[0010] Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In each figure, "front and rear" indicates the vehicle front-rear direction, "left and right" indicates the vehicle width direction (left-right direction), and "up and down" indicates the vehicle up-down direction (vertical up-down direction).

[0011] As shown in FIG. 1, a vehicle 10 to which a seating member structure according to a first embodiment of the present invention is applied is constituted by an automobile having a secondary power source used for running drive and / or a detachable battery portable power source, for example, an electric vehicle or a hybrid vehicle.

[0012] As shown in FIG. 1, a seating member (vehicle seat) 14 on which a front passenger 12 sits is disposed in the front of the vehicle interior of the vehicle 10. This seating member 14 includes a seat cushion 16 on which the front passenger 12 sits and a seat back 18 that stands behind the seat cushion 16 and supports the back of the seated front passenger 12. The seat cushion 16 has a seating surface portion 20 that holds the buttocks of the front passenger 12. The seat back 18 has a front back surface portion 22 that holds the back of the front passenger 12.

[0013] In a side view of the vehicle, a portable battery 26 having a battery case 24 for storing a battery pack is disposed inside the seat back 18 of the seating member 14 and behind the front back surface portion 22 in the vehicle rear direction. This portable battery 26 is detachably provided from the side of the vehicle (vehicle width direction).

[0014] Specifically, a gap portion 28 is provided at a portion above the seating surface portion 20 and behind the vehicle of the front back surface portion 22 of the seating member 14 in the front of the vehicle interior, and a portable battery 26 having a battery case 24 is detachably mounted in this gap portion 28 from the vehicle width direction.

[0015] In the present embodiment, by disposing the portable battery 26 at a portion behind the vehicle of the front back surface portion 22 of the seating member 14 in the front of the vehicle interior, it is possible to provide a region (mounting space) capable of storing the portable battery 26 without reducing the effective space in the vehicle interior.

[0016] Also, as a comparative example with this embodiment, in the case of a secondary power source of a type fixed to, for example, the floor portion of a vehicle, which is in a region below the vehicle seat, measures are required for the workability (the working posture of an operator) when detaching and attaching the portable battery 26 from the floor portion. In this embodiment, if it is at a position above the seat surface portion 20 behind the vehicle of the front-back surface portion 22 of the seating member 14, since it is located above the vehicle as compared with the case where it is fixed to the floor portion of the vehicle 10, the amount of bending of the operator's waist when performing the replacement work can be reduced (compare and refer to operator A and operator B in FIG. 5 described later).

[0017] Next, vehicles to which the seating member structure according to the second embodiment of the present invention is applied are shown in FIGS. 2 to 5. Note that the same reference numerals are given to the same components as those in the first embodiment shown in FIG. 1, and the detailed description thereof is omitted.

[0018] As shown in FIG. 2, in this embodiment, in the front of the vehicle interior of the vehicle 10a, there are a front passenger 12 who sits on the front side of the vehicle of the seating member 30 and a rear passenger 32 who sits on the rear side of the vehicle of the seating member 30. The front passenger 12 and the rear passenger 32 are arranged to sit back to back with the seating member 30 in between in the vehicle front-rear direction.

[0019] In this embodiment, the seating member 30 includes a front seat cushion 34 on which the front passenger 12 sits, a rear seat cushion 36 on which the rear passenger 32 sits, and a seat back 38 that stands between the front seat cushion 34 and the rear seat cushion 36 and supports the backs of the front passenger 12 and the rear passenger 32, respectively. In this embodiment, the "front seating member" is constituted by the front seat cushion 34 and the seat back 38, and the "rear seating member" is constituted by the rear seat cushion 36 and the seat back 38.

[0020] The front seat cushion 34 has a front seat surface portion 40 that holds the buttocks of the front passenger 12. The rear seat cushion 36 has a rear seat surface portion 42 that holds the buttocks of the rear passenger 32.

In a side view of the vehicle, the rear back surface portion 46 is inclined rearward of the vehicle from above the vehicle toward below the vehicle. A gap portion 48 that is recessed along the vehicle width direction is provided between the front back surface portion 44 and the rear back surface portion 46 of the seat back 38. This gap portion 48 is configured in a substantially trapezoidal shape in a side view of the vehicle. A portable battery 26 including a battery case 24 in which a battery pack is stored is disposed in the region (space) of this gap portion 48. Although detailed illustration is omitted, the battery case 24 has, for example, a rectangular parallelepiped shape that is long in the vehicle width direction and is provided with a handle or the like.

[0022] As shown in FIG. 4, the vehicle 10a has a front opening (opening) 52 and a rear opening 54 through which the front passenger 12 and the rear passenger 32 respectively get on and off from the side of the vehicle with the center pillar 50 therebetween. The portable battery 26 is disposed, for example, so as to be accessible from the vehicle width direction when the front opening 52 is in an open state (front door open state). The center pillar 50 is located between the front opening 52 and the rear opening 54.

