This disclosure relates to a vehicle door, and specifically, to an attachment structure of a lower part of a door sash of the vehicle door.
An example of a background vehicle door is described with reference to FIGS. 6 to 8. FIG. 6 is a configuration view of a vehicle door, which is seen from a vehicle interior, FIG. 7 is a cross-sectional view taken along a line VII-VII of FIG. 6, and FIG. 8 is an enlarged view of a part VIII of FIG. 6.
As shown in FIG. 6, an upper part of a vehicle door 1 is provided with a door sash 3 that holds a door glass. As shown in FIGS. 6 and 7, a lower part of the door 1 is configured by an outer panel 5 and an inner panel 7.
As shown in FIGS. 6 to 8, a vehicle interior face of a lower part of the door sash 3 and the inner panel 7 are connected via a bracket 9. In the meantime, the bracket 9 also serves as a base to which a lock device and the like of the door are attached.
Also, patches 16A and 16B may be attached to the bracket 9 so as to reinforce a part of the bracket 9 of which strength is relatively weak (for example, refer to JP-A-2008-168707).
Regarding the vehicle door having the above configuration, a sufficient attachment length (a length L in FIG. 8) of the door sash 3 and the bracket 9 may not be secured due to a shape of the vehicle door and a shape of the lock device attached to the bracket 9.
In this case, the attachment strength of the door sash 3 and the bracket 9 becomes insufficient and thus stiffness of the lower part of the door sash 3 is deficient. Therefore, the door sash 3 may be drawn towards a vehicle exterior upon high-speed traveling.
This disclosure provides at least a vehicle door where the attachment strength of a door sash and a bracket is improved and the stiffness of the chassis is improved.
A vehicle door of this disclosure includes: a door sash; a bracket, which joins the door sash to an inner panel; and a patch, which is joined to the bracket and the door sash and which sandwiches the door sash in cooperation with the bracket, thereby reinforcing the bracket.
The other features of this disclosure will be further clarified from an illustrative embodiment of this disclosure to be described later and the accompanying drawings.
According to this disclosure, the patch is joined to the bracket and the door sash, sandwiches the door sash in cooperation with the bracket and reinforces the bracket. Thereby, the attachment strength of a lower part of the door sash and the bracket is improved and the stiffness of the door sash is improved.
The other effects of this disclosure will be further clarified from an illustrative embodiment of this disclosure to be described later and the accompanying drawings.
