Description

Technical Field

[0001] This utility model relates to a simple device for covering a backpack. Background Technology

[0002] Currently, seats are an important component of automotive interiors. During the assembly of seat back assemblies, it is necessary to wrap the steel frame with the composite material and then fix the outer skin to the top of the composite material for the wrapping operation. Since the front and rear corners need to be aligned during the wrapping process, the seat back angle needs to be constantly adjusted. The traditional method requires two operators to work together, which is time-consuming, labor-intensive, and inefficient. At the same time, due to different fixing points, it is difficult to exert force during the wrapping process, resulting in phenomena such as the outer skin floating and wrinkles, which affect product quality.
