Embodiment Construction

[0012] refer to figure 1 , a car safety belt that can be electrically fine-tuned and tightness disclosed by the present invention mainly includes a webbing and a winder 1 . The winder 1 includes a frame 2 and a reel arranged on the frame 2 , one end of the webbing is wound on the reel, and a rotating shaft 3 of the reel is fixed on the frame 2 . One end of the rotating shaft 3 is fixedly mounted with a first gear 4 at a position outside the frame 2 . The rotation of the reel can be controlled by controlling the rotation of the first gear 4 .

[0013] The present invention utilizes the second gear 5 , the motor 6 and the controller 7 to control the rotation of the first gear 4 . Specifically, the second gear 5 is fixed on the drive shaft of the motor 6 , the second gear 5 meshes with the first gear 4 , and the controller 7 controls the motor 6 to work. The controller 7 may be provided at an in-vehicle location that is easily accessible by passengers. In order to make the ad...

Abstract

The invention discloses an automobile safety belt which can be electrically and finely adjusted in tightness degree. The automobile safety belt comprises a braided belt and a winder, wherein the winder comprises a rack and a winding drum arranged on the rack. One end of the braided belt is wound on the winding drum, a rotary shaft of the winding drum is fixed to the rack, and one end of the rotary shaft is fixedly provided with a first gear at the position on the outer side of the rack. The automobile safety belt further comprises a second gear, a motor and a controller, wherein the second gear is fixed to a driving shaft of the motor and is meshed with the first gear, the controller controls the work of the motor, and the diameter of the second gear is smaller than that of the first gear. The rotation of the winding drum of the winder can be actively controlled in the mode that the motor is matched with the gear, the braided belt can stretch out or retract back by adopting different rotating directions, and accordingly the stretching length of the braided belt is finely adjusted. By utilizing the automobile safety belt, a passenger can adjust the tightness degree of the braided belt in an electric mode after wearing the safety belt, and the automobile safety belt is convenient to use and ensures comfort and safety in wearing.

Description

technical field [0001] The invention relates to an automobile seat belt, in particular to an electric fine-tuned automobile seat belt. Background technique [0002] The current automobile safety belt utilizes a winder to wind up the webbing. When in use, people pull out the webbing by hand, and after pulling it to a certain length, it can be locked by the dead bolt. This hand-drawn structure is difficult to ensure that the elongated length of the webbing completely matches the structure of the human body. If the webbing is stretched out too short, the webbing will tighten the human body, and if the webbing is stretched out too long, the protective effect of the seat belt will be reduced. Therefore, it is currently necessary to provide a structure that can fine-tune the telescopic length of the webbing, making it more convenient and comfortable for people to wear the seat belt. Contents of the invention [0003] In order to achieve the above purpose, the present invention ...
