Description

  The present invention relates to a sheet.

Among the seats, a seat having a lift-up mechanism that moves a vehicle seat body from a storage position in a passenger compartment to an entry / exit position outside the vehicle is known. The lift-up mechanism includes a leg portion, a front / rear slide portion, a rotation portion, an elevating portion, and an outer slide portion. Specifically, legs are provided on the floor, and front and rear slide parts are stacked on the legs from above. Further, the rotating part is overlapped on the front and rear slide part from above, and the elevating part is overlapped on the rotating part from above. Furthermore, an outer slide part is overlaid on the elevating part. A seat body is provided on the outer slide portion.
In this manner, the leg portion, the front / rear slide portion, the rotation portion, the lifting / lowering portion, and the outer slide portion are stacked in order from above. For this reason, the height dimension from the seat cushion upper surface of the seat body to the leg portion is increased.

  According to this seat, the rotating part is moved in the front-rear direction by the leg part, and the elevating part is rotated toward the opening part of the vehicle by the rotating part. Next, the seat body is moved from the opening portion toward the outside of the vehicle by the outer slide portion. Next, when the elevating part is moved from the opening part toward the outside of the vehicle, the seat main body is lowered to the boarding / exiting position by the elevating part (see, for example, Patent Document 1).

In addition, a driving motor is provided in the leg portion, the rotating portion, the elevating portion, and the outer slide portion. Each motor is connected to a control unit (ECU) by a wire harness. Each motor is controlled based on a signal from the control unit (see, for example, Patent Document 2).

JP 2013-56570 A Japanese Patent No. 4046113

  Here, the folding part of the movable cable cover of Patent Document 2 is folded up and down. Therefore, the height dimension of the folded portion is relatively large. For this reason, it is considered that the height dimension from the upper surface of the seat cushion of the seat body to the leg portion is increased.

  Therefore, the present invention provides a seat that can suppress the height dimension from the upper surface of the seat cushion to the leg portion.

  In order to solve the above-described problem, the invention described in claim 1 includes a leg portion (for example, the leg portion 35 of the embodiment) fixed to a floor (for example, the floor panel 16 of the embodiment), and the leg portion. A first slide part (for example, the front / rear slide part 36 of the embodiment) provided above the first slide part so as to be movable in the extending direction of the leg part, and disposed above the first slide part. A rotating part (for example, the rotating part 37 of the embodiment) provided rotatably on one slide part, an elevating part (for example, the elevating part 38 of the embodiment) provided on the rotating part, and an upper part of the elevating part A sheet body (for example, the sheet body 32 of the embodiment) connected via a second slide part (for example, the outer slide part 39 of the embodiment), and the sheet body is in a storage position (for example, the embodiment). Storage position P1) and boarding / exiting position (For example, the lift-up seat 20 according to the embodiment) that is movable between (for example, the boarding / exiting position P2 according to the embodiment) and attached to the rotating part and the lifting part, and accompanying the movement of the lifting part. Attached to the first movable cable cover (for example, the first movable cable cover 41 of the embodiment) for guiding the wire harness (for example, the wire harness 43 of the embodiment), the elevating part, and the second slide part. A second movable cable cover (for example, the second movable cable cover 42 of the embodiment) that guides the wire harness (for example, the wire harness 43 of the embodiment) as the second slide portion moves. The first movable cable cover and the second movable cable cover are folded back in the horizontal direction and have the same height. And it is provided on.

  Thus, the first movable cable cover and the second movable cable cover were folded back in the horizontal direction and provided to have the same height. Therefore, compared with the case where the first movable cable cover and the second movable cable cover are arranged so as to overlap each other, the thickness dimensions of the first movable cable cover and the second movable cable cover should be kept small. Can do. Thereby, the height dimension from the seat cushion upper surface of the seat body to the leg portion can be suppressed.

  According to a second aspect of the present invention, when the seat body moves to the boarding / alighting position, the second slide portion moves before the lifting portion, and the seat body moves to the retracted position. The elevating part is configured to move before the second slide part, and the second folded part (for example, the folded part 42c of the embodiment) in which the second movable cable cover is folded is the first movable part. The cable cover is disposed on the side of the getting-on / off position with respect to the first folded portion (for example, the folded portion 41c of the embodiment) where the cable cover is folded.

By the way, the 1st movable cable cover is attached to the rotation part and the raising / lowering part. A second movable cable cover is attached to the elevating part and the second slide part.
Here, when the seat body is moved from the room to the room, the second slide part moves ahead of the lifting part. On the other hand, when the seat main body is moved from the outdoor to the indoor, the elevating part is changed in advance of the second slide part.
Therefore, in claim 2, the folded portion of the second movable cable cover is disposed in front of the folded portion of the first movable cable cover. Therefore, when the seat is moved from the indoor to the outdoor, the folded portion of the second movable cable cover moves forward ahead of the folded portion of the first movable cable cover. Thereby, it can prevent that the folding | turning part of a 2nd movable cable cover interferes with the folding | turning part of a 1st movable cable cover.
On the other hand, when the seat is moved from the outdoor to the indoor, the folded portion of the first movable cable cover moves rearward before the folded portion of the second movable cable cover. Accordingly, it is possible to prevent the folded portion of the first movable cable cover from interfering with the folded portion of the second movable cable cover.

