Abstract:
A pawl mechanism that reduces the possibility of pawl spring over-compression and damage. The invention can include bumpers disposed near the internal surfaces of the pawls and can space the internal surfaces when the pawls contact one another to reduce the amount of compression applied to the pawl spring. The pawl spring can be inserted into respective cavities on the pawls to further prevent additional compression of and damage to the pawl spring.
