[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a seat (seat) for a two-seater bus seat installed in a sightseeing bus.

[0002]

2. Description of the Related Art A conventional seat of this type is provided with a reclining device so that a seat back can be adjusted to a desired inclination angle of a seated person. This pivots the entire seat back in the front-rear direction. When the seat back is tilted backward, the seat back of the fallen front seat protrudes toward the rear occupant seated behind. For this reason, the space on the rear seat side is restricted, and there is a problem that it is difficult for the occupant in the rear seat to take off or take a seat. In addition, when a seated person on one seat falls down, the other seatback is independent, so that a step is generated between the headrests of the left and right seats. Therefore, the left and right seats using both headrests are uncomfortable and the appearance of the seat from the back side is very bad. Therefore, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a seat having a good appearance and excellent usability in a passenger compartment of a bus.

[0003]

Means for Solving the Problems To achieve the above object, a seat for a bus passenger compartment according to the present invention is provided with a pair of left and right movably mounted on the left and right sides of a pedestal fixed to the vehicle floor via slide rails. A seat back and a backrest for supporting a headrest fixed to the rear end of the pedestal in an upright state. An upper end is pivotally connected to the headrest fixed to the backframe so as to be rotatable, and a lower part is the seat cushion. And a pair of left and right seat backs that are connected to the seat cushion so as to be tiltable with the forward movement of the vehicle.

[0004]

When the seat cushion is moved forward, the seat back pivots about the upper part, and the lower part moves forward, and the seat back tilts. However, since the headrests of the left and right seats and the upper portion of the seatback are integrally fixed to the back frame, they do not move due to the movement of the seat cushion in the front-rear direction.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. (1) in the figure is fixed to the car floor in the cabin of the sightseeing bus and a pair of left and right seat cushions (SC)
C ') is shown, and a back frame (2) made of a pipe is fixed to the rear of the pedestal (1) in an upright manner as shown in FIG. The above seat cushion (S
C) and (SC ′) can be moved independently in the front-rear direction, respectively, through the slide rails (3) and (3).
Mounted on Upper rail (31) for fixing the slide rail (3) to the seat cushion (SC) side
And a lower rail (32) in which the upper rail (31) is slidably fitted back and forth.
2) is fixed to the base (1). In the figure, (3 ') indicates an operation lever for unlocking the slide rail (3).

As shown in FIG. 3, movable rods (33) (33) bent in a substantially rectangular shape are integrally formed on the left and right ends of the cushion frame (44) of each of the above-mentioned seat cushions (SC). Rollers (34) and (34) are fixed to the upper ends of the movable rods (33) and (33) by bolts (35) and nuts (3).
8) is rotatably mounted on the shaft. In the figure (37)
Indicates a bush. The above rollers (34) and (34)
As shown in FIG. 4, it is movably mounted in U-shaped guide rods (36) (36) provided on the left and right ends of the lower end of the seat back (SB).

A headrest (HR) is fixed to the top of the back frame (2).
As shown in FIG. 2, R) is a left and right integrated headrest fixed above the left and right seat backs (SB) (SB ').

The upper end of the seat back (SB) (SB ') is hinged to the back frame (2).
That is, the link (4) whose lower end is fixed to the seat back frame (43) of the seat back (SB) (SB ').
2) and a link (41) whose upper end is fixed to the back frame (2) are rotatably connected by hinge pins. (6) in the figure indicates a shielding curtain.

Thus, when the lock release operation lever (3 ') is operated to move from the right seat cushion (SC') position shown in FIG. 2 to the seat cushion (SC) position shown on the left side in FIG. In conjunction therewith, the movable rods (33) (33) integral with the seat cushion (SC) move forward of the seat cushion (SC). Therefore, the lower part of the seat back (SB) is pivoted forward about the upper end, and the whole is tilted as shown in FIG. When the unlocking operation lever (3 ') is operated again to move the seat cushion (SC') backward, the seat cushion (SC ') on the right side shown in FIG. ) Changes from the inclined state to the upright state.

[0010]

According to the present invention, even when the seat back is tilted, the upper end of the seat back is attached to the back frame, so that the seat back does not project in the rear seat direction. Therefore, the space for the rear seat is always kept constant, so that the movement of the rear occupant for taking off and taking the seat is not hindered, and the appearance of the seat from the back side is improved. In addition, since the headrest is always fixed at a fixed position, even if one of the left and right occupants tilts the seat back, a step occurs between the occupant's headrest and the other occupant's headrest. Absent. Therefore, the left and right occupants using the headrest do not feel uncomfortable. Further, since the seat back tilts at the same time as the seat cushion moves forward, the reclining operation of the seat back becomes unnecessary.
