Vehicle seat assembly with side-impact airbag deployment mechanism

A vehicle seatback assembly, comprising:

• an outer shell releasably engaged with a seatback carrier via a coupling arrangement to define a mating joint therebetween;
• a seatback frame disposed between the seatback carrier and the outer shell;
• and
• an airbag module coupled to the seatback frame, wherein the coupling arrangement is defined by a pin member releasably coupled to a mounting aperture disposed on the outer shell and releasably coupled to a mounting aperture disposed on the seatback carrier, and further wherein the 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 the mating joint.

A vehicle seatback assembly, comprising:

• an outer shell coupled to a seatback carrier via a releasable coupling arrangement;
• a seatback frame disposed between the seatback carrier and the outer shell;
• and
• an airbag module coupled to the seatback frame, wherein 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 is deployed, wherein the outer shell includes flexibly resilient first and second side members having a plurality of molded-in retention clips disposed thereon, and further wherein the seatback carrier includes first and second side members having a plurality of molded-in retention pins disposed thereon, each molded-in retention pin includes a body portion having a flexibly resilient spring finger received in a mounting aperture defined in the molded-in retention clips in assembly.
