Problems solved by technology

[0006] However, in the structure disclosed in this Patent Document 3, deformation or destruction in the delamination direction, which has the highest risk of strength weakening, is generally presupposed in the fiber-reinforced resin structure. Utilize the high mechanical properties that were originally aimed at
In other words, it becomes a structure that sacrifices the high mechanical properties originally aimed at

Embodiment Construction

[0031] Embodiments of the present invention will be described below.

[0032] figure 1 , figure 2 An embodiment of the present invention is shown, particularly a case where the fiber-reinforced resin structure of the present invention is configured as a frame structure for a seat back of a vehicle seat. exist figure 1 , figure 2 In the figure, reference numeral 1 denotes a frame structure for a seat back of a vehicle seat as an example of the fiber-reinforced resin structure of the present invention. The seat back frame structure 1 is constituted as an integral molded body of a fiber-reinforced resin structure using carbon fibers as reinforcing fibers. On both sides of the lower part of the frame structure 1 for the seat back, there are respectively provided in the approximately horizontal direction a connecting member (for example, a bolt) for connecting to other members, such as the rotation adjustment member 4 constituting a part of the seat frame 3 , to be inserted. ...

Abstract

A fiber-reinforced resin structure having a hole into which a connector that connects to another member is inserted. Said fiber-reinforced resin structure is characterized in that the bearing strength of the part of the inside surface of the hole on which the load from the connector acts, represented by the stress at which deformation of said part starts increasing even without the load acting on said part from the connector increasing, is less than the breaking strength of the fiber-reinforced resin constituting that part of the structure. This makes it possible, without increasing the number of components or assembly steps, for the structure to exhibit good mechanical properties while absorbing external loads such as impact energy with extremely high efficiency via localized deformation or displacement only, with no accompanying breakage.

Description

technical field [0001] The present invention relates to a fiber-reinforced resin structure, and more particularly to a fiber-reinforced resin structure having a hole for inserting a connecting member, for example, to a frame structure for a seat back suitable for a vehicle part, preferably a vehicle seat, etc. A fiber-reinforced resin structure, the connector is used to connect with other components. Background technique [0002] In recent years, structures made of fiber-reinforced resins have been used in various fields requiring high-strength properties and lightweight properties. Fiber-reinforced resins can achieve extremely high strength and rigidity, but they can cause brittle fractures and local fractures in response to impact loads. In areas where such fractures are undesirable, they are designed so that the The additional mechanism, for example, the member that connects the fiber-reinforced resin structure to another member is deformed or broken first, or the additi...
