Definitions

  • the airbag cushion is formed on the whole and securely fixed to provide strong firmness at the side portion, thereby restricting the movement of occupants. Accordingly, the collision between occupants can be prevented upon vehicle collision.
  • the middle side airbag is typically inflated between the driver seat and the passenger seat. Especially, as shown in FIG. 1, the middle side airbag is deployed from a lateral surface of an arm rest 5 of a console box as shown in FIG. 1.
  • the middle side airbag when the middle side airbag is inflated upon the side collision of the vehicle, the middle side airbag is not stuck, so that the driver 1 and the passenger may collide with each other beyond of the airbag.
  • the middle side airbag according to the related art may have only the size enough to protect the head of an occupant from impact, the whole size of the middle side airbag is increased because the middle side airbag must have the operating relation of forming a partition on the whole. Accordingly, the injection volume of air is increased, so that the inflation speed of the airbag may be decreased. In addition, since the middle side airbag must form a thin and wide partition, the middle side airbag may be not inflated (deployed) completely. Accordingly, the operating failure of the middle side airbag may occur.
  • Another object of the present invention is to provide a middle side airbag stuck by frictional pressure, in which an airbag cushion is inflated with a height enough to make contact with the surfaces of both of a vehicle roof and a mid-tower console, so that the airbag cushion is supported by the frictional pressure at the vehicle roof and the mid-tower console to form a partition, thereby providing strong firmness at the side portion.
  • Still yet another object of the present invention is to provide a middle side airbag, in which the deployment time of the airbag cushion and the package of the airbag module can be optimized when the airbag module is installed at the central portion of the mid-tower console, so that the airbag module is mounted (inflated) in a region in which friction is caused by the mid-tower console, thereby optimizing the performance of the middle side airbag module and the size of the airbag module.
  • a middle side airbag inflated between a passenger and a driver to prevent the passenger and the driver from being injured due to side collision therebetween.
  • An inflator is placed in a mid-tower console to inject air into the middle side airbag.
  • the middle side airbag includes a vehicle-roof-side cushion contact part provided at an upper portion of the middle side airbag to make contact with a vehicle roof, and a mid-tower-console-side cushion contact part provided at a lower rear surface of the middle side airbag to make contact with a mid-tower console.
  • FIG. 4 is a front view showing the deployment of the middle side airbag according to the present invention.
  • FIGS. 5 and 6 are a mid-tower-console-side cushion contact part having a plurality of stitch lines according to another embodiment of the present invention.
  • the middle side airbag 100 is inflated between the passengers seated on rear seats of the vehicle and between the driver 1 and the passenger seated on front seats of the vehicle to prevent the passengers and the driver from being injured due to the side collision therebetween.
  • An upper portion of the middle side airbag 100 makes contact with a vehicle roof 110 and a lower lateral surface thereof is pressurized and supported by the mid-tower console 153.
  • the middle side airbag 100 can be inflated in the vertical direction with a height enough to act as a partition.
  • the present invention provides the middle side airbag 100 inflated between the driver 1 and the passenger to prevent passengers seated on rear seats of the vehicle or the driver 1 and the passenger seated on front seats of the vehicle from being injured due to the side collision therebetween.
  • the inflator 120 to inject air into the middle side airbag 100 is placed in the mid-tower console 153, and the middle side airbag 100 is provided at the upper portion thereof with a vehicle-roof-side cushion contact part 165 making contact with the vehicle roof 110 and at a lower rear surface thereof with a mid-tower-console-side cushion contact part 163 making contact with the mid-tower console 153.
  • the middle side airbag 100 is inflated in the vertical direction to form a partition, at a region in which the heads of the driver 1 and the passenger collide with each other upon the vehicle collision, without making contact with the lower portion of the arm rest 150 that does not support the middle side airbag 100. Accordingly, the whole size of an airbag module can be reduced by reducing the size of an airbag cushion, so that the material cost for the middle side airbag 100 can be reduced. Accordingly, the middle side airbag 100 has an advantage in terms of economic feasibility.
  • the upper portion of the middle side airbag 100 makes contact with the vehicle roof 110 and the lower portion of the middle side airbag 100 makes contact with a front surface of the mid-tower console 153, so that the upper and lower portions of the middle side airbag 100 have contact surfaces strongly pressurized by the internal air pressure of the air cushion. Accordingly, the middle side airbag 100 may be securely stuck by frictional support force in the vertical and inclination directions.
