Disclosed are embodiments of methods and apparatus relating to automotive airbags. In one embodiment of the invention, an airbag cushion is provided having four primary panels. A front panel is provided having a substantially rectangular front face. Two substantially triangular side faces are positioned opposite from one another in the inflated airbag cushion, both of which are connected with the front panel. A rear panel including an upper rear face and a lower rear face is also provided. The upper rear face is connected to a first side of both the first and second side faces and the lower rear face is connected to a second side of both the first and second side faces.

The present invention relates to air bag tethers and to a pattern-wise arrangement of such tethers in relation to air bag panels on a fabric blank, thus resulting in increased fabric utilization per tether and an overall cost savings per finished air bag. The air bag tether system of the present invention is comprised of two congruent tether panels that are joined to one another and to a respective air bag panel. In a preferred embodiment, the tether panel that is attached to the face panel of the air bag is cut in alignment with the warp and the fill of the fabric blank, while the rear tether panel that is attached to the rear panel of the air bag is cut on the bias with respect to the warp and the fill of the fabric blank. The two tether panels are then connected to one another to form a functional tether system. This two-piece construction, with one bias-cut piece, decreases the amount of fabric that is used in the manufacture of the air bag and tethers, while providing sufficient elongation for the tether system to be functional.

An airbag cushion for use in a vehicle restraint system is provided. The airbag cushion is formed from a notched body panel and a rectilinear center panel by a series of substantially straight seams which reduces substantially the elongation of the air bag cushion upon impact on collision of the vehicle in which it is installed. A method of forming the cushion according to the present invention is also provided.

An airbag (1) including two opposing side walls (3) a lower wall (4) and an upper wall (5) forming an inflation opening (2) and a front wall (6). The airbag (1) is formed by sections of a one-part cut fabric (7). The upper wall (5) or the lower wall (4) is formed by two sections (8) of the cut fabric (7) along a connection (9), wherein the cut fabric (7) is folded and only the upper wall (5) or only the lower wall (4) is formed from two sections (8) and from the inflation opening (2) one connection (9) of the one-part cut fabric (7) extends toward the front wall (6). The one-part cut-fabric (7) forms a fitting section (10) for a gas generator. In a flatly extended state the fitting section (1) is adjacent to the two sections (8) forming lower wall (4) or the upper wall (5).

Apparatus (10) for helping to protect an occupant of a vehicle (12) includes an inflatable curtain (14) that is inflatable away from a vehicle roof (18) of the vehicle to a position between a side structure (16) of the vehicle and a vehicle occupant. The inflatable curtain (14) has a length and includes opposite end portions (64 and 66) spaced apart along its length. The inflatable curtain (14) includes a portion that overlies a B pillar (32) of the vehicle (12). The inflatable curtain (14) has a first portion that has a first vertical height and extends from adjacent the B pillar (32) to one of the end portions (64 and 66). The inflatable curtain (14) has a second portion that has a second vertical height and extends from adjacent the B pillar (32) to the other of the end portions (64 and 66). The first and second vertical heights are different from each other.

A head protection airbag according to the invention includes: a shielding main body portion which is manufactured by double weaving, is configured to have a substantially rectangular plate shape when the shielding main body portion is flatly deployed so that a vehicle inside-facing wall and a vehicle outside-facing wall overlap with each other, and covers a window on the inside when the inflation is completed; a plurality of mounting portions which protrude upward from an upper edge of the shielding main body portion and mount the upper edge of the shielding main body portion on an upper edge of the window; and a connection port which has a substantially tubular shape, protrudes upward from the upper edge of the shielding main body portion and allows an inflow of inflation gas into the shielding main body portion. The mounting portions and the connection port are separate from the double-woven shielding main body portion and are connected to the shielding main body portion.

An inflatable vehicle occupant protection device (14) includes a vertically extending central recess (200) and first and second lobes (202 and 204) positioned on opposite sides of the central recess. The central recess (200) and the first and second lobes (202 and 204) are defined at least partially by an elongated center panel (210) of the protection device (14). The center panel (210) includes first and second longitudinal edges (250 and 252) that are spaced apart from each other and that extend along the length of opposite edge portions of the center panel. The center panel (210) also includes first and second end portions (260 and 280) that are spaced apart and that are positioned opposite each other along the length of the center panel. The center panel (210) is arranged in a loop, and a portion (270) of the first longitudinal edge (252) along the first end portion (260) is interconnected with a portion (290) of the second longitudinal edge (250) along the second end portion (280) of the panel to form a vertically extending seam (220) that helps define the central recess.
摘要:
Inflatable devices such as airbags are detailed. The bags may be formed of components well nested on linear rolls of material, reducing material wastage. The airbags additionally may, in some cases, be formed of components lacking curved surfaces; in certain cases the bag components additionally may have complementary surfaces that, although formed of straight segments, resemble convex and concave shapes.
