Abstract
An electrically powered wheelchair has a main frame, a seat frame, a seat back frame, a footrest frame, a wheel section, and an obstacle detection sensor. The seat frame is disposed above the main frame, and supports a sitting seat which supports buttocks and thighs of a user. The seat back frame is disposed behind the main frame, and supports a backrest which supports a back of the user. The footrest frame is disposed in front of the main frame, and supports a footrest which supports feet of the user. The wheel section movably supports the main frame. The obstacle detection sensor is installed in front of the seat frame, and detects an obstacle.
Claims12
An electrically powered wheelchair comprising:
- a main frame;
- a seat frame that is disposed above the main frame, and supports a sitting seat which supports buttocks and thighs of a user;
- a seat back frame that is disposed behind the main frame, and supports a backrest which supports a back of the user;
- a footrest frame that is disposed in front of the main frame, and supports a footrest which supports feet of the user;
- a wheel section that movably supports the main frame;
- an obstacle detection sensor that is installed in front of the seat frame, and detects an obstacle within a sensing range on a front side of the electrically powered wheelchair;
- a foot cover that is attached to the main frame and regulates at least one of the feet of the user not to fall within a detection range of the obstacle detection sensor when the obstacle detection sensor performs detection by restricting a disposal range of the at least one of the feet of the user;
- and
- a sensor base that projects forward from the main frame, wherein:
- the obstacle detection sensor is installed on the sensor base, and
- the foot cover is installed on the sensor base.
An electrically powered wheelchair comprising:
- a main frame;
- a seat frame that is disposed above the main frame, and supports a sitting seat which supports buttocks and thighs of a user;
- a seat back frame that is disposed behind the main frame, and supports a backrest which supports a back of the user;
- a footrest frame that is disposed in front of the main frame, and supports a footrest which supports feet of the user;
- a wheel section that movably supports the main frame;
- an obstacle detection sensor that is installed in front of the seat frame, and detects an obstacle;
- a foot cover that regulates at least one of the feet of the user not to fall within a detection range of the obstacle detection sensor when the obstacle detection sensor performs detection;
- and
- a sensor base that projects forward from the main frame, wherein:
- the obstacle detection sensor is installed on the sensor base, and
- the foot cover is installed on the sensor base.

- an obstacle detection sensor that is installed in front of the seat frame, and detects an obstacle;
- a foot cover that regulates at least one of the feet of the user not to fall within a detection range of the obstacle detection sensor when the obstacle detection sensor performs detection;
- an operation lever that is movable in back and forth and right and left so that the user can drive the electrically powered wheelchair in a traveling direction;
- a sensor base that projects forward from the main frame;
- a controller that detects a swinging direction in back and forth and right and left applied to the operation lever, and controls the operation of the wheel section;
- and
- a rotation drive device that moves the sensor base on the same side as a direction of a movement component to an outside of the electrically powered wheelchair in a case where the movement component to right or left is detected as a direction applied to the operation lever;
- wherein the obstacle detection sensor is installed on the sensor base;
- component to right or left is detected as a direction applied to the operation lever.
