Japanese Patent JP2012050892
Kind Code:
A
Abstract:

To provide a backpack back-pad having the following properties: it can be easily adjusted to a protrusive object so as to conform to the user's back; when an exterior fabric is embossing-pressed so as to cover a cushioning material, a projection can be satisfactorily adjusted; defect occurs less; examining a position and height of the back-pad projection, which is necessary to become a perpendicular state when it is carried on the back, on each body height provides the back with a moderately close contact with the backpack and with an excellent feeling of touch when the user carries it on the back; a part with no disposition of the cushioning material, because of coming in less contact with the back, provides the back with less feeling of pain; and the user feels the backpack carried on the back light.

An expanded object 6a with larger magnification of foaming is combined with an expanded object 6b with smaller magnification of the foaming in a layer to constitute the cushioning material 6.
