Abstract:
1. A buffering cushion with a suspending layer hung between inward-bent air columns, the buffering cushion being made of at least two outer films and comprising: a first buffering member, including a plurality of said air columns arranged abreast, wherein each said air column has each of two opposite sides thereof formed with a heat-seal line that binds the two outer films together, and has each of two opposite ends thereof formed with a joint through heat sealing; a second buffering member, extended from one side of the first buffering member and including a plurality of inflatable wall columns that are connected to the air columns of the first buffering member via the joints, so that the second buffering member is allowed to be bent inward against the joints, and the second buffering member has one side opposite to the first buffering member formed with a connecting heat-seal border for connecting the inflatable wall columns through heat sealing; a third buffering member, extended from one side of the first buffering member opposite to the second buffering member and including a plurality of inflatable wall columns that are connected to the air columns of the first buffering member via the joints, so that the third buffering member is allowed to be bent inward against the joints, and the third buffering member has one side opposite to the first buffering member formed with a connecting heat-seal border, in which at least one air channel is arranged between the first buffering member and each of the second and third buffering members so that an inflating air flow is allowed to flow through the first, second and third buffering member; and the suspending layer, connecting the connecting heat-seal borders of the second buffering member and the third buffering member, and forming together with the second buffering member and the third buffering member an accommodating space opened outward, wherein the suspending layer has each of two sides thereof provided with an extended portion, with one said extended portion integratedly extended from the connecting heat-seal border of the second buffering member and the other said extended portion integratedly extended from the connecting heat-seal border of the third buffering member, and the two extended portions are heat sealed together to form a suspending portion substantially located at a center of the accommodating space, whereby the suspending layer serves to carry an external object, and forms together with the first, second and third buffering members a cushion body of the buffering cushion, for providing the external object with buffering protection, in which one end of the cushion body is formed with an end opening communicated with the accommodating space; wherein each of the second buffering member and the third buffering member has a plurality of aligned bent sections formed through heat sealing, and a vertical wall is formed between the connecting heat-seal border of each of the second buffering member and the third buffering member and the corresponding bent sections, so that the vertical walls are allowed to be bent in toward the accommodating space against the bent sections, in which each said vertical wall comprises plural said inflatable wall columns, and in which what is between the bent sections of each of the second and third buffering members and the joints of the first buffering member is defined as a supporting portion, and each said vertical wall has a height smaller than a height of the supporting portion.
