  • Patent number: 5984058
    Abstract: A cushioned braking system for cushioning the impact of a moving vehicle for amusement for children is disclosed. The braking system comprises a double ended air cylinder having a first cylinder end and a second cylinder end. A first head member and a second head member close the first and second cylinder ends, respectively. A first piston rod extends axially outward from the cylinder through the first head member. A first piston is on the first piston rod within the cylinder. A second piston rod extends axially outward from the cylinder through the second head member. A second piston is on the second piston rod within the cylinder. A spring assembly resiliently connects the first piston to the second piston within the cylinder. The spring assembly serves to bias the first and second pistons toward a reference position. The cylinder also has a vent for controlling air flow within the cylinder.
