Abstract
The utility model relates to a car safety technical field, specific saying is a low speed limit power protection mechanism, including spool, locking dish, spring, cutout, one side of spool and locking dish link to each other, and the below of spool one side is offered flutedly one, and the below of one side that locking dish and spool contacted is offered flutedly two, and recess no. 1 and recess are two corresponding, and recess no. 1 and recess are equipped with the cutout between two, and one side of cutout links to each other with the one end of spring, and the other end of spring and recess are one continuous, the utility model discloses a cubic shear structure, make things convenient for the spool of safety belt coiler in, neither disturb the normal roll -up effect of safety belt to can absorb the anteverted energy of passenger at low -speed collision, reduce the anteverted displacement of passenger, thereby optimized the protective properties to the passenger.
Description
Technical field
This utility model is related to technical field of vehicle safety, is concretely a kind of low speed limiter protection mechanism.
Background technology
In vehicle traveling process in low speed collision, the pre-tightening mechanism of seat belt typically will not start, now occupant can before
Incline, this makes the risk that occupant is contacted with car body increase.Need a kind of forcelimiting mechanism of low speed, occupant can be reduced and connect with car body
Tactile risk.The structure that there is presently no similar functions is applied in seat belt.In consideration of it, being necessary that invention one kind can be touched in low speed
The forcelimiting mechanism of energy absorption when hitting.
Content of the invention
This utility model breaches a difficult problem for prior art, devises a kind of low speed limiter protection mechanism, including spool, lock
Only disk, spring, cutout it is characterised in that：The side of spool is connected with lock plate, and the lower section of spool side opens up fluted
One, the lower section of the side that lock plate is contacted with spool opens up fluted two, and groove one is corresponding with groove two, groove one with recessed
It is provided with cutout, the side of cutout is connected with one end of spring, and the other end of spring is connected with groove one between groove two.
The top of described cutout is provided with jacking block.
This utility model compared with prior art, using block shear constitution, in the spool of convenient and safe Webbing retractor, no
Only do not disturb the normal volume adduction of seat belt, and can absorb, in low speed collision, the energy that occupant leans forward, before reducing occupant
The displacement inclined, thus optimize the protective value to occupant.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of cutout in this utility model.
Referring to Fig. 1 and Fig. 2,1 is spool, and 2 is lock plate, and 3 is groove one, and 4 is groove two, and 5 is cutout, and 6 is spring,
7 is jacking block.
Specific embodiment
In conjunction with accompanying drawing, this utility model is described further.
Referring to Fig. 1 and Fig. 2, this utility model devises a kind of low speed limiter protection mechanism, including spool, lock plate, bullet
Spring, cutout, the side of spool 1 is connected with lock plate 2, and the lower section of spool 1 side opens up fluted 1, lock plate 2 and spool
The lower section of 1 side contacting opens up fluted 24, and groove 1 is corresponding with groove 24, between groove 1 and groove 24
It is provided with cutout 5, the side of cutout 5 is connected with one end of spring 6, and the other end of spring 6 is connected with groove 1.
In this utility model, the top of cutout 5 is provided with jacking block 7.
In being embodied as, during low speed collision, cutout 5 energy absorption by way of cutting off, and in high speed pretightening machine
During structure effect, the jacking block above cutout 5 is cut off, and cutout 5 is all pushed back in lock plate 2 rapidly by spring 6, thus keeping away
Exempt from cutout 5 and interference is produced to pretension process.
This utility model, using block shear constitution, in the spool of convenient and safe Webbing retractor, does not only disturb seat belt
Normal volume adduction, and the energy that lean forward of occupant can be absorbed in low speed collision, reduce the displacement that occupant leans forward, thus excellent
Change the protective value to occupant.
