Problems solved by technology

[0004] In the structures described in each patent document, the mechanism for installing the airbag module on the steering wheel by both the dynamic damping function and the buckle method is quite complicated and requires a large number of parts. Therefore, it is hoped that at this point take countermeasures

Embodiment Construction

[0027] figure 1 In the middle, 1 is the core bone of the steering wheel. The core bone 1 has a hub portion 1a. As will be described later, the airbag module 10 is mounted on the hub portion 1a.

[0028] Such as image 3 As shown, in the hub portions 1a of the steering wheel (the core bone 1), a plurality of (three embodiments) hook portion 2 is protruding in the rear (rear of the steering wheel in a state in the vehicle). form. Each hook 2 is formed integrally with the core bone 1, for example, by casting. Each hook 2 has a tondary distal distal portion 2a. The expanded distal portion 2a functions as a locking claw. Further, the circumferential designation position in the side of each hook portion 2 is formed as a flat surface 2b.

[0029] The reset spring 3 composed of a coil spring is mounted on the outer circumference of the hook portion 2. The reset spring 3 is restricted from the hook portion 2 from the hook portion 2 based on the enlarged distal portion 2a of the hook portio...

Abstract

The steering wheel structure includes: a cylindrical guide (30) held in a mounting hole (12a) formed on the mounting plate portion (12) of the airbag module (10); a hook portion (2) formed on the steering wheel (1) and inserted into the guide (30); damping rubber (20), installed between the edge of the mounting hole (12a) of the mounting plate (12) and the guide (30); and locking The spring (40) is held by the guide (30). The locking spring (40) is locked on the hook (2) inserted into the guide (30), so as to limit the hook (2) from detaching from the guide (30).

Description

Technical field [0001] The present invention relates to a steering wheel structure. Background technique [0002] The driver's seat airbag is usually mounted to the hub of the steering wheel after being modified. The modular driver's space with the airbag (hereinafter referred to as the airbag module) is mounted to the mounting method of the steering wheel, is known to have a simple installation of the Snap-Inmethod. Further, in order to achieve dynamic vibration damping function, the vibration of the steering wheel in the travel is reduced, and the airbag module as a mass body is elastically mounted on the steering wheel. [0003] Patent Document 1 and Patent Document 2 discloses the following configuration: the airbag module can be mounted to the steering wheel without both the dynamic damping function and the buckle mode. [0004] In the structures described in each patent document, it is possible to realize the dynamic vibration damping function and the mounting of the airbag...
