A vehicle door includes a door box with first and second walls and a second wall and a window frame module, in which a window frame, a first window shaft reinforcement and a second window shaft reinforcement are connected into a structural unit. The first window shaft reinforcement features a groove that accommodates an upper edge of the first wall. An upper edge of the second wall is covered by the second window shaft reinforcement.

Vertical frame portions provided at both side portions of a door frame are a light-metal casting, plural connecting frames, which are a light-meal hollow extrusion molding, connect the vertical frame portions, the vertical frame portions are provided with protrusion portions which engage with inward connecting frames in a longitudinal direction, plural attachment portions which attach the outward connecting frames and the vertical frame portion are provided at different points in the longitudinal direction, and an outward connecting frame is provided with an upper rib which engages with an engagement recess portion provided at an upper portion of a door outer panel formed in a non-planar shape.

A stiffening structure for an automotive door panel part according to the present invention includes a door outer panel 3 made of a metal sheet curved along a height direction, and in which a character line 3a is formed; and an impact beam 5 disposed at an inner surface side of the door outer panel 3. The stiffening structure improves tensile rigidity of the door outer panel 3 by attaching a stiffening member 7 made of resin to the inner surface of the door outer panel 3. The stiffening member 7 includes vertical bone portions 9 extending in a streak shape from the impact beam 5 to the character line 3a along a curve of the door outer panel 3. The vertical bone portions 9 are arranged at a predetermined interval in a front-rear direction of the door outer panel 3, and outer surface of the vertical bone portions 9 is bonded to the inner surface of the door outer panel 3.

A liftgate assembly having finished show surfaces, and process of manufacturing same. The liftgate assembly includes local reinforcements that are overmolded to first reinforcements, and the first reinforcements are infrared welding to a first panel. Second and third reinforcements are also infrared welded to the first panel. To infrared weld the respective reinforcements to the first panel in predetermined locations with respect to the first panel, nesting structures are provided to hold the respective reinforcements and first panel. At least one infrared heating fixture heats various predetermined surfaces on the reinforcements and first panel, and the parts are then pressed together for joining the predetermined surfaces of the respective parts together. The process is repeated, if needed, until all of the reinforcements are infrared welded to the first panel. Outer panels are bonded to the second and third reinforcements.

This disclosure relates to accessories configured to be supported by door strikers of motor vehicles. In particular, the accessories may be mounted to a motor vehicle when a traditional, or factory, door is removed. Some example accessories are useable as a step when mounted to the vehicle, and are also useable as a tool (i.e., as a shovel, flashlight, bit driver, socket wrench, and/or hex wrench) when removed from the vehicle.

A vehicle door assembly with an inner door panel, an outer door panel and a reinforcement assembly. A first attachment area is defined adjacent to an upper edge and a forward edge and a second attachment area is defined adjacent to the upper edge and a rearward edge of the inner door panel. The inner door panel and the outer door panel are fixedly attached to one another and define a hollow space therebetween. The reinforcement assembly has a first end fixedly attached to the first attachment area of the inner door panel and a second end fixedly attached to the second attachment area of the inner door panel. A mid-section extends of the reinforcement assembly extends along the upper edge of the outer door panel. The mid-section of the reinforcement assembly and the upper edge of the inner door panel define a window receiving slot therebetween.

In a vehicle side body structure, when a force that deforms a side door inward in a vehicle width direction acts on the side door, a second engagement section enters a clearance in the vehicle width direction of the side door, a first engagement section and the second engagement section respectively engage with a first engaged section and a second engaged section, and an engagement structure bent with the first engagement section serving as a fulcrum, so as to prevent the side door from flipping up.

Disclosed herein are a vehicle door trim board that is less likely to break due to partial use of an impact resistant resin and a door trim using such a vehicle door trim board. A vehicle door trim board includes a reinforcing part made of an impact resistant resin containing a polyolefin resin, a polyamide resin, and a compatibilizer, wherein the compatibilizer is a modified elastomer having a reactive group that reacts with the polyamide resin. The door trim includes: the vehicle door trim board; and a surface skin layer provided on a design surface side of the vehicle door trim board.
