Description

Technical Field [0001] The present invention relates to a Z-space insert apparatus for an airbag mounting module,

The present invention relates to an apparatus for fastening a reinforcing abrasive material to an airbag mounting module, in which a reinforcing abrasive material is disposed at a lower portion corresponding to a plurality of fasteners in a state where the airbag mounting module is fixedly arranged, To an apparatus for inserting a reinforcing wear member for an airbag mounting module that can be automatically engaged with an airbag mounting module and a reinforcing wear member as they are inserted at the same time.

Generally, automobiles have various safety devices to protect the safety of passengers. For example, there are safety belts, airbags, steering safety shafts, etc. Among these, Airbags mounted on the driver's seat and the passenger's seat are typical.

Background Art [0002] An airbag is generally mounted on a steering wheel of an automobile as a device for protecting a driver by reducing an impact applied to a driver in the event of a frontal collision of the vehicle.

In addition, a horn switch is mounted on the steering wheel so that the driver can hear a horn when an emergency occurs. In general, a thin-film horn switch is assembled to a lower portion of a mounting module having an airbag, When the horn switch is pressed, the horn sounds.

That is, since the airbag mounting module is continuously pressurized under the condition that the airbag mounting module is fastened to the coupling portion built in the steering wheel, the coupling portion is usually made of a material that is relatively softer than the airbag mounting module. There arises a problem that the engagement of the engagement portion and the airbag mounting module is loosened or the engagement portion is broken.

In order to prevent this, Applicants have found that the Z-space (hereinafter referred to as a "reinforcing abrasive material") made of a material having a ductility higher than that of the engaging member is mounted inside the airbag mounting module, So that the coupling force of the coupling portion and the airbag mounting module can be maintained for a long time.

A plurality of the reinforcing abrasive members are coupled to the airbag mounting module. Since the assembling processes of the reinforcing abrasive members are all manually performed, a considerable amount of time is required for the fastening, and the subsequent processes are delayed.

Also, since the size of the reinforcing abrasive is very small, it is difficult to fasten the novice, and it is also difficult to check whether the reinforcing abrasion material is fastened correctly, thereby increasing the defective rate of the manufactured airbag mounting module.
