Abstract: A side bolster tilting system of a vehicular seat cushion is provided where a worm portion formed on a rotation shaft of a motor is meshed with a worm gear provided to a female threaded tubular shaft in a lower space of a side bolster, a screw shaft engaged to a lifting member in an idling mode is threaded to an upper portion of the female threaded tubular shaft so that the screw shaft is moved up and down by forward or reverse rotation of the female threaded tubular shaft, and an upper portion of the lifting member is fixed to a support plate for supporting the side bolster. By operation of the motor, the side bolster is moved up and down to provide a driver with convenience when the driver gets on or off, and a leather portion of the side bolster is prevented from being worn out.
