Abstract

A safety airbag assembly having a safety airbag comprising a bag, and an elastic connection member for connecting the safety airbag to a body frame of a vehicle, wherein the bag is provided with a protruding sheet connected to the elastic connection member, the elastic connection member is configured to be in a curvilinear shape formed by connecting a plurality of sections end to end, and the plurality of sections of the elastic connection member comprise hook-like first ends, hook-like second ends, and middle portions located between the first ends and the second ends, with the middle portions being con-figured to be connected to the protruding sheet of the bag, and the first ends and the second ends being configured to suspend the bag connected to the middle portions on the body frame.

First claim

The invention claimed is:

1. A safety airbag assembly for a vehicle having a vehicle body frame, the safety airbag assembly comprising:
an airbag; and
an elastic connecting member used to connect the airbag to the vehicle body frame,
wherein the airbag is provided with a lug for connection to the elastic connecting member,
wherein the elastic connecting member is configured to be in the shape of a curved line formed by connecting a plurality of sections end to end in sequence, and the plurality of sections of the elastic connecting member comprise a hook-shaped first end, a hook-shaped second end, and an intermediate portion located between the first end and the second end,
wherein the intermediate portion is configured to be connected to the lug of the airbag such that an end of the lug goes around the intermediate portion and is fixed to the lug, and
wherein the first end and the second end are crossed to each other and are configured to suspend the airbag connected to the intermediate portion of the elastic connecting member connected to the vehicle body frame.

2. The safety airbag assembly according to claim 1 , wherein the plurality of sections of the elastic connecting member are formed by bending a single wire material.

3. The safety airbag assembly according to claim 2 , wherein the airbag is used as an airbag curtain.

4. The safety airbag assembly according to claim 3 , wherein the lug is further provided with a bolt and nut assembly for connection to the vehicle body frame.

5. A safety airbag assembly for a vehicle having a vehicle body frame, the safety airbag assembly comprising:
an airbag; and
an elastic connecting member used to connect the airbag to the vehicle body frame,
wherein the airbag is provided with a lug for connecting to the elastic connecting member,
wherein the elastic connecting member includes a hook-shaped first end, a hook-shaped second end, and an intermediate portion located between the first end and the second end,
wherein the intermediate portion is configured to be connected to the lug of the airbag,
wherein the first end and the second end are configured to suspend the airbag connected to the intermediate portion from the vehicle body frame,
wherein the lug is provided with a material void portion provided with a first group of positioning points A, B, C, and D, and the intermediate portion is provided with a second group of positioning points A′, B′, C′, and D′,
wherein when the intermediate portion is configured to be connected to the lug, the first group of positioning points correspond to the second group of positioning points in a one-to-one manner, and
wherein the intermediate portion uses the second group of positioning points as demarcation points respectively and extends from a first side of the lug to a second side of the lug opposite the first side so as to prevent the lug from moving upwards, downwards, leftwards, or rightwards relative to the elastic connecting member.

6. The safety airbag assembly according to claim 5 , wherein the material void portion is provided with holes at positions of the first group of positioning points respectively.

7. The safety airbag assembly according to claim 5 , wherein the material void portion comprises an opening, the first group of positioning points are provided at the opening, and when the intermediate portion extends from the first side of the lug to the second side of the lug at the second group of positioning points respectively, the intermediate portion extends to be wider and/or higher than the opening on the first side or the second side of the lug.

8. The safety airbag assembly according to claim 7 , wherein the opening is configured to be a rectangular opening.

9. The safety airbag assembly according to claim 7 , wherein the opening is configured to be two elongated openings; the first group of positioning points are respectively provided at respective end points of the elongated openings, and when the intermediate portion extends from the first side of the lug to the second side of the lug at the second group of positioning points respectively, the intermediate portion extends to be wider than the elongated openings on the first side or the second side of the lug.

10. The safety airbag assembly according to claim 9 , wherein the plurality of sections of the elastic connecting member are formed by bending a single wire material.

11. The safety airbag assembly according to claim 7 , wherein the plurality of sections of the elastic connecting member are formed by bending a single wire material.

12. The safety airbag assembly according to claim 5 , wherein the plurality of sections of the elastic connecting member are formed by bending a single wire material.
