Abstract

A cooling device for attachment to a helmet includes a fan and an electronics assembly. The fan is operable to draw external air into the cooling device. The electronics assembly is operable to control the rotation speed of the fan based on a speed of movement of a user wearing the helmet with the cooling device attached to the helmet. The cooling device additionally includes an air filter, and a deflector to direct cooled air to a desired one of different regions inside the helmet.

Abstract

A headgear for protecting a user from head injury includes a helmet and a cooling unit. The cooling unit is designed to be attachable to, and detachable from, the helmet by the user during normal use of the headgear. In an embodiment, the cooling unit includes one or more inlets, a fan for drawing in air into the cooling unit via the one or more inlets, a pad to hold moisture to cool the air drawn into the cooling unit to generate cooled air, and an air outlet to direct the cooled air into said helmet.

Abstract

A helmet with a mechanism for cooling comprises an inlet for allowing external air to flow into air pathways in the helmet, and a pad to hold moisture (liquid) to cool the air after the air has entered the helmet via the inlet. The helmet also contains a reservoir to hold the liquid, and a channel from the reservoir to the pad to transfer the liquid for providing moisture to the pad. Flowing air, cooled by the moistened pad, provides cooling to the wearer of the helmet. In an embodiment, a headgear includes a helmet and a cooling unit. The cooling unit is designed to be attachable to, and detachable from, the helmet by the user during normal use of the headgear.