  • the middle side airbag 100 is strongly pressurized at the vehicle-roof-side cushion contact part 165 between the upper portion of the middle side airbag 100 and the vehicle roof 100 due to the strong internal air pressure of the airbag cushion, so that great frictional support force occurs between the surfaces of the upper portion of the middle side airbag 100 and the vehicle roof 100.
  • great frictional support force occurs in the lower portion of the middle side airbag 100, that is, the mid-tower-console-side cushion contact part 163 between the lower inner lateral surface of the airbag cushion and the lateral surface of the mid-tower console 153.
  • the frictional resistance R may have various values according to the frictional coefficient of the material of each surface. Accordingly, in order to increase the frictional resistance R, each surface is preferably made of a material representing great frictional coefficient.
  • the middle side airbag 100 is preferably made of a material allowing the middle side airbag 100 to have a rough surface.
  • the vehicle roof 110 may be made of soft fabric representing great frictional coefficient.
  • the middle side airbag 100 pressurized and supported by frictional resistance R is fixedly pressurized at the upper and lower portions thereof so that the middle side airbag 100 is securely fixed on the whole. Accordingly, the middle side airbag 100 sufficiently acts as a partition at the side of the head of the driver 1. Therefore, according to the present invention, the airbag cushion is inflated with a height enough to simultaneously make contact with the surfaces of the vehicle roof 110 and the mid-tower console 153. Accordingly, the inflated airbag cushion can be supported by frictional pressure at the sides of the vehicle roof 110 and the mid-tower console 153 to act as a partition, and have strong lateral surface firmness.
  • the middle side airbag 100 is deployed upon the side collision of the vehicle to form a partition, so that the collision impact between passengers seated on the rear seats of the vehicle may be absorbed.
  • the driver and the passenger seated on the front seats of the vehicle are confined at left and right sides, thereby preventing the driver and the passenger having a passenger seat from being injured when the driver collides with the passenger having the passenger seat.
  • the middle side airbag 100 can securely prevent the driver from being inclined toward the passenger seat due to the impact caused by the side collision of the vehicle.
  • the upper portion of the middle side airbag 100 having the above structure according to the present invention can be supported by pressure support force occurring together with the vehicle roof 110, and the lower portion of the middle side airbag 100 may form a vertical partition with pressure support force greater than pressure support force occurring by the horizontal arm rest 152.
  • the middle side airbag 100 includes the mid-tower-console-side cushion contact part 163 and the vehicle-roof-side cushion contact part 165 which are provided at the sides of the vehicle roof 110 and the mid-tower console 153, respectively, pressurized by internal air of the middle side airbag 100 when the airbag 100 is inflated, and pressure-supported by frictional resistance R, so that the middle side airbag 100 can form a firm partition.
  • the support through the pressure can be firmly achieved by the pressure F of air discharged from the inflator 120 of the airbag module, air pressure P1 applied to the vehicle roof 110, and air pressure P2 applied to the front surface of the mid-tower console 153, so that the middle side airbag 100 can sufficiently act as a partition.
  • the middle side airbag 100 can effectively ensure the safety of the occupants.
  • the deployment time of the airbag cushion and the package of the airbag module can be optimized when the airbag module is installed at the central portion of the front surface of the mid-tower console. Accordingly, the airbag module is mounted (inflated) upward from the mid-tower-console-side cushion contact part 163, so that the performance of the middle side airbag module and the size of the airbag module can be optimized. Accordingly, the middle side airbag can perform a stable airbag function.

Abstract

L'invention concerne un airbag central maintenu par une pression de frottement. L'airbag central permet d'empêcher que des passagers assis sur les sièges arrière et un conducteur et un passager assis sur les sièges avant ne soient blessés lors de la collision latérale d'un véhicule ou permet de limiter le mouvement du conducteur en direction du siège du passager en raison de la collision latérale du véhicule même si le conducteur est seul dans le véhicule. Un coussin d'airbag est gonflé de manière à présenter une hauteur suffisante pour entrer en contact avec les surfaces d'un toit de véhicule et d'une console de type tour centrale de sorte que le coussin d'airbag soit supporté par la pression de frottement au niveau du toit du véhicule et de la console de type tour centrale afin de fournir une grande fermeté au niveau de la partie latérale. L'airbag central comprend des lignes de couture qui sont déchirées lorsque la pression interne du coussin d'airbag est modifiée par la collision entre un conducteur et un passager.
