Abstract
A helmet shell assembly wherein a helmet shell is provided with a covering of normally flat thermoplastic material which is disposed on the shell in such a manner as to have a minimum number of seams. The assembly is made by inserting a support member (44) into a helmet shell (12), positioning the shell and support into a cavity (50) of a forming fixture (46), then draping a sheet of softened thermoplastic material (16) [which is supported by a frame (48)] over one side of the shell, vacuum forming the sheet (16) about the side of the shell, and then trimming the sheet after it has set. The other side of the helmet shell is then covered by repeating the above steps, and then a tape is applied over the length of the helmet to cover the exposed seams. A protective coating and an edge roll may then be applied. The shell may initially be covered with a surface finish.
