  • Seat Lift With Non-Linear Spring Assist
    Publication number: 20230058230
    Abstract: The present invention provides an assembly having a wheelchair and a lift assembly to urge the seat surface upward with respect to the frame from a lowered position when supporting a seated individual during use to an elevated position with respect to the frame as to assist the individual during ingress or egress to or from the wheelchair. The lift assembly may include a mechanical linkage and an actuator assembly. The actuator assembly produced a nonlinear lift force having a first period exhibiting a first rate of amplitude increase when the seating surface is nearer the lowered position and a second period exhibiting a second rate of amplitude change that is less than the first rate of amplitude increase when the seating surface is nearer the elevated position.
