摘要

The device has a bladder assembly (20) including bladders (21,22), and a hose connected between the bladders. The bladder (22) has an outgoing hose extending from a compressible unit (10) connected to an inlet of the bladder (21). The compressible unit forces air to inflate the bladder (22) to absorb the load. A valve connected to the outgoing hose controls volume of air flowing in the outgoing hose.
