Patent number: 11701277Abstract: Systems, methods, and devices for seat elevation includes a base and a horizontal seat portion. Vertical supports attached to the seat portion include multiple lift angle holes that allow the seat to be elevated to different lifted angles. Elongate members pivotally connect to vertical supports. The elongate members attach via one of the multiple lift angle holes. The elongate members are able to attach to different lift angle holes. The lifted angle is determined by the first one of the at least two seat position holes. A lift generator is attached to the base and extends to lift the horizontal seat portion into the lifted position. The lift generator contracts to return the horizontal seat portion to the seated position.Type: GrantFiled: August 2, 2022Date of Patent: July 18, 2023Assignee: Liftseat CorporationInventor: Jeffrey Cogan Nelson

Publication number: 20140338119Abstract: Devices and methods are presented for elevating seat devices. The device allows a vertical and forward motion of a seat from a first position to a second position. Such motion more resembles a natural body motion during the standing motion. A similar but converse motion is also possible with movement from a standing position to a sitting position.Type: ApplicationFiled: May 14, 2013Publication date: November 20, 2014Applicant: LIFTSEAT CORPORATIONInventors: Graham Robert Byrne Henshaw, Daniel A.

Publication number: 20100219668Abstract: Devices and methods are disclosed which relate to lifting a user from a seated position to a raised position. This is performed by incorporating a lifting mechanism into a seat coupled to a movable base portion. Actuators coupled to drive shafts enable a plurality of linkages to be raised and tilted, enabling the seat to rise at the push of a button or other triggering mechanism. A plurality of compressible springs enables an even balance between the weight of the human and the pressure of the lifting mechanism underneath the seat. As the lifting portion lifts the seat, an angle of the seat changes from a substantially horizontal position to a relatively angled position, mimicking the natural motion of the hips and thighs for humans needing assistance. Embodiments disclosed include using the device as a bedside toilet, having a removable bowl attached to the seat, or using the device placed over a toilet.Type: ApplicationFiled: May 20, 2010Publication date: September 2, 2010Applicant: LIFTSEAT CORPORATIONInventors: Jeffrey C.
