AI Technical Summary
Technical Problem
The existing rotating device for vehicle seats experiences displacement of the seat position relative to the vehicle body due to clearance between the inner and outer rings, leading to an unstable ride experience for passengers.
Method used
The rotating device positions the first and second drive gears relative to the driven gear at an angle other than 180 degrees, ensuring consistent seat displacement direction and incorporates a control system to manage gear collisions and backlash during rotation stops.
Benefits of technology
This configuration provides a more stable and comfortable ride by maintaining consistent seat displacement and reducing gear collisions, allowing for the use of less robust materials and enabling device miniaturization.

Abstract
The present invention provides a rotating device that eliminates discomfort to occupants when a vehicle seat starts rotating and when it stops. [Solution] The rotating device (100) rotates a vehicle seat (70) relative to the vehicle body (F) in a pivoting direction and includes a rotating member (10) having an inner frame (12) and an outer frame (14) assembled in a manner that allows them to support each other on the same axis and rotate relative to each other; a driven gear provided on one of the inner frame (12) or the outer frame (14); a first drive gear and a second drive gear fixed to the other of the inner frame (12) or the outer frame (14) and meshing with the driven gear; a first motor (41) for rotating the first drive gear; and a second motor (42) for rotating the second drive gear. The first drive gear and the second drive gear are positioned relative to the driven gear such that the angle between a first straight line connecting the central axis of the driven gear and the first axis of the first drive gear and a second straight line connecting the central axis and the second axis of the second drive gear is an angle other than 180 degrees.
