Patent attributes
An electrically operated seat slide apparatus includes a lower rail fixed to a floor of a vehicle body, and an upper rail slidably disposed to the lower rail. A seat is connected to the upper rail. A screw shaft is disposed inside the upper rail. A nut is threadedly connected to the screw shaft and connected to the lower rail. A motor is disposed to side of the upper rail. A gear box is fixed to the upper rail to transmit a rotation of the motor to the screw shaft. Additionally, first and second plates are provided for allowing an impact load applied to the upper rail to be directly transmitted to the screw shaft so as to prevent the impact load from being transmitted through the gear box to the screw shaft, and for setting a moving range of the nut.
