The patent application (Publication Number: US20240009045A1) describes a powered midwheel drive (MWD) wheelchair with innovative features aimed at enhancing maneuverability and stability. The wheelchair includes a chassis, a seating system that can transition between seated and standing positions, a pair of drive wheels, front swing arms with front support wheels, and rear swing arms for force transfer. The front swing arms pivot in response to the seating system transitioning to the standing position, causing the chassis to tilt forward. This design ensures that the common center of gravity of the wheelchair and occupant is optimally positioned for stability.

Furthermore, the wheelchair incorporates resilient members, suspension arms, and linkage members to enhance the overall performance and comfort. The patent also details the positioning of the seat support at specific angles in the standing position, as well as the integration of a battery within the chassis. The front swing arms are designed to pivot passively to achieve forward tilting of the chassis, providing a lock-free front swing arm mechanism. Overall, the patented MWD wheelchair offers a unique combination of features to improve maneuverability, stability, and user experience for individuals with mobility challenges.
