An inflatable protection device (14) includes a triangular front portion (64) and a main portion (62). The front portion (64) includes a forward edge (72), a rear edge (76), and a bottom edge (74). The front portion (64) is connected to the main portion (62) via a first inflation fluid passage (106) positioned adjacent the bottom edge (74). The front portion (64) includes a plurality of inflatable chambers (120) that have a tapered configuration with a narrow end (134) and an opposite wide end (136) positioned near the bottom edge (74). Inflation fluid is directed into the main portion (62), and the fluid enters the front portion (62) through the first inflation fluid passage (106). The chambers (120) of the front portion (64) when inflated contract in a direction transverse to the length of the chambers and help to tension the device (14) along the length of the device.
