Abstract
Description
L'invention concerne un revêtement pour un aménagement intérieur deThe invention relates to a coating for an interior arrangement of
véhicule automobile, pour des zones derrière lesquelles est agencé un coussin gonflable de sécurité (ou airbag). motor vehicle, for areas behind which is arranged an airbag (or airbag).
Des revêtements de ce genre sont connus sous diverses formes de réalisation dans l'état de la technique. Dans les zones derrière lesquelles un coussin gonflable de sécurité est disposé, des amorces de rupture visibles ou invisibles, ce qu'on appelle des lignes de rupture, sont ménagées dans ces revêtements afin que, dans le cas d'un accident, le coussin gonflable de sécurité puisse jaillir hors du tableau de bord, conformément à sa mission, et parer l'impact de l'occupant du véhicule sur le tableau de bord. Dans l'état de la technique, ces amorces de rupture sont pratiquées avec des coupes exécutées à la lame ou au laser. Ce mode de production d'amorces de rupture est relativement compliqué et coûteux parce que, pour assurer une ouverture rapide et précise du coussin gonflable de sécurité en cas d'accident, il faut qu'il soit exécuté avec une grande précision. Coatings of this kind are known in various embodiments in the state of the art. In the areas behind which a safety airbag is disposed, visible or invisible breakout primers, so-called breaklines, are provided in these liners so that, in the event of an accident, the airbag safety can spring out of the dashboard, in accordance with its mission, and counter the impact of the occupant of the vehicle on the dashboard. In the state of the art, these fracture primers are made with cuts made by the blade or the laser. This method of producing breakaway primers is relatively complicated and expensive because, to ensure a quick and accurate opening of the airbag in the event of an accident, it must be executed with great precision.
L'invention a pour but de créer un revêtement pour un aménagement d'intérieur de véhicule automobile dans lequel une amorce de rupture de haute qualité, invisible, est pratiquée dans la zone de la ligne de rupture du coussin gonflable de sécurité d'une façon économique et simple. The object of the invention is to create a coating for a motor vehicle interior arrangement in which a high-quality, invisible, high-quality fracture initiation is practiced in the area of the rupture line of the airbag in a certain manner. economical and simple.
Selon l'invention, le problème est résolu par un revêtement pour un aménagement intérieur de véhicule automobile pour des zones derrière lesquelles un coussin gonflable de sécurité est disposé, remarquable en ce que le revêtement est réalisé sous la forme d'un revêtement textile, en particulier tricoté ou à mailles, et en ce qu'au moins un fil affaibli est incorporé, en particulier entrelacé ou tricoté, dans le revêtement textile, dans la zone d'une ligne de rupture du coussin gonflable de sécurité. According to the invention, the problem is solved by a coating for an interior of a motor vehicle for areas behind which an airbag is arranged, remarkable in that the coating is made in the form of a textile coating, in knitted or knitted fabric, and in that at least one weakened yarn is incorporated, in particular interlaced or knitted, in the textile coating, in the region of a breaking line of the airbag.
Avec l'incorporation d'une amorce de rupture sous la forme d'un fil affaibli dans le revêtement textile, l'amorce de rupture souhaitée est produite déjà au cours du processus de fabrication du revêtement pour l'aménagement d'intérieur de véhicule automobile. Aucun affaiblissement ultérieur de la matière du revêtement pour l'aménagement d'intérieur de véhicule automobile n'est plus nécessaire. Ceci rend possible une fabrication économique d'une amorce de rupture de haute qualité dans le revêtement. With the incorporation of a breaking primer in the form of a weakened yarn in the textile coating, the desired breakout primer is produced already during the process of manufacturing the coating for the interior of a motor vehicle . No further weakening of the coating material for the interior of a motor vehicle is no longer necessary. This makes it possible to economically manufacture a high quality breakthrough in the coating.
Dans une forme avantageuse de réalisation de l'invention, le au moins un fil affaibli est incorporé, en particulier entrelacé ou tricoté, dans le revêtement textile sur le côté éloigné de l'occupant du véhicule. In an advantageous embodiment of the invention, the at least one weakened yarn is incorporated, in particular interlaced or knitted, in the textile coating on the side remote from the occupant of the vehicle.
