Side airbag deployment arrangement
View Patent ↗An airbag deployment system for a vehicle is provided. The system can include an airbag positioned between a vehicle frame and a headliner, and a trim member positioned inboard of the frame. The system can also include a deployment ramp coupled to the frame and the trim member. The deployment ramp can have a ramp surface. The ramp surface can be positioned and configured such that when the airbag is deployed a portion of the airbag engages the ramp surface and the trim member to urge the trim member in an outboard direction toward the frame.
1. An airbag deployment system for a vehicle comprising:
an airbag positioned between a vehicle frame and a headliner;
a trim member positioned inboard of the frame;
a deployment ramp coupled to the frame and the trim member, the deployment ramp having a first ramp surface and a second ramp surface, each of the first and second ramp surfaces being integral with and separated by a wall, the wall having a height less than each of the first and second ramp surfaces; and
wherein the ramp surface is positioned and configured such that when the airbag is deployed a portion of the airbag engages the ramp surface and the trim member to urge the trim member in an outboard direction toward the frame.
2. The system of claim 1 , wherein the deployment ramp is formed with the trim member.
3. The system of claim 2 , wherein the trim member further comprises a lower edge portion formed adjacent to the deployment ramp.
4. The system of claim 3 , wherein the lower edge portion has a width between about 2.0 millimeters (mm) and about 10 millimeters (mm).
5. The system of claim 4 , wherein the headliner contacts the lower edge portion and abuts a portion of the deployment ramp.
6. The system of claim 1 , wherein the deployment ramp is positioned and configured so that the airbag deploys along the ramp surface with uninterrupted airbag movement along the ramp surface to urge movement of the trim member in the outboard direction.
7. The system of claim 1 , wherein the trim member is positioned inboard of a C-pillar of the frame.
8. The system of claim 1 , wherein the trim member is positioned inboard of a D-pillar of the frame.
9. An airbag deployment system for a vehicle comprising:
a first engagement member coupleable to a frame of the vehicle such that a portion of the first engagement member is positioned adjacent to a first surface of the frame, the first engagement member having a first rail positioned adjacent to a second surface of the frame to contact an overhead side airbag during deployment, the second surface of the frame opposite the first surface of the frame;
a second engagement member spaced apart from the first engagement member, the second engagement member coupleable to the frame such that a portion of the second engagement member is positioned adjacent to the first surface of the frame, the second engagement member having a second rail positioned adjacent to the second surface of the frame to contact the overhead side airbag during deployment; and
a wall that couples the first engagement member to the second engagement member, the wall having a height less than a height of the first engagement member and a height of the second engagement member, the wall in contact with the second surface of the frame when the first engagement member and second engagement member are coupled to the frame, the wall shaped to contact the overhead side airbag during deployment.
10. The system of claim 9 , wherein the frame includes at least one pillar having the first surface opposite the second surface, a first aperture and a second aperture defined through the first surface and second surface, with the first engagement member coupleable to the first aperture and the second engagement member coupleable to the second aperture so that the portion of the first engagement member and the portion of the second engagement member are positioned adjacent to the first surface of the pillar and the first rail and second rail are positioned adjacent to the second surface of the pillar.
11. The system of claim 10 , wherein the first engagement member, the second engagement member and the wall are integrally formed at an end of a trim member.
12. The system of claim 11 , wherein the first engagement member comprises a first hook and the second engagement member comprises a second hook.
13. The system of claim 12 , wherein the first hook has a width greater than a width of the second hook.
14. The system of claim 12 , wherein each of the first hook and the second hook has a first portion, a second portion and a third portion, the first portion having a first end coupled to the end of the trim member so as to extend outwardly from the trim member at an angle relative to a longitudinal axis of the trim member and a second end coupled to the second portion, the second portion coupled to the first portion and the third portion, the third portion coupled to the second portion at an angle relative to the longitudinal axis of the trim member.
15. An airbag deployment system for a vehicle comprising:
a trim member coupleable to a first surface of a frame of the vehicle and having a deployment arrangement at a first end including:
a first hook coupleable to the frame such that a portion of the first hook is disposed adjacent to a second surface of the frame, the first hook having a first rail positioned adjacent to the first surface of the frame to contact an overhead side airbag during deployment;
a second hook spaced apart from the first hook, the second hook coupleable to the frame such that a portion of the second hook is disposed adjacent to the second surface of the frame, the second hook having a second rail positioned adjacent to the first surface of the frame to contact the overhead side airbag during deployment; and
a wall that couples the first hook to the second hook, the wall having a height less than a height of the first hook and a height of the second hook, the wall positioned adjacent to the first surface of the frame when the first hook and second hook are coupled to the frame, the wall shaped to contact the overhead side airbag during deployment.
16. The system of claim 15 , wherein each of the first hook and the second hook has a first portion, a second portion and a third portion, the first portion having a first end coupled to the end of the trim member so as to extend outwardly from the trim member at an angle relative to a longitudinal axis of the trim member and a second end coupled to the second portion, the second portion coupled to the first portion and the third portion, the third portion coupled to the second portion at an angle relative to the longitudinal axis of the trim member.
17. The system of claim 16 , wherein the third portion of each of the first hook and the second hook is positioned adjacent to the second surface of the frame when the first hook is coupled to a first aperture and the second hook is coupled to a second aperture.
18. The system of claim 17 , wherein the second portion of each of the first hook and the second hook includes a contact surface that contacts the second surface of the frame when the first hook is coupled to the first aperture and the second hook is coupled to the second aperture.
