  • Patent number: 7559572
    Abstract: A safety device for a motor vehicle comprising an inflatable curtain having an upper edge and a lower edge. The upper edge is to be mounted within the interior of a motor vehicle. A first portion of an elongate, flexible element such as a cord extends from a mounting point on the lower edge over a pulley to a sliding ring. A second portion of the cord extends from the mounting point through a guide round a lower pulley through the ring to a lower anchoring point. As the inflatable element inflates so the mounting point on the lower edge moves downwardly, and a triangle of tension is created between the upper pulley, the lower pulley and the mounting point.

  • Patent number: 7556288
    Abstract: A side-impact air bag system for motor vehicles with an air bag (10) extending across at least a part of the longitudinal extent of the vehicle. The air bag (10) is formed by two layers of fabric which are joined to each other and is located in the region of the roof frame of the vehicle in its folded state, before it is unfolded in the form of a curtain. An inflation device (11) releases an inflating gas, and the air bag (10) contains at least one primary chamber (14) which can be inflated by directly feeding gas into it, as well as at least one additional pressure equalization chamber (16), which is separated from the immediately inflatable primary chamber (14).

  • Patent number: 7543849
    Abstract: An inflatable airbag is disclosed which defines an inflatable chamber. The airbag generally includes an inner elastic membrane provided in the peripheral wall of the airbag and a vent-hole formed through the elastic membrane. An outer membrane is provided on the outside of the airbag that extends across at least part of the inner membrane and the vent-hole. The outer membrane defines a pucker over the inner membrane and the vent-hole. The pucker is open so as to define an outlet flow path from the vent-hole when the inner membrane is spaced from the pucker. The inner membrane is configured to stretch and seal against the pucker around the vent-hole when the internal pressure within the inflatable chamber exceeds a predetermined value.

  • Patent number: 7537179
    Abstract: In at least one embodiment of the present invention a seat-belt retractor is provided. The seat-belt retractor comprises a locking system that is controlled by means of at least one vehicle-sensitive sensor. The sensor has an alignment mass for autonomous alignment and is configured to pivot on the seat-belt retractor when the angular installation position of the seat-belt retractor is changed and when the seat-belt is extended, the sensor can be fixed in position by a blocking device. The blocking device is friction-controlled by the rotation of the belt shaft in the extension direction. The blocking device includes a rotatably mounted blocking lever which can be displaced into a release position for the sensor by a control lever that is coupled to the belt shaft by a friction coupling when the belt shaft rotates in a retraction direction.

  • Publication number: 20090096195
    Abstract: To provide an airbag device for a front passenger seat which has a simple construction and can sufficiently absorb an external force applied to an instrument panel. The airbag device for a front passenger seat according to the invention includes: an airbag kept in an inflatable and expandable state; an airbag container which is fixed to a vehicle and accommodates the airbag; and an airbag cover which covers the airbag container. The airbag cover has a cover surface portion on the instrument panel side and a cover extending portion which extends from the cover surface portion in a first direction toward the airbag container. The cover extending portion is characterized by having a deformable region which deforms more easily than the other parts to absorb impact force by deformation. When a pressure (impact force) is applied to the instrument panel from the outside, the deformable region can be deformed elastically or plastically to absorb the impact force.

  • Patent number: 7487997
    Abstract: An air-bag is formed from a single element of laminar material such as fabric. The element defines a rectangular region having linear side edges. This region has a shape and configuration equivalent to that of the air-bag when inflated. Each side edge of the region carries a protruding flap. There are infill elements between adjacent flaps. The flaps are inwardly folded to overlie the rectangular region. Each infill element lies between two respective inwardly folded adjacent flaps. The folded element may be secured to form an air-tight air-bag with reinforced corners.