  According to a third aspect of the present invention, the rotation center of the rotating portion (for example, the rotation center 74 of the embodiment) is located on one side in the width direction of the sheet main body, and on the one side in the width direction of the sheet main body, A first movable cable cover and the second movable cable cover are provided.

  In this way, the rotation center of the rotating part is positioned on one side in the width direction of the sheet main body. Further, a first movable cable cover and a second movable cable cover were arranged on one side in the width direction of the seat body. Therefore, the space (space) which arrange | positions the structural member of a sheet | seat on the other side of the width direction of a sheet | seat main body is securable. Thereby, the freedom degree at the time of determining the arrangement | positioning location (layout) of the structural member of a sheet | seat can be raised.

  According to a fourth aspect of the present invention, the first movable cable cover and the second movable cable cover are formed in a J shape in plan view in a state where the seat body is stored in the storage position. Each of the first movable cable cover and the second movable cable cover is movably attached to each of the first movable cable cover and the second movable cable cover. The distance dimension is larger than the distance dimension from the one end part to the folded part.

Thus, the first movable cable cover and the second movable cable cover were folded back in a J shape at the folded portion. Moreover, each other end part was movably attached to each one end part of the first movable cable cover and the second movable cable cover. Furthermore, the distance dimension from the other end part to the folded part was made larger than the distance dimension from the one end part to the folded part. Therefore, the return | foldable area | region of a 1st movable cable cover and a 2nd movable cable cover can be ensured long.
Here, the 1st movable type cable cover is attached so that a wire harness may be guided with the movement of an raising / lowering part. Moreover, the 2nd movable cable cover is attached so that a wire harness may be guided with the movement of a 2nd slide part. Thereby, the movement amount of a raising / lowering part and a 2nd slide part is securable.

  The invention described in claim 5 is characterized in that the rotating portion is provided with a reinforcing portion (for example, the reinforcing portion 64 of the embodiment) on the other side in the width direction of the sheet main body.

  Here, a space (space) for arranging the constituent members of the sheet is secured on the other side in the width direction of the sheet main body. Therefore, a reinforcing part is provided on the other side in the width direction of the seat body using this space. Thereby, the rigidity of a sheet | seat can be improved with a reinforcement part.

  According to the sixth aspect of the present invention, a bearing (for example, the bearing 63 of the embodiment) that supports the lifting unit is provided in the rotating unit, and the reinforcing unit is a straight line (for example, connecting the rotation center and the bearing) , Arranged along a straight line 76) of the embodiment.

Here, a relatively large load such as a seat body is applied to the rotating portion and the bearing.
Accordingly, in claim 6, the reinforcing portion is arranged on a straight line connecting the rotation center of the rotating portion and the bearing on the other side in the width direction of the seat body. Thereby, a rotation part and a bearing can be reinforced with a reinforcement part. Thereby, the rigidity of the sheet can be increased.

  According to this invention, the first movable cable cover and the second movable cable cover are folded back in the horizontal direction so as to have the same height. Therefore, the thickness dimension of the first movable cable cover and the second movable cable cover can be kept small. Thereby, the height dimension from the seat cushion upper surface of the seat body to the leg portion can be suppressed.

  The rear elevating base 81 is attached with a screw nut 86. The screw nut 86 is rotatably connected to the screw 85. The screw 85 is connected to the lifting motor 84. The lift motor 84 is attached to the rear portion 37 a of the rotating portion 37. By rotating the screw 85 by the lifting motor 84, the rear lifting base 81 together with the screw nut 86 moves in the front-rear direction (arrow C direction) of the lifting unit 38.

The elevating motor 84 is arranged such that the axis 87 of the elevating motor 84 is orthogonal to the moving direction (arrow C direction) of the elevating unit 38. In other words, the axis 87 of the lifting motor 84 is arranged in the width direction of the lifting unit 38. Further, in the state where the lift-up seat 20 is stored (the state shown in FIG. 3), the elevating motor 84 is disposed on the rear side of the elevating unit 38 (that is, the other side in the moving direction of the elevating unit 38).
Therefore, a large space (space) 89 can be secured in the moving direction of the elevating unit 38 in the state where the lift-up seat 20 is stored. Thereby, the freedom degree at the time of determining the arrangement | positioning location (layout) of the structural member of the lift-up seat 20 can be raised.

