Passenger restraint systems are provided. The restraint systems can include: a passenger seat supported by a frame; a restraint bar pivotably attached to the frame; and at least one piston operably engaged between the restraint bar and the frame. Restraint system pistons are provided. The pistons can include: a central chamber housing a piston head and rod; a fluid reservoir in fluid communication with the central chamber; and at least one electromechanical valve operable between an open and a closed position. Methods for restraining a passenger within a seat are also provided.

Methods for restraining a passenger within a seat are also provided.

Manually operable piston assemblies are provided that can include a piston head within a cylinder, the piston head separating fluid in the cylinder to define rod-side fluid and head-side fluid. The piston assembly can be configured to operate in at least six positions, including but not limited to a first position of locking retract static; a second position of locking retract extend flow; a third position of locking retract flow; a fourth position of locking extend static; a fifth position of locking extend retract flow; and a sixth position of locking extend flow. Manually operable piston assemblies are also provided that can include a piston head within a cylinder, with the piston head separating fluid in the cylinder to define rod-side fluid and head-side fluid. The manually operable piston assembly can further be configured to operate in at least six positions that include a first position of locking extend static; a second position of extend movement flow; a third position of manual override retract flow; a fourth position of manual override extend flow; a fifth position of locking retract static; and a sixth position of retract movement flow.

Methods for operating a manually operable piston are also provided. The methods can include applying pressure to retract the piston rod and allow head-side fluid to pass through piston head passageway and mix with rod-side fluid. Methods for operating a manually operable piston can also include applying pressure to extend or retract the piston rod and allow head-side fluid to pass through at least one valve and mix with rod-side fluid.

A ride vehicle system includes a ride vehicle including a seat configured to accommodate a passenger, a restraint system of the ride vehicle, where the restraint system includes a restraint configured to secure the passenger within the seat, and a forced air system of the ride vehicle, where the force air system is configured to generate an air flow, direct the air flow internally through the restraint, and discharge the air flow toward the passenger via a discharge port of the restraint.

A vehicle configuration wherein the center of mass of the vehicle is approximately superimposed upon the passenger and driver centers of mass when seated within the vehicle. An occupant's center of mass can be approximated using a standard center of mass position approximation, or a combination of any number of standard center of mass position approximations. The vehicle's center of mass can be approximately superimposed upon the occupant's center of mass in at least the longitudinal and vertical directions.

A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.

A ride vibration system includes a rider support feature coupled to a ride vehicle and accessible to a rider positioned in the ride vehicle. The system includes a vibrator with a motor that rotates an eccentric mass to generate vibrations. The vibrator is at least partially integrated with the rider support feature and transfers the vibrations to the rider support feature. An input device receives a vibration intensity selection. A controller couples to the vibrator and to the input device. The controller receives the vibration intensity selection and controls the motor to control an intensity of the vibrations.

A support frame assembly configured to strengthen an upper frame portion of a frame of a vehicle, comprising a first frame member having a first end and a second end, and a second frame member having a first end and a second end, wherein both the first ends of the first and second frame members are configured to couple to a front half of the frame and the second ends of the first and second frame members are configured to couple to the front half of the frame to strengthen the upper frame portion, at least one of the first and second ends of each of the first and second frame members including at least one mechanically coupled joint configured for coupling each of the first and second frame members to the front half of the frame.

A ride vehicle for an amusement park includes a restraint system. The restraint system includes a first conformable component configured to be disposed over a first lower portion of a guest's body. The restraint system further includes a behind-the-knee component configured to be disposed behind a leg of the guest. The restraint system additionally includes a linkage mechanism configured to move the first conformable component, the behind-the-knee component, or a combination thereof, to secure the restraint system to the guest.
