POSITION ADJUSTING MECHANISM FOR SEAT OF VEHICLE

PROBLEM TO BE SOLVED: To provide a seat position adjusting mechanism for adjusting the position of a seat for a vehicle, and preventing movement of the seat resulting from external forces acting on the seat. SOLUTION: The mechanism includes a seat track fixable to the vehicle, a motor actuator, and a gear train 58 engaged with the motor actuator and the seat track to convert movement of the motor actuator into the relative motion between the seat track and the seat. A non-reversing clutch mechanism 68 is coupled with 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 but locking 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.
