In the above-mentioned conventional backpack bag, the bag body is made of a hard material in order to protect the items to be stored.

By the way, since the user's back is not flat, the contact portion between the back and the bag body carried on the back is partial.

Therefore, not only the weight of the backpack bag is concentrated on the narrow part of the user's back, but also an irregular gap is formed between the backpack bag and the user's back.

When such a phenomenon occurs, in the former case, it is assumed that pain is likely to occur in the part of the back where the backpack bag is in contact, and in the latter case, the contact between the backpack bag and the user's back is assumed. Since the area is small, it is not possible to prevent the backpack from shifting in the left-right direction of the user's back, and it is assumed that there is a problem that a sense of stability cannot be obtained.

The present invention is intended to solve the above-mentioned conventional problems by attaching a back support having a shape matching the contour of the user's back to the contact portion of the back carrying bag with the user's back. In particular, it is a problem to be solved to provide a manufacturing method capable of easily manufacturing this back support, and to provide a backpack that disperses the backpack load and has less lateral displacement.

In the method of manufacturing the back support for a backpack bag of the present invention, the portion of the backpack bag that is attached to the backpack used to be carried and is brought into contact with the user's back is adapted to the contour of the user's back. A method for manufacturing a back support, which is a measurement step of three-dimensionally measuring the contour of the user's back and quantifying the contour of the user's back as three-dimensional data, and a preset planar shape. It consists of a three-dimensional data conversion process in which the two-dimensional data of the reference back support of the above is converted into three dimensions based on the digitized three-dimensional data, and a production process of producing a three-dimensional back support based on the three-dimensional data. It is characterized by that.

According to the method of manufacturing the back support for a backpack, the contour of the back of the user is measured three-dimensionally and quantified as three-dimensional data in the measuring step.

Then, in the three-dimensional data conversion process, to the preset two-dimensional data of the reference back support, the data of the dimension orthogonal to the two-dimensional data is added based on the digitized three-dimensional data. Make it three-dimensional.
As a result, numerical information on the three-dimensional shape of the back support can be obtained.

Then, by producing the back support based on the numerical information of the three-dimensional shape, the three-dimensional back support can be obtained.

In this way, the contour of the back of the user can be directly measured, and the back support can be three-dimensionally produced based on the measurement result. Therefore, the contour of the back support can be made very close to the back of the user. can.

The contour measurement of the user's back is preferably performed using a 3D scanner.
As a result, in the above-mentioned contour measurement, the measurement can be performed non-contactly, and the burden on the user at the time of contour measurement can be reduced.

When measuring the contour of the user's back, preferably, a reference point is set at a specific position on the back, and the three-dimensional data is obtained by displacement from the reference point.

This makes it possible to prevent the deviation between the obtained three-dimensional data and the contour of the user's back.

The reference point can be easily set by attaching a marker to the back of the user.

The reference point is preferably set at the site of the second lumbar vertebra or the third lumbar vertebra of the user's spine.
This is because the user's back is the lowest in the second lumbar vertebra or the third lumbar vertebra, and the contour of the user's back can have a high height difference.

A 3D printer can be used to produce the back support.
By using this 3D printer, it becomes possible to produce using the numerical information converted into the three-dimensional data, and the production becomes easy.

When measuring the contour of the back of the user three-dimensionally, it is preferable that the user is equipped with a bodice that makes the contour of the back of the user stand out by tightening the upper body of the user.

This makes it possible to sharpen the contour of the user's back, improve the dimensional accuracy of the back support to be produced, and improve the familiarity with the user's back.

The backpack can be obtained by attaching the back support for the backpack thus produced to the portion of the backpack that faces the back of the user.

When the user carries the bag on his back, the back support is brought into contact with the user's back.
Here, since the back support is formed along the contour of the user's back, these contacts are close to surface contacts.

As a result, the load of the backpack bag is widely dispersed and supported on the back of the user, the concentration of the load on a specific portion is prevented, and it is possible to prevent the user from being injured.

Further, at the contact portion between the back support and the user's back, a hook is formed in the left-right direction and the up-down direction of the back.

As a result, the back-carrying bag is suppressed from being displaced from the user's back, and the usability is improved.

It is preferable that the back support is attached to the back-carrying bag by, for example, providing a storage portion in a portion of the back-carrying bag facing the back of the user and storing the storage portion in the storage portion.

However, in this case, it is necessary to use a flexible material for the portion of the backpack that faces the back of the user.

As a result, the backpack can be deformed and fitted to the user's back.
Further, by interposing a flexible material between the back support and the back, this flexible material can be used as a cushioning material for the back.

According to the present invention, when a user carries a back-carrying bag on his / her back, it is possible to easily produce a back support in which the contact of the back-carrying bag with the user's back is as surface contact as possible.
