As shown in fig. 27 and 30, in a seventh preferred embodiment of the webbing height adjusting device 1G, the folding positioning structure 30G includes a folding connector 31 and a combining portion 32, the folding connector 31 has a base plate portion 310, a central hole 311 is formed in the base plate portion 310, two abutting convex columns 314 protruding rearward are formed on the back surface of the base plate portion 310, so that the folding connector 31 and the positioning member 11 of the upper ring member 10 can be installed together on one side of the seat in the vehicle by a locking element 6, the base plate portion 310 of the folding connector 31 is fixed on the side surface of the positioning member 11, the two abutting convex columns 314 abut against the positioning member 11, and the locking assembly 20G and the folding positioning structure 30G cannot swing relatively.

The usage of the seventh preferred embodiment of the webbing height adjusting device 1G is substantially the same as that of the fifth preferred embodiment of the webbing height adjusting device 1E (shown in fig. 16-22) in the previous disclosure, and will not be described again.

Referring to fig. 31 and 32, an eighth preferred embodiment of the webbing height adjusting device 1H according to the present invention is disclosed, wherein the webbing height adjusting device 1H also includes an upper ring member 10, a locking member 20H and a folding positioning structure 30H. Compared with the sixth preferred embodiment (shown in fig. 23 to 26) of the disclosed webbing height adjusting device 1F, the composition of the eighth preferred embodiment of the webbing height adjusting device 1H is substantially the same, and both of them have the function that the locking assemblies 20F and 20H can selectively hook the folding positioning structures 30F and 30H positioned on the side surface of the upper ring member 10, and the same parts are not described herein again.

As shown in fig. 31 and 32, the folding positioning structure 30H of the eighth preferred embodiment of the webbing height adjusting device 1H also includes a folding connecting member 31 and a combining portion 32, the combining portion 32 is disposed at a lower side of the folding connecting member 31 and can selectively hook the folding connecting portion 24 of the outer cover 23, so that the locking assembly 20H can be hooked and positioned at the side of the upper ring member 10 by combining the folding positioning structure 30H.

The difference between the eighth preferred embodiment of the webbing height adjustment device 1H and the sixth preferred embodiment of the front-uncovered webbing height adjustment device 1F (shown in fig. 23-26) is that in the eighth preferred embodiment of the webbing height adjustment device 1H, the combining portion 32 forms a transverse elongated protrusion, and the bottom end of the foldable connecting portion 24 of the outer cover 23 forms an elongated groove 236 corresponding to the shape of the combining portion 32, so that the elongated protrusion 32 can be locked in the elongated groove 236 at the bottom end of the foldable connecting portion 24 of the outer cover 23. In addition, the connecting frame portion 212 of the movable frame plate 21 is externally connected with a flexible connecting band, and then the connecting band is used to assemble a connecting member, and the webbing 2 is inserted into the connecting member, so that the connecting frame portion 212 of the movable frame plate 21 is indirectly connected with the webbing 2 through the combination of the connecting band 25 and the connecting member 26 which are connected in series.

The usage of the eighth preferred embodiment of the webbing height adjusting device 1H is substantially the same as that of the sixth preferred embodiment of the webbing height adjusting device 1F (shown in fig. 23 to 26) in the previous disclosure, and will not be described again.

As can be seen from the above description of various preferred embodiments of the webbing height adjusting apparatus according to the present invention, the webbing height adjusting apparatus can be applied to a seat belt system in a vehicle, and provides a function of continuously adjusting the height position of an upper positioning point of a webbing, and has a simple operation and an automatic locking function. When the device for adjusting the height of the mesh belt is not used, the locking component can automatically rise along with the furling of the mesh belt and is relatively buckled and combined with the folding and positioning structure arranged on the side surface of the upper ring component, so that the height of the mesh belt can be folded above one side of the seat without occupying space, and the mesh belt is in an unlocking state capable of being freely stretched, thereby being the invention with great industrial utilization value.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
