Abstract:
A position adjusting system for adjusting a position of a seat in a vehicle and preventing movement of the seat resulting from external forces acting on the seat, the apparatus comprising:a seat track fixable to the vehicle; a motor actuator; a gear train engaged with the motor actuator and the seat track and adapted to cooperate with the seat track to convert movement of the motor actuator into movement of the seat track and the seat; and a non-reversing clutch mechanism having rolling elements including a circular cross-section contacting a race, the non-reversing clutch mechanism being coupled to the gear train and adapted to transfer torque from the motor actuator through the gear train to move the seat upon actuation of the motor actuator, the rolling elements being configured to roll against the race as the motor actuator is actuated, the non-reversing clutch mechanism causing the rolling elements to lock with the race upon torque being applied through the seat track, thereby preventing the external forces acting on the seat from moving the seat relative to the vehicle.
