6.3.8.3 Special tools shall not be required to operate the manual release, unless otherwise determined by the ride analysis.
6.3.9 When a latching or locking restraint device is provided, the Patron Restraint and Containment Analysis shall evaluate the need for features such as contours, dividers, bolsters or other forms and shapes that aid in preventing patrons from sliding longitudinally or laterally outside of the restraint area.
6.4 Restra liii Configuration:
6.4. 1 Restraints Required in Kiddie Rides:
6.4.1.1 Where kiddie rides or devices do not provide a fully enclosed compartment (that is, so as to reject a 4 in. diameter sphere at all openings), a latching restraint shall be provided, unless the patron restraint and containment analysis indicate a locking restraint is needed or a restraint is not appropriate (for example, a kiddie canoe ride).
6.4.1 .2 Where kiddie rides or devices provide either latching or locking restraints, the final latching or locking position of the restraint must be adjustable in relation to the patron(s).
6.4.1.3 When a latching restraint is used and a supervising companion is not required, the latching device must be difficult for a child Patron to open by virtue of its design or location, for example, beyond the child Patrons reach envelope or a “push to open” buckle with a release force of 9 lhf (40 N) or greater. A recognized test such as found in FMVSS No. 213 (October 1, 2004 edition, paragraph S6.2. 1) may be used to determine release force.
6.4.2 Restraints Required in or Superi’ision Required frr Rides That Accommodate Both Children Under 48 in. in Height and Adults:
6.4.2.1 Amusement rides or devices intended to accommodate both children under 48 in. in height and adults shall meet the requirements of 6.4.1 or employ other safeguards such as a supervising companion or other means determined by the ride analysis.
6.4.2.2 When a supervising companion is employed to accompany children under 48 in. in height on rides that accommodate both children under 48 in. in height and adults, the supervising companion must either:
(I) Comply with a service proven practice of the operating facility which relates to qualifying supervising companions, or
(2) Meet all the criteria for riding alone and he approximately 14 years of age or older. (See X6.2). A ride analysis may lead to alternate requirements.
6.4.3 Restraints Required Due to Acceleration and Seat
I,zclination:
6.4.3.1 Restraint devices shall be provided in cases where it is reasonably foreseeable that patrons could be lifted or ejected from their seats or riding positions by the acceleration of the amusement ride or device, or by seat inclination, during the ride or device cycle and other reasonably foreseeable situations, for example. the application of emergency brakes or vehicles stopped in inverted positions.
6.4.3.2 The restraint diagram shown in Fig. 2 shall be used as part the patron restraint and containment analysis for determining if a restraint is required, and if required, what type.
