  • Patent number: 10730472
    Abstract: An apparatus for helping to protect an occupant of a vehicle comprises an airbag having a primary chamber and a secondary chamber. The primary chamber has a stored condition and is inflatable to a deployed condition to cover a portion of the vehicle. The secondary chamber has a stored condition and is inflatable to a deployed condition to cover portions of the vehicle left uncovered by the primary chamber. At least one passive vent provides fluid communication between the primary and secondary chambers. At least one active vent is actuatable to provide fluid communication between the primary and secondary chambers. An inflator is actuatable to provide inflation fluid to the primary chamber. The at least one passive vent directs inflation fluid from the primary chamber into the secondary chamber. The at least one active vent is actuatable to direct inflation fluid from the primary chamber to the secondary chamber.

  • Patent number: 10710543
    Abstract: A vehicle occupant safety system helps protect front seat occupants of a vehicle in the event of a collision that results in oblique forward occupant movement. The safety system includes a frontal air bag inflatable between on instrument panel end the front seat vehicle occupant, and a central air bag inflatable adjacent and inboard of the frontal air bag. The frontal air bag can be configured and positioned to receive and cushion the vehicle occupant moving in an oblique direction in the vehicle as the result of a vehicle collision. The central air bag can be configured and positioned to support an inboard portion of the frontal airbag against flattening out in response to receiving the obliquely moving occupant, and to engage the obliquely moving occupant's head and resist rotation of the vehicle occupant's head resulting from moving obliquely into engagement with the frontal air bag.

  • Patent number: 10625710
    Abstract: A seat belt retractor comprises (a) a rotatable spool on which seat belt webbing is wound and (b) a load-limiting system to limit a load applied to a vehicle occupant by the webbing. The load-limiting system includes a flow control orifice through which fluid is forced when a load in excess of a predetermined load is applied to the rotatable spool by the webbing. The cross-sectional flow area of the flow control orifice is adjustable in response to unwinding of webbing from the rotatable spool prior to a vehicle crash event and ceases to be adjustable after the crash event is in progress. The load-limiting system also includes a piston in a cylinder. The piston and cylinder are operatively coupled to the spool such that rotation of the spool causes the piston to move relative to the cylinder, which movement causes fluid to be forced through the flow control orifice.

  • Publication number: 20180236965
    Abstract: In a method of folding an airbag (10) for a vehicle occupant restraint system, especially of curtain-type side airbag, to form an airbag package (12?), the airbag (10) is rolled and/or folded to form an airbag roll (12) having a first volume (V1). The airbag roll (12) is fed to a pressing device (14) in which the airbag roil (12) is compressed to form an airbag package (12?) having a second volume (V2) which is smaller than the first volume (V1). The airbag roll (12) and resp., the airbag package (12?) is heated within the pressing device (14) and the airbag package (12?) is cooled, with the airbag package (12?) retaining the second volume (V2) when it is removed from the pressing device (14; 114). The pressing device (14) includes a pressing mold or a molding shaft (18) whose height substantially corresponds to the desired height of the finished airbag packages (12?), a heating unit (20) for heating the airbag packages (12?) and a cooling device (22) for cooling the airbag packages (12?).

  • Patent number: 9637081
    Abstract: A curtain airbag for a motor vehicle includes an inflatable cushion and a protective sheet having an attachment edge attached to the airbag and a free-length extending from the attachment edge. The cushion formed into a folded condition from which it is deployable in a deployment direction, and the free-length of the sheet is positioned adjacent to the deployment direction of the cushion. The airbag is installed in the vehicle to deploy adjacent to a daylight opening of the vehicle. Deployment of the cushion during inflation causes the protective sheet to be drawn along with the cushion in the deployment direction so that the sheet overlays the outboard-facing side of the cushion (between the cushion and the daylight opening) and thereby provides a degree of protection against damage to the cushion that may be caused by, for example, broken window glass.
