  • Publication number: 20090078505
    Abstract: A safety device includes a locking mechanism connected to a first portion and a braking mechanism connected to a second portion. The locking mechanism includes at least one pawl and a biasing member urging the at least one pawl into an engaging position. The braking mechanism includes at least one tooth having an engaging surface, and the at least one pawl engages the engaging surface in the engaging position. The engaging position prevents rotation of the first portion in the first direction and allows rotation of the first portion in the second direction. A force of at least 250 pounds on the first portion allows the braking mechanism to rotate thereby allowing the first portion to rotate in the first direction. The braking mechanism is prevented from rotating when the force has been released from the first portion thereby preventing rotation of the first portion in the first direction.