[0023] The portable battery 26 is disposed at a position that does not overlap the center pillar 50 in the vehicle width direction. In the present embodiment, as shown in FIG. 4, the portable battery 26 is disposed so as to be located forward of the vehicle relative to the center pillar 50, but the present invention is not limited to this, and the portable battery 26 may be disposed so as to be located rearward of the vehicle relative to the center pillar 50.

[0024] As shown in FIG. 2, in a side view of the vehicle, the portable battery 26 is arranged to be located above the vehicle relative to the front seat surface portion 40 and the rear seat surface portion 42. In the present embodiment, in a side view of the vehicle, the portable battery 26 is arranged to be located above both the front seat surface portion 40 and the rear seat surface portion 42, but the present invention is not limited thereto. The portable battery 26 may be arranged, for example, to be located above at least one of the front seat surface portion 40 and the rear seat surface portion 42.

[0025] At the entrance portion of the gap portion 48 of the vehicle 10, a partition member 56 that partitions the portable battery 26 and the passenger compartment space of the vehicle 10 is provided (see the two-dot chain line in FIG. 3). This partition member 56 has a substantially trapezoidal shape in a side view of the vehicle and is arranged on the inner side in the vehicle width direction than the vehicle width direction end portion 58 (see FIG. 3) of the seating member 30. Specifically, it is arranged on the inner side in the vehicle width direction by the dimension of the arrow shown in FIG. 3. The partition member 56 includes a recess (battery installation portion) for installing the portable battery 26. Further, in the gap portion 48 of the vehicle 10, the partition member 56 is provided with a charging device 60 (for example, a charging port from a household outlet) for the portable battery 26 (see FIG. 3).

[0026] The vehicle 10a to which the seating member structure according to the present embodiment is applied is basically configured as described above, and the operation and effect thereof will be described next.

[0027] In the present embodiment, the seating member 30 has a front back surface portion 44 that holds the back surface of the front occupant 12 and a rear back surface portion 46 that holds the back surface of the rear occupant 32. A gap portion 48 is provided between the front back surface portion 44 and the rear back surface portion 46, and a portable battery 26 is arranged in the region of this gap portion 48 (inside the gap portion 48).

[0028] According to this embodiment, regarding the seating member 30 on which the front passenger 12 and the rear passenger 32 sit back to back with each other, a gap 48 is provided between the front back surface portion 44 and the rear back surface portion 46, and the portable battery 26 is arranged in the region of this gap 48, so that an effective space in the vehicle interior is not reduced, and a region (mounting space) capable of accommodating the portable battery 26 can be provided.

[0029] In this embodiment, the vehicle 10a has a front opening 52 and a rear opening 54 through which the front passenger 12 and the rear passenger 32 respectively get on and off from the side of the vehicle with the center pillar 50 in between (see FIG. 4). In a side view of the vehicle, the portable battery 26 is arranged so as to be accessible from the vehicle width direction, for example, when the front opening 52 is in an open state.

[0030] According to this embodiment, for example, when the front opening 52 is in an open state (front door open state), the portable battery 26 is arranged so as to be accessible from the vehicle width direction, so that interference with the vehicle 10a (for example, the center pillar 50) can be preferably avoided during the attachment and detachment operation of the portable battery by the operator.

[0031] Further, the portable battery 26 is arranged at a position that does not overlap with the center pillar 50 in the vehicle width direction, so that the workability during the attachment and detachment operation can be improved. In a vehicle without a center pillar, the degree of freedom in arranging the portable battery 26 is further improved. For example, a double-hinged vehicle (a vehicle having a skeleton corresponding to a center pillar on the door side), a large sliding door type vehicle that opens and closes from the front of the vehicle to the rear of the vehicle, etc. are applicable.

[0032] In this embodiment, the seating member 30 has a front seat surface portion 40 that holds the buttocks of the front passenger 12 and a rear seat surface portion 42 that holds the buttocks of the rear passenger 32. In a side view of the vehicle, the portable battery 26 is arranged so as to be located above the vehicle relative to the front seat surface portion 40 and the rear seat surface portion 42.

[0033] According to the present embodiment, by disposing the portable battery 26 above the vehicle rather than on the front seat surface portion 40 and the rear seat surface portion 42, for example, even when the vehicle is in a flooded situation, the portable battery 26 can be protected from being flooded. Further, as shown in FIG. 5, in the present embodiment, by disposing the portable battery 26 above the vehicle rather than on the front seat surface portion 40 and the rear seat surface portion 42, when detaching and attaching the heavy portable battery 26, operator A does not need to bend his / her waist as compared with the conventional case, and the working posture of operator A can be improved. Thereby, the burden on the waist of operator A can be reduced. On the other hand, for example, if the secondary power source P (see the two-dot chain line in FIG. 5) is disposed at a location close to the floor portion under the seat, operator B needs to bend his / her waist every time the replacement work is performed, and the working posture of operator B deteriorates (see FIG. 5). Thereby, the burden on the waist of operator B increases. In FIG. 5, the white arrow indicates the height dimension difference between the portable battery 26 and the secondary power source P.

