Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 9, the present invention discloses a height adjuster for a seat belt, including:
a guide rail 100, the guide rail 100 being provided with a rack 140 along a length direction thereof;
the sliding block 200 is slidably connected with the guide rail 100, a gear 330 meshed with the rack 140 is arranged on the sliding block 200, and the gear 330 rotates to adjust the position of the sliding block 200 on the guide rail 100;
an adjustment assembly 300, comprising: the fixed wheel 310 is fixedly connected with the sliding block 200, and the fixed wheel 310 is in clearance fit with the gear 330; an abutment 360, said abutment 360 having a first position and a second position; the trigger piece 340 is fixedly connected with the abutting piece 360, the trigger piece 340 is rotatably connected with the sliding block 200, and the trigger piece 340 is rotated to enable the abutting piece 360 to be switched between a first position and a second position;
when the abutment 360 is in the first position, the abutment 360 is disengaged from the gear 330 and/or the fixed wheel 310; when the abutting piece 360 is in the second position, the abutting piece 360 abuts against the gear 330 and the fixed wheel 310 at the same time to lock the rotation of the gear 330 relative to the fixed wheel 310.
As shown in fig. 2, in the present embodiment, the gear 330 is engaged with the rack 140 to realize the sliding of the slider 200 relative to the guide rail 100, so as to achieve the purpose of height adjustment, and realize the stepless adjustment of the height of the seat belt. Compared with the conventional multi-stage regulation, the regulation range of the device is wider.
More importantly, the present application is provided with the adjusting assembly 300, and the adjusting assembly 300 comprises the fixed wheel 310 and the abutting member 360, so that the locking strength of the height adjuster can be increased along with the increase of the stress on the safety belt.
Specifically, as shown in fig. 9, when the height of the safety belt needs to be adjusted, the abutting piece 360 is not abutted to the fixed wheel 310 and the gear 330 at the same time, so that the gear 330 can rotate freely, and further, the height can be adjusted to a preset height; when the locking is needed, the abutting member 360 can be placed at the second position, and at this time, the abutting member 360 abuts against the gear 330 and the fixed wheel 310 at the same time, since the fixed wheel 310 is fixedly connected with the slider 200 and cannot rotate, the abutting member 360 abuts against the rotation of the gear 330 effectively, and the locking of the position of the slider 200 on the guide rail 100 is further realized.
It should be noted that, this embodiment realizes the locking through the extrusion of tight fitting piece 360 by tight pulley 310 and gear 330, therefore, when gear 330 is bigger to the extrusion dynamics of tight fitting piece 360, its locking dynamics also increases thereupon, and then can avoid when the accident, danger that height adjuster locking dynamics is not enough and became invalid causes.
Further, a circular hole is formed in the middle of the gear 330, and the fixed wheel 310 is arranged in the circular hole and is in clearance fit with the gear 330;

Specifically, as shown in fig. 3 to 5, the abutment 360 is disposed in the notch 311, when the abutment 360 is at the first position, the abutment 360 is at the area of the first connection end 312a, and the gear 330 cannot press the abutment 360, so that the abutment 360 does not lock the gear 330; when the abutting piece 360 is located at the second position, the abutting piece 360 is located at the area of the second connecting end 312b, and at this time, the gear 330 and the fixed wheel 310 simultaneously press the abutting piece 360, so that the gear 330 is locked.
It should be noted that the abutment member 360 in this embodiment can lock the gear 330 from rotating in the clockwise or counterclockwise direction, and can only lock the gear from rotating in one direction, but not in the other direction. In the actual use process of the safety belt, the direction of the force applied to the height adjuster is inclined downward, and the height adjuster is not applied with an upward force, so that the rotation in one direction only needs to be locked, and when the gear 330 rotates in the direction, the height adjuster is adjusted downward.
Further, the abutting piece 360 is arranged in a cylinder;
the distance from the first connection end 312a to the inner wall of the gear 330 is greater than the diameter of the abutment piece 360, and the distance from the second connection end 312b to the inner wall of the gear 330 is less than the diameter of the abutment piece 360.
