According to one embodiment of the invention, the bolt 4 can be connected with the retractor fixing bracket 5 into a whole in a projection welding mode and then is in threaded connection with the nut 8 and the safety belt retractor 7.
The retractor fixing support 5 comprises a retractor positioning hole 9, a bolt mounting hole 10 and a paint liquid guiding groove 11. When the safety belt retractor 7 is assembled, the positioning pin on the retractor is inserted into the retractor positioning hole 9, so that the functions of pre-positioning and rotation limiting are achieved. The bolt mounting hole 10 is coaxially connected to the bolt 4. Coiler 5 lower extremes of fixed bolster are equipped with outstanding muscle, for lacquer liquid derives groove 11, and when the effect in this groove was for whole swimming lacquer after the seat skeleton welding was accomplished, the lacquer liquid can be derived from the lower extreme, prevents to stay trace and abnormal sound.
The retractor fixing bracket 5 is welded to the seat back frame 1.
After the safety belt 6 is pulled out from the safety belt retractor 7, the upper end of the safety belt passes through the safety belt guide support 2 and the safety belt guide cover 3, so that the safety belt 6 can be freely drawn out and retracted.
The seat belt guide bracket 2 is welded to a seat back pipe frame 12 of the seat back frame 1. The top of the safety belt guide support 2 is connected with the safety belt guide cover 3 in a clamping way.
The safety belt guide support 2 comprises a pipe frame insertion groove 13, a pipe frame lapping structure 14, a hood cover releasing claw 15, a hood cover mounting positioning hole 16 and a 180-degree flanging 17. The pipe frame overlapping structure 14 is welded with the seat back pipe frame 12.
The safety belt guide cover 3 comprises a mounting limiting structure 18, a forward turning resisting structure 19, a safety belt sliding groove 20, an anti-torsion boss 21, a buckle I22 and a buckle II 23. The buckle I22 can be clamped and fixed with the buckle II 23. The mounting stops 18 are insertable into the cover mounting location holes 16.
The process of installing the safety belt 6 into the safety belt guide cover 3 comprises the following steps:
the safety belt guide cover 3 is firstly opened left and right, so that the buckle I22 and the buckle II 23 are in a non-clamping state, and at the moment, the safety belt 6 enters a channel through elastic deformation of a plastic part. The safety belt 6 is inserted into the safety belt sliding groove 20 from the passage, and then the safety belt guide cover 3 is extruded left and right, so that the buckle I22 and the buckle II 23 are respectively and firmly clamped. The anti-twist bosses 21 serve to prevent the upper end of the belt guide cover 3 from twisting apart. When the safety belt guide support 2 is assembled with the safety belt guide cover 3, the installation limiting structure 18 is firstly inserted into the cover installation positioning hole 16, and the safety belt guide cover 3 is pressed downwards, so that the anti-forward-turning structure 19 is pressed below the anti-cover-falling claw 15. The seat back pipe frame 12 is inserted into the pipe frame insertion groove 13, and the webbing guide bracket 2 is welded to the seat back pipe frame 12. The tube frame overlapping structure 14 is overlapped on the seat back tube frame 12 at the rear and then welded. The 180-degree flanging 17 is used for preventing the safety belt guide support 2 from cutting off the safety belt after the safety belt guide cover 3 is separated from the safety belt guide support 2.
The safety belt fixing and guiding structure in the middle of the automobile seat is simple and convenient to install, and 3, the safety belt guiding cover is fixed firmly, so that the safety belt breaking and failure risk is avoided; the pulling and retracting movement of the safety belt is smooth without clamping stagnation; the connecting strength is high, and the safety is good.
