Description
Technical field
The present invention relates to the seat harness sideband of the characteristic in a kind of preamble that comprises claim 1 or 6 and the method for making said seat harness sideband.
Background technology
Seat harness for example is used for motor vehicle, aircraft and other mobile device in order to the constraint occupant.In order to realize its function, seat harness need show preset tensile strength.And, as far as possible little stop and occupant's clothes can be damaged that seat harness should comprise surface and the soft edge that shows as far as possible little frictional force usually for what make that the occupant receives seat harness.
The seat harness sideband comprises many warps, and said warp moves with longitudinal direction, and said warp is connected to each other through the parallel that is transverse to said warp operation.In weaving process, parallel utilizes the side process said warp travels (shot) of latitude pin from the safety belt sideband, and clamps with locker line (catch thread) at opposite side, makes that parallel can not drawn back with it when regaining the latitude pin.Load is in the situation of seat harness sideband having an accident, and warp is the bearing load line, so warp need have certain tensile strength, and parallel carries less load and mainly form the surface of safety belt sideband.Therefore, parallel should show than the better surface characteristic of warp, and still, more soft surface possibly show the tensile strength more weak than warp.
Can know a kind of safety belt sideband from EP 1 514 962 A2, comprise warp at its fringe region, said warp shows the shrinkage character different with the warp of central area.In shuttling back and forth in succession, the warp of parallel and varying number interweaves, and makes that some warp (for example only shuttling back and forth at per the 4th or the 5th) is by the parallel pitch of the laps in the edge region.After weaving the safety belt sideband, the safety belt sideband is through heat treatment, during heating treatment, and through intentionally the warp in the fringe region is shunk the formation soft edge differently.
And the warp in the known seat harness sideband in the fringe region is designed to much thinner than the warp of central area.Because the thinner warp of fringe region, the edge of seat harness sideband are more soft, and the surface of seat harness sideband is more even, therefore, when seat harness sideband and edge friction, the sawing effect of seat harness sideband is weakened greatly.
Summary of the invention
The purpose of this invention is to provide a kind of improved seat harness sideband that comprises soft edge, and a kind of method that is used to make said seat harness sideband.
In order to realize this purpose, the present invention proposes a kind of seat harness sideband and a kind of method that comprises the characteristic of claim 6 that comprises the characteristic of claim 1.
Be appreciated that other preferred embodiment of the present invention by dependent claims, accompanying drawing and related description.
In order to realize above-mentioned target, the present invention proposes the locker line and is placed between the warp, and the locker line is covered by parallel and/or warp on the surface towards the seat harness sideband.
Locker line in the seat harness sideband itself has in weaving process the function that parallel is remained on rollback point; Here it is, and why the locker line must have certain tensile strength, and the locker line can not be torn in weaving process and make weaving process have to so interrupt for this reason.All of a sudden, appearing at surperficial locker alignment turns up to the important common influence of hardness generation at edge.Because the function of locker line, the characteristic of locker line is different from the characteristic of parallel, and therefore because the locker line that on the surface between the parallel, occurs, it is very inhomogeneous that the surface becomes, and when for example edge and occupant's clothes rubbed, the sawing effect at edge was enhanced.According to solution of the present invention, owing to the locker line is placed between the warp, and by parallel and/or warp covering, edge surface is only limited parallel and/or warp now.Therefore see the locker line no longer from the outside.Another advantage of the present invention is, two edges of seat harness sideband therefore much at one, even adopt the locker line only to be arranged on the weaving technology that a side and parallel only insert from a side.
Therefore the shortcoming of the non-uniform face of seat harness sideband is that mainly they are worn and torn differently, and the seat harness sideband provides the visual impression of a lesser value to the beholder after long-term wearing and tearing.And when the safety belt sideband was installed with the misalignment mode, inhomogeneous edge may make seat belt retractor during the withdrawal of seat harness sideband is moved and extracted action out, produce undesirable noise.Thus, when being installed in the safety belt sideband in the seat belt retractor, installed improperly with the misalignment mode, needed to adopt the method for specific increase cost in order to prevent the seat harness sideband.Inhomogeneous edge also causes the seat harness sideband when deflector is pulled out, to produce the safety belt load-bearing surface quilt wearing and tearing unevenly that extra noise, the retracting force that causes the seat harness sideband and extraction power change unfriendly and causes deflector.
Description of drawings
To the present invention more specifically be described based on preferred embodiment below.Accompanying drawing only illustrates the seat harness sideband that comprises the locker line among the present invention, and said locker line is placed between the warp.
The specific embodiment
The seat harness sideband can be further divided into core A and marginal portion B.In core A, be provided with warp 1, it is 900 to 2100 dtexs (dtex) that warp 1 has line style, and is designed to many monofilament-type (multifilaments), and it comprises the monofilament of not twisted with the fingers or twist with the fingers becoming to go up to the monofilament of every meter length 150 sth. made by twisting (twist).Warp 1 has the function that absorbs the pulling force that produces when having an accident, and therefore, warp 1 is tough especially and therefore also harder relatively.Be provided with thinner warp 3 among the part B on the edge of, it is 400 to 1100 dtexs that said warp 3 has line style, and warp 3 also is designed to many monofilament-type, comprises for example 28 monofilament.Said monofilament is twisted together to form and goes up to every meter length 150 times (time).
