1. A child safety seat having a seating surface comprising:
- an airbag that is inflatable from a predeployment state to a deployed state;
an activation device for initiating inflation of said airbag; and
an airbag restraint module housing said activation device and said airbag in said predeployment state below said seating surface, and said airbag restraint module having a housing surface that defines an opening through which at least a portion of said airbag is inflatable from said predeployment state to said deployed state in a direction substantially perpendicular to said seating surface;
wherein said child safety seat further comprises an airbag restraint belt positionable to inhibit movement of said airbag in a predetermined direction.

11. A child safety seat having a seating surface, comprising:
-
an airbag that is inflatable from a predeployment state to a deployed state; an activation device including an inertial sensor for initiating inflation of said airbag, said inertial sensor including a weight movable from a first position to a second position and an activation member responsive to movement of said weight for initiating inflation of said airbag; an airbag restraint module housing said activation device and said airbag in said predeployment state below said seating surface, and said airbag restraint module having a housing surface that defines an opening through which at least a portion of said airbag is inflatable from said predeployment state to said deployed state in a direction substantially perpendicular to said seating surface; an airbag restraint belt positionable to inhibit movement of said airbag; and a container filled with compressed gas and having an outlet for said compressed gas that includes a puncturable membrane, said outlet being in communication with said airbag, and wherein said activation member is configured to puncture said membrane in response to movement of said weight.