Un exemple de réalisation de l'invention est représenté sur les dessins et est décrit de façon plus détaillée ci-après. Sur le dessin: la figure 1 montre un tableau de bord de véhicule automobile avec un coussin gonflable de sécurité intégré dans ce tableau et disposé sous un revêtement, la figure 2 montre une coupe de côté, selon la ligne A-A, du tableau de bord 6 représenté sur la figure 1, la figure 3 montre le côté du revêtement textile qui est éloigné de l'occupant. An exemplary embodiment of the invention is shown in the drawings and is described in more detail below. In the drawing: FIG. 1 shows a motor vehicle dashboard with an airbag integrated in this table and placed under a covering, FIG. 2 shows a side cut, along line AA, of the dashboard. As shown in FIG. 1, FIG. 3 shows the side of the textile covering which is remote from the occupant.
La figure 1 montre un tableau de bord de véhicule automobile 6 avec un coussin gonflable de sécurité intégré et disposé sous un revêtement 3. Pour que le coussin gonflable de sécurité sorte rapidement du tableau de bord 6 de la façon voulue en cas d'accident, une arnorce de rupture représentée par une ligne de rupture 5 est ménagée dans le revêtement 3. FIG. 1 shows a motor vehicle dashboard 6 with an integrated safety airbag and placed under a covering 3. In order for the airbag to exit quickly from the dashboard 6 in the appropriate manner in the event of an accident, a fracture bar shown by a break line 5 is formed in the coating 3.
On montre sur la figure 2 une coupe de côté du tableau de bord 6 représenté sur la figure 1, prise selon la ligne A-A. FIG. 2 shows a side section of the dashboard 6 shown in FIG. 1 taken along the line A-A.
On peut remarquer que le tableau de bord 6 présente un logement 1 en forme de cuvette pour le coussin gonflable de sécurité 2. Le coussin gonflable de sécurité 2 est recouvert d'un revêtement textile 3. Le revêtement textile 3 possède un côté 3a dirigé vers l'occupant et un côté 3b qui est éloigné de l'occupant. La ligne de rupture 5 présente dans le revêtement textile 3 est réalisée sous la forme d'un fil affaibli sur le côté 3b du revêtement textile 3 qui est éloigné de l'occupant. Dans le cas d'un accident qui est détecté par un capteur, non représenté ici, le générateur de gaz 4 est activé et le coussin gonflable de sécurité 2 se gonfle, il sort alors du logement 1 en forme de cuvette et, dans ce mouvement, brise l'amorce de rupture constituée par la ligne de rupture 5, pour déployer toute sa dimension et sa fonction devant un occupant du véhicule. It may be noted that the dashboard 6 has a bowl-shaped housing 1 for the airbag 2. The airbag 2 is covered with a textile lining 3. The textile liner 3 has a side 3a directed towards the occupant and a side 3b that is far away from the occupant. The breaking line 5 present in the textile coating 3 is made in the form of a weakened yarn on the side 3b of the textile coating 3 which is remote from the occupant. In the case of an accident that is detected by a sensor, not shown here, the gas generator 4 is activated and the airbag 2 inflates, it then leaves the housing 1 in the form of a bowl and in this movement , breaks the onset of rupture constituted by the breaking line 5 to deploy its full size and its function in front of an occupant of the vehicle.
Le côté 3b du revêtement textile 3 qui est éloigné de l'occupant est représenté sur la figure 3. On peut y remarquer un tissu formé de fils non affaiblis 7 dans lequel au moins un fil affaibli 8 est entrelacé. Le long du fil affaibli 8, est définie une ligne de rupture 5 le long de laquelle le revêtement textile 3 est sectionné par le coussin gonflable de sécurité en cas d'accident. The side 3b of the textile covering 3 which is remote from the occupant is shown in FIG. 3. There can be seen a fabric formed of non-weakened yarns 7 in which at least one weakened yarn 8 is interwoven. Along the weakened wire 8 is defined a break line 5 along which the textile liner 3 is cut by the airbag in the event of an accident.
