Abstract

The invention provides a door band course structure to improve relative fore-and-aft force reforming strength of door band course without adding weight, which is characterized by the following: setting strength component 16 along door band course 14 of front side entrance12; observing dent base of the strength component 16 along door band course from up-and-down direction of car body to display bending shape of fore-and-aft direction toward car broad inside projection; observing dent top of the door inside plate 24 along door band course from up-and-down direction of car body to display bending shape of fore-and-aft direction toward car broad inside projection; Hence, the centroidal P of closed cross-sectional structure 36 containing door inside plate 24 and strength component 16 bends projection shape toward inside car along the door band course.

Description

technical field [0001] The invention relates to a door waistline structure, in particular to a door waistline structure applicable to doors of vehicles such as automobiles. Background technique [0002] Conventionally, in the door waistline structure that can be used for the doors of vehicles such as automobiles, a reinforcement member composed of a roll-formed metal plate material is arranged along the waistline of the door inner panel of the front side door. A closed-section structure of two closed-section portions extending along the waistline has been disclosed (for example, refer to Patent Document 1.). [0003] Patent Document 1: JP-A-2000-355219 [0004] However, in this structure, when the vehicle collides in front and the front pillar moves backward, the reinforcing member arranged along the waistline of the front side door is sandwiched between the front pillar and the center pillar. At this time, at the front and rear end portions of the reinforcement, inner cor...
