A vehicle tailgate is made of a plastic material and includes: an inner panel, an outer panel and a first glue bead applied between the inner panel and the outer panel, such that the inner panel and the outer panel are assembled via the glue bead and an inner space is disposed between the inner panel and the outer panel. The outer panel includes: a skin with an appearance surface; a housing configured to receive an optical unit, delimited by a peripheral wall joined to the skin; and a cavity delimited by the skin, at least a portion of the peripheral wall of the housing, and walls projecting from the housing towards an inner face of the skin. At least one of the walls projecting from the housing towards the inner face of the skin does not touch the inner face of the skin, such that there is a gap between the at least one wall and the inner face of the skin. The gap is sealed by a second glue bead.

A lightweight and simplified vehicle door assembly is provided with four main components, an upper frame positioned about the window, an inner frame structure, an outer body panel, and a composite reinforcement component. The composite reinforcement component provides an all-in-one solution for a side impact cross beam, as well as an upper door reinforcement, a front door pillar reinforcement, and a rear door pillar reinforcement. The composite reinforcement component acts to reinforce the overall door structure, offers resistance to a side impact that limits the intrusion into the passenger compartment, and offers resistance to a frontal impact by maintaining the spacing between the vehicle A and B pillars (for a front door) and pillar C and D for a back door. A coupe vehicle door in which there is no window frame may be reinforced with the composite reinforcement component. The composite reinforcement component may have continuous or chopped fibers.

A window regulator including a panel and a guide rail. The panel may define a speaker aperture that may be configured to receive at least a portion of the speaker. The guide rail may be integrally formed to the panel and configured to carry a slider. The slider may be configured to move along the guide rail to move the window between a first position and a second position. The guide rail may include an aperture-region portion that may extend across the speaker aperture in a first direction. The aperture-region portion may include a first sidewall and a second sidewall that may each extend in a second direction that may be substantially orthogonal to the first direction.

Disclosed is a high-integration-level plastic tail door, comprising a tail door upper outer plate, a tail light, a tail door lower outer plate, an inner plate, and a high brake light, wherein the tail door upper outer plate, as a whole, is integrated with a spoiler, a tail door windshield, a windscreen decorating member, and a high brake light cover; the tail door upper outer plate is of two layers and is formed by means of double-shot molding, with a first layer being a transparent layer and a second layer being a black non-transparent layer; a first open hole is provided at the position of the high brake light in a black non-transparent layer area; a second open hole is provided in the middle of the tail door windshield; and a hardened coating is arranged on the outer layer of the transparent layer.

There are provided an outer member, an inner member including a front-side vertical wall portion and a rear-side vertical wall portion, an impact bar extending from front-side attachment portions of the front-side vertical wall portion to rear-side attachment portions of the rear-side vertical wall portion, a hinge-reinforcement member reinforcing a hinge attachment portion where a hinge is attached to the front-side vertical wall portion, and a latch-reinforcement member reinforcing a latch-attachment portion where a latch device is attached to the rear-side vertical wall portion. The front-side vertical wall portion and the rear-side vertical wall portion are made of casting or high-strength resin, and the hinge-reinforcement member and the latch-reinforcement member are configured to have higher ductility than the front-side vertical wall portion and the rear-side vertical wall portion and connected to the impact bar.

A polyolefin resin composition, containing: a polyolefin resin; and cellulose microfibrils, in which a content of the cellulose microfibrils is 0.5 to 20 parts by mass, with respect to 100 parts by mass of an entire resin component in the polyolefin resin composition, a molded article and a back door for a vehicle.

The present disclosure provides a composite lift gate for a vehicle. The composite lift gate includes a polymer matrix and a fiber assembly. The fiber assembly is embedded in the polymer matrix. The fiber assembly includes a fiber mat and a plurality of substantially-aligned continuous fibers. The plurality of substantially-aligned continuous fibers is directly connected to a portion of the fiber mat. In one aspect, the composite lift gate further includes an electronic component connected to the fiber assembly. In various aspects, the present disclosure provides a method of manufacturing a composite lift gate for a vehicle.

A garnish configured to enable use of a common door for a two-door vehicle and a four-door vehicle. The garnish may have a body. The body may be directly mountable onto a carriage of the two-door vehicle between an outer panel and a rocker panel of the two-door vehicle. The body may have an edge that is flush to a rear edge of the common door when mounted. The body may have at least two edges forming approximately a 90-degree angle.

An interfacing element of a lock zone of a door of a motor vehicle. The interfacing element comprises: includes a support made of plastic material, intended to be attached to a lining of the door, the lining being made of plastic material and a reinforcing plate of the lock zone onto which a lock is intended to be fastened, the plate being integrated to the support by overmolding. The support is made of a material having a Young's modulus lower than that of the plastic material of the lining of the door, and a coefficient of elongation at break greater than that of the plastic material of the lining of the door. A sub-assembly of motor vehicle includes a lining of tailgate and an interfacing element fastened onto an outer face of the lining.

A vehicle door according to an exemplary embodiment enhances coupling strength through structural coupling by molding a window frame of a door module assembled between a door trim and the door panel with a separate aluminum injection product, and insert-injection molding a coupling portion of the window frame to a module body, and a groove is formed along the coupling portion of the window frame coupled to the module body to easily distinguish respective parts and serve to carry out sealing in injection molding.
