Abstract

A vehicle seatback assembly includes an outer shell coupled to a seatback carrier via a releasable coupling arrangement. The releasable coupling arrangement can take various forms in order to securely couple the outer shell to the seatback carrier. A seatback frame is disposed between the seatback carrier and the outer shell in assembly. An airbag module is coupled to the seatback frame, and the releasable coupling arrangement is configured to release upon deployment of an airbag from the airbag module to define a peripheral gap between the outer shell and seatback carrier through which the airbag can be deployed.

First claim

What is claimed is:

1. A vehicle seatback assembly, comprising:
a rear seatback module defined by an outer shell having first and second side members;
one or more mounting features disposed on one of the first and second side members of the outer shell, wherein each of the one or more mounting features includes first and second mounting fins spaced-apart from one another;
a seatback carrier having first and second side members, wherein the first and second side members of the seatback carrier are configured to align with the first and second side members of the outer shell in assembly;
one or more mounting members disposed on one of the first and second side members of the seatback carrier, wherein the one or more mounting members disposed on the seatback carrier include substantially planar mounting tabs configured to align with the first and second mounting fins disposed on the outer shell in assembly;
a releasable coupling arrangement defined between the one or more mounting features disposed on the outer shell and the one or more mounting members disposed on the seatback carrier;
a seatback frame disposed between the outer shell and the seatback carrier; and
an airbag module coupled to the seatback frame, wherein the releasable coupling arrangement is configured to release upon deployment of the airbag module to disengage a portion of the outer shell from the seatback carrier along a mating joint formed therebetween.

2. The vehicle seatback assembly of claim 1 , wherein the releasable coupling arrangement includes a clip member configured to releasably couple the substantially planar mounting tabs of the seatback carrier to the first and second mounting fins of the outer shell.

3. The vehicle seatback assembly of claim 1 , wherein the airbag module is a side-impact airbag module.

4. The vehicle seatback assembly of claim 1 , wherein the airbag module is substantially concealed by the outer shell.

5. The vehicle seatback assembly of claim 1 , wherein the first and second side members of the outer shell are configured to flex under a force imparted by the deployment of the airbag module to release the releasable coupling arrangement.
