Abstract: The helmet of the present invention comprises an outer and inner shell having a top, a front, a rear, and left and right sides corresponding to wearer's crown, face, rear and left and right sides, respectively. The front of the helmet has an enlarged view window that exposes at least a portion of the wearer's face. The view window has an upper rim, lower rim, right rim, and left rim. The lower rim extends from the front of the helmet to about the auditory canal. The upper rim is separated from the lower rim and loosely tracks the path of the lower rim. The upper rim is connected to the lower rim on both the left and right sides by left and right rims, respectively. A step is formed in the lower rim as it proceeds towards the back of the view window. This increases the wearer's view of the road. The upper rim is connected to the lower rim on both the right and left sides by the right and left side rims, respectively. The side rims have a straight slant that extends backwards from bottom to top.

Abstract: A helmet sock for protecting a helmet wearer from cold weather conditions while snowmobiling, motorcycling, skiing and other like activies. The helmet sock attaches to the outside lower perimeter of a helmet by a strip of hook and loop material such as Velcro-type material. A strip of Velcro-type material is secured to the outside lower perimeter of the helmet by pressure sensitive adhesive and a corresponding strip is attached to the upper inside circumference of the sock. The sock comprises an adjustable flap at the rear of the helmet for making a secure airtight fit on the helmet. The sock prevents outside air from penetrating and retains the body heat of the wearer in addition to stopping snow and wind from entering the bottom of the helmet. When the weather temperature rises, the sock may be rolled up and stretched around the bottom of the helmet or simply pulled off the perimeter of the helmet.

Abstract: A comfortable, self-adjusting, protective helmet made from a process of insert molding.

Abstract: A welding helmet includes a connector for connecting the head gear and the protective shell and is comprised of an external finger knob allowing for user adjustment of the friction developed by the connector, a conical pivot stop having a conical surface, a strap member having a matching conical surface with the frictional forces being developed between these two conical surfaces, and a bolt which joins the parts of the connector and mounts them between the head gear and shell. A guide pin and guide slot in the stop and strap member control and guide the movement between these two parts as the shell is moved with respect to the user's head. A locator pin in the stop is inserted into one of a series of holes in the helmet to locate the angular orientation between the stop and the helmet, and thereby helps to fix the limits of relative movement between the shell and the user's head.

Abstract: A helmet having substantially semi-looped pull members and the like which are mounted on inside pads and used to pull out the inside pads from a head protecting cap portion while the helmet is worn on the head of a helmet wearer, and a method of removing the helmet. According to this helmet, the inside pads are pulled out from the head protecting cap portion by pulling the pull members with fingers or the like, thereby removing the head protecting cap portion from the head of the helmet wearer with a relatively small force.
