Safety protector of vehicle steering column

Abstract

The invention relates to a security protection device for a vehicle steering column, which is used for preventing a steering wheel from falling down after the finish of the entire-vehicle collision; the invention can guide the crumpling of the steering column in the process of the entire-vehicle collision and can ensure the position of a safety airbag at the moment of detonation; the invention adopts the technical proposal that bending protection plates are arranged at two sides of the steering column and below the steering column; and the limit direction of the protection plates is same to that of the steering column. At the proper place of a steering column bracket which is used for connecting the steering column and the vehicle body, the invention arranges crumpling guide and anti-falling devices to prevent the steering wheel from falling down after the finish of the entire-vehicle collision, to guide the crumpling of the steering column in the process of the entire-vehicle collision, thereby ensuring the position of the safety airbag at the moment of detonation, and guaranteeing that the contact position of the human body and the airbag is closer to the designed theoretical position, and reducing the injury of the drivers caused by collision to the minimum extent.

Description

technical field [0001] The invention relates to auto parts, in particular to an auto steering column safety protection device. Background technique [0002] The steering wheel adjustable mechanism of automobiles has been basically popularized in the current models, but for the models with the steering column adjustment rotating pin at the lower end, the front collision (100% positive collision or 40% offset collision) When the collision occurs, the strong instantaneous external force during the collision will cause the axis of the steering column to shift, resulting in the position of the airbag cannot be guaranteed; in addition, the steering column and steering wheel after the collision collapse will fall on the driving surface due to lack of effective support. On the driver's seat, thereby bringing certain difficulties to the rescue work of the personnel, and may cause the secondary injury of the auto parts after the collision to the driver.
