  As shown in FIG. 11, the door lining 13 a ′ of the door 13 of the vehicle 11 that does not include the occupant transfer device 14 has protrusions such as the cup holder 13 b ′ protruding into the vehicle interior, but includes the occupant transfer device 14. The door lining 13a of the door 13 of the vehicle 11 is replaced with one in which the protrusions such as the cup holder 13b 'do not protrude into the vehicle interior.

  Next, the operation of the embodiment of the present invention having the above configuration will be described.

  In order to transfer the person on the wheelchair to the seat 12 of the vehicle 11, from the state of FIG. 10A, the assistant first opens the door 13, and the transfer board 25 of the slide unit 24 locked in the lowered position. Is moved from the stowed position to the overhanging position that extends horizontally outward in the vehicle width direction, and then the person being assisted in the wheelchair is moved to the transfer board 25.

  Subsequently, as shown in FIG. 8B, when the first swing plate 46 is swung counterclockwise by pulling the operation lever 48 upward against the elastic force of the torsion spring 53. The second swing plate 50 swings counterclockwise via the link 52, the hook 54 integral with the second swing plate 50 rotates counterclockwise, and the first engaging portion 54a becomes the lower striker 55. The transfer board 25 can be lifted together with the slide unit 24.

  At this time, the elastic force of the gas damper 26 and the coil spring 44 is set to be slightly smaller than the weight of the person being assisted, so the assistant lifts the transfer board 25 upward, or the person being assisted kicks the ground. 10B, the transfer board 25 rises along the guide rails 23 and 23 together with the slide unit 24, as shown in FIG. When the slide unit 24 moves up, the second cam surface 54d of the second engaging portion 54b of the hook 54 comes into contact with the upper striker 56, so that the hook 54 resists the elastic force of the torsion spring 53 and counterclockwise. 7b, after the second engaging portion 54b gets over the upper striker 56, it is automatically engaged with the upper striker 56 by the elastic force of the torsion spring 53, as shown in FIG. The slide unit 24 is locked in the raised position. When the slide unit 24 reaches the raised position, the transfer board 25 becomes substantially the same height as the seating surface of the seat 12, so that the person being assisted moves from the transfer board 25 into the passenger compartment as shown in FIG. Thus, the seat 12 can be transferred.

  When the person being assisted is transferred to the seat 12 in this manner, the assistant raises the operation lever 48 to disengage the second engaging portion 54b of the hook 54 from the upper stoichia 56 as shown in FIG. 7B. Thereafter, when the transfer board 25 is pushed down against the resilience of the gas damper 26 and the coil spring 44, the first engagement portion 54a of the hook 54 is connected to the first cam surface 54c as shown in FIG. The lower striker 55 is automatically engaged by the action, and the slide unit 24 is locked at the lowered position. Therefore, as shown in FIG. 10A, the door 13 can be closed without interfering with the transfer board 25 by folding the transfer board 25 upward from the extended position to the storage position.

  In order to transfer the person being assisted from the seat 12 to the wheelchair, the door 13 is opened and the transfer board 25 is brought down to the extended position, and then the slide unit 24 is moved from the lowered position to the raised position. After being raised and locked, the person being assisted is moved from the seat 12 to the transfer board 25. Subsequently, when the operation lever 48 is operated to disengage the second engaging portion 54b of the hook 54 from the upper striker 56, the weight of the person being assisted is larger than the elastic force of the gas damper 26. The gas damper 26 is lowered while being compressed, and further reaches the lowered position while the coil spring 44 is being compressed while the gas damper 26 is being lowered, and the first engagement portion 54a of the hook 54 is automatically engaged with the lower striker 55, and the transfer board. 25 is locked. Subsequently, it is possible to close the door 13 without interfering with the transfer board 25 by moving the person being assisted from the transfer board 25 to the wheelchair and folding the transfer board 25 upward from the extended position to the retracted position. Become.

  As described above, the floor panel 21 and the slide unit 24 are connected by the gas damper 26, and the slide unit 24 is urged upward by the elastic force of the gas damper 26. Therefore, the weight of the person being assisted and the gas damper 26 By balancing the elastic force, the person being assisted can be lifted and lowered with very little force. In addition, it does not require a special drive source such as a motor, so that it can be realized at low cost, and it has a compact structure that compresses the cabin space and interferes with getting on and off of a healthy person. There is nothing.

