| Abstract: |
The specification discloses a head covering in the form of a helmet of unique construction adapted for wear indoors by persons of either sex during leisure time or while sleeping. The helmet is multi-layered, with an outer layer of lambs wool, long-haired fur or other similar heat insulating material and an inner layer of woven fabric. The helmet is constructed so as to be supported at each side on the bridge of the wearer's ears and in front on the wearer's brow so as to provide an air space between the crown of the wearer's head and the inside of the helmet. The rear portion of the helmet has an essentially inverted V-shaped opening for ventilation of the space above the wearer's head within the helmet by ambient air. The two extremities of the rear portion of the helmet are held snugly to the back of the wearer's neck by an adjustable strap of elastic material connecting them. Additional tie strings sewn to the rear extremities of the helmet serve, when tied, to insure clearance between the rear portion of the helmet and the head of the wearer, notwithstanding variations in the wearer's head size.

What I claim is:
1. A helmet comprising a relatively stiff crown portion and a rear portion conforming generally to the contour of the human head and consisting of laminate material, the crown portion having a frontal edge adapted to seat low on the brow of the wearer and to arch forwardly away therefrom and having at each side an ear bridge - supported side edge that extends in a substantially straight horizontal line backwardly from the frontal edge, said crown having a vertical height such that the ear bridge-supported side edges are adapted to support the crown portion in an elevated position providing a space within the crown portion above the top of the head of the wearer, the said rear portion having a generally inverted V-opening extending into said crown portion via which ambient air may enter and circulate within the said space within said crown portion while on the head of a wearer, and tensioning means extending across said V-shaped opening and adapted to rest on the back of the neck of the wearer to secure the helmet in position.
