Abstract
A pawl member is formed as an integral structure from a synthetic plastics material, the said member having a pawl tooth extending outwardly from a body part and including a tail for co-operation with an abutment to load the tooth into or out of engagement with a co-operating ratchet formation the member being so designed having regard to its intended context as to operate within the strain limit of the material concerned during normal usage.
Claims6
