Abstract

A crash pad including an air-bag-door-opening part is provided, which includes a crash pad base, an air-bag-door-opening part, which is positioned so as to face air-bag doors disposed on the crash pad base, and an opening-inducing groove, which is formed along an opening line of the air-bag-door-opening part.

First claim

What is claimed is:

1. A crash pad including an air-bag-door-opening part, comprising:
a crash pad base;
an air-bag-door-opening part, which is positioned so as to face air-bag doors disposed on the crash pad base; and
an opening-inducing groove, which is formed along an opening line of the air-bag-door-opening part,
wherein the opening-inducing groove comprises:
an upper groove positioned in an upper surface of the crash pad base; and
a lower groove positioned in a lower surface of the crash pad base adjacent to the upper groove in a vertical direction on the crash pad base.

2. The crash pad of claim 1 , further comprising at least one reinforcing portion disposed in the opening-inducing groove formed in a rear surface of the air-bag-door-opening part.

3. The crash pad of claim 1 , further comprising a cutout portion positioned at a region at which the air-bag doors meet each other.

4. The crash pad of claim 3 , wherein the cutout portion is positioned at the opening line along which the air-bag-door-opening part is opened.

5. The crash pad of claim 1 , wherein the lower groove is configured such that a width of a cross-section thereof is decreased moving upwards in a thickness direction of the crash pad base.

6. The crash pad of claim 1 , further comprising a connecting portion, which is disposed between the upper groove and the lower groove and which is integrally formed with the crash pad base.

7. The crash pad of claim 1 , further comprising a foam layer disposed on an upper surface of the crash pad base.

8. The crash pad of claim 7 , further comprising a skin layer disposed on an upper surface of the foam layer.

9. The crash pad of claim 7 , wherein the upper groove is formed so as to abut on the foam layer, and at least a portion of the foam layer is configured to be depressed in an inward direction of the upper groove so as to compensate for volume loss and thus to prevent thermal deformation.

10. The crash pad of claim 1 , wherein the lower groove is configured to have a cross-section, which includes a left part and a right part, divided based on the connecting portion, the left part and the right part having different cross-sectional areas.

11. The crash pad of claim 10 , wherein one of the left and right parts has a cross-sectional area that is 20% to 30% smaller than a cross-sectional area of a remaining one of the left and right parts.
