Description.
Inertial mass 5 is rotatably arranged on rotating wheel 4, and inertial mass 5 is located at the proximity sensor gear 3 of rotating wheel 4
Side (for example, left side in Fig. 1).Reference picture 1 simultaneously combines Fig. 2 and Fig. 3, the side table of the proximity sensor gear 3 of rotating wheel 4
Face is provided with the first locating part 91 and the second locating part 92 being spaced apart from each other, and inertial mass 5 is in the first locating part 91 and the second limit
It is rotatable between the part 92 of position.
As shown in Figures 2 and 3, generally " C " shape of inertial mass 5, the center of rotation of inertial mass 5 and the center of rotating wheel 4 are not
Coaxially, the first locating part 91 and the second locating part 92 are respectively adjacent to the both ends setting of inertial mass 5 and are respectively positioned on the outside of inertial mass 5
(i.e. the side away from the center of rotating wheel 4), so as to which inertial mass 5 can be swung in a less scope, the first locating part 91
It is respectively two extreme positions that inertial mass 5 is swung with the second locating part 92.It is appreciated that the first locating part 91, second is spacing
Concrete shape and the arrangement on rotating wheel 4 of part 92 and inertial mass 5 etc. can according to actual requirement specific design,
The present invention is not especially limited to this.
Further, compression spring 7 is additionally provided with rotating wheel 4, compression spring 7 is used to inertial mass 5 being compacted to and first
Locating part 91 often coordinates.When safety belt 101 be drawn out and the acceleration that is drawn out within the specific limits when, i.e., inertial mass 5 is not gram
The elastic force of compression spring 7 is taken, the relative rotation wheel 4 of inertial mass 5 is static, now inertial mass 5 and the synchronous rotary of rotating wheel 4.
When the acceleration that safety belt 101 pulls out exceeds above range, inertial mass 5 overcomes the elastic force of compression spring 7, inertia
Block 5 and rotating wheel 4 relatively rotate, specifically, one end (for example, right-hand member in Fig. 2 and Fig. 3) and first of inertial mass 5
Locating part 91, which departs from, to be coordinated, and the other end (for example, right-hand member in Fig. 2 and Fig. 3) of inertial mass 5 is towards close to the second locating part 92
Direction motion.
When the above-mentioned other end of inertial mass 5 moves to a certain position, the above-mentioned other end and sensor gear of inertial mass 5
3 coordinate, such as the cooperating teeth 51 on the above-mentioned other end of inertial mass 5 engages with the internal tooth in sensor gear 3.Such as in this hair
In bright one of example, a side surface of the neighbouring rotating wheel 4 of sensor gear 3 has holding tank, the inner circumferential of holding tank
There is internal tooth, the above-mentioned other end of inertial mass 5 is provided with the cooperating teeth 51 coordinated with internal tooth on wall.
The targeting port 41 formed with insertion, constraint mechanism are movably arranged in targeting port 41 on rotating wheel 4, in other words,
Constraint mechanism is moveable relative to targeting port 41.Constraint mechanism stops respectively with sensor support frame 2 and sensor gear 3
Support, so as to have frictional force between constraint mechanism and sensor support frame 2, constraint mechanism and sensor gear 3 respectively.Work as safety
Band 101 along coiling direction rotate when constraint mechanism and inertial mass 5 only support to prevent inertial mass 5 from coordinating with sensor gear 3.
When rotating wheel 4 rotates along the pull-out direction of safety belt 101, rotating wheel 4 overcomes is maintained at initial bit by constraint mechanism
The frictional force put, so as to drive constraint mechanism together to the pull-out direction of safety belt 101 rotate, now, constraint mechanism not with inertia
Block 5 contacts (i.e. non-contacting position).Such as when safety belt 101 is normally pulled out and worn, constraint mechanism does not connect with inertial mass 5
Touch, rotating wheel 4 overcomes the frictional force of constraint mechanism, constraint mechanism is rotated together with rotating wheel 4.That is, constraint mechanism
It is inoperative when safety belt 101 is normally pulled out and used.When safety belt 101 is quickly extracted out, inertial mass 5 is in inertia force
Effect is lower to engage with the internal tooth of sensor gear 3.
When rotating wheel 4 rotates along the coiling direction of safety belt 101, constraint mechanism is maintained at initial position by frictional force, because
This, rotating wheel 4 is rotated relative to constraint mechanism, and after rotating wheel 4 turns over certain angle, inertial mass 5 contacts with constraint mechanism (to be connect
Touch position).Now, inertial mass 5 is limited relative to rotating wheel 4 towards coiling direction rotation, and inertial mass 5 can not be with sensor tooth
The internal tooth engagement of wheel 3.
Therefore, after safety belt 101 is wound completely, spool 1 drastically rotate stopping and then spool 1 because resilience exists
Pull-out direction is quick and marginally rotates, and the rotation of inertial mass 5 is limited, and therefore, inertial mass 5 can not be with sensor gear 3
Internal tooth engages, thus would not enter " end lock state ".
