AI Technical Summary
Technical Problem
Conventional driver airbags have a complex assembly process due to the integration of multiple parts such as the horn guide, horn spring, and horn rod, leading to increased part count, assembly tolerances, and extended fitting times, which can impair cost competitiveness.
Method used
A driver airbag design that integrates the electrode unit into the mounting plate and uses a connector on the cover to connect to the anode and cathode, eliminating the need for a horn guide, horn spring, and horn rod, with a simplified assembly process.
Benefits of technology
Reduces the number of parts and simplifies the assembly process, thereby improving quality control and reducing assembly time and costs.

Abstract
Driver airbag comprising: a mounting plate (110) mounted on a steering wheel instrument (101); a cover (120) coupled to the mounting plate (110) in a way that allows it to be raised and lowered; an elastic element (130) installed between the mounting plate (110) and the cover (120) to apply an elastic force to the cover (120); an electrode assembly (140) installed in the mounting plate (110); and a connector (150) installed on the cover (120) and connected to the electrode assembly (140) when the cover (120) is lowered, the electrode assembly (140) comprising: an anode (141) installed such that it is exposed towards the outer surface of the mounting plate (110);and a cathode (143) which is installed such that it is exposed towards the outer surface of the mounting plate (110) and is separated from the anode (141), wherein the connector is simultaneously connected to the anode (141) and the cathode (143) when the cover (120) is lowered. wherein the anode (141) has a horizontally extending anode extension (141a), the cathode (143) may have a horizontally extending cathode extension (143a), and the anode extension (141a) and the cathode extension (143a) are separated from each other, characterized in that the connector (150) has: a connector body (151) which is attached to the underside of the cover (120); and an elastic connecting part (153) extending from the connector body (151) and arranged facing the anode extension (141a) and the cathode extension (143a).
