Description

  The present invention relates to an automobile seat, and more particularly to an automobile seat that assists in getting on and off an automobile.

  In recent years, with the enhancement of nursing care facilities, there have been increased opportunities for transporting care recipients from home to nursing care facilities by passenger cars. Along with this, devices for assisting in getting on and off automobiles have been developed for physically challenged persons such as physically challenged persons and elderly persons. For example, a seat lifting / lowering device configured by a rotating device that rotates a seat arranged toward the front of the vehicle toward the opening on the side of the vehicle and a lifting device that moves the rotated seat down while moving it outside the passenger compartment. An apparatus is disclosed (for example, see Patent Document 1). FIG. 4 shows an example of a device that moves the seat laterally and then moves it out of the vehicle by the electric slide device.

Furthermore, a method of carrying a wheelchair into the vehicle and fixing it to the vehicle body floor, or a vehicle seat that is equipped with wheels on the seat and can be used as a wheelchair as it is moved out of the passenger compartment are disclosed (for example, see Patent Document 2). ).
These conventional boarding and alighting care devices use electric slides that utilize a driving force such as a motor, and the devices are complicated, heavy, and expensive. In addition, it is necessary to change the electrical system for installation, and it is not easy to remodel the vehicle in use and attach the boarding / exiting care device. There was no choice but to buy a vehicle equipped with a care device.

  Situations in which the physically handicapped or the elderly have to be cared for, and temporary disabilities such as lumbar hernia, occur in unexpected times. A device to assist is needed. However, it is difficult to purchase a car with a dedicated device. In addition, when the device for assisting getting on and off is not used, it becomes an obstacle and the period for which the device is required is unknown. For this reason, there has been a demand for an automobile seat with improved boarding / exiting capability that can assist a person with a physical disability or an elderly person to get on and off a vehicle by improving the vehicle in use by a simple method.
