Patent number: 10076976Abstract: A seat pedestal includes an open base upon which a plate assembly is mounted for translational movement upon the base. The plate assembly includes a bottom plate, a seat mount for supporting a seat, and a bearing means between the bottom plate and the seat mount to permit the seat mount to rotate. One lock releasably secures the plate assembly in the driving position and another, which is self-actuating, releases the seat mount so that it can rotate freely when it is in the resting position. A stop carried by the seat mount defines a range in which the seat may be rotated. At least one pair of interlocking members couples the seat mount with the bottom plate to transfer lateral loads born by the seat to the base. The bottom plate, the bearing means, and the seat mount have concentric openings through which wires may pass for accessories such as power/heated seats, headrests, and computer screens and related accoutrements.Type: GrantFiled: April 17, 2017Date of Patent: September 18, 2018Assignee: LIPPERT COMPONENTS MANUFACTURING, INC.Inventors: Timothy Roeglin, Hari Sunkara, Allan McGuire

Patent number: 10072945Abstract: A jack leveling apparatus utilizes a Hall effect sensor to determine a rate of movement of the jack leveling apparatus. The rate of movement is correlated to loading or unloading of the jack level device. When a load is applied to the jack level, the rate of movement will slow while alternatively, if a load is removed, the rate of movement will increase. Utilizing these values, the controller may also determine the position of the leg of the jack level device.Type: GrantFiled: June 29, 2016Date of Patent: September 11, 2018Assignee: LIPPERT COMPONENTS MANUFACTURING, INC.Inventor: Larry Allan McGuire
