Benefits of technology

[0006]The main objective of the present invention is to provide a backpack with an air cushion that can be inflated to perfectly fit a person's body and improve comfort, whilst minimizing size. The air cushion having a bladder is mounted on one of a back support and straps of the backpack. An inflating device and an air valve are mounted on the bladder for the person to add or remove air, without using their mouth. The air valve on the air cushion is used to empty air and minimize the backpack's size for storage. The inflating device is provided with an inlet valve to add air into the bladder and expand the bladder. Therefore, the bladder can be adjusted to perfectly fit the person whilst leaving their mouth free to partake in strenuous activity and without being too bulky. Also by removing air the backpack can be further reduced in size for storage.

Problems solved by technology

However, thicker sponge increases the backpack size, requiring more space for storage, the elasticity of the sponge reduces with time and the sponge cannot be tailored to individuals.
If various cushioning capabilities are required, the person cannot adjust the cushioning capability of each strap and back support individually.

Embodiment Construction

[0014]With reference to FIG. 1, a backpack with an air cushion in accordance with the present invention comprises a backpack structure (10) and at least one air cushion (20). The backpack structure (10) has a top, a bottom, a back support (11), two straps (12), at least one inner space (13) and a waist belt (14). Each strap (12) has two ends, respectively connected to the top and the bottom of the backpack structure (10). An optional waist belt (14) is connected to the bottom of the backpack structure (10) and are fastened at a person's waist for steadying the backpack structure (10) carried by the person. The at least one inner space (13) may be located at any place on the backpack structure (10) where contacting with the person, so the at least one inner space (13) may be defined in the waist belt (14). In a preferred embodiment, at least one inner space (13) is formed in each respective one of the straps (12) and the back support (11) and may be independent to each other.

Abstract

A backpack has at least one air cushion and a backpack structure. At least one strap is mounted on the backpack structure and the air cushions are mounted onto the strap and backpack structure. The air cushion is mounted with a bladder having an air valve and an inflating device. A person uses the inflating device to add air into the bladder that is then capable of cushioning impacts by the bag and providing a perfect fit to the person. Accordingly, the backpack volume is minimized by pressing the air valve to discard the air and is convenient for storing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a backpack, especially, to a backpack having an air cushion mounted in order to increase comfort for a wearer.[0003]2. Description of the Related Art[0004]A conventional backpack is mounted with a sponge foam for cushioning pressure or friction occurring between a person and the backpack. The thickness of the sponge foam is increased in order to enhance the cushioning capability. However, thicker sponge increases the backpack size, requiring more space for storage, the elasticity of the sponge reduces with time and the sponge cannot be tailored to individuals.[0005]FIG. 6 shows a conventional backpack (4) having a back support (6), a mouthpiece (7), two straps (5) and an air cushion. The back support (6) and the straps (5) are formed with a communicating inner space. The mouthpiece (7) is mounted at the top of one strap (5) for inputting air into the air cushion mounted in the inner spac...
