Skeletal structure

Abstract

The present invention improves the strength of a skeletal structure. A skeletal structure (100) comprising a panel (1) and a frame (6) connected to a front surface side of the panel (1), said skeletalstructure (100) being characterized in that the frame (6) has a plurality of first frames (61, 62) oriented in a fixed direction and second frames (63, 64) oriented in a direction that is perpendicular to the first frames (61, 62); the first frames (61, 62) and the second frames (63, 64) are formed in a shape with an open cross-section; each of the first frames (61, 62) and the second frames (63,64) has a facing wall (621) that faces the panel (1), and a pair of side walls (622, 622) that stand up toward the panel (1) from both side sections of the facing wall (621); the plurality of first frames (61, 62) have, along the lengthwise direction thereof, connecting sections (s) that connect to the panel (1) and non-connecting sections (n) that do not connect to the panel (1); and the positions of all of the non-connecting sections (n) of the first frames (61, 62) with regard to the lengthwise direction of the first frames (61, 62) are matching or overlapping.

Description

technical field [0001] The present invention relates to a skeleton structure composed of panels and frames. Background technique [0002] Patent Documents 1 to 4 disclose a skeleton structure used for a backrest of a rear seat of a vehicle seat. Each of these framework structures includes a panel composed of a substantially rectangular metal plate, and a frame joined to the panel, and the frame uses a pipe provided along the outer edge of the panel. Furthermore, in the area where the frame is not provided among the panels of the frame structure, a plurality of ribs formed by protruding the metal plate are formed, and reinforcement by the ribs is performed.

Problems solved by technology

However, as in the frame structures described in Patent Documents 1 to 4, in frame structures using panels, if deformation occurs in the central part of the panels due to the impact of an object, the amount of deformation becomes the largest and there is a possibility that the panel may break. Case

Therefore, it is necessary to take countermeasures such as suppressing the deformation of the portion where the scale of destruction becomes large, or actively deforming the portion where the scale of destruction is difficult to become large, but the skeleton structures described in Patent Documents 1 to 4 do not take this into consideration.
