A vehicle structure includes a body panel, a first spring anchor, a second spring anchor; and an elongated spring having a first end disposed at a first spring anchor and a second end disposed at a second spring anchor. The spring is preloaded when assembled to form an apex between the first end and the second end. The apex is disposed adjacent to the body panel to provide an outward force on the body panel.

An impact beam having a bent structure is provided. The impact beam is mounted at a lateral portion of each door in a vertical direction of a vehicle body and supports the door in the vertical direction. An upper end of the impact beam extends to support a roof panel and a lower end of the impact beam extends to a lower roller mounting portion. The impact beam is bent in an L shape and a T shape based on a curvature of the door.

A sliding door (12) for a vehicle (1) comprises an outer panel (21) defining an outer side surface of the vehicle, and an inner panel (22) joined to the outer panel along an outer periphery thereof, and having a central part spaced from the outer panel (21) on an inboard side of the outer panel. The inner panel includes a first inner wall portion (41, 51) extending forward from a rear edge of the inner panel and having a major plane facing laterally, and a second inner wall portion (42, 52) extending in an inboard direction from a front end of the first inner wall portion and having a major plane facing in a fore and aft direction, and a light emitter (81) or a reflector (91) is affixed to a rear surface of the second inner wall portion so as to irradiate light rearward.

An outer door panel and an inner door panel are fixed to one another defining a cavity therebetween. A door handle assembly is fixedly attached to the outer door panel, with at least a portion of the door handle assembly overlaying an inboard surface of the outer door panel within the cavity. An inboard portion of the door handle assembly has a connection structure. An upwardly extending bracket within the cavity is fixed to an upper end and a lower end of at least one of the inner door panel or the outer door panel. The upwardly extending bracket is spaced apart from the door handle assembly. A vibration absorbing member has a first end fixed to the connection structure of the door handle assembly and a second end attached to the upwardly extending bracket at a location spaced apart from upper and lower ends of the upwardly extending bracket.

A rigidity reinforcing structure for B-pillarless opposite sliding doors may include a column impact beam which is vertically mounted at one side of the door to support the door in an up-down direction of a vehicle; a center rail which is horizontally mounted at a center portion of the door to support the door in a front-rear direction of the vehicle and allows the door to slide; and a lower impact beam which is horizontally mounted at a lower side of the door to support the door in the front-rear rear direction and has one end portion where an intersection portion between the lower impact beam and the column impact beam is formed.

A vehicle bodywork panel is formed by an outer wall supported by a structural lining. The structural lining is produced by molding a plastic or composite material. The structural lining may include stiffeners arranged to provide said bodywork panel with a given amount of mechanical strength. One or more added connection elements connect separate fastening points disposed on the structural lining and each end of each of the connection elements is inserted into a housing disposed on a stiffener. The rigidity of the connection elements is adapted to suppress a vibration response of the stiffeners. The housing and the connection element may form a flush-mounted connection.

A sliding door (12) for a vehicle (1) comprises an outer panel (21) defining an outer side surface of the vehicle, and an inner panel (22) joined to the outer panel along an outer periphery thereof, and having a central part spaced from the outer panel (21) on an inboard side of the outer panel. The inner panel includes a first inner wall portion (41, 51) extending forward from a rear edge of the inner panel and having a major plane facing laterally, and a second inner wall portion (42, 52) extending in an inboard direction from a front end of the first inner wall portion and having a major plane facing in a fore and aft direction, and a light emitter (81) or a reflector (91) is affixed to a rear surface of the second inner wall portion so as to irradiate light rearward.

[Object] Provided is a configuration that makes up for a lack of tensile rigidity and a lack of collision properties at the same time.

[Solution] An automotive exterior panel according to the present invention: an exterior material 110; and a reinforcing member 120 that is in contact along an automobile inside surface of the exterior material 110 and of which a second moment of area in a direction orthogonal to the exterior material is less than or equal to 15,000 mm.sup.4 in a cross section orthogonal to a longitudinal direction of the reinforcing member. By this configuration, the second moment of area in a direction orthogonal to the longitudinal direction of the reinforcing member 120 is made less than or equal to 15,000 mm.sup.4, and hence a lack of tensile rigidity can be made up for at the same time.

A door system for a vehicle includes a vehicle body structure and a first door structure. The first door structure includes a first door beam extending between a lower part and an upper part of the vehicle body structure when the first door structure is closed. The first door beam includes a first engaging part arranged to interact with an essentially correspondingly shaped first receiving guide rail when the first door structure is in the closed position. The first receiving guide rail extends in a lateral direction of the vehicle body structure, aligned with an extension of a first cross member extending in a lateral direction of the vehicle body structure. Upon a side collision, the first door beam is arranged to engage with the first cross member and the receiving guide rail is arranged to prevent the first engaging part from moving in a vertical direction.

A door system for a vehicle includes a vehicle body structure and a first door structure. The first door structure includes a first door beam extending between a lower part and an upper part of the vehicle body structure when the first door structure is in a closed position. A first bracket is attached to a lower end of the first door beam. The first bracket is arranged to run in a first guide rail arranged in the vehicle body structure. The first guide rail includes a first recession. The first bracket includes a first protrusion arranged at a bottom end of the first bracket. Upon a roof crush, the first protrusion and the first recession in the first guide rail is arranged to engage to prevent separation of the first door structure from the vehicle body structure.
