BACKGROUND In order to improve the passive safety protection capability, some vehicles are provided with a lateral protective air curtain, respectively. The air curtain in a storage state is wrapped and received between the roof rail and the ceiling through the wrapping assemblies. After excitation due to vehicle collision and other reasons, the air curtain is inflated by the gas generator to depart from the roof rail and unfold between a lateral structure of the vehicle and the occupant. The wrapping assembly available in the market usually includes a mounting lug and a wrapping element, wherein the mounting lug is fixed on the roof rail, and the fixed end of the wrapping element is connected with the air curtain and the mounting lug into an integral structure. The free end is connected with the mounting lug after the air curtain is wound around a periphery of the air curtain, so as to wrap the air curtain. In order to restrain the free end of the wrapping element, such wrapping assembly is provided with a complex mating structure on its mounting lug, which leads to a complicated and time-consuming connection process between the free end of the wrapping element and the mounting lug. Moreover, the complex mating structure which is likely to fail, is present with the problem of unstable wrapping form.
