Wheeled walker with a movable seat

A collapsible wheeled walker apparatus for facilitating a partially-supported walking gait on a walking surface for a user having one or two forearms and hands, the apparatus having a frame including a first side frame and a second side frame defining a polygonal footprint on the walking surface, the apparatus having a plurality of wheel assemblies coupled to the frame for supporting the frame above the walking surface and disposed at the vertices of the polygonal footprint, the apparatus comprising:

• a first upper body support and a second upper body support, each coupled to and disposed at an adjustable height above the respective side frame, wherein the adjustable height of each upper body support is adjusted by a respective height adjusting mechanism, and wherein each upper body support is coupled to a respective handle for gripping by a respective user hand;
• a seat apparatus including a seat member having a flexible material, a first side edge and a second side edge disposed at an approximately horizontal position, each side edge connected to a respective side slider, wherein each side slider is slidably coupled to a respective one of a first seat rail coupled to the first frame and a second seat rail coupled to the second side frame, such that the seat apparatus may be moved between an anterior walking position to provide an ample walking space inside the wheeled walker for the use and a posterior sitting position, the first seat rail and the second seat rail being substantially parallel to each other, each seat rail being tightly coupled to the respective side frame when the wheeled walker is at the open state and the seat apparatus is at the open seat state, and each seat rail being detached from the respective side frame when the wheeled walker is at the collapsed state and the seat apparatus is at the folded state;
• and
• an X-folder apparatus including an anterior element having two ends and a posterior element having two ends, the anterior element rotatably coupled to the posterior element, a second end of the anterior element of the X-folder being coupled to the seat rail coupled to the second side frame, and a second end of the posterior element of the X-folder being coupled to the seat rail coupled to the first side frame, such that rotation of the anterior element and the posterior element is adapted to move the X-folder between an open X-folder state and a closed X-folder state;
• wherein the seat apparatus is adapted to move between an open seat state and a folded seat state such that moving the X-folder apparatus into the open X-folder state urges the wheeled walker apparatus to an open state and urges the seat apparatus into the open seat state, and moving the X-folder apparatus into the closed X-folder state urges the wheeled walker apparatus into a collapsed state and urges the seat apparatus into the folded seat state.

• a seat apparatus including a seat member having two rigid side panels connected side-by-side by a hinge at the centerline of the seat member, a first side edge and a second side edge disposed at an approximately horizontal position, each side edge pivotally coupled to a respective side slider, wherein each side slider is slidably coupled to a respective seat rail that is affixed to the respective side frame, such that the seat apparatus may be moved between an anterior walking position to provide an ample walking space inside the wheeled walker for the user and a posterior sitting position;
• and
• an X-folder apparatus including an anterior element having two ends and a posterior element having two ends, the anterior element rotatably coupled to the posterior element, a first end of the anterior element rotatably coupled to the first side frame, a first end of the posterior element rotatably coupled to the second side frame, such that rotation of the anterior element and the posterior element is adapted to move the X-folder between an open X-folder state and a closed X-folder state, a second end of the anterior element of the X-folder being pivotally coupled to the seat rail affixed to the second side frame, and a second end of the posterior element of the X-folder pivotally coupled to the seat rail affixed to the first side frame;
• wherein the seat apparatus is adapted to move between an open seat state and a folded seat state such that moving the X-folder apparatus into the open X-folder state urges the wheeled walker apparatus to an open state and urges the seat apparatus into the open seat state, and moving the X-folder apparatus into the closed X-folder state urges the wheeled walker apparatus into a collapsed state and urges the seat apparatus into the folded seat state.
