  • Cap
    Patent number: 4551859
    Abstract: A cap intended for cold or cool weather use, particularly useful in sports such as skiing, but not limited thereto. The cap is provided with integral ear flaps. A particular characteristic is that the ear flaps are self-stowing in the interior of the cap; that is, they tend to retract into the cap and out of the way without intevention. When in the downward operational position, the ear flaps tend to fit snugly around the ears of the wearer without the necessity of additional ties. An elongated securing of one edge of the ear flaps and the provision of a stiffener layer in the ear flaps combine to produce the spring-like lever-like action resulting in these advantages.
