Abstract

A steering system of an automobile may include a mounting bracket having a flange portion supporting a steering column and contacting with an automobile body, and an opening hole formed at the flange portion and opening toward one side of the flange portion, a capsule slidably coupled to the opening hole and adapted to be decoupled from the opening hole when an impact is given thereto, and at least one molded supporter fixing the capsule and the flange portion and adapted to be sheared off from the capsule or the flange portion when the impact is given thereto.

Claims

1. A steering system of an automobile comprising:

a mounting bracket having;

a flange portion supporting a steering column and contacting with an automobile body; and

an opening hole formed at the flange portion and opening toward one side of the flange portion;

a capsule slidably coupled to the opening hole and adapted to be decoupled from the opening hole when an impact is given thereto; and

at least one molded supporter fixing the capsule and the flange portion and adapted to be sheared off from the capsule or the flange portion when the impact is given thereto.

2. The steering system of claim 1, wherein the at least one molded supporter is formed by solidifying molten resin after filling a space between the capsule and the flange portion with the molten resin.

3. The steering system of claim 1, wherein a pair of molded supporters is provided along both sides of the opening hole on which the capsule is configured to slide.

4. The steering system of claim 1, wherein at least one stepped portion for receiving the molten resin is dented at the flange portion along a side of the opening hole on which the capsule is configured to slide.

5. The steering system of claim 4, wherein a first insertion hole is formed on and is connected to the at least one stepped portion, and the first insertion hole is adapted to receive the molten resin.

6. The steering system of claim 5, wherein the at least one molded supporter includes a first supporting portion corresponding to the at least one stepped portion and a second supporting portion corresponding to the first insertion hole.

7. The steering system of claim 1, wherein a second injection hole is formed at a portion of the capsule contacting with the flange portion, and the molten resin is injected through the second injection hole.

8. The steering system of claim 7, wherein a molded pin is formed by solidifying the molten resin filling with the second injection hole, and the molded pin fixes the capsule to the molded supporter and is adapted to be sheared off by the impact.

9. The system of claim 1, wherein a distance between both sides of the opening hole becomes wider toward the one side.

10. The system of claim 9, wherein the both sides of the opening hole form an angle of about 8°

to 12°

.

11. The system of claim 1, wherein the capsule includes a slide groove to slidably receive the at least one molded supporter therein.

12. A steering system of an automobile comprising:

a mounting bracket having;

a flange portion contacting with an automobile body; and

an opening hole formed at the flange portion and opening toward one side of the flange portion;

a capsule slidably coupled to the opening hole and adapted to be decoupled from the opening hole when an impact is given;

at least one molded supporter fixing the capsule and the flange portion and adapted to be sheared off from the capsule or the flange portion when the impact is given; and

at least one molded pin fixing the molded supporter to the capsule and adapted to be sheared off by the impact.

13. The steering system of claim 12, wherein at least one stepped portion is dented at the flange portion along a side of the opening hole on which the capsule is adapted to slide, and

wherein the at least one molded supporter is formed by solidifying molten resin after filling the stepped portion with the molten resin.

14. The steering system of claim 12, wherein a first insertion hole connected to the at least one stepped portion and receiving the molten resin is formed on the at least one stepped portion.

15. The steering system of claim 14, wherein the at least one molded supporter includes a first supporting portion corresponding to the at least one stepped portion and a second supporting portion corresponding to the first insertion hole.

16. The steering system of claim 12, wherein a second injection hole is formed at a portion of the capsule contacting with the flange portion, and the molten resin is injected through the second injection hole.

17. The steering system of claim 16, wherein the molded pin is formed by solidifying the molten resin filling with the second injection hole.

18. The system of claim 12, wherein a distance between both sides of the opening hole becomes wider toward the one side.

19. The system of claim 18, wherein the both sides of the opening hole form an angle of about 8°

to 12°

.

20. The system of claim 12, wherein the capsule includes a slide groove to slidably receive the at least one molded supporter therein.
