Buffering backpack device for falling protection

The present invention utilizes a backpack body to define an openable accommodation chamber. The accommodation chamber further has an opening on the top end thereof for the communication of the inside and outside thereof. The accommodation chamber utilizes a restricting structure to position an energy absorption band. The energy absorption band is formed of at least a first layer and a second layer that are coincidingly bound. The top ends of the first layer and the second layer extend a first connecting portion and a second connecting portion respectively. The first connecting portion and the second connecting portion divergently protrude from the backpack body via the opening. The first connecting portion is 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 will make the restricting structure release the first layer and the second layer, so that the first layer and the second layer can leave the accommodation chamber via the opening for anti-falling suspension. Accordingly, the present invention just has real improvements, including fine appearance, economic efficiency, and etc.

LOAD ENERGY-ABSORBER

A fiber-reinforced resin load energy-absorber has: a multi-layer woven fabric or laminated woven fabric as a reinforcement base material; a resin as a matrix; slits; binding threads; and reinforcing members. The reinforcement base material has corners formed by bending said reinforcement base material. Slits are provided at least in the portions of the reinforcement base material that form the corners. The binding threads bind each of the woven fabric layers in the multi-layer woven fabric or laminated woven fabric. The binding threads are configured so as to bind each of the woven fabric layers when the multi-layer woven fabric or laminated woven fabric is divided in the thickness direction into at least two woven fabric layers. The reinforcing members are held inside the slits.
