Abstract

The invention discloses an anti-whiplash safety belt for preventing an automobile seat back from turning backwards and causing whiplash to passengers. The anti-whiplash safety belt comprises a braid transversely blocked and pressed in the seat back and a winding device which is connected with one end of the braid, used for winding the braid and provided with a seat; the other end of the braid is connected with a side beam of an automobile frame through a connection device; and the winding device is connected with the side beam or middle vertical rod of the automobile frame. The braid is transversely blocked on the rear side of the automobile seat back, and the two ends of the braid are fixed on a rigid part of the automobile frame through the winding device and the connection device, wherein the winding device has a self-locking function, namely that when being pulled quickly, the braid is locked inside the winding device so that the braid cannot be pulled out. Therefore, in the case of rear-end collision of the automobile, the safety belt can block the seat back and prevent the seat back from turning backwards, and the passenger is hindered by the back and prevented from tilting backwards, thereby avoiding whiplash.

Description

technical field

[0001] The invention relates to a safety belt, in particular to a safety belt used for car seats to prevent whiplash. Background technique

[0002] When a vehicle is rear-end collided, it is easy to cause the neck of the occupant in the vehicle to stretch backward excessively, resulting in injury to the neck, which is called whiplash. The main factors affecting whiplash injury are head restraint posture and seat back turning stiffness. The backrest and seat board of the car seat are generally hinged. When the car is hit by a rear-end collision, the occupants on the seat and the backrest of the seat will turn backward under the action of inertia, thereby causing whiplash.

[0003] Three-point seat belts are commonly found in cars these days, and they have three mounting points, one on the B-pillar, one on the seat, and one on the rocker beam. This type of seat belt is mainly designed for frontal collisions, and will not work in rear-end collisions. In addit...
