ABSTRACT:
A sports device (10), preferably a snow or water vehicle, has an outer shell (15) which when inflated, forms a support surface (13) underneath and a lying down or sitting surface (20) on top. An inflatable tubular shell (20) with two segments (21, 22) extending crosswise across it is provided in this outer shell (15). The outer shell (15) is formed of a robust fabric which is coated or laminated with plastic. The tubular shell (20), which is in itself separate from the outer shell, is produced from plastic films, preferably without any fabric reinforcement. The outer shell may also be connected to the tubular shell in such a way that they form a single film. The sports device can therefore be produced with optimal materials for the outer shell or the tubular shell, with the result that it has a long service life.
