An accessory door panel for a utility vehicle provides a fabric door panel which can be quickly deployed and installed within a utility vehicle for emergency weather use where the utility vehicle has had the factory doors removed at the discretion of the driver. The fabric door panel is fitted to the contours of the door opening and may be stored from an overhead horizontal support member over the door or alternatively stored within a container mounted to the floor at the bottom of the door opening, the door being made of a flexible material that can be stretched across the door opening and anchored at several points along the door frame by independent anchors.

Lift trucks can have an operator compartment designed with an ergonomically improved cab door having a door frame, a set of glass sheets, upper and lower hinges, a handle, a door catch assembly, a door support member, and one or more operator handlebars. The door support member and operator handlebars can be sized and/or positioned to provide structural strength to the door. The cab door can have an unobstructed door design to facilitate maximum operator visibility. The catch assembly can maintain the door in an open position and the operator can readily close the door when desired. In one embodiment, the door includes a vertical operator handlebar and a horizontal operator handlebar that facilitate easy entry into and exit from the operator compartment without unduly obscuring operator visibility through the door.

A collapsible door frame with an extendable fabric cover replaces a factory door for a sport utility vehicle, providing the vehicle for operation without a door while still allowing the drive to assemble and install the collapsible door frame and extend the fabric cover to provide protection from adverse weather conditions.

A door structure of a vehicle includes: an outer panel (4); an inner member (5, 11A) arranged on an inner side of the outer panel in a vehicle width direction; a rigid member (9) arranged between the inner member (5, 11A) and the outer panel (4); and a vibration suppression member (22) arranged between the outer panel (4) and the rigid member (9). The outer panel (4) includes a hem section (10f, 10r, 10u) disposed on a periphery thereof and connected to the inner member (5, 11A) by swaging. The vibration suppression member (22) includes a damping material (22A to 22C) located adjacent to the hem section (10f, 10r, 10u) and being in contact with the outer panel (4) and the rigid member (9).

Class-A components (CAC) include a first and second skin layer each having a polymer matrix and a fiber reinforcing material embedded within the polymer matrix, a third layer disposed between the first and second skin layers and including a third polymer matrix and a filler material interspersed within the third polymer matrix, and a Class-A finish coat applied to the second skin layer. The fiber reinforcing materials include a plurality of substantially aligned carbon fibers and a plurality of low strength regions staggered throughout the carbon fibers. The CAC can be integrated with a rigid vehicle frame. The CAC can be a structural component. The CAC can be a door, a roof panel, or a hood. The CAC can include a layer of woven fibers between the Class-A finish coat and the second skin layer and a portion of the woven fibers can be visible through the Class-A surface layer.

A collapsible door frame with an extendable fabric cover replaces a factory door for a Jeep or other sport utility vehicle, providing the vehicle for operation without a door while still allowing the drive to assemble and install the collapsible door frame and extend the fabric cover to provide protection from adverse weather conditions.

A vehicle includes a vehicle body and a reinforcing patch. The vehicle body component defines a cavity. The reinforcing patch is disposed within and attached to the vehicle body component. The reinforcing patch includes a substrate and a reinforcing body attached to the substrate. The reinforcing body has a first tab, a second tab, and a first slit between the first and second tabs. The slit is at least partially filled by the substrate.

The reinforcement element for reinforcing the structure of a door of a vehicle extends along a main direction and comprises at least a main portion having a reinforcing cross-section (40) extending in a plane substantially perpendicular to the main direction. The reinforcing cross-section (40) includes at least four adjacent branches (42a, 42b, 42c, 42d, 42e, 42f, 42g), each extending in different directions, two successive branches forming a non-zero angle, at least two of the non-zero angles being of opposite signs.
