Problems solved by technology

Therefore, when trying to improve aerodynamic performance and appearance by aligning the front pillar outer surface and the front quarter glass panel with each other to obtain a flat surface profile, it is impossible for the reinforcement to form two sides due to the limitation of the position of the flange. Ridge lines, the need to ensure sufficient mechanical strength of the reinforcement against axial forces can only be met by complicating the manufacturing process

Embodiment Construction

[0021] figure 1 It is a side view of a vehicle body incorporating a vehicle body side structure embodying the present invention. The vehicle body comprises sub-pillars 2 branching and hanging down from the middle portion of the front pillar 1 on each side of the vehicle body. A front windshield panel 3 is fitted between two front pillars 1 , and a triangular front triangular window glass panel 4 is fixedly fitted on each side in a triangular opening defined by the front pillar 1 and the sub-pillar 2 . The upper portion of the door sash 7 is located below the portion of the front pillar 1 extending behind the sub-pillar 2 and surrounds a door glass panel 6 that can be selectively rolled up and down from the door 5 .

Abstract

A vehicle body side structure that has a sub pillar (2) branched downward from a front pillar (1) and in which corner glass (4) is placed in front of the sub pillar (2). In the structure, the branch portion, from which the sub pillar (2) branches and in which the cross-sectional shape of the front pillar (1) varies, is prevented from becoming a weak point in strength to thereby increase the strength of the front pillar (1) against axial force. To achieve the above, a step-like wall section (23) having an installation surface (24) where the peripheral edge of the corner glass (4) is fixed is provided at that portion of an outer panel (11) that is in front of the sub pillar (2) and is near a joint section (17) on the corner glass (4) side. Further, two ridge sections (34, 35) extending in the longitudinal direction are formed on a stiffener (12) such that either of the two ridge sections (34, 35) is located on the inner side of the step-like wall section (23) of the outer panel (11). Thetwo ridge sections (34, 35), formed on the stiffener (12) at portions in front of the sub pillar (2), are continuous to two ridge sections (39, 40) formed at portions behind the sub pillar (2).

Description

technical field [0001] The present invention relates to a vehicle body side structure comprising a front pillar extending along a side of a front windshield panel, a sub-pillar depending from the front pillar, and a front quarter glass panel fitted in a front portion of the sub-pillar. Background technique [0002] The front pillar of the vehicle body is an important structural element that plays an important role in determining the stiffness and crash performance of the vehicle body, and it typically consists of a closed section member formed by joining outer panels, stiffeners, and inner panels along their side edges . Specifically, in a known structure, a reinforcing member is formed with a pair of ridges extending longitudinally thereof, thereby increasing its mechanical strength against axial force (refer to Japanese Patent No. 3074643). Therefore, in the event of a frontal collision, the impact load can be efficiently transmitted from the front upper member to the roo...
