Abstract

A vertically extending upright pillar sash of a vehicle door frame is formed by combining a first member which includes a glass run channel, for holding a glass run, on an inner peripheral side of the door frame, and a second member which includes a portion projecting toward a vehicle interior with respect to the glass run channel. The first member and the second member each includes facing portions that are spaced from each other and face each other in a direction connecting the inner peripheral side and an outer peripheral side of the door frame, and fixing portions that are provided at the upper part of the upright pillar sash by overlaying the facing portions on each other and fixing the facing portions to each other in the direction connecting the inner peripheral side and the outer peripheral side of the door frame.

First claim

The invention claimed is:

1. A vehicle door frame comprising an upright pillar sash extending in a vertical direction and an upper sash joined to a joining surface formed on an upper part of said upright pillar sash to form a door corner portion,
wherein said upright pillar sash is formed by combining a first member which includes a glass run channel, for holding a glass run, on an inner peripheral side of said door frame, and a second member which includes a portion projecting toward a vehicle interior with respect to said glass run channel,
wherein said first member and said second member each includes facing portions which are spaced from each other and face each other in a direction connecting said inner peripheral side and an outer peripheral side of said door frame, and fixing portions which are provided at said upper part of said upright pillar sash by overlaying said facing portions on each other and fixing said facing portions to each other in said direction connecting said inner peripheral side and said outer peripheral side of said door frame, and
wherein said fixing portions include a portion of said first member that is cut and raised, further wherein said portion being cut and raised is fixed on said second member.

2. The vehicle door frame according to claim 1 , wherein said first member includes a channel portion which constitutes said glass run channel, and a design portion which is positioned on a vehicle exterior side of said channel portion,
wherein said second member includes said portion projecting toward a vehicle interior, a design portion which is positioned closer to a vehicle exterior than said portion projecting toward a vehicle interior; and a connecting portion which connects said design portion and said portion projecting toward a vehicle interior, and
wherein said channel portion of said first member and said connecting portion of said second member are fixed to each other at said fixing portions.

3. The vehicle door frame according to claim 2 , wherein, in addition to being fixed via said fixing portions, said first member and said second member are fixed to each other at mutual ends of said design portions of said first member and said second member and at ends of said channel portion and said portion projecting toward a vehicle interior.

4. The vehicle door frame according claim 1 , wherein said first member is formed by roll forming, and
wherein said second member is formed by press forming.

5. The vehicle door frame according to claim 1 , wherein said portion projecting toward the vehicle interior comprises:
an inner peripheral side wall and an outer peripheral side wall which are spaced from each other toward said inner peripheral side and said outer peripheral side of said door frame, respectively, and face each other;
a vehicle interior side wall which connects vehicle interior side ends of said inner peripheral side wall and said outer peripheral side wall; and
an extension wall which is extended toward said inner peripheral side of said door frame from said inner peripheral side wall.

6. The vehicle door frame according to claim 5 , wherein said extension wall projects toward said inner peripheral side of said door frame relative to said glass run channel in said door corner portion.

7. The vehicle door frame according to claim 5 , wherein said extension wall is formed up to an upper end of said upright pillar sash.

8. The vehicle door frame according to claim 5 , wherein, in said portion projecting toward the vehicle interior where said fixing portions are formed, a width between said outer peripheral side wall and said inner peripheral side wall in a direction connecting said inner peripheral side and an outer peripheral side of said door frame is larger than a width between said outer peripheral side wall and said inner peripheral side wall in said portion projecting toward the vehicle interior where the fixing portions are not formed.

9. The vehicle door frame according to claim 1 , wherein said fixing portions include a fixing lug from said first member and a connecting wall of said second member.

10. The vehicle door frame according to claim 9 , wherein said fixing lug is cut and raised from said first member.
