Specific embodiment
The implementation and use of embodiment are discussed in detail with reference to the accompanying drawing.It will be appreciated, however, that the specific implementation discussed
Example is merely illustrative implementation and uses ad hoc fashion of the invention, the range being not intended to limit the present invention.It is each in description
The statement in the locations of structures of a component such as directions such as upper and lower, top, bottom is not absolute, opposite.When each portion
When part is arranged as shown in the figure, the statement of these directions is appropriate, but in figure when the position change of all parts, these direction tables
State also corresponding change.
In conjunction with Fig. 3 to Fig. 5, D ring of seat belt of the invention includes the first noumenon 40, the second ontology 50 and is arranged in first
Driving assembly 60 between body 40 and the second ontology 50.In the preferred embodiment, the first noumenon 40 and the second ontology 50 difference
It is arranged to fanning strip, and the plate shape area of the second ontology 50 is less than the plate shape area of the first noumenon 40.
Referring specifically to Fig. 3, the first noumenon 40 includes the first fanning strip 41, which is provided with the first mounting hole 42 and for safety belt
The strip groove 43 that ribbon 10 passes through.Second ontology 50 includes the second fanning strip 51, as shown in Figure 4, it is set on the second fanning strip 51
There is the second mounting hole 52.Pivotal axis 30 can pass through the first mounting hole 42 and the second mounting hole 52, so that 50 quilt of the second ontology
It is fixed on vehicle body, and the first noumenon 40 can be rotated around pivotal axis 30.
Driving assembly 60 is preferably mounted on the second ontology 50, for driving the first noumenon 40 towards vehicle when colliding
Direction of travel rotation, to prevent belt-strap 10 from accumulating in the end of the strip groove 43 of the first noumenon 40.Such as Fig. 4 institute
Show, in the preferred embodiment, driving assembly 60 includes cam, and the cam includes the rotating part being sheathed on pivotal axis 30
61, and from the periphery of rotating part 61 it is tangentially extending go out pushing part 62.Driving assembly 60 further includes gas generator 63, and by gas
The piston rod 64 that body generator 63 drives, wherein gas generator 63 and vehicle central processor communication, thus urgent in vehicle
When braking, signal is sent by central processing unit to trigger gas generator, and then the promotion of cam is pushed via piston rod 64
Portion 62.
To push rotation by the pushing part 62 of driving assembly convenient for the first noumenon 40, as shown in Figure 3, preferably in first
First fanning strip 41 of body 40 towards vehicle traveling direction side is equipped with convex block 44.The convex block 44 can be with the first fanning strip 41 1
It is body formed, also can it is separately formed after be fixed to one another.
When colliding, Vehicle security system starting, central processing unit sends a signal to gas generator 63, with triggering
Gas generator detonation, driving piston rod 64 pushes the pushing part 62 of cam to rotate it around pivotal axis 30, as shown in FIG. 6.
Once pushing part 62 contacts the convex block 44 of the first noumenon 40, the further promotion of piston rod 64 will promote convex block 44 along pushing part 62
Surface it is mobile so that the first fanning strip 41 is rotated towards vehicle traveling direction in the direction of the arrow.Advantageously, in preferred implementation side
In formula, after gas generator is entirely pneumatic, the first noumenon 40 can be driven to rotate 45 degree, such as Fig. 7 relative to the second ontology 50
Shown in, to reach good anti-accumulation effect, however other angular ranges are also feasible.
It should be understood that in alternate embodiments, piston rod 64 can also push directly on the convex block 44 of the first noumenon 40 and
Without via cam, as long as convex block is arranged to have enough length.In addition, the shape of the first noumenon and the second ontology also may be used
It changes according to actual needs, however it is not limited to above-mentioned sector structure.
Technology contents and technical characterstic of the invention are had revealed that above, it being understood, however, that in creative ideas of the invention
Under, those skilled in the art can make various changes and improve to design disclosed above, but belong to protection of the invention
Range.The description of above embodiment is exemplary rather than restrictive, and protection scope of the present invention is by claim institute
It determines.
