On the right side ofFig. 1 , warps are shown as being spaced apart in the weft direction. On the lowermost side ofFig. 1 , the depiction of main warps is omitted.Fig. 2a is a sectional view taken along the warp direction showing the engagement relationship between main warps M and wefts W, and is a sectional view taken along line IIa-IIa ofFig. 3 .Figs. 2b to 2e are sectional views taken along the warp direction showing the engagement relationship between thin warps A to C and wefts a to c.Fig. 3 is a plan view of abase 11 consisting of main warps M and wefts W.Figs. 4a to 4d are enlarged end views of sections taken along lines IVa-IVa, IVb-IVb, IVc-IVc, and IVd-IVd, ofFigs. 2b to 2e . - The
webbing 10 has abase 11 and many thin warps A to C and a to c woven into thebase 11. Thewebbing 10 has a belt-like shape elongate in the extending direction of the main warps M and the thin warps A to C and a to c. - The
base 11 is made by interlacing many thick main warps M parallel to each other and many thin wefts W parallel to each other. The warps and the wefts extend in the orthogonal direction. Although the wefts W are designated byreference signs 1 to 4, this is for showing the order of arrangement, and the wefts W are the same yarn. Many wefts W are arranged in the order of 1, 2, 3, 4, 1, 2, 3, 4 ... in the longitudinal direction of thewebbing 10. - The intervals between adjacent wefts W are equal, and the intervals between adjacent main warps M are also equal.
- The main warps M have a fineness of 1000 to 3000 denier, preferably 1000 to 1500 denier. The thin wefts W have a fineness of 250 to 1500 denier, preferably 500 to 750 denier. The thin warps A to C and a to c have a fineness of 250 to 1500 denier, preferably 250 to 500 denier.
- In the
base 11 of this embodiment, as shown inFig. 2a andFig. 3 , the thin wefts W are disposed parallel to each other on the same plane. The main warps M meander so as to pass over odd-numberedwefts wefts wefts wefts wefts weft 3, and to again pass overweft 4 and thenext weft 1. - On the upper side of the webbing, the thin warps A, B, and C cover the main warps M of the
base 11. On the lower side of the webbing, the thin warps a, b, and c cover the main warps M of thebase 11. - The thin warps A, B, and C are arranged in this order repeatedly, that is, in the order of A, B, C, A, B, C, A, B, C ... from right to left in
Fig. 1 ,Fig. 4a to Fig. 4d (that is, from one side edge to the other side edge of the webbing). The region where the thin warps A, B, and C are repeated in this order may be partial. - The thin warps a, b, and c are also arranged in this order repeatedly, that is, in the order of a, b, c, a, b, c, a, b, c ... from right to left in
Fig. 1 ,Fig. 4a to Fig. 4d . - Of the thin warps A, B, and C covering the main warps M on the upper side of the webbing, the warps A and C pass under the
second wefts 2 so as to be in contact with thewefts 2, and pass over the other, first, third, andfourth wefts Fig. 2b . Although depiction is omitted inFig. 2b to make the figure clear, the main warps M are interposed between thewefts Fig. 4a, Fig. 4c, and Fig. 4d . - Of the thin warps A, B, and C covering the main warps M on the upper side of the webbing, the warps B pass under the
fourth wefts 4 so as to be in contact with thewefts 4, and pass over the other, first, second, andthird wefts Fig. 2c . Although depiction is omitted inFig. 2c , the main warps M are interposed between thewefts 1 to 3 and the thin warps B as shown inFig. 4a to Fig. 4c . The above ordinal numbers are for convenience of description. The present invention is not limited to this, and weaving may be performed at unequal intervals without repeating. - Of the thin warps a, b, and c covering the main warps M on the lower side of the webbing, the warps a and c pass over the
third wefts 3 so as to be in contact with thewefts 3, and pass under the other, first, second, andfourth wefts Fig. 2d . Although depiction is omitted inFig. 2d , the main warps M are interposed between thewefts Fig. 4a, Fig. 4b, and Fig. 4d . - Of the thin warps a, b, and c covering the main warps M on the lower side of the webbing, the warps b pass over the
first wefts 1 so as to be in contact with thewefts 1, and pass under the other, second, third, andfourth wefts Fig. 2e . Although depiction is omitted inFig. 2e , the main warps M are interposed between thewefts 2 to 4 and the thin warps b as shown inFig. 4b to Fig. 4d . -
Fig. 4a to Fig. 4d respectively show sections taken alongwefts webbing 10. As described above, by weaving thin warps A to C and a to c into a base 11 made by interlacing wefts W (1 to 4) and main warps M, the wefts W and the main warps M of the base 11 are integrated. Since, on the upper side of thewebbing 10, the thin warps A to C cover a large part of the upper surface of the webbing, the texture of the upper surface of thewebbing 10 is smooth. For example, on the upper side of thewebbing 10, the thin warps A to C cover a large part of the upper surface of the webbing except for the tops t (parts most distant from the wefts W) of the main warps M. - Since, on the lower side of the
webbing 10, the thin warps a to c cover a large part of the lower surface of the webbing, the texture of the lower surface of thewebbing 10 is smooth. For example, on the lower side of thewebbing 10, the thin warps a to c cover a large part of the lower surface of the webbing except for the tops t of the main warps M. Since thewebbing 10 has thick main warps M, it has high strength. The thin warps A to C and a to c may be impregnated or coated with light resisting agent. - In the above embodiment, three thin warps A to C and three thin warps a to c are disposed between each adjacent pair of main warps M. However, the present invention is not limited to this.

