A vehicle door for use in a vehicle body comprising a rocker (20) is described. The vehicle door comprises an inner door panel (11) and an outer door panel (13), wherein the door further comprises a reinforcement element (12) arranged in a lower portion of the door such that when the door is mounted in the vehicle body, the reinforcement element (12) is at the height of the rocker (20) and such that when a side impact is received by the door the reinforcement element with the inner door panel is supported by the vehicle rocker. The reinforcement element (12) is a U-shaped bracket that extends from the inner door panel (11) to the outer door panel (13), the U-shaped bracket (12) being arranged with an open side facing the inner panel. The disclosure further relates to a vehicle having a vehicle body that comprises a rocker and such a door.

A steel composition, a reinforcement part of a vehicle using the steel composition and a method of manufacturing the reinforcement part using the steel composition are provided. In particular, the steel composition includes increased content of carbon components and the steel composition is processed by rapid heating and immediate quenching.

The disclosure relates to a crash structure for a motor vehicle, the crash structure being, in a starting state, at a minimum spacing of greater than zero from a door hinge of a vehicle door of the motor vehicle, and the crash structure being in contact with at least one contact region which is assigned to the door hinge in a crash state after a partial overlap crash by way of passing into an operative connection with a wheel of the motor vehicle, and forming a deflector surface for the deflection of the wheel.

A steel composition, a reinforcement part of a vehicle using the steel composition and a method of manufacturing the reinforcement part using the steel composition are provided. In particular, the steel composition includes increased content of carbon components and the steel composition is processed by rapid heating and immediate quenching.

A door of a vehicle may include a first door module forming a door skeleton; and a second door module coupled with the first door module and forming a door window; wherein the second door module includes a relatively lightweight material as compared to the first door module; a reinforcement member is inserted along an edge portion forming the door window of the second door module; and a stepped portion is formed at the reinforcement member, reducing weight and cost of the door of the vehicle.

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.

A vehicle-body structure of a vehicle comprises a front side door provided so as to open and close an opening portion for entrance which is formed by a vehicle-body frame member. The front side door comprises a door panel portion and reinforcement portions provided at a peripheral part of the door panel portion such that at least part of the reinforcement portions overlaps with the vehicle-body frame member in a vehicle side view, the reinforcement portions being configured to reinforce the door panel portion such that when a collision load is inputted to the front side door in a vehicle side collision, a connection state of the door panel portion and the vehicle-body frame member is maintained.

There are provided a vehicle-body frame member forming an opening portion for entrance at a vehicle side part and a front side door provided so as to open and close the opening portion. The vehicle-body frame member comprises a side sill, the front side door comprises a door panel portion provided with an inner lower portion which overlaps with the side sill in a vehicle wide view and reinforcement portions provided at three side-portions of a peripheral part of the door panel portion which are continuous and include the inner lower portion such that the reinforcement portions overlap with the vehicle-body frame member in a vehicle side view.

The invention relates to a motor vehicle door locking system, comprising a motor vehicle door lock (1) on a motor vehicle door (2) and a lock retainer (3), interacting therewith, on a motor vehicle body (4), or vice versa, according to patent application DE 10 2014 007 119.7, characterized in that a hold-back element (5) is provided which keeps clear an inlet opening (6) for the lock retainer (3) in the motor vehicle door lock (1) even in the event of deformations of the motor vehicle door (2) caused by an accident, wherein the hold-back element (5) keeps the opening clear on account of a shaping of the hold-back element.

A door lock assembly for a vehicle door includes a door panel, a stiffener bracket, a lock assembly, and a door pad. The door panel includes an inner door panel and an outer door panel. A stiffener bracket is connected to the inner door panel. A lock assembly is connected to the inner door panel. A door pad is connected to the stiffener bracket. The door pad is configured to interfere with the lock assembly to prevent the lock assembly from unlocking the vehicle door upon an object impacting the outer door panel.
