Description

  The present invention relates to an auxiliary chair of a vehicle for a disabled person, and more particularly, transfer from a wheelchair to a vehicle with a high chair position due to a problem with a waist or leg, and conversely, transfer from a vehicle with a high chair position to a wheelchair. The present invention relates to an auxiliary chair of a vehicle for a disabled person that enables a person who is difficult to transfer from a wheelchair to a vehicle with a high chair position and vice versa.

  There are people who have difficulty in transferring from a wheelchair to a vehicle with a high chair position due to a disability in the waist and legs, and vice versa. In particular, recently, the height of vehicles called one-box cars and UV cars is high, and the seats in the driver's seat, front passenger seat, and passenger seat are very high, and it is difficult or impossible for disabled people to transfer from wheelchairs. is there.

  Conventionally, a person who has difficulty in transferring from a wheelchair to a vehicle with a high chair position due to a problem with a lower back or a leg, and vice versa. In order to transfer to a vehicle with a high position and vice versa, a fixed-height fixed auxiliary chair is used to transfer from a vehicle with a high chair position to a wheelchair with a low seat. As shown in FIG. 5, the fixing auxiliary chair is fixed on the vehicle floor 100 by disposing a fixing leg 110 between the vehicle seat 102 and the door frame 104 or between the vehicle seat 102 and the vehicle floor 100. The legs 110 are fixed to the vehicle floor 100 with vehicle seat fixing bolts (not shown). The side board 120 for seating is fixed by inserting two fixing pipes 122 provided on the bottom surface thereof into a vertical hole 124 provided in the fixing leg 110. The sideboard 120 is pivotally supported with respect to the fixed pipe 122, and can be changed between a horizontal state indicated by a solid line in FIG. 5 and a vertical state indicated by an imaginary line in FIG.

  In addition, lift-type swivel chairs are manufactured in order to transfer from a wheelchair having a low seat to a vehicle having a high seat position, and conversely from a vehicle having a high chair position to a wheelchair having a low seat. As shown in FIG. 6, the vehicle seat 200 in the passenger seat is rotated outward from the front direction at a predetermined position when the vehicle is moving. Furthermore, the lift device lowers the vehicle seat 200 facing outward from the height when the vehicle travels to a height at which the disabled person can transfer to the wheelchair.

In the above-described fixing auxiliary chair, when the door is closed, the sideboard 120 is manually brought into a vertical state in order to avoid interference between the sideboard 120 and the inner surface of the door. The vehicle door has an armrest. The armrest protrudes to the inside of the vehicle at a position higher by about 10 to 15 cm than the height of the driver seat. Accordingly, the sideboard 120 is in a vertical state in order to avoid interference with the door, but there is a problem that the size of the sideboard 120 is limited in order to avoid interference with the armrest. In order to avoid interference with the armrest, it is possible to remove the side board 120 from the fixed leg 110 after the transfer, but the inconvenience actually prevents the use of the fixing auxiliary chair.
In addition, if the fixed auxiliary chair with a fixed height is set to be deployed and used at a low position in order to avoid interference with the armrest, the difference in height between the fixed auxiliary chair and the driver seat increases. There is a problem that it becomes difficult to transfer between the fixing auxiliary chair and the driver's seat.

  On the other hand, the above-described lift-type swivel chair is very expensive because it requires complicated and advanced technology, and its weight is large, which adversely affects the running performance and fuel consumption of the vehicle. Furthermore, the vehicle chair itself must be remodeled from a so-called standard product specification, which has become low-cost due to mass production, to a special specification, which also inevitably increases the price. On the other hand, since the lift-type swivel chair protrudes from the side of the vehicle when in use, it is highly likely that it will be very difficult or impossible to use in a garage or parking space of a limited area for ordinary vehicles. . Furthermore, the lift-type swivel chair has a great limitation that it cannot be mounted on the driver's seat because the handle interferes with the rotation.
