SLEEPING BAG Filed July 29, 1946 wd-MJ Patented Jan. 9, 1951 SLEEPING BAG Karin Briit Ljungberg, Oslo, Norway Application July 29, 1946, Serial No. 686,823 In Norway April 10, 1945 Section 1, Public Law 690, August 8, 1946 Patent expires April 10, 1965 2 Claims. (01. 269.5)

Subject matter of the present invention is a sleeping bag, in the top or upper section of which slits are provided in such way that the getting into and out of the bag is more convenient than in sleeping bags with the now usual single slit in the middle of the top section, and at the same time the opening of the slits provides for an easier movement of the arms without uncovering the shoulder part or the breast and stomach parts.

According to the invention the sleeping bag is in its top or upper section provided with two closeable slits .extending from the face opening so that a flap or leaf is formed between the slits which flap or leaf suitably may be stuffed and serves as a cover for the breast and stomach parts. The slits may be provided with inner slide operated fasteners or with buttons or laces. Upon opening of the slits the flap may be rolled or folded up so that free movement of the arms is obtained. As it is not necessary for this purpose to roll or fold up much of the flap, the shoulders and breast and stomach parts may remain covered. The slits may extend on straight oblique lines from the face opening towards the sides of the sleeping bag whereby slide operated fasteners conveniently may be used for the closing. The slits may also extend parallelly or approximately parallelly in the length direction of the sleeping bag, or they may extend on curved or broken lines, the two last alternatives, being, however, not so suitable for the use of slide operated fasteners.

The drawing illustrates examples of embodiments of the sleeping bag according to the invention in front views. In all figures l is the sleepingbag, 2 the face opening, 3 and 4 the slits and 5 the cord for contraction of the face opening.

In the sleeping bag shown in Fig. 1, the each slits 3 and 4 extend on a straight line from the face opening obliquely towards the sides of the sleeping bagso that a flap 6, serving as cover for the breast and stomach parts is formed between the slits. Slide operated fasteners may here suitably be used for the closing of the slits. In Fig. 2 which shows the upper part of the same sleeping bag, the flap 5 is bent down so as to provide for an opening which is sufficiently great to secure a free movement of the arms. It will be appreciated that the back and the breast and stomach parts hereby will remain well covered.

In order to obtain suitable contraction of the face opening by means of the cord 5, two rings or guides i are arranged at the upper end of the flap 6 on the inner side of the same, through which rings or guides the ends of the lacing cord 5 may lines from the face opening to or near to the sides of the sleeping bag, and Fig. 4 shows the upper part of a sleeping bag in which the slits are extending on broken lines from the lower edge of the face opening at a right angle or approximately right angle to the direction of length of the sleeping bag, and thereupon downwards approximately parallel with the direction of length of the sleeping bag so that a rectangular flap 6 is formed.

I claim:

1. A sleeping bag having in its front panel a permanent opening for the face of the occupant, and two slits provided with closing means and extending from the lower part of the face opening obliquely downward toward the sides of the bag.

2. A sleeping bag having in its front panel a permanent opening for the face of the occupant and two slits provided with closing means and extending from the lower part of the face opening toward the sides of the bag, the bag being provided with a, draw-string around the face opening for contraction of the same and with guide means for the draw-string at the upper edge of the flap formed between the slits.
