A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level. By varying the number and location of the cells the system becomes responsive to the localized pressures exerted on the body for a great variety of users.

A releasable latch (50) is provided for a door assembly (14) having an outer skin member, a foam backing member, and an inner door member. The door assembly conceals an airbag restraint system having a housing, an airbag and a gas generator producing an inflatant for inflating the airbag for deploying the airbag through the door assembly. The releasable latch has a closed U-shaped end that is press fit in an open U-shaped end on a retainer member on the housing to hold the door assembly in a mating relationship to interior trim parts. The inner door member is engaged during initial inflation of the airbag to displace the door assembly so as to bend the inner door member at a hinge joint between the outer cover member and the interior trim part and the press fit between the closed U-shaped end and the open U-shaped end provides easy opening of the door assembly as the airbag is inflated.
