Patent ID: 8608475

Claim:
A motion simulator for transmitting motion with respect to a floor as a function of motion signals associated to a video output, comprising: a seating portion for accommodating a viewer viewing the video output, the seating portion comprising at least a seat, a backrest and armrests on opposite sides of the seat, the armrests each defining an inner cavity; and at least two actuators, each of the actuators having a housing and an output shaft interrelated by a degree of freedom, each of the actuators having a motor in the housing fixed to the seating portion without any degree of freedom between the motor and the seating portion, and a free end of the output shaft oriented toward the floor for displacing the output shaft with respect to the housing along the degree of freedom as a function of actuation from the actuators in relation to the motion signals such that the free end of the output shaft pushes against the floor to lift the seating portion; wherein the housing and the motor of at least two of the actuators are secured to the seating portion and are received and fully housed in the inner cavity of a respective one of the armrests, and the free end of each of the output shafts of the actuators permanently support the motion simulator directly on the floor with the free ends of the output shafts not being connected to one another, whereby the seating portion is movable along at least two degrees of freedom as a function of actuation from the actuators.
