A knee guard device for vehicle occupants comprises a gas bag arranged in the vehicle in a knee well for the vehicle occupant. In its non-inflated state, the gas bag has a length along an imaginary center axis in the axial direction which enables the gas bag to be installed substantially bow-shaped around the knee well in the vehicle. Upon inflation, the length of the gas bag is so reduced that it is tightened between its axial ends to be able to bear radial forces exerted to it by the knees of the occupant.
