Rigid automatic control type waist control protective gear

The invention relates to a rigid automatic control type waist prevention and protection device, in particular to a bending rigidity strength which can automatically adjust the waist prevention protection device according to different bending angles of the wearer, so as to limit the wearer's bending action and avoid the occurrence of the lower back. The prevention and treatment of pain.

Lower back pain is caused by muscle or ligament strain, disc damage or a combination of the above reasons. The literature indicates that long-term bad working posture can also cause lower back pain; currently, the more common equipment for slowing down lower back pain is bundle The waistband can be sleeved on the circumference of the waist to form a protection, and can provide a partial support effect, thereby achieving the effect of reducing the load on the waist, but the above-mentioned simple belt structure can produce protection and auxiliary support effects. Limited, most of them can only be used for patients with mild lower back pain or non-working aids. For the more serious patients with back pain or the accessories needed for work, the above traditional belt products are Unable to achieve effective protection.

To this end, there are various work aids (ie, waist protectors) commonly used in the prevention and treatment of lower back pain, for example, a plurality of upright accommodating portions are provided in the above-mentioned belt for accommodating elastic support. The support strip can be used to form an elastic protection support for the waist when bending, and the wearer can replace the support rods with different hardness and elasticity according to different needs to increase the overall application range; however, the protection design It is not possible to automatically adjust the bending stiffness according to the different bending angles of the wearer and provide appropriate warning effects.

U.S. Patent No. 7,744,552 B1 discloses a "PERSONAL UPPER BODY SUPPORT DEVICE FOR LOWER BACK MUSCLES ASSIST", which mainly includes: a main body (main-body 10) and a leg engagement member 20 (30). a body assembly (saddle means assembly 40), a vertical upper member 50, and a belt assembly 60, wherein the belt assembly is tied to the waist of the wearer and the The seat assembly is fixed to a portion of the front abdomen of the belt assembly, and the body is pivotally mounted on the base assembly. The upper upright member is disposed in the middle portion of the body and extends upwardly at a top end of the upper upright member. A soft roller 51 is disposed to abut against the chest position of the wearer, and a shaft having a relative torsion elasticity (shaft 110, 112) is respectively protruded outwardly from both sides of the seat assembly at both ends of the body. And the two leg engaging members are respectively coupled to the two shafts at one end thereof, and the other end portion of the two leg connecting members is provided with a contact plate 25 which can be in contact with the wearer's lower limbs. If the wearer performs the forward bending action, the front chest will push the upper upright member to pivot through the soft roller, and the upper vertical member disperses the force through the body, the two-axis, the two-legged connecting piece and the contact plate. To the legs, and using the pivotal elasticity between the two shafts and the body to form a buffer and support, thereby reducing the load on the waist and reducing the damage; however, the mechanism is worn during work, although it can directly provide the lower back Supporting force, while avoiding excessive execution of wrong posture and movement during work, to reduce the incidence of lower back pain, but in practical applications, because it is placed in the chest and abdomen position of the wearer, it will seriously affect the action when worn. Freedom, the general wearer's acceptance is quite low, at the same time, fixing the lumbar position for a long time, it is easy to cause the abdominal muscles and back muscles to shrink without normal force.

Another working aid is provided with a plurality of pivoting connecting rods on the wearer's back ridge, and a pneumatic cylinder with driving support between the connecting rods, and receiving a sensing element to detect the lower back muscle action by using a management circuit Sensing signals, and driving the pneumatic cylinders respectively through a DC motor to change the angle of the rod driven by the pneumatic cylinder, thereby generating the supporting force required for the lumbar force application; however, the structure can be Achieve the purpose and effect of auxiliary protection, but the body of the body is too large, and needs to be placed on the seat relative to the spine, which will cause excessive load on the lower back muscles of the wearer; at the same time, although it has a multi-degree of freedom design, the mechanism There is no protection or limitation for the poor working posture, and there are still some shortcomings in practical application.
