The utility model relates to a car blet is locking ware with higher speed in twinkling of an eye to install on the safety belt of car with the clip mode, this car blet is locking ware 10 with higher speed in twinkling of an eye includes a safety belt book turning head 20 and a fixation clamp 30, and this safety belt book turning head 20 becomes with rotatable mode and this fixation clamp 30 and links. The safety belt turning head 20 includes a turning head body 21, and a pair of baffles 22 bent backward from two ends of the turning head body 21 by a predetermined length and arranged parallel to the turning head body 21, and an accommodating space 23 is formed between the turning head body 21 and the pair of baffles 22. The main body 21 further includes a pair of separately disposed coupling blocks 24 disposed at the bottom of the main body 21.

The retaining clip 30 includes a front clip 31, a rear clip 40 and a seat belt fastener 44. The common connection end of the front and the

back clamping pieces

31 and 40 is a pivot end; and the other side common connecting end is connected in a buckling mode to form a buckling end which can be in an opening or closing state. The front clip 31 has a protrusion 32 formed at the top thereof, which is inserted between the two coupling blocks 24 of the seat belt folding head 20, and a support shaft 33 is inserted into the coupling blocks 24 and the protrusion 32, so that the seat belt folding head 20 is coupled to the fixing clip 30, and the seat belt folding head 20 can rotate backward. The front clip 31 has a first end (a fastening end), a second end (a pivot end), and a fastening element 34 extending backward from the first end of the front clip 31, and a locking groove 35 is formed on the inner surface of the fastening element 34. The front jaw 31 further includes a hook 36 formed at a front portion of the front jaw 31.

The rear clip 40 has a first end (fastening end) 41 and a second end (pivoting end) 42; when the rear clip 40 approaches the front clip 31, the first end 41 of the rear clip 40 slides into the slot 35 of the front clip 31. Furthermore, the first end 41 has a protrusion 43 with a slope, so that the first end 41 of the rear clip 40 can easily slide into/out of the slot 35 of the front clip 31.

The belt fastener 44 is an L-shaped member rotatably coupled to the rear clip 40; applying a downward force to the belt lock 44 pivots the belt lock 44 about the pivot axis to move the belt lock 44 from the unlocked position shown in fig. 6 to the locked position shown in fig. 7.

The instant acceleration lock 10 further includes a pivot structure 50 having a protrusion 51 disposed at the second end of the front clip 31; and a bifurcating arm 52 disposed at the second end 42 of the rear clamping piece 40; the protrusion 51 is inserted into the fork arm 52, and a fulcrum 53 is inserted into the protrusion 51 and the fork arm 52, so that the rear clamping piece 40 rotates around the fulcrum 53, and the rear clamping piece 40 moves from the open position shown in fig. 5 to the closed position shown in fig. 3.

Fig. 8, 9 and 10 show the usage of the instant acceleration lock 10 for a car seat belt according to the present invention mounted on the car seat belt 60, and the instant acceleration lock 10 for a car seat belt is applicable to any seat belt 60 of any vehicle. Firstly, the rear clip 40 of the car seat belt instantaneous acceleration lock 10 is opened to an open state, then the seat belt 60 is fastened and pulled out to a usage length allowing a small movement of a body, and then the seat belt 60 is placed in the accommodating space 23 between the bending head body 21 of the seat belt bending head 20 and the baffle 22, and a pressure is applied on the rear clip 40 to force the first end 41 of the rear clip 40 to rapidly slide into the clamping groove 35 of the front clip 31 through the inclined plane bulge 43, at this time, the car seat belt instantaneous acceleration lock 10 is clamped on the seat belt 60 (as shown in fig. 8); finally, the seat belt fastener 44 is pulled downward to make the seat belt fastener 44 abut against the seat belt 60, so that the car seat belt instantaneous acceleration lock 10 is stably fixed on the seat belt 60, as shown in fig. 9 and 10.

Fig. 11 and 12 show the instant acceleration lock for the safety belt of the present invention installed on the safety belt; when the pulling force applied to the seat belt 60 is released, the seat belt 60 automatically winds up to move the instantaneous acceleration lock 10 upward along with the seat belt 60 until the seat belt turning head 20 abuts against the seat belt eye 61, the upper edge of the turning head body 21 of the seat belt turning head 20 becomes a fulcrum, and the seat belt 60 continues to be pulled, so that the seat belt turning head 20 rotates downward by ninety degrees, the seat belt 60 located in the instantaneous acceleration lock 10 is bent by about ninety degrees, and the seat belt 60 enters an instantaneous acceleration ready state.

When the automobile collides or is emergently braked in the running process, the body rushes forward, the bent safety belt 60 is suddenly and rapidly straightened, the tail end of the safety belt 60 immediately generates strong instant acceleration, and the automatic locking device of the safety belt 60 is forcefully started to lock the safety belt 60; when the locking function is exerted, the safety belt 60 automatically restores the state of being lightly attached to the body; if the body naturally leans forward, the safety belt 60 is not locked and does not affect the free movement of the body.

To unlock the seat belt 60, the seat belt locking member 44 is pulled upward (see fig. 10) to allow the momentary accelerator lock 10 to be in a free state (see fig. 8) and slide on the seat belt 60.

Referring to fig. 13, when the user gets off the vehicle, the user can hang the seat belt buckle 62 on the hook 36 of the front clip 31 to keep the seat belt 60 in order.

The instant acceleration locking device of the utility model can fix the safety belt to be pulled out for a certain length, so that the safety belt has a certain space away from the chest, and the safety belt is prevented from tightening the body, thereby obtaining the comfort level when the safety belt is fastened; on the other hand, the safety belt can be bent by about ninety degrees by the function of the safety belt turning head of the instant acceleration locking device, and when the safety belt is pulled by strong instant acceleration, the automatic safety belt locking device can be started more sensitively and rapidly to lock the safety belt no matter the speed of the vehicle is high or low.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
