[0039] With reference to FIGS. 1 to 4 and 9, the first webbing buckle 21 and the second webbing buckle 22 are movably connected to the curved guiding section 111 of the two webbing adjustment buckles 10, respectively. The first webbing buckle 21 and the second webbing buckle 22 are capable of naturally rotating and hanging down on the curved guiding section 111 to a front side of the webbing 2 by gravity, respectively, and reduce interference when the first webbing buckle 21 rotates with the second webbing buckle 22 and enhance smoothness when the first webbing buckle 21 and the second webbing buckle 22 naturally rotate and sag on the curved guiding section 111 by gravity by the curved shape of the curved guiding section 111.

[0040] With reference to FIGS. 1, 2, 4, and 9, the first webbing buckle 21 has a first connecting webbing 211 and a first buckle 212. The first buckle 212 is connected to one end of the first connecting webbing 211. Another end of the first connecting webbing 211 is wrapped around one of the buckle connections 11, and thereby the first webbing buckle 21 can rotate on the buckle connection 11. The second webbing buckle 22 has a second connecting webbing 221 and a second buckle 222. The second buckle 222 is connected to one end of the second connecting webbing 221. Another end of the second connecting webbing 221 is wrapped around another one of the buckle connections 11, and thereby the second webbing buckle 22 can rotate on the buckle connection 11. The first buckle 212 and the second buckle 222 can be respectively a male buckle and a female buckle configured to be locked together. The male buckle and the female buckle can be selected from any known product, and structure thereof would be omitted from description.

[0041] With reference to FIGS. 1, 2, and 4, in the first buckle 21 and the second buckle 22, the first connecting webbing 211 and the second connecting webbing 221 both are fixed-length belts, or the first connecting webbing 211 and the second connecting webbing 221 are each a length-adjustable belt having a position adjustment component 213 and a belt body mounted in the position adjustment component 213. Alternatively, with reference to FIG. 3, one of the first connecting webbing 211 and the second connecting webbing 221 is a fixed-length belt; the other one of the first connecting webbing 211 and the second connecting webbing 221 is a length-adjustable belt having a position adjustment component 213 and a belt body mounted in the position adjustment component 213. Wherein, with one or both of the first connecting webbing 211 and the second connecting webbing 221 being length-adjustable, the user can adjust the length of the connecting buckle assembly 20 according to the user's body shape. With reference to FIGS. 1, 2, 4, and 9, when the protection reinforcing device 1 is applied to the multi-point seat belt system of the seat of the vehicle, taking the application to the four-point seat belt system A and the five-point seat belt system A1 as examples. When the user sits on the seat, the two webbings 2 connected to the retractor 3 are wrapped around both the right and left sides of the user's body, and the seat buckle 41 and the tongue 42 connected to the two webbings 2 are locked to each other, and thereby the seat buckle assembly 4/4A is located in front of the user's abdomen. After that, the first webbing buckle 21 and the second webbing buckle 22 are locked to each other and horizontally connected between the two webbings 2 to provide reinforcement between the two webbings 2.

[0042] The first webbing buckle 21 and the second webbing buckle 22 can be mounted on the two webbings 2 by the two webbing adjustment buckles 10, respectively, allowing the user to adjust the height position and the positioning of the two webbing adjustment buckles 10 on the two webbings 2 to fit the user's body shape. Therefore, the first webbing buckle 21 and the second webbing buckle 22 are locked to each other and transversally connected between the two webbings 2, and horizontally located in front of the user's abdomen to provide an auxiliary safety protection effect for the user. During emergency deceleration or braking of the vehicle, the retractor 3 retracts the two webbings 2 wrapped around the user's body on the seat. When the user on the seat moves forward because of inertia force, the user's upper body won't slide over the two webbings 2 at both right and left sides and tilt forward between the two webbings 2. Therefore, the protection reinforcing device 1 can provide excellent auxiliary safety protection and reinforcement in the multi-point seat belt system.

[0043] With reference to FIGS. 1, 2, and 9, when disengaging the first webbing buckle 21 and the second webbing buckle 22, the first webbing buckle 21 and the second webbing buckle 22 are capable of naturally rotating and hanging down respectively on the curved guiding section 111 to a front side of the webbing 2 by gravity to reduce interference with the user's movement.

[0044] Wherein, the protection reinforcing device 1 reduces interference when the first webbing buckle 21 rotates with the second webbing buckle 22 and enhances smoothness when the first webbing buckle 21 and the second webbing buckle 22 naturally rotate and sag on the curved guiding section 111 by gravity with the curved-shape of the curved guiding section 111.

[0045] In addition, the protection reinforcing device 1 utilizes a gap between the buckle connection 11 and the positioning section 12, the buckle connection 11 located in front of the webbing 12, and a step between the buckle connection 11 and the webbing 2 to provide an appropriate space for the movement of the first webbing buckle 21 and the second webbing buckle 22, respectively. Therefore, the protection reinforcing device 1 enhances smoothness when the first webbing buckle 21 and the second webbing buckle 22 rotate at the buckle connection 11, and reduces interference of the webbing adjustment buckle 10 and the webbing 2 with the first webbing buckle 21 and the second webbing buckle 22 when rotating.

[0046] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
