An impact beam 400 fixed to the 100 side is disposed. Further, a load transmission portion 600 is provided from the outer panel 100 to the door trim 300 corresponding to the frame portion 520 of the seat cushion 510 of the vehicle seat 500. The load transmitting portion 600 includes a first outer pad 610, a second outer pad 620, and a first trim pad 630, and applies a load to the frame portion 520 of the seat cushion 510 and moves the frame portion 520 when a side collision occurs. It has a function to make it.
According to the vehicle door having such a configuration, the first outer pad 610, the second outer pad 620, and the first trim pad 630 are arranged in the vehicle door, so that the frame portion 520 inside the seat cushion 510 is provided. Although the load is transmitted and the occupant is moved together with the vehicle seat 500, and the relative speed with the vehicle door can be reduced, the harmfulness to the occupant can be reduced, but there are the following problems. .

  First, when such a vehicle door structure is applied to a vehicle having a low seat position such as a coupe vehicle with the United States, as shown by an arrow, the vehicle is disposed within the input point of the harming vehicle and the vehicle. Since the positional relationship with the skeleton of the vehicle seat 500 is offset, that is, the input point of the harming vehicle and the frame portion 520 constituting the seat skeleton do not exist on the same axis, The first outer pad 610, the second outer pad 620, and the first trim pad 630 disposed in the vehicle door roll and fall down. Therefore, in the structure of such a vehicle door, the positional relationship of transmitting a load by closing the internal gap of the vehicle door is broken, and as a result, it is difficult to prevent the invading vehicle from entering.

  Secondly, in such a vehicle door structure, input from the side direction of the vehicle to be harmed at the time of a side collision is received by the frame portion 520 of the planar seat cushion 510. There was a difficulty of lowering.
