The right choice of school backpack has a positive effect on the child's healthy growth and development and minimizes the negative effects associated with carrying a relatively hevy backpack.
However, the backpack must meet essential design criteria that respect the child's anatomy and proper ergonomics.
BASIC ANATOMY OF BACKPACK
A - ADJUSTABLE SHOULDER STRAPS
It is absolutely essential that the shoulder straps and back suspension system are height-adjustable because only this makes it possible to adjust the carrying system to the height of the growing child, allowing it to carry the backpack safely, fitted correctly, and in a way that protects the growing spine.
B - HIP BELT AND LUMBAR SUPPORT
A sufficiently robust and anatomically correctly designed hip belt is the basis and an integral part of the backpack's carrying system. It can transfer up to 70% of the backpack load from the shoulders onto the hips. This dramatically minimizes the compression of the discs and vertebrae in the child's spine, takes the strain from the shoulders, and helps the child to maintain an upright natural posture, enabling it to carry the backpack safely and healthily.
C - REINFORCED AND CONTOURED BACK PANEL
The back panel is one of the most critical parts of the carrying system and central to the performance of the backpack as a whole. It optimally and evenly distributes the weight over the back area, ensures the correct ergonomic interaction between shoulder straps and hip belt, supports the placement and stability of the backpack on the back, and allows it to be carried comfortably and safely.
D - BACKPACK BODY - STORAGE SPACE
The storage space of the backpack is designed to allow heavy objects to be placed as close as possible to the center of the body where it is strongest, all necessary items can be neatly arranged horizontally and vertically in the pack to prevent objects from moving around inside the backpack. The body of the backpack should not be too broad or deep so as not to interfere with the child's freedom of movement.
DETAILED BREAKDOWN AND DESCRIPTION OF THE CARRYING SYSTEM AND BACKPACK STORAGE
ADJUSTABLE SHOULDER STRAPS, BACK PADDING
1 – ANATOMICALLY CORRECT DESIGN OF SHOULDER STRAPS
It ensures even load distributed in both longitudinal and transverse directions.
It optimally follows the anatomy of the child's body – all of its surface area fits the body along the entire length of the strap.
It prevents the straps from slipping off the shoulders and stabilizes the backpack on the back.
The right softness (not too soft, not too stiff) delivers carrying comfort.
2 – HEIGHT ADJUSTABLE CHEST STRAP
Together with the shoulder straps, it provides proper weight distribution of the backpack in the upper part of the body.
It helps to spread the load over the largest possible area of the shoulder straps making full use of their length and width.
It prevents the straps from slipping off the shoulders.
It increases the stability of the backpack on the back and holds it more firmly and safely in place when in motion.
3 – STABILISING WEBBING ON SHOULDER STRAPS
They increase the stability of the backpack on the back and add comfort and safety when in motion.
They help to optimize the load on the shoulder straps and the weight distribution of the backpack.
4 – ANATOMICALLY CORRECT BACKPADDING
It optimally distributes the load over the designated back area.
It makes it easier to carry the backpack comfortably.
It allows high air circulation to the back area, which keeps it well ventilated and reduces sweating on the back.
5 – REFLECTIVE POINTS, SAFETY ELEMENTS
They increase the safety and visibility of the child during darkness and conditions with reduced visibility.
6 – SPINE PROTECTION SYSTEM
It guarantees the backpack fits correctly and sits in a position that supports a healthy development of back.
It allows easy adjustment of the length of the back suspension system as the child grows, thus ensuring optimal settings respecting the anatomy of the back and the required ergonomics.
HIP BELT, LUMBAR PADDING
7 – FUNCTIONAL BUCKLES MADE OF QUALITY MATERIALS
They are easy to operate even with the small, clumsy fingers of a child and are practical, functional, and durable.
8 – SUFFICIENTLY ROBUST ANATOMICALLY CORRECT DESIGN OF THE HIP BELT
It is able to takes up to 70% of the backpack's weight from the shoulders and spreads it along the much stronger hip area.
It optimally follows the anatomy of the child's hips – all of its surface area fits the body along the entire length of the belt.
Together with the stabilizer straps, it keeps the backpack firm and stable in the correct position, and ensures it can be carried safely.
The right softness (not too soft, not too stiff) ensures stability as well as comfort.
9 – ANATOMICALLY CORRECT LUMBAR PAD
It optimally distributes the load over the designated area of the lower back.
It delivers comfort carrying of the backpack.
10 – STABILISER (BALANCE) STRAPS ON THE HIP BELT
They increase the stability of the backpack, minimizing side-to-side movement when walking, and ensuring that the pack can be carried more safely.
They help optimize the load distribution on the hip belt and thus the weight distribution of the backpack.
11 - PASSIVE REFLECTIVE SAFETY POINTS
They increase the safety and visibility of the child in the dark and in conditions with reduced visibility and are positioned on the front, sides and back of the pack.
BACKPACK BODY - STORAGE SPACE
12 – REINFORCED PADDED 3D CHAMBER ON THE INSIDE OF THE BACK PANEL
Heavy school and exercise books in A4 format can be carried as close as possible to the center of gravity of the child's body where it is strongest.
All heavy schoolbooks and items are firmly kept in place and stopped from shifting around in the backpack, which adds to the stability of the backpack on the back, so that it is safe to carry while in motion.
It helps to keep things organized in the main compartment of the backpack.
It protects the inserted items from damage and has replaced the formerly used C4 cardboard.
13 – REINFORCED PADDED POCKET ON THE 3D CHAMBER
Safe storage for exercise books, schoolbooks and items in A5 size.
Books and items are firmly kept in place and stopped from shifting around, and it also helps to keep things organized in the backpack.
It protects inserted items from damage.
14 – MESH POCKETS AT THE TOP OF THE MAIN CHAMBER
They allow the use of the space in the upper part of the main chamber, making optimal use of the entire backpack volume.
They help to keep things organized in the backpack and protect them from damage.
REINFORCED AND CONTOURED BACK PANEL
A – BACK PANEL FLEXIBLE REINFORCEMENT MADE FROM PRE-CURVED FLEXIBLE STEEL ROD
It strengthens and supports the anatomically correct shape of the back panel, following the natural shape of the spine.
It gives the back panel the necessary rigidity as well as flexibility to correctly distribute the weight of the backpack and, at the same time, provides enough flexibility so as not to restrict the movement of the child's body.
B – HDPE (POLYETHYLENE) BACK PANEL SHEET
This provides overall rigidity to the back panel, lumbar support, and the rest of the backpack.
It distributes the weight of the backpack most effectively over the designated area of the back panel. Together with the shoulder straps, back panel, hip belt, and lumbar pad, it underpins the overall functionality of the back system.
The back panel supports the overall shape of the backpack's storage space.
C – POLYETHYLENE / EVA FOAM PERFORMANCE
On the back panel, it distributes the backpack's weight evenly over the entire area.
On the shoulder straps and hip belt, it effectively spreads the load over their maximum surface areas, making efficient use of their contoured shape and improving carrying comfort.
It increases carrying comfort at the back and lumbar pad area.
D – POLYURETHANE FOAM
It increases the comfort of carrying the backpack.
It optimally spreads the load and weight of the backpack on the child's body.
It acts as a cushioning layer when walking, running, and jumping.
