发明名称 Sports (back) seat
摘要 A sportman's seat or the like made up of a generally rectangular cushion with a cover made of sheet material. A resilient strap which forms a belt for the sportsman is attached to D-shaped rings at each end. Each ring has a tab passing through it. The ends of the tab receive the ends of the cushion cover and are attached to it. The ends of the cushion cover are fixed together entirely across the width of the end except that a space between the cover ends is provided directly under the tab so that air can be expelled from within the cover when the sportsman sits on the seat.
