A panel door applied for a vehicle including a stiffness member made of a plastic material and integrally formed on an internal surface of the panel door, includes an external panel, an internal panel coupled to the external panel, and a stiffness member formed to connect a frame forming a circumference and stiffness elements provided for reinforcing stiffness inside the frame and coupled to at least one of the external panel and the internal panel.

A door beam structure for a vehicle side door includes a door beam having a hollow cross section, wherein the door beam includes: an outside portion forming a hollow flange of the door beam arranged to face a door skin, and an inside portion forming a hollow door beam body of the door beam.

To make it possible to make impact absorption at the time of a collision even when there is no sufficient space.

[Solution] An impact absorption member according to the present invention includes: a member that is placed adjacent to an exterior material 110 of an automobile and in which a height in a direction orthogonal to the exterior material is larger than a width in a direction along the exterior material in a cross section orthogonal to an extending direction of the member. By this configuration, a first member 122 and a second member 124 are arranged so as to extend in different directions and be adjacent to the exterior material 110 of an automobile, and therefore impact absorption at the time of a collision can be made even when there is no sufficient space.

A door structure for a vehicle may include an external panel; an internal panel that is mounted to the external panel; and an impact member coupled to the internal panel between the external panel and the internal panel, wherein a protrusion that protrudes to an outside thereof toward a side external panel of a vehicle body from inside the internal panel is integrally provided in the impact member.

A vehicle door structure includes: a door inner including a body wall portion, a first opposed wall portion, and a second opposed wall portion; a door outer panel; an impact beam; an impact beam extension including a door-inner-side end portion and a fixed end; and a first reinforcement including a support portion fixed to the first opposed wall portion and a free end portion extending from the support portion toward the impact beam, wherein the impact beam extension and the free end portion are configured to be fitted to each other.

A vehicle includes a body and a door moveable relative to the body between the open and closed position. The vehicle includes a seat fixed relative to the door. The seat includes a seat back and a seat bottom. The body has a longitudinal axis, and the seat bottom extends from the seat back toward the longitudinal axis along a cross-vehicle direction perpendicular to the longitudinal axis when the door is in the closed position.

A door structure for a vehicle may include an external panel; an internal panel that is mounted to the external panel; and an impact member coupled to the internal panel between the external panel and the internal panel, wherein a protrusion that protrudes to an outside thereof toward a side external panel of a vehicle body from inside the internal panel is integrally provided in the impact member.

A panel door applied for a vehicle including a stiffness member made of a plastic material and integrally formed on an internal surface of the panel door, includes an external panel, an internal panel coupled to the external panel, and a stiffness member formed to connect a frame forming a circumference and stiffness elements provided for reinforcing stiffness inside the frame and coupled to at least one of the external panel and the internal panel.

A method of assembling vehicle-body components includes positioning a first component on a second component. The first component has a different coefficient of thermal expansion than the second component and one of the first and second components defines a slot. The method also includes loosely installing a bolt though the slot and the first and second components, and creating a joint in the first and second components. The method further includes heating the first and second components, which causes the first and second components to move relative to each other due to thermal expansion in response to the heating. This movement causes the joint to fail. The method also includes tightening the bolt.

A vehicle door is provided having an outer panel reinforced by a panel reinforcement and which is configured to generate low-frequency sound dominantly at the time of closing the door. The door has an outer panel openably/closably attached to a vehicle body by a front hinge; and a panel reinforcement extending in a vehicle front-rear direction on an inner side of the outer panel. The outer panel and the panel reinforcement are fixed by plural adhesion sections. The number of the adhesion sections in an upper area of the outer panel is larger than the number of the adhesion sections in a lower area of the outer panel. The number of the adhesion sections provided in a front lower area near the front hinge in the lower area is larger than the number of adhesion sections in a rear lower area away from the front hinge in the lower area.
