Description

Method for weaving seat belt webbing and seat belt webbing Technical Field The present invention relates to a safety device for a vehicle, and in particular, to a webbing weaving method and webbing. Background A seat belt for a motor vehicle comprises a webbing, and the webbing is usually formed from a fabric via weaving. In the event of a rapid deceleration of the vehicle and a corresponding force acting on the vehicle occupant, the seat belt serves to fix the vehicle occupant to the vehicle seat. The seat belt is part of a safety device that includes a pretensioner that can tension the webbing in the event of an impending collision or the like. This ensures that the vehicle occupant can be secured to the vehicle seat via the seat belt, for example, in the initial stage of a crash. The webbing is in contact with the body of a passenger seated in the seat. In order to meet the heating requirement of passengers, the webbing can be provided with a heating element, or in order to facilitate the passengers wearing the safety belt in a dark environment, the webbing can be provided with a lighting element. For this purpose, the heating element or the lighting element is usually woven in the webbing. Braiding heating or lighting elements in a webbing belt makes it difficult to flexibly design the location of the heating or lighting elements on the webbing belt. It is therefore desirable to provide a seat belt webbing that is capable of placing functional elements in a flexible manner. Disclosure of Invention The object of the present invention is to provide a webbing weaving method and webbing that can place a functional member in a flexible manner. An aspect of the present invention provides a method of weaving a webbing for a seat belt, comprising the steps of: providing a first knitting line, a second knitting line and a third knitting line, Extending the first webbing in a first direction, extending the second webbing in a second direction different from the first direction, and weaving the first webbing and the second webbing to form a first layer and a second layer of a seat belt webbing, The third wire is woven onto one of the first layer and the second layer at a separate section of the first layer and the second layer, and a first section of the third wire is positioned between the first layer and the second layer, a second section of the third wire protruding a predetermined distance from an outer surface of the seat belt webbing. According to an embodiment of the invention, further comprising providing a fourth thread, extending the fourth thread from the outer side through the inner side in only one of the first layer and the second layer at the separation section, and then returning the outer side again to separate the first layer and the second layer from each other; At the connection section of the first and second layers, the fourth weave is extended from the outer side of the first layer through the inner side of both the first and second layers, the outer side of the second layer, and then returned again to the outer side of the first layer to connect the first and second layers to each other. According to an embodiment of the invention, the separation sections and the connection sections are alternately arranged in the width direction of the webbing. According to an embodiment of the invention, the first direction is defined as a length direction of the seat belt webbing and the second direction is defined as a width direction of the seat belt webbing. According to an embodiment of the invention, both the third and fourth threads extend along the first direction. According to an embodiment of the invention, it is further comprised to provide a functional element which is fixed at the first or second section of the third wire, after which a force is applied at the second or first section of the third wire and the third wire is withdrawn from the seat belt webbing such that the functional element is positioned between the first and second layers. Another aspect of the invention provides a seat belt webbing, Wherein, the The seat belt webbing is manufactured according to the aforementioned seat belt webbing weaving method and comprises a cavity defined by the first layer and the second layer at the separation section, in which cavity a functional element is provided. According to an embodiment of the invention, at the separation section, a fourth thread extends from the outer side through the inner side in only one of the first layer and the second layer and then back to the outer side again; at the connecting section of the first and second layers, the fourth weave line extends from the outer side of the first layer through the inner side of both the first and second layers, the outer side of the second layer, and then back to the outer side of the first layer again.
