ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a bag, more particularly to a bag having an air-cushioned shoulder strap.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional cushion member is shown to comprise a rubber pad
101
which is made of polyvinyl chloride and which is movable along a shoulder strap
1
of a bag. The rubber pad
101
is elongated, and has two holes
102
formed adjacent to two ends thereof. The shoulder strap
1
passes through the holes
102
in the rubber pad
101
, and the rubber pad
101
is movable to contact the shoulder of a user for cushioning purposes. However, since the rubber pad
101
is relatively hard and lacks sufficient elasticity, the cushioning effect is not satisfactory.
Referring to
FIG. 3
, another conventional cushion member is shown to comprise a soft pad
201
that is sewn on a shoulder strap
2
of a bag. The soft pad
201
has a covering
203
and a sponge or foamed material
202
housed within the covering
203
. Although the soft pad
201
is relatively soft and provides a good cushioning effect, fatigue of the sponge or foamed material
202
will result in poor elasticity of the soft pad
201
after the soft pad
201
has been in used for a period of time.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a bag having a shoulder strap with a cushion member that can provide a good and long-term cushioning effect.
According to the present invention, a bag comprises a bag body, a shoulder strap, and an air pocket. The shoulder strap has two ends attached to the bag body, and an envelope part sewn to the shoulder strap. The air pocket is received in the envelope part to provide a long-term cushioning effect.
