Definitions

  • Inflatable protective cushions used in passenger vehicles are a component of relatively complex passive restraint systems.
  • the main elements of these systems are: an impact sensing system, an ignition system, a propellant material, an attachment device, a system enclosure, and an inflatable protective cushion.
  • the propellant Upon sensing an impact, the propellant is ignited causing an explosive release of gases filing the cushion to a deployed state which can absorb the impact of the forward movement of a body and dissipate its energy by means of rapid venting of the gas.
  • the entire sequence of events occurs within about 30 milliseconds.
  • the cushion In the undeployed state, the cushion is stored in or near the steering column, the dashboard, in a door, or in the back of a front seat placing the cushion in close proximity to the person or object it is to protect.
  • the permeability of the cushion structure is an important factor in determining the rate of inflation and subsequent rapid deflation following the impact event.
  • the use of several fabric panels in construction of the cushion may prove to be a useful design feature .
  • FIG. 1 there is shown an unfolded and unseamed inflatable restraint cushion (airbag) 2.
  • this unfolded and unseamed inflatable restraint cushion 2 includes a first body panel section 10 and a second body panel section 12 which are mirror images of each other.
  • these body panel sections 10, 12 are not required to be of the same shape and configuration. However, it has proven more cost effective to cut the body panel sections 10, 12 as two separate pieces and attaching them to each other through the use of a substantially straight seam.
  • the body panel sections 10, 12 (or the larger panel section in the alternative embodiments) are altered to fit the entire width of the fabric in order to provide the most efficient use of the fabric itself.
  • Attached to the end of these body panel sections 10, 12 are two end panels 14, 16, which are also mirror images of each other. As with the body panel sections 10, 12, these end panels 14, 16 may be of any configuration or shape in alternative embodiments. Furthermore, the end panels 14, 16 may also be omitted in order for a one-piece airbag (such as in FIG. 6) to be utilized. Separating the two body panel sections 10, 12 is a rectilinear separator panel section 18.
  • airbag 2 has been illustrated and is described herein in terms of the principal panel sections 10, 12, 18, it is to be understood that such airbag 2 may also include additional components such as shape defining tethers, gas vents, and the like as may be known to those in the skill of the art. While specific embodiments of the invention have been illustrated and described, it is to be understood that the invention is not limited thereto, since modifications may certainly be made and other embodiments of the principals of this invention will no doubt occur to those skilled in the art. Therefore, it is contemplated by the appended claims to cover any such modifications and other embodiments as incorporate the features of this invention which in the true spirit and scope of the claims hereto.

Abstract

La présente invention concerne un système de retenue pour véhicule (4) comportant un coussin d'air (6)dans lequel peut être logé un ensemble de cartouche de gonflage (44, 46). Le coussin d'air (6) comprend de préférence deux éléments plats (30, 32) reliés l'un à l'autre par un joint (34) essentiellement droit, un panneau intercalaire (40) qui, lors du pliage et de l'arrimage des deux éléments plats (30, 32) du coussin d'air (6), forme une poche (42) dans laquelle vient se loger la cartouche de gonflage (44, 46) susmentionnée. Un tel article se gonfle rapidement et complètement au moment où l'agent propulseur est libéré et se range facilement dans une enveloppe classique pour système de retenue. L'invention concerne à la fois le système de retenue (4) et le coussin gonflable (6) proprement dit.