Further, the rear elevating base 81 is connected to the link unit 83. The link unit 83 includes a left upper link 92, a left lower link 93, a right upper link 92, and a right lower link 93.
A rear end portion of the left upper link 92 and a rear end portion of the left lower link 93 are rotatably connected to the left end portion of the rear elevating base 81. The rear end portion of the right upper link 92 and the rear end portion of the right lower link 93 are rotatably connected to the right end portion of the rear elevating base 81. That is, the rear elevating base 81 is provided on the rear part 38 a of the elevating part 38.

  The rear elevating base 81 has a rear base central portion 81a that connects the left end portion and the right end portion. The rear base center portion 81a is formed flat and arranged horizontally. The rear base center portion 81a is disposed at a height position equivalent to the lower portion of the lifting motor 84 in a state where the lift-up seat 20 is stored (see FIG. 3). Therefore, the rear base center portion 81a is arranged in a state of being lowered downward toward the rotating portion 37 (specifically, the base portion 61). Further, the rear base center portion 81a is horizontally disposed along the upper portion of the rotating portion 37 (base portion 61) in a state where the lift-up seat 20 is stored.

As described above, the rear lifting base 81 is disposed along the upper portion of the rotating portion 37, so that the height dimension of the lifting portion 38 can be kept small. Therefore, the height dimension H1 from the upper surface of the seat cushion 33 to the leg portion 35 can be further reduced in the retracted position P1 of the lift-up seat 20. Therefore, the height position P3 of the upper surface of the seat cushion 33 is kept low.
That is, the lift-up seat 20 can be thinned at the storage position P1 of the lift-up seat 20.

  The front end of the left upper link 92 and the front end of the left lower link 93 are rotatably connected to the left end of the front lifting base 82. Further, the front end portion of the right upper link 92 and the front end portion of the right lower link 93 are rotatably connected to the right end portion of the front lifting base 82. That is, the front elevating base 82 is provided on the front portion 38b of the elevating unit 38 (one in the moving direction of the elevating unit 38).

That is, in the elevating unit 38, the rear elevating base 81 and the front elevating base 82 are connected by the link unit 83. The left lower link 93 is supported by a left bearing 63 so as to be movable in the front-rear direction of the seat body 32. Further, the right lower link 93 is supported by the right bearing 63 so as to be movable in the front-rear direction of the seat body 32.
In this state, the elevating unit 38 can be moved in the front-rear direction of the seat body 32 as indicated by the arrow C by rotating the screw 85 by the elevating motor 84.
That is, the lifting motor 84 is a power device that moves the lifting unit 38 in the direction of arrow C.

The front elevating base 82 has a front base central portion 82a that connects the left end portion and the right end portion. The front base central portion 82a is formed flat and is disposed horizontally.
The front base central portion 82a is in a state where the lift-up seat 20 is stored.
It is arranged in front of the base part 61. That is, the base portion 61 and the front base center portion 82 a are arranged side by side in the front-rear direction of the seat body 32. Further, the base portion 61 and the front base center portion 82a are arranged so as not to overlap in the vertical direction (see also FIG. 2).

In other words, the base portion 61 and the front base center portion 82a are arranged substantially horizontally (that is, at an equivalent height). Therefore, the front base center portion 82a (that is, the elevating unit 38) can be lowered to the rotating unit 37 side.
Therefore, the height dimension H <b> 1 from the upper surface of the seat cushion 33 to the leg portion 35 is further reduced at the retracted position P <b> 1 of the lift-up seat 20. Therefore, the height position P3 of the upper surface of the seat cushion 33 is further suppressed.
That is, the lift-up seat 20 can be further reduced in thickness at the storage position P1 of the lift-up seat 20.

As shown in FIG. 2, in the vehicle 10, the raised portion 28 of the floor panel 16 on the lower side of the lift-up seat 20 is bulged upward. The fuel tank 18 is disposed in a space 29 below the raised portion 28.
On the other hand, in the lift-up seat 20, the height dimension H <b> 1 from the upper surface of the seat cushion 33 to the leg portion 35 is kept small at the storage position P <b> 1. Therefore, the height position P3 of the upper surface of the seat cushion 33 is kept low. Thereby, in the state where the lift-up seat 20 is attached to the raised portion 28 of the vehicle 10, the height position P3 of the upper surface of the seat cushion 33 is kept low.
Thus, when the seat body 32 is moved from the storage position P1 in the passenger compartment 12 to the entrance / exit position P2 outside the passenger compartment 12 (see FIG. 8), the seat body 32 can be smoothly moved to the entrance / exit position P2. . That is, the lift-up seat 20 can be applied to the vehicle 10 on which the raised portion 28 is formed.

  In the state in which the lift-up seat 20 is stored, a second space 95 (see also FIG. 3) is secured between the front edge 61a of the base portion 61 and the rear edge 82b of the front base center portion 82a. The second space 95 will be described in detail later. An outer slide part 39 is supported by the elevating part 38.
