Abstract

Disclosed is an impact absorption steering apparatus, which includes: a mounting bracket for supporting an outer tube so as to fix the outer tube in a chassis of a vehicle; and a plate bracket which has one opened side and another side assembled with the mounting bracket, the plate bracket enclosing the outer tube, wherein the plate bracket is fixedly assembled with the mounting bracket, at least one protuberance is formed at an inner side of a guide part of the mounting bracket, and at least one groove is formed at each end of both sides of the plate bracket in such a manner that the groove corresponds to the protuberance.

Claims

1. An impact absorption steering apparatus, comprising:

a mounting bracket for supporting an outer tube so as to fix the outer tube in a chassis of a vehicle; and

a plate bracket which has one side opened and another side assembled with the mounting bracket, the plate bracket surrounding the outer tube,

wherein the plate bracket is fixedly assembled with the mounting bracket, at least one protuberance is formed at an inner side of a guide part of the mounting bracket, and at least one groove is formed at each end of both sides of the plate bracket in such a manner that the groove corresponds to the protuberance.

2. The impact absorption steering apparatus as claimed in claim 1, wherein the protuberance has a width larger than a width of the groove.

3. The impact absorption steering apparatus as claimed in claim 1, wherein the protuberance has a shape formed in such a manner that a uniform width and a predetermined length are successively formed, and then the width becomes smaller.

7. The impact absorption steering apparatus as claimed in claim 1, wherein at least one first molding groove is formed in such a manner that the first molding groove extends through the protuberance, a second molding groove is formed at the groove in such a manner that the second molding groove corresponds to the first molding groove, and a molding member is filled in the first molding groove and the second molding groove.

8. The impact absorption steering apparatus as claimed in claim 7, wherein the groove has a width smaller than a width of the plate bracket and a length which is longer than or equal to a length of the protuberance of the mounting bracket.

9. The impact absorption steering apparatus as claimed in claim 7, wherein the first molding groove and the second molding groove have a hole-shape.

10. The impact absorption steering apparatus as claimed in claim 7, wherein the first molding groove and the second molding groove have a slot-shape.

11. The impact absorption steering apparatus as claimed in claim 7, wherein the second molding groove is formed in such a manner the second molding groove reaches an inner part of a corner part of the plate bracket.

12. The impact absorption steering apparatus as claimed in claim 7, wherein the second molding groove is formed in such a manner the second molding groove extends through a corner part of the plate bracket.

4. An impact absorption steering apparatus, comprising:

a mounting bracket for supporting an outer tube so as to fix the outer tube in a chassis of a vehicle; and

a plate bracket which has one opened side and another side assembled with the mounting bracket, the plate bracket surrounding the outer tube,

wherein the plate bracket is fixedly assembled with the mounting bracket, at least one protuberance is formed at each end of both sides of the plate bracket, and at least one groove is formed at an inner side of a guide part of the mounting bracket in such a manner that the groove corresponds to the protuberance.

5. The impact absorption steering apparatus as claimed in claim 4, wherein the groove has a width smaller than a width of the protuberance.

6. The impact absorption steering apparatus as claimed in claim 4, wherein the groove has a shape formed in such a manner that a uniform width and a predetermined length is successively formed, and then the width becomes larger.
