Abstract
An integral child seat having a back panel which is attached to the seat frame with an extensible, energy absorbing diaphragm. The diaphragm enables the child seat back panel to move forward relative to the seat frame during a vehicle collision to reduce the relative deceleration of a seat occupant's head compared to his/her shoulders, thus reducing the neck loads and neck injuries. As the diaphragm is extended, an enclosed space, defined in part by the diaphragm, increases in size. One or more small orifices are provided to allow a controlled flow of air into this enlarging space. Likewise, after extension, return of the diaphragm to its initial position is controlled by the required expulsion of air from this enlarged space. The orifices restrict the discharge of air from the enlarged space, avoiding a return impact on the seat occupant due to the rebound of the elastic diaphragm.
