Description

  The present invention relates to a vehicle door, and more particularly to a vehicle door that can protect an occupant when a load such as a collision from the side is input.

FIG. 5 is a schematic diagram showing an example of a conventional door and an occupant. A seat 132 is disposed inside the vehicle door 104 so that the occupant 102 sits on the seat 132.
The door 104 includes an outer panel 110 that forms an outer plate of the vehicle, and an inner panel 108 that is disposed on the vehicle inner side of the outer panel 110 and forms an accommodation space such as a window glass (not shown) and a door lock system (not shown) together with the outer panel 110. And a door trim 106 attached to the inside of the inner panel 108 in the vehicle.

An energy absorbing member (hereinafter referred to as an EA member) 136 extending between the outer panel 110 and the inner panel 108 and between the inner panel 108 and the door trim 106 and extending in the vehicle front-rear direction at substantially the same height as the waist W of the occupant 102. Is arranged. Further, when a load is input from the side such as a collision from the side of the vehicle, a side airbag (SAB) 138 is activated between the occupant 102 and the door 104 to protect the occupant. Yes.
Further, in the vehicle shown in FIG. 5, the door glass (not shown) located above the door 104 is widened to improve the visibility, and at the same time the height of the belt line 134 is lowered, so that the occupant 102 is a general adult. In this case, the door 104 is structured such that the shoulder X is positioned above the belt line 134.

The impact received by the occupant when a vehicle having such a door 104 undergoes a side collision will be described with reference to FIG. FIG. 6 is an explanatory view of the impact received by the occupant when a vehicle having a conventional door 104 collides from the side, FIG. 6 (A) is a diagram showing the state before the collision, and FIG. FIG.
When the collision object 130 collides with the door 104 from the side from the state before the collision as shown in FIG. 6A, the side airbag 138 operates to protect the passenger 102. Then, as shown in FIG. 6B, the occupant 102 tilts to the outside of the vehicle due to the impact, and a large load is input to the chest Y located at the upper part of the door 104 and the waist part W located at the lower part of the door 104. In addition to high human body tolerance, the lumbar part can be protected because part of the load is absorbed by the EA member 136, but the chest is low human body resistant, so not only the side airbag 138 but further protection is required It is.

  The human body tolerance is high in the shoulder X and the waist W and low in the chest Y. Therefore, in order to protect the occupant 102 when the vehicle collides from the side, energy from the collision is transmitted to the shoulder X and the waist W having high human body resistance, and the occupant 102 enters from the door 104 entering the inside of the vehicle by the collision. It is necessary to secure a space between the chest Y and the door 104 in order to reduce the input to the chest Y with low human body resistance. However, in the door structure in which the shoulder portion is located above the belt line 134 as shown in FIG. 5, it is impossible to install the EA material at the contact position between the shoulder portion X and the door 104. It is difficult to input the load to the shoulder X and to secure a space between the chest Y and the door 104, and it is not possible to reduce the input to the chest Y having low human resistance.

For this reason, Patent Document 1 discloses a technique for inputting a load to a shoulder portion even in a door structure in which the shoulder portion of the occupant is above the belt line. FIG. 7 is a diagram showing an embodiment according to Patent Document 1. In FIG.
As shown in FIG. 7, in the upper part of the door trim 216c, an isolation composed of a movable panel (shock absorbing panel) 243 and an expansion / contraction mechanism (moving member) 244 formed of five cylindrical panels 441-445. Means 242 is arranged. Normally, the separating means 242 forms a part of the door trim, and when the vehicle collides with the side, the telescopic mechanism 244 is driven to move the movable panel 243 upward and as shown in FIG. The vehicle is configured to move inward of the vehicle so that a load is input to the shoulder of the occupant.

JP 2006-1383 A

However, in the technique disclosed in Patent Document 1, since the movable panel 243 that is an impact absorbing panel moves in the vehicle inner side direction, that is, the occupant direction, a large load is applied to the occupant when the movable panel 243 approaches the occupant, and the shoulder The burden on the department becomes excessively large. In particular, when the impact of a collision with a vehicle is large, the burden is large.
Further, since the expansion / contraction mechanism 244 is exposed to the outside when the separating means 242 is in operation, a part of the occupant's body is pinched between the cylindrical panels 441 to 445 constituting the expansion / contraction mechanism 244 due to the impact of the collision. There is a risk of adding.
Therefore, it cannot be said that it is sufficient in terms of safety improvement including reduction of the burden on the chest.

  Therefore, in view of such a problem of the prior art, the present invention transmits energy due to the collision to the shoulder and waist which are highly resistant to the human body, even in a vehicle where the belt line is lower than the shoulder of the occupant. A vehicle door which can secure a space between the chest and the door in order to keep the occupant away from the door entering the vehicle due to the collision and reduce the input of energy to the chest with low human resistance.
