Embodiment Construction
[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0038] see Figure 3 to Figure 7 , what is shown in the figure is a pretensioned safety belt with elastic deformation as the pretensioning power, including a safety belt body (not shown in the figure), a retractor (not shown in the figure), a rack guide groove 300, rack 400, electromagnetic valve 500 and shrapnel 600.
[0039] retractor (see figure 1 and figure 2 ) consists of a hollow shaft and retractor gears fixedly arranged at both ends of the hollow shaft. The fixed shaft is passed through the hollow shaft of the retractor, and the retractor is fixedly installed on the casing of the pretensioner. seat belt body (see figure 1 and figure 2 ) is fixed on the hollow shaft. The rack guide groove 300 is arranged on one side of the retrac...

The invention discloses a warning type safety belt using elastic deformation as warning power, comprising a safety belt body, a reel, a rack guide channel, a rack, an electromagnetic valve and a spring. One end of the rack in contact with a rack fixing plate is provided with a calibration traction port, the other end of the rack is mounted in the rack guide channel through a locking and adjusting part, the calibration traction port of the spring is connected with a calibration device in the case of calibration required, deformation of the spring is adjusted through the locking and adjusting part according to parameters displayed by the calibration device so that warning power of the spring is kept uniform. The warning type safety belt has the advantages that the requirements on the uniformity of an elastic material and a mounting process are effectively reduced, the elastic material is reusable, the warning performance is kept uniform with the parameters, and the applicable range is greatly widened.
Description
technical field [0001] The invention relates to the technical field of automobile safety belts, in particular to a pretensioned safety belt with elastic deformation as the pretensioning power. Background technique [0002] The pre-tensioned seat belt is to strengthen the restraint of the occupant and lock the seat belt in the case of a car collision or emergency stop and other drastic changes in speed, so as to prevent the body from leaning forward and colliding with the steering wheel, instrument panel and glass windows. device. In the pretensioned safety belt using elastic deformation as the pretensioning power, the elastic deformation and the stroke during the deformation recovery process are particularly critical. [0003] see figure 1 and figure 2 , shown in the figure is an existing pre-tensioned seat belt that uses shrapnel to generate pre-tightened power, including a seat belt body 10, a retractor 20, a rack guide groove 30, a rack 40, a fixed shaft 50, Electrom...
