[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-123971 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-93525 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in a configuration in which a slide lever such as an operating lever is disposed in a recess formed in a cushion pad, as in the configuration described in Patent Document 1, it is desirable to be able to reduce the gap between the slide lever and the cushion pad from the perspective of the design of the vehicle seat, but this point is not taken into consideration in the configuration described in Patent Document 1. Also, in the configuration described in Patent Document 2, an opening is formed between the towel bar and the cushion pad, which is thought to lead to a decrease in the design of the vehicle seat.

[0005] In consideration of the above, an object of the present invention is to provide a vehicle seat that can suppress deterioration in design. [Means for solving the problem]

[0006] The vehicle seat of the first embodiment comprises a cushion pad that forms part of a seat cushion that supports the buttocks of a seated occupant from below the seat, and has a recess that is open on the lower side, and a slide lever, part of which is positioned within the recess and which, when operated in the up-and-down direction of the seat, allows the seat cushion to slide in the fore-and-aft direction of the seat, and is configured so that the portion of the slide lever that is positioned within the recess is operated in the up-and-down direction of the seat, with the portion of the slide lever above the seat and the edge of the recess always overlapping in the fore-and-aft direction of the seat.

[0007] In the vehicle seat of the first aspect, a portion of the slide lever is disposed within a recess formed in the cushion pad. When the portion of the slide lever disposed within the recess is operated in the seat up-down direction, the seat cushion is allowed to slide in the seat front-rear direction. Here, when the portion of the slide lever disposed within the recess is operated in the seat up-down direction, the portion of the slide lever above the seat and the edge of the recess are always overlapped in the seat front-rear direction. This prevents a gap from being formed in the seat up-down direction between the portion of the slide lever above the seat and the edge of the recess. As a result, it is possible to prevent a degradation in the design of the vehicle seat due to the formation of such a gap.

[0008] The second embodiment of the vehicle seat is the vehicle seat of the first embodiment, wherein a towel bar is provided on the seat lower side of the cushion pad, the towel bar having an operated portion extending axially in the seat width direction, and displacement of the operated portion allows the seat cushion to slide in the fore-and-aft direction of the seat, and the slide lever is configured to include a towel bar engagement portion that engages with the operated portion and an occupant operating portion that is operated by a seated occupant, and the operated portion is displaced when the occupant operating portion is operated in the up-and-down direction of the seat with the upper seat side portion of the occupant operating portion and the edge of the recess portion always overlapping in the fore-and-aft direction of the seat.

[0009] In the vehicle seat of the second aspect, when the occupant operating portion of the slide lever is operated in the seat up-down direction, the operated portion of the towel bar is displaced. This allows the seat cushion to slide in the seat front-rear direction. In this way, in the vehicle seat of the second aspect, the towel bar can be displaced by operating the slide lever. Here, when the occupant operating portion of the slide lever is operated in the seat up-down direction, the portion of the occupant operating portion above the seat and the edge of the recess are always overlapped in the seat front-rear direction. This prevents a gap from being formed in the seat up-down direction between the portion of the occupant operating portion above the seat and the edge of the recess. As a result, it is possible to prevent a degradation in the design of the vehicle seat due to the formation of such a gap.

[0010] The vehicle seat of the third aspect is the vehicle seat of the second aspect, in which, when viewed from the seat width direction, the surface on the edge side of the recess in the occupant operating part has a curved cylindrical shape that follows the movement trajectory of the operated part.

[0011] In the vehicle seat of the third aspect, when viewed in the seat width direction, the surface of the recessed portion of the occupant operating portion on the edge side is curved like a cylindrical surface that follows the movement path of the operated portion. This configuration, compared to a configuration in which the surface of the recessed portion on the edge side of the occupant operating portion has a different shape from the above-mentioned shape, reduces changes in the clearance between the surface of the recessed portion on the occupant operating portion on the edge side and the edge of the recess when the occupant operating portion of the slide lever is operated in the seat up-down direction. As a result, it is possible to further reduce the formation of a gap in the seat up-down direction between the seat upper portion of the occupant operating portion and the edge of the recess.

[0012] The vehicle seat of the fourth aspect is configured such that, in the vehicle seat of the first aspect, both side portions of the slide lever in the seat width direction and the edge portion of the recess portion always overlap in the front-to-rear direction of the seat, and the portion of the slide lever that is located within the recess portion is operated in the seat up-and-down direction.