webbing 20 has a base 21 consisting of main warps M1 to M4 and wefts W (1 to 4), and first thin warps e to h and second thin warps E to H woven into thebase 21. Although the main warps M are designated withsubscripts 1 to 4 inFigs. 5 to 9 , this is for showing the order of arrangement of the main warps M, and the main warps M1 to M4 are of the same type. - As shown in
Figs. 8 and 9 , the base 21 used in this embodiment is made by rib-weaving main warps M (M1 to M4) and wefts W. That is, as shown inFigs. 8 and 9 , the main warps M1 pass over thewefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts wefts - In the above rib weaving, the main warps M alternately pass over and under two wefts W. However, the present invention is not limited to this. For example, the main warps M may alternately pass over and under three wefts W.
- In this embodiment, the first thin warps e to h and the second thin warps E to H are used. The first and second thin warps e to h and E to H are arranged in this order from one side edge (the right side of
Figs. 5 and6 andFig. 7b ) to the other side edge (the left side ofFig. 5 ,Fig. 6 andFig. 7b ) of thewebbing 20, between main warps M1 and M2, between main warps M2 and M3, between main warps M3 and M4, and between main warps M4 and M1. - The first thin warps e and g pass over the odd-numbered
wefts wefts wefts wefts wefts 1 to 4 at their parts intersecting with thewefts 1 to 4. - The second thin warps E to H are woven into the base 21 so as to overlap the first thin warps e to h. The second thin warps E pass over the
wefts wefts wefts wefts wefts wefts wefts wefts - The second thin warps E to H overlap the first thin warps e to h, and pass on the farther side of the thin warps e to h from the
base 21. The thin warps E to H are woven such that the positions (the heights from the wefts W) of their tops are substantially the same as those of the tops of the main warps M1 to M4, and the main warps M1 to M4 and the second thin warps E to H are flush with each other. - Specifically, if the distance (height) from the center in the thickness direction of the webbing 20 (the centers of the wefts W) to the tops of the main warps M1 to M4 is denoted as X1, and the distance (height) from the center in the thickness direction of the webbing 20 (the center of the wefts W) to the tops of the thin warps E to H is denoted as X2, the distance X2 is 80 to 120%, preferably 95 to 105% of the distance X1.
- Since, on both the upper and lower sides of the
webbing 20, the surface of thewebbing 20 is formed by the thick main warps M1 to M4 and the second thin warps E to H disposed therebetween, and the main warps M1 to M4 and the second thin warps E to H are flush with each other, the texture of the surface of thewebbing 20 is smooth. In addition, since the main warps M1 to M4 are used, the strength of thewebbing 20 is high. The thin warps E to H may be impregnated or coated with light resisting agent. - In this embodiment, the main warps M1 to M4 have a fineness of about 1000 to 3000 denier, preferably about 1000 to 1500 denier. The thin warps E to H and e to h are of the same denier, and have a fineness of about 250 to 1500 denier, preferably about 250 to 500 denier. The wefts W have a fineness of about 250 to 750 denier, preferably about 500 to 750 denier.
- In this embodiment, four thin warps e to h and four thin warps E to H are disposed in each space between the main warps M1, M2, M3, and M4. However, the present invention is not limited to this. One or more thin warps and one or more thin warps, preferably three to four thin warps and three to four thin warps may be disposed in each space between the main warps M1, M2, M3, and M4.
- The webbing of the present invention is suitable as a webbing of a seat belt apparatus for an automobile. A seat belt apparatus for an automobile includes a webbing, a retractor for retracting the webbing, a tongue to which the webbing is inserted or connected, and a buckle to and from which the tongue is attached and detached.
- The webbing of the present invention can be used in various seat belt apparatuses such as those for aircraft, ships, and game machines.
