Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 3 is the structural representation of the belt guide loop in the utility model embodiment.Fig. 4 is the view of spring-compressed in the belt guide loop in Fig. 3.Fig. 5 is the structural representation of the seat belt apparatus in the utility model embodiment.Fig. 6 is the view of spring-compressed in the seat belt apparatus in Fig. 5.Fig. 7 is the structural representation of the compressive plate in the utility model embodiment.Fig. 8 is the scheme of installation of compressive plate in the utility model embodiment and guide ring body.The belt guide loop that the utility model embodiment provides is applicable to seat belt apparatus and the automobile of Multiple Type.

The belt guide loop 3 that the utility model provides, comprises set collar 10, guide ring body 20, compressive plate 30 and spring 40; Described set collar 10 is fixed in the outside of described guide ring body 20; Described compressive plate 30 runs through that to be arranged at described guide ring body 20 inner, the first end 31 of described compressive plate 30 is articulated with the inwall of described guide ring body 20, to make the second end 32 relative with described first end 31 can rotate around described first end 31, and described spring 40 can with described the second end 32 around the rotary compression of described first end 31 or elongation.

Wherein, above-mentioned set collar 10 is connected for being fixed with center body pillar inner panel, and after fixing, belt guide loop 3 only can rotate around set collar 10, plays the effect be fixedly connected with center body pillar backplate.

The material of compressive plate 30 can be rigid plastic usually, and while having higher-strength, deadweight is lighter.The first end 31 of compressive plate 30 is articulated with the side of guide ring body 20 inwall, the second end 32 connects stiffness spring 40, compressive plate 30 plane plays the effect of support safety band 2, when automobile collides, safety strap 2 extrudes compressive plate 30, compressive plate 30 Compress Spring 40, makes the plane residing for safety strap 2 by downward-sloping angle boil down to Plane Angle, thus prevents safety strap 2 to the slip of guide ring body 20 one end, clustering phenomena occurring due to guide ring body 20 angular slope.

As an embodiment of the present utility model, as shown in Figure 7, the first end 31 of compressive plate 30 can be set to be with porose axle, and revolving bar 50 can be inserted in this hole axle, and hole axle is stretched out at the two ends of revolving bar 50.Fig. 8 is the scheme of installation of compressive plate 30 in the present embodiment and guide ring body 20.Have at a side of guide ring body 20 inwall the groove that two side has hole, the two ends of revolving bar 50 are inserted in the hole of this groove two side, thus compressive plate 30 can be rotated around revolving bar 50.

In another embodiment, guide ring body 20 has the Internal periphery of quadrangle.Further, as shown in Figure 3 and Figure 4, guide ring body 20 has trapezoidal Internal periphery, described first end 31 is articulated with the upper base of described trapezoidal Internal periphery, described the second end 32 is connected to going to the bottom of described trapezoidal Internal periphery, and described spring 40 connects the waist of described the second end 32 and described trapezoidal Internal periphery.The guide ring body 20 with this trapezoidal Internal periphery can play the directional tagging to safety strap 2 preferably, conducts oneself with dignity comparatively light and intensity is higher simultaneously.

In the above-described embodiments, the stiffness coefficient of spring 40 can be 1000-2000N/mm.Spring 40 one end is fixed on the side of guide ring body 20 inwall, the other end is fixed on the second end 32 of compressive plate 30, thus become compressive state when colliding from natural extended configuration, make compressive plate 30 plane gradually become level by inclination, thus prevent safety strap 2 from the generation clustering phenomena that glides occurring.

In the above-described embodiments, the surface of described compressive plate 30 can also be provided with guiding convex tendon, the setting of guiding convex tendon, the contact between safety strap and compressive plate 30 is made to become the contact of face and line from the contact in face and face, substantially reduce friction force therebetween, improve the traveling comfort of occupant, safety strap 2 is also not easy to be cut off simultaneously.

The utility model is a kind of seat belt apparatus 4 also, as shown in Figure 5 and Figure 6, be included in the safety strap 2 in emergency circumstances occupant retrained, the Webbing retractor that described safety strap 2 is reeled and above-mentioned belt guide loop 3, belt guide loop 3 guides the described safety strap 2 pulled out from this Webbing retractor towards occupant's shoulder direction, described safety strap 2 is inner through described belt guide loop 3.When automobile generation head-on crash; occupant travels forward and pulls safety strap 2; safety strap 2 extrudes and is compressed by compressive plate 30; by heeling condition boil down to horizontality; safety strap 2 is prevented to assemble together owing to being tilted to slip down to; thus ensure that the normal use of safety strap 2, and then protection occupant breast compressions amount does not exceed standard, and plays the effect of protection occupant.

Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
