Abstract: A method of training a golfer to swing a certain golf club upon a desired swing plane angle comprises the step of indicating a swing path guide in front of the golfer. The shape of the swing path guide corresponds to the desired swing plane angle for the golf club and the golfer. In other words, if the golfer swings the club so that the club head creates an arc that corresponds to (or aligns with) the curvilinear swing path guide, the desired swing plane angle will be achieved. A device to train a golfer to swing upon a desired swing plane angle comprises a swing path guide. The shape of the swing path guide corresponds to the desired swing plane angle for a certain golf club and the golfer.

Abstract: The present invention provides an adjustable headband for protective headgear with a ratchet mechanism having different resistances. The adjustable headband utilizes a ring gear assembly having a plurality of radially projecting teeth thereon. Each of the projecting teeth of the ring gear assembly has a first tooth side and a second tooth side which is different from the first tooth side. For example, each tooth of the ring gear assembly preferably has a first tooth angle on the first tooth side and a second, different tooth angle on a second tooth side. A spring assembly having at least one spring tooth projecting radially therefrom is connected to the adjustment knob. The spring assembly is positioned such that the at least one spring tooth meshes with the teeth of the ring gear assembly to provide resistance to the rotation of the adjustment knob.
