Abstract
Abstract A motion simulator for vehicle driver training, which includes at least three actuators placed at the vertices of a triangle, connected to at least three connecting points, arranged in a triangle, for the fastening of a platform of a cabin by lever arms, one end of each of these arms being connected to a corresponding actuator by a joint with two degrees of freedom, the other end of one of the lever arms being connected to a point for fastening the platform by the joint with two degrees of freedom, and the other end of the other lever arms being connected, at all times, to one of the other platform fastening points by a joint with at least four degrees of freedom.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
A motion simulator for vehicle driver training, which comprises: at least three actuators placed at the vertices of a triangle, connected to at least three corresponding points, arranged in a triangle, for the fastening of a platform of a cabin by lever arms, one end of each of these arms being connected to a corresponding actuator by a joint with two degrees of freedom, the other end of one of the lever arms being connected to a point for fastening the platform by the joint with two degrees of freedom, and the other end of the other lever arms being connected, at all time, to one of the other platform fastening points by a joint with at least four degrees of freedom.
Claim 2
Dependent Claim
122 words
A motion simulator for vehicle driver training, which comprises: at least three actuators placed at the vertices of a triangle, connected to at least three corresponding points, arranged in a triangle, for the fastening of a platform of a cabin by lever arms, one end of each of these arms being connected to a corresponding actuator by a joint with two degrees of freedom, the other end of one of the lever arms being connected to a point for fastening the platform by the joint with two degrees of freedom, and the other end of the other lever arms being connected, at all time, to one of the other platform fastening points by a joint with at least four degrees of freedom.
