Abstract

An electric passenger transport vehicle according an embodiment may include: a vehicle body including a floor, a first seat base, a second seat base provided on a rear side of the first seat base; a first seat including a first seat bottom attached to an upper surface of the first seat base; and a second seat including a second seat bottom attached to an upper surface of the second seat base. The second seat bottom is supported by the vehicle body such that the second seat bottom is movable between a first position in which a bottom surface of the second seat bottom is positioned above an upper surface of the second seat base and faces downward and a second position in which the bottom surface of the second seat bottom is positioned in front or back of the upper surface of the second seat base and faces upward.

Claims (49)

1 . A passenger transport vehicle comprising:

a vehicle body including a floor, a first seat base, a second seat base provided on a rear side of the first seat base;

a first seat including a first seat bottom attached to an upper surface of the first seat base; and

a second seat including a second seat bottom attached to an upper surface of the second seat base, wherein

the second seat bottom is supported by the vehicle body such that the second seat bottom is movable between a first position in which a bottom surface of the second seat bottom is provided above the upper surface of the second seat base and faces downward and a second position in which the bottom surface of the second seat bottom is provided in front of or in back of the upper surface of the second seat base and faces upward,

a pair of armrests are fixed to left and right end portions of the second seat bottom and are configured to move together with the second seat bottom, and

each armrest of the pair of armrests includes a contact portion configured, when the second seat bottom is moved to the second position, to come in contact with the floor such that the second seat bottom is supported by the floor via the pair of armrests at the second position of the second seat bottom.

2 . The passenger transport vehicle according to claim 1 , wherein

the bottom surface of the second seat bottom is provided, at part of a peripheral edge thereof, with a flange projecting in a direction crossing the bottom surface of the second seat bottom.

3 . The passenger transport vehicle according to claim 1 , wherein

at least one of the contact portion and a portion of the floor that comes in contact with the contact portion is provided with a damper.

4 . The passenger transport vehicle according to claim 1 , wherein

the contact portion is provided at a rear end portion of each armrest of the pair of armrests.

5 . The passenger transport vehicle according to claim 1 , wherein

each armrest of the pair of armrests includes a flange portion projecting downward from a position corresponding a peripheral edge portion of the bottom surface of the second seat bottom.

6 . The passenger transport vehicle according to claim 5 , wherein

the flange portion of each armrest of the pair of armrests includes a hook portion or a hole.

7 . The passenger transport vehicle according to claim 1 , wherein

the bottom surface of the second seat bottom is provided with a plurality of attachment holes for attaching an accessory to the bottom surface of the second seat bottom.

8 . The passenger transport vehicle according to claim 1 , wherein

the second seat bottom is overlapped with a rear axle of the vehicle in a vertical direction.

9 . The passenger transport vehicle according to claim 1 , further comprising

an electric motor configured to drive a front wheel or a rear wheel of the vehicle, wherein

the second seat bottom is overlapped with the electric motor of the vehicle in a vertical direction.

10 . The passenger transport vehicle according to claim 1 , wherein

in a cross sectional view of the vehicle taken along a line extending in a vehicle width direction through the first seat, an outer end of the floor is located on the outermost side of the vehicle body.

11 . The passenger transport vehicle according to claim 1 , wherein

a rear end of the second seat bottom is located on a rear side of a front end of a rear wheel of the vehicle.

12 . The passenger transport vehicle according to claim 1 , wherein

a seating surface of the second seat bottom is located at a position higher than a seating surface of the first seat bottom.

13 . The passenger transport vehicle according to claim 1 , wherein

a gap is formed between a lower end of a second seat back and the upper surface of the second seat base in a vertical direction.

14 . A passenger transport vehicle comprising:

a vehicle body including a floor, and plural seat bases spaced apart from each other in a longitudinal direction of the vehicle body and projecting upward from the floor; and

a seat including a seat bottom attached to an upper surface of one of the plural seat bases and a seat back, wherein

the seat bottom is supported by the vehicle body to be movable between: a first position in which a bottom surface of the seat bottom faces downward toward the upper surface of the one seat base; and a second position in which the bottom surface of the seat bottom is located in front of the upper surface of the one seat base and faces upward, thereby forming a loading surface by the upper surface of the one seat base and the bottom surface of the seat bottom in the second position,

the seat back is rotatably supported by the vehicle body such that the seat back is developable from a normal position in which the seat back is located above a rear end portion of the seat bottom and functions as a backrest for a passenger seated on the seat bottom to a retracted position different from the normal position,

the seat back includes a front surface for supporting a back of the passenger seated on the seat bottom,

in the normal position, the seat back is positioned such that the front surface of the seat back faces toward a front of the vehicle,

in the retracted position, the seat back is positioned: (i) above the normal position such that the front surface of the seat back faces upward; or (ii) below the normal position such that the front surface of the seat back faces a rear of the vehicle, and

the seat back in the retracted position is located on a rear side or an upper side of the loading surface, which is formed by the upper surface of the one seat base and the bottom surface of the seat bottom in the second position.

15 . The passenger transport vehicle according to claim 14 , wherein

in the normal position of the seat back, a gap is formed between a lower end portion of the seat back and the rear end portion of the seat bottom,

the seat back is developable from the normal position of the seat back to the retracted position (ii) below the normal position, and

at the retracted position of the seat back (ii) below the normal position, the seat back is positioned to cover the gap.

16 . The passenger transport vehicle according to claim 14 , wherein

the seat back is rotatably supported about a rotational axis such that the seat back is developable from the normal position to the retracted position.

17 . The passenger transport vehicle according to claim 14 , wherein

the vehicle body further comprises front pillars and rear pillars, wherein the seat back is rotatably supported by the rear pillars of the vehicle body.