[0034] In the present embodiment, an entrance portion of the gap portion 48 of the vehicle 10 is provided with a partition member 56 that partitions the portable battery 26 and the passenger compartment space of the vehicle 10 (see FIG. 3).

[0035] According to the present embodiment, by providing the partition member 56 that partitions the portable battery 26 and the passenger compartment space of the vehicle 10, noise such as noise generated by the portable battery 26 can be shielded, and it is possible to prevent the noise such as noise from being input into the passenger compartment.

[0036] In the present embodiment, the partition member 56 has a substantially trapezoidal shape when viewed from the side of the vehicle, and is disposed on the inner side in the vehicle width direction rather than the vehicle width direction end portion 58 of the seating member 30. It is disposed on the inner side in the vehicle width direction by the dimension of the arrow shown in FIG. 3.

[0037] According to the present embodiment, by disposing the partition member 56 inside the vehicle width direction from the vehicle width direction end portion 58 of the seating member 30, when a side impact load is input to the vehicle 10, the vehicle width direction end portion 58 of the seating member 30 functions as an interfering member and can preferably protect the partition member 56. In other words, in the present embodiment, it is possible to suppress the partition member 56 from being damaged when a side impact load is input.

[0038] In the present embodiment, the space portion 48 of the vehicle 10 is provided with a charging device 60 (for example, a charging port from a household outlet) for the portable battery 26 (see FIG. 3).

[0039] According to the present embodiment, by providing the charging device 60 (for example, a charging port from a household outlet) for the portable battery 26 in the space portion 48, the portable battery 26 can be charged without being removed from the vehicle, and the convenience can be improved.

[0040] In the present embodiment, in a side view of the vehicle, the front backrest portion 44 is inclined forward of the vehicle from above the vehicle to below the vehicle, and the rear backrest portion 46 is inclined rearward of the vehicle from above the vehicle to below the vehicle. A space portion 48 that is recessed along the vehicle width direction is provided between the front backrest portion 44 and the rear backrest portion 46 of the seat back 38. This space portion 48 is configured in a substantially trapezoidal shape in a side view of the vehicle (see FIG. 2).

[0041] According to the present embodiment, by inclining the front backrest portion 44 and the rear backrest portion 46 of the seating member 30, respectively, the holding properties of the front occupant 12 and the rear occupant 32 are improved, and by configuring the space portion 48 in a substantially trapezoidal shape, the space in the vehicle front-rear direction can be increased as it goes from above the vehicle to below the vehicle, and the space efficiency in the vehicle interior can be improved.

[0042] Next, FIG. 6 shows a vehicle to which the seating member structure according to the third embodiment of the present invention is applied. Note that the same components as those in the second embodiment are denoted by the same reference numerals and the detailed description thereof is omitted.

[0043] In this embodiment, the vehicle 10b has a fixing portion 74 that fixes the seating member 70 to the floor portion 72 of the vehicle 10b, and a console (interior member) 76 that is disposed in front of the seating member 70 in the vehicle and extends along the vehicle width direction. An operation portion 78 for operating the movement of the vehicle in the vehicle longitudinal direction and / or the vehicle width direction is provided on one side of the console 76 along the vehicle width direction. The operation portion 78 is attached to the console 76 and supported by the console 76.

[0044] Examples of the operation portion 78 include a conventional steering mechanism such as a steering wheel, or a vehicle operation mechanism that also serves as an accelerator / brake operation by a pushing / pulling operation. The console 76 and the operation portion 78 are provided so as to be movable along the vehicle longitudinal direction (see the white arrow in FIG. 6).

[0045] According to this embodiment, even when the seating member 70 is fixed to the floor portion 72 of the vehicle 10 via the fixing portion 74 so as not to be slidable, the console (interior member) 76 and the operation portion 78 move in the vehicle longitudinal direction, respectively, so that it is not necessary to adjust the position of the seating member 70 in the vehicle longitudinal direction according to the physique (height and arm length) of the occupants (front occupant 12, rear occupant 32), and the gap portion 48 can be provided without moving from the area where the vehicle is to be arranged.

[0046] As described above, the present invention is not limited to the embodiments described above. For example, a plurality of portable batteries 26 may be arranged in the gap portions 28 and 48. In addition, further convenience can be improved by adopting a structure in which the seating member structure according to this embodiment is arranged symmetrically on both sides of the vehicle.
