Power of exoskeleton
The "Second Spine Bb+ (Backbone Plus)"
The independently developed S-shaped structure creates a reaction force effect,
it reduces the burden on the lower back in working postures.
"In the case of a forward leaning posture"
The lower part of the Bb+ creates a reaction force effect when leaning forward, it supports your lower back and assists in the forward leaning posture.
"In the case of backward leaning postures"
The lower part of the Bb+ produces a reaction force effect on the upper body's bending back, it supports the backward leaning posture while preventing lordosis

It is estimated that back pain accounts for about 60% of all illnesses and injuries occurring in the
workplace.
SUPPORT JACKET️ has been developed as workwear with a revolutionary function
to reduce the strain on the lower back and body by means of an exoskeleton "second spine"
originally developed for various work situations such as "logistics, manufacturing, construction,
agriculture, forestry, fishing, service industry, nursing and medical care".
Workers' compensation measures
Reduced risk of back pain
Improving the work environment
We conducted joint research with Kanazawa University based on the needs and opinions of more than thousands of companies.
From the wearer's perspective,
we focused on a posture that reduces strain on the lower back and body when lifting and unloading luggage, standing, or working in a half-backed or forward-leaning posture.
We have developed an assist suit equipped with three innovative functions.
The cause of lower back problems is said to be frequent lifting movements and forward bending movements. It guides the bad posture that is often performed during daily work into the ideal posture, allows muscles such as the abdominal muscles and back muscles to function normally, and is gentle on the body and reduces the burden on the lower back.
We have independently developed the "second spine (Bb+)" from the spine to the pelvis to create another core. The arch, which is the same as the human spine, and moderate mobility suppress the increase in pressure on the intervertebral discs and maintain a posture angle that is less stressful, creating the ideal form for working postures.
[Measured pressure on when raising a 10kg load from the floor to the desk]
＊Assuming that the wearer is 172cm tall and weighs 64kg.
＊Verification method: We made 10 healthy adult males raise and lower 10kg weight tested for 30 times in 10 minutes according to a metronome.
Participants did the same for both cases of wearing the jacket and not, which were recorded in a video. We then analyzed the angles of the neck, trunk, and knees of the participants from the video and assessed the data with the REBA method recommended in ISO/TR12296, international standards for evaluating occupational lower back pain.
| With or without the SUPPORT JACKET Bb+ | Without | With SUPPORT JACKET Bb+ |
|---|---|---|
| Forward tilt angle for lifting motion from the floor | 66.6° | 49.1° |
| Improved trunk forward tilting angle when wearing the SUPPORT JACKET Bb+ | Reduced by 17.5° ＜Momentary load pressure reduced by 22.4kg＞ |
|---|
| Pressure reduction effect on lumbar disks when repeating the same movement 100 times for five days. | Reduction of 11,228kg（approx.11.0t） ＜Further effect can be obtained for more frequent movement＞ |
|---|
"SUPPORT JACKET Bb+" has the effect of suppressing the forward leaning angle of the trunk, and has been
confirmed to be effective in promoting good posture during work. In addition, the corset function and
elastic fabric from the knees to the waist are thought to create a great sense of assistance. This product is
expected to be effective in a number of different areas where back pain prevention is needed.

Use of a support jacket reduces the burden on the lower back by up to 43％※
※As an adult male in his 20s had a muscle potential sensor attached to his back surface, he lifted a 10 kg load from the floor to a table and placed it on the floor (repeated 10 times), and the muscle contraction state of his spinal erector muscles was measured with an electromyograph.
It was confirmed that wearing the device reduced the burden on the lower back by a maximum of approximately 43％. (own research).
