摘要： PROBLEM TO BE SOLVED: To keep a good sliding property so as to improve operability in wearing a seat belt by carrying out double molding so that an outside surface of a sliding part surface alone, on which webbing is slid, is covered by a low friction resin provided with a friction coefficient lower than that of a covering resin. SOLUTION: A through anchor 1 is formed by double molding so that the outside face of a sliding face part 11 alone, on which webbing 10 is slid, in a webbing insertion slot 3 is covered by a low friction resin 9 with a friction coefficient lower than that of a covering resin 4, and as a result, sliding in the sliding face part 11 in the webbing insertion slot 3 is smoothed, and operability can be improved when the webbing is pulled out or wound up.

摘要： PROBLEM TO BE SOLVED: To secure good winding-up characteristics to a retracter for a long time without using smoothing agents or oil agents which cause a sludge adhesions. SOLUTION: A webbing 10 is formed like a belt in general by cross- interweaving warps 11 and 12 and a weft 13. In the webbing 10, a thick part 14 with a fixed dimension A in thickness direction and a thin part 15 with a smaller dimension B in thickness direction than the thick part 14 are set alternately along a width direction (right to left direction in a figure) by using different size of warps 11 and 12. That is, as the size of a warp 11 in the thick part 14 and the size of a warp 12 in the thin part 15 are different, a fixed difference (A-B) is caused between dimensions A and B in thickness direction in the thick part 14 and thin part 15.

摘要： PROBLEM TO BE SOLVED: To reduce a frictional resistance against a webbing guide through usage for a long period of time by installing a range of low-friction strings sewn along the longitudinal direction on the surface of a webbing so as to be dispersively projected. SOLUTION: Low-friction stings 31, which are sewn into a webbing 21 and dispersively projected onto the surface of a webbing body 22, directly come into contact with a sliding surface 24a of a through anchor 24, and thereby its frictional resistance with this through another 24 is reduced. At this time, since the extent of frequency that the webbing body 22 is directly contacted with the sliding surface 24a of the through another 24 is considerably abated, the low-rubbing strings 31 are able to bring its frictional resistance decrement effect into full play. In brief, the webbing 21 is manufactured by a simple manufacturing process that plural lines of low-friction stings 31 are merely sewn along the longitudinal direction so as to be dispersively projected onto the surface of the webbing body, whereby the frictional resistance again the through anchor 24 is reduced through a long period use.

摘要： PROBLEM TO BE SOLVED: To recover and maintain a winding property of a retractor by reducing frictional resistance by sticking a ground fabric impregated with emulsion with a lubricant dispersed in it and a lining cloth consisting of a material from which no emulsion oozes out on each other. SOLUTION: A cleaning pad 1 for a seat belt is structured in two layers by sticking a roughly rectangular ground fabric 2 and a lining cloth 3 on each other. The ground fabric 2 consisting of a material of nonwoven fabric, etc., impregates emulsion with silicon oil 4 which is a lubricant dispersed in a solvent of water, etc. The lining cloth 3 consists of a material of polyethylene, etc., from which no emulsion oozes out. Consequently, it is possible to reduce frictional resistance between a slip guide and a webbing after using for a long period of time and to recover and maintain a winding property of a retractor.

摘要： PROBLEM TO BE SOLVED: To obtain a required winding/drawing-out force independently of a dimension or the like of each winding spring, by obtaining the appropriate winding/drawing-out force at a set winding amount by pre-winding the winding spring with a torque measured. SOLUTION: An outer end of a winding spring 30 is fixed to an upper case 7 so as not to be rotated, and then, the upper case 7 is fixed into a wall member 20 so as not to be rotated. Next, a lower cover 5 is built in the upper case 7, while a retainer 6 is built in so as to lock an inner end of the winding spring 30. Then, a shaft 22 is engaged with the retainer 6. When a motor 21 rotates the shaft 22 so as to pre-wind the winding spring 30, a torque is detected by a torque sensor 23 provided between the motor 21 and the retainer 6. The motor 21 is driven as an adjusting device 25 adjusts such that the detected torque gets equal to a target torque. At the same time, the motor 21 rotates the shaft 22 so as to pre-wind the winding spring 30 through the retainer 6. Accordingly, a feedback operation is performed wholly.

摘要： PURPOSE:To obtain a liner having a low friction coefficient and good wear resistance at low cost by forming a sintered layer of ethylene tetrafluoride resin particles containing filler between yarn of cloth of ethylene tetrafluoride resin yarn or union cloth thereof with another fiber having the same heat resistance. CONSTITUTION:Warp 11 of ethylene tetrafluoride resin fiber and weft 12 of another fiber having the same heat resistance as ethylene tetrafluoride resin fiber are fabricated in such a manner that warp 11 appears greater than weft 12 on a slide surface side. The cloth 10 is laid in a container with the slide surface thereof upside, and after water is poured and powder mixture of ethylene tetrafluoride resin and filler is dispersed, it is uniformly drained and pressed and heated in a molding die. Therefore, sintered particles 15 are fusingly attached between warp 11 and weft 12 to form sintered layers 16, 17, so that the structure can be made at low cost, having a low friction coefficient due to resin and good wear resistance due to filler.