And, be provided with parallel 2, when weaving the safety belt sideband, parallel is shuttled back and forth from a side, through the shed open that forms by the two- layer warp 1 and 3 that is oriented relative to one another to angular alignment with the latitude pin.At the edge of seat harness sideband, utilize locker line 5 that parallel 2 is clamped, and parallel 2 utilize the knitting needle crocheting with locker line 5.Parallel 2 also is to be designed to many monofilament-type, and it has line style is 280 to 1100 dtexs, and comprises that for example 96 monofilament, said 96 monofilament are twisted together every meter length of formation 130 times.Because the quantity of monofilament is very big, parallel 2 moves especially certainly, makes to utilize this parallel can obtain particularly soft and surperficial uniformly.Locker line 5 also is designed to many monofilament-type, and to have line style be 280 dtexs, and comprises that 48 monofilament twist with the fingers for every meter 80.And, being provided with lock-in line 4, lock-in line 4 is directed with locker line 5, and produces the better uniformity of the composite material for weaving of seat harness sideband.
As shown in Figure 1; Warp 3 thinner among the B of marginal portion interweaves to form two- layer 6 and 7 with parallel 2; Have in the following manner the Weaving pattern that forms respectively, be the group III of three warps 3 in a side, be that the group I of a warp 3 is alternately passed by parallel 2 at opposite side.Parallel 2 is independent single line, and in weaving process, parallel 2 is directed with the form of cyclic movement, and realizes the interconnection of warp 1 and 3 thus, and at least also forms the major part on the surface of seat harness sideband.
Second shuttle back and forth at each; Parallel 2 only is directed through warp 3; And one after the other pulling locker line 5 is to the B of marginal portion when moving backward, and in accomplishing woven seat harness sideband, locker line 5 will stay between the warp 3 and covered by parallel 2 towards the surface.Because core A middle longitude 1 weaves and is different among the B of marginal portion thin warp 3 to parallel 2 and weaves to parallel 2, locker line 5 preferably only is drawn into marginal portion B, the edge of the core A between the thin warp 3 of as many as.After said the shuttling back and forth of parallel 2; Shuttle back and forth through at least a portion warp 3 at next equator 2 that shuttles back and forth, preferably pass through the one deck in the layer 6 or 7, parallel 2 is clamped by locker line 5 subsequently; And when moving backward, parallel 2 spurs on locker lines 5 and some warps 3 to core A.Therefore, at the edge of core A, form inside and have the whole soft edge of locker line 5, the outer surface at said edge is only formed by parallel 2 and thinner warp 3.Therefore, the identical surface texture at the edge of seat harness sideband forms, even parallel 2 is only clamped by locker line 5 in a side, because locker line 5 is placed between the thinner warp 3, and covered by parallel 2 towards the surface fully, therefore can not appear at the surface.
Especially, the drag load in the locker line 5 should be selected by this way, makes the latitude pin can locker line 5 and parallel 2 be retracted, and wherein regains or carry the constraint of weaving mode that motion can automatically receive the variation of warp 1 and 3. Warp 1 and 3 weaving mode are the Weaving patterns that is formed by parallel 2, and parallel 2 shuttles back and forth through said warp 1 and 3, and warp 1 and 3 is thus by independently or jointly mobile in groups.Weaving pattern among the core A of existing seat harness sideband is to be formed by two paired warps 1, and two paired warps 1 are alternately passed by parallel 2 at homonymy not respectively.The weaving mode of Weaving pattern among the B of marginal portion and warp thus 3 is formed by alternate group I and III, and said alternate group I and III are formed by three warps 3 respectively or formed by an independent warp 3, and is passed by parallel 2 at homonymy not.Warp 1 between each of parallel 2 is shuttled back and forth and 3 motion are not here described in detail.But, utilize known weaving technology commonly used can understand the motion of said warp 1 and 3 easily.
The weaving mode of being advised of marginal portion B middle longitude 3 helps obtaining the edge, and said thus edge has thickness, and the said thickness basically thickness with the seat harness sideband of core A is identical.
The seat harness sideband of suggestion especially provides following advantage, and said seat harness sideband comprises at least two soft edge much at one, and still, said soft edge can only be weaved with a parallel 2 and a side directed locker line 5.Thus, can obtain the much higher operating rate of safety belt sideband that comprises soft edge than prior art.Loom can make the manufacturing cost of seat harness sideband lack a lot than the seat harness sideband that similarly comprises soft edge with about 1500-1600U/ branch (revolutions per minute) operation.
Another advantage of the present invention is that locker line 5 is no longer distributed to the group of specific warp 1 or 3 as situation of the prior art.Locker line 5 loses its direction and is placed on wittingly between warp 1 and 3; And do not have preset direction, so the seat harness sideband in the fringe region no longer shows the Hardness Distribution that is limited on the lip-deep locker line 5 that appears at the seat harness sideband.
