US Patent 11407336 Stamped splined locking mechanism for rotating automotive seat bracket

A vehicle seat rotates in response to activation of an electric motor. The electric motor is part of a non-back-drivable mechanism such that it acts to lock the seat in position. The seat mechanism is assembled from stamped components for efficient manufacturing. A bracket includes integrally formed gear teeth which mesh with gear teeth driven by the electric motor. The bracket is held between two stamped parts using four-point angular contact ball bearings. The races of the ball bearings are stamped into the respective stamped parts.
