Wheelchair

A folding wheelchair on which a wheelchair user can be seated, the wheelchair comprising:

• a left side frame that axially supports a drive wheel on a left side of a body;
• a right side frame that axially supports a drive wheel on a right side of the body;
• a support arm that couples the left side frame and the right side frame and is folded in a central portion in a left-right direction;
• a footrest that couples a front end portion of the left side frame and a front end portion of the right side frame and is folded in a central portion in the left-right direction;
• and
• a rod that connects the central portion of the support arm in the left-right direction and the central portion of the footrest in the left-right direction;
• wherein
• the footrest has a left footrest component that constitutes a left portion of the footrest;
• a right footrest component that constitutes a right portion of the footrest;
• and a bracket that couples a right end portion of the left footrest component and a left end portion of the right footrest component in a manner to allow rotation thereof;
• the bracket is disposed in an opening that is formed between the right end portion of the left footrest component and the left end portion of the right footrest component, and is held between the left footrest component and the right footrest component from left and right sides when the footrest is unfolded;
• the support arm includes an upper support arm folded in an upward direction and a lower support arm folded in downward direction;
• the upper support arm has a first upper arm component that constitutes a left portion of the upper support arm, a second upper arm component that constitutes a right portion of the upper support arm, and an upper coupling member that couples a right end portion of the first upper arm component and a left end portion of the second upper arm component in a manner to allow rotation thereof;
• the lower support arm has a first lower arm component that constitutes a left portion of the lower support arm, a second lower arm component that constitutes a right portion of the lower support arm, and a lower coupling member that couples a right end portion of the first lower arm component and a left end portion of the second lower arm component in a manner to allow rotation thereof;
• an engagement section is fixed to a rear side of the upper coupling member, an engaged section is fixed to a front side of the lower coupling member, an upper end of the rod is fixed to a front side of the upper coupling member, and a lower end of the rod is jointed to the bracket;
• when transitioning from an unfolded state to a folded state, the upper coupling member is moved upwardly, pulling the rod and causing folding upwardly of the left footrest component and the right footrest component;
• and
• when transitioning from the folded state to the unfolded state, the first upper arm component and the second upper arm component expand in the left-right direction, the upper coupling member downwardly pushes the rod and expands the left footrest component and the right footrest component in the left-right direction until the engagement section and the engaged section are engaged.
