DETAILED DESCRIPTION

The systems and methods described herein generally relate to powered wheelchair apparatuses that include various usage features that assist users in daily activities and pursuit of individual interests in addition to providing a mode of transportation. The usage features may include, for example, addition of storage locations, lighting features, device charging locations, etc. The various usage features can be integrated into the powered wheelchair apparatuses so as to not interfere with ordinary usage of the powered wheelchair apparatuses, while being integrated into a body structure of the powered wheelchair apparatuses, such as into a seat, armrests, and the like.

As used herein, the term “longitudinal direction” refers to the forward-rearward direction of the wheelchair apparatus (i.e., in a +/−X direction of the coordinate axes depicted in FIG. 1). The term “lateral direction” refers to the cross-direction (i.e., along the y axis of the coordinate axes depicted in FIG. 1), and is transverse to the longitudinal direction. The term “vertical direction” refers to the upward-downward direction of the system (i.e., in the +/−Z-direction of the coordinate axes depicted in FIG. 1). As used herein, “upper” or “top” is defined as generally being towards the positive Z direction of the coordinate axes shown in the drawings. “Lower” or “bottom” is defined as generally being towards the negative Z direction of the coordinate axes shown in the drawings.

Referring to FIGS. 1 and 2, a wheelchair apparatus 10 generally includes a power base component 12 and a chair component 14.