[0013] In the vehicle seat of the fourth aspect, when the portion of the slide lever disposed within the recess is operated in the seat up-down direction, both side portions of the slide lever in the seat width direction and the edge portions of the recess are always overlapped in the seat front-rear direction. This prevents the formation of gaps in the seat width direction between both side portions of the slide lever in the seat width direction and the edge portions of the recess. As a result, it is possible to prevent the formation of such gaps from deteriorating the design of the vehicle seat. [Effects of the Invention]

[0014] The vehicle seat according to the present invention has the excellent effect of being able to suppress deterioration in design. [Brief explanation of the drawings]

[0016] A vehicle seat 10 according to an embodiment of the present invention will be described using Figures 1 and 2. In the figures, the arrow FR indicates the front side of the seat, the arrow UP indicates the upper side of the seat, the arrow RH indicates the right side in the seat width direction, and the arrow LH indicates the left side in the seat width direction. In the following description, unless otherwise specified, when referring to front-rear, up-down, and left-right directions, these refer to front-rear in the front-rear direction of the seat, up-down in the seat up-down direction, and left-right in the seat width direction.

[0017] 1, a vehicle seat 10 of this embodiment is a type of vehicle seat that allows two occupants to be seated side by side in the left-right direction. The vehicle seat 10 includes a seat cushion 12 that supports the buttocks of the seated occupant from below, a seat back 13 that supports the back of the seated occupant from the rear, and a headrest 15 that supports the head of the seated occupant from the rear. The vehicle seat 10 also includes a slide rail 14 that supports the seat cushion 12 so that it can slide in the front-rear direction, and a release unit 16 that releases the lock on the slide rail 14.

[0018] As shown in FIG. 2 , the seat cushion 12 includes a cushion frame 18 that forms the framework of the seat cushion 12 and a cushion pad 20 attached to the cushion frame 18. The cushion frame 18 includes a pair of left and right side frame portions 22 that are spaced apart in the left-right direction and extend in the front-rear direction. The cushion frame 18 also includes a front frame portion 24 that connects front portions of the pair of left and right side frame portions 22 in the left-right direction. The front frame portion 24 is formed in a cylindrical shape with its axial direction extending in the left-right direction. A bracket 26, to which an end 52A of an outer tube 52 of a cable 50 (described later) is attached, is fixed by welding or the like to a middle portion of the front frame portion 24 in the left-right direction. The cushion pad 20 is attached to the cushion frame 18 from above. The cushion pad 20 includes a main portion 20A that extends in the front-rear and left-right directions and a front extension portion 20B that extends downward from the front end of the main portion 20A and slopes forward. 1 and 2, a recess 21 having an open lower side is formed in the center in the left-right direction of the lower portion of the front extension 20B. When viewed from the front side, the upper edge 21A, the right edge 21B, and the left edge 21C of this recess 21 have a U-shape having an open lower side. The surface of the cushion pad 20 facing the seated occupant is covered with a trim (not shown).

[0019] 2, the bracket 26 is formed, for example, by pressing a steel plate material. The bracket 26 includes a fixed plate portion 28 extending in the left-right direction as its thickness direction, and a flange portion 30 that bends and extends to the left from the range from the upper end to the front end of the fixed plate portion 28. The fixed plate portion 28 is fixed to the front frame portion 24 by welding.

[0020] As shown in FIGS. 1 and 2 , the release portion 16 is configured to be released by operating the towel bar 56 via a first slide lever 48 or a second slide lever 49 serving as slide levers, thereby unlocking the slide of the slide rail 14. The first slide lever 48, which will be described in detail later, is provided below the center in the left-right direction of the front end of the seat cushion 12. The second slide lever 49 is provided, for example, at the upper end of the seat back 13. The second slide lever 49 and the release portion 16 (towel bar 56) are connected via a cable 50. The cable 50 includes a cylindrical outer tube 52 and a cable main 54 inserted into the outer tube 52. One end 52A of the outer tube 52 is engaged with the flange portion 30 of the bracket 26. One end of the cable main 54 is connected to the release portion 16 (towel bar 56), and the other end of the cable main 54 is connected to the second slide lever 49.

[0021] Next, the detailed configuration of the towel bar 56 and the first slide lever 48 will be described.

[0022] 2, towel bar 56 is formed, for example, by bending a steel rod, and is hung between left and right slide rails 14. This towel bar 56 has an operated portion 56A that extends with its axis aligned with the seat width direction. By displacing this operated portion 56A upward, release portion 16 connected to towel bar 56 enters a released state.

