Description

Welfare vehicles

The present invention relates to a welfare vehicle including a lift device that moves a wheelchair from the inside of the vehicle to the inside of the vehicle or from the inside of the vehicle to the outside of the vehicle, and a wheelchair fixing device that fixes the wheelchair accommodated in the vehicle to a predetermined position in the vehicle.

In recent years, welfare vehicles enable a cared person in a wheelchair to drive a driver's seat together with a wheelchair, or to allow a cared person in a wheelchair to get in with the wheelchair to prevent various misoperations. Various safety devices are provided. However, the safety device sometimes makes the welfare vehicle unusable.
For example, in the conventional technology described in Patent Document 1, in a welfare vehicle in which a cared person riding in a wheelchair can drive the driver's seat together with the wheelchair, the engine can be started when the wheelchair is fixed to the driver's seat. With respect to the safety device that has been provided, a safety device is disclosed in which the engine can be safely started with a remote controller even before the wheelchair is fixed to the driver's seat (before boarding the vehicle).
