hood

A hood is the collapsible fabric roof assembly fitted to convertible automobiles and carriages. When raised and latched, it forms a weatherproof cover over the passenger compartment; when lowered, it retracts behind the rear seats or into a compartment built into the rear deck. The hood is the convertible's only weather protection, and its operation directly affects the vehicle's usability and resale value.

The frame structure of a hood traditionally uses wooden bows covered in canvas or leather, though modern hoods employ steel or aluminum frames with vinyl or cloth panels. The fabric must resist tearing, water penetration, and UV degradation over thousands of open-and-close cycles. Seams are typically double-stitched or welded, and drainage channels run along the frame to shed water away from occupants. The underside of many hoods is lined with insulation foam to reduce wind noise and heat transfer.

Operation requires a mechanical or electrical actuator to raise and lower the hood smoothly. Manual hoods use handle-and-pulley systems that demand significant physical effort; hydraulic or electric motors ease this burden and are standard on modern convertibles. The locking mechanism must be secure enough to withstand wind pressure at highway speeds without rattling or sagging. A failed latch or torn fabric can make the vehicle unusable until repair.

Wear and failure modes are predictable. The fabric degrades fastest at the seams and folds, where flexing and moisture accumulation accelerate decay. Zips, snaps, or stitching typically fail before the main fabric panel. Hydraulic actuators lose pressure or develop leaks. The rear window (if fitted) clouds or tears. Replacement of a hood is expensive, often requiring removal and reinstallation of the frame and all hardware.

The term derives from the same root as the cover on a carriage or baby's pram, referring to any retractable fabric shelter. In American English, 'hood' denotes the soft convertible roof; in British English, it is sometimes called a 'soft top' or 'roof'. The hood is distinct from the engine cover, which Americans also call a 'hood' and British speakers call a 'bonnet'.