[0023] The first slide lever 48 is formed using a resin material, for example. The first slide lever 48 includes a towel bar engagement portion 58 that engages with the operated portion 56A of the towel bar 56, an occupant operation portion 60 that is operated by the seated occupant, and a connection portion 62 that connects the towel bar engagement portion 58 and the occupant operation portion 60. The towel bar engagement portion 58 includes a first engagement portion 58A that is in vertical contact with the operated portion 56A below the operated portion 56A. The towel bar engagement portion 58 also includes a second engagement portion 58B that protrudes upward from the front end of the first engagement portion 58A and is in front-to-rear contact with the operated portion 56A on the front side of the operated portion 56A. The connection portion 62 protrudes forward from an upper portion of the second engagement portion 58B. The occupant operating unit 60 includes an occupant operating unit upper portion 60A constituting an upper portion of the occupant operating unit 60, and an occupant operating unit lower portion 60B constituting a lower portion of the occupant operating unit 60. The occupant operating unit upper portion 60A is formed in a rectangular shape when viewed from the front, and is gently inclined forward as it approaches the bottom. The center portion in the left-right and up-down directions of the rear surface of the occupant operating unit upper portion 60A is connected to the front end of the connecting portion 62. Here, FIG. 2 shows the first slide lever 48 in a state before it is operated by the seated occupant. Before the first slide lever 48 is operated by the seated occupant, the upper end portion 60A1 of the occupant operating unit upper portion 60A overlaps with the upper edge portion 21A of the recess portion 21 in the front-rear direction. Furthermore, the front surface of the occupant operating portion upper portion 60A (the surface facing the upper edge 21A of the recess 21) is a curved surface 60A2 that is cylindrically curved along the movement path of the operated portion 56A when viewed in the seat width direction. This curved surface 60A2 is disposed close to the upper edge 21A of the recess 21 in the front-rear direction. The occupant operating portion lower portion 60B protrudes forward from the lower end of the occupant operating portion upper portion 60A and is gently inclined downward as it extends forward. Before the first slide lever 48 is operated by the seated occupant, the occupant operating portion lower portion 60B and a portion of the occupant operating portion upper portion 60A are disposed inside the recess 21.Furthermore, when the occupant operating unit 60 is viewed from the front, the clearance between the right end of the occupant operating unit 60 and the right edge 21B of the recess 21 is the same as the clearance between the left end of the occupant operating unit 60 and the left edge 21C of the recess 21.

[0024] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0025] 1 and 2, in the vehicle seat 10 of this embodiment, when a seated occupant places their hand on the lower portion 60B of the occupant operation portion of the first slide lever 48 and pulls the occupant operation portion 60 upward, the first slide lever 48 is displaced upward together with the operated portion 56A of the towel bar 56. This causes the release portion 16 to enter a released state, allowing the seat cushion 12 to slide in the front-rear direction. In this way, in the vehicle seat 10 of this embodiment, the towel bar 56 can be displaced by operating the first slide lever 48.

[0026] Here, when the occupant operation unit 60 of the first slide lever 48 is operated in the seat up-down direction, the occupant operation unit upper portion 60A of the occupant operation unit 60 and the upper edge portion 21A of the recessed portion 21 are always overlapped in the front-rear direction. This prevents a gap from being formed in the seat up-down direction between the occupant operation unit upper portion 60A and the upper edge portion 21A of the recessed portion 21. As a result, it is possible to prevent a deterioration in the design of the vehicle seat 10 due to the formation of such a gap.

[0027] Furthermore, in the vehicle seat 10 of this embodiment, the front surface of the occupant operation unit upper portion 60A is a curved surface 60A2 that is curved like a cylindrical surface along the movement path of the operated portion 56A when viewed in the seat width direction. In this configuration, compared to a configuration in which the front surface of the occupant operation unit upper portion 60A has a shape different from the above-mentioned shape, when the occupant operation unit 60 of the first slide lever 48 is operated in the up and down direction, change in the clearance between the front surface of the occupant operation unit upper portion 60A and the upper edge 21A of the recess 21 is suppressed. As a result, it is possible to further suppress the formation of a gap in the up and down direction between the occupant operation unit upper portion 60A and the upper edge 21A of the recess 21.

[0028] In the vehicle seat 10 of this embodiment, the front surface of the occupant operation portion upper portion 60A is the curved surface 60A2, but the present invention is not limited to this. Whether or not the front surface of the occupant operation portion upper portion 60A is the curved surface 60A2 can be determined appropriately in consideration of the design of the first slide lever 48, etc.

[0029] In addition, in the vehicle seat 10 of this embodiment, an example has been described in which the towel bar 56 can be displaced by operating the first slide lever 48, but the present invention is not limited to this. For example, the first slide lever 48 and the release portion 16 may be directly connected to each other.

[0030] Furthermore, in the present embodiment, an example has been described in which the occupant operation portion upper portion 60A of the occupant operation portion 60 and the upper edge portion 21A of the recessed portion 21 are always overlapped in the front-rear direction, but the present invention is not limited thereto. For example, as in the first slide lever 48 shown in FIG. 3 , the occupant operation portion upper portion 60A of the occupant operation portion 60 and the upper edge portion 21A of the recessed portion 21 can be always overlapped in the front-rear direction, and the left and right side portions 60C, 60D of the occupant operation portion 60 can be always overlapped in the front-rear direction with the right edge portion 21B and the left edge portion 21A of the recessed portion 21. This configuration prevents gaps from being formed in the seat width direction between the left and right side portions 60C, 60D of the occupant operation portion 60 and the right edge portion 21B and the left edge portion 21A of the recessed portion 21. As a result, it is possible to prevent the design of the vehicle seat 10 from being impaired by the formation of such gaps.

[0031] The above describes one embodiment of the present invention, but the present invention is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope of the gist of the present invention. [Explanation of symbols]
