Abstract
An anti-rollback apparatus includes a lock arm, a rod, a pawl, a wheel, and a one-way bearing. The rod member is pivotably coupled to the lock arm and the pawl and one-way bearing are coupled to the rod member. The pawl is shaped to selectively engage teeth on a an anti-rollback plate. The wheel is configured to roll on a surface of the anti-rollback plate. The one-way bearing couples the wheel to the pawl. The one-way bearing allows the wheel to rotate freely in a first direction and locks the wheel in relation to the pawl when the wheel rotates in a second direction to force the pawl to engage the teeth.
