Side airbag for a motor vehicle
View Patent ↗A side airbag is provided for a motor vehicle, in particular a passenger automobile, having an airbag and tensioner for stretching out the unfolded airbag. The tensioner has a peripheral, fillable tensioning frame.
1. A side airbag for a motor vehicle, comprising:
an airbag;
a tensioner adapted to stretch-out the airbag in an unfolded configuration; and
a peripheral and fillable tensioning frame adapted for the tensioner, wherein the tensioning frame comprises a first elasticity and the airbag has a second elasticity that is less than the first elasticity.
2. The side airbag according to claim 1 , wherein the tensioning frame expands in a radial direction upon filling and shortens in an axial direction between a plurality of fastening points that are spaced apart in a vehicle longitudinal direction in order to stretch out the airbag.
3. The side airbag according to claim 1 , wherein the tensioning frame is fastened to an outer edge of the airbag.
4. The side airbag according to claim 1 , wherein the tensioning frame comprises a first transverse contraction and the airbag has a second transverse contraction that is less than the first transverse contraction.
5. The side airbag according to claim 1 , wherein the tensioning frame is implemented with a plurality of parts and comprises a filling hose and a casing that encloses the filling hose.
6. The side airbag according to claim 5 , wherein the casing is produced as at least a single-layer from a plurality of fine filaments.
7. The side airbag according to claim 5 , wherein the casing is implemented as a net-like casing.
8. The side airbag according to claim 5 , further comprising a constriction link that comprises a ring, a tuck, and/or a woven constriction.
9. The side airbag according to claim 8 , wherein the tensioning frame comprises a plurality of multiple constriction links with a spacing ratio that differ from one another.
10. The side airbag according to claim 8 , wherein the tensioning frame comprises a plurality of multiple constriction links with a diameter ratio that differ from one another.
11. The side airbag according to claim 5 , further comprising a constriction link that comprises a ring.
12. The side airbag according to claim 5 , further comprising a constriction link that comprises a tuck.
13. The side airbag according to claim 5 , further comprising a constriction link that comprises a woven constriction.
14. The side airbag according to claim 1 , wherein an upper area of the tensioning frame, in a filled state, is situated in an area of a roof-side vehicle body structure.
15. The side airbag according to claim 14 , further comprising an additional fillable protective chamber that is situated in a lateral roof area in the filled state.
16. A side airbag module, comprising:
a gas generator;
a side airbag comprising:
a tensioner adapted to stretch-out the side airbag in an unfolded configuration; and
a peripheral and fillable tensioning frame adapted for the tensioner, wherein the tensioning frame comprises a first elasticity and the airbag has a second elasticity that is less than the first elasticity; and
a filling tube adapted to fill the tensioning frame of the side airbag through the gas generator.
17. The side airbag module according to claim 16 , further comprising a second filling tube adapted to fill the tensioning frame of the side airbag through the gas generator.
18. A side airbag for a motor vehicle, comprising:
an airbag;
a tensioner adapted to stretch-out the airbag in an unfolded configuration; and
a peripheral and fillable tensioning frame adapted for the tensioner, wherein the tensioning frame is fastened to the airbag along an entire outer edge thereof.
