Abstract
A passenger restraint system for roller coasters, designed to maintain a passenger in an essentially upright posture, the passenger restraint system including a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be movable relative to the fixed column and to be adjustable to the size of the passenger during an embarkation phase. The seat column is coupled to the fixed column by an articulated linkage, and the passenger restraint system further includes a device for balancing the seat column, which balancing device includes a cylinder fixed, at a first articulated end, to the fixed column and, at a second articulated end, to the seat column.

A passenger restraint system for roller coasters, designed to maintain a passenger in an essentially upright posture, the passenger restraint system comprising a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be movable relative to the fixed column and to be adjustable to a size of the passenger during an embarkation phase,
- wherein the seat column is coupled to the fixed column by means of an articulated linkage, and wherein the passenger restraint system further comprises a device for balancing the seat column, which balancing device comprises a cylinder fixed, at a first articulated end, to the fixed column and, at a second articulated end, to the seat column,
- and wherein the cylinder is a hydraulic cylinder that also provides selective locking of the seat column at a locking point.

- the passenger restraint system further comprising:
- a hydraulic cylinder for balancing the seat column and for selectively locking the seat column at a locking point, which hydraulic cylinder is fixed, at a first end, to the fixed column and, at a second end, to the seat column;
- and
- a hydraulic device coupled to the hydraulic cylinder and configured to provide controlled displacement of the hydraulic cylinder, and thus of the seat column, relative to the locking point.
