Abstract
Abstract The Seat Base Motion Controller provides automated control of seat motion for seat systems employed in providing combined visual and motion experience for patrons in amusement rides and the like. Occupant safety features are integrated within the seat motion control system and centralized control of multiple motion bases is accomplished. Motion control of the seat bases is responsive to a position signal input coordinated with a visual presentation viewed by the patrons. Self contained power systems for the actuation means of the seat base allows sizing of an entertainment threater to accommodate anticipated audiences. Independent control and operation of each motion base precludes the need for shutting down the entire theater if a fault exists in one motion base or the safety systems on that motion base are activated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
130 words
A motion seat base for use in combination with a visual presentation for increased realism in an entertainment experience comprising: a frame for supporting at least one seat; a plurality of actuating means which are independently positionable for imparting motion to the frame; a means for providing actuation signals syncronized with the visual presentation; a control means connected to the actuating means and responsive to the actuation signal providing means for controlling the position of each of the actuating means to impart motion; a position sensing means connected to each actuating means for sensing the position of the actuating means and providing a feedback to the control means; and, a safety system connected to the seat and the control means for deactivating the actuating means if an unsafe condition exists.
Claim 2
Dependent Claim
130 words
A motion seat base for use in combination with a visual presentation for increased realism in an entertainment experience comprising: a frame for supporting at least one seat; a plurality of actuating means which are independently positionable for imparting motion to the frame; a means for providing actuation signals syncronized with the visual presentation; a control means connected to the actuating means and responsive to the actuation signal providing means for controlling the position of each of the actuating means to impart motion; a position sensing means connected to each actuating means for sensing the position of the actuating means and providing a feedback to the control means; and, a safety system connected to the seat and the control means for deactivating the actuating means if an unsafe condition exists.
Claim 3
Dependent Claim
93 words
A motion seat base as defined in claim 1 wherein the safety system comprises: a seat belt system located at each seat and having a latch for connection to secure a seatbelt; means for detecting a patron seated in the seat; and, means for sensing when the latch is connected; and wherein the control means includes: means for comparing the detecting means and the sensing means to verify that when a patron is seated and the latch is connected; and, means for disabling motion of the actuation means responsive to the comparing means.
Claim 4
Dependent Claim
29 words
A motion seat base as defined in claim 2 wherein the seat belt system further comprises means for locking the latch once connected to prevent disconnection by the patron.
Claim 5
Dependent Claim
48 words
A motion seat base as defined in claim 3 wherein the seat belt system further comprises a means for tensioning the seat belt to retract the seat belt when unlatched and maintain a tight fit across the patron's lap when latched, and means for locking the tensioning means.
Claim 6
Dependent Claim
26 words
A motion seat base as defined in claim 4 wherein the seat belt system further comprises means for indicating that the latch locking means is locked.
Claim 7
Dependent Claim
49 words
A motion seat base as defined in claim 5 wherein the control means further comprises means for energizing the latch locking means, and wherein the control means is responsive to the latch lock indicating means to prevent the actuating means from producing motion when the latch is not locked.
Claim 8
Dependent Claim
26 words
A motion seat base as defined in claim 4 wherein the seat belt system further comprises means for indicating that the tensioning locking means is locked.
Claim 9
Dependent Claim
52 words
A motion seat base as defined in claim 7 wherein the control means further comprises means for energizing the tensioning locking means, and wherein the control means is responsive to the tensioning lock indicating means to prevent activation of the actuating means to produce motion when the tensioning means is not locked.
Claim 10
Dependent Claim
34 words
A motion seat base as defined in claim 8 wherein the control means is responsive to the detecting means to energize the tensioning locking means when a patron is not present in the seat.
Claim 11
Dependent Claim
34 words
A motion seat base as defined in claim 1 wherein the actuating means comprise hydraulic cylinders controlled by solenoid actuated valves and the motion seat base further comprises a self contained hydraulic power unit.
Claim 12
Dependent Claim
43 words
A motion seat base as defined in claim 10 wherein the control means includes means for generating a pulse width modulated signal for each solenoid actuated valve responsive to the actuation signal providing means and the solenoid actuated valves are hydraulic solenoid valves.
Claim 13
Dependent Claim
85 words
A motion seat base as defined in claim 11 wherein the generating means comprises: means for receiving the feedback from the position sensing means to determine the actual position of the actuating means; means for comparing a desired position determined by the actuation signals to the actual position to establish a position difference; means for calculating the required pulse width modulated signal to achieve the desired position based on the position difference; and, means for transmitting the pulse width modulated signal to the valve solenoids.
Claim 14
Dependent Claim
195 words
A motion seat base as defined in claim 12 wherein the control means comprises: a central controller responsive to an operator console having a manual activation switch, a manual emergency stop switch and means for displaying status of the seat safety system, the central controller further responsive to the actuation signal providing means and providing start, stop, and position signals; a motion base controller adapted for activating a means for locking a latch for connection to secure a seatbelt and the generating means, and the motion base controller is responsive to a means for detecting a patron seated in the seat, a means for sensing when the latch is connected, a means for indicating that the latch locking means is locked, and the start, stop and position signals; and the motion base controller further providing a seat status signal; means for communicating the start, stop, and position signals from the central controller to the motion base controller and the seat status signal from the motion base controller to the central controller; and, means for transmitting the seat status signal from the central controller to the seat safety system status displaying means of the operator console.
Claim 15
Dependent Claim
59 words
A motion seat base as defined in claim 13 further comprising: a means for tensioning the seat belt; a means for locking the tensioning means; and, a means for indicating that the tensioning locking means is locked, wherein the motion base controller is further responsive to the tensioning lock indicating means and adapted for activating the tensioning locking means.
