US Patent 11712382 Wheelchair with dynamic occupant-tilt feature

A wheelchair having a tiltable occupant-support assembly, a powered drive system for adjusting the degree of tilt, and a control system for varying the degree of tilt in a programmatic automated fashion. The wheelchair is programmed or programmable to vary the degree of tilt, and therefore the wheelchair's occupant, automatedly. The wheelchair may provide pre-set ranges of seating angles and durations of time at each angle of tilt. The wheelchair thereby allows for reliable off-loading of the occupant's weight from pressure points, to avoid pressure ulcers, and does so programmatically so as to reduce the burden on healthcare staff and professionals while also ensuring adherence with prescribed tilting schedules.
