Problems solved by technology

[0010] 2. The structure of the seat belt with the above structure is complex, and due to the use of gunpowder or explosives as the power source, the reliability of the above device will decrease over time
Moreover, it is more difficult to manufacture such a device
[0011] 3. Since the above devices require sensors and a central controller, the product is expensive
[0012] 4. When the above-mentioned seat belts are used on mobile devices, such as vehicles, the cost of adaptation tests is high and the cycle is long

Abstract

A prestretching and energy sucking device for seat belt has said seat belt and two prestretching mechanisms. At elast one contact-type trigger is arranged on the seat frame, and connected to a controller via pull string. When the controller is at the first position, a pin can be inserted in the hole of movable element and the locked seat belt is at normal fixed position. When the controller is at the second position, the pin can be drawn out of the hole and the seat belt is stretched by prestretching mechanism.

Description

technical field [0001] The invention relates to a pretensioning and energy-absorbing device for a safety belt, in particular to a pretensioning and energy-absorbing device for a safety belt on a driver's or a passenger's seat. Background technique [0002] In the prior art, the safety belt used by the general vehicle driver or passenger is composed of a retractor, a webbing and a buckle. Among them, the two-point fixed type only limits the occupant's waist, which is called a waist belt; the two-point fixed type only limits the upper body of the occupant. are called shoulder straps. The three-point fixed seat belt restricts the occupant's waist and upper body at the same time. This three-point fixed seat belt is usually called a waist-shoulder joint seat belt. [0003] Existing safety belts mainly rely on the tensile deformation of the webbing to absorb energy, thereby reducing the intensity of the collision, wherein the tensile deformation of the shoulder straps can reach 4...
