US 11,517,776 B2 · Buffering backpack device for falling protection

Abstract

A backpack body has an openable accommodation chamber having a top opening. The accommodation chamber utilizes a restricting structure to position an energy absorption band. The energy absorption band includes a first layer and a second layer that are coincidingly bound. The top ends of the first and second layers extend first and second connecting portions respectively. The first and second connecting portions divergently protrude from the backpack body via the opening. The first connecting portion is configured for coupling with a safety harness, while the second connecting portion is for coupling with an anti-falling device. When the user falls, the falling makes the restricting structure release the first and second layers, so that the first and second layers leave the accommodation chamber via the opening for anti-falling suspension. Accordingly, the present invention has real improvements, including fine appearance, economic efficiency, and etc.
