Abstract
The disclosure relates to an airbag module that comprises an inflatable airbag, an inflator for inflating the airbag and a plurality of securing units for attaching the airbag module to a vehicle. The airbag has a C-shaped configuration including two juxtaposed legs in an imaginary cross-sectional plane that is transverse to its longitudinal extension. The disclosed design of the airbag is configured to improve deployment behavior such that in a mounting situation of the airbag 10 a central plane defined between the two legs intersects a vertical plane extending through the longitudinal extension of the airbag. A manufacturing method for an airbag module is disclosed.
Claims13
An airbag module comprising:
- an inflatable airbag, wherein, when in a mounted configuration, the inflatable airbag comprises two juxtaposed legs defining a C-shaped configuration in an imaginary cross-sectional plane that extends transversely to a longitudinal extension of the inflatable airbag, and wherein a central plane defined between the two juxtaposed legs intersects a vertical plane extending through the longitudinal extension of the inflatable airbag,
- an inflator for inflating the inflatable airbag,
- a plurality of securing units for attaching the airbag module to a vehicle,
- another portion comprising a first end and a second end, wherein the first end is connected to at least one of the securing units of the plurality of securing units and the second end is connected to at least one of the two juxtaposed legs, wherein the another portion is arranged in a rolled configuration between the first end and the second end;
- wherein the inflatable airbag comprises a first longitudinal portion, a second longitudinal portion, and a third longitudinal portion, wherein an open side of the C-shaped configuration of the first longitudinal portion is oriented towards a first direction, an open side of the C-shaped configuration of the second longitudinal portion is oriented towards a second direction, the second direction different from the first direction, and an open side of the C-shaped configuration of the third longitudinal portion is oriented towards a third direction, the third direction different from the second direction and different from the first direction.

A method of manufacturing an airbag module,
- comprising, rolling and/or folding an inflatable airbag transversely to its longitudinal extension to form an elongate package in which lateral edges of the elongate package are moved toward each other and are fixed so that the inflatable airbag has a C-shaped configuration to form two juxtaposed legs in an imaginary cross-sectional plane transverse to the longitudinal extension of the inflatable airbag, the inflatable airbag comprising a first longitudinal portion, a second longitudinal portion, and a third longitudinal portion, and orientating the inflatable airbag relative to an inflator of the airbag module such that a central plane defined between the two juxtaposed legs intersects a vertical plane extending through the longitudinal extension of the airbag when the inflatable airbag is in a mounted configuration, wherein an open side of the C-shaped configuration of the first longitudinal portion is oriented towards a first direction, an open side of the C-shaped configuration of the second longitudinal portion is oriented towards a second direction, the second direction different from the first direction, and an open side of the C-shaped configuration of the third longitudinal portion is oriented towards a third direction, the third direction different from the second direction and different from the first direction.
An airbag module comprising:
- an inflatable airbag comprising a first longitudinal portion, a second longitudinal portion, and a third longitudinal portion;
- a plurality of securing units for attaching the first longitudinal portion, the second longitudinal portion, and the third longitudinal portion to a vehicle,
- wherein the inflatable airbag includes two juxtaposed legs that form a C-shaped configuration when arranged in a mounted configuration within the vehicle, the two juxtaposed legs connected together by a connecting portion,
- wherein an open side of the C-shaped configuration of the first longitudinal portion is oriented towards a first direction, an open side of the C-shaped configuration of the second longitudinal portion is oriented towards a second direction, the second direction different from the first direction, and an open side of the C-shaped configuration of the third longitudinal portion is oriented towards a third direction, the third direction different from the second direction and different from the first direction.
