Abstract

A backpack with a torso length adjustment mechanism is provided. The backpack includes a holder fixedly connected to a bag, a mesh back support having a back mesh contactable to the back of the user and a supporting element for spacedly supporting the back mesh on the holder. The backpack includes a shoulder strap length adjusting mechanism having a force transmitting element for transmitting a force from the holder to the shoulder straps of the backpack. The force transmitting element is lockably movable on the holder between a first position in which a size of the shoulder straps is the largest and a second position in which the size of the shoulder straps is the smallest. The shoulder strap length adjusting mechanism includes a locking mechanism at the holder for releasably locking a movement of the force transmitting element.

Claims

1. A backpack with a torso length adjustment mechanism, comprising:

a holder fixedly connected to a bag;

a mesh back support comprising a back mesh contactable to the back of a user and a supporting element for spacedly supporting said back mesh on said holder;

5. The backpack according to claim 1, wherein said force transmitting element comprises a shoulder strap attachment means for attaching end portions of said shoulder straps directly on said force transmitting element, said backpack further comprising a connecting portion fixedly connecting said end portions at least at a predetermined distance from said shoulder strap attachment means.

6. The backpack according to claim 5, wherein the predetermined distance substantially corresponds to a movement distance of the force transmitting member between said first position and said second position.

7. The backpack according to claim 5, wherein said connecting portion extends in a direction substantially perpendicular to the movement direction of said force transmitting element and comprises a handle portion.

8. The backpack according to claim 7, wherein said connecting portion comprises a fabric sewn to said shoulder straps or wherein said connecting portion is integrally formed with said first and second shoulder straps.
