Abstract

An airbag apparatus may include: a guide bar; a plurality of holders contacting the outer surface of the guide bar, and supporting the guide bar; a plurality of guide tabs connected to the respective holders, surrounding the guide bar; and a cushion connected to the holders on the opposite side of the guide taps.

Claims

1. An airbag apparatus comprising:

a guide bar;

a plurality of holders contacting an outer surface of the guide bar, and configured to support the guide bar;

a plurality of guide tabs connected to the respective plurality of holders, surrounding the guide bar; and

a cushion connected to the plurality of holders on an opposite side of the guide tabs.

2. The airbag apparatus of claim 1, wherein each of the plurality of holders comprises:

a holder body holding the guide bar therein; and

a pair of fixing protrusions formed on the holder body, contacting the guide bar, and configured to hold the guide bar in the holder body.

3. The airbag apparatus of claim 2, wherein the plurality of holders are formed in a longitudinal direction of the guide bar,

the holder body comprises a coupling protrusion formed at one surface of the holder body and a protrusion seating groove formed at another surface of the holder body, the protrusion seating groove corresponding to the coupling protrusion in the longitudinal direction of the guide bar, and

the holder body is fastened to two neighboring ones of the plurality of holder bodies through the coupling protrusion coupled with the protrusion seating groove on one of the two neighboring ones of the plurality of holder bodies, and the protrusion seating groove coupled with the coupling protrusion on another of the two neighboring ones of the plurality of holder bodies.

4. The airbag apparatus of claim 2, wherein the pair of fixing protrusions are arranged to face each other, a shortest distance between the pair of fixing protrusions is set to a value smaller than a diameter of the guide bar.

5. The airbag apparatus of claim 4, wherein the pair of fixing protrusions are formed of an elastically deformable material.

6. The airbag apparatus of claim 2, wherein the fixing protrusions comprise a rounded portion contacting the guide bar.

7. The airbag apparatus of claim 1, wherein the plurality of holders are formed of an elastically deformable material.

8. The airbag apparatus of claim 1, wherein each of the plurality of holders comprises a guide part around which a cushion winding part of the cushion is fixed on.

9. The airbag apparatus of claim 1, wherein the plurality of guide tabs are formed in a U-shape, and both ends of each of the plurality of guide tabs are connected to each of the plurality of holders.
