Abstract: A vehicle headliner assembly includes a first structural member cooperating with a second structural member to form air ducts between them. A portion of the first structural member is covered by a decorative cover that presents an appearance surface to the vehicle passenger compartment. Integrally formed in the second structural member are an energy absorbing structure and an attachment structure. Thus, the headliner assembly eliminates the need for separate air ducts, separate energy absorbing material, and separate wiring harness and hose clamps. The headliner assembly is also configured to facilitate attachment of passenger compartment devices such as grab handles, without the use of separate fasteners or retainers.

Abstract: A seat support for supporting a vehicle seat outside the vehicle has a base frame adapted for engagement with a support surface outside the vehicle, a support frame configured to engage with and support the vehicle seat, and a plurality of legs connecting the base frame to the support frame. The legs are vertically adjustable in order to vertically adjust the support frame relative to the base frame.
