment has been described above with reference to the drawings, the vehicle seat 10 according to this embodiment is not limited to the illustrated one, and the design can be appropriately modified within the scope of the gist of the present invention. For example, the structure is not limited to the airflow generating device 16, and may be an ECU, a harness, a connector, etc., although not shown.

[0047] Furthermore, the positions and number of the slits 28 formed in the outer end 20A of the carpet 20 in the sheet width direction are not limited to those shown in Fig. 2. Furthermore, the biasing member 24 is not limited to the belt-shaped member 26 (rubber band 26A) having a substantially rectangular flat cross section, but may be, for example, a string-shaped member (rubber string: not shown) having a substantially circular cross section.

[0048] Furthermore, the carpet 20 is not limited to being integrally attached to the lower end of the seat back cover 15, but may be configured to be provided separately from the seat back cover 15, or may be configured to be integrally attached to the front end of the seat cushion cover (not shown) and be attached by being engaged with the rear end of the seat cushion frame.
