Abstract: A back suspender apparatus includes a back carrier for carrying at least an object thereat and a suspension arrangement. The suspension arrangement includes a back support coupled to the back carrier, and a carrying system which includes two shoulder straps extended from the back support and two resilient straps provided at the shoulder straps respectively for absorbing a bounding force of the back carrier so as to minimize a relative movement of the back carrier with respect to each of the shoulder straps.

Abstract: A backpack includes a pack body, two length-adjustable shoulder straps extended from the pack body for allowing the wearer to wear the pack body at the wearer's back, and a suspension arrangement which includes a resilient unit provided between the pack body and the shoulder straps for absorbing a bounding force of the pack body. Therefore, the resilient unit allows a relative movement of the pack body with respect to each of the shoulder straps but minimizes the relative movement of the pack body by absorbing the bounding force of the pack body. The resilient unit is also arranged for evenly distributing a loading force of the pack body to each of the shoulder straps, such that the resilient unit absorbs the bounding force of the pack body at different directions so as to balance the uneven loading force at the pack body.
