  • Publication number: 20190366882
    Abstract: 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.

  • Publication number: 20160258494
    Abstract: A one-way clutch configured for decoupling an alternator pulley from an alternator hub in a motor vehicle drive system is provided. The one-way clutch includes a ramp plate for non-rotatable connection with an inner circumferential surface of the pulley and rollers in axial engagement with the ramp plate. The rollers are movable along ramped surfaces of the ramp plate between a first position and a second position. The one-way clutch also includes an elastic assembly forcing the ramp plate and rollers into the axial engagement. The elastic assembly axially forces the rollers to transfer torque from the pulley into the hub when the rollers are in the first position. The hub is rotationally decoupled from the pulley when the rollers are in the second position.
