发明名称 Backpack and chair apparatus
摘要 A backpack and chair apparatus with the ability to convert between a balanced backpack and a structurally rigid chair of normal household size. The conversion requires only nominal assembly and effort, does not disrupt the pack load or its accessibility, and requires no tools or separate parts. This advantageously increases the simplicity of pack stowage and the availability of a chair upon demand by those who would otherwise tote a separate chair within or upon a backpack.
