[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door structure in which occupant safety is considered.

[0002]

2. Description of the Related Art With respect to the structure of an automobile door, various studies have been made on the structure of a door for a vehicle in order to ensure the safety of an occupant in the event of a side collision.

FIGS. 3 and 4 show an example of safety measures for a passenger of a conventional automobile door disclosed in Japanese Utility Model Laid-Open No. 4-74119. FIG. 3 is a front view of the door, and FIG. It is -A sectional drawing. As shown in the figure, in a space portion 13 formed by an outer panel 11 and an inner panel 12 of a window shoulder 10a of an automobile door 10, reinforcements extending in the front-rear direction of the vehicle body are respectively provided in the outer panel 11 and the inner panel 12. Closed section 1 by attaching plates 14 and 15
6 and 17 are formed to increase the rigidity of the window shoulder 10a of the door 10. This is because when the vehicle is subjected to a side collision, the closed cross sections 16, 17 of the window shoulder 10a are provided.
The rigidity of the door prevents the door 10 from being displaced into the vehicle due to the deformation of the door 10, and attempts to secure the occupant 18 in the vehicle.

[0004]

However, in the vehicle door according to the present invention, the closed cross sections 16 and 17 are used.
Is disposed over the entire front and rear body of the window shoulder 10a of the door 10. Further, since a sash for guiding the vertical movement of the window glass is generally attached to the reinforcing plate on the inner panel side, only a minimum necessary crash stroke is provided. Therefore, when the vehicle is subjected to a side collision, first, the door glass 19 is crushed, and the outer panel 11 having the closed section 16 is bent at the lower portion of the reinforcing plate 14 and enters the inside of the vehicle, while the closed section 16 of the outer panel is broken. Enters the inside of the vehicle in the same manner as described above, contacts the closed section 17 of the inner panel, and applies a load to the closed section 17. However, the door window shoulder 10a of the door is not deformed much because it is reinforced by the closed cross-sections 16 and 17, and the shock value near the shoulder of the occupant 18 is rather increased, which may adversely affect the occupant 18. There is.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the conventional automobile door, and an object of the invention is to provide an automobile door in which an occupant is safe during a side collision.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an automobile in which a closed cross section is formed by a reinforcing plate on an outer panel and an inner panel of a window shoulder to improve the rigidity of the window shoulder. In the door for the vehicle, a sash for guiding the rising and lowering of the windowpane is arranged between the trajectory of the windowpane and the outer panel, the upper end thereof is attached to the reinforcing panel of the outer panel, and the occupant shoulder at the window shoulder of the inner panel. For the portion corresponding to the vicinity, the above-mentioned reinforcing plate was cut off to form an open section.

[0007]

Since the door for a vehicle is constructed as described above, when a side collision is caused by another vehicle, the outer panel is bent inward from the lower part by the impact of the collision, and the window shoulder closed cross section of the outer panel is the inner side. Hit the panel.
At this time, most of the inner panel at the window shoulder receives the load of the closed section of the outer panel due to its closed cross section and suppresses deformation into the vehicle.However, near the shoulder of the occupant of the inner panel, the outer panel is closed. Since the position facing the cross-section is an open cross-section, the inner panel does not receive a large impact in this portion. That is, a sufficiently large crash stroke can be obtained between the closed section 2 of the outer panel 11 and the open section 5 of the inner panel 12, so that the impact force in the vicinity of the shoulder of the occupant is reduced, and the occupant receives physical shock. Damage is reduced.

[0008]

1 (a) is a sectional view of the vicinity of the occupant shoulder of an automobile door according to an embodiment of the present invention, FIG. 1 (b) is a sectional view of the occupant other than the vicinity of the shoulder, and FIG. FIG. 4 is an explanatory diagram showing a relationship position between an occupant and a door in FIG. As shown in FIG. 1, a vehicle door 10 according to the present invention has a space 13 formed by an outer panel 11 and an inner panel 12, and an outer panel 11 on a side of the window shoulder 10 a on the outer panel 11 side.
And a reinforcing plate 1 extending in a strip shape, a closed cross-section 2 is provided.
Thus, the closed section 4 is formed to increase the rigidity of the door window shoulder 10a.

In a space 13 formed by the outer panel 11 and the inner panel 12, a roller 19a provided below the window glass 19 by operating a window regulator (not shown).
Rolls in the sash 7, and the window glass 19 is stored along the vertical path 19b of the window glass. The sash 7 is disposed between the trajectory 19b of the windowpane and the outer panel 11, the upper part of the sash 7 fixes the bracket 8a to the reinforcing plate 1 with bolts 9, and the middle part is the side door beam 6 provided over the entire length of the door. In the lower part, the bracket 8c is fixed to one of the outer panel 11 and the inner panel 12 below the door with a bolt 9.

Therefore, the window shoulder 10 of the outer panel 11
5A, the closed cross-section 2 is formed continuously in the front-rear direction of the vehicle body, but in the inner panel 12, the closed cross-section 4 is not formed over the entire length of the door in the front-rear direction. In the vicinity 12a of the shoulder of the occupant 18,
The reinforcing plate 3 is missing and an open section 5 is formed.

The automobile door 10 constructed as described above.
When the vehicle is subjected to a side collision, the glass 19 of the door is first shattered by the impact of the collision at the window shoulder 10a of the door 10, and then bends at the lower portion of the outer panel 11 and enters the vehicle. At that time, the closed section 2 of the outer panel 11 enters the vehicle similarly to the above, and the inner panel 1 of the window shoulder 10a.
However, since the reinforcing plate 3 is cut off near the shoulder 12a of the occupant 18 to form the open section 5, the closed section 2 of the outer panel 11 and the inner panel 12
Crash stroke between the open section 5 of the
Therefore, the vicinity 12 of the shoulder of the occupant 18 of the inner panel 12
In a, the impact force applied to the occupant 18 in the event of a side collision is reduced. Therefore, the impact value near the shoulder of the occupant 18 hardly increases.

[0012]

According to the present invention, a closed section is formed by a reinforcing plate on the outer panel and the inner panel of the window shoulder to guide the ascending and descending of the window glass in an automobile door in which the rigidity of the window shoulder is improved. A sash is arranged between the elevating locus of the windowpane and the outer panel, and the upper end thereof is attached to the reinforcing plate of the outer panel. Because it was dropped and the cross section was open, when the vehicle was subjected to a side collision, near the shoulder of the occupant, there was little impact due to the closed cross section of the outer panel that bent inside the vehicle due to the impact of the collision,
Therefore, the shock to the occupants was reduced, and the excellent effect of ensuring the occupants' safety was obtained.
