Definitions
- the invention relates to a method for producing a webbing for a safety system of a motor vehicle and a webbing.
- a safety system with a belt strap is used to restrain a vehicle occupant when the motor vehicle is decelerating sharply, so that they decelerate as evenly as possible and contact with objects in the vehicle, for example a steering wheel or a dashboard, is prevented.
- the webbing can also fulfill comfort functions such as a heating function.
- a sensor function can be integrated in the belt strap.
- electrical conductors are usually integrated in the webbing.
- a webbing body is then passed through a calender in the heated state, with the webbing body generally being compressed by 10% to 20%.
- the aim of this process is to smooth the surface of the webbing body and also to reduce or adjust a thickness of the webbing body.
- the problem here is that when the webbing body is compressed in the calender, electrical conductors integrated in the webbing body are heavily loaded, as a result of which the comfort functions can fail after a short service life. It is therefore an object of the present invention to provide a method for producing a webbing and a webbing with an integrated comfort function that has a long service life.
- a method for producing a seat belt for a safety system of a motor vehicle comprising the following steps: a seat belt body is woven, with at least one electrical conductor being woven into the seat belt body, the seat belt body is guided through a calender after heat setting, whereby the webbing body is compressed by a maximum of 5% in the calender.
- the compression refers to the thickness of the belt body before it enters the calender.
- the method according to the invention has the advantage that when the webbing body is passed through the calender, the webbing is smoothed without a high pressure being exerted on the electrical conductors in the webbing body.
- a webbing manufactured in this way has a particularly long service life for the electrically conductive components, without the non-electrical properties of the webbing being adversely altered.
- a webbing body of a webbing manufactured in this way has a higher breaking load than a more strongly compressed webbing body.
- the abrasion resistance of the conductors embedded in the webbing body is improved.
- the electrical conductors of the webbing body produced according to the invention can withstand bending stresses particularly well. Such stresses occur in particular in the area of a tongue through which the webbing is usually guided.
- a webbing body manufactured according to the invention can, for example, withstand more than 50,000 abrasion cycles.
- the webbing body is not compressed in the calender, ie the compression is 0%.
- the process is particularly gentle on the electrical conductors integrated in the body of the belt.
- the belt body is heated before entering the calender. As a result, the webbing body can be smoothed better.
- the webbing body is heated to a temperature of 185°C to 240°C, particularly to a temperature of 190°C to 210°C. An increase to this temperature is necessary in order to set the technical parameters of the webbing, such as stretching.
- the at least one electrical conductor can have a number of individual wires.
- the electrical conductor is particularly flexible. With such an electrical conductor, the method according to the invention avoids the individual wires being pressed against one another too strongly, which can lead to damage to the wires.
- the electrical conductor is, for example, a heating conductor or a sensor, in particular a temperature sensor. This allows comfort functions such as a heating function to be integrated into the seat belt.
- the electrical conductor is preferably woven into the webbing body as a warp thread or as a weft thread. As a result, the electrical conductor can be integrated into the belt webbing body in a particularly simple manner as early as during the production thereof.
- Figure 1 shows schematically a device for producing a webbing according to the invention
- Figure 2 schematically shows a webbing body of a webbing according to the invention
- Figure 3 shows a cross section of an electrical conductor.
- FIG. 1 schematically illustrates a device 10 for producing a webbing 11 for a safety system of a motor vehicle.
- a webbing body 12 is woven in a weaving device that is known per se and not shown in detail here, and then enters a feed device 14.
- the thickness of the webbing body 12 can be influenced by the number of warp threads and the weft thread density. The higher the number of warps and the weft density, the thicker the webbing body 12 and the higher the breaking load of the webbing body 12.
- the weft and warp threads are preferably made of PET.
- the thickness of the webbing body 12 after weaving is between 1 mm and 2 mm, for example.
- a plurality of electrical conductors 16 are woven into the webbing body 12 as illustrated in FIG.
- the electrical conductors 16 are woven into the webbing body 12 as warp threads.
- the electrical conductors 16 can also be woven into the webbing body 12 as weft threads.
- the electrical conductors 16 are heating conductors or sensors.
- FIG. 3 shows a cross section through an exemplary electrical conductor 16.
- the electrical conductor 16 shown has a plurality of individual wires 17.
- other types of electrical conductors 16 are also conceivable.
- the webbing body 12 is dyed in a dyeing machine 18 .
- the dyeing device 18 will not be discussed further at this point, since this method step is sufficiently known from the prior art.
- the webbing body 12 then runs into a fixing device 20, where the webbing body 12 is heated.
- the webbing body 12 is heated to 185°C to 240°C, preferably 190°C to 210°C.
- the webbing body 12 can be stretched or compressed. This adjusts the elongation of the webbing depending on the technical parameters of the yarn used.
- the webbing body 12 then runs through a calender 24.
- the calender 24 comprises two metal rollers 26, 28, between which the webbing body 12 is carried out.
- the belt body 12 is compressed in the calender 24, but according to the invention by a maximum of 5%, based on its thickness before entering the calender 24.
- the belt body 12 is not compressed at all in the calender 24 .
- the webbing body 12 is smoothed without compressing or deforming the electrical conductors 16 in the webbing body 12 .
- the webbing body 12 is usually manufactured as an endless body.
- the webbing body 12 merely has to be cut to length.
