FIELD: transportation.
SUBSTANCE: group of inventions relates to versions of an active buffer for an automotive vehicle and a method of making an inflatable balloon for an active buffer. Exterior trim panel moulded from plastic has a path for welding on inner surface. Plastic element of the expandable balloon has a central attachment section configured to be attached to the vehicle support structure, welded flange along peripheral edge with first surface facing inner surface of trim panel and second opposite surface and folded area between central section of attachment and welded flange. Welding path and welding flange are connected by means of thermal welded seam with closed loop to form sealed chamber. Welding path and welding flange contain complementary surfaces having multiple corrugations that make at least a part of wavy tape welded.
EFFECT: as a result, the greater part of forces at the welded seam during inflation is directed to shift instead of peeling.
