According to effect and the operation principle of car belt, safety belt can limit the unexpected movement of occupant, a kind of tighting device for support that during to prevent or to alleviate brake hard in traffic accident, occupant is hurt.When its protection philosophy is collision accident generation, safety belt is pulled fast; the lock of the inside rod can take out of due to the quick rotation of safety belt roller by the power that is centrifuged; rapidly that safety belt is locked, safety belt freely can not be extracted out from coiler, thus reach the object ensureing driver and crew's safety.Safety belt principle is applied in backpack strap design the function realizing shoulder belt buffering antihunt action and correct knapsack person faulty posture by the present invention.
Summary of the invention
The object of the invention is for existing knapsack antidetonation and prevent the habitual body of children lean forward in deficiency, utilize the effect of backpack strap on fixing knapsack and body relative position, a kind of new type of safe belt backpack shoulder belt is proposed, to reach the function of buffering antihunt action and rectification knapsack person faulty posture.
For solving above technical problem, the present invention is achieved through the following technical solutions: a kind of new type of safe belt backpack shoulder belt design, the design of this shoulder belt is made up of common shoulder belt, the special ribbon of car belt material, shoulder belt length control device three part.
Described backpack shoulder belt design feature is: shoulder belt is synthesized by the shoulder belt of two kinds of materials, and upper part shoulder position is common material shoulder belt, and lower part is car belt material special elastic ribbon near waist.This elastic woven tape intensity is high, has certain extensibility, good energy absorption, good wearability, against weather (cold, heat, water, light, corrosion) and color fastness.In addition, flat appearance is soft comfortable.Be fixedly connected with by upper and lower bi-material shoulder belt, junction is non-telescoping, arranges webbing length control device in the special ribbon bottom of car belt material and inclusion junction, for controlling the folding and unfolding degree of shoulder belt.
By such scheme, when applying of the present invention, in normal state, shoulder belt can be close to inclusion back to knapsack, when human body knapsack, and slowly pull-out ribbon; Human body carries bag when standing still, and the special ribbon of car belt material can tighten up according to the bodily form under the effect of ribbon control device; Human body walking or race drive knapsack vertical tremor when jumping, shoulder belt under tension can be elongated, cause knapsack up-down vibration that shoulder belt can be made to apply larger pressure at shoulder, control device meeting backrush part ribbon now bottom shoulder belt also pins rotating axle, shoulder belt length is made to maintain OK range, the vibrations of tightening up reducing knapsack of shoulder belt; When human body leans forward because of the habitual body that bears a heavy burden, shoulder belt can be elongated, and this timed unit is also by automatic rewinding ribbon, and ribbon shortens, meeting straight and upright body consciously after human body sensory shoulder belt tightens up, thus reaches the effect of opposing faulty posture.
