Abstract
A shock-absorbing device for vehicles includes a supporting bar, and a gas generator and an airbag arranged on the supporting bar. The airbag includes an inflatable body with a first laminated foil wrapped longitudinally around the inflatable body and a second laminated foil wrapped transversely around the inflatable body. The first and second laminated foils are initially wrapped around the inflatable body in a temporary inflated state of the inflatable body so as to have a length in the respective longitudinal and transverse directions corresponding to the inflatable body in an activated state of the shock-absorbing device.
Claims15
A shock-absorbing device for vehicles, comprising:
- a supporting bar;
- one or more gas generators arranged on the supporting bar;
- an airbag arranged on the supporting bar;
- the airbag further comprising an inflatable body with a first laminated foil wrapped longitudinally around the inflatable body and a second laminated foil wrapped transversely around the inflatable body;
- wherein the first and second laminated foils are initially wrapped around the inflatable body in a temporary inflated state of the inflatable body;
- the first and second laminated foils wrapped around the inflatable body in an activated state of the shock-absorbing device and comprising a length that limits a volume of the inflatable body in the activated state of the shock-absorbing device;
- and
- wherein the first laminated foil is wrapped on the inflatable body in a direction perpendicular to a length direction of the supporting bar, and the second laminated foil is wrapped on the inflatable body over the first laminated foil in a direction perpendicular to the first laminated foil.
