Abstract
A motion seat for use in a vehicle motion simulator comprises a seat back, a seat pan, a first actuator coupled to a linkage assembly located on one side of the seat pan, a second actuator coupled to an identical linkage assembly on the other side of the seat pan, and a third actuator coupled to a linkage assembly on the aft end of the seat pan, wherein the first and second actuators are effective to independently produce roll right and roll left motion of the seat pan while collectively creating upward and downward heave motion of the seat pan and the third actuator is effective to create surge motion of the seat pan.
Claims24
A motion seat, comprising:
- a back pan;
- a seat pan having a forward end, an aft end and opposed left and right sides;
- a first aft pivot and a second aft pivot each located on one of said opposed left and right sides of said seat pan, each of said first and second aft pivots being connected to said seat pan by an aft link;
- a first forward pivot and a second forward pivot each located on one of said left and right sides of said set pan, each of said first and second forward pivots being connected to said seat pan by a forward link;
- a first connecting link extending between said first aft pivot and said first forward pivot, and second connecting link extending between said second aft pivot and said second forward pivot;
- a first actuator coupled to said first aft pivot and a second actuator coupled to said second aft pivot, said first and second actuators being effective to move at least one of said respective first and second aft pivots in such a way that said seat pan undergoes at least one of upward heave, downward heave, roll right and roll left motions.
A motion seat, comprising:
- a back pan;
- a seat pan having a forward end, an aft end and opposed left and right sides;
- a first actuator coupled to said left side of said set pan, said first actuator being movable from a neutral position to a first position and to a second position, said left side of said seat pan being movable in a roll left direction in response to movement of said first actuator toward said first position;
- a second actuator coupled to said right side of said set pan, said second actuator being movable from a neutral position to a first position and to a second position, said right side of said seat pan being movable in a roll right direction in response to movement of said second actuator toward said first position;
- said first and second actuators being simultaneously movable toward said first position to move said seat pan in an upward heave direction, and said first and second actuators being simultaneously movable toward said second position to move said seat pan in a downward heave direction.
A motion seat, comprising:
- a back pan;
- a seat pan having a forward end, an aft end and opposed left and right sides;
- an aft pivot coupled to said aft end of said seat pan;
- an aft actuator coupled to said aft pivot, said aft actuator being movable from a neutral position to a first position and to a second position, said aft pivot being effective to move said seat pan in a forward direction in response to movement of said aft actuator toward said first position and said aft pivot being effective to move said seat pan in an aft direction in response to movement of said aft actuator toward said second position.
