Abstract: A display apparatus for a vehicle including a vent portion (1) comprising a through-opening defining an air intake mouth, and attachment means adapted to render the vent portion attachable therewith to a surface of the vehicle in a position intimately proximate thereto to permit the air-intake mouth to intake vehicle-displaced airflow at the aforesaid surface of the vehicle. A flexible sleeve portion (35) defines an air duct extending from the through-opening to an air outlet opening of the sleeve portion being inflatable by action of a flow of air therethrough from the through-opening to display an outer surface of the inflated sleeve portion.

Abstract: Headwear (1) including a platform member (9) for use with a headset apparatus (2), the platform member defining an orifice (10A, 10B) therein and shaped to be placed adjacent and to surround an ear of the wearer to expose the ear though the orifice, wherein the platform member has a platform part (9A) moveable relative to another platform part (9B) to releasably hold between the platform parts at least a part of the headset apparatus thereby to detachably attach the headset apparatus to the platform member.

Abstract: A headset apparatus having a headwear member (9) e.g. an ear shell, possessing a surface formation to which a separate attachment device (1) is reciprocally shaped to attach by a push-fit (e.g. by sliding, slotting or clipping) into engagement with the surface formation. In this way the attachment means may be fitted to the surface formation on the headwear member without requiring the use of through-holes passing through the body of the headwear member.
