Abstract
A method of packaging an air-bag includes providing an air-bag having a base. A first part of the air-bag is folded at least partly towards the base of the air-bag and additionally folded such that the first part of the air-bag incorporates at least one Z-fold. The first part of the air-bag and a second part of the air-bag are at least partly rolled towards the base of the air-bag to package the air-bag.
Claims25
A method of packaging an air-bag, the method comprising:
- providing an air-bag having a base, the base having a base axis extending along a longitudinal length thereof;
- folding a first part of the air-bag at least partly towards the base of the air-bag and additionally folding the first part of the air-bag such that the first part of the air-bag defines at least one Z-fold;
- and
- rolling the folded first part of the air-bag and a second part of the air-bag at least partly towards the base of the air-bag to package the air-bag, wherein the Z-fold extends along a line oblique to the base axis,
- wherein the base of the air-bag includes an inlet extending along an inlet access for connecting to a source of gas;
- the inlet access being oblique to the line along which the Z-fold extends.
A packaged air-bag for use in a vehicle, the air-bag comprising:
- a base which incorporates an inlet, the base having a base axis extending along a longitudinal length thereof;
- a first part of the air-bag being folded towards the base of the air-bag and additionally folded to define at least one Z-fold, the first part of the air-bag and a second part of the air-bag being at least partly rolled, wherein gas introduced into the air-bag through the inlet exerts a force which at least partly unrolls the air-bag and then subsequently at least partly unfolds the air-bag,
- wherein the at least one Z-fold extends along a line oblique to the base axis.
A method of packaging an air-bag, the method comprising:
- providing an air-bag having a base,
- folding a first part of the air-bag at least partly towards the base of the air-bag and additionally folding the first part of the air-bag such that the first part of the air-bag defines at least a first Z-fold;
- rolling the folded first part of the air-bag and a second part of the air-bag at least partly towards the base of the air-bag to package the air-bag;
- and
- folding the second part of the air-bag such that the second part of the air-bag defines at least a second Z-fold.
A method of packaging an air-bag, the method comprising:
- providing an air-bag having a base, the base having a base axis extending along a longitudinal length thereof;
- folding a first part of the air-bag at least partly towards the base of the air-bag and additionally folding the first part of the air-bag such that the first part of the air-bag defines at least one Z-fold;
- and
- rolling the folded first part of the air-bag and a second part of the air-bag at least partly towards the base of the air-bag to package the air-bag, wherein the Z-fold extends along a line oblique to the base axis,
- wherein the air-bag is a pedestrian-protecting air-bag having a central portion having a first height measured from a lower end of the base and first and second lateral sides each having a second height greater than the first height.
