Abstract

A method of positioning a vehicle seat is provided in which the vehicle seat is configured to allow movement laterally (i.e., side-to-side), fore-aft (i.e., forwards-backwards), and rotationally. In addition to allowing a user to select a particular seat position, the method monitors an internal vehicle door handle and automatically moves the seat from its current position to a preset position whenever the door handle is activated (e.g., touched).

8. The method of claim 1, wherein said seat position selector is comprised of at least one multi-positional switch, wherein said step of detecting selection of said particular seat position further comprises determining a direction of movement of said at least one multi-positional switch, wherein said direction of movement is selected from a plurality of available switch movement directions, wherein each of said plurality of available switch movement directions corresponds to a preset direction of motion of said vehicle seat via said seat positioning system, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a first direction, wherein said first direction corresponds to movement of said vehicle seat in said forward direction, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a second direction, wherein said second direction corresponds to movement of said vehicle seat in said backwards direction, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a third direction, wherein said third direction corresponds to movement of said vehicle seat in said lateral-left direction, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a fourth direction, wherein said fourth direction corresponds to movement of said vehicle seat in said lateral-right direction, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a fifth direction, wherein said fifth direction corresponds to movement of said vehicle seat in said clockwise rotational direction, wherein said step of determining said direction of movement of said at least one multi-positional switch further comprises determining if said direction of movement is in a sixth direction, and wherein said sixth direction corresponds to movement of said vehicle seat in said counter-clockwise rotational direction.
