Abstract

The present invention provides for a mounting envelope (1) for receiving a curtain-airbag and for attaching the curtain-airbag to the interior of a vehicle, in particular to the roof frame of a vehicle. The mounting envelope (1) comprises a longitudinal tear-line (3) which is configured to break in the event of a curtain air-bag deployment and extends in a longitudinal direction (L) of the mounting envelope. The mounting envelope is characterized in that it covers at least a major part of a curtain-airbag and in that it comprises at least additional vertical tear-line (7), preferably extending in a direction (V) substantially perpendicular to the longitudinal direction (L).

Claims

1. Mounting envelope (1) for receiving a curtain-airbag and for attaching the curtain-airbag to the interior of a vehicle, the mounting envelope comprising a longitudinal tear-line (3) which is configured to break in the event of a curtain-airbag deployment and extends in a longitudinal direction (L) of the mounting envelope, wherein the mounting envelope covers at least a major part of a curtain-airbag and comprises at least one additional vertical tear-line (7) extending in a direction (V) substantially perpendicular to the longitudinal direction (L), the vertical tear-line (7) comprising alternating cut (23) and non-cut (25) portions.

2. Mounting envelope according to claim 1, wherein the mounting envelope is formed in one piece of fabric.

3. Mounting envelope according to claim 1 wherein the vertical tear-line (7) is arranged in a center portion of the mounting envelope (1) with respect to a longitudinal direction (L) thereof.

4. Mounting envelope according to claim 1, wherein the vertical tear-line (7) spans at least a part of the mounting envelop in a circumferential direction thereof.

5. Mounting envelope according to claim 1, wherein the mounting envelope has a substantially tubular shape.

6. Mounting envelope according to claim 1, wherein at least one of the cut portions (23) of the vertical tear-line (7) crosses at least one of the lateral side edges (27, 29) of the mounting envelope.

7. Mounting envelope according to claim 1 wherein a cut portion (23) of the vertical tear-line (7) crosses the longitudinal tear-line (3) of the mounting envelope.

8. Mounting envelope according to claim 7, wherein the non-cut portions are shorter than the cut portions of the vertical tear-line.

9. Mounting envelope according to claim 1, wherein the mounting envelope is adapted to receive and cover a curtain-airbag which comprises a centrally arranged inflator between a rear part and a front part of the curtain-airbag.

10. Mounting envelope according to claim 1, further comprising one or more openings (5) for providing a view on a curtain-airbag located inside the mounting envelope and for attaching the mounting envelope to a vehicle.

11. Curtain-airbag module comprising a curtain-airbag having a centrally arranged inflator and a mounting envelope (1) according to claim 1.

12. Vehicle at least one curtain-airbag module according to claim 11.

13. Mounting envelope according to claim 1, wherein the mounting envelop attaches the curtain-airbag to a roof frame of the vehicle.

14. Mounting envelope (1) for receiving a curtain-airbag and for attaching the curtain-airbag to the interior of a vehicle, the mounting envelope comprising a longitudinal tear-line (3) which is configured to break in the event of a curtain-airbag deployment and extends in a longitudinal direction (L) of the mounting envelope, wherein the mounting envelope covers at least a major part of a curtain-airbag and comprises at least one additional vertical tear-line (7) extending in a direction (V) substantially perpendicular to the longitudinal direction (L), wherein the vertical tear-line (7) crosses a welding line (13) extending in the longitudinal direction (L) of the mounting envelope.

15. Mounting envelope (1) for receiving a curtain-airbag and for attaching the curtain-airbag to the interior of a vehicle, the mounting envelope comprising a longitudinal tear-line (3) which is configured to break in the event of a curtain-airbag deployment and extends in a longitudinal direction (L) of the mounting envelope, wherein the mounting envelope covers at least a major part of a curtain-airbag and comprises at least one additional vertical tear-line (7) extending in a direction (V) substantially perpendicular to the longitudinal direction (L), wherein the vertical tear-line (7) is substantially aligned with an inflator-position of a curtain-airbag received by the mounting envelope.