Webbing take-up device 100 according to embodiments of the present invention, spool 1 is limited by constraint mechanism and drastically rotates stopping
When, inertial mass 5 coordinates with sensor gear 3, so as to enter " end lock state ".
As shown in Figure 1 and Figure 4, constraint mechanism includes：Contact component 61 and friction shell fragment 62, contact component 61 are located at guiding
In mouth 41, contact component 61 only supports with sensor gear 3.Friction shell fragment 62 is located at the proximity sensor support frame of contact component 61
2 side, and the shell fragment 62 that rubs only supports with sensor support frame 2.
According to the alternative embodiment of the present invention, on a side surface of the remote sensor support frame 2 of contact component 61
Provided with brake pad 611, contact component 61 is only supported by brake pad 611 with sensor gear 3.Reference picture 1- Fig. 4, brake pad 611
Can be integrally formed with contact component 61, for example, side table of the brake pad 611 from the proximity sensor gear 3 of contact component 61
Formed facing to close to the direction of sensor gear 3 protrusion, because the area of brake pad 611 is less than the area of contact component 61,
Contact component 61 and the contact area of sensor gear 3 reduce, so as to reduce between contact component 61 and sensor gear 3
Friction.
As shown in figure 4, a side surface of the proximity sensor support frame 2 of contact component 61 is formed with link slot 612, connection
Groove 612 is preferably inwardly concaved by a part for the respective surfaces of contact component 61 and formed, and friction shell fragment 62 is provided with projection 621,
Wherein, projection 621 can be protruded by a part for friction shell fragment 62 towards the direction of contact component 61 forms, and projection 621 coordinates
In link slot 612.Specifically, friction shell fragment 62 can be formed by flexible sheet metal bending, and friction shell fragment 62 blocks
Close in the link slot 612 of contact component 61, so as to rub shell fragment 62 and contact component 61 links into an integrated entity.
Wherein, for projection 621 between the both ends of the length direction of friction shell fragment 62, projection 621 is preferably placed at friction bullet
The center of the length direction of piece 62, the both ends of the length direction for the shell fragment 62 that rubs only are supported with sensor support frame 2, in other words, rubbed
The sliding surface of sensor support frame 2, the friction of the opposite side of contact component 61 are pushed down respectively in the both ends for wiping the length direction of shell fragment 62
Block 611 pushes down sensor gear 3, because friction shell fragment 62 produces the deformation of scheduled volume, in the presence of scheduled volume elastic force, friction
Shell fragment 62 and contact component 61 are maintained at initial position.When rotating wheel 4 rotates, friction shell fragment 62 and contact component 61 are relative
In rotating wheel 4 be static.
There is targeting port 41 in rotating wheel 4, contact component 61 relative in targeting port 41 can slide.Alternatively, targeting port 41
Be formed as the arc opening being coaxially disposed with rotating wheel 4, so as to which contact component 61 and friction shell fragment 62 are relative in rotating wheel 4
The heart rotates.Further, since contact component 61 and friction shell fragment 62 only by peripheral force, so as to not interfere with the stationarity of transmission.Its
In, the circumferential lengths of arc opening coordinate the length in arc opening more than contact component 61, so as to contact component 61 and rub
Wiping shell fragment 62 can move back and forth in arc opening.It is to be appreciated that the concrete shape of targeting port 41 and in rotating wheel 4
On position can specifically be set according to actual requirement, the present invention this is not especially limited.
As shown in Figure 1 and Fig. 2 and Fig. 3 is combined, the both sides of the radial direction along rotating wheel 4 of targeting port 41 are respectively equipped with guiding rib
411, with the stationarity for being further ensured that contact component 61 and the shell fragment 62 that rubs moves.
When V-gear rotates along ribbon pull-out direction, V-gear, which overcomes, is maintained at contact component 61 and friction means
The frictional force of initial position, so as to drive contact component 61 and friction means to be rotated together to ribbon pull-out direction, now, contact
The leading section (for example, right-hand member in Fig. 2 and Fig. 3) of the length direction of part 61 does not contact (i.e. non-contacting position) with inertial mass 5.
When V-gear rotates along ribbon coiling direction, contact component 61 and friction means are maintained at initial by frictional force
Position, therefore, V-gear and contact component 61 and the relative slip of friction shell fragment 62, after V-gear turns over certain angle,
The leading section (for example, right-hand member in Fig. 2 and Fig. 3) of the length direction of contact component 61 contacts (i.e. contact position) with inertial mass 5,
Now one end (for example, right-hand member in Fig. 2 and Fig. 3) of inertial mass 5 is only against between the first locating part 91 and contact component 61,
Inertial mass 5 is constrained by contact component 61, inertial mass 5 is limited relative to V-gear towards coiling direction rotation, inertial mass
5 can not engage with the internal tooth of sensor gear 3.
Therefore, after ribbon is wound completely, spool 1 drastically rotate stopping and then spool 1 because resilience is pulling out
The quick and a small amount of rotation in direction, the rotation of inertial mass 5 are limited, therefore inertial mass 5 can not nibble with the internal tooth of sensor gear 3
Close, thus " end lock state " would not be entered.
