Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a cushioning member for backpacks.
In particular, the present invention relates to a cushioning member for backpacks used in backpacks such as school bags.

(Prior Art) FIG. 13 is a sectional view showing an example of a conventional school bag. This school bag 1 is designed to make it easy to put teaching materials etc. into it, and to prevent the teaching materials inside from being dented or damaged even if it is pressed down carelessly. It is made of a relatively hard material and is designed to retain its shape well.

In the case of the school bag 1 made of such a relatively hard material, it hits the back and other body parts of the person carrying it relatively firmly, so
A cushioning surface material 5 is formed on the back plate 2 below the attachment 4 of the shoulder strap 3.

(Problem that the invention aims to solve) In such a conventional school bag, if the person carrying it on their back is suddenly pushed from behind, the person's head may fall near the top of the back plate or lid. There is a risk that it will fall over and cause a mild whiplash phenomenon due to the impactful shaking. Furthermore, in that case,
There is a risk that the back of the head or neck of the person carrying the bag may hit the relatively hard backboard or the upper part of the lid, causing injury.

Additionally, if a physically weak child is carrying a relatively heavy backpack such as a school bag, the center of gravity will be on the school bag, and even the slightest impact will cause the child to fall over at an extremely high rate. There is a high possibility of whiplash and injuries like those described above.

Therefore, the main purpose of this invention is to make it possible to make the tilt angle of the head of the person carrying a backpack more gentle even if a sudden shock is applied from behind, for example, and to make it possible to make the angle at which the head of the person carrying a backpack leans more gently. Never give up. An object of the present invention is to provide a cushioning member for a backpack.

(Means for Solving the Problems) This invention provides a buffer section and a detachable structure that protrudes from the outer surface of at least the upper part of the back plate of the backpack or the upper part of the lid piece adjacent to the back plate. This is a cushioning member for a backpack, including attachment means for freely attaching it.

(Function) The buffer section is detachably attached to at least the upper part of the back plate of the backpack or the upper part of the lid piece adjacent to the back plate by the attaching means. The cushioning section attached to the backpack gently supports the back of the head of the person carrying the backpack.

(Effects of the invention) According to this invention, the back of the head of a person carrying a backpack is supported, so that the head will not be bent backwards to an unreasonable angle due to an unexpected shock, or the head will be shaken in a shocking manner. This prevents the so-called whiplash phenomenon from occurring.
Moreover, in this case, the shock to the back of the head is softened by the shock absorber, so there is no chance of injury to the back of the head or the back of the neck.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is a perspective view showing an embodiment of this invention. This buffer member 10 includes a substantially rectangular parallelepiped-shaped buffer section 12, for example, having a length of 16 cm, a width of 5 cm, and a height of 4 cm. This buffer section 12 is formed by covering a relatively elastic buffer material 14 such as porous synthetic resin such as polyurethane foam or sponge rubber with a surface material 16 such as cloth or leather material. .
