SUPPORT JACKET Bb+FIT SLIM
Among the “SUPPORT JACKET Bb+” series, which guides the wearer into a posture that is less stressful on the waist and body when lifting and lowering loads, standing, or working in a mid-back or forward leaning position, the “SUPPORT JACKET Bb+FIT SLIM” is a model designed for workability and comfort. Regardless of the type of work, it fits just right and reduces fatigue.

Structure
System that assists the lower back and the body
The cause of lower back problem are said to be frequent lifting movements and a slouching posture. The jacket gently reduced the strain on the lower back, guiding the wearers who tend to have bad posture at work towards an ideal aposture by helping abdominal and back muscles to function normally.
Bb+ (Backbone Plus) concept
The second backbone Bb+ (Backbone Plus) was developed to create another trunk, from the backbone to the pelvis. This Second Backbone has the same arch and moderate mobility as a human backbone, controlling increased pressure on intraspinal disks and maintaining a posture angle that puts less strain on the body.
Functions and Features
Form navigation function
By attaching the second backbone Bb+ (Backbone Plus) to the back of the jacket, it guides the spine and hips into an ideal posture.
It also reduces the great strain on the back and hips by reducing the stooping posture associated with work.
Lumbar support function
A large waist belt to stabilize and protect the lower back wraps around the spine, abdominal muscles, and back muscles. This maintains abdominal pressure and reduces strain on the hips and spine during work.
Muscle function
Based on ergonomics, the Muscle Belt is attached from the knee to the waist for leg muscle assistance. This assists the user’s ability to bend forward and get up during work, thereby reducing the burden on muscles.
Bone detachment function
The backbone can be removed and the cloth (fabric) part can be washed in a laundry net.
The main body can be easily attached after washing.
Hip belt fitting system
The tightening adjustment of the waist belt can be easily made with a dial.
Effect
Effective in all working postures
Effective for work in all postures: upright, leaning forward, stooping, mid-back, and crouching.
Effectiveness verification by myoelectricity
Wearing SUPPORT JACKET Bb+FIT SLIM reduces muscle strain by up to 43% *
*Measuring area: erector spinae muscle, rectus femoris muscle
*Methodolgy: Adult male in his 20s. Measured 10 movements of raising and lowering a 10 kg load between the floor and a table.
*Based on in-house testing
Measured pressure on lumbar disks
Measurement of pressure when raising and lowering a 10 kg load from the floor to a table at a height of 70cm
■Comparison of body forward lean angle
・Without SUPPORT JACKET Bb+FIT SLIM : 67.7°
・With SUPPORT JACKET Bb+FIT SLIM : 59.7°
■The body forward lean angle improved significantly when wearing SUPPORT JACKET Bb+FIT SLIM.
The 8.0° decrease in body forward lean angle results in 6.5kg decrease in immediate load pressure.
■The pressure reduction effect on the lumbar intervertebral discs when the same task is repeated 100 times over 5 days
6,500kg (a decrease of 6.5 tons)
*Calculation results based on a model with a height of 163 cm and weight of 55 kg.
*Methodology: 15 healthy adults (male and female) aged 20s engaged in lifting and unloading a 10 kg load 30 times in 10 minutes, both with and without wearing the product, following a metronome. The entire process was recorded on video. Analysis of the angles of the neck, body, knees, etc., was conducted on the final trial images. Evaluation was performed in September 2018 using REBA (ISO/TR12296), an internationally recognized risk assessment method for occupational back pain.
*Based on a survey by Dr. Mitsugu Yoneda, Associate Professor of Rehabilitation Science, Department of Health Science, Kanazawa University, Kanazawa University, Japan.
Result of test on “effect of inducing good working posture” based on the SUPPORT JACKET Bb+ concept
The “SUPPORT JACKET Bb+” function to restrict a forward tilting angle of the body trunk, which helps workers to maintain good posture. The corset function and elastic fabric covering from the knees to the lower back provide significant assistance for body movements. Lower back pain prevention is a serious health issue being tackled as a national policy. This product is expected to exhibit a positive effect in diverse fields where lower back pain prevention measures are urgently required.
