Publication number: 20220071821Abstract: A wheelchair comprises a base assembly and a tilt assembly detachably supported on the base assembly. The base assembly has a mounting point that receives the tilt assembly and a latch receiver that engages a latch assembly of the tilt assembly. The wheelchair further provides a fore and aft adjustment of a seat mounted to the tilt assembly and an angular adjustment of the seat relative to a rocker of the tilt. Each of the fore/aft seat adjustment and the seat angle adjustment relative to the rocker is independently adjustable. The rocker position of the tilt assembly relative to the base is unchanged when either the seat longitudinal position or angular position is adjusted.Type: ApplicationFiled: November 15, 2021Publication date: March 10, 2022Applicant: Sunrise Medical (US) LLCInventor: Samuel D.

Publication number: 20220062076Abstract: A propulsion system for a manual wheelchair includes a mounting clamp and a propulsion drive unit having a drive wheel assembly and a support suspension. The support suspension is configured to provide linear movement of the drive wheel and drive hub assembly relative to the manual wheelchair. The support suspension includes a linear bearing and slide member assembly having at least one linear bearing and a slide member for accommodating the linear movement of the drive wheel assembly and further includes a resilient suspension member that provides a tractive effort force to the drive wheel. The drive wheel assembly is supported on a carriage that is attached to one of the at least one linear bearing or the slide member and a mounting block is attached to the other. The mounting block has a clamp interface with a locating tab that engages a corresponding mounting slot in the mounting clamp.Type: ApplicationFiled: December 23, 2019Publication date: March 3, 2022Applicant: Sunrise Medical (US) LLCInventors: Samuel Traxinger, Mark Greig, Jefferey Bashian, Daniel Zhou

Patent number: 11248153Abstract: A seating system, particularly suited for personal mobility vehicles, such as wheelchairs, that includes a seat cushion having pressure relieving properties and enhanced thermal absorption properties. The seat cushion includes a thixotropic fluid contained within a flexible envelope. The thixotropic fluid includes a phase change material that enhances the thermal absorption properties of the seat cushion to increase thermal absorption from a seated user to provide a reduced temperature sensory effect. The thixotropic fluid further includes a thermal conduction medium that facilitates heat distribution to the phase change material.Type: GrantFiled: May 25, 2018Date of Patent: February 15, 2022Assignee: Sunrise Medical (US) LLCInventor: Marc Lalouette

Patent number: 10869794Abstract: A reversible seating mechanism includes a frame and a cross member pivotally supported on the frame for rotational movement in a plane generally parallel to the frame to define a tilt angle. A mounting plate is pivotally supported on the cross member for rotational movement in a plane generally parallel to the cross member to define one of a forward and rearward facing orientation. The mounting plate is moveable on the cross member to be oriented to the tilt angle. A tilt limiter restricts movement of the mounting plate between the forward and rearward facing orientations until the tilt angle is adjusted to a preset angle. The tilt limiter limits a forward facing tilt angle to an angle less than a rearward tilt angle.Type: GrantFiled: June 19, 2017Date of Patent: December 22, 2020Assignee: Sunrise Medical (US) LLCInventors: Steven L.
