Abstract

Shoulder strap of a backpack of leather or other material that holds the backpack on its back, characterized in that the upper strap (1) with the lower strap (2) forms a 120 ° angle, whereby the arm of the wearer is ergonomically embraced.

Description

Standard shoulder straps of backpacks run straight from the top of the bag and are then received at the bottom of adjustable, narrower straps. To improve comfort, these straps are often padded with extra material. This is necessary so that the belt adapts better to the shoulders of the wearer. This adaptation is again necessary because the general admission is just straight, and not ergonomically adapted, which means that the backpacks regularly move from the shoulder when moving and therefore the carrier 'pushed up', so need to be refurbished.

To solve this problem is the object of the approach described in the claims.

Innovation is now to adjust the ergonomics of the backpack on the upper body so that for optimal comfort no strong padding is necessary because the belt automatically adapts to the body by the bend of the belt in the lower area so that the belt is not through the body circumference is 'pulled' from the shoulder.

By bending the belt ( 2 ) at the top of the backpack on the backpack a comfort is achieved, the backpacks with hip belt, but without this, additional belt, making handling much easier and the comfort even with 'simple throw', so when wearing with only one strap continues to be excellent remains.

At the end of this belt (upper belt) is another belt (lower belt) at an angle of about 120 ° ('E' in 1 ) appropriate. This results in the strap of the backpack ergonomically wrapping around the shoulder, even if only one strap is turned over. This lanyard strap is attached to the bottom of the backpack with a buckle strap ( 3 ) connected. Also this buckle strap is mounted in an ergonomic angle (, V ' and , W ' in 3 ). The complete - one-sided - structure is in 4 shown.

The shoulder of the wearer is then in the right triangle between the in 4 shown strap and the backpack back. 5 then shows the complete system on the back of a backpack.
