Definitions

• the present invention relates to carrying aides, and more particularly, to ergonomic backpacks.
• the human vertebral column also called the backbone, spine, or spinal column, consists of a series of thirty-three irregularly shaped bones, called vertebrae. These thirty-three bones are divided into five categories depending on where they are located in the backbone.
• the first seven vertebrae are called the cervical vertebrae. Located at the top of the spinal column, these bones form a flexible framework for the neck and support the head. The next twelve vertebrae are called the thoracic vertebrae. These bones move with the ribs to form the rear anchor of the rib cage. Thoracic vertebrae are larger than cervical vertebrae and increase in size from top to bottom. After the thoracic vertebrae, come the lumbar vertebrae. These five bones are the largest vertebrae in the spinal column. These vertebrae support most of the body's weight and are attached to many of the back muscles. The sacrum is a triangular bone located just below the lumbar vertebrae.
• the sacrum forms the back wall of the pelvic girdle and moves with it.
• the bottom of the spinal column is called the coccyx or tailbone. It consists of three to five bones that are fused together in an adult.
• the spine When looked at from the side, the spine forms four curves. These curves are called the cervical, thoracic, lumbar, and pelvic curves.
• the cervical curve is located at the top of the spine and is composed of cervical vertebrae.
• the thoracic and lumbar curves composed of thoracic and lumbar vertebrae respectively.
• the final curve called the pelvic or sacral curve is formed by the sacrum and coccyx.
• the vertebral column serves several other important functions. It helps to support the head and arms, while permitting freedom of movement. It also provides attachment for many muscles, the ribs, and some of the organs and protects the spinal cord, which controls most bodily functions.
• the instant invention comprises a combination longitudinal curved-shaped back support, with a plurality of padding at predetermined positions, that alleviate pressures upon the back of a user while bearing a load of matter carried within a backpack.
• two shoulder straps mounted to a rear wall include gel supports to disperse pressure over the shoulders and neck area of the user.
• One chest strap is fixed to each of the shoulder straps that may be adjusted to the center of the chest, therefore placing the weight of the backpack at the center of the body to relieve direct pressure to the user's vertebral column.
• the instant invention is an ergonomic backpack that comprises a main compartment.
• the main compartment has at least one access wall that has a first substantially inverted U shape, a rear wall and a base wall to define a substantially hollow first cavity.
• the access wall has a first zipper as a means to access the first cavity.
• An elongated longitudinal curved-shaped back support is interiorly mounted within the rear wall and has curvature areas in between first and second ends.
• One curvature area complements and supports thoracic vertebrae of a human vertebral column, and the other curvature area complements and supports a lumbar vertebrae of the human vertebral column.
• a pad comprises dorsal padding and lumbar padding that outwardly protrude from the rear wall of the main compartment.
• the dorsal padding and the lumbar padding are ergonomically designed to contour the back and shoulders of a human.
• the dorsal padding and the lumbar padding are of a sufficient predetermined thickness to dispense pressure upon the human vertebral column.
• the pressure results from a force established by a weight of matter housed within the first cavity, or otherwise secured upon the main compartment.
• a strap assembly is fixedly secured to the main compartment and comprises shoulder straps, chest straps, and waist straps.
• the shoulder straps also include padding that dispenses the pressure resulting from the force defined above.
• the shoulder straps have the chest straps fixed thereon.
• the chest straps may be adjusted to a center chest of the human to align the main compartment with the human vertebral column.
• the chest straps have first cooperative locking means to adjustably mount thereon and to fixedly secure the chest straps around the center chest of the human.
• the waist straps have second cooperative locking means adjustably mounted thereon to fixedly secure around a waist of the human.
• the strap assembly also dispenses the pressure resulting from the force described above.
• the elongated longitudinal curved-shaped back support defines a first predetermined displacement distance from the curvature area to a first vertical plane defined from the curvature area, and defines a second predetermined displacement distance from the curvature area to a second vertical plane defined from the curvature area.
• the first predetermined displacement distance is in a range of between 15 cm and 19 cm
• the second predetermined displacement distance is in a range of between 17 cm and 21 cm.
• the first predetermined displacement distance and the second predetermined displacement distance is in a range of between 17 cm and 19 cm.
• the base wall has a substantially rectangular shape and may include a semi-rigid material to serve as a structural base.
• the elongated longitudinal curved- shaped back support is made of a rigid material, such as plastic or PVC and covered with a soft padding-type material.
• the pad is made out of a soft material such as foam or a similar type material having foam-like characteristics.
• the ergonomic backpack may also comprise a micro massage system having massage units, an operating switch, and a battery source.
