Omen Snow Helmet

The Omen Ski Helmet 2005
This model was early in my career and I was mechanical lead on a snow helmet for the first time.

Vented helmet with ABS plates riveted onto a PC cap. Two slider systems, front and rear.
Industrial Designer Hilgard Muller
Manufacturing Engineer: Raul Hoeptner
Mechanical Tasks on this project
o Vent slider open/close system: includes sliders, slider actuation components, button
o Riveted APS plates (covers)
o Goggle strap clip and attachment method
o Ear pad support structure and snap method
o Final CAD release package and corrections during development

This project had difficulties just prior to the need for sales samples. The sliders were not functioning well so the team deconstructed all the sales samples and reworked them so that they would function at the trade show. See the picture of us working on them in one of the pattern shop rooms in Santa Cruz.

Giro Omen Snow Helmet, this view shows the two buttons which actuate the sliders and vent closures.
In this photo the white color is the polycarbonate shell. The metallic blue is the injection molded cover panels which are riveted to the white shell. The sliders are under the covers and actuated by the buttons.
One of the pattern shop rooms in the old Bell/Giro building. The team is working on a slider/cover retrofit on sales samples. That's me on the far right.
Giro Omen Helmet. This is a more complete picture including retention system and ear pads. The finer details of shape and form are Hilgard's design.
