  • Patent number: 8132514
    Abstract: A lap bar assembly with dual lap bar and grab bar functions. The assembly includes a locking mechanism and a lap bar pivotally mounted to the locking mechanism via a support shaft. The locking mechanism includes a ratchet wheel affixed to the support shaft. A pawl is pivotally supported within the locking mechanism on a pawl support axle parallel to and spaced apart from the lap bar support shaft. The locking mechanism includes a trip cam pivotally attached to the lap bar support shaft. The locking mechanism includes a cam follower that selectively engages the pawl. The locking mechanism is configured to automatically first lock in a first position (or ride position) with the pawl engaging teeth of the ratchet wheel and then second lock in a second position (or released position) with the pawl engaging the ratchet wheel on an uplock surface spaced apart the ratchet teeth.

  • Patent number: 5758582
    Abstract: A restraining device for restraining a passenger on a moving unit includes a passenger body enveloping unit having two side components each having a front end and a back end. The back end of each of the side components is joined to hinges fixed in an upper portion of a back of a seat of the moving unit, and the front end of each of the side components are connected together to form a space for enveloping the passenger. A transverse component rigidly fastened to the passenger body enveloping unit rests against the passenger's thighs when the passenger body enveloping unit envelops the passenger. A lock unit restrains the passenger body enveloping unit after the transverse component has come to rest against the passenger's thighs such that the passenger body enveloping unit envelops the passenger in an area of the passenger's forearms and belly.

  • Patent number: 5586503
    Abstract: A passive passenger restraint system adapted for use with aerial, cable-supported chairlifts includes a passive restraint that is driven by the motion of the chairlift. A seatbelt automatically deploys across the laps of the passengers. The seatbelt restrains the passengers until the end of the trip and then releases the restraint just before unloading the passengers. After unloading, the restraint system automatically resets for the next passengers and the next deployment cycle. A similar passenger restraint system for use in vehicles restrains passengers individually using a shoulder belt and a lap belt.

  • Patent number: 5433153
    Abstract: An amusement track ride system comprises a pair of rails forming a track including a spinning section. A car traveling along the rails includes a chassis, a passenger seat on the chassis, and a plurality of wheel portions situated close to the feet of a passenger in a passenger seat. In the spinning section, the rails extend in a helix along an inner surface of an imaginary cylinder having a central axis, the diameter of the imaginary cylinder being set so that the axis of helical rotation of the car traveling in a spin along the rails passes through the car and is substantially in alignment with the central axis of the imaginary cylinder. The holding device has a shoulder retainer provided at the back rest for holding down the shoulders of the passenger in the passenger seat from above. The retainer is guided by a guide mechanism to be movable in the extending direction of the seat back rest, and locked by a locking mechanism in a position where the retainer abuts against the passenger's shoulders.