  In addition, it is possible to deal with a person who has a different weight by changing the position of the upper joint 42 of the gas damper 26 relative to the slide unit 24 back and forth (see FIG. 2) without replacing the gas damper 26 itself. Can do. That is, if the position of the upper joint 42 is moved forward, the inclination angle of the gas damper 26 with respect to the vertical direction increases, so that the vertical component of the elastic force of the gas damper 26 is reduced, so A suitable elastic force can be obtained, and conversely, if the position of the upper joint 42 is moved backward, the inclination angle of the gas damper 26 with respect to the vertical direction becomes smaller, so the vertical component of the elastic force of the gas damper 26 is reduced. The elasticity can be increased and the elasticity suitable for a person who is heavy can be obtained.

  When the slide unit 24 is in the lowered position, the gas damper 26 is in the most lying position, so that the vertical component of the elastic force becomes small, and the transfer board 25 carrying the person being assisted starts to rise. It tends to run out of elasticity. However, when the transfer board 25 starts to rise, the elastic force of the gas damper 26 is assisted by the elastic force of the coil spring 44, so that the transfer board 25 starts to rise smoothly by applying a slight force. be able to.

  Further, since the upper end portion of the gas damper 26 is offset outward in the vehicle width direction with respect to the lower end portion (see FIG. 3), the slide unit 24 to which the weight of the person sitting on the transfer board 25 is added is more efficient by the gas damper 26. Thus, it is possible to prevent the outer end of the transfer board 25 in the vehicle width direction from being hung downward and preventing smooth elevation.

  As shown in FIGS. 2 and 6, when the frame 22 of the occupant transfer device 14 is assembled to the vehicle body, the front frame 28 is attached to the front mounting holes 21a of the floor panel 21 for fixing the seat front legs 12a, 12a. The rear frame 29 is fixed to the rear mounting holes 21b and 21b of the floor panel 21 for fixing the seat rear legs 12b and 12b via the rear bracket 33, and is fixed to the base frame. 27 is fixed to the component mounting holes 21c... Of the floor panel 21 for fixing the vehicle-mounted components via the first to third center brackets 34, 35, 36. The front mounting holes 21a and 21a, the rear mounting holes 21b and 21b, and the component mounting holes 21c. That. Thereby, the vehicle 11 provided with the occupant transfer device 14 can be shared with the vehicle 11 not provided, and the cost for installing the occupant transfer device 14 can be reduced. Further, if the occupant transfer device 14 is fixed to the inner wall surface of the passenger compartment or the seat 12 itself, there is a possibility that the occupant gets in and out of the vehicle or the function of the seat 12 may be impaired, but by fixing it to the floor panel 21 The above problem can be solved.

  Further, since the front frame 28 is fixed in the vicinity of the front mounting hole 21a located on the outer side in the vehicle width direction via the front bracket 32, the length of the front frame 28 located on the front side of the seat 12 is shortened. Can be prevented.

  Further, since the rear frame 29 is fixed in the vicinity of the rear mounting hole 21b located on the inner side in the vehicle width direction via the rear bracket 33, the frame 22 is placed on the outer side in the vehicle width direction due to the weight of the person sitting on the transfer board 25. Even if a moment to tilt is applied, the tilt of the frame 22 can be prevented by effectively supporting the moment with the long moment arm of the rear frame 29. Even if the rear frame 29 extends inward in the vehicle width direction, the rear frame 29 is positioned on the rear side of the seat 12 and therefore does not interfere with the passenger.

  Further, since the door 13 facing the occupant transfer device 14 is a slide door, the thickness can be made smaller than that of a normal door pivotally supported by a hinge, and a space for disposing the occupant transfer device 14 between the seat 12 and the seat 12. It is possible not only to easily secure the door, but also to widen the door opening and make it easier to get on and off the person being assisted. Further, since the passenger compartment side surface of the door lining 13a is substantially flat (see FIG. 11B), the door lining 13a does not interfere with the occupant transfer device 14 when the door 13 is opened and closed.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, the elastic member of the present invention is not limited to the gas damper 26 according to the embodiment, and may be a spring damper in which a coil spring is accommodated in a cylinder.

  In the embodiment, the position of the upper joint 42 of the gas damper 26 is movable, but the position of the lower joint 43 may be movable.

  In the embodiment, the occupant transfer device 14 is provided on the seat 12 on the right side of the vehicle body, but it may be provided on the seat on the left side of the vehicle body.
